Pa Julayi 3, 2022, kupanga mankhwala a Haiyuan kunali kwabwinobwino, makamaka kuyang'anira ntchito yotsitsa formaldehyde, kupanga mwachizolowezi cha mowa wa propargyl ndi zinthu 1,4 za butynediol zomalizidwa, komanso kuyendera malo ochitira msonkhano m'chipinda chapakati.
Yang'anirani ntchito ya formaldehyde masana, ndikulimbikitsa kukhazikitsidwa kwa zida zothandizira chitetezo monga osachoka, ma electrostatic grounding, sliding sleepers, kuyang'anira ma valve otseka mwadzidzidzi, zida zadzidzidzi, ndi zina zambiri.
Chipinda chapakati choyang'anira Patrol: kuyang'anira chipinda chapakati choyang'anira malo omwe ali pachiwopsezo chachikulu monga mowa wa propargyl, famu ya thanki ya butynediol 1,4 ndi famu ya thanki ya formaldehyde kuti muwonetsetse kuti zisonyezo zonse ndizabwinobwino.
Ntchito ya msonkhano uliwonse:
Ntchito yopangira gasi
1. Kuthamanga kwa malo osungiramo gasi mu msonkhano wopangira mpweya ndi 3.69kpa, ndipo kutentha kwa ma seti awiri a jenereta A ndi B ndi 75-78 ℃.
2. Kuchuluka kwa tinthu tating'ono ta calcium carbide timene timagwiritsa ntchito kusakaniza masana ndi 86.7kg, ndipo ufa woyesedwa wa calcium carbide ndi 135kg.
3. Madzi poyera pa muzu wa kuwotcherera crater wa kubwereketsa payipi wa North slurry mpope mu mpweya zomera (kumene kopanira poyamba), ndi kupitiriza kusintha ngodya kuti kopanira.
Synthesis workshop
1. The activation solution ya activation ketulo A imaponyedwa mu dongosolo
2. Kutsegula kwa njira yothetsera ketulo B kumatha pa 20:50.
3. PH mtengo wa alkali wamadzimadzi mu alkali Tower: 13.33
Mtengo wa PH kutsogolo kwa alkali Tower: 6.36
Mtengo wa PH kumbuyo kwa alkali Tower: 7.51
PH mtengo woyeretsa: 12.52
4. Zomwe zili mu acetylene mu msonkhano wa kaphatikizidwe ndi 90%, ndipo mpweya wobwerera ndi 74%
Kuyeretsa workshop
1. Zomwe zili mu butanediol yotengedwa ku diaphragm Tower: 65.7%, pH mtengo: 5.54, conductivity: 1237, kutentha: 25 ℃.
2. The methanol kulandira kutentha kwa dealcoholization nsanja ndi zopiringizika pa 73.5 ℃, ndipo zili propargyl mowa mu methanol kuyeza ndi 0,8
3. Madzi a ammonia amawonjezeredwa munsanja ya diaphragm masana: 45L, kutsegula kwa mpope wa ammonia: 15%, ma frequency converter: 100%, pH mtengo woyezedwa ndi pH mita: 9.2
4. Kutsegulira kodyetsa kwa diaphragm tower mu msonkhano woyenga ndi 100%, ndipo kutuluka kwake ndi 10.7m ³/h.Kuthamanga kumakhala kochepa, ndipo valve ya pneumatic ya mzere waukulu idzaphwanyidwa ndikuwunikiridwa.Ndipo yambani ntchito yosinthira mzere wothandizira.
5. Kapu yosungiramo mafuta ndi gasi yolekanitsa valavu yoyendetsera pansi pa nsanja yoyamba mu msonkhano woyenga ndikukalamba komanso kutayikira.Amasinthidwa ndikugwiritsidwa ntchito.
6. Masulani ndi kuyang'ana cholumikizira cha diaphragm tower feed flowmeter mumsonkhano woyenga, ndikuyimitsa pampu yoyezera ammonia,
Ntchito yochizira zimbudzi
1. Kutentha kwamadzi ozungulira: 31 ℃, tsegulani mafani anayi a nsanja yozizirira
Samalani ndi magwiridwe antchito a DCS ndi APC.
Mankhwala a Haiyuan nthawi zonse amakhala okhwima pakuwongolera chitetezo ndipo amagwira ntchito yolimba pakupanga chitetezo.
