Catalytic combustion tekinoroji
1 Technical Background
Kusimukira kwehupfumi nemagariro uye kudiwa kwemaindasitiri kunoita catalytic tekinoroji, kunyanya catalytic combustion tekinoroji, inowedzera kuve yakakosha maindasitiri tekinoroji nzira, uye nekuvandudzwa kwemararamiro evanhu uye kukura kwekudiwa, indasitiri inosimudzira icharamba ichipinda muzviuru zvemazana. mumhuri, muhupenyu hwevanhu. Chidzidzo chekupisa kwecatalytic chakatanga kubva pakuwanikwa kwecatalytic mhedzisiro yeplatinamu pakupisa kwemethane. Catalytic combustion inoita basa rakakosha mukuvandudza maitiro ekupisa, kudzikisa kupisa kwekuita, kukurudzira kupisa kwakakwana, uye kuvharidzira kuumbwa kwezvinhu zvine chepfu uye zvinokuvadza, uye yakashandiswa zvakanyanya muzvinhu zvakawanda zvekugadzirwa kwemaindasitiri uye hupenyu hwezuva nezuva.
2.Izvo zvakakosha uye zvakanakira catalytic combustion
Catalytic combustion ndeye yakajairwa gasi-yakasimba chikamu catalytic reaction, inoderedza activation simba rekuita nerubatsiro rwecatalyst, kuitira kuti ive inopisa isina murazvo pakupisa kwakadzika kwe200 ~ 300 ℃. Iyo oxidation ye organic matter inoitika pamusoro peiyo yakasimba catalyst, ichigadzira CO2 neH2O, uye ichiburitsa kupisa kwakawanda, nekuda kwekuderera kwayo oxidation reaction tembiricha. Naizvozvo, N2 mumhepo inodzivirirwa zvakanyanya kuita tembiricha yepamusoro NOx. Uyezve, nekuda kwekusarudzwa kwe catalysis ye catalyst, zvinokwanisika kudzikamisa oxidation process ye nitrogen-containing compounds (RNH) mumafuta, kuitira kuti vazhinji vavo vagadzire molecular nitrogen (N2).
Kuenzaniswa nekupisa kwechinyakare murazvo, kupisa kwecatalytic kune zvakanakira:
(1) Iyo tembiricha yekudzima yakadzikira, simba rekushandisa rakaderera, kupisa kuri nyore kugadzikana, uye kunyangwe iyo oxidation reaction inogona kupedzwa pasina kunze kwekutamisa kupisa mushure mekupisa kwekushisa.
(2) Kucheneswa kwepamusoro-soro, kuderera kwehuwandu hwehuwandu hwezvinosvibisa (zvakadai seNOx uye zvisina kukwana zvigadzirwa zvekupisa, nezvimwewo).
(3) Huru yeokisijeni yehuwandu, ruzha rwakaderera, hapana kusvibiswa kwechipiri, kupisa kuri pakati nepakati, mutengo wakaderera wekushandisa, uye manejimendi ekushanda.
3 Technology Application
Maitiro ekugadzirwa kwepetrochemical, pendi, electroplating, kudhinda, kupfekedza, kugadzira matayi uye mamwe maindasitiri zvese zvinosanganisira kushandiswa uye kuburitsa kweorganic volatile komisheni. Izvo zvinokuvadza zvinoputika organic compounds zvinowanzove hydrocarbon compounds, oksijeni-ine organic compounds, chlorine, sulfure, phosphorus uye halogen organic compounds. Kana aya ma organic compounds akaburitswa akananga mumhepo pasina kurapwa, anokonzeresa kusvibiswa kwezvakatipoteredza. Traditional organic tsvina gasi yekuchenesa nzira dzekurapa (sekunge adsorption, condensation, kunanga kupisa, nezvimwewo) zvine hurema, senge nyore kukonzera kusvibiswa kwechipiri. Kuti ukunde hurema hwechinyakare organic tsvina gasi nzira dzekurapa, catalytic combustion nzira inoshandiswa kuchenesa organic tsvina gasi.
Catalytic combustion nzira inoshanda uye yakapusa organic tsvina gasi yekuchenesa tekinoroji, tekinoroji ndiyo yakadzika oxidation yema organic molecules pamusoro peiyo catalyst kuita isingakuvadzi kabhoni dhaidhirodhi uye nzira yemvura, inozivikanwawo secatalytic yakakwana oxidation kana catalytic yakadzika oxidation nzira. kugadzirwa kunoenderana neiyo catalytic combustion tekinoroji yeindasitiri benzene tsvina gasi, iyo inoshandisa yakaderera-isina-yakakosha simbi catalyst, iyo inonyanya kuumbwa neCuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium uye cerium solid solution, iyo. inogona kuderedza zvakanyanya kudziya kwekushisa kwe catalytic combustion, kunatsiridza chiitiko checatalytic, uye kuwedzera zvakanyanya hupenyu hweiyo catalyst.Ichigadzirwa chine chekuita necatalytic combustion catalyst, inova inokonzeresa yekupisa inokonzeresa yekuchenesa organic gasi tsvina, uye inosanganisira. ye blocky honeycomb ceramic carrier skeleton, chifukidzo pairi uye inoyevedza simbi inoshanda chikamu. Iyo yekubatisa yecatalyst inoumbwa necomposite oxide inoumbwa neAl2O3, SiO2 uye imwe kana akati wandei alkaline pasi simbi oxides, saka ine yakanaka tembiricha. resistance. Izvo zvinoshanda zvikamu zvesimbi dzakakosha zvinotakurwa ne impregnation nzira, uye chiyero chekushandisa chinoshanda chakakwira.
