Indlela yokuPhuhlisa iBhola yomphunga
Zimbini iindlela eziphambili zokuvuthela kwizibiyila zomphunga, ezizezi, ukubhutha komzantsi kunye nokuqhushumba okuqhubekayo. Indlela yokukhutshwa kwamanzi amdaka, injongo yokukhutshwa kwamanzi amdaka kunye nokuqhelaniswa nokufakwa kwezi zibini zihluke, kwaye ngokuqhelekileyo azikwazi ukuthatha indawo enye kwenye.
Ukuvuthela okusezantsi, okwabizwa ngokuba yi-timed blowdown, kukuvula ivalve yobubanzi obukhulu ezantsi kwibhoyila imizuzwana embalwa ukuvuthela, ukuze umthamo omkhulu wamanzi embiza kunye nentlenga ikhutshelwe ngaphandle phantsi kwesenzo sebhoyila. uxinzelelo. . Le ndlela yindlela efanelekileyo ye-slagging, enokuthi ihlulwe ibe yi-manual control kunye nokulawula ngokuzenzekelayo.
Ukuvuthela ngokuqhubekayo kukwabizwa ngokuba yi-surface blowdown. Ngokuqhelekileyo, i-valve ibekwe kwicala lebhoyili, kwaye ubungakanani bokungcola bulawulwa ngokulawula ukuvulwa kwe-valve, ngaloo ndlela ilawula ukuxinwa kwe-TDS kwi-solids e-soluble yamanzi kwibhoyili.
Zininzi iindlela zokulawula ukuvuthuza kwebhoyila, kodwa into yokuqala ekufuneka iqwalaselwe yinjongo yethu kanye. Enye kukulawula izithuthi. Sakuba sibale ukuvuthuza okufunekayo kwibhoyila, kufuneka sinikezele ngeendlela zokulawula ukuhamba.

Iithegi zeMveliso

Iiparameters esizaziyo: umthamo wokukhutshwa kwamanzi amdaka, uxinzelelo lwebhoyili yokusebenza, phantsi kweemeko eziqhelekileyo, uxinzelelo olusezantsi lwezixhobo zokukhutshwa kwamanzi amdaka angaphantsi kwe-0.5barg. Ukusebenzisa ezi parameters, isayizi ye-orifice yokwenza umsebenzi ingabalwa.
Omnye umba ekufuneka usonjululwe xa kukhethwa isixhobo sokulawula iblowdown kukulawula ukuhla koxinzelelo. Ubushushu bamanzi akhutshwa kwibhoyila bubushushu bokuhlala, kwaye ukuhla koxinzelelo kwi-orifice kusondele kuxinzelelo kwibhoyila, okuthetha ukuba inxalenye enkulu yamanzi iya kugqabhuka ibe ngumphunga wesibini, kwaye umthamo wayo uya kwanda. ngamaxesha angama-1000. Umphunga uhamba ngokukhawuleza kunamanzi, yaye ekubeni kungekho xesha laneleyo lokuba umphunga namanzi ahlukane, amathontsi amanzi aya kunyanzelwa ukuba ahambe nomphunga ngesantya esiphezulu, nto leyo ebangela ukhukuliseko kwipleyiti ye-orifice, edla ngokubizwa ngokuba ngumzobo wocingo. Umphumo uba yi-orifice enkulu, ekhupha amanzi amaninzi, kwaye ichithe amandla. Okukhona uxinzelelo luphezulu, kokukhona kucaca ngakumbi ingxaki yomphunga wesibini.
Ekubeni ixabiso le-TDS lifunyenwe ngamaxesha, ukwenzela ukuba kuqinisekiswe ukuba ixabiso le-TDS yamanzi kwibhoyila phakathi kwamaxesha amabini okubonayo liphantsi kunexabiso lethu elijoliswe kuyo, ukuvulwa kwevalve okanye i-aperture ye-orifice kufuneka inyuswe ukuba idlule ubuninzi. ukuguquka kwebhoyila umthamo wamanzi amdaka alahlwayo.
Umgangatho wesizwe we-GB1576-2001 uchaza ukuba kukho ubudlelwane obuhambelanayo phakathi komxholo wetyuwa (i-dissolved solid concentration) yamanzi ebhoyila kunye ne-conductivity yombane. Kwi-25 ° C, i-conductivity ye-neutralization yamanzi yesithando somlilo i-0.7 ngamaxesha e-TDS (umxholo wetyuwa) wamanzi esithandweni. Ngoko sinokulawula ixabiso le-TDS ngokulawula ukuhanjiswa. Ngolawulo lomlawuli, ivalve yedrain inokuvulwa rhoqo ukugungxula umbhobho ukuze amanzi kwibhoyila aqukuqelele kwi-TDS sensor, kwaye emva koko i-conductivity signal ifunyenwe yi-TDS sensor igalelo kumlawuli we-TDS kwaye xa kuthelekiswa ne-TDS. umlawuli. Cwangcisa ixabiso le-TDS emva kokubala, ukuba liphezulu kunexabiso elimiselweyo, vula ivalve yokulawula i-TDS ukuze uvuthe, kwaye uvale i-valve de i-TDS yamanzi yebhoyili efunyenweyo (umxholo wetyuwa) ungaphantsi kwexabiso elimiselweyo.
Ukuze kuthintelwe inkunkuma evuthuzayo, ngakumbi xa ibhoyila ikwimo yokulinda okanye umthwalo ophantsi, ikhefu phakathi kokugungxulwa ngakunye linxulunyaniswa ngokuzenzekelayo nomthwalo womphunga ngokubona ixesha lokutshisa kwebhoyila. Ukuba ngaphantsi kwendawo emiselweyo, ivalve yokuqukumbela iya kuvala emva kwexesha lokugungxula kwaye ihlale injalo de kube kukugungxula okulandelayo.
Ngenxa yokuba inkqubo yokulawula i-TDS ngokuzenzekelayo inexesha elifutshane lokubona ixabiso le-TDS yamanzi esithandweni kwaye ulawulo luchanekile, i-avareji ye-TDS yexabiso lamanzi omlilo inokusondela kwixabiso eliphezulu elivumelekileyo. Oku akuthinteli kuphela ukungena komphunga kunye nogwebu ngenxa yoxinzelelo oluphezulu lwe-TDS, kodwa kunciphisa ukuvuthuza kwebhoyili kwaye konga amandla.
