Mukutsvaga kugadzira simba rakachena, mafekitori emagetsi ari kuwedzera kushandisa matekinoroji epamusoro kuderedza kukanganisa kwaanoita nharaunda. Imwe yematekinoroji aya kushandisa masisitimu ekubvisa flue gas desulfurization (FGD), ayo anoita basa guru mukuderedza kuburitswa kwesulfur dioxide. Pakati pemasisitimu aya pane maFGD silicon carbide nozzles, ayo anogadzirwa nezvinhu zvechinyakare zvinonzi silicon carbide. Iri blog richaongorora kukosha kwemanozzles aya, shanduko dzemagadzirirwo awo, uye kukanganisa kwawo pakuchengetedza nharaunda.
Manotsi esilicon carbide akagadzirwa kuti abatsire mukubvisa sulfurization mumafekitori emagetsi. Basa rawo guru nderekubvisa sulfur dioxide (SO2) nezvimwe zvinokuvadza kubva mumagasi emvura anobuda panguva yekupiswa kwemafuta efossil, kunyanya marasha. Kukosha kwemaitiro aya hakugone kutaurwa zvakanyanya, sezvo sulfur dioxide iri iyo inonyanya kukonzera kusvibiswa kwemhepo nemvura ine acid, izvo zvinogona kukanganisa hutano hwevanhu nenharaunda. Nekushandisa manotsi esilicon carbide eFGD, mafekitori emagetsi anogona kuderedza kusvibiswa kwezvinhu uye kutevedzera mitemo yakasimba yezvakatipoteredza.
Magadzirirwo ema nozzles eFGD silicon carbide akagadzirwa kuti awedzere kushanda kwawo mumhando dzakasiyana-siyana. Mhando mbiri dze nozzles dzinoshandiswa mu desulfurization systems i spiral full cone nozzle uye vortex hollow cone nozzle. Spiral full cone nozzle yakagadzirirwa kugadzira mhute diki yemvura inonyungudutsa, iyo inowedzera kubatana kwemvura ne flue gas, nokudaro ichiwedzera kushanda kwe desulfurization process. Vortex hollow cone nozzle, kune rumwe rutivi, inogadzira pateni inotenderera inopfapfaidza iyo inogovanisa zviri nani absorbent, ichivimbisa kurapwa kwakakwana kwe flue gas. Kusarudzwa kwemhando idzi dze nozzle kunoenderana nezvinodiwa chaizvo zve power plant uye hunhu hwe flue gas iri kugadziriswa.
Chimwe chezvakanakira zvikuru zvesilicon carbide seFGD nozzle inyaya yekuti inogara kwenguva refu uye haiparare kana kupwanyika. Magetsi anowanzo shanda mumamiriro ezvinhu akaoma, tembiricha yakakwira uye zvinhu zvinogumbura zviri mugasi reflue. Magetsi eSilicon carbide anogona kutsungirira mamiriro ezvinhu akaoma aya, zvichiita kuti basa rive refu uye mari shoma yekugadzirisa ishandiswe. Kugara kwenguva refu uku hakungobatsiri chete pakushanda zvakanaka kwekubvisa sulfurization, asiwo kunobatsira kuvandudza kuvimbika kwemabasa emagetsi.
Pamusoro pekubviswa kwesimbi mumhepo, ma nozzles eFGD SiC anoitawo basa mukubvisa hunitrification uye guruva. Gasi remvura rinobva mumagetsi anofambiswa nemarasha harina sulfur dioxide chete, asiwo nitrogen oxides (NOx) uye tunhu tudiki. Nekubatanidza masisitimu eFGD netekinoroji yekubvisa hunitrification, mafekitori emagetsi anogona kurapa tsvina yakawanda panguva imwe chete, zvichiwedzera kuvandudza mhando yemhepo. Kukwanisa kugadzirisa hunitrification idzi kwakasiyana kwakakosha pakusangana nezvinodiwa zvakatipoteredza uye kuderedza huwandu hwecarbon mukugadzirwa kwesimba.
Kukanganiswa kwezvakatipoteredza nekushandisa maFGD silicon carbide nozzles kwakakura. Pasina desulfurization inoshanda uye denitrification, kuburitswa kwemhepo kubva mumagwenya emagetsi kunogona kukonzera kusvibiswa kwemhepo kwakanyanya, zvichikonzera zvirwere zvekufema uye kuora kwezvakatipoteredza. Pamusoro pezvo, kuburitswa kwemhepo kusina kusefa kubva kumagwenya emagetsi anopiswa nemarasha kunogona kukuvadza zvikamu zvemagwenya emagetsi anodziya mumagwenya emagetsi akabatanidzwa, zvichikonzera kugadziriswa kunodhura uye kusashanda zvakanaka. Nekudyara mari muhunyanzvi hwepamusoro hweFGD, magwenya emagetsi haangogone kuchengetedza nharaunda chete, asiwo kuvandudza mashandiro awo uye kugona kwawo hupfumi.
Sezvo mamiriro esimba pasi rose achiramba achichinja, kudiwa kwesimba rakachena uye rinogara kwenguva refu kuri kuramba kuchikurumidzira. Manotsi eFGD silicon carbide chikamu chakakosha chekuchinja kune kugadzirwa kwesimba rakasvibirira. Nekubvisa zvinobudirira tsvina inokuvadza kubva mumagasi emvura, manotsi aya anobatsira mafekitori emagetsi kusangana nezvinodiwa nemitemo uye kubatsira kupasi rine hutano. Sezvo tekinoroji ichifambira mberi uye kudiwa kwekuchengetedzwa kwezvakatipoteredza kuri kuramba kuchikura, basa remanotsi eFGD silicon carbide mukurwisa kusvibiswa kwemhepo nekushanduka kwemamiriro ekunze pasina mubvunzo richave rakakosha zvikuru.
Muchidimbu, FGD Silicon Carbide Nozzle chinhu chitsva chakakosha mumunda wekubvisa sarufa mumafekitori emagetsi. Dhizaini yayo yakasiyana, kugara kwenguva refu, uye kushanda kwayo mukubvisa sarufa dioxide nezvimwe zvinosvibisa zvinoita kuti ive chinhu chakakosha mukutsvaga kugadzirwa kwesimba rakachena. Sezvo mafekitori emagetsi achiramba achishandisa matekinoroji epamusoro ekuderedza kukanganisa kwawo zvakatipoteredza, kukosha kweFGD Silicon Carbide Nozzles kuchawedzera, zvichigadzira nzira yeramangwana rakasimba.
