Nzira yekubvisa sei-non-condensable gasi semhepo kubva kune steam systems?

Iwo makuru masosi emagasi asina-condensable akadai semhepo ari muutsi masisitimu ndeaya anotevera:
(1) Mushure mekunge dhizaini yavharwa, vacuum inogadzirwa uye mweya unosvetwa mukati
(2) Boiler feed yemvura inotakura mweya
(3) Kugovera mvura uye mvura yakapfupikiswa zvinobata mhepo
(4) Kudyisa uye kurodha nzvimbo yepakati pemidziyo yekudziya

Non-condensable magasi anokuvadza zvakanyanya kune steam uye condensate systems
(1) Inogadzira kupisa kwekupisa, inokanganisa kuchinjisa kupisa, inoderedza kubuda kweanopisa kupisa, inowedzera kupisa nguva, uye inowedzera mhepo yekumanikidza zvinodiwa.
(2) Nekuda kwehurombo hwekupisa kwemhepo, kuvepo kwemhepo kunokonzeresa kupisa kusina kuenzana kwechigadzirwa.
(3) Sezvo tembiricha yemhepo mune isina-condensable gasi haigone kutariswa zvichienderana nekumanikidza gauge, izvi hazvigamuchirwe kune akawanda maitiro.
(4) NO2 uye C02 iri mumhepo inogona kuodza mavharuvhu nyore, zvinopisa kupisa, nezvimwe.
(5) Gasi risingapindiki rinopinda mugadziriro yemvura ye condensate inokonzera sando yemvura.
(6) Kuvapo kwemweya we20% munzvimbo yekudziya kuchaita kuti tembiricha yehutsi iderere nekupfuura 10°C. Kuti isangane nezvinodiwa tembiricha yeutsi, iyo steam pressure inodiwa inowedzerwa. Zvakare, kuvepo kwegasi risinga-condensable kuchaita kuti tembiricha yehutsi idonhe uye yakakomba yekuvhara mutsinga muhydrophobic system.

Pakati pematatu ekutamisa kupisa kwemafuta ekupikisa padivi remhepo - firimu remvura, firimu remhepo uye sikeri layer:

Kunyanya kupisa kwekupisa kunobva pamhepo. Kuvapo kwefirimu remhepo panzvimbo yekutsinhanisa kupisa kunogona kukonzera kutonhora, kana kuti zvakanyanya, kudzivirira zvachose kutamisa kupisa, kana kukonzeresa kusaenzana kupisa. Kutaura zvazviri, kupisa kwemhepo kunopesana ne1500 nguva yesimbi nesimbi, uye 1300 nguva yemhangura. Kana iyo yekuwedzera yemhepo chiyero munzvimbo yekupisa yekupisa inosvika 25%, tembiricha yemhepo inodonha zvakanyanya, nekudaro ichidzikisa kupisa kwekutamisa kushanda zvakanaka uye zvichitungamira mukutadza kubereka panguva yesterilization.

Naizvozvo, magasi asina-condensable muutsi system anofanira kubviswa nenguva. Iyo inonyanya kushandiswa thermostatic air exhaust valve pamusika parizvino ine bhegi rakavharwa rakazadzwa nemvura. Iyo yekubikira yemvura yakadzikira zvishoma pane saturation tembiricha yemhepo. Saka kana mhepo yakachena yakakomberedza bhegi rakavharwa, mvura yemukati inoputika uye kudzvinyirira kwayo kunoita kuti valve ivhare; kana muine mweya mumhepo, tembiricha yayo yakadzikira pane yakachena chiutsi, uye vharuvhu inovhurika otomatiki kuburitsa mweya. Kana iyo yakatenderedza iine tsvina yakachena, vharafu inovhara zvakare, uye iyo thermostatic exhaust valve inobvisa mweya chero nguva panguva yese yekushanda kweiyo steam system. Kubviswa kwemagasi asina-condensable kunogona kuvandudza kupisa kupisa, kuchengetedza simba uye kuwedzera kubereka. Panguva imwecheteyo, mhepo inobviswa munguva kuti ichengetedze kushanda kwemaitiro anokosha pakutonga kwekushisa, kuita kupisa yunifomu, nekuvandudza chigadzirwa chemhando. Deredza ngura uye mari yekugadzirisa. Kumhanyisa kumhanya kwekutanga kweiyo system uye kuderedza kushandiswa kwekutanga kwakakosha pakubvisa nzvimbo hombe yekudziya masisitimu.

Ivhavha yemhepo yemhepo yemhepo yemhepo inoiswa zvakanaka pakupera kwepombi, kona yakafa yemidziyo, kana nzvimbo yekuchengetedza yemidziyo yekutsinhanisa kupisa, iyo inobatsira kuunganidzwa uye kubviswa kwemagasi asina-condensable. . A manual ball valve inofanira kuiswa pamberi pe thermostatic exhaust valve kuitira kuti mhepo irege kumiswa panguva yekugadzirisa vharafu. Kana iyo steam system yakavharwa, valve yekupedza yakazaruka. Kana mhepo inoyerera ichida kuparadzaniswa kubva kune imwe nyika panguva yekuvhara, chidimbu chiduku chinodonha-soft-sealing check valve chinogona kuiswa pamberi pevhavha yekupedza.
