STET Triboelectrostatic-soociddiisa ayaa loo isticmaalaa beneficiation ganacsi of ash dhoobnayd sari dhuxusha in ay soo saaraan wax soo saarka carbon yar yahay isticmaalka bedelka cement ee la taaban karo ah ee ku dhow labaatan sanadood. Iyadoo 18 separators in 12 Quwadda dhuxul-rideen dunida oo dhan, ST Qalabka & Technology LLC ee (STET) xiranayo SEPARATOR electrostatic ayaa la isticmaalay si loo soo saaro ka badan 15 Milyan oo tan oo badeeco carbon hooseeyo.
Si aad u taariikhda, beneficiation ganacsi of ash dhoobnayd ayaa lagu sameeyaa si gaar ah on ash qalalan "orod saldhigga". technology beneficiation electrostatic STET ee yaraynaysaa content carbon of ash dhoobnayd dhuxul ah, soo saarka joogta ah, ash carbon yar yahay si loogu isticmaalo sida bedel ah cement. Duuli ash leh heerar carbon ilaa 25% ayaa la isticmaalaa si loo soo saaro ash la heer ah ay gacanta ku carbon ah 2 ± 0.5%. wax soo saarka carbon-hodan A waxaa isku mar soo saaro inuu ka soo kabsado qiimaha shidaalka ee carbon ah.
HORDHAC
American Dhuxul Ash Ururka (ACAA) sahan sanadlaha ah ee wax soo saarka iyo isticmaalka ash dhoobnayd dhuxusha ayaa sheegaya in inta u dhaxaysa 1966 iyo 2011, ka badan 2.3 bilyan oo tan gaaban ash dhoobnayd ayaa la soo saaray by boilers.1 utility dhuxul-rideen Of qadarka this, ku dhowaad 625 million tons ayaa beneficially isticmaalo, inta badan for cement iyo wax soo saarka la taaban karo. Si kastaba ha ahaatee, haray 1.7+ bilyan oo tan waxaa ugu horayn laga helaa meelha ama ka buuxsamay impoundments ponded. Inkasta oo heerka isticmaalka for ash dhoobnayd immika ahbaa ayaa aad u kordhay sannadihii la soo dhaafay, iyadoo heerarka hadda ku dhow 45%, ku dhowaad 40 million tons of ash dhoobnayd sii in lagu qubo ee sannad kasta. Inkasta oo heerka isticmaalka ee Europe ayaa u badan ka badan ee Maraykanka, Muga badan ee ash dhoobnayd ayaa sidoo kale lagu kaydiyaa meelha iyo impoundments in qaar ka mid ah dalalka Yurub. lacagta An-dhaafka ah ee carbon unburned ee ash dhoobnayd waa dhibaatada ugu badan. Ururka American ee State Highway iyo Gaadiidka Saraakiisha (XK ः in) iyo Heerarka Yurub (EN 450 Category A) waxay u baahan yihiin in cadadka carbon unburned ee ash dhoobnayd, qiyaasay by khasaaro on suuroggalaan (SHARCIGA) aan ka badnayn 5% miisaan. Si kastaba ha ahaatee, laga bilaabo bartamihii-1990, rakibidda qalabka xilsaaray gacanta NOx at dhirta tamarta dhuxusha-rasaas kor u carbon ah (SHARCIGA) content of badan oo ash ka caagan hore suuqa. shuruudaha dheeraad ah si loo yareeyo NOx iyo qiiqa kale warshad koronto ka dhashay in faddarada of ash dhoobnayd la ammonia. Taa awgeed, halka fahamka faa'iidooyinka la isticmaalayo ash dhoobnayd ee la taaban karo sii si loo kordhiyo, helitaanka ash dhoobnayd tayo ku haboon waa ay sii yaraanayaan. Geedi socodka si dhaqaale beneficiate off-tayo leh ash dhoobnayd waa sidaas oo kale ah oo sii kordhaya xiisaha ay u tamarta iyo warshadaha la taaban karo ee. STET waxay horseedday geedi socodka sida for carbon iyo ammonia ka saarida labada ka ash dhoobnayd.
TECHNOLOGY ARARTA - duuli Ash KALA Carbon
In SEPARATOR carbon STET ah (Jaantuska 1), wax la quudiyey galay farqiga khafiif ah inta u dhaxaysa labada electrodes planar isku midka ah. qayb ka yihiin triboelectrically Oogay interparticle
xiriirka. The carbon wanaagsan eedeeyay iyo macdanta xun eedeeyay (in ash immika ahbaa in aan la ilmadeeda oo la engejiyey) waxaa soo jiitay in electrodes soo horjeeda. qayb ka yihiin ka dibna isagoo xaaqan oo ay suunka dhaqaaqaan joogto ah iyo gaadhsiiyey jiho ka soo horjeeda. Suunka guuro qayb ka ku xiga si ay koronto kasta xagga ugu shishaysa soo horjeeda ee SEPARATOR ah. The xawaaraha suunka sare ayaa sidoo kale u saamaxaaya throughputs mid aad u sarreeya, ilaa 36 tan saacadiiba hal SEPARATOR a. Farqiga u yar, beerta danab sare, socodka countercurrent, ficil caro walxaha-walxaha iyo is-nadiifinta xorta ah ee suunka on electrodes waa sifooyinka muhiimka ah ee SEPARATOR STET ah. By gacanta beegyada uu nidaamka kala duwan, sida xawaaraha suunka, dhibic feed, iyo heerka feed, habka STET saarta ash dhoobnayd LOI hooseeyo ee ka kooban carbon ka yar 1.5 si ay u 4.5% ka dambas Daqsi feed ka bilowda in LOI ka 4% in ka badan 25%.
berdaha. 1 STET SEPARATOR
design SEPARATOR waa mid yara fudud oo is haysta. Mashiinka A loogu talagalay in lagu farsameeyo 36 tan saacaddii waa qiyaastii 9 m (30 ft.) dheer, 1.5 m (5 ft.) ballaaran, iyo 2.75 m (9 ft.) sare. The suunka iyo rollers la xiriira waa qaybo ka mid kaliya uusan u dhaqaaqin. electrodes waa taagan oo ka kooban qalab ah oo ku haboon raagaya. Suunka laga sameeyey caag nonconductive. isticmaalka awoodda SEPARATOR ee ku saabsan tahay 1 kilowatt-saac tonne ee wax baaraandegi leh ugu xoogga baabbi'iyey laba matoorrada wadista suunka.
Geedi socodka gebi ahaanba qalalan, wuxuu u baahan yahay ma qalab dheeraad ah oo kale oo aan ahayn ash dhoobnayd iyo saarta ma daata ama hawada qiiqa. The qalabka soo kabsaday ka kooban yihiin ash dhoobnayd hoos ku content carbon in heerka ku haboon in loo isticmaalo sida shaydi a pozzolanic ee la taaban karo, iyo jajab carbon sare waxtar leh sida shidaalka. Isticmaalka labada durdurrada wax soo saarka waxay bixisaa a 100% xal inuu u duulo dhibaatooyinka qubo ash.
