Yuav Ua Li Cas Tiv Thaiv Crystallization hauv Lithium Bromide Absorption Chiller?
Ntxiv rau kev siv lub raj U-shaped ua ib qho khoom siv siv lead ua tsis zoo, qee yam kev tswj hwm sab hauv yuav tsum tau teeb tsa hauv lub lithium bromide absorption tub yees kom tiv thaiv qhov tshwm sim ntawm crystallization.
(1) Txhim kho qhov kub thiab txias ntawm cov kav dej sib xyaw ua ke ntawm qhov hluav taws xob ntawm lub tshuab hluav taws xob. Thaum qhov kub thiab txias ntawm cov tshuaj concentrated yog siab dua tus nqi muab (qhov kub thiab txias nyob ntawm tus qauv tsim ntawm lub tub yees), qhov kub thiab txias relay yuav ua, tua lossis tua cov cua sov chav, thiab teeb lub tswb kom tiv thaiv qhov tshwm sim ntawm crystallization xwm txheej. Lub tswb ceeb toom ua rau tus neeg teb xov tooj nrhiav thiab tshem tawm qhov ua rau crystallization nyob rau lub sijhawm.
(2) Lub tshuab ua kua theem tswj tau muab tso rau hauv lub evaporator kua hnab phuam. Thaum cov kua theem ntawm cov dej txias tshaj tus nqi muab, cov kua theem tswj yuav ua rau qhib lub solenoid valve ntsia rau ntawm lub tub yees dej tub yees bypass, kom cov refrigerant dej nkag mus rau hauv lub absorber los ntawm lub evaporator kua sac bypass, txo. lub desalinated lithium Cov concentration ntawm cov tshuaj tiv thaiv crystallization vim lub siab concentration ntawm cov tshuaj. Thaum tus tswj qib ua kua ua haujlwm, lub tswb raug tso tawm, kom tus neeg teb xov tooj tuaj yeem daws teeb meem hauv lub sijhawm.
(3) Cov dej txias yuav raug txiav tawm lossis cov dej ntws tsawg dhau los tiv thaiv lub cuab yeej. Thaum lub twj tso kua dej txias tsis ua haujlwm, lossis qhov ntim dej txias tau txo qis vim yog lwm yam laj thawj, cov nyhuv nqus ntawm lub nqus dej tsis muaj zog heev, uas yuav ua rau cov concentration ntawm cov tshuaj ntawm qhov hluav taws xob ntawm lub tshuab hluav taws xob siab dhau thiab crystallize. . Txog rau qhov kawg no, lub siab (los yog qhov sib txawv siab) relay yog ntsia rau ntawm cov kav dej txias ntawm lub absorber. Thaum cov dej txias txias (los yog qhov sib txawv ntawm qhov sib txawv) qis dua tus nqi muab, lub relay yuav ua kom tua hluav taws kub thiab tawm lub tswb, kom tus neeg teb xov tooj tuaj yeem tshawb pom lub sijhawm. thiab kev daws teeb meem.
(4) Anti-crystalization ntaus ntawv thaum nres tsheb. Thaum lub tub yees cia li nres, vim hais tias cov concentration ntawm cov tshuaj nyob rau hauv lub generator yog kuj siab, yog hais tias nws tsis yog tov nrog dilute tov nyob rau hauv lub absorber, nws yuav crystallize vim kub poob tom qab nres. Cov khoom siv los tiv thaiv crystallization thaum lub sijhawm kaw tuaj yeem siv qhov ncua sij hawm los tswj cov twj tso kua mis thiab lub twj tso kua mis evaporator, kom ob lub twj tso kua mis txuas ntxiv mus rau lub sijhawm (10-15} feeb) tom qab lub qhov cub valve kaw, yog li ntawd cov tshuaj diluted ntawm lub absorber thiab cov concentrated tov ntawm lub tshuab hluav taws xob yog tag nrho tov thiab cov refrigerant vapor ntawm lub evaporator yog absorbed tag nrho. Nyob rau hauv txoj kev no, cov kev daws teeb meem nyob rau hauv txhua feem ntawm lub cev yog tov thiab diluted, uas tuaj yeem tiv thaiv crystallization tshwm sim vim qhov kub thiab txias tom qab kaw. Tsis tas li ntawd, qhov kub thiab txias relay ntsia rau ntawm lub qhov hluav taws xob cov yeeb nkab ntawm lub tshuab hluav taws xob kuj tuaj yeem ua rau cov twj tso kua mis thiab cov evaporator twj tso kua mis txuas ntxiv mus rau lub sijhawm tom qab lub tub yees raug tso tseg, kom txog rau thaum qhov kub ntawm cov tshuaj tov sib xyaw yog qis dua li qhov teev tseg. tus nqi.
