1. Taw qhia ntawm phaj kub exchanger hauv kev lag luam tshuaj
Kev lag luam tshuaj muaj xws li: kev lag luam bromine, petrochemical kev lag luam, silicate kev lag luam, zaub mov thiab dej haus kev lag luam, ntawv kev lag luam, tshuaj lag luam, chlor-alkali kev lag luam, sulfuric acid kev lag luam, inorganic ntsev kev lag luam, chiv kev lag luam, textile kev lag luam, yas kev lag luam, thiab lwm yam., thiab tag nrho kev lag luam complements ib leeg. Nws tsis yog tsuas yog tsim cov khoom tsim nyog rau tib neeg lub neej, tab sis kuj yog tus xa khoom ntawm cov khoom siv raw thiab cov khoom siv rau lwm cov lag luam, thiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev lag luam.
2. Lub luag haujlwm ntawm lub phaj kub exchanger ua haujlwm li cas hauv ntau yam kev lag luam tshuaj?
1. Kev lag luam sulfuric acid
Lwm lub npe rau lub phaj kub exchanger: txias. Muaj feem ntau purification acid coolers, qhuav acid coolers, ib-absorption acid coolers, thiab ob-absorption acid coolers nyob rau hauv lub smelting acid ntau lawm txheej txheem. Ntawm lawv, lub purified acid txias yog tsuas yog siv los txo qhov kub ntawm dilute acid, thiab qhov nruab nrab yog feem ntau dilute sulfuric acid thiab dej nrog ib tug concentration ntawm txog 5 mus rau 20℅. Qhov nruab nrab ntawm cov kua qaub qhuav txias yog sulfuric acid thiab dej nrog ib qho concentration ntawm 93-96℅. Thawj thiab theem nrab acid txias tshaj tawm yog cov concentrated sulfuric acid thiab dej nrog ib tug concentration ntawm txog 98.5℅.
2. Kev lag luam Caustic soda
1) Cov txheej txheem brine ib zaug:
Cov ntsev nyoos nkag mus rau hauv lub tank ntsev, thiab lub teeb brine los ntawm cov txheej txheem electrolysis, cov dej rov qab los ntawm cov cuab yeej thiab cov dej ua kom zoo yog siv los ua kom cov dej saturated crude brine.
2) Electrolysis txheej txheem:
Cov txheej txheem electrolysis muaj peb ntu: theem nrab brine refining, electrolysis thiab dilute brine dechlorination.
3) evaporation thiab khoom alkali txheej txheem:
Tom qab 32 feem pua NaOH los ntawm electrolysis
4) Cov txheej txheem kho chlorine:
Cov roj chlorine ntub dej los ntawm cov txheej txheem electrolysis yog thawj zaug ntxuav los ntawm chlorine gas scrubber, thiab tom qab ntawd nkag mus rau hauv cov roj chlorine cua txias (lwm lub npe ntawm lub phaj kub exchanger) kom txias nrog dej txias, thiab tom qab ntawd xa mus rau lub tsev ntim khoom los ntawm cov dej pos separator tiv tauj nrog sulfuric acid nyob rau hauv countercurrent rau zaum ob. Nyob rau hauv ib kauj ruam lub cev qhuav dej, cov chlorine roj los ntawm cov packed ntauwd raug xa mus rau lub npuas ntauwd ua countercurrent tiv tauj nrog concentrated sulfuric acid kom lub cev qhuav dej ntxiv, thiab ces cov kua qaub pos yog sau los ntawm cov kua qaub pos nphuab, thiab ces compressed thiab pressurized los ntawm lub chlorine compressor thiab xa mus rau cov neeg siv tshuaj chlorine.
5) Kev kho cov roj pov tseg:
Cov roj chlorine los ntawm kev kaw thiab kev sib tsoo lub xeev ntawm lub cuab yeej yog thawj zaug absorbed nyob rau hauv lub absorption ntauwd nrog lub nqus lye los ntawm lub circulation tank, thiab tus Tsov tus tw gas tom qab absorbing cov tshuaj tiv thaiv nkag mus rau hauv lub Tail gas pej thuam rau ntxiv nqus nrog lye, thiab lub nqus. kua yog tsim los ua 10 feem pua NaClO khoom. Xa cov khoom siv acetylene. Peb lub tuam txhab kuj muaj lub tshuab hluav taws xob flue, uas tuaj yeem siv tau ntawm no.
6) Cov txheej txheem kho hydrogen:
Cov dej ntub dej los ntawm cov txheej txheem electrolysis nkag mus rau hauv qis ntawm hydrogen scrubbing ntauwd thiab ncaj qha txias thiab ntxuav nrog cov kua circulating sprayed nyob rau hauv lub pej thuam. Lub alkali pos huab thiab chav condensate uas muaj nyob rau hauv hydrogen yog muab tshem tawm los ntawm cov circulating kua thiab ces xa mus rau hauv lub hydrogen compressor pressurized, thiab ces xa tawm ntawm ciam teb cheeb tsam los ntawm ob theem ntawm txias.
7) Hydrogen chloride synthesis thiab high-purity hydrochloric acid txheej txheem:
Chlorine thiab hydrogen yog combusted nyob rau hauv ib tug ob-hauv-ib graphite synthesis rauv los tsim hydrogen chloride gas. Cov roj hydrogen chloride generated yog txias los ntawm hydrogen chloride txias dej tank thiab hydrogen chloride cooler (lwm lub npe rau lub phaj kub exchanger), thiab ces ib nrab xa mus rau lub VCM ntaus ntawv raws li raw khoom los ntawm lub hydrogen chloride faib rooj, thiab ib feem. xa mus rau high-purity hydrochloric acid nqus system. 3. Petroleum refining Plate heat exchanger yog ib qho khoom siv tseem ceeb hauv kev lag luam petrochemical. Raws li kev txheeb cais, nyob rau hauv cov roj refineries, qhov kub exchanger no suav txog li 40 feem pua ntawm tag nrho cov tshuab. Nws tsis yog tsuas yog lub ntsiab cua kub exchanger nyob rau hauv cov txheej txheem, tab sis kuj yog lub ntsiab txhais tau tias rau cov lag luam kom txo tau lub zog noj thiab nqi. Yog li ntawd, cov txheej txheem ntawm phaj kub exchangers yog ib qho ntawm cov cim tseem ceeb ntawm qib siab ntawm refineries. Cov phaj kub exchangers ua los ntawm peb cov phaj kub exchanger manufacturers yog haum rau cov kev xav tau kev pab ntawm petrochemical kev lag luam. Tsis tas li ntawd, cov cua kub exchanger tsim thiab tsim los ntawm peb lub tuam txhab ua lub luag haujlwm tseem ceeb hauv kev lag luam petrochemical. Siv cov cua tsis muaj zog ua qhov cua txias nruab nrab, piv rau cov dej txias (dej phaj kub exchanger), nws yog ib qho tseem ceeb ntsuab txuag hluav taws xob txuag hluav taws xob, thiab nws kuj zam qhov teeb meem dej paug ntau dua.
4. Kev lag luam cawv
Kev lag luam cawv: Raws li lub ntiaj teb cov peev txheej roj av tau poob qis ib xyoos ib zaug thiab tsis tuaj yeem rov ua dua tshiab, cov roj cawv tau dhau los ua ib qho ntawm cov khoom siv hluav taws xob zoo dua. Nws siv hom qoob mog, pob kws, sorghum, qos yaj ywm los yog cog fiber ntau li raw cov ntaub ntawv rau ntau lawm thiab hu ua ntsuab zog.
Lub detachable wide-channel phaj kub exchanger, raws li ib tug high-efficiency tshav kub exchanger uas combines qhov zoo ntawm phaj kub exchangers thiab kauv phaj kub exchangers, paub txog cov organic ua ke ntawm npaum tshav kub hloov thiab yooj yim txij nkawm. Nws tau raug siv hauv kev lag luam cawv. Cov txheej txheem mash txias.
Cim npe nrov: phaj kub exchanger nyob rau hauv chemical kev lag luam, Tuam Tshoj, lwm tus neeg, manufacturers, pheej yig, pricelist, luv nqi, kev muag khoom
