Izingozi zemvelo zama-sand foundries
I-Sand foundry izodala izingozi ezihlukahlukene emvelweni ohlelweni lokukhiqiza, ikakhulukazi okuhlanganisa:
1. Ukungcoliswa komoya: Inqubo yokuphonsa izokhiqiza inani elikhulu lothuli namagesi ayingozi, njenge-carbon monoxide, i-nitrogen oxide, i-sulfide, njll., lezi zinto ezingcolisayo zizoba nomthelela omkhulu kukhwalithi yomoya ezungezile.
2. Ukungcoliswa kwamanzi: inqubo yokukhipha izokhiqiza amanzi angcolile, okuhlanganisa amanzi okupholisa, amanzi okuhlanza, amanzi angcolile okwelapha ngamakhemikhali, njll., lawa manzi angcolile uma ekhishwa ngokuqondile ngaphandle kokwelashwa, kuzodala ukungcola emzimbeni wamanzi.
3 Imfucuza eqinile: Inqubo yokulahla izokhiqiza imfucumfucu eqinile njengesihlabathi esilahlwayo, izinsimbi ezilahliwe kanye ne-slag, okuthi, uma ingalungiswa kahle, izothatha indawo enkulu futhi ibangele ukungcoliswa komhlaba namanzi angaphansi komhlaba.
4. Ukungcoliswa komsindo: ukusebenza kwemishini kanye nokuphathwa kwempahla ohlelweni lokuphonsa kuzokhipha umsindo, okuzodala ukungcoliswa komsindo endaweni ezungezile.
Isixazululo
Ukuze kuncishiswe ukulimala kwemvelo kwe-sand foundry, izinyathelo ezilandelayo zingathathwa:
1. Ukwelapha uthuli negesi eyingozi: uthuli olukhishwayo lungahlanzwa ngendlela emanzi noma eyomile, igesi eyingozi ingalawulwa ngokushintsha indlela yokushisa ye-carbon monoxide ne-nitrogen oxide emissions, ukusetshenziswa kwe-activated carbon, i-silica gel, i-alumina ecushiwe kanye nezinye i-adsorbants ukubhekana negesi yesulfure, i-hydrogen ku-chloride.
2. Ukwelashwa kwamanzi angcolile: Kumanzi angcolile akhiqizwa inqubo yokuphonsa, imvula, ukucwenga, ukuntanta komoya, ukujiya nezinye izindlela zingasetshenziswa ukususa izinto eziqinile ezimisiwe emanzini angcolile, futhi ukwelashwa kwe-aerobic oxidation kungasetshenziswa ukunciphisa isidingo samakhemikhali komoyampilo kanye nesidingo se-oksijini ye-biochemical emanzini angcolile.
3. Ukwelashwa kwemfucuza eqinile: isihlabathi semfucumfucu singaba yindawo yokulahla imfucumfucu ehlanzekile noma sisetshenziswe njengezinto ezixubene zezinto zokwakha, futhi i-slag ingaqoqwa futhi ithunyelwe ezitshalweni zikasimende ukuze zisetshenziswe njengezinto ezixubile.
4. Ukulawula umsindo: sebenzisa okokusebenza komsindo ophansi, okufana nesiphephetha-moya somsindo ophansi, futhi ufake kumshini wokukhipha umsindo noma usebenzise indlela yegumbi lokufakwa komsindo neshaneli yesifihli ukulawula umthombo womsindo.
5. Ukongiwa kwamandla kanye nokunciphisa ukungcola: ukuthuthukisa ukusebenza kahle kwamandla, ukunciphisa ukusetshenziswa kwamandla, ukunciphisa ukukhishwa kwe-carbon dioxide, nokusebenzisa amandla ahlanzekile kanye nobuchwepheshe bekhabhoni ephansi.
6. Ukuklama uhlelo lokuphathwa kwemvelo: ukusungula uhlelo lokuphatha imvelo ukuze kuqashwe futhi kuphathwe zonke izinhlobo zokungcola okukhiqizwa ohlelweni lokukhiqiza nokuqinisekisa ukuqaliswa okusebenzayo kwezinyathelo zokuvikela imvelo.
Ngokusebenzisa lezi zinyathelo, izikhungo zesihlabathi zinganciphisa kakhulu umthelela wazo omubi endaweni ezungezile futhi zizuze intuthuko esimeme.
