AAny company thatwants to keep ahead of

the competition needs

to constantly optimize

its production proces-

ses. 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.

P ROC ESS O PT I M I Z AT I ON W I TH NO ZZ LE T E CH NO LOGY

As early as when his tradingcompany was founded in 1879,Paul Lechler believed in chemistry. Initially the mainfocus was on technical products,machine oils and wood preser-vatives, and in 1905 the com-pany gained exclusive salesrights to the protective coatingInertol®. By 1919 he had addedhis self-produced protectivecoatings to this portfolio. In1961, all chemical productswere finally combined in a separate company.

Today Lechler offers a wideproduct range for the optimiza-tion of technical processes. The following pages will provideyou with several examples ofthis.

Throughout our history, chemis-try has played a major role inour company. Over the courseof many decades, this gave riseto a unique understanding ofspraying and atomization processes. We are familiar witha wide range of applications atvarious pressures, temperaturesand atmospheres.

Our products are characte-rised by maximum precisionand reproducibility. Today wesupply not only a unique selection of readily availablestandard nozzles, but alsohave the know-how for making customized products.

We would also be very plea-sed to advise you in personabout how you can make yourown processes even more ef-ficient.

Cleaning containers

Optimum containercleaning requires targetedharmonization with the customized application.Lechler offers a wide rangeof rotating nozzles andwill support you in findingthe right arrangement.

System and large tankcleaning

High impact tank cleaning machines can be used in thisapplication. These traverse a precisely defined path with gear-controlled solid streamnozzles. 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 evaporationis normally applied in air cooling and humidification. This requires fine droplets thatare injected directly into the air / gas flow by hollow cone or cluster nozzles. Producingthe suitable droplet size and even distributionover the intake channel are particularly important here.

Droplet separators

Droplets can be carriedalong in the gas flow during the absorption process. Lechler dropletseparators remove droplets from the gas flowin order to prevent down-stream measuring devicesfrom being affected. Special full cone nozzlesare available for cleaning droplet separators.

Gas cooling (Quenching)

In gas cooling, a liquid is added via nozzles that, undersome circumstances, evaporates completely and therebyabsorbs the thermal energy of the gas. Complete evapo-ration requires very fine droplets which can be produced with hollow cone or twin-fluid nozzles.

Tank sprinklers and fireprotection

For cooling and sprinklingtanks and systems, it is ex-tremely important to spraythe entire object with wateron all sides or to providean even water film on theobject. The narrowest crosssection of the nozzlesshould be ≥ 6 mm (DIN 14495). Tongue-typenozzles and full conenozzles are frequentlyused.

6

Material separation incentrifuges

Centrifuges are used to separate materials. Fullcone and flat fan nozzlesare used for that in order to spray on water to washout the material that is tobe removed.

7

Absorption (Gas washing)

If the waste gas is to undergo absorption, Lechler fullcone, 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 enhancedby making the right nozzle selection and having an optimum nozzle arrange-ment.

The quoted spray anglesapply in close vicinity to thenozzle orifice and without ex-ternal influences. Gravity andair flows influence the spraypattern. Depending on theversion, single-fluid nozzlescan spray the fluid as a hollowcone, full cone or flat fan.

The solid stream nozzle does not spray, but rather producesa closed jet that hits at a con-centrated point. The jet only

begins to break up after somedistance.

Twin-fluid nozzles have anarrow spray angle of 20° -40° due to the high speed atwhich the compressible medium exits. However, as the distance from the nozzle increases, the spray patternbecomes increasingly lesssharply delimited. Twin-fluidnozzles normally produce fullcone or flat fan spray patterns.

Twin-fluid nozzles atomizethe liquid with the aid of acompressible medium, inmost cases compressed air orsteam.They work in the range of verysmall to medium flow ratesand are preferred for particu-larly fine misting or the atomi-zation of high-viscosity liquids.

A distinction is made betweentwin-fluid nozzles with internalmixing and those with externalmixing. The combining of twodifferent fluid flows makes theinstallation and operatingcomplexity greater than is thecase with comparable single-fluid nozzles.

Flow rate,spray pattern/angle,spraying behavior

Unless otherwise stated, theflow rate information for ournozzles always refers to water.The conversion of differingliquid densities is explained inour standard catalogue.

Depending on the version andapplication, we supply single-fluid nozzles with differentlystepped spray angles from 0°(solid stream nozzles) to 360°(tank cleaning nozzles).

Below we have compiled a listof the most important criteriafor selecting your nozzle.

Atomization methods

Single-fluid nozzles spraysmall to very large volumes ofliquid solely via pressure. Thismakes them suitable above allfor low-viscosity (e.g. water, al-cohols) to slightly viscous (e.g.olive oil) fluids and, dependingon the jet shape, pressure andflow rate, they produce fine tovery coarse droplets. Since onlyone fluid flow must be hand-led, single-fluid nozzles arecomparatively easy to installand use.

The typical pressures are bet-ween 0.5 and 20 bar. In mostcases, higher differential pres-sures than 20 bar are used insingle-fluid nozzles only foratomizing viscous products orin cleaning technology.

Narrowest cross section

The risk of a nozzle blockingdepends greatly on its narro-west cross section (Ø E). Ex-perience has shown that forsmooth operation, the maxi-mum particle size in the fluidshould not exceed one thirdof the narrowest cross section.

Hollow cone and full conenozzles with axial flow havean internal swirl. Hollow coneand full cone nozzles with in-flow at the side (tangential oreccentric design) do not needa swirl and are, therefore,much less prone to blockages.In the field of flat fan nozzles,our tongue-type nozzles represent a special designthat is less susceptible toblockages.

Liquid distribution

An even liquid distribution iscrucial to processes such ascoating. This requires severalnozzles to be arranged next toeach other. This is becausewhereas a single nozzlewould produce a parabolic liquid distribution, severalnozzles arranged next to eachother allow an almost evendistribution via overlapping.

Measuring the distribution

The liquid distribution in aplane can be determined withthe aid of a combination ofPlexiglas cylinders. The fillinglevel of the individual cylin-ders is determined fully auto-matically. This measuringprocess can also record the liquid distribution of a nozzleover a moving measuringplane. This enables conveyorbelt spraying to be simulated,for example.

3 Viscosity

Increased viscosity of the fluidcan reduce the flow rate,changes the spray pattern(narrower spraying angle) andallows the droplet spectrum tobecome coarser.

Depending on the fluid pro-perties, it is possible to coun-teract this to a certain extentby means of higher pressure.For very viscous substances, itis recommended to use twin-fluid nozzles in most cases. Itcan also be helpful to take ac-count of the fluid's rheology.

Gases

Fundamentally, the delivery ofgases (e.g. air) must be regar-ded in a differed way to that ofliquids. Gases are compressi-ble fluids, whereas liquids areincompressible fluids.Gases can be delivered withalmost all nozzles with whichliquids are also atomized.

4 However, due to the compres-sibility and lower density, thespray pattern of gases can notbe formed in the same man-ner as liquids.

Under certain conditions(pressure and nozzle geome-try), gases tend to significantlyincrease the sound level. Theturbulences that cause thedischarge noise are signifi-cantly reduced by applyingmulti-channel nozzles withspecially shaped nozzle ope-nings. This nozzle geometryalso increases the blowingforce while at the same timereducing the air consumption.

In some circumstances, thevelocity of gases can be veryhigh. If a certain pressure dif-ference is applied to a nozzle,velocities of around 320 m/scan often arise in the narro-west cross section. This velo-city can even increase brieflyafter the nozzle. The chartbelow shows the velocitycurve in a flow situation.

Droplet sizes

Twin-fluid nozzles can pro-duce very fine to extremelyfine droplets. The size dependsmainly on the flow rate ratio ofthe compressible mediumused (m3/h) to the atomizedfluid (l/min): The greater theratio, the finer the atomization.

In the case of single-fluidnozzles, however, the decisivefactors are pressure, nozzletype and flow rate across thedroplet spectrum. Increasingpressure results in finer atomi-zation, but mostly only up to acertain level.

Hollow cone nozzles pro-duce very fine to fine dropletsat the same pressure and flowrate. Full cone nozzles pro-duce slightly coarser dropletspectrums, and finally flat fannozzles have the coarsestdroplet spectrum.

7 The following generally ap-plies: Within a series and at agiven pressure, nozzles with alower flow rate produce finerdroplet spectrums than nozz-les with a higher flow rate.

Ambient conditions

The environment beingsprayed into is a decisive cri-terion for which spray angle,pressure, material or dropletsize should be selected for theprocess. If the surroundinggas circulates around anozzle, this can have a directinfluence on the trajectory ofthe droplets and therefore on the process. Influencing factors in the environment include, for example pressureand temperature, gas type(e.g. air or SO2), dimensions(e.g. in the case of containers)or other parameters.

Also for example, whencleaning containers it is es-sential to pay attention as towhether a flammable mixturecan form in the tank. If this isthe case, Lechler tank cleanerswith ATEX approval can beused.

Materials

Our standard materials formetallic nozzles are brass andthe stainless steels (AISI 303,AISI 316L and AISI 316Ti).Standard nozzles made of plastic are mostly made of PA,PVDF or POM. For specialmechanical, thermal or chemi-cal loads, we supply a widevariety of special materials, forexample acid-resistant orheat-resistant stainless steels,special alloys, ceramic materi-als or plastics such as PP,PE1000 or PTFE.

It is also necessary to selectthe optimum material for theseals. Viton, PTFE, EPDM orEWP are used, depending onthe applications. However,sealing materials such as Inconel or Centellen are alsoused for special cases.

Connections

Nozzles are mainly manufac-tured with threads conforming to ISO 228, DIN 2999 (EN 10226-1) and NPT. A distinction is made herebetween sealing and non-sea-ling threads. In the case ofnon-sealing threads, Teflon®strip or a thread paste is usedto provide the seal.

Not all nozzles can be connected with a thread. For these we supply flangesolutions conforming to DIN 2527, EN 1092-1 andASME B 16.5. Aseptic clampconnections (Tri-Clamp con-nections) conforming to DIN 11864-3 are also possible.Whether a connection otherthan the standard connectionis feasible for a nozzle mustbe be determined individually.

9 k Material wear

Nozzle wear depends greatlyon the conditions of use andon the nozzle material. Nor-mally, the nozzle's fluid dis -charge opening wears as aresult of material abrasion.The following conditions ofuse can speed up wear:

n Amount and hardness ofthe particles in the fluid

n Operating the nozzle abovethe recommended pressurerange

n Using aggressive substan-ces

As wear increases, the spraypattern quality becomes continuously worse. In mostcases, this can be seen veryeasily with the naked eye. At the same time, a changeoccurs in the spraying parameters, for example anincreased flow rate.

Wear leads to a worse pro-duction result and highercosts. Fig. 10 shows an exam-ple of a heavily worn sprayball. For these reasons, regu-lar maintenance intervals andnozzle replacement are parti-cularly important for achievingconstant process capability.

Cleaning effects

Rotating cleaning nozzles deliver the greatest possibleimpact in order to clean thecontainer wall. To achieve this,large droplets must strike athigh speed. This even allowsthe cleaning of persistent dirtthat would usually not dissolve.Important influencing varia-bles are the distance betweenthe nozzle and wall, and theoperating pressure. Neithermust be too great or the fluidwill break down into smaller

If the formedfilm is thick enough, the resul-ting shear stresses can re-move light to moderate dirt. Inthat case, unsprayed patchesare less of an issue than is thecase during impact cleaning(see Fig. 5).

Rotating cleaning nozzles orspray ball?

Due to their simple construc-tion, spray balls are economi-cal and are resistant to faults.Whereas rotating cleaningnozzles spray the entire con-tainer wall in a fan-like pattern,the jets from spray balls strikeonly in concentrated spots.The remaining surface is sim-ply cleaned by the shearstresses of the fluid runningoff (see Fig. 14). The cleaningprocess can also take muchlonger, depending on the typeand degree of dirt.

Cost reduction via efficientcleaning processes

This is precisely where ournozzles and rotating cleaningnozzles come into play, ha-ving been specially developedfor delivering a high mechani-cal cleaning action. Theirgreater efficiency helps to permanently reduce on goingcosts for energy and cleaningagents, and also the durationof cleaning. Consequently aone-off investment in impro-ved nozzle technology paysfor itself after only a short time.
