Ukucoca Amanzi Aneasidi Avela Kwi-Ammonia Wash Towers – Isihluzi Sebhasikithi

I. Imvelaphi yemeko yokusebenza: Imingeni enzima yolwelo oluneasidi

Isihluzo see-intshi ezi-8 esisetyenziswa ngabathengi base-Israel sicubungula amanzi ane-asidi avela kwi-ammonia wash tower, enexabiso le-pH elimalunga ne-3. Asiqulathi kuphela i-25% ye-ammonium sulfate kodwa sikwanazo neentwana ezincinci eziveliswa ngexesha lokuhlamba umoya. Le ndawo iphakathi ene-asidi eninzi nerhabaxa ibeka iimfuno eziphezulu kakhulu ekuchaseni ukugqwala kunye nokuzinza kwesakhiwo sezinto zokucoca. Ubukho be-ammonium sulfate bukhawulezisa ukugqwala kunye nokuguga kwezinto zesinyithi eziqhelekileyo, ngelixa iintwana ezixhonyiweyo zinokubangela ukuvaleka kwangaphakathi kwesihluzo, okuchaphazela ukusebenza okuzinzileyo kwexesha elide kwezixhobo. Ke ngoko, kubalulekile ukukhetha isixhobo sokucoca esikwaziyo ukuzivumelanisa nezimo.

II. Ingcebiso eyenziwe ngokwezifiso:Isihluzi seBhasikithi esigqunywe nge-316L + PTFE

Ukuphendula kwiimeko zokusebenza ezinzima ezingentla, emva kohlalutyo lobuchwephesha kunye nokukhetha, sicebisa umthengi wase-Israel ukuba abhaleIzinto zentsimbi engagqwaliyo ezingama-316L ezidityaniswe nesihluzo sebhasikithi esigqumayo se-PTFE (polytetrafluoroethylene)Iingenelo eziphambili zesi sisombululo zezi zilandelayo:

Okokuqala, intsimbi engagqwaliyo engama-316L, njengesixhobo esixhathisa ukugqwala esisetyenziswa rhoqo kwicandelo lemizi-mveliso, inomthamo wekhabhoni ophantsi xa ithelekiswa nentsimbi engagqwaliyo eqhelekileyo engama-316, enokumelana nokugqwala okuphezulu phakathi kweegranular, enokumelana ngempumelelo nokugqwala kokuqala kwindawo ene-asidi, inika isiqinisekiso solwakhiwo oluqinileyo lwesiseko sesihluzi. Okwesibini,Ukwaleka kwe-PTFEineempawu ezizodwa "zokunganamatheli, ukumelana nokugqwala, kunye nokumelana nobushushu obuphezulu", eyaziwa ngokuba yi "plastic king", enokuhlala izinzile kuluhlu lwe-pH oluyi-1-14 kwii-asidi ezinamandla kunye neziseko ezinamandla, ihlukanisa ngokuqinileyo unxibelelwano oluthe ngqo phakathi kwesisombululo se-ammonium sulfate kunye ne-substrate yentsimbi engagqwali, ngokusisiseko isombulula ingxaki yokukhukuliseka kwemidiya egqwalisiweyo kwizixhobo, kwaye yandisa ubomi benkonzo yesihluzi.

Kwangaxeshanye, uyilo lwesakhiwo sesihluzo sebhasikithi lulungelelaniswe neemfuno zokucubungula amasuntswana aqulethe ulwelo. Ibhasikithi yesihluzo eyakhelwe ngaphakathi isebenzisa izixhobo zokucoca ezichanekileyo, ezinokubamba ngokufanelekileyo inani elincinci lamasuntswana kulwelo, zithintele ukuvaleka kwemibhobho; kwaye isakhiwo sebhasikithi silungele ukuqhaqhwa nokucocwa, nto leyo enokunciphisa iindleko zokugcinwa kwezixhobo kwaye iqinisekise ukusebenza okuqhubekayo nokuzinzileyo kwenkqubo yokucoca, ihambelana ngokugqibeleleyo neemeko zokusebenza zomthengi.

III. Ixabiso lesisombululo: Ukhetho olufanelekileyo loKhuseleko nokusebenza kakuhle

Kwiimeko ezinzima zokusebenza kolwelo lwe-asidi erhabaxa, izihluzi zentsimbi engagqwaliyo zinzima ukumelana nokukhukuliseka kwendawo yokusebenzela ixesha elide, zinokuba nokuvuza nokonakala, zinganyusi nje iindleko zokutshintshwa kwezixhobo kodwa zikwachaphazela inkqubela phambili yemveliso ngenxa yokuvalwa kwezixhobo ukuze zilungiswe.Isihluzi sebhasikithi esine-316L + PTFE esigqunywe nge-coated, ngokukhusela izinto kunye nokwaleka kabini, ayisombululi nje kuphela ingxaki yokugqwala kwesisombululo se-ammonium sulfate kodwa ikwaphatha ngokufanelekileyo ukungcola kwamasuntswana, ifezekisa iziqinisekiso ezimbini zokhuseleko kunye nokusebenza.

Esi sisombululo siqinisekiswe ngeemeko ezininzi ezifanayo zokusebenza kwezoshishino kwaye sinamava okusebenza avuthiweyo, sibonelela ngenkxaso ethembekileyo yokucoca inkqubo yokuvelisa umthengi wase-Israel, sinceda umthengi ukuba aphephe iingozi zokugqwala kwezixhobo, sinciphise iindleko zokusebenza kunye nokugcinwa, kwaye lolona khetho lufanelekileyo oludibanisa ukhuseleko, ukusebenza kakuhle, kunye noqoqosho.
