Yintoni ukuhanjiswa kwe-pneumatic?
I-pneumatic conveying kuthuthwa kwezinto eziqinileyo ezininzi ngombhobho ngokusebenzisa ukuhamba komoya okanye enye igesi.... Ukuthuthwa kwe-pneumatic kunokwakhiwa njengoxinzelelo oluhle okanye inkqubo yokucoca.
Ukuhanjiswa komgubo wepneumatic kusebenzisa amandla okuhamba komoya.Ukuhanjiswa kwe-pneumatic kukwabizwa ngokuba yinkqubo yokuhambisa umoya okanye inkqubo yokuhambisa umoya.Isicelo esithile sobuchwephesha be-fluidization ukuthutha izinto zegranular ecaleni kwendlela yokuhamba komoya kumbhobho ovaliweyo.Uyilo lwesixhobo sokuhambisa umoya silula kwaye kulula ukusebenza.Ingasetyenziselwa ukuthutha okuthe tye, okuthe nkqo okanye okuthe tye.Ngexesha lenkqubo yothutho, imisebenzi yomzimba efana nokufudumeza, ukupholisa, ukuhlelwa kokuhamba kweyomileyo, okanye eminye imisebenzi yekhemikhali nayo inokwenziwa ngaxeshanye.
Ngokwengxinano yamasuntswana othutho lwemibhobho, uthutho lwe-pneumatic lwahlulwe lube:
1. Ukuthuthwa kwesigaba se-Dilute: umxholo oqinileyo ungaphantsi kwe-100kg / m3 okanye i-solid-to-gas ratio (i-mass flow rate ratio phakathi komthamo wothutho oluqinileyo kunye nokusetyenziswa kwegesi ehambelanayo) ngu-0.1-25.Isantya segesi esisebenzayo siphezulu ngokwentelekiso (malunga ne-1830ms, ngokoxinzelelo lwerhasi kumbhobho, yahlulahlulwe ngohlobo lokufunxa kunye nohlobo lonikezelo loxinzelelo. yothulwa phantsi koxinzelelo olubi, kwaye inokuthuthwa ngokurhabaxa Umgama mfutshane, uxinzelelo kumbhobho wokugqibela luphezulu kunoxinzelelo lwe-atmospheric, kwaye ukukhutshwa kukulungele, kwaye kunokuthuthwa umgama omde, kodwa umgubo. amasuntswana kufuneka athunyelwe kumbhobho woxinzelelo nge-feeder.
2. Ukuthuthwa kwesigaba esixineneyo: inkqubo yokuthutha apho umxholo oqinileyo uphezulu kune-100kg / m3 okanye umlinganiselo we-gas oqinileyo ungaphezulu kwe-25. Isantya somoya esisebenzayo siphantsi, kwaye uxinzelelo lomoya oluphezulu lusetyenziselwa ukwenza inkqubo yokuhambisa umoya. .Ngamathuba athile itanki ezaliswe luhlobo lothutho lwesigaba esishinyeneyo.Beka amaqhekeza kwitanki yoxinzelelo kwiibhetshi, kwaye emva koko ukhuphe umoya ukuze uzikhulule.Xa uxinzelelo kwitanki lufikelela kuxinzelelo oluthile, vula i-valve yokukhupha kwaye uvuthele amaqhekeza kumbhobho wokuhambisa ukuthutha.Ukuhanjiswa kwe-Pulse kukudlula umoya ocinezelekileyo kwitanki esezantsi ukukhulula izinto;enye i-pulse compressed atmosphere flow with frequency of 2040min-1 ivuthelwa kwi-inlet yombhobho wesondlo, isenza iikholamu ezincinci ezicwangcisiweyo kunye namacandelo amancinci kumbhobho Ikholamu yomoya isebenzisa uxinzelelo lwe-atmospheric ukutyhala phambili.Ukuthuthwa kwesigaba esixineneyo kunamandla amakhulu okuthutha, kunokucinezelwa umgama omde, umonakalo wezinto eziphathekayo kunye nokunxiba koqwalaselo kuncinci, kwaye ukusetyenziswa kwamandla kuncinci.Xa uqhuba uthutho lwesigaba se-dilute kwinkqubo yothutho yepayipi ethe tye, isantya segesi kufuneka sibe phezulu ukwenzela ukuba amasuntswana akhutshwe kwaye anqunyanyiswe kwi-airflow.Xa ukhetha ukuhanjiswa kwesigaba sokuxubha okanye ukuhanjiswa kwesigaba esishinyeneyo, kuyilwe ngokwemveliso yokuhambisa kunye nokusebenza kwemathiriyeli yomgubo.
