Manotsi eFGD Silicon carbide sprial – FGD neAmmonia
Masisitimu ekubvisa sulfurization yegesi (FGD) anoshandisa lime kana limestone semakemikari anoshandiswa zvakanyanya pasi rese kudzora kuburitswa kweSO2 pamagetsi anoshandiswa nemalahle. Zvisinei, masisitimu akavakirwa paAmmonia ari kubuda senzira inoshanda yekugadzirisa zvipingamupinyi zvine chekuita nekugadzirwa uye kushandiswa kwemarara emvura uye akasimba. Tekinoroji yekubvisa sulfurization inoshanda neAmmonia (EADS) haigadzire matsime emvura kana zvigadzirwa zvisina kunaka zvinoda kuraswa; asi, maitiro ekuvhara anogadzira chinhu chimwe chete chinogadziriswa neammonium sulfate fertilizer chinogona kusaraswa chinogona kuderedza anopfuura 50 muzana yemutengo wekushanda.

Kucheneswa kwegasi remvura inoyerera nekushandisa lime suspension
Kana gasi remvura richibviswa sulphur mumvura, rinopfuudzwa nemuchina unobvisa sulphur mumvura (scrubber). Mudziyo we lime unowanikwa mumuchina unobvisa sulphur (mukaka we limestone kana lime) unoshanda pamwe chete ne sulfur dioxide kubva mugasi remvura. Kana huwandu hwemvura hukafambiswa zvakanaka, ndipo panoshandawo desulphurization.
Panguva imwe chete nekunyudzwa kwemvura, gasi rinoyerera rinozara neutsi hwemvura. Rinonzi "gasi rakachena" rinowanzoburitswa kuburikidza nechimney chakanyorova kana shongwe yekutonhodza. Mvura inorasika nekudaro inofanira kutsiviwa. Lime slurry inopombwa muropa inochengetwa ichishanda nemakemikari nekuramba ichidurura mvura yakawandisa uye kuitsiva ne reactive suspension itsva. Mvura inoyerera ine gypsum, iyo - yakapfava - chigadzirwa che reaction ye lime ne sulphur uye inogona kutengeswa mushure mekubviswa mvura (semuenzaniso madziro e gypsum muindasitiri yekuvaka).
Manotsi eceramic akakosha anoshandiswa kupinza lime suspension mu absorber. Manotsi aya anoumba madonhwe madiki akawanda kubva mu pomped suspension uye nokudaro nzvimbo yakakura ye reaction kuti ifambiswe zvakanaka. Zvinhu zveceramic zvinobvumira hupenyu hurefu hwekushanda kunyangwe lime suspension ine gypsum content ine hunhu hwekukwesha. Mukugadzira kwedu tinokoshesa zvikuru zvikamu zvakasununguka, kuitira kuti tsvina diki mu suspension isagone kuisa ma notsi. Kuti ishande zvishoma, ma notsi aya anogona kugadziriswa kuti ashande zvakanaka papombi. Notsi inogona kutsanangurwa (inenge) yega yega process engineering challenge. Kuwedzera kune ma notsi e full-cone ne hollow-cone mu spray angles dzakasiyana uye flow rates, ZPC nozzle ine patent twist compensation inowanikwawo.
Nzvimbo yekunyudza ine mazinga akasiyana-siyana ema nozzles uye sisitimu yekuparadzanisa madonhwe yakaiswa yakatwasuka, kuitira kuti madonhwe akanaka anotakurwa murwizi rwegasi adzoke mukuita kwayo. Nemadonhwe edu ekuparadzanisa ane simba repamusoro unogona kuwedzera kushanda zvakanaka kwefekitari yako.
Zvinhu zvakasimba zviri mu suspension zvinogona kukonzera kuparadzwa, semuenzaniso mu droplet separator, mu inlet duct kana pamapaipi, izvo zvinogona kukonzera matambudziko mukushanda. Sezvo mvura ichigara ichibviswa kubva mu circuit kuburikidza ne evaporation, mvura inofanira kuiswa mu absorber, iyo inogona uye inofanira kushandiswa pakuchenesa. ZPC tongue nozzles dzakaratidza kuti dzinochenesa flue gas inlet. ZPC full cone nozzles dzinowanzo shandiswa pakuchenesa ma droplet separator.
Mapurasitiki (semuenzaniso emapaipi) nerabha (semuenzaniso magasket, rabha linings, nezvimwewo) anowanzo shandiswa muchinhu chinonyudza mvura chine simba rekudzivirira kupisa rakaderera pane tembiricha yemhepo isina kutonhora. Kazhinji, suspension inopombwa mucircuit inotonhodza mweya wemvura zvakakwana, asi kana, semuenzaniso, pombi yekudyisa yakamiswa, mapurasitiki nemarabha zvinogona kuparadzwa. Manozzle madiki esimbi akagadzirwa nesimbi aratidza kukosha kwawo pano, ayo anotora nzvimbo yekutonhodza panguva ino uye nokudaro anodzivirira mari yefekitori yemhepo inobvisa sulphurisation.
Kuomarara kwesilicon carbide (SiSiC): Moh's hardness ndeye 9.2, ine simba guru rekukurwa nekuora, inodzivirira kukwesha uye inodzivirira oxidation. Yakasimba ka4 kusvika ka5 kupfuura nitride bonded silicon carbide. Hupenyu hwekushanda hwakareba ka7 kusvika ka10 kupfuura alumina material. MOR yeRBSiC yakapetwa ka5 kusvika ka7 kupfuura SNBSC, inogona kushandiswa kune mamwe maumbirwo akaomarara.
Shandong Zhongpeng Special Ceramics Co., Ltd ndeimwe yemhando huru dzesilicon carbide ceramic itsva muChina. SiC technical ceramic: Kuomarara kwaMoh kwa9 (Kuomarara kwaNew Moh kwa13), nekusimba kwakanaka pakukukurwa nekuora, kusimba kwakanaka - kusimba uye kudzivirira oxidation. Hupenyu hwebasa rechigadzirwa cheSiC hwakareba ka4 kusvika ka5 kupfuura 92% alumina material. MOR yeRBSiC yakapetwa ka5 kusvika ka7 kupfuura SNBSC, inogona kushandiswa kune mamwe maumbirwo akaomarara. Maitiro ekukosha kwemashoko anokurumidza, kuendesa kwacho kwakaitwa sezvakavimbiswa uye mhando yacho haina kukosha. Tinogara tichiramba tichipikisa zvinangwa zvedu uye tinopa moyo yedu kunharaunda.
