Kev Kuaj Mob thiab Tso Pa Thaum lub caij cov tshuaj lom neeg siv, ntau yam tsis kaj siab, corrosive, lom lossis roj heev feem ntau tsim muaj. Yog tias cov teeb meem no tsis raug tshem tawm ntawm sab nraum zoov, nws yuav ua rau cov pa phem sab hauv, cuam tshuam rau kev noj qab nyob zoo thiab kev nyab xeeb ntawm cov neeg ua hauj lwm sim; cuam tshuam qhov tseeb thiab kev pab cuam lub neej ntawm cov cuab yeej siv, yog li ntawd, qhov chaw kuaj ntshav yog ib qho tseem ceeb ntawm cov qauv tsim. Txhawm rau cov neeg ua haujlwm hauv tsev neeg ua pa lossis nqus pa nqus pa, qaug tshuaj lossis tshuaj lom thiab tej yam kab mob, yuav tsum muaj qhov cua ntawm qhov kev kuaj kom zoo. Tiv thaiv kom qee lub vapors, gases thiab particulates (haus luam yeeb, soot, plua plav thiab aerosols) los ntawm kev nqus tau pa, cov pa paug yuav tsum tau muab tshem tawm los ntawm kev siv lub foob hood, lub tsho thiab cov pa qis.

Qhov chaw tso tawm hauv zos yog tawm tam sim ntawd tom qab lub sijhawm ntawm cov teeb meem tshuaj. Txoj kev no tuaj yeem tshem tawm ntau ntau cov khoom uas muaj teeb meem nrog cua txias tsawg, thiab lub zog tau txais kev cawmdim thiab qhov tshwm sim zoo. Nws yog ib txoj kev ua tau zoo thiab nyiaj txiag los txhim kho cov kev mob uas twb muaj lawm, thiab tej zaum nws yog qhov zoo tshaj los kho qhov tshiab kuaj qhov cua ntawm kev siv. Rau qee qhov kev sim, yuav tsum tsis txhob siv lub zos qaug siv, lossis hauv zos cov pa yuav tsum tsis txhob muaj qhov yuav tsum tau cua ntawm qhov cua.
Lub hlais hood yog qhov chaw siv lub tshuab pa feem ntau siv rau hauv kev sim, thiab nws qhov kev ua tau zoo nyob ntawm kev ceev ntawm huab cua zog los ntawm lub fume hood.Factors cuam tshuam rau pem hauv ntej ceev thiab cua zog yog eddy currents, txee hauv puab cov duab, tho khoom siv hluav taws xob, mechanical kev txiav txim siab, qhov chaw tawm qhov cua, thiab kev sib tw. Tsis tas li, nws muaj feem xyuam rau nws rab peev xwm los tua hluav taws, txhuam qhov yooj yim, yooj yim ntxuav, thiab muaj peev xwm sau qee yam kab mob ua ntej lawv nkag mus rau hauv qhov system. Nws feem ntau ntseeg hais tias lub fume hoods nyob rau hauv qhov kev kuaj yuav tsum ua kom haum cov kua thiab cov roj cua, thiab cov khoom siv hauv cov khoom yuav tsum muaj li ob peb feeb ntawm cov hluav taws tsis ua hauj lwm kom lub fum hood tsis zoo thiab raws caij nyoog.
Lub tshuab cua ntawm lub fume hood tau muab faib ua ob hom: centralized thiab decentralized. Qhov nruab nrab yog lub zog ntawm ib los yog ob lub plag tsev ntawm fume hoods, los yog tag nrho cov kev sim ntawm lub tsev sib faib ua ob lub. Nws yog cov cuab yeej ua rau lub tshuab tsis tshua muaj zog, tsawg dua cov cuab yeej cuab tam, thiab nce me ntsis ntawm cov hle qhov fum, nrog rau cov kev hloov hauv qhov chaw, muaj qee qhov kev hloov ntawm kev yoog. Txawm li cas los xij, vim yog lub cev loj, cov cua ntim tsis yooj yim rau seem. Txawm hais tias txhua lub fume hood yog nruab nrog ib qhov kev tswj tuav, nws tsis yooj yim siv thiab nws tsis yog yooj yim mus cuag cov kev npaj siv. Yog tias cov kab ciav raug puas lawm thiab yuav tsum tau kho, tag nrho lub fum hood yuav siv tsis tau. Vim li no, cov chaw sim siv lub tshuab ua haujlwm hauv nruab nrab tau hloov nrog cov kev ua haujlwm ncaj ncees.
Decentralized yog kev koom ua ke ntawm ib lub fume hood los yog ob peb lub tsho dav hlau nyob rau hauv tib chav tsev mus rau hauv ib qhov system. Nws tus cwj pwm yog: tus kiv cua yuav tsum nres thiab ua raws li kev ua hauj lwm xav tau ntawm lub fume hood, kev cuam tshuam kev sib txuam, yooj yim mus cuag cov nyhuv yam, thiab ntau lub zog txuag dua centralized, vim hais tias centralized system, ntev li ntev ib fume Hood yog siv, Pib lub kiv cua loj. Vim tias qhov loj me me ntawm lub cev, qhov cua ntim tsawg me thiab qhov tsis muaj zog. Yog li ntawd, huab cua ntim thiab cua siab ntawm tus kiv cua tsis loj, thiab lub suab nrov thiab kev vibration yog correspondingly me me. Lwm qhov tshwj xeeb ntawm hom kev ncaj ncees yog tias nws yog ib qho yooj yim los kho cov teeb meem roj cua uas muaj kev txawv txav. Qhov tsis zoo yog tias cov neeg siv lub tshuab ua pa loj yog qhov loj thiab qhov system muaj ntau. Yog tias lub tshuab ua pa khov kho nyob hauv chav lub tshuab ua pa, qhov peev yuav nce. Yog tias lub tshuab ua pa cais thiab muab ntsia rau ntawm qhov chaw, txawm tias cov peev ntawm lub tshuab ua pa nce siab, qhov peev ntawm qhov nyiaj tau txais txuag tau, thiab thaum kawg tag nrho cov peev tag nrho tsis tas nce ntxiv lawm. Thaum faib qhov system, yog tias muaj ntau tshaj li ob lub tsho dav hlau nyob hauv ib chav, nws yuav tsum muab faib ua ib qho kom tsis txhob muaj ib lub fume hood raug siv, thiab lwm lub tsho dav hlau rov qab mus rau sab nraud, kom nyob hauv tsev yog polluted. Ib yam li ntawd, ntxiv rau ib qho kev tso tawm hauv chav tsev, nws tsis tsim nyog rau nruab rau lwm cov pa tua kab.
Lub tshuab cua ntawm lub raj cua feem ntau yog ntsia rau ntawm lub ru tsev los yog hauv chav hauv chav nruab nrab ntawm lub qhov cua, kom lub cheeb tsam uas tsis muaj chaw nyob tsis muaj chaw, thiab cov pa taws hauv sab hauv yog muaj kev kub ntxhov kom tsis txhob muaj teeb meem tshuaj los ntawm corrosion or damage of tus kav raj xa dej, thiab vim tias cov raj xa dej tsis nruj thiab nkag mus rau hauv chav tsev, ntxiv rau, lub tshuab ua hluav taws xob ntsia nruab nrab ntawm lub ru tsev los yog hauv chav hauv chav nruab nrab ntawm sab saum toj, uas yog yooj yim rau kev soj ntsuam thiab yooj yim tshem tawm los yog txo qhov kev kub ntxhov.
