moralo Features

Tsela e bonolo le mong ka moralo - hore 's seo distinguishes ba de-aerator. ke eng e re fumanoa. Joale a re boneng hore na thepa ena e lokisetsa. Ho emela tanka deaerator tanka (BDA) le mounted hodima yona ka lenaneng la paatsepama (KDA) mounted ka litšehetsong. E elements eketsehileng tsa mofuta ona wa thepa e ka tsamaiso haeteroliki hore ho sireletsa e tsoa ho e overpressure. lenaneng la e welded ho tanka ntle flange - ka ho toba.

Ka tanka tshekaletseng deaerator mounted lesoba le le sehokelo ho hokahanya le mahareng fepa ka le lero mela. Tlase-mounted nwela. elements e 'ngoe ea ho rala le e reretsoe ya pokello ea degassed tanka ea metsi ho bokella. Ho e teng tlasa botlaaseng ba BDA.

tsamaiso e khopo haeteroliki thepa kang deaerator ka, setshwantshothalo ea eona e bontšitsoeng tlaase mona, ka tloaelo ho bopilwe liloko tse peli haeteroliki. E mong ho sireletsa sesebediswa khatello leha e le efe ka tsela e feteletseng, 'me ea bobeli - ho tloha kotsi. Hape ka kaho ea tsamaiso haeteroliki akarelletsa deaerator tanka katoloso ya. Mouoane fepa tloha deaerator le ho setsidifatsi khethehileng ba nang le cylindara tshekaletseng.

lenaneng la moralo

lenaneng la ke khetla cylindrical le tlase ya sebopeho elliptical. Jwalo ka tanka, ka ho na le maqhama 'bakeng sa phepelo le ho tloswa ea mahareng ka. Ka hare karolong e ngotsoeng e ba lipoleiti khethehileng le masoba ka eo metsi e ntse e feta. moralo Sena se nolofalletsa haholo eketsa sebaka sa ho ikopanya le ba mahareng le mouoane, 'me ka hona ho futhumatsa le lebelo lebetsoeng le.

mefuta ya thepa

Ka litanka morao-rao ka ho hlomamisa deaerator metsi:

• lephaka;

• aspirated.

Ka mofuta oa pele deaerators tlosa likhase hlahiswa ho tloha metsi ka vacuo. Kaho ea mehahong e joalo e ka ho eketsehileng e ne e akarelletsa le metsi-jete kapa mouoane ejector. Mofuta qetellang ea mafito sebediswa hangata ka ho fetisisa ka bohareng kapa tlaase-e leng matla a boiler tsamaiso ea. Ho ena le hoo ejectors lipompo khethehileng li ka sebelisoa ho bōpa e lephaka. Ba bang ba ho hloka thepa tse kang e lephaka degasser, ke hore banyalani ba lokela ho tlosoa tloha ka likhoka, ha a ntse a tsoela ka ntle ea sepakapaka e ka tsela tsa tlhaho - le tlas'a khatello.

Ntle ho mefuta e 'meli tšohloa deaerator, tanka ea metsi ka hlomamisa ka sesebediswa sa pressurized. Ba sebetsa ka 0.6-0.8 MPa. Ka linako tse ling mocheso o tanka oa potoloho e boetse e akarelletsa le thepa tlaase khatello.

Boholo ba tšebeliso

Moo e ka de-aerator ka sebelisoa? ke eng ho eona, hona joale u tseba. Ho tloha ka sesebelisoa sena se etselitsoe degassing e mahareng ho sebetsa, ho e sebediswa haholo-holo moo ho nang le futhumatsang lisebelisoa entsoe ka tšepe.

Hangata ka ho fetisisa, de-aerators li sebelisoa futhumatsang le metsi a chesang tsamaiso ea. Boiler likamore le litanka atisa ho a hlomelloa le Litlhophiso lephaka-mofuta itseng. Hape bleeders ka sebelisoa ka merero e joalo ea sepakapaka. Loketseng e tlase le phahameng khatello ea e sebelisoa ka tsamaiso ea ho fetisisa leboha ho sebetsa ho tanka ea mouoane. The tse fapa-fapaneng ea pele (ka ho le 0.025-0.2 MPa) e mounted ka dienjini e se e matla haholo, tse reretsoeng bakeng sa palo e fokolang ea bareki.

Poppet degasser: tshebetsong

Leqheka la tlhoekiso khase e hlokomela ka ba babeli-sethaleng deaerators: phatloha hoo (lenaneng a) le take bubble (ka tanka). Ho phaella moo, tsamaiso e lithuto koahetsoe phophoma sesebediswa. Metsi a fepa ho lenaneng la moo mouoane e ntse sebetswa. Ho ekelletsa moo, ho phalla fatše ka koloing, e ile a lula ho eona le e ka lokolloa khutlela ka tsamaiso ea. Steam qalong fepa ka BDA. Mora venting molumo ka hare ho kena lenaneng la ho. Ea fetang ka lesoba la floating woman take bubble, mouoane heats metsi ho ho tlala mocheso.

Ho qhomisa tlosa metsi tsohle ho tloha likhase ena. Ka nako e tšoanang na le mouoane condensation. mesaletsa lona tsoakane le khase le tseko ho tloha mahareng le e lokolloa ka batang ho. The condensate tloha mouoane e lokolloa ka tanka drainage. Nakong sedimentation ea metsi ka tanka barrel bubble nyane khase hlaha ho lona. Metsi tlosoa ho tanka kosimbaki.
