Kwimeko yokususwa kothuli lwemizi-mveliso, "uthuli lwe-bag filter" ayilonto ethile yekhemikhali, kodwa ligama eliqhelekileyo lazo zonke iisuntswana eziqinileyo ezithintelwe yingxowa ye-dust filter ekwi-baghouse. Xa ukuhamba komoya ogcwele uthuli kudlula kwingxowa ye-cylindrical filter eyenziwe nge-polyester, i-PPS, i-glass fiber okanye i-aramid fiber ngesantya somoya sokucoca esiyi-0.5–2.0 m/min, uthuli lugcinwa phezu kodonga lwengxowa nakwi-internal pores ngenxa yeendlela ezininzi ezifana nokungqubana kwe-inertial, ukuvavanya, kunye nokutsalwa kwe-electrostatic. Ekuhambeni kwexesha, umaleko we-bag filter dust ene-"powder cake" njengesiseko uyenziwa.
Iimpawu zeuthuli lwesihluzi sebhegieziveliswa ngamashishini ahlukeneyo zahlukile kakhulu: uthuthu oluvela kwiibhoyila ezisebenzisa amalahle lungwevu kwaye lungqukuva, lunobukhulu besuntswana eliyi-1–50 µm, oluqulathe i-SiO₂ kunye ne-Al₂O₃; uthuli lwe-oven yesamente luyi-alkaline kwaye kulula ukulufunxa umswakama kunye ne-agglomerate; umgubo we-iron oxide kushishino lwe-metallurgical uqinile kwaye une-engile; kwaye uthuli olubanjwe kwiindawo zokusebenzela amayeza nokutya lunokuba ngamayeza asebenzayo okanye amasuntswana e-starch. Ukumelana, umxholo womswakama, kunye nokutsha kwezi nthuli kuya kugqiba ngokutshintsha ukhetho lweengxowa zokucoca - ezichasene ne-static, ezigqumayo, ezingangeni mafutha kwaye zingangeni manzi okanye ezimelana nobushushu obuphezulu, zonke ezi zenzelwe ukwenza iNgxowa yokucoca uthuli "imkele" olu thuli ngokufanelekileyo nangokukhuselekileyo.
Umsebenzi wengxowa yesihluzi sothuli: kungekuphela nje "kokucoca"
Ukuthobela ukukhutshwa komoya: Amazwe amaninzi ehlabathini abhale imida yoxinzelelo lothuli olupheleleyo kwi-PM10, PM2.5 okanye kwimithetho. Ingxowa yesihluzi sothuli eyilwe kakuhle inganciphisa uthuli olungena kwi-10–50 g/Nm³ ukuya kwi-≤10 mg/Nm³, ukuqinisekisa ukuba itshimini ayikhuphi "iidragoni ezityheli".
Khusela izixhobo ezisezantsi: Ukuseta izihluzi zeengxowa ngaphambi kokuba kuhanjiswe umoya, ii-turbine zegesi okanye iinkqubo ze-SCR denitrification kunokuthintela ukuguguleka kothuli, ukuvaleka kwee-catalyst layers, kunye nokwandisa ubomi bezixhobo ezibizayo.
Ukufunyanwa kwezixhobo: Kwiinkqubo ezinje ngokunyibilikisa isinyithi esixabisekileyo, umgubo wokupolisha umhlaba onqabileyo, kunye nezixhobo ze-electrode ze-lithium battery positive, uthuli lwesihluzo sebhegi ngokwalo luyimveliso exabisekileyo. Uthuli lususwa kumphezulu wengxowa yesihluzo ngokutshiza nge-pulse okanye ngokungcangcazela koomatshini, luze lubuyiselwe kwinkqubo yemveliso nge-ash hopper kunye ne-screw conveyor, kufezekiswa "uthuli lube luthuli, igolide ibe yigolide".
Ukugcina impilo yomsebenzi: Ukuba ubuninzi bothuli kwindawo yokusebenzela budlula i-1-3 mg/m³, abasebenzi baya kuhlaselwa yi-pneumoconiosis ukuba bavezwa ixesha elide. Ingxowa yesihluzi sothuli ivala uthuli kumbhobho ovaliweyo kunye negumbi leengxowa, inika "isikhuselo sothuli" esingabonakaliyo kubasebenzi.
Ukonga amandla kunye nokwenza ngcono inkqubo: Umphezulu weengxowa zesihluzo zanamhlanje ugqunywe yi-PTFE membrane, enokugcina umoya ungena ngamandla kumahluko ophantsi woxinzelelo (800-1200 Pa), kwaye ukusetyenziswa kwamandla kwefeni kuncitshiswa nge-10%-30%; kwangaxeshanye, isignali yomahluko woxinzelelo oluzinzileyo inokunxulunyaniswa nefeni yefrikhwensi eguquguqukayo kunye nenkqubo yokucoca uthuli ekrelekrele ukuze kufezekiswe "ukususwa kothuli xa kuyimfuneko".
Ukusuka "kumlotha" ukuya "kubutyebi": isiphelo sothuli lwesihluzo seengxowa
Ukubanjwa linyathelo lokuqala kuphela, kwaye unyango olulandelayo lugqiba isiphelo salo sokugqibela. Izityalo zesamente zixuba uthuli lwe-oven zibe zizinto eziluhlaza; izityalo zamandla obushushu zithengisa uthuthu oluphaphazelayo kwizityalo zokuxuba i-concrete njengezinto ezixutyiweyo zezimbiwa; abanyibilikisi besinyithi abanqabileyo bathumela uthuli olufakwe kwiingxowa olutyebiswe nge-indium kunye ne-germanium kwiindawo zokusebenzela ze-hydrometallurgical. Kunokuthiwa iNgxowa yesihluzi soDust ayisiyo nje kuphela isithintelo sefayibha, kodwa ikwayi "resource sorter".
Uthuli lwezihluzo zebhegi ngamasuntswana "agxothiweyo" kwinkqubo yemizi-mveliso, kwaye iNgxowa yeZihluzo zoDust "ngumlindi-sango" obanika ubomi besibini. Ngolwakhiwo oluhle lwefayibha, ubunjineli bomphezulu kunye nokucoca ngobuchule, ingxowa yesihluzo ayikhuseli nje kuphela isibhakabhaka esiluhlaza kunye namafu amhlophe, kodwa ikwakhusela nempilo yabasebenzi kunye neenzuzo zeenkampani. Xa uthuli lujika lube luthuthu ngaphandle kodonga lwengxowa kwaye luvuselelwa njengomthombo kwi-ash hopper, siyiqonda ngokwenene intsingiselo epheleleyo yeNgxowa yeZihluzo zoDust: ayisiyonto yokucoca kuphela, kodwa ikwayindawo yokuqala yoqoqosho olujikelezayo.
