Thov nco ntsoov:

(1) EPDM gaskets yuav tsum tsis txhob sib cuag nrog cov kuab tshuaj tsw qab tshaj li ib nrab teev.

(2) Sab nraub qaum ntawm lub phaj tsis tuaj yeem kov hauv av ncaj qha thaum ntxuav.

(3) Tom qab ntxuav dej, xyuas kom zoo zoo ntawm daim phiaj thiab cov gaskets thiab tsis muaj residua xws li cov khoom thiab cov fibers sab laug rau ntawm lub phaj. Lub tev tawm thiab puas gasket yuav tsum tau glued los yog hloov.

(4) Thaum ua cov tshuab ntxuav, cov txhuam hlau tsis raug tso cai siv kom tsis txhob khawb phaj thiab gasket.

(5) Thaum ntxuav nrog rab phom dej siab, lub phaj nruj lossis lub phaj ntxiv yuav tsum tau siv los txhawb lub phaj rov qab (phaj no yuav tsum tau hu rau tag nrho nrog cov phaj kub sib hloov) kom tsis txhob deformation, qhov deb ntawm nozzle thiab pauv phaj yuav tsum tsis pub tsawg tshaj 200 hli, qhov max. kev txhaj tshuaj siab tsis ntau tshaj 8Mpa; Lub caij no, kev sau cov dej yuav tsum tau ua tib zoo saib yog siv rab phom dej siab kom tsis txhob muaj kab mob ntawm qhov chaw thiab lwm yam khoom siv.

2  Tshuaj ntxuav

Rau qhov zoo tib yam fouling, raws li nws cov khoom, tus neeg sawv cev alkali nrog huab hwm coj concentration tsawg dua lossis sib npaug li 4% lossis acid tus neeg sawv cev nrog cov concentration tsawg dua lossis sib npaug li 4% tuaj yeem siv los ntxuav, cov txheej txheem ntxuav yog:

(1) Ntxuav kub: 40 ~ 60 ℃.

(2) Rov qab yaug yam tsis muaj kev cuam tshuam ntawm cov khoom siv.

a) Txuas cov yeeb nkab ntawm cov xov xwm inlet thiab qhov hluav taws xob kav ua ntej;

b) Txuas cov khoom siv nrog "tus kws kho tsheb tu";

c) Tso cov tshuaj ntxuav rau hauv cov khoom siv nyob rau hauv qhov sib txawv raws li cov khoom siv niaj hnub ntws;

d) Circulate ntxuav kua 10 ~ 15 feeb ntawm cov xov xwm ntws ntawm 0.1 ~ 0.15m / s;

e) Thaum kawg rov ua dua 5 ~ 10 feeb nrog dej huv. Cov ntsiab lus chloride hauv dej huv yuav tsum tsawg dua 25ppm.

Thov nco ntsoov:

(1) Yog tias siv txoj kev ntxuav no, qhov kev sib txuas ntawm cov khoom seem yuav tsum tau nyob ua ntej sib dhos kom cov dej ntxuav tau ntws tawm kom zoo.

(2) Cov dej huv yuav tsum tau siv los ntxuav lub tshuab hluav taws xob yog tias cov dej ntws rov qab ua tiav.

(3) Tus neeg saib xyuas tshwj xeeb yuav tsum tau siv los ntxuav cov av tshwj xeeb raws li cov xwm txheej tshwj xeeb.

(4) Cov txheej txheem tu tshuab thiab tshuaj lom neeg tuaj yeem siv ua ke nrog ib leeg.

(5) Txawm hais tias txoj kev twg yog siv, cov hydrochloric acid tsis raug tso cai los ntxuav lub phaj hlau stainless. Cov dej ntawm ntau tshaj 25 ppm chlorion cov ntsiab lus yuav tsis raug siv rau kev npaj cov kua dej los yog dej yaug stainless hlau phaj.
