Thaum Lub Xya Hli 3, 2022, Haiyuan tshuaj lom neeg ntau lawm yog qhov qub, feem ntau yog saib xyuas cov haujlwm formaldehyde unloading, ib txwm tsim cov cawv propargyl thiab 1,4 butynediol cov khoom tiav, thiab kev tshuaj xyuas ntawm lub rooj cob qhia hauv nruab nrab.
Saib xyuas kev ua haujlwm formaldehyde thaum nruab hnub, thiab hais kom ua raws li cov kev pabcuam kev nyab xeeb xws li cov neeg ua haujlwm tsis tawm mus, electrostatic grounding, sliding sleepers, thaum muaj xwm ceev kaw-off valve tshuaj xyuas, khoom siv thaum muaj xwm ceev, thiab lwm yam.
Chav tswj hwm hauv nruab nrab Patrol: saib xyuas lub hauv paus tswj chav ntawm cov chaw muaj kev phom sij loj xws li cawv propargyl, 1,4 butynediol tank ua liaj ua teb thiab formaldehyde tank ua liaj ua teb kom ntseeg tau tias txhua qhov ntsuas tau zoo.
Kev ua haujlwm ntawm txhua qhov kev cob qhia:
Gas muab kev cob qhia
1. Lub siab ntawm cov roj reservoir nyob rau hauv lub rhiav ua roj yog 3.69kpa, thiab kev khiav hauj lwm kub ntawm ob pawg ntawm generators A thiab B yog 75-78 ℃.
2. Tag nrho cov khoom ntawm crushed calcium carbide hais siv rau kev sib xyaw ua haujlwm hauv nruab hnub yog 86.7kg, thiab cov tshuaj ntsuam xyuas calcium carbide hmoov yog 135kg.
3. Cov dej raug nthuav tawm ntawm cov hauv paus hniav ntawm lub qhov hluav taws xob qhov hluav taws xob ntawm lub qhov hluav taws xob ntawm North slurry twj tso kua mis nyob rau hauv cov roj cog (qhov twg cov clip yog Ameslikas tsim), thiab txuas ntxiv kho lub kaum sab xis los ua cov clip.
Synthesis Rhiav
1. Cov kev daws teeb meem ntawm activation kettle A yog pumped rau hauv cov txheej txheem
2. Kev ua kom muaj zog ntawm kev ua kom muaj zog ntawm kev ua kom lub hwj chim B xaus ntawm 20:50.
3. PH tus nqi ntawm cov kua alkali hauv alkali ntauwd: 13.33
PH tus nqi pem hauv ntej ntawm alkali ntauwd: 6.36
PH tus nqi tom qab alkali Ntauwd: 7.51
PH tus nqi ntawm purifier: 12.52
4. Cov ntsiab lus ntawm acetylene muab cov ntsiab lus nyob rau hauv lub synthesis Rhiav yog 90%, thiab cov ntsiab lus roj rov qab yog 74%.
Refining Rhiav
1. Cov ntsiab lus ntawm butanediol rho tawm los ntawm diaphragm Ntauwd: 65.7%, pH tus nqi: 5.54, conductivity: 1237, kub: 25 ℃.
2. Lub methanol tau txais qhov kub thiab txias ntawm lub dealcoholization ntauwd yog interlocked ntawm 73.5 ℃, thiab cov ntsiab lus ntawm propargyl cawv hauv methanol ntsuas yog 0.8
3. Ammonia dej ntxiv rau hauv diaphragm ntauwd nyob rau hauv lub hnub hloov: 45L, qhib ammonia dosing twj tso kua mis: 15%, zaus converter zaus: 100%, pH tus nqi ntsuas pH meter: 9.2
4. Kev pub mis qhib ntawm diaphragm ntauwd hauv refining rhiav yog 100%, thiab qhov ntws yog 10.7m ³ / h.Cov dej ntws tsawg, thiab pneumatic valve ntawm txoj kab tseem ceeb yuav tsum tau muab tshem tawm thiab tshuaj xyuas.Thiab pib qhov kev pabcuam kev hloov kho txoj haujlwm.
5. Cov roj thiab cov roj sib cais cia lub khob ntawm lub siab tswj lub valve nyob rau hauv qab ntawm thawj pej thuam nyob rau hauv lub refining rhiav yog aging thiab to.Nws yog hloov thiab muab tso rau hauv kev siv.
6. Tshem tawm thiab tshuaj xyuas lub diaphragm ntauwd pub flowmeter nyob rau hauv lub rhiav refining, thiab nres lub ammonia dosing metering twj tso kua mis,
Kev kho dej phwj tuaj
1. Circulating dej kub: 31 ℃, qhib plaub lub kiv cua txias ntauwd
Ua tib zoo saib xyuas kev ua haujlwm ntawm DCS thiab APC.
Haiyuan tshuaj ib txwm nruj me ntsis hauv kev tswj hwm kev nyab xeeb thiab ua haujlwm ruaj ntseg hauv kev tsim khoom.
