Nhanganyaya uye Zvinhu zveSelective Catalytic Reduction (SCR) Catalysts
Selective catalytic reduction (SCR) catalysts inoshandisa chinoderedza kuita sarudzo neNOx muflue gasi, ichigadzira isiri{{0}chepfu uye kusvibisa{1}}isina N2 neH2O, pasi pechiito checatalyst.
Reaction tembiricha haingotaridzi chete chiyero chemaitiro ezvinoita asi zvakare kuita kweiyo SCR catalyst. Kazhinji, tembiricha yepamusoro inokonzeresa kukurumidza kuita maitiro uye yakakwirira catalyst chiitiko, zvichitungamira kune diki rekuita nzvimbo uye reactor vhoriyamu pane imwe unit nzvimbo. Tichifunga nezve reactant heat, system control, uye inokonzeresa tembiricha yakafanira, SCR system tembiricha inowanzoiswa pakati pe320 ne420 degree.
Space velocity ndiyo kiyi dhizaini dhizaini yekusarudza catalytic kuderedza (SCR) catalysts. Iyo inoyera nguva yekugara yeflue gasi (yakanyorova flue gasi pasi peyakajairwa mamiriro) mukati meiyo catalyst vhoriyamu, uye kune imwe nhanho inosarudza kana vanogadzirisa vanoita zvizere. Izvo zvakare zvinopesvedzera kukwenenzverwa kweiyo reactor catalyst framework uye friction kurasikirwa kweflue gasi.
Hunhu hwe flue gasi kuyerera pateni inogadzirisa kushanda kweiyo catalyst. Iyo yakakodzera flue gasi kuyerera pateni haingokwidzi mashandisirwo ekugadzirisa asi zvakare inoderedza kurasikirwa kwekukwenya. Mukugadzirwa kweinjiniya, iyo flue gasi inoyerera munda inofanira kunyatsotariswa. Ammonia jekiseni mapoinzi anofanirwa kuve nemamiriro ekusagadzikana kuti awane kusanganisa kwakaringana neflue gasi uye kugadzira inotsanangurwa zvakajeka homogeneous kuyerera dunhu.
