Gasi kusefa ndiyo inodiwa tekinoroji muminda yeindasitiri, tsvakiridzo yesainzi uye hupenyu.Inogona kunyatsoparadzanisa uye kubvisa tsvina yakadai sechinhu chinonzi particulate matter, zvinhu zvinokuvadza uye microorganisms mugasi, nokudaro kuvandudza kuchena uye kuchena kwegesi.
Minda yekushandiswa kwekusefa gasi yakafara kwazvo, kusanganisira kucheneswa kwegasi mumaindasitiri, kuchenesa gasi rekurapa, kuchengetedzwa kwezvakatipoteredza marara gasi kurapwa, kemikari gasi guruva kubviswa, etc. Kuburikidza nekushandisa gasi kusefa zvigadzirwa, kuchena uye kuchena kwegasi kunogona kubudirira. yakavandudzwa, nharaunda uye hutano hwevanhu hunogona kuchengetedzwa, kushanda zvakanaka uye kugadzikana kwemidziyo inogona kuvandudzwa, hupenyu hwebasa remidziyo inogona kuwedzerwa, uye mari yekuchengetedza nekugadzirisa inogona kuderedzwa.
Kusefa kwegasi kunoreva kubviswa kwetsvina, zvidimbu, zvinhu zvinokuvadza, nezvimwewo mugasi nenzira dzepanyama kana dzemakemikari kuvandudza kuchena uye kuchena kwegasi.Kusefa gasi kunonyanya kushandisa mafirita, mafirita, uye mafirita skrini, uye anoona kupatsanurwa uye kusefa kwemagasi kuburikidza nemisimboti yekusevha, gravity sedimentation, inertial collision, electrostatic sedimentation, uye diffusion sedimentation.
Nheyo yekusefa gasi inonyanya kusanganisira kupatsanurwa, kuisa pfungwa uye kuomesa.Kuparadzaniswa kunoreva kupatsanurwa kwezvikamu uye zvinhu zvinokuvadza mugasi kubva mugasi;kusungirirwa kunoreva kuderedzwa kwehuwandu hwekusachena mugasi rakacheneswa, nekudaro kunatsiridza kuchena kwegasi;kuomesa zvinoreva kubviswa kwemwando nezvimwe zvinhu mugasi rakasefa.Kubviswa kwakashata kune gasi rakaoma
Kusefa kwegasi kunonyanya kuenderana nesefa yepakati, uye tsvina iri mugasi inopatsanurwa kuburikidza nemapores kana adsorption pane sefa yepakati.Iyo sefa yepakati inogona kuve mumhando dzakasiyana senge fiber, zvimedu, membranes, nezvimwewo, uye kusefa kwayo kunoenderana nezvinhu zvakaita sehukuru hwepore, chimiro, uye adsorption kuita kwepakati.Nheyo dzekuparadzanisa dzinonyanya kusanganisira kuongorora, giravhiti sedimentation, inertial kudhumhana, electrostatic sedimentation, diffusion sedimentation, nezvimwewo, uye misimboti yekuparadzanisa inosarudzwa zvichienderana nehukuru uye chimiro chezvimedu zvetsvina.
Panyaya yegesi, zvigadzirwa zvemasefa zvinonyanya kushandiswa mukubvisa guruva gasi, kucheneswa, kupatsanura uye zvimwe zviitiko.Semuenzaniso, muindasitiri yemakemikari, simba remagetsi, simbi uye mamwe maindasitiri, zvinodikanwa kubvisa zvinhu, magasi anokuvadza, utsi, nezvimwewo mumhepo yekuburitsa gasi kusangana nekuchengetedzwa kwezvakatipoteredza emission standard kana chinangwa chekudzokorora.Zvigadzirwa zvekusefa zvinoshandisa mhando dzakasiyana dzemasefa zvinhu, mabhegi ekusefa uye membrane zvinhu kuti uwane kusefa uye kucheneswa kwemagasi.
Mumashandisirwo anoshanda, zvigadzirwa zvekusefa zvinoda kusarudzwa zvinoenderana neyakasiyana gasi zvivakwa, kuyerera kwemazinga uye kusefa zvinodiwa.Semuenzaniso, kune magasi ane hunyoro hwepamusoro uye zvidimbu zvakawanda, zvinodikanwa kuti usarudze chinodzivirira uye chinopfeka-chinodzivirira sefa chinhu kana bhegi resefa;kune gasi remarara rine gasi rinokuvadza, zvinodikanwa kusarudza chinhu chesefa kana membrane zvinhu zvine adsorption uye kushandura mabasa.
Particulate mafirita akagadzirirwa kutora uye kubvisa zvimedu zvakasimba uye huruva kubva kumagasi.Coalescing mafirita zvinonyatso patsanura zvinosvibisa mvura zvakaita semvura nemadonhwe emafuta.Adsorbent mafirita anoshandisa activated kabhoni kana zvimwe adsorbent zvinhu kubvisa magasi, mhute uye hwema.Membrane mafirita anoshandisa akatetepa semipermeable membranes kuparadzanisa zvidimbu uye zvinosvibisa kubva kumagasi.
Kambani yedu inopa zvigadzirwa zvekusefa zvinosanganisira mafirita, Pleated Filter, Sintered Filter, sintered powder filter, air fluidized plates, waya mesh demisters, Wire Mesh Corrugated Packing, pack filter, etc. inoda kusarudzwa maererano nemamiriro akasiyana ekushanda uye zvinodiwa.Isu tinokwanisa kugadzirisa zvigadzirwa zveakasiyana maratidziro, saizi uye kunyatsosefa zvinoenderana nezvinodiwa nevatengi.
