Iyo Yakavharwa-Circuit Cooling Tower Inoshanda Sei?
A yakavhara{{0}circuit cooling tower(inonzi shongwe yekutonhodza yakavharwa kwenguva pfupi) chishandiso chekutonhodza chepamusoro-chinosanganisa tubular heat exchanger neshongwe yekutonhodza. Mhedzisiro yaro iri mukuwana kufambiswa kwekushisa kuburikidza nemusanganiswa we "yakavharwa yepakati kutenderera" uye "yakavhurika pfapfaidzo kupisa kwekuchinja"{2}}haingodzivise svikiro rekutonhodza kubva pakusvibiswa asiwo inobvisa kupisa nemazvo, zvichiita kuti ishandiswe zvakanyanya mufiriji yemuindasitiri, kutonhora kwemidziyo, pakati pemhepo, uye zvimwe minda. Maitiro ayo ekushanda anogona kukamurwa kuita matatu epakati malink:mukati mepakati kutenderera, yekunze kupfapfaidza kupisa kuchinjanisa, uye mhepo vhoriyamu regulation rubatsiro, ine yakazara mashandiro logic yakatarisana ne "indirect heat exchange uye evaporative kupisa disipation".
Yemukati Yakavharwa Yepakati Kutenderera: Kufambiswa kweCore Heat Carrier
Hunhu hwakakosha hweshongwe yekutonhodza yakavharwa ndeyekuti inotonhodza (inowanzo mvura yakapfava, ethylene glycol solution, kana mvura yakakosha yekutamisa kupisa) inotenderera mucoil loop yakavharwa, isingabatanidzwe nemhepo yekunze kana kupfapfaidza mvura-inova musimboti wekuva "kuvharwa".
Panguva yekushanda, iyo inopisa inofanira kutonhodzwa (semuenzaniso, yakakwirira-kudziya kwepakati kubva kunotonhora kana mareactor emuindasitiri) inounzwa kumakoiri ekuchinjana kupisa kwenhare yakavharwa yekutonhodza nepombi inotenderera. Iyo yepakati inoyerera ichienderera mukati memakoiri, ichiendesa kupisa kwainotakura kumadziro ekoiri.
Macoil anowanzo kugadzirwa nesimbi isina tsvina, titanium alloy, kana copper alloy, ine yakanakisa yekupisa conductivity uye corrosion resistance, inogonesa kukurumidza kupisa conduction kubva pakati kusvika kumadziro coil. Kana kupisa kwaitwa, -kudziya kwepakati kunodzokera kumudziyo wakatonhodzwa kuburikidza nekoiri kuti ienderere mberi nekusveta kupisa, zvichiita kutenderera kunoramba kuvharika.
Kiyi yekubatanidza iyi kuchengetedza kusimba kwechiuno kudzivirira kudonha kwepakati kana kupinza kwemhepo, izvo zvinogona kukonzera kuderera kwepakati uye kupera kwepombi. Naizvozvo, sisitimu iyi inowanzo gadziridzwa tangi rekuwedzera (kudzikamisa kushanduka kwesimba), make-pombi (kuwedzera kurasikirwa kwepakati), uye sefa chaiyo (kubvisa tsvina).
External Spray uye Evaporative Heat Exchange: Heat Transfer kune Atmosphere
Kunze kweshongwe yekutonhodza yakavharwa kunotora chimiro chakavhurika, chinobvisa kupisa kubva mumakoiri kuburikidza nekupfapfaidza kwemvura yekupfapfaidza uye mhepo convection-iyi ndiyo yepakati heat dissipation link, yakakamurwa kuita matanho maviri: "spray mvura kutenderera" uye "evaporation + convection heat exchange".
Spray Water Circulation
A sump inoiswa pazasi peshongwe. Pombi yekupfapfaidza inodzvanya mvura inotonhora iri musump uye inomwaya zvakaenzanirana pamusoro pekunze kwemakoiri ekutsinhanisa kupisa kuburikidza nepamusoro pfapfaidzo mudziyo, ichigadzira firimu remvura rakafanana. Mvura yekupfapfaidza inobata zvizere madziro ekunze emakoiri, inotora kupisa kunotamiswa nemadziro, uye yobva yadzokera mu sump mushure mekukwira kwekushisa, ichipedzisa kutenderera kwemukati kwemvura yekupfapfaidza. Iyo sump inowanzo shongedzerwa nemhando yemvura inodzikamisa dosing mudziyo kudzivirira kuyera uye kukura kwehutachiona mumvura yekupfapfaidza, iyo inogona kukanganisa kupisa kwekuchinjana kushanda.
Evaporation + Convection Heat Exchange
Axial flow fan inoiswa pazasi kana padivi peiyo yakavharwa inotonhorera tower. Kana iyo feni ichishanda, inokwevera mumhepo inodziya tembiricha kubva kunze kweshongwe, uye mhepo inopfuura ichikwira kumusoro kuburikidza nemukaha uri pakati pemakoiri nefirimu remvura. Mhando mbiri dzekutsinhana kupisa dzinoitika panguva ino: kutanga,zvinonzwisisika kupisa kuchinjanisa{{0}mhepo inobata zvakananga-firimu remvura rinopisa, richifambisa kupisa kuburikidza nekusiyana kwetembiricha; chepiri,latent heat exchange-chikamu chemvura yekupfapfaidza chinoputika pasi pekuyerera kwemhepo, ichitora huwandu hukuru hwekupisa kwakadzikama kwemhupo (inoverengera 70% -80% yekubvisa kupisa kwese), izvo zvinokurumidza kuderedza kupisa kwekoiri kunze kwemadziro.
Mhepo inopisa uye yakanyoroveswa inoburitswa kubva pamusoro peshongwe, ichibvisa kupisa kwakawanda, nepo mvura yekupfapfaidza isina mhepo inodonha ichidzokera kune sump kuti idzokororwe. Huwandu hudiki hwekurasika kwe evaporation hunobhadharwa nekuwedzera mvura yakachena.
Air Volume Regulation uye Mashandiro Ekubatsira: Kukwidziridzwa kweKushanda Kwekushanda
Kuti uenderane nemitoro yakasiyana uye mamiriro ezvakatipoteredza, shongwe dzekutonhodza dzakavharwa dzakagadzirirwa kudzora vhoriyamu yemhepo uye masisitimu ekubatsira kuona kugadzikana kwekushanda uye kushanda nesimba:
Variable frequency fan control: Inogadzirisa otomatiki kumhanya kwe fan (kana nhamba yevanoshanda mafeni) zvichibva pane tembiricha yepakati painobuda yekupisa yekutsinhana makoiri. Kana mutoro wekutonhora wakadzikira, kukurumidza kwe fan kunoderedzwa kuchengetedza simba; kana ambient tembiricha yakawandisa (semuenzaniso, muzhizha), kumhanya kunowedzerwa kuwedzera huwandu hwemhepo uye kuve nechokwadi chekupisa kupisa.
Anti-midziyo yekuomesa nechando: Munzvimbo dzinotonhora kana kuti munguva yechando-yakatakura zvinhu zvishoma, mukati memakoiri anogona kugwamba nechando nekuda kwekuderera kwekushisa. Iyo sisitimu inoshongedzerwa nemagetsi ekutsvaga, kutsvagisa mhepo, kana kutenderera bypass mudziyo kuchengetedza tembiricha yepakati pamusoro pechando; Zvichakadaro, pfapfaidzo hurongwa anogona chinja kuti "yakaoma kushanda" (kumisa pfapfaidzo, kuvimba chete mhepo convection nokuda kupisa exchange) kudzivisa kukanganisa shongwe kunokonzerwa nechando pfapfaidzo mvura.
Demister design: Demister yakaiswa pamusoro peshongwe, iyo inogona kutora madonhwe madiki emvura mumvura yekupfapfaidza (ine chiyero chekutora chinodarika 99%). Izvi hazvingodzikisi tsvina yemvura chete asiwo zvinodzivirira madonhwe emvura kubva pakubuda nemhepo, izvo zvinogona kukonzera mwando kana ngura munzvimbo yakapoteredza.
Pfupiso yeOall Working process
Kushanda kwenzvimbo yakavharwa-inopopodza nhare inogona kupfupikiswa se: svikiro rinopisa rinopinda mumakoiri → kuitisa kupisa nemadziro emakoiri → pfapfaidza mvura inotora kupisa → mweya unobuda uye wotakura kupisa kure → zvinodzoka zvakatonhodzwa.
Iyo inopisa inopisa inoyerera mumakoiri akavharidzirwa, uye kupisa kunotamirwa kuburikidza nemadziro evhavha kune ekunze spray water film; mhepo inounzwa nefeni inobata firimu remvura, richitakura kupisa kunze kweshongwe kuburikidza nekubuda uye convection; iyo yakatonhodzwa yepakati inodzokera kumidziyo yekudzokorodza, nepo mvura yekupfapfaidza inotenderera yadzokororwa mukati meshongwe ine shoma shoma yekurasikirwa evaporation inowedzerwa.
Dhizaini iyi inoramba iine mukana wepamusoro-unyanzvi hwekunyudza kupisa kweshongwe dzakavhurika dzekutonhodza uku ichidzivirira kusvibiswa uye kuyera nyaya dzinokonzerwa nekusangana kwakananga pakati pekutonhodza nekunze kwenyika, kuzadzisa zvinangwa zviviri "pamusoro-kugona kupisa kwekubvisa + kuchengetedzwa kwepakati".
