Ka la 3 Phupu 2022, tlhahiso ea lik'hemik'hale ea Haiyuan e ne e tloaelehile, haholo-holo e okametse ts'ebetso ea ho theola formaldehyde, tlhahiso e tloaelehileng ea joala ea propargyl le lihlahisoa tse felileng tsa 1,4 butynediol, le tlhahlobo ea workshop e bohareng ba taolo.
Ela hloko ts'ebetso ea formaldehyde mots'ehare, 'me u khothaletse ho kengoa ts'ebetsong ha lits'ebeletso tse ts'ehetsang ts'ireletso tse joalo ka ho se tsamaee ha li-operator, electrostatic grounding, li-sliding sleepers, tlhahlobo ea li-valve tsa tšohanyetso, lisebelisoa tsa tšohanyetso, joalo-joalo.
Kamore e bohareng ea taolo ea Patrol: paterola phaposi ea taolo e bohareng ea mehloli e meholo ea kotsi joalo ka joala ba propargyl, polasi ea tanka ea 1,4 butynediol le polasi ea tanka ea formaldehyde ho netefatsa hore matšoao ohle a tloaelehile.
Ts'ebetso ea thupelo e 'ngoe le e 'ngoe:
Seboka sa phepelo ea khase
1. Khatello ea polokelo ea khase setsing sa ho etsa khase ke 3.69kpa, 'me mocheso o sebetsang oa lihlopha tse peli tsa lijenereithara A le B ke 75-78 ℃.
2. Kakaretso ea likaroloana tse silafetseng tsa calcium carbide tse sebelisetsoang ho tsoaka motšehare ke 86.7kg, 'me phofo ea calcium carbide e hloekisitsoeng ke 135kg.
3. Metsi a pepesehile motsong oa phula ea weld ea phaephe ea ho tsoa ea pompo ea slurry North setsing sa khase (moo sekotwana se neng se entsoe qalong), 'me u tsoele pele ho lokisa angle ho etsa sekotwana.
Synthesis workshop
1. Tharollo ea ts'ebetso ea ketlele ea activation A e pompeloa ka har'a sete ea sistimi
2. Ts'ebetso ea tharollo ea ts'ebetso ea kettle ea activation B e qetella ka 20:50.
3. PH boleng ba alkali ea metsi ka alkali Tower: 13.33
PH boleng ka pel'a alkali Tower: 6.36
PH boleng ka morao ho alkali Tower: 7.51
PH boleng ba ho hloekisa: 12.52
4. Likahare tsa phepelo ea acetylene kopanong ea synthesis ke 90%, 'me khase e khutlang ke 74%
Mosebetsi oa ho hloekisa
1. Likahare tsa butanediol tse ntšitsoeng ho diaphragm Tower: 65.7%, pH bohlokoa: 5.54, conductivity: 1237, mocheso: 25 ℃.
2. Mocheso o amohelang methanol oa tora ea dealcoholization o hokahane ho 73.5 ℃, 'me litaba tsa joala ba propargyl ka methanol ke 0.8
3. Metsi a ammonia a kentsoeng tora ea diaphragm nakong ea ts'ebetso ea letsatsi: 45L, ho buloa ha pompo ea dosing ea ammonia: 15%, frequency converter frequency: 100%, pH boleng bo lekantsoeng ka pH meter: 9.2
4. Pulo ea phepelo ea tora ea diaphragm ka har'a workshop ea tlhoekiso ke 100%, 'me phallo ke 10.7m ³/h.Phallo e tlase, 'me valve ea pneumatic ea mohala o ka sehloohong e tla aroloa ebe e hlahlojoa.Ebe u qala ts'ebetso ea ho lokisa mela e thusang.
5. Senoelo sa polokelo ea karohano ea oli le khase ea valve e laolang khatello e ka tlaase ho tora ea pele ea workshop ea ho hloekisa e tsofala ebile ea lutla.E nkeloa sebaka ebe e sebelisoa.
6. Hlōla le ho hlahloba phallo ea phepelo ea tora ea diaphragm sebakeng sa ho hloekisoa, 'me u emise pompo ea metering ea ammonia,
Thupelo ea ho hloekisa likhoerekhoere
1. Mocheso oa metsi a potolohang: 31 ℃, bula li-fan tse 'ne tsa tora ea ho pholisa
Ela hloko ts'ebetso e tloaelehileng ea DCS le APC.
K'hemik'hale ea Haiyuan esale e le thata taolong ea tlhahiso ea polokeho mme e etsa mosebetsi o tiileng tlhahisong ea polokeho.
