A: Ulawulo oluchanekileyo loxinzelelo lomphunga luhlala lubalulekile kuyilo lwenkqubo yomphunga kuba uxinzelelo lomphunga luchaphazela umgangatho womphunga, ubushushu bomphunga, kunye nokukwazi ukufudumeza ubushushu bomphunga. Uxinzelelo lomphunga lukwachaphazela ukukhutshwa kwe-condensate kunye nokuveliswa komphunga okwesibini.
Kubathengisi bezixhobo zebhoyili, ukwenzela ukunciphisa umthamo weebhoyili kunye nokunciphisa iindleko zezixhobo zebhoyili, iibhoyili ze-steam zidla ngokuyilwa ukuba zisebenze phantsi koxinzelelo oluphezulu.
Xa ibhoyila isebenza, uxinzelelo lwangempela lokusebenza luhlala luphantsi kunoxinzelelo olusebenzayo loyilo. Nangona ukusebenza kuphantsi koxinzelelo, ukusebenza kwebhoyili kuya kwandiswa ngokufanelekileyo. Nangona kunjalo, xa usebenza ngoxinzelelo oluphantsi, umphumo uya kuncitshiswa, kwaye uya kubangela ukuba umphunga "uthwale amanzi". I-vapor carryover yinkalo ebalulekileyo yokusebenza kakuhle kokucoca umphunga, kwaye le lahleko idla ngokuba nzima ukuyibhaqa kunye nokulinganisa.
Ngoko ke, iibhoyili ngokubanzi zivelisa umphunga kuxinzelelo oluphezulu, oko kukuthi, zisebenza ngoxinzelelo olusondeleyo kuxinzelelo loyilo lwebhoyili. Ukuxinana komphunga woxinzelelo oluphezulu kuphezulu, kwaye amandla okugcina igesi kwindawo yawo yokugcina umphunga nawo uya kwanda.
Ubuninzi be-steam-high-pressure steam buphezulu, kwaye ubuninzi be-steam-high-pressure steam odlula umbhobho we-diameter efanayo mkhulu kune-low-pressure steam. Ke ngoko, uninzi lweenkqubo zokuhambisa umphunga zisebenzisa umphunga woxinzelelo oluphezulu ukunciphisa ubungakanani bombhobho wokuhambisa.
Ukunciphisa uxinzelelo lwe-condensate kwindawo yokusetyenziswa ukugcina amandla. Ukunciphisa uxinzelelo kwehlisa iqondo lobushushu kwimibhobho esezantsi, kunciphisa ilahleko emileyo, kwaye kunciphisa ilahleko yomphunga odanyazayo njengoko uphuma kumgibe ukuya kwitanki yokuqokelela i-condensate.
Kuyafaneleka ukuba uqaphele ukuba ilahleko yamandla ngenxa yokungcola iyancitshiswa ukuba i-condensate ikhutshwe ngokuqhubekayo kwaye ukuba i-condensate ikhutshwe ngoxinzelelo oluphantsi.
Ekubeni uxinzelelo lomphunga kunye nobushushu zihambelana, kwezinye iinkqubo zokufudumeza, ubushushu bunokulawulwa ngokulawula uxinzelelo.
Esi sicelo sinokubonwa kwii-sterilizers kunye ne-autoclaves, kwaye umgaqo ofanayo usetyenziselwa ukulawula ubushushu bomhlaba kwi-dryer zokudibanisa zephepha kunye nezicelo zebhodi edibeneyo. Kwiintlobo ezahlukeneyo zokudibanisa i-rotary dryer, uxinzelelo lokusebenza luhambelana ngokusondeleyo nesantya sokujikeleza kunye nobushushu obuphuma kwesomisi.
Ulawulo loxinzelelo lukwasisiseko solawulo lobushushu bokutshintsha ubushushu.
Ngaphantsi komthwalo ofanayo wokushisa, umthamo we-heat exchanger osebenza kunye ne-low-pressure steam mkhulu kunomsebenzi wokushisa osebenza ngoxinzelelo oluphezulu. Uxinzelelo oluphantsi lokutshintsha ubushushu alubizi kakhulu kunoxinzelelo oluphezulu lokutshintsha ubushushu ngenxa yeemfuno zabo zoyilo oluphantsi.
Isakhiwo seworkshop sinquma ukuba isixhobo ngasinye sinoxinzelelo oluphezulu oluvumelekileyo lokusebenza (MAWP). Ukuba olu xinzelelo lungaphantsi koxinzelelo oluphezulu olunokwenzeka lwe-steam enikeziweyo, i-steam kufuneka igxininiswe ukuze kuqinisekiswe ukuba uxinzelelo kwinkqubo ephantsi yomlambo ayigqithisi ubuninzi bokusebenza ngokukhuselekileyo.
Izixhobo ezininzi zifuna ukusetyenziswa kwe-steam kwiingcinezelo ezahlukeneyo. Isixokelelwano esithile sidanyaza amanzi anyuswe ngoxinzelelo oluphezulu kuxinzelelo oluphantsi lomphunga ukuze unikeze ezinye iinkqubo zokufudumeza izicelo zokufezekisa iinjongo zokonga umbane.
Xa isixa se-flash steam esiveliswayo asanelanga, kuyimfuneko ukugcina unikezelo oluzinzileyo noluqhubekayo lwe-steam-low-pressure. Ngeli xesha, ivalve yokunciphisa uxinzelelo iyafuneka ukuhlangabezana nemfuno.
Ulawulo loxinzelelo lomphunga lubonakaliswa kwiikhonkco ze-lever zokuvelisa umphunga, ukuthutha, ukuhanjiswa, ukutshintshiselana kobushushu, amanzi adibeneyo kunye ne-flash steam. Indlela yokuhambelana noxinzelelo, ukushisa kunye nokuhamba kwenkqubo ye-steam ngundoqo kuyilo lwenkqubo ye-steam.
