Indlela yokunciphisa i-Steam Boiler
Kunezindlela ezimbili eziyinhloko zokuqhumisa ama-boilers esitimu, okuyi-low blowdown kanye ne-blowdown eqhubekayo.Indlela yokukhipha imfucumfucu, inhloso yokukhipha indle kanye nokuqondiswa kokufakwa kokubili kuhlukile, futhi ngokuvamile azikwazi ukufaka esikhundleni somunye nomunye.
I-low blowdown, eyaziwa nangokuthi i-timed blowdown, iwukuvula i-valve enobubanzi obukhulu ezansi kubhayela imizuzwana embalwa ukuze ishaye phansi, ukuze inani elikhulu lamanzi ebhodweni kanye nentlenga kukhishwe ngaphansi kwesenzo sikabhayela. ingcindezi..Le ndlela iyindlela efanelekile ye-slagging, engahlukaniswa ngokulawula okwenziwa ngesandla kanye nokulawula okuzenzakalelayo.
I-blowdown eqhubekayo ibizwa nangokuthi i-surface blowdown.Ngokuvamile, i-valve isethwe ohlangothini lwe-boiler, futhi inani lokuthuthwa kwendle lilawulwa ngokulawula ukuvulwa kwe-valve, ngaleyo ndlela ilawula ukugxila kwe-TDS ezintweni eziqinile ezincibilika emanzini ku-boiler.
Kunezindlela eziningi zokulawula ukwehla kwebhoyili, kodwa into yokuqala okufanele icatshangelwe umgomo wethu oqondile.Enye iwukuba ukulawula ithrafikhi.Uma sesibale i-blowdown edingekayo kubhayela, kufanele sinikeze indlela yokulawula ukugeleza.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Imingcele esiyaziyo yilezi: ivolumu yokukhipha indle, ukucindezela kokusebenza kwe-boiler, ngaphansi kwezimo ezijwayelekile, ingcindezi engezansi yemishini yokukhipha indle ingaphansi kuka-0.5barg.Ngokusebenzisa le mingcele, usayizi we-orifice wokwenza umsebenzi ungabalwa.
Enye inkinga okufanele ibhekwe lapho kukhethwa imishini yokulawula i-blowdown ukulawula ukwehla kwengcindezi.Izinga lokushisa lamanzi akhishwe kubhayela yizinga lokushisa lokugcwala, futhi ukwehla kwengcindezi ku-orifice kuseduze nokucindezela kubhayela, okusho ukuthi ingxenye enkulu yamanzi izokhanya ibe isitimu sesibili, futhi umthamo wayo uzokwanda. izikhathi ezingu-1000.Umusi uhamba ngokushesha kunamanzi, futhi njengoba singekho isikhathi esanele sokuhlukana kwesitimu namanzi, amaconsi amanzi azophoqeleka ukuthi ahambe nesitimu ngesivinini esikhulu, okubangela ukuguguleka kwe-orifice plate, ngokuvamile ebizwa ngokuthi i-wire drawing.Umphumela uba i-orifice enkulu, ekhipha amanzi amaningi, futhi imoshe amandla.Ukuphakama kwengcindezi, kusobala kakhulu inkinga yesitimu sesibili.
Njengoba inani le-TDS litholwa ngezikhathi ezithile, ukuze kuqinisekiswe ukuthi inani le-TDS lamanzi abhayela phakathi kwezikhathi ezimbili zokutholwa liphansi kunevelu yethu eqondiwe yokulawula, ukuvulwa kwe-valve noma indawo yokuvula i-orifice kufanele inyuswe ukuze idlule umkhawulo wezinga eliphezulu. ukuhwamuka kwenani le-boiler yendle ekhishiwe.
Izinga likazwelonke le-GB1576-2001 libeka ukuthi kukhona ubudlelwano obuhambisanayo phakathi kokuqukethwe kukasawoti (ukugxila okuqinile okuncibilikisiwe) wamanzi abhayela kanye nokuhamba kukagesi.Ku-25 ° C, ukuqhutshwa kwamanzi esithandweni somlilo yi-0.7 izikhathi ze-TDS (okuqukethwe kukasawoti) wamanzi esithandweni.Ngakho-ke singakwazi ukulawula inani le-TDS ngokulawula i-conductivity.Ngokulawulwa kwesilawuli, i-valve yokudonsa ingavulwa njalo ukuze ishaye ipayipi ukuze amanzi abhayela ageleze ngenzwa ye-TDS, bese isignali yokuqhuba etholwe inzwa ye-TDS ifakwa kusilawuli se-TDS bese iqhathaniswa ne-TDS. isilawuli.Setha inani le-TDS ngemva kokubala, uma lingaphezulu kwenani elimisiwe, vula ivalvu yokulawula ye-TDS ukuze ushaye phansi, futhi uvale ivalvu kuze kube yilapho i-TDS yamanzi ebhayela etholiwe (okuqukethwe kukasawoti) ibe ngaphansi kwenani elimisiwe.
Ukuze ugweme imfucuza ye-blowdown, ikakhulukazi uma ibhayela ilindile noma ithwele umthwalo ophansi, isikhawu phakathi kokushaywa ngakunye sihlotshaniswa ngokuzenzakalela nomthwalo wesitimu ngokuthola isikhathi sokusha kukabhayela.Uma ingaphansi kwephoyinti elimisiwe, ivalve yokushaywa izovala ngemva kwesikhathi sokushaywa futhi ihlale injalo kuze kube yilapho ishaywa ngokulandelayo.
Ngenxa yokuthi uhlelo lokulawula i-TDS oluzenzakalelayo lunesikhathi esifushane sokuthola inani le-TDS lamanzi esithandweni futhi ukulawulwa kunembile, isilinganiso se-TDS samanzi esithandweni singaba eduze nenani eliphakeme elivumelekile.Lokhu akuvimbi nje kuphela ukungena kwesitimu nokuphuma amagwebu ngenxa yokugcwala kwe-TDS ephezulu, kodwa futhi kunciphisa ukushaywa kwamabhoyili futhi konga amandla.
