Itekhnoloji yokutsha yeCatalytic njengenye yeenkqubo zokunyanga inkunkuma ye-VOCs, ngenxa yezinga eliphezulu lokucocwa, ubushushu obuphantsi bokutsha (<350 ° C), ukutsha ngaphandle komlilo ovulekileyo, akuyi kubakho ukungcola kwesibini njengesizukulwana se-NOx, ukhuseleko, ukugcinwa kwamandla kunye nokukhuselwa kwendalo kunye nezinye iimpawu, kwisicelo semarike yokukhusela indalo sinethemba lophuhliso oluhle.Njengekhonkco lobugcisa eliphambili lenkqubo yokutshisa i-catalytic, iteknoloji ye-catalyst synthesis kunye nemithetho yesicelo ibaluleke kakhulu.
1. Umgaqo we-catalytic combustion reaction
Umgaqo-nkqubo we-catalytic combustion reaction kukuba i-organic waste gas i-oxidized ngokupheleleyo kwaye ibolile phantsi kwesenzo se-catalyst kwiqondo lokushisa eliphantsi ukufezekisa injongo yokucoca igesi.Ukutsha kwe-Catalytic yindlela eqhelekileyo ye-gas-solid phase catalytic reaction, kwaye umgaqo wayo kukuba iintlobo ze-oksijini ezisebenzayo zithatha inxaxheba kwi-oxidation enzulu.
Kwinkqubo yokutshisa i-catalytic, umsebenzi we-catalyst kukunciphisa amandla okusebenza kokuphendula, ngelixa ii-molecule eziphendulayo zityetyiswa kwindawo ye-catalyst ukunyusa izinga lokuphendula.Ngoncedo lwe-catalyst, i-organic waste gas inokutshisa i-flameless kwiqondo lokushisa eliphantsi lokutshisa kwaye ikhulule ubushushu obukhulu ngelixa i-oxidizing kunye nokubola kwi-CO2 kunye ne-H2O.
3. Indima kunye nefuthe le-VOCs catalyst kwinkqubo yokutshisa i-catalytic
Ngokuqhelekileyo, iqondo lokushisa lokuzitshisa kwe-VOCs liphezulu, kwaye amandla okusebenza okutsha kwe-VOCs angancitshiswa ngokusebenza kwe-catalyst, ukwenzela ukunciphisa ukushisa komlilo, ukunciphisa ukusetyenziswa kwamandla kunye nokugcina iindleko.
Ukongeza, ukushisa okutshisayo jikelele (akukho catalyst ikhona) kuya kuba ngaphezu kwe-600 ° C, kwaye ukutshisa okunjalo kuya kuvelisa i-nitrogen oxides, ezihlala kuthiwa yi-NOx, ekwayinto engcolileyo ukuba ilawulwe ngokungqongqo.Ukutsha kwe-Catalytic kukutsha ngaphandle komlilo ovulekileyo, ngokubanzi ngaphantsi kwe-350 ° C, akuyi kubakho sizukulwana se-NOx, ngoko kukhuselekile kwaye kuhambelana nokusingqongileyo.
4. Yintoni isantya somoya?Zeziphi izinto ezichaphazela isantya somoya
Kwinkqubo ye-VOCs catalytic combustion, isantya sendawo yokusabela sihlala sibhekisa kwisantya sendawo yevolumu (GHSV), ebonisa amandla okusebenza kwe-catalyst: isantya sendawo yokusabela sibhekisa kubungakanani begesi ecutshungulwayo ngokweyunithi ngexesha leyunithi nganye yesixhobo. phantsi kweemeko ezithile, iyunithi yi-m³/(m³ catalyst •h), enokwenziwa lula njenge-h-1.Umzekelo, imveliso iphawulwe ngesantya sesithuba 30000h-1: oko kuthetha ukuba icubic catalyst nganye inokumelana ne-30000m³ yokukhupha igesi ngeyure.Isantya somoya sibonisa i-VOCs processing capability ye-catalyst, ngoko inxulumene ngokusondeleyo nokusebenza kwe-catalyst.
5. Ubudlelwane phakathi komthwalo wentsimbi exabisekileyo kunye nesantya somoya, ngaba umgangatho ophezulu wesinyithi oxabisekileyo ungcono?
Ukusebenza kwe-catalyst yensimbi exabisekileyo kuhambelana nomxholo wentsimbi exabisekileyo, ubungakanani beqhekeza kunye nokusabalalisa.Ngokufanelekileyo, isinyithi esixabisekileyo sichithwa kakhulu, kwaye isinyithi esixabisekileyo sikhoyo kwi-carrier kwiincinci ezincinci (ii-nanometers ezininzi) ngeli xesha, kwaye isinyithi esixabisekileyo sisetyenziselwa ubungakanani obukhulu, kunye nomthamo wokucubungula we-catalyst ngokuqinisekileyo. ehambelana nomxholo wentsimbi exabisekileyo.Nangona kunjalo, xa umxholo weentsimbi ezixabisekileyo uphezulu ukuya kuthi ga kwinqanaba elithile, amasuntswana esinyithi kulula ukuqokelela kwaye akhule abe ngamasuntswana amakhulu, indawo yokunxibelelana yentsimbi exabisekileyo kunye neeVOCs iyancipha, kwaye uninzi lwentsimbi ezixabisekileyo zisongelwe ngaphakathi, ngeli xesha, ukwandisa umxholo weentsimbi ezixabisekileyo akuncedi ekuphuculeni umsebenzi we-catalyst.
