Kapangidwe ndi mfundo ntchito desulfurization nsanja

Pakali pano, mavuto a chilengedwe akuchulukirachulukira.Desulfurization zipangizo ndi waukulu njira kulamulira sulfure dioxide.Lero, tiyeni tikambirane za kapangidwe ndi mfundo ntchito ya desulfurization nsanja ya zipangizo desulfurization.

Chifukwa cha opanga osiyanasiyana, mawonekedwe amkati a nsanja ya desulfurization ndi yosiyana.Nthawi zambiri, nsanja ya desulfurization imagawika m'magawo atatu akuluakulu opopera, zigawo za whitening ndi demisting layers.

1. Utsi wosanjikiza

Utsi wosanjikiza umapangidwa ndi mapaipi opopera komanso mitu yopopera.The desulfurization madzi munali LH fumbi kuchotsa chothandizira mu zozungulira thanki amalowa kutsitsi wosanjikiza pansi zochita za slurry mpope.Mutu wa kutsitsi umapopera sodium hydroxide mu madzi a desulfurization omwe amalumikizana ndi mpweya wa flue countercurrent ndipo amachitira ndi sulfure dioxide mu mpweya wa flue kupanga sodium sulfite.

2. De whitening wosanjikiza

Bleaching wosanjikiza wapangidwa ndi yozizira nsanja ndi kuzirala chitoliro.The flue mpweya amalowa de whitening wosanjikiza, ndi kuzirala chipangizo de whitening wosanjikiza amachepetsa kutentha kwa chitoliro mpweya, kuti nthunzi madzi mu mpweya flue ndi liquefied pasadakhale ndipo umayenda pansi khoma lamkati la nsanja desulfurization mu desulfurization kuzungulira dongosolo, kuti akwaniritse cholinga cha desulfurization.

3. Demist wosanjikiza

The mpweya mpweya amalowa demister wa gawo lomaliza la nsanja desulfurization kuchokera pansi mpaka pamwamba, ndi demister amachotsa chifunga mu mpweya flue.Mpweya woyeretsedwa umatulutsidwa mu chimney.
