Qee qhov kev paub hauv kev siv multi - hom phiaj rauv

The controlled atmosphere is a nitrogen-methanol atmosphere, that is, 40% nitrogen and 60% methanol are sent into the furnace, and the obtained composition is basically the same as the traditional endothermic atmosphere, that is, 20% C0 + 40% H2 + 40% N2, and the enrichment gas is propane. Qhov zoo ntawm cov cua no yog:

(1) Cov lus sib xyaw yog qhov ruaj khov, tshwj xeeb tshaj yog cov piv ntawm lub siab ntawm C0 thiab H2 ntsig txog cov pa roj carbon monomanet tuaj yeem khaws tau yooj yim thiab yooj yim dua.

(2) nyob rau hauv lub xyoo ntawm cov tswj cua sov kev kho cua sov, nws yog tus kawm tau ob qho tib si hauv cov txheej txheem thiab kev tswj hwm.

(3) Cov roj txheem hluav taws xob yog tshem tawm, qhov pib pib, thiab tsis tas yuav muaj kev npaj preheater.

(4) Nws muaj kev nyab xeeb thiab txhim khu kev qha, thiab nitrogen tuaj yeem qhia tau thaum muaj xwm txheej ceev los tiv thaiv kev sib tsoo.

(5) Kev kho cua sov ua tau zoo dua qub. Piv nrog endothermic huab cua, tus nqi ntawm cov pa roj carbon yog tsawg dua, cov qoob loo qoob loo tsawg dua, thiab cov khoom ua haujlwm kho tau zoo dua.

Tsis muaj teeb meem twg mortened cua yog siv, lub cev yuav tsum tau lees. Qhov no tau txais txiaj ntsig zoo rau cov cuab yeej siv lub neej thiab qhov zoo. Peb cov kev xav tau rau nitrogen: purity ntau dua los yog sib npaug ntawm 99.5%, 02 tsawg dua lossis sib npaug nrog 0.5%, lwg me ntsis lossis sib npaug rau -40 degree; Yuav tsum muaj rau cov tshuaj tiv thaiv: Purity ntau dua lossis sib npaug ntawm 90%, s cov ntsiab lus<0.001%, impurities <0.3%～0.5%; requirements for methanol: purity ≥99.5%, water content <0.5%.

(1) Ua ntej qhib lub cub tawg, nws yog qhov tsim nyog los xyuas kom meej tias cov khoom siv ntawm ntau cov khoom siv, thiab ntau cov kav dej thiab cov kav dej tau xau {1} pub dawb. Yog tias cov hluav taws xob xa tawm tau pom tias tsis ua hauj lwm, lub cub tawg yuav tsis qhib.

(2) Thaum cov khoom lag luam ua haujlwm, cov khoom siv hluav taws xob ua haujlwm, cua sov, cua sov thiab cov kua nruab nrab. Yog tias muaj teeb meem tshwm sim, lawv yuav tsum tau hais txog raws sijhawm.

(3) Tsuas yog thaum lub cua sov sov yog siab dua 760℃tuaj yeem qhia rau hauv qhov cub lossis cov cua hauv qhov cub tawg, txwv tsis pub nws yuav ua rau tawg.

(4) Thaum lub cua sov sov nyob rau siab tshaj 150 Degree, yuav tsum tsis txhob cuam tshuam rau cov dej thiab roj kiv cua txias thiab cov roj txias yuav tsum tsis txhob muab cov xwm txheej.

(5) nyob rau hauv ib txwm muaj xwm txheej, ntau - lub hom phiaj rauv yuav tsum muaj kev ua haujlwm txuas ntxiv thiab nres li sai tau. Luv -}} kev kaw lus yam tsis muaj txias (800℃rwb thaiv tsev) kuj yog ib qho kev paub tseem ceeb kom cov khoom tsis muaj nqis.
