Deaerator - kuyini? Izinhlobo idivayisi, isimiso yokusebenza

Boilers ngokuvamile ezenziwe ngensimbi. Ukudlulisa amanzi therethrough e isakhiwo sinamandla umoya-mpilo ne-carbon dioxide. Zombili lezi zinto sigqoke izakhiwo zensimbi kubhayela nomthelela omubi kakhulu. Ukuthintana njalo lezi amagesi babé nakanjani kuholela ekutheni rusting yayo. deaerator - ukuze nginqande leso simo nokulondoloza ukuphila imishini, ukufakwa ekhethekile zifakwe ezishisayo kubhayela isikimu. Kuyini lokhu? Ngalolu futhi ngeke ukhulume kamuva kulesi sihloko.

definition

Deaerator ngokuthi imishini ekhethekile yakhelwe ukususa i-oksijini evela kokupholisayo Ukushisa izinhlelo nge ishisisa isikebhe sokugcina. Ngakho, ngaphezu yokuhlanza umsebenzi, lolu hlobo amadivayisi usebenze njengoba ukushisa. Ukusetha efanayo ingasetshenziswa deaeration bafudumale ukwelashwa njengoba izakhi namanzi ukwenza-up.

umklamo Izici

Ukuba lula eyisihlobo design - yilokho ehlukanisa de-aerator. Kuyini thina atholakala. Manje ake sibone indlela lokhu imishini luyatholakala. Limelela kubhayela deaerator tank (BDA) ne agibele amahhashi kwalo ikholomu mpo (KDA) ogibele izisekelo. Into eyengeziwe yalesi ngohlobo lomshini uhlelo wokubacindezela evikela ke kusukela overpressure. Ikholomu is eziphothene kuya ethangini ngaphandle flange - ngqo.

On the ovundlile deaerator ithangi sehlisiwe kunechweba kanye yokuveza ukuxhuma medium okuphakelayo kokukhwehlela imigqa. nokucwila Bottom-agibele amahhashi. Esinye isici se-design senzelwe ukuqoqwa degassed amanzi ukubuthwa ethangini. Itholakala ngaphansi phansi BDA.

Umfutholuketshezi uhlelo imishini efana deaerator, idayagramu zazo aboniswe ngezansi, ngokuvamile aqukethe sivala ezimbili wokubacindezela. Omunye ivikela idivayisi kusuka kunoma iyiphi ingcindezi ngokweqile, kanti owesibili - kusukela yingozi. Futhi ekwakhiweni kohlelo wokubacindezela kufaka deaerator ithangi ukunwetshwa. Shabalala fed kusukela deaerator a kokupholisayo ekhethekile kokuba isilinda ovundlile.

ikholomu design

Ikholomu kuyinto igobolondo cylindrical nge phansi ukuma okweqanda. Njengoba ethangini, kuso kukhona ukuxhumana nokulethwa kanye nokususwa medium. Ngaphakathi kukholamu kodwa amapuleti obukhethekile izimbobo lapho amanzi sihamba. Lo mklamo ivumela kakhulu ukwandisa endaweni contact medium and umusi, futhi kungakho ukufudumeza ngesivinini esiphezulu.

izinhlobo imishini

Ngo boilers yesimanje ingafakwa amanzi deaerator:

• cleaner;

• aspirated.

Esikhathini Uhlobo lokuqala deaerators ukususwa amagesi akhiqizwa namanzi vacuo. Ukwakhiwa kwezikhungo ezifana kuphinde kufakwe amanzi-jet noma isisi ejector. Imibuzo eyenza umuntu acabange kwamafindo elisetshenziswe kaningi umkhatsi noma ephansi amandla okokubilisa izinhlelo. Kunalokho ejectors amaphampu ekhethekile ingasetshenziswa ukwakha cleaner. Ezinye yokuntuleka imishini efana degasser cleaner, wukuthi imibhangqwana kudingeka zisuswe ngamandla, kuyilapho uyaphuma umkhathi ngendlela yemvelo - ngaphansi kwengcindezi.

Ngaphandle izinhlobo ezimbili okuxoxwe deaerator, kubhayela angase afakwe ku idivayisi Umfutho. Basebenta at 0.6-0.8 MPA. Ngezinye izikhathi ukushisa kubhayela wesifunda sihlanganisa ongaphakeme imishini ingcindezi.

Ububanzi bokusebenzisa

is the de-aerator ingasetshenziswa kuphi? Kuyini, manje uyazi. Njengoba kule divayisi yakhelwe degassing konemimoya ukusebenza, isetshenziswa ngokuyinhloko lapho kukhona imishini Ukushisa ezenziwe ngensimbi.

Ngokuvamile, de-aerators asetshenziswa Ukushisa namanzi ashisayo izinhlelo. Boiler amakamelo nge boilers kuvame ifakwe izilungiselelo cleaner-hlobo. Futhi bleeders ingasetshenziswa amaqhinga anjalo ozungeze umhlaba wethu. Onengqondo ingcindezi ongaphakeme kanye eliphezulu zisetshenziswa ngesikhathi izinhlelo kakhulu ezisebenza sibonga kubhayela umusi. Izinhlobonhlobo lokuqala (at 0.025-0.2 MPA) is shelwe izinjini hhayi enamandla kakhulu, yakhelwe inombolo encane abathengi. Onengqondo ingcindezi aphakeme elisetshenziswa izifunda ezishisayo kanye boilers, ukondla inqwaba umusi.

Poppet degasser: ukusebenza

Isikimu igesi uhlanzekile yaqaphela ezimbili-esiteji deaerators: Blast (e ikholomu) kanye bubble (ethangini). Ngaphezu kwalokho, uhlelo esitshalweni kwamanzi kudivayisi ogobhozayo. Amanzi sidla ikholomu lapho umusi kucubungula. Ngaphezu kwalokho, yiyo phansi ithangi, ke inakekelwa therein bese kukhishelwa emuva ohlelweni. Intuthu ekuqaleni kufakwa BDA. Ngemva kufuneka uveze ukukhungatheka ivolumu yangaphakathi lingena ikholomu. Kudlulwa emgodini ugqoko bubble, umusi heats emanzini ukuze saturation lokushisa.

Blasting ususa zonke amanzi kusukela amagesi. Ngesikhathi esifanayo kukhona umusi ukufingqa. izinsalela zayo ixubene igesi ukugqashuka kusukela medium and kukhishelwa endlini epholile. I condensate kusukela umusi kukhishelwa endlini ethangini amanzi. Phakathi sedimentation amanzi ethangini asalile igesi Bubbles ezincane ezatholakala kuwo. Amanzi asuswe ethangweni. Ngezinye izikhathi esitsheni ovundlile esetshenziswa kuphela zokuxazulula. Ngo ukufaka esinjalo, izinyathelo ezimbili degassing ezibekwe ikholomu.

Deaeration yamanzi ukwakheka

a amanzi bafudumale system ukhiphela ngokuqhubekayo. Kodwa inani ke ngokuhamba kwesikhathi, okuholela ukuvuza, namanje kancane kancane kunciphisa. Ngakho-ke, amanzi enze-up enikeziwe ohlelweni bafudumale. Njengoba main, ke kumelwe ibhekane inqubo de-aeration. Ekuqaleni, amanzi agelezela heater, bese sidlula izihlungi zokuhlanjululwa zamakhemikhali. Ngaphezu kwalokho, njengoba okunomsoco, lingena umbhoshongo deaerator. Esekhululiwe amanzi nomoya-mpilo ageleza eya futha umfutho. Kugcine oyiqondisayo phakathi ezininginingi eyanele noma ethangini USB.

chemical deaeration

Ngakho, impendulo yombuzo othi lokho kubhayela deaerator ilula. Lokhu imishini senzelwe amanzi abilayo nge umusi ashisayo ukususa umoya-mpilo. Nokho, ngezinye izikhathi amagesi kusukela kokupholisayo ezitshalweni esinjalo kusulwe ngokuphelele. Kulokhu, zokuhlanzwa okwengeziwe kubhayela amanzi kungenziwa wanezela izinhlobo ezihlukahlukene reagents yakhelwe ukuba ngibophe abanhliziyo-mpilo. Lokhu kungaba, isibonelo, i-sodium sulfite. Kulokhu, ngoba qualitative amanzi deaeration kudinga Ukushisa yayo. Kungenjalo, ukusabela chemical kuyoba kancane kakhulu. Futhi ukusheshisa oxygen ngibopha inqubo kungasetshenziswa izinhlobo ezahlukene yelikhono. Ngezinye izikhathi amanzi deaerated by edabula iphedi ezivamile metal shavings. I wokugcina Kulokhu ngokushesha oxidized.

Izici obandayo

kudivayisi deaerator akunzima kakhulu. Nokho, ukufakwa kwayo kumelwe kwenziwe nokugcina esiqinile wonke amalungiselelo ubuchwepheshe. Uma ufaka imishini enjalo ziqondiswa wokuqala nomkhulu kunabo bonke elikulo ngu imidwebo nomkhiqizi futhi kubhayela phrojekthi. Ngaphambi kokuqala ukufakwa, hlola ukufakwa futhi wenza yayo kabusha entry. I ukukhubazeka Kutholwe kuyaqedwa. Empeleni yena Inqubo yokufaka kuhilela izinyathelo ezilandelayo:

• tank ogibele isizinda;

• ashiselwe nalokho kuchichime itjhubhu;

• Ezansi kukholamu anqunywe phezu ububanzi ngaphandle;

• ikholomu ogibele tank (kuleli cala fixed ngaphakathi amapuleti kumele lumiswe nendawo);

• Ikholomu ashiselwe ukuba ithangi;

• sehlisiwe umusi cooler namanzi isicupho;

• ngokuhambisana imidwebo uxhuma imizila;

• setha uvala olawula valve ;

• ayeba wokubacindezela imishini yokuhlola.

ukufakwa sishaye

Umklamo ngenhla libizwa Belleville. Kukhona futhi fafaza bleeders. Amadivayisi zalolu hlobo zisetshenziswa ngaphansi futhi ovundlile isitoreji ithangi obunamandla. Ukungabikho amakholomu - ukuthi iyona eyenza a degasser. Umgomo we operation liphinde kancane ezahlukene. Isitimu ihlinzekwa ezitshalweni enjalo kusukela ngezansi - kusukela ithangi elisendaweni ikamu ovundlile. Isitsha ngokwayo sehlukaniswe indawo preheating futhi deaeration. Boiler amanzi okuphakelayo ihlinzekwa ukuba igumbi lokuqala itholakala phezu nebulizer. Lapha, kuba eliwu abilayo iphuzu bese ugelezela zone deaeration lapho umusi womoya-mpilo isuswe yilo.

Ngakho, yilokho kungathiwani sedivayisi ezifana deaerator. Kuyini, sithemba ukuthi uqonde, ngoba lokhu sikunike ngempela impendulo enemininingwane kulo mbuzo. Ngakho shayela isethaphu, ukuhlinzeka operation okuqhubekayo of hot water and umusi boilers. Kukhethwa izinhlobo nezindlela ukufakwa imishini wenziwa ngokuhambisana nezimiso imishini Ukushisa kubhayela phrojekthi.
