Ngomhla zi-3 kuJulayi, 2022, ukukhiqizwa kwamakhemikhali e-Haiyuan kwakujwayelekile, ikakhulukazi kuqondise umsebenzi wokuthulula i-formaldehyde, ukukhiqizwa okuvamile kotshwala be-propargyl kanye nemikhiqizo eqediwe engu-1,4 ye-butynediol, kanye nokuhlolwa kweshabhu ku-centralcontrolroom.
Ukwengamela ukusebenza kwe-formaldehyde phakathi nosuku, futhi unxuse ukuqaliswa kwezindawo ezisekela ukuphepha ezifanele njengokungasuki kwabaqhubi, ukumisa i-electrostatic, izindawo zokulala ezishelelayo, ukuhlolwa kwama-valve okuvaleka okuphuthumayo, okokusebenza kwezimo eziphuthumayo, njll.
Igumbi lokulawula eliphakathi Lokugada: gada igumbi lokulawula eliphakathi lemithombo eyingozi enkulu njenge-propargyl alcohol, 1,4 ipulazi lethangi le-butynediol kanye nepulazi lethangi le-formaldehyde ukuze uqinisekise ukuthi zonke izinkomba zijwayelekile.
Ukusebenza kweshabhu ngayinye:
Ishabhu yokuhlinzeka ngegesi
1. Ingcindezi yendawo yokugcina igesi endaweni yokusebenzela yokwenza igesi ingu-3.69kpa, futhi izinga lokushisa lokusebenza lamasethi amabili amajeneretha A no-B ngu-75-78 ℃.
2. Isamba esiphelele sezinhlayiya ze-calcium carbide ezichotshoziwe ezisetshenziselwa ukuxuba ngesikhathi sosuku ngu-86.7kg, kanti i-calcium carbide powder ehloliwe ingu-135kg.
3. Amanzi avezwa empandeni ye-weld crater yepayipi lokuphuma lephampu ye-slurry eNyakatho embonini yegesi (lapho isiqeshana senziwe khona ekuqaleni), futhi uqhubeke nokulungisa i-engeli ukuze wenze isiqeshana.
Synthesis workshop
1. Isixazululo sokwenza kusebenze iketela A lokuvula sifakwa kusethi yesistimu
2. Ukwenza kusebenze isixazululo sokuvula iketela B kuphela ngo-20:50.
3. Inani le-PH le-alkali ewuketshezi kumbhoshongo we-alkali: 13.33
Inani elingu-PH phambi kwe-alkali Tower: 6.36
Inani elingu-PH ngemuva kombhoshongo we-alkali: 7.51
PH inani lesihlanzi: 12.52
4. Okuqukethwe kokunikezwa kwe-acetylene ku-workshop yokuhlanganiswa ngu-90%, futhi okuqukethwe kwegesi ebuyayo kungu-74%
Ishabhu yokucwenga
1. Okuqukethwe kwe-butanediol ekhishwe ku-diaphragm Tower: 65.7%, inani le-pH: 5.54, conductivity: 1237, izinga lokushisa: 25 ℃.
2. Izinga lokushisa elithola i-methanol lombhoshongo we-dealcoholization lixhunywe ku-73.5 ℃, futhi okuqukethwe kotshwala be-propargyl ku-methanol kukalwa ngu-0.8
3. Amanzi e-ammonia engezwa embhoshongweni we-diaphragm ngesikhathi sokuhamba kwasemini: 45L, ukuvulwa kwephampu yokudosa i-ammonia: 15%, imvamisa yokuguqulela imvamisa: 100%, inani le-pH likalwa imitha ye-pH: 9.2
4. Ukuvulwa kokuphakelayo kombhoshongo we-diaphragm endaweni yokusebenzela yokucwenga kungu-100%, futhi ukugeleza kungu-10.7m ³/h.Ukugeleza kuphansi, futhi i-valve ye-pneumatic yomugqa oyinhloko izohlakazwa futhi ihlolwe.Bese uqala umsebenzi wokulungisa umugqa osizayo.
5. Inkomishi yokugcina okuhlukanisa uwoyela negesi yevalvu elawula ukucindezela phansi kombhoshongo wokuqala endaweni yokusebenzela yokucwenga iyaguga futhi iyavuza.Iyashintshwa futhi isetshenziswe.
6. Hlula futhi uhlole i-diaphragm tower feed flowmeter endaweni yokusebenzela yokucwenga, bese umisa iphampu yokulinganisa umthamo we-ammonia,
Indawo yokusebenzela yokuhlanza indle
1. Izinga lokushisa lamanzi ajikelezayo: 31 ℃, vula amafeni wombhoshongo wokupholisa amane
Naka ukusebenza okuvamile kwe-DCS ne-APC.
Ikhemikhali ye-Haiyuan ibilokhu iqinile ekulawuleni ukukhiqizwa kokuphepha futhi yenza umsebenzi oqinile ekukhiqizeni ukuphepha.
Isikhathi sokuthumela: Jul-29-2022
