Ithangi Lokupholisa Lesimo Esiphuthumayo Lesikhungo Sedatha: Izindlela Zokungafani Kanye Nengqondo Yokuvula
Ithangi lokupholisa lesimo esiphuthumayo lesikhungo sedatha ligcina amanzi abandayo agcina i-loop ingaphakathi kwebhendi yokushisa yayo ngenkathi isikhungo sishintsha kusuka kugridi kagesi kuya kugesi wejeneretha. Ingqondo yokuvula ibaluleke kakhulu kunomkhumbi: ukwehluleka kukagesi kuqala i-genset, ukudluliswa kwebhasi kuqinisekiswa ngaphambi kokuthi amaphampu aqale kabusha, futhi i-valve yokuhlukanisa ithangi ivuleka ngesikhathi esivunyelwe hhayi ngesikhathi esibekiwe. Ngaphandle kwalolo landelano, isitolo esilinganiswe kahle siphela ngemizuzu emibili yokuqala.
Ukwehluleka kokwehlisa izinga lokushisa ngendlela engaqondile kwenzeka ngezindlela ezingabalwa izibalo zokulinganisa usayizi. Isizinda singaba nama-feeder amabili, ama-chiller e-N+1, isethi yejeneretha, kanye nendawo yokugcina ebandayo evikelwe, kodwa sisengalahlekelwa izinga lokushisa ngesikhathi sokushintsha ngoba ivalvu ivulwe ngaphambi kokuba ibhasi linikwe amandla. Ithangi lokushisa eliphuthumayo lesikhungo sedatha lizosiza kuphela uma indlela esuka kugridi iya ethangini futhi ibuyele emthwalweni ichazwa, ixhunywe, futhi ihlolwe.
Umgomo ofanayo usuvele ulawula izitshalo zezinqubo: bamba umsebenzi obalulekile kuqala, bese ubuyisela ukusebenza kahle ngemuva. Ingxenye yokwelashwa kwe-anaerobic iqhutshwa ngale ndlela, igcina i-reactor izinzile ngenkathi imishini esizayo ibuyela. Okulandelayo kuhlanganisa izindlela ezine umjikelezo opholile ongazisebenzisa, ukulandelana kokudlulisa phakathi kwazo, izimvume kanye nokuphazamiseka okufanele kubhalwe ku-logic, kanye nendlela uchungechunge olufakazelwa ngayo.
Izindlela ezine umjikelezo opholile ongasebenza ngazo
Izitshalo eziningi zichaza izimo ezimbili, okujwayelekile kanye nesimo esiphuthumayo. Iluphu inezindlela zokudla ezine, futhi umqondo unquma ukuthi iyiphi ethwala umthwalo nganoma yisiphi isikhathi.
