Guangzhou Rongjie NMP nidaamka dib u warshadaynta

Mabda'a

Gaaska qashinka ah ee NMP ee ka soo baxa dahaarka wuxuu gaaraa qalabka sanduuqa shaandhada isagoo maraya tuubada qiiqa si loo nadiifiyo loona sifeeyo, ka dibna waxaa loo diraa qalabka soo kabashada kulaylka qashinka ka dibna waxaa loo diraa qalabka martida loo yahay ee isku-darka si loogu qaboojiyo loona qaboojiyo. Inta badan NMP-ga ku jira gaaska qashinka ah waa la soo ururin karaa oo waxaa la gelin karaa nidaamka dareeraha qashinka, fiirsashada NMP ee gaaska qashinka ah ee isku-darka ahna waxaa la dhimayaa ilaa 300ppm.

90 ~ 95% gaaska qashinka ee heerkulka hooseeya ka dib marka uu qaboojiyo waxaa loo diraa qalabka soo kabashada kulaylka qashinka, halkaas oo uu kulayl ku beddelo gaaska qashinka ee heerkulka sare leh ee uu sii daayo mashiinka dahaadhka, ka dibna gaaska qashinka ee heerkulka hooseeya ayaa la kululeeyaa si uu u buuxiyo shuruudaha hawada soo noqoshada waxaana dib loogu celiyaa mashiinka dahaadhka, sidaas darteedna si buuxda ayaa loo ogaaday soo kabashada tamarta kulaylka iyo badbaadinta isticmaalka tamarta kuleylinta ee uu u baahan yahay mashiinka dahaadhka.

Orodyahanka shaandhada VOCS zeolite molecular waxaa loo qaybiyaa aagga daaweynta nuugista, aagga qaboojinta iyo aagga baabi'inta, waxaana kaxeeya matoorka, taasoo ka dhigaysa orodyahanka inuu si tartiib tartiib ah u wareego, si joogto ah u nuugo oo dib u soo nooleeyo, oo dib u warshadeeyo gaaska dabada. 5 ~ 10% gaaska qashinka ee la isku daray ayaa lagu qasaa hawada heerkulka sare leh ee aagga baabi'inta wuxuuna galaa qaybta qaboojinta dusha sare ee orodka, halkaas oo lagu qaboojiyo oo la isku ururiyo, inta badan NMP-na waa la soo ururin karaa oo la geli karaa nidaamka dareeraha qashinka. Kadib waxaa loo dirayaa aagga daaweynta nuugista, hawada buuxisa heerka ka dib nuugista waxaa dibadda u daadin kara taageere.

Intaa waxaa dheer, xaddi yar oo hawo tayo leh ayaa dib loo warshadeeyaa si loogu beddelo kulaylka aagga qaboojinta, si hawada loo kululeeyo oo orodyahankana loo qaboojiyo. Hawada kulul waxaa lagu kululeeyaa qalab kuleylin (kuleyliyaha uumiga ama kuleyliyaha korontada ama kuleyliyaha saliidda wareejinta kulaylka), ka dibna NMP-ga ku jira zeolite-ka orodka ayaa lagu nuugaa aagga nabaad-guurka, hawada heerkulka sare leh ee ka kooban NMP-ga aagga nabaad-guurkana waxaa loo diraa qaybta qaboojinta dusha sare ee orodka. Geedi socodka orodka oo dhan wuxuu si buuxda u isticmaalaa dib-u-warshadaynta tamarta kulaylka wuxuuna badbaadiyaa isticmaalka tamarta kuleylinta ee uu u baahan yahay mashiinka dahaadhka.
