Matakan Tsari

Mahimman matakan tsari na wannan hanyar desulphurisation rigar sune:

• Absorbent shiri da dosing
• Cire SOx (HCl, HF)
• Dewatering da kwandishan na samfur

A cikin wannan hanyar, ana iya amfani da farar ƙasa (CaCO3) ko quicklime (CaO) azaman abin sha. Zaɓin ƙari wanda za'a iya ƙara bushewa ko azaman slurry ana yin shi bisa ƙayyadaddun ƙayyadaddun ƙayyadaddun iyaka na aikin. Don cire sulfur oxides (SOx) da sauran abubuwan acidic (HCl, HF), ana kawo iskar gas ɗin cikin hulɗa mai ƙarfi tare da slurry mai ɗauke da ƙari a cikin yankin sha. Ta wannan hanyar, ana samar da mafi girman wuri mai yuwuwa don canja wurin taro. A cikin yankin sha, SO2 daga iskar hayaki yana amsawa tare da abin sha don samar da calcium sulphite (CaSO3).

Ana tattara slurry na farar ƙasa mai ɗauke da alli sulfite a cikin abin sha. Ana ci gaba da ƙara dutsen farar ƙasa da ake amfani da shi don tsaftace iskar hayaƙi a cikin ma'auni don tabbatar da cewa ƙarfin tsaftacewa na abin sha ya kasance akai-akai. Sa'an nan kuma a sake juye slurry zuwa yankin sha.

Ta hanyar hura iska a cikin sump na absorber, gypsum yana samuwa daga calcium sulphite kuma an cire shi daga tsarin a matsayin wani ɓangare na slurry. Dangane da buƙatun ingancin samfurin ƙarshe, ana yin ƙarin magani don samar da gypsum mai kasuwa.

Injiniyan Shuka

A cikin rigar bututun iskar gas, buɗaɗɗen masu ɗaukar hasumiya na feshi sun yi galaba waɗanda aka raba su zuwa manyan yankuna biyu. Waɗannan su ne yankin sha da aka fallasa ga iskar hayaƙin hayaƙi da kuma abin sha, wanda slurry na farar ƙasa ke makale da tattarawa. Don hana adibas a cikin sump na abin sha, ana dakatar da slurry ta hanyoyin hadawa.

Shirye-shiryen nozzles a cikin hasumiya mai feshi yana da mahimmancin mahimmanci don kawar da ingancin abin sha. Saboda haka inganta kwarara yana da matukar mahimmanci. A cikin kawar da hazo, ɗigon da aka ɗauka daga yankin sha da iskar gas ɗin hayaƙi ana mayar da su cikin tsari. A wurin magudanar ruwa, iskar gas mai tsafta ya cika kuma ana iya cire shi kai tsaye ta hasumiya mai sanyaya ko jika. Optionally ana iya dumama iskar gas mai tsafta kuma a tura shi zuwa busasshen tari.

slurry da aka cire daga sump absorber yana jurewa na farko ta hanyar hydrocyclones. Gabaɗaya wannan slurry da aka riga aka tattara ana ƙara deɓar ruwa ta hanyar tacewa. Ruwan, wanda aka samo daga wannan tsari, ana iya mayar da shi da yawa zuwa abin sha. Ana cire ƙaramin sashi a cikin tsarin jigilar jini a cikin nau'in ruwan sharar gida.

Rushewar iskar gas a cikin masana'antun masana'antu, masana'antar wutar lantarki ko tsire-tsire masu ƙona sharar gida ya dogara da nozzles waɗanda ke ba da garantin aiki daidai na dogon lokaci kuma suna jure yanayin muhalli mai tsananin muni. Tare da tsarin sa na bututun ƙarfe, Lechler yana ba da ƙwararru da hanyoyin da suka dace da aikace-aikacen don masu goge-goge ko masu feshi da sauran matakai a cikin lalata iskar gas (FGD).
