Catalytic combustion tekinoroji seimwe yeVOCs tsvina gasi kurapwa maitiro, nekuda kweiyo yakanyanya kucheneswa mwero, yakaderera kupisa tembiricha (<350 ° C), kupisa pasina murazvo wakavhurika, hakuzovi nezvinosvibisa zvechipiri senge NOx chizvarwa, chengetedzo, kuchengetedza simba nekuchengetedzwa kwezvakatipoteredza uye humwe hunhu, mumusika wekuchengetedza nharaunda application ine tarisiro yakanaka yekusimudzira.Seyakakosha tekinoroji link yecatalytic combustion system, catalyst synthesis tekinoroji uye mitemo yekushandisa inonyanya kukosha.
1. Nheyo ye catalytic combustion reaction
Nheyo ye catalytic combustion reaction ndeyekuti iyo organic tsvina gasi yakanyungudika uye yakaora pasi pechiito checatalyst pane yakaderera tembiricha kuzadzisa chinangwa chekuchenesa gasi.Catalytic combustion yakajairika gasi-solid phase catalytic reaction, uye musimboti wayo ndewekuti reactive oxygen marudzi anotora chikamu mukudzika oxidation.
Mune inokonzeresa combustion process, basa reiyo catalyst ndere kudzikisa activation simba rekuita, nepo reactant mamorekuru anofumiswa pane inokonzeresa nzvimbo kuti awedzere chiyero chekuita.Nerubatsiro rwechidziviriro, iyo organic tsvina gasi inogona kupisa isina moto pane yakaderera kupisa tembiricha uye kuburitsa huwandu hukuru hwekupisa uku ichiwedzera oxidizing uye kuora mu CO2 neH2O.
3. Basa uye simba reVOCs catalyst mu catalytic combustion system
Kazhinji, tembiricha yekuzvitsvakira yeVOCs yakakwira, uye iyo activation simba yeVOCs kupisa inogona kudzikiswa kuburikidza neiyo activation yecatalyst, kuitira kuderedza kupisa kwekupisa, kuderedza kushandiswa kwesimba uye kuchengetedza mari.
Mukuwedzera, kupisa kwekushisa kwehuzhinji (hapana catalyst iripo) ichava pamusoro pe600 ° C, uye kupisa kwakadaro kunobudisa nitrogen oxides, iyo inowanzonzi NOx, iyo inosvibisa inofanira kudzorwa zvakasimba.Catalytic combustion ndeyekupisa pasina murazvo wakavhurika, kazhinji pasi pe350 ° C, hakuzove nechizvarwa cheNOx, saka yakachengeteka uye ine hushamwari hwakatipoteredza.
4. Chii chinonzi airspeed?Ndezvipi zvinhu zvinokanganisa airspeed
MuVOCs catalytic combustion system, iyo yekumhanyisa nzvimbo yekumhanyisa inowanzo inoreva vhoriyamu nzvimbo yekumhanya (GHSV), ichiratidza kugona kugadzirisa kwecatalyst: iyo reaction space yekumhanya inoreva huwandu hwegasi rinogadziriswa panguva yeyuniti pavhoriyamu yevhoriyamu. pasi pemamiriro akatarwa, iyo unit i m³/(m³ catalyst •h), inogona kurerutswa se h-1.Semuyenzaniso, chigadzirwa chakanyorwa nekumhanya kwenzvimbo 30000h-1: zvinoreva kuti cubic catalyst yega yega inogona kubata 30000m³ exhaust gasi paawa.Kumhanya kwemhepo kunoratidza iyo VOCs kugadzirisa kugona kweiyo catalyst, saka inowirirana zvakanyanya nekuita kweiyo catalyst.
5. Ukama huri pakati pesimbi yakakosha mutoro uye mhepo inomhanya, iyo yakakwirira yesimbi yakakosha zviri nani?
Kuita kweiyo yakakosha simbi catalyst kune hukama nezviri mukati mesimbi yakakosha, saizi yechidimbu uye kupararira.Nenzira yakanaka, simbi inokosha yakaparadzirwa zvikuru, uye simbi inokosha iripo pane inotakura muzvikamu zviduku zvikuru (nanometers dzakawanda) panguva ino, uye simbi inokosha inoshandiswa kusvika pamwero mukuru, uye kukwanisa kugadzirisa kwechigadziridzo kwakanaka. zvinoenderana nesimbi yakakosha.Nekudaro, kana zviri mukati mesimbi dzakakosha zvakakwirira kusvika padanho rakati, zvimedu zvesimbi zviri nyore kuunganidza uye kukura kuita zvidimbu zvakakura, nzvimbo yekubatana yesimbi yakakosha uye VOCs inodzikira, uye mazhinji ematare anokosha akaputirwa mukati, panguva ino, kuwedzera zvirimo zvesimbi dzakakosha hazvikodzeri kuvandudzwa kwebasa rinoita.
