Cov laj thawj thiab kev kho mob ntawm kev hloov pauv tsis txaus hauv tshuab evaporator ntawm chiller
Cov evaporator yog ib qho ntawm plaub qho loj ntawm cov tshuab chiller. Cov evaporator yog cov pa hluav taws kub tawm uas tso cai rau cov kua dej uas tsis tshua muaj kua txias los pauv cov cua kub nrog qhov nruab nrab uas yuav tsum tau muab tso rau hauv tub yees. Tej zaum muaj ob qho laj thawj rau kev hloov pauv kub tsis txaus ntawm chiller evaporator: 1. Evaporation Cov dej ntws tsis txaus hauv cov evaporator, 2. Cov teeb meem txawv teb chaws hauv cov evaporator yog thaiv (lossis nplaim ntawm cov raj hauv evaporator hauv cov evaporator yog scaled lossis crystallized,) ua rau kub pauv tsis txaus)
1. Cov dej ntws tsis txaus hauv cov evaporator:
Lub hauv paus tseem ceeb uas ua rau muaj qhov tshwm sim no yog qhov tsis ua hauj lwm ntawm lub taub dej los yog nkag teb chaws ntawm qhov teeb meem txawv teb chaws nyob rau hauv lub luag haujlwm ntawm lub tshuab tso dej, los yog cov dej xau ntawm lub qhov dej ntawm lub twj tso kua dej (uas nyuaj rau kev kuaj thiab xav tau kev soj ntsuam kom zoo ), ua rau dej ntws tsis txaus.
Kev Kho Mob: hloov cov twj tso dej tawm, los yog disassemble cov twj tso kua dej kom tshem tawm cov teeb meem txawv teb chaws hauv lub tshuab raj, ces qhov txhaum tuaj yeem tshem tawm.
2. Lub tshuab evaporator txhaws lossis fouled:
Txhawm rau txiav txim siab seb lub tshuab nqus dej puas los yog lub tshuab raj evaporator tau fouled, qhov teeb meem ntawm lub taub dej tso tawm yuav tsum tau muab tshem tawm ua ntej, thiab nws tuaj yeem txiav txim siab tom qab paub tseeb tias lub tshuab nqus dej thiab cov kav dej hauv lub raj xa dej ib txwm. Cov evaporator blockage lossis cov qauv ua muaj qhov sib xws thiab pom tseeb (tsuas yog siv rau lub nruab nrab-txias chillers): thaum cov khoom siv yog ib txwm, yuav tsis muaj qhov loj ntawm kem lossis dej khov lossis dej khov rau saum npoo ntawm lub tshuab pa. Thaum koj pom ntau lub hws lossis dej khov nyob rau saum npoo ntawm lub tshuab pa, nws tuaj yeem txiav txim siab tias cov evaporator txhaws.
Kev Kho Mob: Yog tias lub tshuab raj evaporator txhaws lossis lub raj raj evaporator raug txhim kho, lub tshuab raj evaporator yuav tsum tau tawg, thiab lub raj evaporator yuav tsum tsis ntim khoom thiab muab yaug nrog rab phom dej siab lossis nqus dej hauv cov kua tshuaj tshwj xeeb.
Nco tseg: Qee cov evaporator siv cov tshuaj ua kua, xws li cov tub yees hauv cov hlau oxidation (anodic oxidation) ua cov nroj tsuag. Cov evaporators muaj cov kua dej sulfuric acid. Thaum qee qhov xwm txheej tau mus txog, cov kua roj sulfuric acid yuav quaj thiab thaiv. Yog hais tias tus evaporator yog txhaws los ntawm cov ntshiab ntshiab sulfuric acid muaju, ntev li ntev tau cov dej kub siab tshaj 50 degrees yog daim pa hauv cov evaporator, lub iav ci tuaj yeem yaj. Qee qhov yog siv hauv cov tshuab ntoo electroplating, xws li acid zinc plating. Qee cov ntsiab lus acidic zinc plating muaj" potassium chloride" ;. Thaum" potassium chloride" kua kis tau los ntawm cov nplauv ntawm lub raj raj ntawm lub tshuab raj evaporator, qhov kub saum npoo ntawm lub raj evaporation yog qhov tsawg heev (hauv qab qhov kub tsis txaus), uas yuav ua rau"" Potassium chloride" precipitates muaju, cov muaju no yuav qhwv cov raj evaporator nrog txheej tuab" potassium chloride" cov khaub ncaws ntau dhau sijhawm, ua rau cov evaporator poob nws cov peev txheej txauv thaum tshav kub kub. Tus menyuam yaus yog pom tias muaj peev xwm ua kom tsis muaj qhov tso hauv tub yees, thiab hauv cov xwm txheej hnyav nws ua rau lub zog poob qis. (Hauv qhov no, kev xaiv tsis raug nyob rau ntawm lub sijhawm ntawm kev yuav khoom)
