Solvent rov qab tshuab yog cov khoom siv txuag hluav taws xob thiab txuag hluav taws xob. Nws txoj haujlwm tseem ceeb yog ua kom sov cov kuab tshuaj, hloov mus rau hauv cov roj, tom qab txias kom ua tiav cov kuab tshuaj sib cais, rov qab los ntawm cov kuab tshuaj qub, kom ua tiav lub hom phiaj ntawm kev txuag cov kuab tshuaj thiab kev tiv thaiv ib puag ncig.
Lub tshuab hnyav rov qab yog tsim los ntawm peb qhov chaw. Thawj feem yog lub preheater, uas ua kom sov cov kuab tshuaj thiab hloov mus rau hauv lub xeev gaseous. Qhov thib ob yog lub condenser, uas cais cov kuab tshuaj thiab cov kuab tshuaj tom qab txias lub gaseous hnyav. Qhov thib peb yog qhov rov qab, qhov sib cais ntawm cov kuab tshuaj yuav rov qab tau, thiab thaum kawg ua tiav cov txiaj ntsig ntawm kev txuag nqi ntawm kev siv.
Cov txheej txheem ua haujlwm ntawm lub tshuab hnyav rov qab yuav tsis tsim cov pa khib nyiab thiab cov pa phem, thiab yuav tsis ua rau muaj kev puas tsuaj rau ib puag ncig, uas ua tau raws li cov kev xav tau ntawm cov neeg niaj hnub no rau kev tiv thaiv ib puag ncig thiab kev tsim kho kom ruaj khov. Ntxiv mus, lub tshuab hnyav rov qab tuaj yeem ua tiav qhov kev yeej-yeej nyob rau hauv cov nqe lus ntawm kev lag luam thiab ib puag ncig cov txiaj ntsig.
Los ntawm kev pom kev lag luam, lub tshuab hnyav rov qab tuaj yeem txo cov nqi tsim khoom lag luam zoo heev. Cov kuab tshuaj feem ntau tuaj yeem rov ua dua yam tsis tas yuav rov yuav dua txhua zaus. Nyob rau tib lub sijhawm, qhov zoo ntawm cov kuab tshuaj zoo dua qub tsis txawv ntawm cov kuab tshuaj tshiab. Yog li ntawd, kev siv cov tshuab hnyav rov qab tuaj yeem txo cov nqi lag luam ntawm cov lag luam.
Los ntawm qhov pom ntawm kev tiv thaiv ib puag ncig, lub tshuab hnyav rov qab tuaj yeem tswj tau cov emission ntawm cov khoom tsis zoo, tuaj yeem zam kev ua paug rau ib puag ncig, thiaj li tiv thaiv ib puag ncig ecological. Tsis tas li ntawd, kev siv cov kuab tshuaj rov ua dua tuaj yeem txo qhov kev siv cov khoom siv ntuj tsim thiab txo qhov siab ntawm ib puag ncig.
Lub tshuab hnyav rov qab yog cov khoom siv tau zoo, ib puag ncig zoo thiab txuag hluav taws xob rov ua dua tshiab. Nws tuaj yeem pab cov tuam txhab txo qis cov nqi tsim khoom, tiv thaiv ib puag ncig thiab cov peev txheej ntuj, thiab yog ib qho khoom siv tiv thaiv ib puag ncig uas tsis tseem ceeb hauv cov txheej txheem tshuaj niaj hnub no.
