Marka laga hadlayo ka saarista boodhka warshadaha, "boorka shaandhada bacaha" maaha walax kiimiko gaar ah, laakiin waa erey guud oo loogu talagalay dhammaan walxaha adag ee ay qabato bacda shaandhada boodhka ee ku jirta bacda. Marka socodka hawada ee boodhka leh uu dhex maro bac shaandho dhululubo ah oo laga sameeyay polyester, PPS, fiber galaas ama fiber aramid xawaare dabaysha shaandhaynta ah oo ah 0.5–2.0 m/daqiiqo, boodhka waxaa lagu hayaa dusha sare ee derbiga bacda iyo daloolada gudaha sababtoo ah farsamooyin badan sida isku dhaca aan la taaban karin, baaritaanka, iyo nuugista elektrostatic-ka. Waqti ka dib, lakab ka mid ah boodhka shaandhada bacda oo leh "keega budada" sida xudunta ayaa la sameeyaa.
Sifooyinkaboorka shaandhada bacdaWaxaa soo saara warshado kala duwan si aad ah ayay u kala duwan yihiin: dambaska duulista ee ka yimaada kuleyliyeyaasha dhuxusha lagu shido waa cawl iyo wareegsan, oo leh cabbir walax ah oo ah 1-50 µm, oo ka kooban SiO₂ iyo Al₂O₃; boodhka foornada sibidhka waa alkaline waana mid si fudud loo nuugi karo qoyaanka iyo isku-darka; budada birta oksaydhka ee warshadaha birta waa mid adag oo xagal leh; boodhka lagu qabto warshadaha dawooyinka iyo cuntadana wuxuu noqon karaa daawooyin firfircoon ama walxo istaarij ah. Iska caabinta, qoyaanka, iyo gubashada boodhkan ayaa si kale u go'aamin doona xulashada bacaha shaandhada - daaweynta dusha sare ee ka hortagga-istaagga, dahaarka, saliidda u adkaysata iyo biyaha aan biyuhu gelin ama daaweynta dusha sare ee u adkaysata heerkulka sare, kuwaas oo dhammaantood ah inay ka dhigaan Bacda Shaandhada Boorka inay "qabsato" boodhkan si hufan oo ammaan ah.
Hadafka Bacda Shaandhaynta Boorka: ma aha oo kaliya "shaandhaynta"
U hoggaansanaanta qiiqa: Inta badan waddamada adduunka waxay qoreen xadka PM10, PM2.5 ama wadarta guud ee uruurinta boodhka si ay u dejiyaan xeerarka. Bacda Shaandhaynta Boorka oo si fiican loo qaabeeyey waxay yarayn kartaa boodhka soo galaya ee 10-50 g/Nm³ ilaa ≤10 mg/Nm³, taasoo hubinaysa in qiiqu uusan soo saarin "masduulaagyo jaalle ah".
Ilaali qalabka hoos yimaada: Dejinta shaandhooyinka bacaha ka hor inta aan la gelin hawada, marawaxadaha gaaska ama nidaamyada SCR denitrification waxay ka fogaan karaan xirashada boodhka, xannibaadda lakabka kiciyaha, waxayna dheereyn kartaa cimriga qalabka qaali ah.
Soo kabashada kheyraadka: Hawlaha sida dhalaalinta birta qaaliga ah, budada nadiifinta dhulka ee naadirka ah, iyo walxaha elektroodka lithium ee togan ee baytariga, boodhka shaandhada bacaha laftiisu waa badeeco qiimo sare leh. Boodhka waxaa laga qaadaa dusha sare ee bacda shaandhada iyadoo la adeegsanayo buufin garaaca ama gariir farsamo, ka dibna waxaa lagu celiyaa habka wax soo saarka iyada oo loo marayo mashiinka dambaska iyo qalabka lagu qaado boolal, iyadoo la ogaanayo "booska ilaa boodhka, dahabka ilaa dahabka".
Ilaalinta caafimaadka shaqada: Haddii heerka boodhka ee goobta shaqada uu ka badan yahay 1-3 mg/m³, shaqaaluhu waxay la kulmi doonaan pneumoconiosis haddii ay soo gaarto muddo dheer. Bacda Shaandhaynta Boorka ayaa ku xirta boodhka tuubada xiran iyo qolka bacaha, taasoo siinaysa shaqaalaha "gaashaam boodh" aan la arki karin.
Keydinta tamarta iyo hagaajinta habka: Dusha sare ee bacaha shaandhada casriga ah waxaa lagu daboolay xuub PTFE ah, kaas oo ilaalin kara marin hawo sare leh oo leh farqi cadaadis hoose (800-1200 Pa), isticmaalka awoodda marawaxaduna wuxuu hoos u dhacayaa 10%-30%; isla mar ahaantaana, calaamadda farqiga cadaadiska ee deggan waxaa lagu xiri karaa marawaxada soo noqnoqota ee isbeddelka leh iyo nidaamka nadiifinta boodhka caqliga leh si loo gaaro "ka saarista boodhka marka loo baahdo".
Laga bilaabo "dambas" ilaa "khasnad": qaddarka boodhka shaandhada bacaha
Qabashadu waa tallaabada ugu horreysa oo keliya, daawaynta xigtana waxay go'aamisaa masiirkeeda ugu dambeeya. Warshadaha sibidhka waxay dib ugu daraan boodhka foornada una beddelaan walxo ceeriin ah; warshadaha korontada ku shaqeeya ee kulaylka waxay u iibiyaan dambaska duqsiga dhirta isku darka shubka sidii isku-darka macdanta; kuwa birta dhalaaliya ee naadirka ah waxay u diraan boodhka bacaysan ee lagu hodanka yahay indium iyo germanium si ay u galaan aqoon-is-weydaarsiyada hydrometallurgical. Waxaa la dhihi karaa Bacda Shaandhaynta Boorka ma aha oo kaliya caqabad faybar ah, laakiin sidoo kale waa "kala-soocidda kheyraadka".
Boodhka shaandhada bacaha waa walxaha "la masaafuriyay" ee ku jira geeddi-socodka warshadaha, Bacda shaandhada boodhkana waa "ilaaliyaha" siiya nolol labaad. Iyada oo loo marayo qaab-dhismeedka faybarka ee quruxda badan, injineernimada dusha sare iyo nadiifinta caqliga leh, bacda shaandhada ma aha oo kaliya inay ilaaliso cirka buluugga ah iyo daruuraha cad, laakiin sidoo kale waxay ilaalisaa caafimaadka shaqaalaha iyo faa'iidada shirkadaha. Marka boodhku isu ururo dambas ka baxsan derbiga bacda oo dib loogu soo nooleeyo sidii kheyraad ku jira haamaha dambaska, waxaan si dhab ah u fahannay macnaha buuxa ee Bacda shaandhada boodhka: ma aha oo kaliya qayb shaandhayn ah, laakiin sidoo kale waa meesha laga bilaabayo dhaqaalaha wareegga ah.
