I te Hūrae 3, 2022, he mahi noa te hanga matū Haiyuan, ko te nuinga o te tirotiro i te mahi tangohanga formaldehyde, te hanga noa o te waipiro propargyl me te 1,4 butynediol kua oti nga hua, me te tirotiro i te awheawhe i roto i te ruma whakahaere.
Tirotiro i te mahi formaldehyde i te awatea, me te tohe ki te whakatinana i nga waahi tautoko haumaru e tika ana penei i te kore e wehe atu nga kaiwhakahaere, te papa hiko, te moe reti, te tirotiro whana kati-atu, taputapu ohorere, aha atu.
Rūma whakahaere i te pokapū Tiaki: tirotirohia te rūma whakahaere i te pokapū o nga punaa morearea nui penei i te waipiro propargyl, 1,4 te paamu taika butynediol me te paamu taika formaldehyde kia pai ai nga tohu katoa.
Te whakahaere o ia awheawhe:
Awheawhe tuku hau
1. Ko te pehanga o te puna hau i roto i te awheawhe hanga hau he 3.69kpa, me te pāmahana whakahaere o nga huinga e rua o nga kaihanga A me B he 75-78 ℃.
2. Ko te tapeke o nga matūriki konupūmā carbide mongamonga e whakamahia ana mo te ranu i roto i te nekehanga ra ko te 86.7kg, me te paura konupūmā carbide kua whakamarohia he 135kg.
3. Ka puta te wai ki te putake o te rua o te paipa o te paipa putanga o te papu slurry Te Tai Tokerau i roto i te tipu hau (te waahi i mahia tuatahitia te topenga), me te whakatika tonu i te koki hei hanga i te topenga.
Awheawhe whakahiato
1. Ko te otinga whakakorikori o te kettle whakahohe A ka maminga ki roto i te huinga o te punaha
2. Ka mutu te whakahohenga o te otinga whakakorikori o te ketere whakakorikori B i te 20:50.
3. PH uara o te wai alkali i roto i te alkali Tower: 13.33
Uara PH i mua i te Tower alkali: 6.36
Uara PH i muri i te Pourewa alkali: 7.51
PH uara o te purepure: 12.52
4. Ko te ihirangi acetylene supply i roto i te awheawhe whakahiato he 90%, me te ihirangi hau hoki he 74%
Te awheawhe whakamahine
1. Ihirangi o te butanediol i tangohia mai i te diaphragm Tower: 65.7%, te uara pH: 5.54, te kawe: 1237, te pāmahana: 25 ℃.
2. Ko te methanol e whiwhi ana i te pāmahana o te pourewa whakangao ka piri ki te 73.5 ℃, ko te ihirangi o te waipiro propargyl i te methanol i whanganga he 0.8
3. Ko te wai haukini ka tapirihia ki roto i te pourewa diaphragm i te ra neke: 45L, te whakatuwheratanga o te papu haukini dosing: 15%, te auau o te huringa auau: 100%, te uara pH i whanganga e te mita pH: 9.2
4. Ko te whakatuwheratanga kai o te pourewa diaphragm i roto i te awheawhe whakamahine he 100%, a ko te rere he 10.7m ³/ h.He iti te rere o te rere, a ka wetewetehia, ka tirotirohia te valve pneumatic o te raina matua.A ka timata te mahi whakatikatika raina awhina.
5. Ko te kapu rokiroki whakawehenga hinu me te hau o te puera whakahaere pehanga kei raro o te pourewa tuatahi i roto i te awheawhe whakamahine kua koroheketia me te turuturu.Ka whakakapihia, ka whakamahia.
6. Wewetehia me te tirotiro i te ine rerenga whangai o te pourewa diaphragm i roto i te awheawhe para, ka mutu te papu inenga haukini,
Awheawhe maimoatanga parakaingaki
1. Te wera o te wai hurihanga: 31 ℃, whakatuwheratia e wha nga kaiwhaiwhai whakamatao
Kia tupato ki te mahi noa o te DCS me te APC.
Ko te matū Haiyuan i nga wa katoa he tino kaha ki te whakahaere i te whakaputanga haumaru me te mahi i te mahi totika ki te hanga haumaru.
