Muindasitiri yesimbi, mapaipi esimbi chinhu chakakosha chakakosha uye anoshandiswa zvakanyanya mukuvaka, michina, indasitiri yemakemikari, uye mamwe minda. Iyo yesimbi pombi alkali yekuwacha maitiro, sechinhu chakakosha pakurapa kwepamusoro pepombi dzesimbi, yakakosha zvikuru pakuvandudza mashandiro epombi dzesimbi uye kuwedzera hupenyu hwesevhisi.

Kutanga, musimboti wesimbi pombi alkali washing process
Alkali washing, sezvinoreva zita racho, inzira yekuchenesa pamusoro pepombi dzesimbi uchishandisa alkaline solution. Munguva yekugeza alkali maitiro, iyo hydroxide ion (OH-) mune alkaline solution inopindirana nemakemikari netsvina yakaita semafuta emafuta uye maokisi ari pamusoro pepombi yesimbi, achiashandura kuita zvinhu zvinonyungudika mumvura, nekudaro achizadzisa chinangwa chekuchenesa. pamusoro. Panguva imwecheteyo, kugeza alkali kunogonawo kubvisa kusaenzana kusingaenzaniswi kwesimbi pombi pamusoro, zvichipa hwaro hwakanaka hwekuzovhara kunotevera kana anti-corrosion kurapwa.

Chechipiri, nhanho dzesimbi pombi alkali washing process
Iyo simbi pombi alkali washing process kazhinji inosanganisira anotevera matanho:
1. Pretreatment: Pamberi pekugezwa kwealkali, pombi yesimbi inoda kugadzirwa, kusanganisira kubvisa tsvina yakakura uye ngura pamusoro. Chinangwa chenhanho iyi kugadzira nzvimbo yekushanda yakachena yekugeza alkali uye kuvandudza maitiro ekugeza alkali.
2. Alkali solution kugadzirira: Zvinoenderana nezvinhu, mamiriro epamusoro, uye kuchenesa zvinodiwa zvepombi yesimbi, gadzirira mhinduro yealkaline yekusimbisa kwakakodzera. Yakanyanya kukwira kana yakaderera kuunganidzwa kwealkali mhinduro inokanganisira kuchenesa maitiro, saka inoda kunyatsodzorwa.
3. Alkali washing operation: Nyura iyo pretreated simbi pombi mumushonga wealkali kune imwe nguva kuitira kuti alkali solution igone kunyatsobata uye kuita nepamusoro pepombi yesimbi. Mukati mekuita uku, pombi yesimbi inoda kutenderedzwa nguva nenguva kuti ive nechokwadi chekuti zvikamu zvese zvasukwa zvakaenzana.
4. Kuchenesa uye kuomeswa: Mushure mokunge kushambidzwa kwealkali kwapera, pombi yesimbi inoda kushambidzwa nemvura yakachena kuti ibvise yakasara alkali solution uye reaction products. Mushure mekugeza, pombi yesimbi inoda kuomeswa kudzivirira kuparara kwechipiri kunokonzerwa nekusarira mwando.
5. Kuongororwa kwehutano: Pakupedzisira, pombi yesimbi mushure mekugeza alkali inoongororwa kuti ione kuti kuchena kwayo kwepamusoro, kupenya, nezvimwewo zvinosangana nezvinodiwa. Kana pane zvigadzirwa zvisina kukodzera, zvinofanirwa kuvandudzwa.

Chechitatu, iyo inoshanda mapoinzi esimbi pombi alkali yekuchenesa maitiro
Mukushanda chaiko, kuve nechokwadi chekuita uye kunaka kwesimbi pombi alkali yekuchenesa maitiro, zvinotevera pfungwa dzinofanirwa kucherechedzwa:
1. Sarudza iyo yakakodzera alkali mhinduro: Yakasiyana simbi pombi zvinhu uye pamusoro pemamiriro ezvinhu ane zvakasiyana zvinodiwa kune alkali mhinduro. Nokudaro, pakusarudza mhinduro yealkali, zvakakosha kunyatsofunga nezvemamiriro ezvinhu chaiwo epombi yesimbi uye kusarudza yakakodzera alkali mhinduro yemhando uye kuisa pfungwa.
2. Kudzora nguva yekuchenesa alkali: Nguva yakareba yekuchenesa alkali inogona kukonzera kuora kwakanyanya kwepombi yesimbi uye kukanganisa kushanda; nguva pfupi yakawandisa haigone kunyatsocheneswa. Naizvozvo, zvinodikanwa kuti utarise zvine musoro nguva yekuchenesa alkali zvichienderana nezvinhu zvakaita senge zvinhu uye dhigirii rekusvibiswa kwepamusoro pepombi yesimbi.
3. Chengetedza tembiricha yealkali solution: Munguva yekuchenesa alkali, tembiricha yakakodzera inogona kuwedzera kemikari yekuita chiyero, nekudaro ichivandudza kuchenesa. Nekudaro, tembiricha yakakwira zvakanyanya inogona kukonzera kuti alkali solution ibude nekukasira, zvichikanganisa maitiro ekuchenesa. Naizvozvo, tembiricha ye alkali solution inofanirwa kuchengetwa mukati memutsetse wakakodzera.
4. Gara uchitsiva iyo alkali solution: Sezvo kucheneswa kwealkali kuchienderera mberi, zvigadzirwa zvinoshanda mumushonga wealkali zvichapera zvishoma nezvishoma, uye humwe hutsvina huchaunganidza. Kuve nechokwadi chekuchenesa mhedzisiro, iyo alkali mhinduro inoda kutsiviwa nguva nenguva.
5. Matanho ekuchengetedza kuchengetedza: Alkali mhinduro inoparadza uye inogumbura kune imwe nhanho. Vashandi vanofanirwa kupfeka magirazi ekudzivirira, magirovhosi, uye zvimwe zvigadzirwa zvekudzivirira vashandi kuti vadzivise kusangana nemhinduro dzealkali. Panguva imwecheteyo, zvivakwa zvekufefetera zvinoda kugadzikwa panzvimbo yekugezesa alkali kuti kuderedze kukuvadza kwealkali solution volatilization kune vanoshanda.

Chechina, kukosha uye kukosha kwesimbi pombi alkali washing process
Sechinhu chakakosha pakugadzirwa kwepombi dzesimbi, iyo pombi yesimbi alkali washing process yakakosha zvikuru pakuvandudza kunaka kwepombi dzesimbi uye kuwedzera hupenyu hwavo hwebasa. Kuburikidza nealkali washing treatment, tsvina yakaita semafuta uye okisidhi pamusoro pemapombi esimbi inogona kubviswa zvinobudirira, uye hutsanana uye anti-corrosion performance yemapombi esimbi inogona kuvandudzwa. Panguva imwecheteyo, kugeza alkali kunogonawo kuvandudza microstructure yesimbi pombi pamusoro, ichipa hwaro hwakanaka hwekuzovhara kunotevera kana anti-corrosion kurapwa. Nokudaro, mukugadzirwa kwepombi yesimbi, kunyatsoteerera kunofanira kubhadharwa kune alkali washing link kuti ive nechokwadi chokuti hutano hwemapombi esimbi hunosangana nezvinodiwa.

Muchidimbu, nzira yekugeza alkali yemapombi esimbi inzira yakaoma uye yakatetepa, inoda kuti vashandisi vave neruzivo rwakapfuma rwehunyanzvi uye ruzivo runoshanda. Nekunzwisisa zvakadzama musimboti wekugezeswa kwealkali, kugona mapoinzi akakosha ekushanda uye kunyatsoita maitiro ekushanda, tinogona kuve nechokwadi chekuita uye kunaka kwesimbi pombi alkali washing process uye kupa vimbiso yakasimba yekushandiswa kunotevera kwepombi dzesimbi.
