Nyob zoo sawv daws! Niaj hnub no, peb yuav tham txog kev phom sij ntawm impurities nyob rau hauv dej ntawm phaj kub exchanger Kuv ntseeg hais tias muaj coob tus neeg tsis yog ib tug neeg txawv ntawm cov cua sov exchangers, tab sis koj puas paub dab tsi txaus ntshai ntawm impurities nyob rau hauv cov dej ntawm tshav kub exchangers? Ntawm no cia kuv coj koj mus nrhiav.
Ua ntej ntawm tag nrho cov, peb yuav tsum to taub lub luag hauj lwm ntawm lub tshav kub exchanger. Thaum tshav kub kub exchanger yog ib qho tseem ceeb ntawm cov cua txias, cua sov thiab lwm yam khoom siv, nws yog los ntawm kev hloov cov cua sov, kom ua tiav cov kev sib pauv ntawm cov cua sov thiab txias. Thiab phaj kub exchanger yog dav siv nyob rau hauv ntau zaus vim nws high efficiency thiab compactness. Txawm li cas los xij, muaj cov impurities nyob rau hauv dej ua rau cov phaj kub exchangers ntsib ntau yam teeb meem.
Dej impurities nyob rau hauv "peb kev txhaum"
1. Calcium ntsev: Calcium ntsev yog cov khoom tseem ceeb uas ua rau lub tshav kub exchanger scaling. Scale tsis tsuas yog txo qhov ua tau zoo ntawm kev sib pauv cua sov, tab sis kuj tuaj yeem ua rau cov khoom puas tsuaj. Tshwj xeeb tshaj yog CaSO4, nws yog ib qho nyuaj, crystalline nplua scale, yooj yim rau tsim xoob slag rau saum npoo ntawm lub tshav kub exchanger, cuam tshuam rau lub lag luam ntawm cov khoom.
2. magnesium ntsev: magnesium ntsev yog thermally decomposed nyob rau hauv dej, tsim Mg (OH) 2 nag lossis daus thiab tsim slag nplai. Tsis tas li ntawd, MgCl2 thiab MgSO4 yaj hauv dej kuj yuav ua rau acidic corrosion ntawm phab ntsa hlau. 3.
3. Sodium ntsev: Txawm hais tias NaCl tsis tsim cov nplai, tab sis nws yuav ua kom lub zog corrosion ntawm phab ntsa hlau; Na2SO4 cov ntsiab lus siab dhau lawm, nws yuav tsim ntsev tom qab evaporator, uas cuam tshuam rau kev ua haujlwm nyab xeeb; NaHCO3 decomposes nyob rau hauv qhov kev txiav txim ntawm qhov kub thiab txias, uas ua rau kev puas tsuaj ntawm hlau nplej.
Tsis tas li ntawd, kev phom sij ntawm cov pa oxygen yaj yuav tsum tsis txhob ignored. Oxygen yog lub ntsiab ua rau kub exchanger corrosion, nws ua rau cov hlau nto Fe (OH) 3 nag lossis daus, ua kom cov txheej txheem corrosion.
Cov impurities muaj nyob rau hauv lub xeev colloidal
1. Iron compounds: Hlau nplai cuam tshuam rau kev sib pauv cua sov thiab ua rau cov dej daj.
2. Cov kab mob microorganisms: cov kab mob kis tau ntau hauv cov dej txias thiab zoo li thaiv cov phaj raws, ua rau hlau corrosion.
3. sludge: hmoov av nyob rau hauv cov huab cua thiab tshem tawm cov teeb meem nyob rau hauv cov dej ntxiv yuav muab tso rau hauv lub tshav kub exchanger, cuam tshuam rau lub lag luam ntawm cov khoom.
4. Cov nplai nplaum nplaum: cov microbial secretions thiab dej sediment, cov khoom siv corrosion, cov kab mob fungal thiab algal khib nyiab sib txuas, txuas rau cov phab ntsa ntawm cov cua kub exchanger, ua rau corrosion.
