Ngomhla we-3 kaJulayi, i-2022, imveliso yeekhemikhali zaseHaiyuan yayiqhelekile, ingakumbi isongamela umsebenzi wokothula i-formaldehyde, imveliso eqhelekileyo ye-propargyl alcohol kunye ne-1,4 yeemveliso ezigqityiweyo ze-butynediol, kunye nokuhlolwa kwendawo yokusebenzela kwigumbi eliphakathi.
Ukongamela ukusebenza kwe-formaldehyde ngexesha lasemini, kwaye ukhuthaze ukuphunyezwa kwezixhobo ezixhasa ukhuseleko ezifanelekileyo ezifana nokungahambi kwabaqhubi, i-electrostatic grounding, i-sliding sleepers, ukuhlolwa kwe-valve yokuvala ngokukhawuleza, izixhobo eziphuthumayo, njl.
Igumbi lokulawula eliphakathi: ukugada igumbi lolawulo eliphakathi lemithombo yengozi enkulu efana ne-propargyl alcohol, i-1,4 yefama yetanki ye-butynediol kunye nefama yetanki ye-formaldehyde ukuqinisekisa ukuba zonke izikhombisi ziqhelekile.
Ukusebenza kweworkshop nganye:
Iworkshop yokubonelela ngegesi
1. Uxinzelelo lwe-gas reservoir kwi-workshop yokwenza igesi yi-3.69kpa, kunye nokushisa okusebenzayo kweeseti ezimbini zeejeneretha A kunye ne-B yi-75-78 ℃.
2. Isixa esipheleleyo se-calcium carbide particles esetyenzisiweyo ukuxuba kwi-shift yemini yi-86.7kg, kunye ne-calcium carbide powder efihliweyo yi-135kg.
3. Amanzi abonakaliswe kwingcambu ye-weld crater yombhobho wokuphuma wempompo yodaka oluseMantla kwiplanti yerhasi (apho ikliphu yayisenziwa kuqala), kwaye uqhubeke ulungelelanisa i-engile ukwenza ikliphu.
Iworkshop yokudibanisa
1. Isisombululo sokuvula seketile A sifakwe kwisethi yesistim
2. Ukusetyenziswa kwesisombululo sokuvula seketile B yokuvula iphele ngo-20:50.
3. Ixabiso le-PH ye-alkali yolwelo kwi-alkali Tower: 13.33
Ixabiso le-PH phambi kwe-alkali Tower: 6.36
Ixabiso le-PH emva kwe-alkali Tower: 7.51
PH ixabiso lokucoca: 12.52
4. Umxholo wokubonelela nge-acetylene kwi-workshop ye-synthesis yi-90%, kwaye i-content yegesi yokubuya yi-74%
Iworkshop yokucokisa
1. Umxholo we-butanediol okhutshwe kwi-diaphragm Tower: 65.7%, ixabiso le-pH: 5.54, i-conductivity: 1237, iqondo lokushisa: 25 ℃.
2. I-methanol efumana ubushushu be-dealcoholization tower ivalwe nge-73.5 ℃, kwaye umxholo we-propargyl alcohol kwi-methanol ulinganiswe ngu-0.8
3. Amanzi e-ammonia afakwe kwi-diaphragm tower kwi-shift yemini: 45L, ukuvulwa kwepompo yokudosa i-ammonia: i-15%, i-frequency converter frequency: 100%, ixabiso le-pH elilinganiswa ngemitha ye-pH: 9.2
4. Ukuvulwa kokutya kwi-diaphragm tower kwindawo yokusebenzela yokusulungekisa yi-100%, kwaye ukuhamba kwayo yi-10.7m ³/ h.Ukuhamba kuphantsi, kwaye i-valve ye-pneumatic yomgca oyintloko iya kuchithwa kwaye ihlolwe.Kwaye uqalise umsebenzi wokulungisa umgca oncedisayo.
5. Ikomityi yokugcina i-oyile kunye negesi yokwahlula i-valve yokulawula uxinzelelo emazantsi enqaba yokuqala kwindawo yokusebenzela yokusulungekisa iyaguga kwaye iyavuza.Iyatshintshwa kwaye isetyenziswe.
6. Qhoboza kwaye uhlole i-diaphragm tower feed flowmeter kwindawo yokusebenzela yokusulungekisa, kwaye uyeke impompo yokulinganisa idosi ye-ammonia,
Iworkshop yokucoca ugutyulo
1. Ubushushu bamanzi ajikelezayo: 31 ℃, vula iifeni zokupholisa ezine
Nika ingqalelo ekusebenzeni okuqhelekileyo kwe-DCS kunye ne-APC.
Ikhemikhali ye-Haiyuan ibisoloko ingqongqo kulawulo lwemveliso yokhuseleko kwaye yenza umsebenzi oqinileyo kwimveliso yokhuseleko.
