Nei mafirita emhepo anoshandiswa zvakanyanya?

Panguva iripo Mumakore achangopfuura, huwandu hwenhoroondo yemapapu hwave kumuka nekuda kwezvinhu zvakadai sekusvibiswa kwemhepo, nharaunda isingadzoreki, uye kusimuka kunoenderera mberi kwekuputa huwandu hwevanhu. Kushushikana kwevanhu uye kunetseka nezvengozi dzakavanzika dzinokonzerwa nekusvibiswa kwezvakatipoteredza kwakaita kuti uwedzere kuwedzera mukuziva kwakawanda kwekuziva nezvehuwandu hwese. Kutaura zvazviri, zvinoitika nguva zhinji zveHaze mumakore gumi apfuura zvakakonzerawo kukurumidza kukura kweiyo mhepo firita indasitiri mumakore mashoma apfuura. Nekuenderera mberi kwekuenderera mberi kwehunyanzvi hwekushanda kwemaindasitiri, kunyatsojeka uye hutsanana hweindasitiri kuri zvakare kugara tichivandudza. Naizvozvo, mafirita emhepo anowanzoshandiswa mukugadzirwa kwemaindasitiri. Isu tese tinoziva kuti kune yakakura yeguruva yakamiswa mumhepo, iyo isingakwanise kubatwa neziso rakashama. Naizvozvo, isu hatigone kubata maruva aya kuburikidza nenzira dzakajairika dzekuchenesa, asi mune dzakawanda nyaya, maruva aya anowanzove nemhedzisiro yekuvhiya kwavo. Semuenzaniso, kana guruva riri mumhepo rinowira pamusoro pekutenderera kwemushini, rinomhanyisa kupfeka kwezvinhu zvinotenderera, kuderedza chokwadi uye hupenyu hwemuchina. Guruva richipararira mumusangano rinogona kuderedza kuoneka, kubata chiono, kukanganisa mashandiro, uye kubereka kwehutapwa. Iko kushandiswa kwemhepo mafirita mukugadzirwa kwemaindasitiri kunogona kunatsa mweya uine guruva remahara uye uzvitumire mukati kuti uve nechokwadi chekuita mamuri dzakachena uye kuchena kwemhepo mumakamuri emhepo. Zvinowanzoshandiswa muindasitiri maindasitiri, pendi indasitiri, chikafu uye chinwiwa chinwiwa, bihopharmaceutical indasitiri, zvichingodaro.

Chinangwa chemhepo mafirita kuwana mhepo yakachena iyo inosangana nemitemo. Kazhinji, mafirita emhepo akagadzirirwa kubatwa uye adsorb guruva zvikamu zvehukuru hwakasiyana mumhepo, kuvandudza mhando yemhepo. Mafirita emakemikari haangatore chete adsorb guruva asi zvakare kunhuhwirira.
Mukuwedzera, nekuwedzera kwekuwedzera kwekudzivirirwa kwezvakatipoteredza pamabhizimisi, pane kunyanya zvinodiwa zvekusvibiswa kwemhepo. Kune iyo yekubvisa kunze kwemishini kubva kumafekitori, chinodiwa chakasimba chine chepfu. Dzimwe simbi dzinorema dzakadai saMercury, Arsenic, Chromium, Beryllium, etc. Zvakawanda zvine chepfu uye zvine simba kubvumirana. Panyaya yeMhepo Thupfu, United States neGermany yakapfuura nemutemo mutsva uye wakasimba. Mushure mekushandiswa kwemutemo mutsva wemutemo, muganho pane wekutakura mweya wakaderedzwa kubva kune yekutanga 20mg / m3 (standard) kusvika 010004mg / m3 (standard). Kuti uwane chinangwa ichi, mafekitori anoda mamwe mafirita epamberi kuti abvise submicron zvidimbu.
