Ubuchwepheshe bemboni yokutakula i-DMF evela ku-Wet Type Polyurethane Synthetic Leather Waste Gas

Umbono: Ubuchwepheshe obusha bokutholwa kwe-DMF buthuthukisiwe ukuze kusetshenziswe kabusha i-N,N-dimethyl formamide(DMF) kugesi ewudoti ovela embonini yesikhumba yokwenziwa ye-polyurethane emanzi. Njengoba kunikezwe ukuthi ukugxilwa kwe-DMF kugesi engcolile kwakuphansi njenge-325.6-688.3 mg·m-3, kwakudingeka ukuqinisekisa ukuthi izigaba ezimbili zithintana ngokwanele futhi kuqiniswe ukudluliswa kwenqwaba ngokwandisa indawo yokuxhumana nokuthuthukisa isiyaluyalu. Ngakho-ke, ukumuncwa kwe-countercurrent okunezigaba ezimbili kanye nohlelo lokususa inkungu olunezigaba ezimbili lwafakwa kubuchwepheshe. Ingxenye engaphezulu yekholomu yokumuncwa igcwaliswe ngensimbi engagqwali ye-wire-ripple ehlelekile epakishwayo i-BX500, kuyilapho ingxenye engezansi ene-sting-ripple packing CB250Y.Ingqikithi yobude bokupakisha bebuyi-6 m. Ngaphezu kwalokho, bekukhona kokubili ungqimba olunezigaba ezimbili zokususa inkungu kanye nokusabalalisa uketshezi olusebenza kahle kakhulu phezulu kwekholomu. Yonke imingcele yokusebenza, okuhlanganisa izinga lokushisa, ingcindezi, izinga lokugeleza kanye nesimo se-liquid, ingalawulwa amakhompiyutha ngaphandle kokusebenza ngesandla, ukuqinisekisa ukuthi igesi ephumayo ifinyelela izinga lokuphuma likazwelonke lokuthi ukugxilwa kwe-DMF kufanele kube ngaphansi kuka-40 mg·m-3. isisetshenziswa sonke singabuyisa u-237.6 t we-DMF unyaka ngamunye, ngenzuzo efika ku-CNY 521×103.
