Imigaqo, iingenelo kunye nokungalunganga kwenkunkuma yegesi desulfurization kunye nenkqubo ye-denitrification

Ndiyakholelwa ukuba abahlobo abaninzi abacaci kakuhle malunga ne-desulfurization kunye nenkqubo ye-denitrification. Namhlanje, makhe ndazise umgaqo, iingenelo kunye nokungonakali kwenkunkuma yerhasi desulfurization kunye nenkqubo ye-denitrification?

Eyokuqala yitekhnoloji ye-desulfurization. Okwangoku, kukho intaphane yetekhnoloji ye-flue gas desulfurization. Ngokumalunga nokuba amanzi ongeziweyo kwinkqubo ye-desulfurization kunye nohlobo olomileyo nolumanzi lweemveliso ze-desulfurization, i-flue gas desulfurization inokwahlulwa ibe ngamacandelo amathathu: emanzi, eyomileyo kwaye eyomileyo. Itekhnoloji ye-Wet desulfurization ikhulile ngokwentelekiso, inokusebenza okuphezulu kunye nokusebenza okulula.

Emva koko kukho itekhnoloji ye-denitration. Ngokwendlela yokwenza initrogen oxides, amanyathelo obugcisa okunciphisa initrogen kunye nokukhutshwa kwezinto ezikhutshwayo anokwahlulwa abe ziindidi ezimbini:

Enye kukulawula ukusuka kumthombo. Lawula isizukulwana se-NOx ngexesha lokubala. Imilinganiselo yayo yobugcisa: ① isitshisi senitrogen esisezantsi; ② Ukutshiswa kwecandelo kwi-calciner kunye nombhobho ukulawula ubushushu bokutsha; ③ Guqula isikimu solungelelwaniso, wamkele imineralizer, kwaye unciphise iqondo lobushushu leclinker.

Omnye uvela ekupheleni. Amanyathelo obugcisa okulawula ukukhutshwa kwe-NOx kwigesi yombane ami ngolu hlobo lulandelayo: ① "istaged combustion+SNCR", eye yalingwa e-China; ② Ukuncitshiswa okukhethiweyo okungabonakaliyo (i-SNCR) iye yalingwa e-China; ③ Okwangoku, kukho imigca emithathu kuphela yovavanyo lokunciphisa okukhethiweyo kwe-catalytic (SCR) eYurophu; ③ Itekhnoloji ye-SNCR/SCR yokudibanisa i-denitration, itekhnoloji yesamente yasekhaya ayinamava ayimpumelelo; ④ Itekhnoloji ye-Biological denitration (phantsi kophuhliso).

Okwesibini kukusetyenziswa kwe-desulfurization kunye neteknoloji ye-denitration kumashishini ebhoyili. Itekhnoloji ye-desulfurization kunye ne-denitration yamashishini ebhoyila asebenzisa kakhulu amalahle okanye igesi njengendawo yokutshisa kubenzi bebhoyila abakhoyo basekhaya. Kwiibhoyili zamalahle, ukusetyenziswa kwasekhaya kwenkqubo evuthiweyo yi-FGD (usebenzisa i-absorbent okanye i-adsorbent ukususa i-sulfur dioxide kwi-flue gas) iteknoloji ye-desulfurization, kwaye i-denitration ilawulwa yi-SCR iteknoloji yokunciphisa i-catalytic ekhethiweyo.
