Nkhani yachiwiri ya dongosolo loperekera gasi

Single station system - Muzinthu zina, gasi amagwiritsidwa ntchito kuwongolera chidacho.Mwachitsanzo, continuous emission monitoring system (CEMS) imangofunika kuyesa mpweya kwa mphindi zingapo patsiku.Izi sizikutanthauza kuti kutembenuka kwakukulu kodziwikiratu.Komabe, mapangidwe a njira yobweretsera sayenera kulepheretsa gasi wowongolera kuti asaipitsidwe ndikuchepetsa mtengo wokhudzana ndi kusintha kwa silinda.

Njira imodzi yokhala ndi mabulaketi ndi yankho labwino pamapulogalamu otere.Amapereka kulumikizana kotetezeka komanso kothandiza komanso kusinthidwa kwa masilindala, popanda kulimbana ndi wowongolera.Pamene mpweya uli ndi chigawo chowononga monga HCl kapena NO, gulu la purge liyenera kuikidwa muzowonjezereka kuti lichotsere chowongolera ndi mpweya wa inert (kawirikawiri nayitrogeni) kuteteza dzimbiri.Single / station zochulukitsa zithanso kukhala ndi mchira wachiwiri.Dongosololi limalola mwayi wopeza masilindala owonjezera ndikuyimirira.Kusintha kumachitika pamanja pogwiritsa ntchito silinda cutoff valve.Kusintha kumeneku nthawi zambiri kumakhala koyenera kuwongolera mpweya chifukwa kusakanikirana koyenera kwa zosakaniza nthawi zambiri kumasiyana ndi masilinda.

Semi-automatic switching system - Ntchito zambiri ziyenera kugwiritsidwa ntchito mosalekeza komanso / kapena zokulirapo kuposa kuchuluka kwamafuta omwe amagwiritsidwa ntchito ndi malo amodzi.Kuyimitsidwa kulikonse kwa gasi kungayambitse kulephera kwa kuyesa kapena kuwononga, kutayika kwa zokolola kapena kutha kwa malo onse.The semi-automatic switching system imatha kusintha kuchokera ku botolo lalikulu la gasi kapena silinda yamafuta osungira popanda kusokoneza, kuchepetsa mtengo wanthawi yayitali.Botolo la gasi kapena gulu la silinda likawotcha utsi, makinawo amangosintha kupita ku silinda yamagetsi yopumira kapena gulu la silinda kuti apeze kutuluka kosalekeza kwa gasi.Wogwiritsa ntchito amalowetsa botolo la gasi ngati silinda yatsopano, pomwe mpweya umayendabe kuchokera kumbali yosungira.Valavu yanjira ziwiri imagwiritsidwa ntchito kuwonetsa mbali yayikulu kapena mbali yopuma posintha silinda.
