Yintoni iNqaba yokuPholisa eVulekileyo?

 

 

Ngokumalunga nokwakheka kwesakhiwo, iinqaba zokupholisa ezivulekileyo ikakhulu zibandakanya izinto eziphambili ezinje ngomzimba wenqaba, izinto zokuzalisa, ifeni, inkqubo yokuhambisa amanzi, i-sump kunye ne-air inlet louvers. Ngethuba lokusebenza, amanzi ajikelezayo ukuba apholise ahanjiswe kwinkqubo yokuhanjiswa kwamanzi phezulu kwinqaba ngepompo yamanzi, kwaye emva koko ifafazwe ngokulinganayo phezu kwendawo yokuzalisa izinto ngokusebenzisa imibhobho okanye imibhobho yokuhambisa amanzi ukwenza ifilimu yamanzi amancinci. Okwangoku, i-fan efakwe ezantsi okanye phezulu kwinqaba iqhuba umoya ukuze ingene kwinqaba ngokusebenzisa i-air inlet louvers, yenza i-countercurrent or crossflow contact kunye nefilimu yamanzi kwindawo yokuzalisa. Kule nkqubo, ngakwesinye icala, ukuhanjiswa kobushushu be-convective kwenzeka phakathi komoya kunye namanzi, ukuhambisa inxalenye yobushushu obunengqiqo emanzini ukuya emoyeni; kwelinye icala, inxalenye yamanzi ajikelezayo ifunxa ubushushu kwaye ibe ngumphunga, ithatha umthamo omkhulu wobushushu obufihlakeleyo. Ngaphantsi kweempembelelo ezimbini zokutshintshiselana kobushushu, amanzi apholileyo awela kwi-sump ephantsi kwenqaba, kwaye aphinde aqhutywe kwisixhobo esipholileyo ukuze siphinde sisetyenziswe, ngelixa umoya oshushu kunye nomswakama ukhutshwa emoyeni ngokusebenzisa i-cylinder yomoya phezulu kwinqaba.

 

 

 

Ezona zinto ziluncedo kwiinqaba zokupholisa ezivulekileyo zilele ekusebenzeni kwazo okuphezulu kokupholisa{0}ukutshintshiselana ngokuthe ngqo kobushushu kunokususa ngokukhawuleza ubushushu kumanzi ajikelezayo ukuhlangabezana neemfuno zokupholisa{1}zezixhobo zombane eziphezulu. Okwangoku, banesakhiwo esilula kunye nokuthengwa okuphantsi, ukufakwa kunye neendleko zokugcina; Isithuba sesiqhelo-sokusebenza sifuna kuphela ukucocwa rhoqo kwezinto zokuzalisa, ukuhlolwa kunye nokulungiswa kweefeni, kunye nokuzaliswa kwamanzi ajikelezayo. Nangona kunjalo, izixhobo ezinjalo nazo zinemida ecacileyo: ngenxa yoqhagamshelwano oluthe ngqo phakathi kwamanzi ajikelezayo kunye nomoya, uthuli, ukungcola, i-microorganisms kunye nezinye izinto ezisemoyeni zinoxanduva lokungena kumzimba wamanzi, okukhokelela ekudakaleni komgangatho wamanzi ojikelezayo, nto leyo ebangela ukunyuswa kunye nokubola kwemibhobho kunye nabatshintshisi bobushushu.

 

 

Ngoko ke, kuyimfuneko ukuxhobisa ngenkqubo yokucoca amanzi kwaye ungeze rhoqo ii-agent zokunyanga amanzi ezifana ne-scale inhibitors kunye ne-bactericides. Ukongeza, iinqaba zokupholisa ezivulekileyo zinelahleko yokumka kwamanzi, nto leyo enqanda ukusetyenziswa kwamanzi{1}}kwiindawo ezinqabileyo okanye iimeko ezinovakalelo kusetyenziso lwamanzi.

 

 

 

Kwizicelo ezisebenzayo, iinqaba zokupholisa ezivulekileyo zihlala zihlelwa zibe ziindidi ezimbini ngokwendlela yokungenisa umoya: uhlobo lwe-crossflow kunye nohlobo lwe-counterflow. Kwiinqaba zokupholisa ezinqamlezileyo ezivulekileyo, icala lokuhamba komoya lithe gqolo ukuya kwelo lokuhamba kwamanzi, linobude bomzimba obuphantsi kunye nokugcinwa okufanelekileyo. Kwiindawo zokupholisa ezivulekileyo zokuqukuqela, umoya uqukuqela usiya kwelinye icala lokuhamba kwamanzi, oko kwenza ukuba utshintshiselwano lobushushu olwaneleyo kunye nokusebenza kakuhle kokupholisa, ngaloo ndlela ulungele iimeko zemizi-mveliso ezineemfuno ezingqongqo zokupholisa.
