Steam Boiler Blowdown Method
Kune nzira mbiri huru dzekuvhuvhuta dzemabhoilers eutsi, dzinoti pasi kuvhuvhuta uye kuenderera kuvhuvhuta.Nzira yekuyerera kwetsvina, chinangwa chekubuda kwetsvina uye kuisirwa maitiro ezviviri zvakasiyana, uye kazhinji hazvigone kutsiva mumwe nemumwe.
Pazasi blowdown, inozivikanwawo sekuti timed blowdown, ndeyekuvhura hombe-diameter vharafu pazasi pebhailer kwemasekonzi mashoma kuti iputse pasi, kuitira kuti yakawanda yemvura yepoto uye sediment ibudiswe kunze pasi pechiito chebhailer. pressure..Iyi nzira ndiyo yakanakira slagging nzira, iyo inogona kukamurwa kuita manual control uye otomatiki kutonga.
Continuous blowdown inonziwo surface blowdown.Kazhinji, chivharo chinoiswa padivi rebhailer, uye huwandu hwetsvina hunodzorwa nekudzora kuvhurwa kwevhavha, nekudaro kudzora kusungirirwa kweTDS mumvura inonyungudika yakaoma yebhailer.
Kune nzira dzakawanda dzekudzora bhoiler kuvhuvhuta, asi chinhu chekutanga chinofanira kutariswa ndicho chinangwa chedu chaicho.Imwe ndeyekudzora traffic.Kana tangoverenga kuvhuvhuta kunodiwa kune bhailer, tinofanira kupa nzira yekudzora kuyerera.

Iwo maparamendi atinoziva ndeaya: vhoriyamu yekuyerera kwetsvina, boiler inoshanda kumanikidza, pasi pemamiriro akajairwa, kudzika kwemvura kumanikidzwa kwemidziyo yekuburitsa tsvina isingasviki 0.5barg.Uchishandisa aya ma parameter, saizi ye orifice yekuita basa inogona kuverengerwa.
Imwe nyaya inofanirwa kugadziriswa kana uchisarudza blowdown control mudziyo kudzora kudonha kwekumanikidza.Tembiricha yemvura inoburitswa kubva mubhailer ndiyo tembiricha yekuzara, uye kudonha kudonha kuburikidza neorifice iri padyo nekumanikidza mubhailer, zvinoreva kuti chikamu chikuru chemvura chinopenya mumhepo yechipiri, uye huwandu hwayo huchawedzera. ne1000 nguva.Utsi hunofamba nekukurumidza kupfuura mvura, uye sezvo pasina nguva yakakwana yekuti chiutsi nemvura zviparadzane, madonhwe emvura anomanikidzwa kufamba nemhepo nekumhanya kukuru, zvichikonzera kukukurwa kwegomba rehove, iro rinowanzonzi wire drawing.Mhedzisiro yacho ihombe hombe, iyo inodzinga mvura yakawanda, uye inopedza simba.Iyo yakanyanya kudzvanywa, iyo inonyanya kuoneka dambudziko rechipiri chiputi.
Sezvo kukosha kweTDS kuchionekwa pane dzimwe nguva, kuitira kuti tive nechokwadi chokuti kukosha kweTDS yemvura yebhailer pakati penguva mbiri yekuona yakaderera kudarika kukosha kwedu kwekutonga, kuvhurwa kwevhavha kana kuvhara kwegomba kunofanira kuwedzerwa kuti ipfuure. evaporation yebhailer huwandu hwetsvina yakaburitswa.
Chiyero chenyika GB1576-2001 chinotara kuti pane hukama hunoenderana pakati pemunyu (yakanyungudika yakasimba concentration) yeboiler mvura uye conductivity yemagetsi.Pa25 ° C, iyo conductivity yemvura yemoto ye neutralization ndeye 0.7 nguva TDS (munyu) yemvura yevira.Saka isu tinokwanisa kudzora kukosha kweTDS nekudzora conductivity.Kuburikidza nekutonga kwemutongi, iyo yekudhonza valve inogona kuvhurwa nguva nenguva kuti ibvise pombi kuitira kuti iyo boiler mvura ifambe neTDS sensor, uye ipapo iyo conductivity chiratidzo chinoonekwa neTDS sensor inoiswa kune TDS controller uye ichienzaniswa neTDS. controller.Seta kukosha kweTDS mushure mekuverenga, kana yakakwirira kudarika kukosha kweseti, vhura iyo TDS control valve ye blowdown, uye vhara vharafu kusvika yaonekwa bhailer mvura TDS (munyu wemukati) yakaderera pane yakatarwa kukosha.
Kuti udzivise kuvhuvhuta tsvina, kunyanya kana bhailer iri mukumira kana kuti yakaderera mutoro, nguva iri pakati pekutsvaira kwega kwega inobatanidzwa neatomuremu nekuona iyo boiler inopisa nguva.Kana pazasi penzvimbo yakatarwa, vharuvhu yekuvhuvhuta inovhara mushure menguva yekutsvaira uye irambe yakadaro kusvika pakudonha kunotevera.
Nekuti iyo otomatiki TDS control system ine nguva pfupi yekuona kukosha kweTDS kwechoto chemvura uye kutonga kwacho kwakaringana, muvhareji TDS kukosha kwemvura yevira inogona kuva pedyo nepamusoro inobvumirwa kukosha.Izvi hazvingodzivise kupinza uye kupupa furo nekuda kwekukwira kweTDS, asi zvakare kunoderedza kuvhuvhuta kweboiler uye kuchengetedza simba.
