Phaj tshav kub exchanger yog ib qho compact, txuag hluav taws xob hloov khoom siv, nws muaj kev hloov pauv hluav taws xob siab (nws cov hluav taws xob hloov hluav taws xob ntau dua li lub raj xa hluav taws xob yog 3 mus rau 5 npaug siab dua), npog thaj tsam me me (rau lub raj kub hloov pauv 1 / 3), lub neej ntev kev pab cuam, me me peev, yooj yim rau scale, txhim khu kev qha thiab ruaj thiab lwm yam.
Nyob rau hauv xyoo tas los no, nws tau siv dav hauv metallurgy, roj av, tshuaj, shipping, textile, tshuaj, tshuaj, zaub mov thiab lwm yam lag luam, yog kom paub txog cov cua sov, txias, cua sov rov qab, ceev sterilization thiab lwm yam kev siv cov khoom zoo heev. Txawm li cas los xij, vim tias lub phaj kub hloov pauv qhov kub hloov pauv tau siab dua (tshwj xeeb tshaj yog chav sib pauv), thiab nws cov hluav taws xob hloov hluav taws xob siab, yog li nws yooj yim heev los ntsuas. Nyob rau tib lub sij hawm phaj kub exchanger sab hauv kev ncig aperture yog me me, tom qab scaling lub internal channel cross-section yuav me me los yog txawm blocked, uas ua rau lub phaj kub exchanger tshav kub hloov efficiency yog txo, yog li cuam tshuam rau cov khoom ib txwm muaj thiab cov cuab yeej muaj kev ruaj ntseg. Yog li ntawd, lub phaj kub exchanger yuav tsum tsis tu ncua tshuaj ntxuav, tshem tawm cov av, thiaj li yuav xyuas kom meej tias lub phaj kub exchanger npaum kub hloov thiab ib txwm tsim.
Phaj kub exchanger yog ib tug nyias hlau phaj (feem ntau stainless hlau) nias rau hauv ib tug tej yam zoo li corrugated tshav kub exchanger phaj, thiab ces ntxiv ib tug sealant gasket stacked rau hauv lub tshav kub exchanger. Feem ntau yog los ntawm lub tshav kub hloov phaj, sealing gasket, clamping bolts, compression phaj, tag nrho cov ncej thiab lwm yam khoom. Cov xov xwm kub thiab txias los ntawm cov hluav taws kub uas nyob ib sab hloov phaj ntws los ntawm lawv cov kev sib txuas, qhov nruab nrab los ntawm ib lub phaj nyias nyias rau cov cua sov hloov, yog li lub zog txuag, siab kub hloov coefficient, kev nyab xeeb thiab txhim khu kev qha, compact qauv, me me, occupies ib cheeb tsam. ntawm tsawg, hloov tau yooj yim ua ke, yooj yim kho thiab tswj.
Phaj heat exchanger feem ntau muab faib ua: dej - dej pauv thiab chav - dej pauv hauv ob txoj kev. Dej - dej pauv hom kub thiab txias nruab nrab yog dej, thiab dej kub thiab dej txias qhov sib txawv tsis loj, tej zaum ntawm 70 ~ 90 degree, ob sab ntawm qhov scaling qhov xwm txheej yog qhov zoo ib yam; chav - dej pauv hom ntawm kub nruab nrab rau dej vapor, feem ntau tsis yooj yim rau scale, txias nruab nrab rau dej, kub txog li 90 degree, yooj yim rau scale. Cov nplai tuaj yeem muab faib ua nplai thiab av, tshwj xeeb tshaj yog raws li nplai. Cov nplai feem ntau yog yaj hauv dej los ntawm thermal decomposition ntawm ntau yam ntsev solubility txo thiab crystallization ntawm deposits nyob rau hauv lub tshav kub hloov piece, feem ntau yog carbonate, phosphate, sulfate thiab silicate, hom no scale crystallization ntom, kuj nyuaj, nyuaj rau tshem tawm; av feem ntau yog ua los ntawm cov khoom zoo ntawm av nkos, xuab zeb, hmoov av, insoluble ntsev ntawm av nkos, colloidal hydroxide, khib nyiab khib nyiab, corrosion khoom, roj, tshwj xeeb tshaj yog cov kab mob thiab algae thiab lawv viscous lub cev secretion thiab lwm yam khoom, qhov scale ntim yog loj, xoob thiab mos kev ntxhib los mos, yooj yim rau tshem tawm.
