Resource Treatment of Black Liquor from Papermaking by Spray Drying
Kuba uninzi lwemathiriyeli ekrwada yokucofa e-China ingeyiyo imathiriyeli yefiber ekrwada (ibalelwa ngaphezulu kwe-50%), iindlela zokubuyisela i-alkali kunye ne-asidi zisetyenziswa kunyango lotywala olumnyama kwiindawo ezininzi zokugaya amaphepha. Nangona kunjalo, ngenxa yokungasebenzi kakuhle kokuhluzwa kwamanzi kwi-pulp yengca, iiseli ezininzi ezixubileyo kutywala obumnyama, i-viscosity ephezulu kunye nomxholo ophezulu we-silicon wotywala obumnyama, impembelelo yokwenene yokusebenza yendlela yokubuyisela i-alkali imbi, izinga lokubuyisela i-alkali limalunga ne-60% kuphela, ukusebenza kakuhle kwe-thermal, iindleko eziphezulu zokusebenza kunye nolawulo olunzima. Ke ngoko, kunzima ukusombulula ngokupheleleyo ingxaki yongcoliseko lotywala olumnyama kwisityalo se-straw pulp. Ngokwesiseko sophando kunye nophuhliso lokomisa isitshizi kunye noxinzelelo lomoya wokuba ngumphunga iminyaka emininzi, kwaye kudityaniswa nokuyila kunye namava okusebenza okwazisa inkqubo enye yokunyuka komphunga kunye nokuxinana kotywala obumnyama kumazwe angaphandle, inkampani yethu iphakamise kwaye yaphumeza inkqubo yokukhupha ungcoliseko lwe-zero kunyango lotywala olumnyama.
Amanzi ajikisiweyo kunye notywala obumnyama obujiyileyo buphuma kwi-evaporator, i-condensate ingasetyenziswa njengamanzi okuhlamba, ngelixa utywala obumnyama obugxininisiweyo bungena kwindawo yokutshiza. Ngethuba lokumisa inkqubo yokutshiza, ubuninzi bothuli olukhutshwe kwinkqubo yokumisa lungaphantsi kwe-100 ~ 150 mg / m3, enokuthi ihlangabezane nemigangatho yokukhutshwa kwelizwe. Akukho nkunkuma yenkunkuma ekhutshwayo, kwaye iimveliso ze-lignin zifunyenwe ngexesha elifanayo. Iyonke inkqubo yonyango lotywala olumnyama ayinzima ukuyifumana, kwaye akukho nkunkuma yerhasi kunye nokulahlwa kwenkunkuma yolwelo kuyo yonke le nkqubo, ukuze kuphunyezwe injongo yokungakhutshelwa kongcoliseko kunyango lotywala olumnyama. Iphepha elenziwa utywala obumnyama lwenziwa kwiimveliso ze-lignin ukuze zisetyenziswe ngokupheleleyo. Isetyenziswa ngokubanzi kwisinciphisi samanzi ekhonkrithi, i-disperant yamanzi yamalahle, i-asphalt emulsifier, iikeramics, izongezo zokuxhaphazwa kwe-oyile, njl.njl., ukuze kupheliswe umonakalo wendalo esingqongileyo, ukudala indlela yophuhliso enobubele, yendalo kunye nemvisiswano, kwaye iqonde ngokwenene umanyano lwezibonelelo zoqoqosho, iinzuzo zokusingqongileyo kunye neenzuzo zentlalo.
Akukho kukhutshwa kwenkqubo yokukhutshwa kotywala obumnyama
1. Izinto:ukwenza iphepha lotywala olumnyama kunye notywala obubomvu
2. Ubushushu bokungenisa umoya:280 ℃ ~ 430 ℃
3. Ubushushu bendawo yomoya:110 ℃
4. Imveliso yomgubo owomileyo:1000 kg / H ~ 4000kg / h
5. Umxholo oqinileyo:40% ~ 50%
6. Umthombo wobushushu:isitovu esitshisayo esiqhunyiswa ngamalahle esinegumbi lokuzinzisa, umphunga oshushu kakhulu, njl. njl. (unokutshintshwa ngokwemiqathango yabathengi)
7. Imowudi yeAtomization:isantya esiphezulu se-atomizer ye-centrifugal yamkelwe
8. Indlela yokufudumeza:isitovu esitshisayo esiqhunyiswa ngamalahle (esinegumbi lokuhlala elinamanqanaba amane ukuthintela ngokufanelekileyo iMars ukuba ingangeni)
9. Ukubuyisela izinto eziphathekayo:ukususwa kothuli oluphambili lwenkanyamba kunye nokususwa kothuli lwamanzi amanzi okwesibini kwamkelwa, kunye nesantya sokubuyisela i-99.8%, ehambelana nemigangatho yesizwe yoMbane.
10. Ukufumana:ukwamkela okuphakathi kwamkelwe. I-bottom of the tower kunye nomgubo okhutshwe kumqokeleli wothuli lwe-cyclone zithunyelwa ngokufanayo kwi-air conditioning system Ukupakishwa kuya kuqhutyelwa kwindawo yokugcina i-workshop yokupakisha echongiweyo.
11. Ulawulo lombane:Ulawulo lwenkqubo ye-PLC lwamkelwa. (ulawulo oluzenzekelayo lobushushu bokungena komoya, ubushushu bokuphuma komoya, ubushushu be-oyile kunye ne-alam yoxinzelelo lweoyile ye-atomizer kunye nokuboniswa koxinzelelo olubi kwinqaba)
