Anti-scale kho cov dej khib nyiab evaporator

Kev kho cov yeeb yaj kiab ua ntej los tiv thaiv nplai yog nqa tawm thaum cov dej khib nyiab evaporator ua. Thaum cov dej khib nyiab evaporator tau tsim, cov yeeb yaj kiab tiv thaiv tuaj yeem tsim rau ntawm qhov chaw ntawm cov kav dej ntawm cov evaporator thiab cov chiller, uas tuaj yeem tiv thaiv cov fouling siv lead ua los ntawm kev txuas rau ntawm cov yeeb nkab tooj liab, txo qhov muaj peev xwm ntawm qhov tsim. nyob rau hauv cov dej khib nyiab evaporator, thiab txuas ntxiv cov txheej txheem ntawm cov dej khib nyiab evaporator thiab cov chiller. (2) Lub pre-txias yog teem rau hauv cov dej khib nyiab evaporator thiab lub chiller, kom lub evaporation kub ntawm lub raj ntawm cov dej khib nyiab evaporator yog qis dua 40 degree, thiab tib lub sij hawm, cov dej ntau thiab siv zog. dej distributor yog siv los xyuas kom meej tias qhov chaw ntawm lub condenser raj yog ib txwm them los ntawm cov yeeb yaj kiab dej thiab tsis muaj qhov chaw qhuav. Kev teeb tsa lub precooler thiab tiv thaiv cov cim ntawm cov ntsiab lus qhuav muaj kev tiv thaiv ntawm qhov teeb meem scaling ntawm evaporator thiab cua txias. (3) Ib qho me me ntawm cov twj tso kua dej tsis tu ncua yog siv los tswj qhov sib piv ntawm calcium ions hauv cov dej txias ntawm cov dej khib nyiab thiab cov cua txias hauv ib qho chaw, tiv thaiv cov nag lossis daus. Txo cov ntsiab lus ntawm calcium ions nyob rau hauv cov dej txias ntawm evaporator, chiller thiab kaw txias ntauwd yog txoj hauv kev zoo tshaj plaws los tswj cov teeb meem nplai, thiab tuaj yeem daws qhov teeb meem ntawm kev tiv thaiv nplai thiab nplai tsim hauv cov dej khib nyiab evaporator los ntawm qhov chaw.
