Dab tsi yog yam uas cuam tshuam rau kev pom kev ua haujlwm ntawm cov lim cua?

Cua lim lim efficiency nyob rau hauv lub procurement ntawm huab cua lim yog qhov tseem ceeb ntawm cov ntaub ntawv, pom efficiency cuam tshuam rau kev xaiv ntawm muas khoom thiab tom qab ntau lawm efficiency thiab ib puag ncig. Txij li thaum pom kev ua haujlwm tseem ceeb heev, dab tsi yog qhov cuam tshuam rau kev pom kev ua haujlwm ntawm cov lim cua? Nov yog plaub yam los tshuaj xyuas rau koj.
1. Lim hnab khoom:
Kev xaiv thiab siv cov khoom siv lim lim yog cov cuab yeej siv thev naus laus zis ntawm cov khoom siv hauv lub hnab ntim plua plav, uas ua lub luag haujlwm txiav txim siab hauv kev ua tau zoo ntawm kev ua haujlwm siab huab cua lim plua plav collector. Vim tias ib puag ncig ntawm txhua qhov chaw khaws cov plua plav, qhov xwm txheej, qhov kub thiab txias thiab kev xav tau ntawm kev kho cov plua plav tsis zoo ib yam, cov ntaub ntawv sib txawv yuav tsum raug xaiv rau cov xwm txheej sib txawv, thiab cov kev tiv thaiv kev tiv thaiv yuav tsum tau ua. Cov kev xav tau rau cov khoom siv lim lim muaj xws li cov kev ua haujlwm hauv qab no: cov khoom siv lim lim yog tsim rau qhov sib txawv ntawm qhov kub thiab txias, zoo stripping, yooj yim tu, zoo huab cua permeability, tsis muaj zog, siab filtration efficiency, siab zog, muaj peev xwm tiv taus siab zog tu, ntev kev pab cuam lub neej. , thiab tus nqi tsim nyog.
Thib ob, qhov cuam tshuam ntawm lim cua ceev:
Cov cua ceev ua rau muaj kev tiv thaiv, thiab cua ceev txo qhov tsis kam. Rau cov khoom loj uas tau tswj hwm los ntawm inertial motion, qhov nce ntawm cov cua ceev yuav ua rau cov inertia ntawm cov khoom thiab ua rau kom muaj kev cuam tshuam cov teeb meem, yog li qhov pom kev ua haujlwm yuav raug txhim kho. Txawm li cas los xij, thaum lub inertia loj, qhov rov qab los ntawm kev cuam tshuam rau cov khoom kuj nce. Yog tias lub zog van der Waals tsis tuaj yeem kov yeej qhov rov qab, cov khoom yuav khiav tawm. Yog li ntawd, lub lim efficiency ntawm cov khoom loj yuav raug txo kom tsawg thaum cua ceev yog qee zaum nce.
Rau cov khoom me me dominated los ntawm diffusion txav, qhov pom kev ua haujlwm nyob ntawm lub sijhawm khaws cia ntawm cov khoom hauv qhov nruab nrab pom. Yog tias lub sijhawm khaws cia yog luv luv (qhov cua ceev yog nce), qhov tshwm sim ntawm cov khoom cuam tshuam los ntawm kev cuam tshuam yog txo, thiab qhov pom kev ua haujlwm qis dua. Yog tias cov khoom muaj hluav taws xob zoo li qub, qhov pom kev zoo nyob ntawm lub sijhawm khaws cia ntawm huab cua ntws hauv cov khoom. Qhov qis dua qhov pom ceev, qhov siab dua qhov pom kev ua haujlwm, rau ob qho tib si loj thiab me me.
Cov khoom siv electrostatic yog rhiab heev rau lub lim cua ceev. Piv txwv li, thaum ntsuas ntawm 1 cm / s cua ceev, qhov transmittance ntawm 0.3 μm plua plav yog 0.01% (filtration efficiency 99.99%), thiab thaum pom ceev nce mus rau 5.3 cm / s, qhov transmittance yog ntsuas los ntawm 1.5% (filtration efficiency tsuas yog 98.5%), uas yog ob qhov kev txiav txim ntawm qhov sib txawv ntawm qhov sib txawv hauv kev xa tawm.
Thib peb, qhov cuam tshuam ntawm cov av noo:
Raws li ib txwm muaj, hloov cov av noo yuav tsis cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ntawm huab cua lim. Txawm li cas los xij, thaum huab cua noo siab heev, qhov nruab nrab pom tuaj yeem dew, qhov sib cuag ntawm cov khoom thiab qhov cuam tshuam muaj cov yeeb yaj kiab dej, qhov sib cuag ntawm ob qhov loj, lub zog sib txuas yog loj, thiab cov khoom loj yog tsis yooj yim rau rebound, yog li qhov pom kev ua haujlwm ntawm cov khoom loj tuaj yeem txhim kho.
Hauv kev muaj tiag, yog tias lub lim dej ntub dej los nqa dej, qhov kev ua tau zoo ntawm cov lim yuav raug hloov pauv ntau yam tsis paub tseeb. Piv txwv li, rau cov ntawv lim ua los ntawm cov nroj tsuag fiber ntau, yog tias cov dej tsis kam ntawm cov ntawv tsis zoo, cov dej ua rau cov ntawv muag muag, cov fiber ntau compresses, thiab cov kev tawm tsam ntawm cov lim yuav nce sai heev kom txog thaum lub lim raug thaiv. Piv txwv li, cov lim dej ua haujlwm siab nrog dej, plua plav yuav raug thauj los ntawm dej mus rau lee sab ntawm cov khoom, tom qab ziab, cov lim yuav dhau los ua cov plua plav generator.
Plaub, cua nkag
Cov pa xau ncaj qha cuam tshuam rau cov plua plav sau cov nyhuv thiab lub neej ntawm cov plua plav collector, thiab cov pa xau yuav tsum tau ua.<3%. Bag type dust collector is generally negative pressure operation, such as air leakage is easy to form a small circuit short circuit. Dust collection system processing air volume is not enough, forming positive pressure dust. Air leakage will also reduce the system temperature, easy to generate moisture paste bag, increase the dust collection resistance, reduce the filter effect of air filter equipment.
