Deaerator - chii? Types of mudziyo, kuti uchishandisa pfungwa

Boilers zvinowanzoitwa hwendarira. Kupfuura mvura therethrough marongerwo ane okisijeni uye carbon dioxide. Vaviri zvinhu izvi vane pamusoro simbi zvivako zviri bhaira zvikuru inokanganisa. Constant kuonana magasi aya vava vaizongoguma kutungamirira ayo rusting. deaerator - kuti kugadzirisa zvinhu uye achawedzera upenyu zvokushandisa, anokosha kugadzwa vanobatanidzwa mune chafariz bhaira zano. Chii? On ichi uye vanotaura gare gare munyaya ino.

tsananguro

Deaerator akadana midziyo inokosha chakagadzirirwa kubvisa okisijeni kubva coolant kudziyisa mugadziriro nokuda muchidziisa kukwira wokupedzisira chikepe. Saka, kuwedzera kune rokutsvaira basa, ichi mhando mano anoshanda sezvo kupisa. The chete setup inogona kushandiswa deaeration uye kudziyisa kurapwa sechinhu inotonhorera uye kuita-up mvura.

patani Features

The hama Kujeka design - ndizvo chinosiyanisa de-aerator. Chii tiri kuwana. Zvino ngationei kuti midziyo iyi hwakarongwa. Rinomirira bhaira deaerator tangi (BDA) pamwe akatasva pazvo wehunyambiri mbiru (KDA) akatasva pazvitsigiso. Rimwezve chinhu kwaiita michina chinhu hydraulic hurongwa inodzivirira kubva overpressure. Mbiru iri welded kuti tangi pasina flange - zvakananga.

On the chinjikira deaerator tangi vakatasva Inlet uye nzira yokubudisa kubatanidza svikiro dyisa zvinoyerera nemitsetse. Pazasi-vakatasva rinosakara. Chimwe chinhu akagadzira rinotarisirwa kuti kuunganidzwa degassed mvura yakaungana tangi. Riri pasi pasi BDA.

Hydraulic hurongwa michina yakadaro somunhu deaerator, chati iyo kunoratidzwa pazasi, yemanyorero panofanira maviri hydraulic nekiyi. Mumwe anodzivirira mudziyo upi kunyanyisa kumanikidzwa, uye wechipiri - kubva ngozi. Uyewo mune pakuvaka hydraulic ezvinhu rinosanganisira deaerator kuwedzera mutangi. Sasana zvokudya kubva deaerator kuti chinokosha coolant ane chinjikira humburumbira.

mbiru patani

Mbiru chinhu cylindrical goko pamwe pasi elliptical chimiro. Sezvaiitwa tangi, pamusoro payo pane kubatana romugove uye kubviswa svikiro. Inside mbiru dzinokosha mahwendefa yakabvooka kuburikidza nemvura dzapera. zvakagadzirwa Izvi zvinoita substantially kuwedzera nzvimbo kunyorerana yacho svikiro uye hwemvura, uye nokudaro kuti vakuchidzire pamwe kunonyanyisa nokukurumidza.

mhando midziyo

In boilers ano zvinogona kuiswa deaerator mvura:

• Vacuum;

• aspirated.

In wokutanga mhando deaerators kubviswa magasi anobudiswa kubva mvura vacuüm it. Kuvaka zvivako zvakadaro mamwe zvaisanganisira mvura-ndege kana hwemvura ejector. Yokupedzisira nokusunungura mapfundo mhando rinowanzoshandiswa imwe pakati kana yakaderera-simba bhaira enyika. Asi ejectors inokosha pombi zvinogona kushandiswa pave Vacuum. Vamwe kushaya michina yakadaro somunhu Vacuum degasser, ndiko kuti vakaroorana vanofanira kubviswa nechisimba, apo anoenda kunze mumhepo takasununguka - zvaoma.

Kunze mhando mbiri vakakurukura deaerator, bhaira anogona kuiswa munzvimbo pressurized mudziyo. Vanoshandira pa 0.6-0.8 MPa. Dzimwe nguva kupisa bhaira redunhu anosanganisirawo kumanikidzwa zvokushandisa yakaderera.

Makuriro Akaita kushandiswa

Uripiko de-aerator zvinogona kushandiswa? Chii, zvino munoziva. Sezvo mudziyo uyu rakagadzirirwa degassing ari kushanda svikiro, rinoshandiswa kureva apo pane midziyo kudziyisa yakagadzirwa simbi.

Kakawanda, de-aerators zvinoshandiswa kudziyisa mvura inopisa nehurongwa. Bhaira makamuri ane boilers kazhinji nepokuongorora Vacuum-mhando Kurongwa. Uyewo bleeders zvinogona kushandiswa zvirongwa zvakadaro ratinoona. Fitting pasi uye yakakwirira kumanikidzwa anechekuita dzimwe gadziriro dzakawanda kushanda nemhaka hwemvura bhaira. The siyana yokutanga (pa 0.025-0.2 MPa) akatasva mune injini kunyanya simba, rakagadzirirwa vashoma vatengi. Fitting kwakakwidziridzwa kumanikidzwa yaishandiswa chafariz nematunhu chete boilers, zvokudya guru kwazvo chiutsi.

Poppet degasser: oparesheni

Scheme gasi yokunatswa chaitwa mune mbiri-padanho deaerators: Blast (mu wechikamu) uye sefuro (ari tangi). Mukuwedzera, gadziriro iri kuitwa anyatsofukidzwa Inotubuka mudziyo. Mvura iri zvokudya kusvikira mbiru uko mhute riri kupatsanurwa. Uyezve, inoyerera pasi mukati tangi, izvozvo anodzokororwa imomo uye ari pauri kunyika hurongwa. pakutanga Steam zvokudya kupinda BDA. Mushure venting dzomunyika vhoriyamu inopinda mbiru. Achipfuura buri racho rouchenjeri tireyi, chiutsi rinopisa mvura saturation tembiricha.

Nenyunje kunobvisa mvura zvose kubva magasi. Panguva iyoyo hapana hwemvura condensation. marangwanda ayo hwakakanyiwa gasi kunokurumidziswa kubva svikiro uye asunungurwa kupinda kutonhora. The condensate kubva mhute iri asunungurwa kupinda abudise tangi. Munguva sedimentation mvura tangi residual duku gasi matema vape- pairi. Mvura kubviswa kuti ive mutangi. Dzimwe nguva chinjikira mudziyo kushandiswa chete yokugadzirisa. In zvivako zvakadaro, vaviri matanho degassing inoiswa mbiru.

Deaeration kuti maumbirwe mvura

mumwe kudziyisa hurongwa mvura circulates dzose. Asi uwandu kwayo pamusoro kwenguva, zvichiguma idonhe, achiri kunoderedza zvishoma nezvishoma. Saka, kuita-up mvura nechikoro kuti kudziyisa hurongwa. Sezvo mukuru izvozvo, aifanira chirongwa de-aeration. Pakutanga, mvura inoyerera kupinda hita, uye ipapo inopfuura nomunyika filters kwemakemikari acheneswe. Uyezve, sezvo zvinovaka muviri kuti anopinda deaerator shongwe. Vasunungurwa okisijeni mvura inoyerera kuti wedzera pombi. Last anoritungamirira kupinda yaunodya siyana kana kuchengetera tangi.

mushonga deaeration

Saka, mhinduro yomubvunzo wokuti chii deaerator bhaira iri nyore. midziyo iyi aiendeswa kufashaira mvura inopisa hwemvura kubvisa oxygen. Zvisinei, dzimwe nguva magasi kubva coolant mune miti yakadaro haina zvapera zvachose. Muchiitiko chino, nokuti mamwe yokuzvinatsa mvura bhaira inogona kuwedzerwa siyana reagents zvakagadzirirwa kusunga oxygen. Izvi zvingava Somuenzaniso, yavaibvisa sulfite. Panyaya iyi, nokuti Qualitative mvura deaeration kunoda kudziyisa kwayo. Zvikasadaro, makemikari zvakaitwa achava kunonoka. Uye kuwedzera okisijeni nokusungwa muitiro unogona kushandiswa nekuve catalysts. Dzimwe nguva mvura uye deaerated nokuisa kuburikidza ikanyanya pamusoro kwakajairika simbi Shavings. Wokupedzisira pane iyi vari kukurumidza oxidized.

hwakawanda Features

deaerator mudziyo hakuna kuoma. Zvisinei, kugadzwa kwayo kunofanira kuitwa pamwe pakuomerera kuchengeta zvose zvatinopiwa ruzivo. Kana kugadzwa midziyo yakadai vanotungamirirwa pakutanga kuda nayo nokuda mugadziri vanodhirowa uye bhaira chirongwa. Asati atanga installation, tarisa chokugadza rwakatanga apiwa mukova. The dzakaonekwa zvikanganiso zvinopedzwa. Chaizvoizvo iye nzira kugadzwa kunosanganisira anotevera:

• tangi akatasva pangoro;

• welded kwazviri rirege muromo;

• rezasi chikamu mbiru rwagurwa kunze dhayamita;

• wechikamu akatasva mota (mu iyi wakaiswa mukati ndiro rinofanira akaiswa yakatambarara);

• Mbiru iri welded kuti tangi;

• vakatasva unotonhorera mhute uye musungo mvura;

• maererano vanodhirowa vari unobatanidza pakutengeserana;

• kuisa nokukiya uye yokudzora mavharuvhu ;

• wakaitwa hydraulic bvunzo michina.

spraying kugadzwa

The pamusoro Magadzirirwo unonzi Belleville. Kunewo mwaya bleeders. Mano ichi mhando anoshandiswa zvishoma uyewo chinjikira chekuchengeta tangi guru chinzvimbo. Kusavapo yembiru - ndiko anoratidza munhu degasser. Zvingakubatsira kushanda zviri zvishoma yakasiyana. The chiutsi iri yaipiwa mu miti yakadaro kubva pazasi - kubva tangi rakamiswa ari muzinga chinjikira. Mudziyo pacharwo rakakamurwa kuva preheating mapazi uye deaeration. Bhaira chikafu mvura iri vaipa kune kamuri rokutanga riri pamusoro nebulizer. Pano, zviri nenharo kuti Kubika pfungwa uye runoyerera kupinda deaeration mapazi apo yakachena mhute kubviswa kwazviri.

Saka, ndizvo zvose kuti kunogona kutaurwa zano akadai deaerator. Chii, tinotarisira iwe kunzwisisa, nekuti hatina kupiwa mhinduro zvikuru hwakadzama mubvunzo uyu. Saka vanodana setup, ichipa kuramba ichishanda nemvura chiutsi inopisa boilers. Kusarudza mhando uye nzira kuisa midziyo rinoitwa zvinoenderana nokurondedzerwa ari kudziyisa michina uye bhaira chirongwa.
