Ukoresheje urugero rw'amashanyarazi akomoka ku makara ya sisitemu yo gukwirakwiza gaz (FGD) nk'urugero, iri sesengura risuzuma ibibazo biri muri sisitemu y’amazi gakondo ya FGD, nk'ibishushanyo mbonera ndetse n'ibiciro byo kunanirwa ibikoresho. Binyuze muburyo bwiza bwo guhindura no guhindura tekinike, ibintu bikomeye mumazi yanduye byagabanutse, bituma imikorere ya sisitemu isanzwe no kugabanya amafaranga yo gukora no kuyitaho. Hatanzwe ibisubizo bifatika hamwe nibyifuzo, bitanga umusingi uhamye wo kugera kumazi ya zeru mugihe kizaza.
1. Incamake ya sisitemu
Amashanyarazi akoreshwa namakara asanzwe akoresha inzira ya hekeste-gypsumu itose ya FGD, ikoresha hekeste (CaCO₃) nkuwinjiza. Iyi nzira byanze bikunze itanga amazi mabi ya FGD. Muri iki kibazo, sisitemu ebyiri zitose za FGD zisangiye igice kimwe cyo gutunganya amazi mabi. Inkomoko y’amazi ni gypsum cyclone yuzuye, itunganywa hakoreshejwe uburyo gakondo (sisitemu ya tank-tank) ifite ubushobozi bwa 22.8 t / h. Amazi mabi yatunganijwe avomerwa km 6 kugirango ajugunywe umukungugu.
2. Ibibazo byingenzi muri sisitemu yumwimerere
Diaphragm yo gukuramo pompe akenshi yamenetse cyangwa ikananirwa, bikarinda imiti ikomeza. Igipimo kinini cyo kunanirwa muri plaque-na-frame ya filteri ya pompe na pompe yamashanyarazi byongereye akazi kubakozi kandi bikabuza kuvanaho imyanda, gutinda kwimuka mubisobanuro.
Amazi mabi, akomoka kuri gypsum cyclone yuzuye, yari afite ubucucike bwa kg 1040 / m³ hamwe na 3.7%. Ibi byangije ubushobozi bwa sisitemu yo gukomeza gusohora amazi yatunganijwe no kugenzura ibyangiza ion byangiza.
3. Guhindura Ibanze
Kunoza imiti ikoreshwa:
Ibindi bikoresho bya shimi byashyizwe hejuru ya sisitemu ya tank-tank kugirango harebwe ibipimo bihoraho binyuze mu rukuruzi, bigenzurwa na anmetero yibanze kumurongo.
Igisubizo: Kunoza ubwiza bwamazi, nubwo ubutayu bwari bukenewe. Gusohora buri munsi byagabanutse kugera kuri 200 m³, ntibyari bihagije kugirango imikorere ihamye ya sisitemu ebyiri za FGD. Ibiciro byo kunywa byari byinshi, ugereranije 12 CNY / toni.
Gukoresha Amazi Yanduye Kurwanya Umukungugu:
Amapompe yashizwe kumurongo usobanutse kugirango yereke igice cyamazi yanduye kuri silo yivu yo kuvanga no guhumeka.
Igisubizo: Kugabanya umuvuduko kurubuga rwajugunywe ariko bikomeza kuvamo umuvuduko mwinshi no kutubahiriza ibipimo bisohoka.
4. Ingamba zo Gukwirakwiza Muri iki gihe
Hamwe n’amabwiriza akomeye y’ibidukikije, kongera sisitemu byari ngombwa.
4.1 Guhindura imiti no gukomeza gukora
Yagumanye pH hagati ya 9-10 binyuze mu kongera imiti:
Imikoreshereze ya buri munsi: lime (45 kg), coagulants (75 kg), na flocculants.
Yiyemeje gusohora 240 m³ / kumunsi wamazi meza nyuma yimikorere ya sisitemu rimwe na rimwe.
4.2 Gusubiramo ibyihutirwa byihutirwa
Gukoresha inshuro ebyiri ikigega cyihutirwa:
Mugihe cyo kumanura: Kubika buhoro.
Mugihe cyo gukora: Ubutaka busanzwe bwo kuvoma amazi meza.
Gukwirakwiza:
Wongeyeho valve no kuvoma kurwego rutandukanye kugirango bishoboke gukora byoroshye.
Gypsum yashizwemo yasubijwe muri sisitemu yo kuvoma cyangwa kongera gukoresha.
4.3 Guhindura sisitemu
Kugabanya ubukana bwamazi mumazi yinjira muguhindura filtrate muri sisitemu yo kuvoma umukandara wa vacuum mukigega cyamazi yanduye.
Kongera imbaraga zo gutembera mukugabanya ibihe byo gutura hakoreshejwe imiti ikoreshwa mubigega byihutirwa.
5. Inyungu zo Gukwirakwiza
Kongera ubushobozi:
Gukomeza gukora hamwe no gusohora buri munsi m 400 zirenga zamazi yanduye.
Igenzura ryingirakamaro rya ion mugukoresha.
Ibikorwa byoroshe:
Yakuyeho gukenera isahani-na-ikadiri ya filteri.
Kugabanya imirimo yo gutunganya imyanda.
Sisitemu Yizewe Yizewe:
Ihinduka ryinshi muri gahunda yo gutunganya amazi mabi.
Ibikoresho byo hejuru byizewe.
Kuzigama:
Imikoreshereze yimiti yagabanutse kugeza kuri lime (1,4 kg / t), coagulants (0.1 kg / t), na flocculants (0.23 kg / t).
Igiciro cyo kuvura cyamanutse kugera kuri 5.4 CNY / toni.
Kuzigama buri mwaka hafi 948.000 CNY mugiciro cyimiti.
Umwanzuro
Gutezimbere kwa sisitemu y’amazi ya FGD byatumye habaho kunoza imikorere, kugabanya ibiciro, no kubahiriza amahame akomeye y’ibidukikije. Izi ngamba zikora nka sisitemu isa nugushaka kugera kumazi ya zeru no kuramba kuramba.
