Uthotho lwe-HGL kunye ne-HGW oluthe nkqo olukwinqanaba elinye kwayeiimpompo zeekhemikhali ezithe tye zesigaba esinyezisekelwe kwiimpompo zekhemikhali zokuqala zenkampani yethu. Siqwalasela ngokupheleleyo ubunyani beemfuno zesakhiwo seempompo zekhemikhali ngexesha lokusetyenziswa, sisebenzise amava aphambili esakhiwo ekhaya nakwamanye amazwe, kwaye samkela iimpompo ezahlukeneyo. umngxuma, isakhiwo sokudibanisa esibambekayo, esineempawu zesakhiwo esilula kakhulu, ukuqina okuphezulu, ukungcangcazela okuncinci, ukusetyenziswa okuthembekileyo, kunye nokugcinwa okulula. Sisizukulwana esitsha seempompo zekhemikhali zesigaba esinye eziphuhliswe ngobuchule.
Isicelo
Iimpompo zeekhemikhali ze-HGL kunye ne-HGW zothothoingasetyenziswa ukuya kuthi ga kwinqanaba elithile kushishino lweekhemikhali, ukuthuthwa kweoyile, ukutya, iziselo, amayeza, unyango lwamanzi, ukhuseleko lokusingqongileyo kunye nezinye ii-asidi, i-alkali, ityuwa kunye nezinye iindlela zokusetyenziswa ngokwemiqathango ethile yokusetyenziswa komsebenzisi. Isixhobo esinobuthi, esingenazo iinxalenye eziqinileyo okanye inani elincinci leenxalenye, kwaye sinobuthi obufana namanzi. Akukhuthazwa ukuba sisetyenziswe kwiimeko ezinobuthi, ezinokutsha, eziqhumayo, okanye ezinobungozi kakhulu.
(1) I-asidi ye-nitric kunye nokusetyenziswa kwayo kushishino lwe-asidi ye-nitric
Kwinkqubo yokuvelisa i-nitric acid nge-ammonia oxidation, i-dilute nitric acid (50-60%) eyenziwe kwi-stainless steel absorption tower iphuma ezantsi kwi-tower iye kwi-stainless steel storage tank, ize ithuthwe iye kwinkqubo elandelayo ngepompo ye-stainless steel. Nika ingqalelo kubushushu obuphakathi kunye noxinzelelo lokungena apha.
(2) Usetyenziso kwishishini le-phosphoric acid kunye ne-phosphoric acid
Kwi-asidi ecocekileyo, intsimbi engatyiwayo ye-Cr13 imelana ne-asidi edityanisiweyo enomoya kuphela, kwaye intsimbi engatyiwayo ye-chromium-nickel (Cr19Ni10) austenitic imelana ne-asidi edityanisiweyo enomoya kuphela. Eyona nto ilungileyo imelana ne-phosphoric acid yintsimbi engatyiwayo ye-chromium-nickel-molybdenum (ZG07Cr19Ni11Mo2), njl.
Nangona kunjalo, kwinkqubo yokuvelisa i-phosphoric acid, ukukhethwa kwezinto zepompo kunzima kakhulu ngenxa yeengxaki zokugqwala ezibangelwa bubukho bokungcola kwi-phosphoric acid, kwaye kufuneka kuphathwe ngononophelo.
(3) Ukusetyenziswa kwishishini le-sodium chloride kunye netyuwa (amanzi anetyuwa, amanzi olwandle, njl.njl.)
Intsimbi engagqwaliyo yeChromium-nickel inezinga eliphantsi kakhulu lokugqwala xa ithelekiswa nezisombululo zesodium chloride ezingathathi cala nezine-alkaline kancinci, amanzi olwandle kunye namanzi anetyuwa kubushushu obuthile kunye noxinzelelo, kwaye isetyenziswa kakhulu. Nangona kunjalo, kufuneka kuqatshelwe ukuba ukugqwala okuyingozi okufumaneka kwindawo ethile kunokwenzeka kwezinye iimeko.
Iimpompo zentsimbi engenasicizisetyenziswa kakhulu kwishishini lokutya ekuphatheni ityuwa kunye nokutya okunetyuwa. Nangona kunjalo, kufuneka kuqwalaselwe imiba ye-media crystallization kunye nemiba yokukhetha itywina ngoomatshini.
(4) Ukusetyenziswa kwishishini le-sodium hydroxide kunye ne-alkali
Intsimbi engagqwaliyo ye-Chromium-nickel austenitic inokumelana ne-sodium hydroxide ngaphantsi kwama-40-50% ukuya kuma-80°C, kodwa ayixhathisi kulwelo lwe-alkali oluxineneyo nolushushu kakhulu.
Intsimbi engatyiwayo yeChromium ifanelekile kuphela kwizisombululo ze-alkali ezinobushushu obuphantsi kunye noxinzelelo oluphantsi.
Ingqwalasela kufuneka inikwe kwingxaki ye-crystallization ephakathi.
(5) Ukusetyenziswa ekuthuthweni kweoyile
Kufuneka kuqwalaselwe ubungqingqwa besixhobo, ukukhethwa kweendawo zerabha, nokuba ingaba imoto inezinto ezithintela ukuqhuma, njl.
(6) Ukusetyenziswa kwishishini leyeza
Iimpompo zonyango zinokwahlulwa zibe ziindidi ezimbini ezilandelayo ngokwendlela yokuhambisa impompo:
Olunye uhlobo ziipompo zamanzi eziqhelekileyo, iipompo zamanzi ashushu kunye neepompo zenkqubo yokucoca amanzi amdaka ezisetyenziswa kwiiprojekthi zikawonke-wonke, kwaye olunye uhlobo ziipompo zokuthutha izinto ezifana nolwelo lweekhemikhali, izinto eziphakathi, amanzi acocekileyo, iiasidi kunye neealkali.
Eyokuqala ineemfuno eziphantsi zeempompo kwaye inokuphathwa ziimpompo ezisetyenziswa kwizixhobo zeekhemikhali ngokubanzi, ngelixa eyesibini ineemfuno eziphezulu zeempompo. Iimpompo kufuneka zihlangabezane neemfuno zobugcisa zeempompo ze-centrifugal ezisetyenziswa kwizixhobo zonyango.
(7) Ukusetyenziswa kwishishini lokutya neziselo
Kwishishini lokutya neziselo, le nto isetyenziswayo ayinakubanda okanye ayinakubanda kancinci, kodwa umhlwa awuvumelekanga, kwaye ubunyulu bayo buphezulu kakhulu. Kule meko, ipompo yentsimbi engagqwaliyo ingasetyenziswa.
Iimpawu zesakhiwo
