Te rere o te tukanga omira roera poutū whakakorenga whanarikiHe maeneene te pūnaha, he penapena te haumitanga, ā, he māmā te whakahaere whakaputa. I te wā e whiriwhiri ana i te mahere tukanga whakaputa me te whiriwhiri taputapu mō te paura kōhatu whakawātea, me whakamahi ngā tukanga me ngā hangarau hou kua pakari, pono hoki, he ōhanga, he whaitake, he whai hua, he pono hoki. Ko HCMilling (Guilin Hongcheng), hei hoahoa kaupapa me te kaihanga o te pūnaha mira roera poutū whakawātea, ka whakauru i te pānga whakawātea o te mira roera poutū.

HLMmira roera poutū whakakorenga whanariki

He maha ngā āhuatanga matua e pā ana ki te whai huatanga o te desulfurization:

1. Te taumata kōhatu

Ka whakatauhia te taumata o te kōhatu kōhatu mā te ihirangi CaO. Ko te ihirangi CaO teitei rawa o te kōhatu kōhatu parakore he 56%. Ko te teitei ake o te parakore o te kōhatu kōhatu, ko te pai ake o te whai huatanga o te tango whanariki. Hei kaihoahoa tukanga, i te wā e hoahoa ana i ngā kai, kaua e tatau noa i tōna hanganga matū, engari me mārama hoki ki ōna āhuatanga ā-tinana. Ko te ihirangi konupūmā waikura o te kōhatu kōhatu tuatahi he 48% – 54%; Kāore e hiahiatia he ihirangi CaO teitei ake mō te kōhatu kōhatu. He teitei te parakore o te kōhatu kōhatu CaO>54%, ā, kua whakamārōhia. Kāore e ngāwari ki te huri, ā, he kaha te pumau o te matū, nō reira kāore e pai mō te whakamahi hei tango whanariki.

2. Te pai o te paura kōhatu

Ko te iti o te rahi o te matūriki o te paura kōhatu, ko te nui ake o te horahanga mata motuhake. I te mea he tauhohenga rua-wāhanga te tauhohenga whakarewa o te kōhatu, ā, he rite tonu tōna tere tauhohenga ki te horahanga mata motuhake o ngā matūriki kōhatu, he pai te mahi whakarewa o ngā matūriki kōhatu pai ake, he nui ake ngā tere tauhohenga e pā ana, he nui ake te pai o te tango whanariki me te whakamahinga o te kōhatu, engari ko te iti o te rahi o te matūriki kōhatu, ko te nui ake o te whakapaunga pūngao kuru. I te nuinga o te wā, ko te tere paahitanga o te paura kōhatu paahitanga i te tatari 325 mata (44 microns) he 95%.

I taua wā anō, e pā ana te rahi o te matūriki o te paura kōhatu ki te kounga o te kōhatu. Hei whakarite kia eke te pai o te tango whanariki me te tere whakamahinga o te kōhatu ki tētahi taumata, ina nui te ihirangi poke i roto i te kōhatu, me huri te kōhatu kia angiangi ake.

Te hangarau whakarite paura kōhatu mā te whakamahi i mira roera poutū whakakorenga whanarikipūnaha:

Mō te tukanga FGD e whakamahi ana i te paura kōhatu hei tango whanariki, me uru te paura kōhatu ki te tauhohenga wai totoka e rua-wāhanga, ā, he pai te tere tauhohenga ki te horahanga mata motuhake o ngā matūriki kōhatu. Ko te iti o te rahi o te matūriki o ngā matūriki paura kōhatu, ko te nui ake o te horahanga mata motuhake mā te taumaha. He pai te wairewa o ngā matūriki kōhatu, ā, he teitei ngā tere tauhohenga e pā ana. Heoi, ko te iti o te rahi o te matūriki o te kōhatu, ko te teitei ake o te whakapaunga pūngao o te kuru. I te nuinga o te wā, ko te tere paahitanga o te paura kōhatu e paahi ana i te tatari 325 mata (44 microns) he 95%. I taua wā anō, ko te rahi o te matūriki o te paura kōhatu e pā ana ki te kounga o te kōhatu. Hei whakarite kia eke te pai o te tango whanariki me te tere whakamahi kōhatu ki tētahi taumata, ina teitei te ihirangi poke i roto i te kōhatu, me kuru pai ake te kōhatu. Ka whakamahia te hangarau mira ngongo tuku iho hei whakarite i te paura kōhatu, he nui te whakapaunga pūngao, he iti te putanga, he uaua te rere o te tukanga, ā, he uaua ki te whakahaere i te pai me te whakarōpūtanga matūriki. I te whanaketanga o te hangarau huri, ka whakamahia te hangarau huri mira roera poutū. Nā te kaupapa huri paparanga rauemi, he iti te whakapaunga pūngao (20-30% te iti iho i te whakapaunga hiko o te mira ngongo), he pumau te hanganga matū o te hua, he ōrite te whakarōpūtanga matūriki, ā, he māmā te rere o te tukanga.

Ko te kōhatu e tomo ana ki te wheketere ka tukuna ki roto i te hopper mā te taraka, mā te forklift rānei, ā, ka kuruhia te kōhatu i te wā kotahi. Ka tukuna ngā poraka kōhatu ki te kuru mā te pereti whāngai. Ko te rahi o te matūriki whāngai ka whakahaeretia i te 400-500mm, ā, ko te rahi o te matūriki tuku ka whakahaeretia i te 15mm pea. Ka tukuna te kōhatu kuru ki roto i te silo kōhatu mā te taputapu kawe, ā, ka whakauruhia te tihi silo ki te kohikohi puehu kotahi hei tango puehu. Ka inehia te kōhatu kuru ka whakaemihia e te pauna whitiki whakahaere tere i raro o te silo, kātahi ka whāngaihia ki roto i te mira roera poutū e te kawe whitiki hei huri. Ko te hua kua oti ko te paura kōhatu he 250 mata te matotoru. I muri i te hurihanga ka haria te paura kōhatu ki te whare putunga hua kua oti hei penapena. Ko te tihi o te whare putunga he kohikohi puehu kotahi hei tango puehu. Ka tukuna ngā hua kua oti ki te taraka tāke nui hei tuku mā te mīhini nui i raro o te whare putunga.

Te pānga o te whakakorenga whanariki omira roera poutū:

Te tukanga huri oHLMmira roera poutū E whakamahi ana i te mātāpono huri paparanga rauemi, me te pēhanga huri ka taea te whakarite, te haruru iti, te iti o te whakapaunga pūngao, te iti o te kakahu, te kaha urutau ki ngā rauemi, te rere o te tukanga me te pai o te pūnaha. Ka whakahaerehia te pūnaha katoa i raro i te pēhanga kino me te iti o te parahanga puehu. Ko te tukanga huri o te mira roera poutū he rite te whakarōpūtanga o te witi, he pai te whakarite o te hua (ka taea e te pai o te hua te eke ki te 600 mata, neke atu rānei), ā, ka taea te ine me te whakatika tere i te pai o te hua.
