Musi waChikunguru 3, 2022, kugadzirwa kwemakemikari eHaiyuan kwaive kwakajairwa, kunyanya kutarisisa basa rekuburitsa formaldehyde, kugadzirwa kwakajairika kwedoro repropargyl uye 1,4 butynediol yakapedzwa zvigadzirwa, uye kuongororwa kwewekishopu mukamuri repakati.
Chengetedza kushanda kwe formaldehyde mukati mezuva, uye kurudzira kuitwa kwekuchengetedza kwakakodzera nzvimbo dzinotsigira dzakadai sevashandisi 'kusabva, electrostatic grounding, sliding sleepers, emergency shut-off valve inspection, emergency emergency, nezvimwe.
Central control room Patrol: tarisa mukamuri yepakati yekudzora yenzvimbo dzakakura dzengozi senge propargyl doro, 1,4 butynediol tank purazi uye formaldehyde tank purazi kuona kuti zviratidzo zvese zvakajairika.
Kushanda kwemusangano wega wega:
Gasi rekupa musangano
1. Kumanikidzwa kwegasi regasi mumusangano wekugadzira gasi i3.69kpa, uye tembiricha yekushanda yemaseti maviri emajenareta A uye B i75-78 ℃.
2. Zvose zvakapwanyika calcium carbide particles inoshandiswa pakusanganiswa mumasikati ndeye 86.7kg, uye yakaongororwa calcium carbide powder i135kg.
3. Mvura inoiswa pachena pamudzi we weld crater wepombi yekubuda nayo yeNorth slurry pombi muplant yegasi (pakaitwa clip pekutanga), uye ramba uchigadzirisa kona kuti ugadzire clip.
Synthesis workshop
1. Iyo activation solution ye activation kettle A inoputirwa mugadziriro yegadziriro
2. Kushanda kwekugadzirisa mhinduro ye kettle B inopera pa20:50.
3. PH kukosha kwealkali yemvura mualkali Shongwe: 13.33
PH kukosha pamberi pealkali Shongwe: 6.36
PH kukosha kuseri kwealkali Shongwe: 7.51
PH kukosha kwekuchenesa: 12.52
4. Iyo acetylene inopa zvirimo mune synthesis workshop ndeye 90%, uye yekudzoka gasi yemukati i74%
Refining workshop
1. Zvinyorwa zvebutanediol zvakabviswa kubva diaphragm Tower: 65.7%, pH kukosha: 5.54, conductivity: 1237, tembiricha: 25 ℃.
2. Iyo methanol inogamuchira tembiricha yeshongwe yedealcoholization yakavharirwa pa73.5 ℃, uye zvirimo mupropargyl doro mumethanol kuyerwa i0.8
3. Ammonia mvura yakawedzerwa mu diaphragm tower mumasikati shift: 45L, kuvhura kweammonia dosing pump: 15%, frequency ye frequency converter: 100%, pH kukosha kwakayerwa nepH mita: 9.2
4. Kuvhurwa kwekudyisa kwe diaphragm tower mumusangano wekunatsa i100%, uye kuyerera i10.7m ³/h.Kuyerera kwakaderera, uye valve yepneumatic yemutsara mukuru inofanira kuparadzaniswa uye kuongororwa.Uye tanga iyo yekubatsira mutsara kugadzirisa kushanda.
5. Iko mafuta uye gasi yekuparadzanisa kapu yekuchengetedza yevhavha inodzvinyirira iri pasi peshongwe yekutanga mumusangano wekunatsa iri kuchembera uye kubuda.Inotsiviwa uye inoshandiswa.
6. Bvisa uye ongorora diaphragm tower feed flowmeter mumusangano wekunatsa, uye kumisa ammonia dosing metering pump,
Sewage treatment workshop
1. Tembiricha yemvura inotenderera: 31 ℃, vhura mafeni mana eshongwe inotonhorera
Teerera kune yakajairika kushanda kweDCS neAPC.
Haiyuan kemikari yagara yakasimba mukuchengetedza kugadzirwa kwekuchengetedza uye kuita basa rakasimba mukugadzira kuchengetedza.
