Go deimhin, tá baint ag éifeacht atomization an atomizing nozzle le go leor gnéithe, agus bíonn tionchar difriúil ag foirmeacha éagsúla atomizing nozzle air, mar shampla:
1. atomizer brú
Nuair a úsáidtear brú atomizing nozzle (díreach agus lártheifeacha) chun titim deannaigh spraeála a dhéanamh, braitheann an éifeachtacht bhaint deannaigh go príomha ar bhrú an tsoláthair uisce, agus tá brú uisce méideanna cáithníní éagsúla difriúil le haghaidh úsáide cinnte. Dá airde brú an deannaigh míne, is airde an brú. Ní féidir leis an brú ard soláthair uisce, ní hamháin ceo uisce fíneáil na gcáithníní a fháil, ach freisin go mbeidh luas gluaiseachta ard agus cion uisce spáis mór ag na cáithníní ceo uisce, atá an-tairbheach don mhodh laghdaithe deannaigh bunaithe ar mheicníocht imbhuailte. De réir na gceanglas maidir le scaipeadh cáithníní deannaigh iarbhír agus éifeachtúlacht laghdaithe deannaigh, is féidir torthaí maithe agus na buntáistí eacnamaíocha is fearr a bhaint amach ag tagairt don chuar comhfhreagrach chun an brú uisce cuí a roghnú. Tá an chonclúid infheidhme maidir le haon ionad oibre ina n-úsáidtear an nozzle spraeála atomizing brú chun deannach guail a spraeáil agus a réiteach.
2. atomizer dhá chéim
① Influence of mixing tube diameter and length: the smaller inner diameter of mixing tube can increase the relative velocity of gas-liquid two phases, which is conducive to atomization, but it will affect the re aggregation of atomized particles. Because the mixing tube is too long and the gas energy loss is too much, the atomization of liquid flow will become worse; If the mixing tube is too short, the gas energy can not be fully utilized, resulting in insufficient atomization of liquid flow.
② Effect of nozzle: because reducing the outlet area will increase the outlet pressure drop, the acceleration of gas-liquid mixture is significantly enhanced, and the relative velocity of gas-liquid phase increases, which also makes the liquid phase break finer. However, the increase of outlet pressure drop will inevitably increase the pressure in the mixing pipe, resulting in the decrease of the relative velocity of gas-liquid two phases in the mixing pipe, which will make the atomization worse.
③ Relationship between gas-liquid ratio and atomized particle size: with the increase of gas-liquid ratio, the atomized particle size decreases. Therefore, increasing the gas-liquid ratio can increase the relative velocity of gas-liquid two phases and make the liquid film break finer. However, when the gas-liquid ratio increases to a certain extent, the change of particle size is not obvious.
④ Change of droplet concentration with gas-liquid ratio: with the increase of gas-liquid ratio, the particle concentration of water decreases, which is caused by the decrease of water mass fraction in air
