Itekhnoloji yeplanti yokubuyisela iDMF ukusuka kwiGasi yeNkunkuma yeNkunkuma yeNkunku eManzi yePolyurethane Synthetic yesikhumba
Ubungqina obucacileyo: Itekhnoloji entsha yokubuyisela i-DMF iphuhliswe ukuphinda isetyenziswe i-N,N-dimethyl formamide(DMF) kwinkunkuma yerhasi evela kushishino lwesikhumba olumanzi lwe-polyurethane.Njengoko i-concentration ye-DMF kwi-gas yenkunkuma yayiphantsi njenge-325.6-688.3 mg · m-3, kwakuyimfuneko ukuba kuqinisekiswe ukuba izigaba ezibini ziqhagamshelana ngokufanelekileyo kwaye zomeleze ukuhanjiswa kobuninzi ngokunyusa indawo yoqhagamshelwano kunye nokuphucula i-turbulence.Ke ngoko, ukufunxwa kwenqanaba eliphindwe kabini kunye nenqanaba elimbini lokususa inkungu kwangeniswa kubuchwephesha.Icandelo eliphezulu lekholomu yokufunxa lizaliswe nge-structured wire-ripple steel stainless steel packing BX500, ngelixa icandelo elisezantsi kunye ne-sting-ripple packing CB250Y.Ubude obupheleleyo bezinto zokupakisha kwakuyi-6 m.Ukongeza, bekukho zombini inqanaba lokususa inkungu umaleko kunye nomgangatho ophezulu wokuhambisa ulwelo kumphezulu wekholamu.Zonke iiparameters zokusebenza, kubandakanywa ubushushu, uxinzelelo, izinga lokuhamba kunye nokuma kwamanzi, kunokulawulwa kwiikhomputha ngaphandle kokusebenza ngesandla, ukuqinisekisa ukuba igesi yokuphuma iphumelele umgangatho wokukhutshwa kwelizwe ukuba i-DMF igxininise kufuneka ibe ngaphantsi kwe-40 mg · m-3. izixhobo ezipheleleyo zinokubuyisela i-237.6 t ye-DMF ngonyaka ngamnye, kunye nenzuzo ukuya kwi-CNY 521 × 103.
