Uma kubhekwa ukususwa kothuli lwezimboni, igama elithi "uthuli lwesihlungi sesikhwama" akuyona into ethile yamakhemikhali, kodwa igama elijwayelekile lazo zonke izinhlayiya eziqinile ezibanjwa yisikhwama sesihlungi sothuli endlini yesikhwama. Lapho umoya ogcwele uthuli udlula esikhwameni sesihlungi esiyisilinda esenziwe nge-polyester, i-PPS, i-fiber yengilazi noma i-aramid fiber ngesivinini somoya wokuhlunga esingu-0.5–2.0 m/min, uthuli lugcinwa ebusweni bodonga lwesikhwama nasema-pores angaphakathi ngenxa yezindlela eziningi ezifana nokushayisana kwe-inertial, ukuhlunga, kanye nokumuncwa kwe-electrostatic. Ngokuhamba kwesikhathi, kwakheka ungqimba lwesihlungi sesikhwama olune-"powder cake" njengengaphakathi.
Izakhiwo zeuthuli lwesihlungi sesikhwamaOkukhiqizwa yizimboni ezahlukene kuyahlukahluka kakhulu: umlotha ophuma kuma-boiler asebenza ngamalahle umpunga futhi uyindilinga, unosayizi wezinhlayiya ongu-1–50 µm, oqukethe i-SiO₂ kanye ne-Al₂O₃; uthuli lwesitofu sikasimende luyi-alkaline futhi kulula ukulumunca umswakama kanye ne-agglomerate; i-iron oxide powder embonini yensimbi iqinile futhi iyi-angular; kanti uthuli olubanjwe ezindaweni zokusebenzela zemithi nezokudla lungaba yimithi esebenzayo noma izinhlayiya zesitashi. Ukumelana, okuqukethwe komswakama, kanye nokusha kwalezi zinhlayiya kuzonquma ngokuphambene ukukhethwa kwezikhwama zokuhlunga - ukwelashwa komhlaba okumelana nokuma, okumbozwayo, okuvikela uwoyela kanye nokungangeni manzi noma okumelana nokushisa okuphezulu, konke okuhlose ukwenza i-Dust Filter Bag "yamukele" lezi zinhlayiya ngempumelelo nangokuphephile.
Umsebenzi wesikhwama sesihlungi sothuli: hhayi nje "ukuhlunga"
Ukuhambisana nokukhishwa komoya: Amazwe amaningi emhlabeni abhale imikhawulo yokugcwala kothuli ye-PM10, i-PM2.5 noma iyonke emithethweni. Isikhwama Sokuhlunga Uthuli esiklanywe kahle singanciphisa uthuli lokungena oluyi-10–50 g/Nm³ lube yi-≤10 mg/Nm³, okuqinisekisa ukuthi itshimini ayikhiphi "amadragoni aphuzi".
Vikela imishini engezansi komfula: Ukusetha izihlungi zezikhwama ngaphambi kokuhambisa nge-pneumatic, ama-gas turbine noma izinhlelo ze-SCR denitrification kungagwema ukuguguleka kothuli, ukuvaleka kwezingqimba ze-catalyst, nokwandisa impilo yemishini ebizayo.
Ukutholwa kwezinsizakusebenza: Ezinqubweni ezifana nokuncibilikisa insimbi eyigugu, i-rare earth polishing powder, kanye nezinto ze-electrode ze-lithium battery positive, uthuli lwesihlungi sesikhwama ngokwaso luwumkhiqizo onenani eliphezulu. Uthuli lususwa ebusweni besikhwama sesihlungi ngokufutha nge-pulse noma ngokudlidliza komshini, bese lubuyiselwa enqubweni yokukhiqiza nge-ash hopper kanye ne-screw conveyor, kutholakale "uthuli lube uthuli, igolide libe igolide".
Ukugcina impilo yomsebenzi: Uma izinga lothuli endaweni yokusebenzela lidlula u-1-3 mg/m³, abasebenzi bazohlushwa yi-pneumoconiosis uma bevezwa isikhathi eside. Isikhwama Sokuhlunga Uthuli sivala uthuli epayipini elivaliwe kanye negumbi lesikhwama, okuhlinzeka "ngesivikelo sothuli" esingabonakali kubasebenzi.
Ukonga amandla kanye nokwenza ngcono izinqubo: Ubuso bezikhwama zokuhlunga zesimanje bumbozwe nge-PTFE membrane, engagcina ukungena komoya okuphezulu ngomehluko ophansi wokucindezela (800-1200 Pa), futhi ukusetshenziswa kwamandla kwefeni kuncishiswa ngo-10%-30%; ngesikhathi esifanayo, isignali yomehluko wokucindezela ozinzile ingaxhunyaniswa nefeni yemvamisa eguquguqukayo kanye nohlelo lokuhlanza uthuli oluhlakaniphile ukuze kufezwe "ukususwa kothuli uma kudingeka".
Kusukela "kumlotha" kuya "emcebweni": isiphetho sothuli lwesihlungi sesikhwama
Ukubamba kuyisinyathelo sokuqala nje, futhi ukwelashwa okulandelayo kunquma isiphetho saso sokugcina. Izitshalo zikasimende zixuba uthuli lwe-oven zibe izinto zokusetshenziswa; izitshalo zamandla okushisa zithengisa umlotha wempukane ezitshalweni zokuxuba ukhonkolo njengezingxube zamaminerali; izinsimbi zokuncibilikisa insimbi ezingavamile zithumela uthuli olufakwe emasakeni olucebile nge-indium kanye ne-germanium ezindaweni zokusebenzela ze-hydrometallurgical. Kungashiwo ukuthi isikhwama se-Dust Filter asigcini nje ngokuba yisithiyo se-fiber, kodwa futhi "siyisihlungi sezinsiza".
Uthuli lwesihlungi sezikhwama luyizinhlayiya "ezidingisiwe" enkambisweni yezimboni, kanti isikhwama sesihlungi sothuli "singumgcini wesango" ozinika impilo yesibili. Ngesakhiwo esihle sefayibha, ubunjiniyela bendawo kanye nokuhlanza okuhlakaniphile, isikhwama sesihlungi asivikeli nje kuphela isibhakabhaka esiluhlaza okwesibhakabhaka namafu amhlophe, kodwa futhi sivikela impilo yabasebenzi kanye nenzuzo yezinkampani. Lapho uthuli luhlangana lube umlotha ngaphandle kodonga lwesikhwama futhi luvuswa njengomthombo ku-ash hopper, siyaqonda ngempela incazelo ephelele yesikhwama sesihlungi sothuli: akuyona nje into yesihlungi, kodwa futhi yindawo yokuqala yomnotho oyindilinga.
