1 Precision Spray Nozzles for the Chemical Industry

2 PROSS OPTIMIZATION WIT NOZZL TCNOLOGY Any company that wants to keep ahead of the competition needs to constantly optimize its production processes. In automated systems, even minor discrepancies can provide optimization opportunities. Nozzle and spray technology is a good example. The best results are achieved where nozzle technology is optimally tailored to individual requirements. This requires a full understanding of the processes involved especially in the chemical industry. At Lechler, we have been maintaining this expertise for over 135 years. As early as when his trading company was founded in 1879, Paul Lechler believed in chemistry. Initially the main focus was on technical products, machine oils and wood preservatives, and in 1905 the company gained exclusive sales rights to the protective coating Inertol. y 1919 he had added his selfproduced protective coatings to this portfolio. In 1961, all chemical products were finally combined in a separate company. Today Lechler offers a wide product range for the optimization of technical processes. The following pages will provide you with several examples of this. Throughout our history, chemistry has played a major role in our company. Over the course of many decades, this gave rise to a unique understanding of spraying and atomization processes. We are familiar with a wide range of applications at various pressures, temperatures and atmospheres Company founded by Paul Lechler Patent for liquid atomization Relocation of production from ad Cannstatt to Feuerbach Sales offices founded in Germany Company existence: 14 years 79 years 83 years

5 Cleaning containers Optimum container cleaning requires targeted harmonization with the customized application. Lechler offers a wide range of rotating nozzles and will support you in finding the right arrangement. System and large tank cleaning igh impact tank cleaning machines can be used in this application. These traverse a precisely defined path with gearcontrolled solid stream nozzles. This gives them a great range. In smaller containers and systems, the precision jets can remove even persistent dirt. Nozzles for air cooling and humidification The thermodynamic processes of evaporation is normally applied in air cooling and humidification. This requires fine droplets that are injected directly into the air / gas flow by hollow cone or cluster nozzles. Producing the suitable droplet size and even distribution over the intake channel are particularly important here. 5

6 LCLR NOZZLS AR US IN MANY FILS IN T CMIL INUSTRY Tank sprinklers and fire protection For cooling and sprinkling tanks and systems, it is extremely important to spray the entire object with water on all sides or to provide an even water film on the object. The narrowest cross section of the nozzles should be 6 mm (IN 14495). Tonguetype nozzles and full cone nozzles are frequently used. roplet separators roplets can be carried along in the gas flow during the absorption process. Lechler droplet separators remove droplets from the gas flow in order to prevent downstream measuring devices from being affected. Special full cone nozzles are available for cleaning droplet separators. Gas cooling (Quenching) In gas cooling, a liquid is added via nozzles that, under some circumstances, evaporates completely and thereby absorbs the thermal energy of the gas. Complete evaporation requires very fine droplets which can be produced with hollow cone or twinfluid nozzles. 6

7 Absorption (Gas washing) If the waste gas is to undergo absorption, Lechler full cone, hollow cone, or cluster nozzles are used. It is of crucial importance here to create a large specific reaction surface. The efficiency of the process can be decisively enhanced by making the right nozzle selection and having an optimum nozzle arrangement. Material separation in centrifuges Centrifuges are used to separate materials. Full cone and flat fan nozzles are used for that in order to spray on water to wash out the material that is to be removed. 7

8 WAT YOU SOUL KP IN MIN WN PLANNING Nozzle selection criteria: Atomization methods Flow rate, spray pattern/ angle and spraying behavior Liquid distribution Viscosity Gases Narrowest cross section roplet sizes Ambient conditions Materials 10 Connections 11 Material wear 12 Mechanical cleaning elow we have compiled a list of the most important criteria for selecting your nozzle. 1 Atomization methods Singlefluid nozzles spray small to very large volumes of liquid solely via pressure. This makes them suitable above all for lowviscosity (e.g. water, alcohols) to slightly viscous (e.g. olive oil) fluids and, depending on the jet shape, pressure and flow rate, they produce fine to very coarse droplets. Since only one fluid flow must be handled, singlefluid nozzles are comparatively easy to install and use. The typical pressures are between 0.5 and 20 bar. In most cases, higher differential pressures than 20 bar are used in singlefluid nozzles only for atomizing viscous products or in cleaning technology. Figure 1: ifferent spray characters Twinfluid nozzles atomize the liquid with the aid of a compressible medium, in most cases compressed air or steam. They work in the range of very small to medium flow rates and are preferred for particularly fine misting or the atomization of highviscosity liquids. A distinction is made between twinfluid nozzles with internal mixing and those with external mixing. The combining of two different fluid flows makes the installation and operating complexity greater than is the case with comparable singlefluid nozzles. 2 Flow rate, spray pattern/angle, spraying behavior Unless otherwise stated, the flow rate information for our nozzles always refers to water. The conversion of differing liquid densities is explained in our standard catalogue. epending on the version and application, we supply singlefluid nozzles with differently stepped spray angles from 0 (solid stream nozzles) to 360 (tank cleaning nozzles). The quoted spray angles apply in close vicinity to the nozzle orifice and without external influences. Gravity and air flows influence the spray pattern. epending on the version, singlefluid nozzles can spray the fluid as a hollow cone, full cone or flat fan. The solid stream nozzle does not spray, but rather produces a closed jet that hits at a concentrated point. The jet only eight of the nozzle position mm begins to break up after some distance. Twinfluid nozzles have a narrow spray angle of due to the high speed at which the compressible medium exits. owever, as the distance from the nozzle increases, the spray pattern becomes increasingly less sharply delimited. Twinfluid nozzles normally produce full cone or flat fan spray patterns. The diagram above illustrates how height influences the spray pattern. Changing the nozzle pressure Pressure: Very low Spraying direction Spraying upwards Pressure: Optimum mm Pressure: Very high Spraying downwards orizontal spraying 8

9 3 Liquid distribution 4 Viscosity owever, due to the compressibility and lower density, the spray pattern of gases can not be formed in the same manner as liquids. An even liquid distribution is crucial to processes such as coating. This requires several nozzles to be arranged next to each other. This is because whereas a single nozzle would produce a parabolic liquid distribution, several nozzles arranged next to each other allow an almost even distribution via overlapping. Increased viscosity of the fluid can reduce the flow rate, changes the spray pattern (narrower spraying angle) and allows the droplet spectrum to become coarser. epending on the fluid properties, it is possible to counteract this to a certain extent by means of higher pressure. For very viscous substances, it is recommended to use twinfluid nozzles in most cases. It can also be helpful to take account of the fluid's rheology. Figure 4: Atomization of gelatin with a Lechler ViscoMist twinfluid nozzle Under certain conditions (pressure and nozzle geometry), gases tend to significantly increase the sound level. The turbulences that cause the discharge noise are significantly reduced by applying multichannel nozzles with specially shaped nozzle openings. This nozzle geometry also increases the blowing force while at the same time reducing the air consumption. In some circumstances, the velocity of gases can be very high. If a certain pressure difference is applied to a nozzle, velocities of around 320 m/s can often arise in the narrowest cross section. This velocity can even increase briefly after the nozzle. The chart below shows the velocity curve in a flow situation. 6 Narrowest cross section The risk of a nozzle blocking depends greatly on its narrowest cross section ( ). xperience has shown that for smooth operation, the maximum particle size in the fluid should not exceed one third of the narrowest cross section. Narrowest cross section ischarge hole Figure 7: Narrowest cross section Figure 3: Fluid distribution measurement Measuring the distribution The liquid distribution in a plane can be determined with the aid of a combination of Plexiglas cylinders. The filling level of the individual cylinders is determined fully automatically. This measuring process can also record the liquid distribution of a nozzle over a moving measuring plane. This enables conveyor belt spraying to be simulated, for example. 5 Gases Fundamentally, the delivery of gases (e.g. air) must be regarded in a differed way to that of liquids. Gases are compressible fluids, whereas liquids are incompressible fluids. Gases can be delivered with almost all nozzles with which liquids are also atomized. Incompressible Compressible ollow cone and full cone nozzles with axial flow have an internal swirl. ollow cone and full cone nozzles with inflow at the side (tangential or eccentric design) do not need a swirl and are, therefore, much less prone to blockages. In the field of flat fan nozzles, our tonguetype nozzles represent a special design that is less susceptible to blockages.

10 WAT YOU SOUL KP IN MIN WN PLANNING 7 roplet sizes The following generally applies: Within a series and at a given pressure, nozzles with a lower flow rate produce finer droplet spectrums than nozzles with a higher flow rate. Twinfluid nozzles can produce very fine to extremely fine droplets. The size depends mainly on the flow rate ratio of the compressible medium used (m 3 /h) to the atomized fluid (l/min): The greater the ratio, the finer the atomization. In the case of singlefluid nozzles, however, the decisive factors are pressure, nozzle type and flow rate across the droplet spectrum. Increasing pressure results in finer atomization, but mostly only up to a certain level. ollow cone nozzles produce very fine to fine droplets at the same pressure and flow rate. Full cone nozzles produce slightly coarser droplet spectrums, and finally flat fan nozzles have the coarsest droplet spectrum. 8 Ambient conditions The environment being sprayed into is a decisive criterion for which spray angle, pressure, material or droplet size should be selected for the process. If the surrounding gas circulates around a nozzle, this can have a direct influence on the trajectory of the droplets and therefore on the process. Influencing factors in the environment include, for example pressure and temperature, gas type (e.g. air or SO 2 ), dimensions (e.g. in the case of containers) or other parameters. X Also for example, when cleaning containers it is essential to pay attention as to whether a flammable mixture can form in the tank. If this is the case, Lechler tank cleaners with ATX approval can be used. 9 Materials k Material wear Our standard materials for metallic nozzles are brass and the stainless steels (AISI 303, AISI 316L and AISI 316Ti). Standard nozzles made of plastic are mostly made of PA, PVF or POM. For special mechanical, thermal or chemical loads, we supply a wide variety of special materials, for example acidresistant or heatresistant stainless steels, special alloys, ceramic materials or plastics such as PP, P1000 or PTF. It is also necessary to select the optimum material for the seals. Viton, PTF, PM or WP are used, depending on the applications. owever, sealing materials such as Inconel or Centellen are also used for special cases. 10 Connections Nozzles are mainly manufactured with threads conforming to ISO 228, IN 2999 (N ) and NPT. A distinction is made here between sealing and nonsealing threads. In the case of nonsealing threads, Teflon strip or a thread paste is used to provide the seal. Nozzle wear depends greatly on the conditions of use and on the nozzle material. Normally, the nozzle's fluid dis charge opening wears as a result of material abrasion. The following conditions of use can speed up wear: Amount and hardness of the particles in the fluid Operating the nozzle above the recommended pressure range Using aggressive substances As wear increases, the spray pattern quality becomes continuously worse. In most cases, this can be seen very easily with the naked eye. At the same time, a change occurs in the spraying parameters, for example an increased flow rate. Wear leads to a worse production result and higher costs. Fig. 10 shows an example of a heavily worn spray ball. For these reasons, regular maintenance intervals and nozzle replacement are particularly important for achieving constant process capability. Figure 8: roplet measurement roplet size range This shows the ranges in which droplets can in general, be roughly categorized. Sauter diameter d µm extremely fine 50 µm 100 µm 300 µm 500 µm 800 µm very fine fine medium coarse very coarse roplet size range 1100 µm 2000 µm 3000 µm Not all nozzles can be connected with a thread. For these we supply flange solutions conforming to IN 2527, N and ASM Aseptic clamp connections (TriClamp connections) conforming to IN are also possible. Whether a connection other than the standard connection is feasible for a nozzle must be be determined individually. Figure 10: Chemical attack on a spray ball Figure 9: roplet size definition 10

11 l Mechanical cleaning Cleaning effects Rotating cleaning nozzles deliver the greatest possible impact in order to clean the container wall. To achieve this, large droplets must strike at high speed. This even allows the cleaning of persistent dirt that would usually not dissolve. Important influencing variables are the distance between the nozzle and wall, and the operating pressure. Neither must be too great or the fluid will break down into smaller droplets (see Figs. 11 and 12) and the impact will be reduced. esides the impact, the fluid running down the container wall also has a significant cleaning effect. If the formed film is thick enough, the resulting shear stresses can remove light to moderate dirt. In that case, unsprayed patches are less of an issue than is the case during impact cleaning (see Fig. 5). Rotating cleaning nozzles or spray ball? ue to their simple construction, spray balls are economical and are resistant to faults. Whereas rotating cleaning nozzles spray the entire container wall in a fanlike pattern, the jets from spray balls strike only in concentrated spots. The remaining surface is simply cleaned by the shear stresses of the fluid running off (see Fig. 14). The cleaning process can also take much longer, depending on the type and degree of dirt. Cost reduction via efficient cleaning processes This is precisely where our nozzles and rotating cleaning nozzles come into play, having been specially developed for delivering a high mechanical cleaning action. Their greater efficiency helps to permanently reduce on going costs for energy and cleaning agents, and also the duration of cleaning. Consequently a oneoff investment in improved nozzle technology pays for itself after only a short time. a Impact and shearing power MIN bar MAX Figure 11: Rotating cleaning nozzles with recommended operating pressure b Agitator Shearing power Figure 13: Cleaning mechanisms, impact and shearing power Cleaning effect MIN bar MAX Figure 12: Rotating cleaning nozzles with operating pressure too high Cleaning effect a b istance Figure 14: Cleaning with a spray ball 11
