Tseem ceeb ntawm lim daim ntawv nyob rau hauv lim

Raws li ib tug zoo pom nruab nrab, lim daim ntawv tau lug siv nyob rau hauv ntau yam teb. Raws li cov hom fibers tias ua li tus lim daim ntawv, qhov kev kawm thiab kev siv ntawm lub lim daim ntawv no kuj sib txawv. Nws yuav siv tau rau ntau lim daim ntawv rau general zaus, iav fiber lim daim ntawv rau kub, thiab polypropylene lim daim ntawv rau ultra-huv.81084050021 6

Tus qauv ntawm lim daim ntawv yog ib tug labyrinth qauv tsim ntawm fibers thiab raws, uas ua ke nrog rau lub cev rog txuam nrog cov kua tshwm sim tawm lub filtering muaj nuj nqi ntawm lim daim ntawv. Lub pom mechanism yog raws li nram no:

1. Direct capture los yog interception

Nyob rau hauv tus txheej txheem no, ib txhia neeg yuam ntseeg tau hais tias nws tsuas yog tib qhov zoo tshaj txoj kev pom, thiab hais tias cov av ib qhov me me yog sim nyob rau hauv lub inflow nto los yog labyrinth xwb vim hais tias lawv yog loj tshaj lub aperture. Nyob rau hauv qhov tseeb, muaj yog:

2. Adsorption

Thaum lub lim kua kis los ntawm tus labyrinth, ib txhia hais yog adsorbed mus rau lub lim daim ntawv nyob rau hauv qhov kev txiav txim ntawm electrostatic attraction, txawm hais tias lub cheeb ntawm ib co hais yog npaum li cas me dua cov aperture. Yog li ntawd, ib txhia lim ntaub ntawv yog qhia tshwj xeeb uas ua nrog static hluav taws xob thaum lub sij hawm tsim txoj kev.

3. Hit thiab lub caij nplooj zeeg

Nyob rau hauv tus txheej txheem no, vim txoj kev sib raug ntawm tus nqi ndlwg, tus hais muaj cuab ncaj qha rau ntawm qhov chaw ntawm lub taub lim daim ntawv fiber es nyob rau hauv lub qhov hws ntawm lub taub lim daim ntawv, thiab cov adsorptive quab yuam thiab kua txaus dag zog yuam yog khaws cia nyob rau hauv nws, yog li thaiv cov hlab ib co me hais.

4. Pom thiab agglomeration

Nrog tus nruam txuam nrog ntawm av hais rau ntawm qhov chaw uas lim daim ntawv, nws cov ntaub ntawv ib lim txheej nws tus kheej, uas cuab me me hais nyob rau hauv lub pores ntawm loj hais. Nrog lub nce ntawm hais, cov kuj tsub kom tsis tu ncua, kom txog rau thaum thaum kawg kiag sim los yog mus txog lub differential siab.IMG_4735

Zus tau tej cov lim daim ntawv yooj yim heev. Nws yog cia li hais tias ib tug ntau yam ntawm fibers yog soaked nyob rau hauv dej-raws li binders mus disperse rau lawv kiag li, thiab ces tsim ib tug nruj nreem sib raug zoo kev twb kev txuas ntawv yob nyob rau txhob lo lo ntxhuav screen. Los ntawm kom qhuav, ntsw thiab kom qhuav, lub xam av noo theem yog tiav. Tab sis nyob rau hauv qhov tseeb, zus tau tej cov npaum lim daim ntawv, kom lub kev kawm ntawv tib ntawm batch thiab batch, yob thiab yob, txawm ntawm xyoo thiab xyoo, yuav yuav tsum tau nws hnyav, porosity, permeability, lub zog thiab lwm yam kev hloov nyob rau hauv ib tug nqaim ntau yam.

Lub lim cov ntaub ntawv uas nyob rau hauv lub lim yuav tsum tiv thaiv kom txhob lub lim system los yog puas los ntawm teeb meem hais, thiab nyob rau tib lub sij hawm tso cai rau txaus kua rau kis tau los ntawm, thiaj li kom tsis txhob cavitation nyob rau hauv lub twj tso kua mis, ua hauj lwm lub tog raj kheej thiab combustion chamber. Nyob rau hauv kev tshawb xav, ib tug zoo meej lim yuav tsum tshem tawm 100% ntawm cov kab mob hais thiab muab raws huab cua permeability. Tab sis nyob rau hauv qhov tseeb, qhov no yog tsis yooj yim sua.

Tus tsim ntawm lim daim ntawv yuav tsum ua txhua yam kom sib npaug rau ntau yam kev qhia nyob rau hauv thiaj li yuav zoo tiv thaiv cov system yuav tsum tau lim. Roj cov ntxaij lim dej muaj ntau dua uas yuav tsum tau rau lim daim ntawv tshaj cua ntxaij lim dej, mas vim hais tias cov concentration ntawm cov roj hloov correspondingly nyob rau hauv drastic kub hloov, uas yuav cuam tshuam rau pom txaus ntawm cov roj.
