Deaerator - he aha te mea te reira? Momo o te pūrere, te parau tumu whakahaere

Nga kohua i Kei te nuinga o te wā hanga o te rino. Haere therethrough wai i roto i te hanganga he hāora me te hauhā. Rua o enei āhuatanga i runga i te hanganga whakarewa o te kōhua pānga tino kino. whakapā tamau ki enei haurehu kua heipü arahi ki tona rusting. deaerator - i roto i te tikanga ki te whakatika i te āhuatanga, me te roa te ora o te taputapu, kua ngā tāutatanga motuhake i roto i te kaupapa kōhua waiariki. He aha te mea te reira? I runga i tenei a ka kōrero i muri i roto i tenei tuhinga.

whakamāramatanga

ka karanga taputapu motuhake hangaia ki te tango hāora i te pūnaha coolant whakawera i te whakawera ake te waka whakamutunga Deaerator. Ko te kupu, i roto i te tua ki te mahi horoi, tenei momo o ngā pūrere mahi rite wera. Ka taea te whakamahi i te taua tatū mō deaeration me te maimoatanga whakawera rite te matūkai me te wai kia-ake.

Āhuatanga hoahoa

Ko te tapatahi whanaunga o te hoahoa - e te aha titore te de-aerator. He aha te mea te reira e kitea e matou. Na kia kite a pehea whakaritea tenei taputapu te. tohu te reira i kōhua tank deaerator (BDA) ki eke ki runga i te tīwae poutū (KDA) eke i runga i nga tautoko. He huānga atu o tenei momo o te taputapu ko te pūnaha waipēhi e tiaki ai i te overpressure. paiherea te tīwae te ki te tank, kahore flange - tika.

I runga i te tank deaerator whakapae eke matamata e me putanga ki te hono i te kai, me te rere ngā rārangi reo. piko Raro-eke. tikanga tētahi atu āhuatanga o te hoahoa kei te hoki te kohinga o degassed tank kohikohi wai. Kei raro i te raro o BDA.

pūnaha waipēhi taputapu pērā i te deaerator, he hoahoa o nei whakaaturia te raro nei, te nuinga ngā o rua raka waipēhi. tiaki tetahi i te pūrere i tetahi pēhanga nui, me te tuarua - i mōrearea. i roto i te hanga o te pūnaha waipēhi hoki ngā te deaerator tank roha. Whakaeto whangai i te deaerator ki te coolant motuhake he rango whakapae.

hoahoa tīwae

Ko te tīwae ko te anga porotakaroa ki te raro o te āhua porotītaha. Ka rite ki i roto i te tank, ki runga reira i reira he hononga mo te supply me tango o te reo. Roto te tīwae he papa paraharaha, motuhake ki rua i roto i nei te wai e tika. Tenei hoahoa taea whakanui i nui te wāhi o whakapā o te reo, me te mamaoa, a i konei ki te mahana i te tere mōrahi.

momo o te taputapu

I roto i te kohua i hou e taea te tāuta te wai deaerator:

• korehau;

• hā.

I roto i te momo tuatahi deaerators tango o ngā haurehu whakaputaina i te wai i roto i te vacuo. Ko te hanga o taua wāhi e ngā anō he wai-jet steam ejector ranei. Ko te ahua whakamutunga o knots whakamahia tino maha i roto i te pūnaha waenganui mana-iti kōhua ranei. Engari ejectors taea te whakamahi e papua motuhake ki te waihanga i tētahi korehau. Ētahi kore o te taputapu pērā i te degasser korehau, he e hiahia faaipoipo ki te nekehia atu i reira i te kaha, i te haere ia i roto i o te kōhauhau i roto i te ara tūturu - i raro i te pēhanga.

Haunga kōrero nga momo e rua deaerator, kia tāuta kōhua i roto i te pūrere pressurized. mahi ratou i 0.6-0.8 MPa. I te tahi taime ara iahiko kōhua wera hoki ngā te taputapu pēhanga iti.

Scope o te whakamahi

Kei hea te taea te whakamahi i te de-aerator? He aha te mea te reira, i teie nei e matau koutou. Mai te hangaia tenei pūrere mō degassing he reo mahi, kua whakamahia te reira matua wahi i reira ko te taputapu whakawera i hanga o te rino.

Nuinga o ngā wā, kei te whakamahia de-aerators i roto i ngā pūnaha whakawera me te wai wera. ruma kōhua ki nga kohua i e te nuinga o rite rawa ki te tautuhinga korehau-momo. taea hoki te whakamahi bleeders i roto i taua kaupapa kōhauhau. E tono pēhanga iti, me te tiketike tika i te nuinga o ngā pūnaha whakahaere whakawhetai ki te kōhua mamaoa. eke te momo tuatahi (i 0.025-0.2 MPa) Kei roto i te engines kore kaha rawa, hangaia hoki he maha iti o kiritaki. Tikanga pēhanga piki whakamahia i roto i iahiko waiariki ki nga kohua i, whangai i te rahinga nui o te korohū.

Poppet degasser: mahi

te kitenga o Scheme hau purenga te i roto i te rua-atamira deaerators: Blast (i roto i te pou) me te mirumiru (i roto i te tank). I tua atu, whakawhiti te pūnaha te pūrere koropupū ngaro. whangai Water te ki te tīwae te wahi e te tukatuka i te kohu. I tua atu, rere iho taua mea ki te tank, kua tonu reira ki reira, me te kua tukua hoki ki te pūnaha. Steam tuatahi whangai ki BDA. I muri pauroa mai te rōrahi ā-tomo te reira i te tīwae. E haere ana i te poka o te paepae mirumiru, heats mamaoa te wai ki te pāmahana waiwai.

te tango i ngingio wai katoa i te haurehu. I te wa ano i reira he steam tōhau. Ko tōna kōiwi i konatunatua ki te hau Nā i te reo, me te kua tukua ki te mātao. Kei te tukua te condensate i te kohu ki te tank waikeri. I roto i te te parataiao te wai i roto i te tank wäriu mirumiru hau iti puta i reira. nekehia Water ki te tank pupuri. I ētahi wā e whakamahia ana ipu whakapae anake hoki te whakatau. I roto i taua utanga, kua whakanohoia te kaupae degassing e rua i roto i te tīwae.

Deaeration o te wai āhua

honotanga he wai pūnaha whakawera tonu. Ko te nui o taua mea ki runga ki te wā, hua i roto i ngā turuturu, tonu āta heke. Na reira, te wai kia-ake tukua ki te pūnaha whakawera. Ka rite ki te matua, me waiho tena te tukanga o te de-aeration. I te tīmatanga, rere wai ki te whakamahana, a ka haere i roto i nga whiriwhiringa o te purenga matū. I tua atu, rite kai, tomo te reira i te pourewa deaerator. Wetekina i te wai hāora rere ki te papu whakanui. tataki whakamutunga reira ki te maha horomanga ranei i roto i te tank rokiroki.

deaeration matū

Ko te kupu, ko te kupu whakahoki ki te pātai o te mea te kōhua deaerator he ohie. tikanga tenei taputapu te hoki te wai kohua ki korohū wera ki te tango hāora. Heoi, i ētahi wā i te haurehu i te coolant i roto i taua tipu te kore tino murua. I roto i tenei take, mo te purenga atu taea te tāpiri i te kōhua wai ngā momo tauhohenga hangaia ki te here te hāora. kia tenei, hei tauira, te konutai sulfite. I roto i tenei take, mo te deaeration kounga wai titau tona whakawera. Kore, ka kia puhoi rawa te tauhohenga matū. A ki te whakatere taea te whakamahi i te tukanga here hāora ngā momo o kaiwhakakökï. I te tahi taime te wai, me te deaerated e haere i roto i te papa o shavings whakarewa tikanga. Ko te whakamutunga i roto i tenei take e tere oxidized.

Āhuatanga ekeeke

e kore he uaua rawa pūrere deaerator. Heoi, me kia kawea ona tāutanga i ki haapa'oraa tino o nga hangarau kai katoa. A, no te tāuta taua taputapu e arahina tuatahi me tuatahi piri ki reira e nga tuhi kaiwhakanao me te kaupapa kōhua. I mua i te tīmata te tāutanga, tirohia te tāutanga, me te hanga tona re-urunga. Kua whakakorea nga kohakore kitea. Mau ia tukanga tāutanga tā te whai i ēnei:

• tank eke i runga i te turanga;

• paiherea taua huri pupuha;

• te wahi o raro o te tīwae hatepea te atu i runga i te diameter waho;

• (Me tūnga i roto i tenei take i whakaritea i roto i te mau papaa parau huapae) he tīwae eke i runga i te tank;

• paiherea tīwae te ki te tank;

• eke kohu mātao me te mahanga wai;

• i roto i te runga i te tānga e tūhono ara;

• whakaturia maukati me te ture vaolo ;

• pūpuri taputapu whakamātautau waipēhi.

tāutanga riringi

huaina te hoahoa i runga ake te Belleville. He hoki rehu bleeders. Pūrere o tenei momo e whakamahia iti me hoki te rokiroki tank kaha nui whakapae. Ko te ngaro o tīwae - e ko te aha titore he degasser. Parau tumu o te mahi ko te iti rerekē hoki reira. tukua te mamaoa e i roto i taua otaota i raro - i te tank takoto i roto i te heru whakapae. Kei te wehea ipu iho ki te rohe preheating me deaeration. tukua kōhua wai whāngai te ki kei te wehenga tuatahi i runga i te tihi o te nebulizer. Here, he reira wera ki te wāhi e koropupu me rere ki te rohe deaeration te wahi nekehia atu te kohu hāora reira.

Na, e te katoa e taea te mea o te pūrere pērā i te deaerator. He aha te mea te reira, te ti'aturi nei matou matau koutou, no te mea kua hoatu e matou rawa te whakahoki taipitopito ki tenei pātai. Na karanga tatūnga, whakarato mahi tonu o te wai, me te mamaoa wera nga kohua i. kawea te kōwhiringa o te momo me ngā tikanga o te tāutanga o te taputapu i roto i roto i runga i te whakaritenga o te taputapu whakawera me kaupapa kōhua.
