Ukusetyenziswa kwe-filter press kwishishini le-hot-dip galvanizing eVietnam

Ulwazi olusisiseko:Eli shishini licubungula iitoni ezingama-20000 ze-hot-dip galvanizing ngonyaka, kwaye amanzi amdaka emveliso ikakhulu ngamanzi amdaka. Emva kokucocwa, ubungakanani bamanzi amdaka angena kwisikhululo sokucocwa kwamanzi amdaka yi-1115 cubic metres ngonyaka. Ukubalwa ngokusekelwe kwiintsuku ezingama-300 zokusebenza, ubungakanani bamanzi amdaka aveliswayo bumalunga ne-3.7 cubic metres ngosuku.

Inkqubo yonyango:Emva kokuqokelela amanzi amdaka, isisombululo se-alkaline songezwa kwitanki elawula ukunganyamezeli ukuze kulungiswe ixabiso le-pH libe yi-6.5-8. Umxube uyalingana kwaye ulingane ngokushukumisa nge-pneumatic, kwaye ezinye ii-ion ze-ferrous ziyaxutywa zibe yi-ion ze-iron; Emva kokunyibilika, amanzi amdaka angena kwitanki ye-oxidation ukuze aphefumle kwaye axutywe, aguqule ii-ion ze-ferrous ezingasuswanga zibe yi-ion ze-iron kwaye asuse imeko yokuba tyheli kwi-druent; Emva kokunyibilika, amanzi amdaka angena ngokuzenzekelayo kwitanki yamanzi asetyenziswa kwakhona, kwaye ixabiso le-pH lilungiswa ukuya kwi-6-9 ngokongeza i-asidi. Malunga ne-30% yamanzi acocekileyo asetyenziswa kwakhona kwicandelo lokuhlamba, kwaye amanzi acocekileyo aseleyo ahlangabezana nomgangatho kwaye aqhagamshelwe kwinethiwekhi yemibhobho yamanzi amdaka yasekhaya kwindawo yefektri. Udaka oluvela kwitanki ye-sedimentation luphathwa njengenkunkuma eqinileyo enobungozi emva kokususwa kwamanzi, kwaye i-filtrate ibuyiselwa kwinkqubo yonyango.

Izixhobo zokucoca isihluzi: Ukususa amanzi ngoomatshini kwidaka kusebenzisa izixhobo ezifana ne-XMYZ30/630-UBucinezelo lokucoca(umthamo uwonke wegumbi lokucoca yi-450L).

Amanyathelo okwenziwa ngokuzenzekelayo:Izixhobo zokuzilawula ze-pH zifakelwe kuzo zonke iindawo ezibandakanya ulawulo lwexabiso le-pH, okwenza kube lula ukuyisebenzisa kwaye kongiwe umthamo wamayeza. Emva kokuba kugqityiwe ukuguqulwa kwenkqubo, ukukhutshwa ngqo kwamanzi amdaka kwancitshiswa, kwaye ukukhutshwa kwezinto ezingcolisayo ezifana ne-COD kunye ne-SS kwancitshiswa. Umgangatho wokungcola ufikelele kwinqanaba lesithathu loMgangatho oQokelelweyo woKukhutshwa kwamanzi amdaka (GB8978-1996), kwaye i-zinc iyonke ifikelele kwinqanaba lokuqala.
