Vhura-loop vs Yakavharwa-loop Cooling Towers: Chii chiri Nani?

 

 

 

I. Vhura-loop Cooling Towers: Yakaderera-inodhura uye Yakakwirira-inoshanda zvakanaka Heat Exchange, Inokodzera Zvinodiwa Zvekare Kutonhodza.

 

Chinhu chakakosha chekuvhura-loop cooling towers ndechekusangana kwakananga pakati pemvura inotonhorera nemhepo: mvura inotenderera inosaswa pafiller kuburikidza nespray system, uye inobata mhepo yakaunzwa ne fan mu countercurrent/crossflow kuti iwane evaporative heat exchange and convective heat exchange. Mvura yakatonhodzwa inoyerera yakananga kumidziyo yekutonhodza (yakadai sechiller, process reactors).

Yayo yakakosha mabhenefiti anotarisa pane "yakanyanya kushanda uye yakaderera mutengo":

 

 

 

 

 

Zvakadaro, akavhurika-loop masisitimu ane zviri pachena:

 

Ngozi huru yekusvibiswa kwemhando yemvura: kutenderera kwemvura kunoratidzwa zvakananga kumhepo, huruva uye tupukanana, zvinotarirwa kuyera uye kuora kwemidziyo mapaipi. Zvinodikanwa kugara uchiwedzera mascale inhibitors nemishonga inouraya utachiona, zvichiita kuti uwedzere mari-yenguva refu yekugadzirisa;

Kurasika kukuru kwemvura: kuparara kwe evaporation + drift loss account inosvika 1.5%-3% yehuwandu hwemvura inotenderera, iyo inogumira munzvimbo dzisina mvura kana zviitiko zvine zvinodiwa zvekuchengetedza zvakatipoteredza;

Kusagadzikana kwetembiricha: kukanganiswa zvakanyanya netembiricha uye mwando, nekushanduka kukuru kwetembiricha yemvura inobuda kunze panguva yekukwira-tembiricha yezhizha, zvichiita kuti zviome kuzadzisa zvinodiwa zvekutonhodza zvemidziyo chaiyo.

II. Yakavharwa-loop Cooling Towers: High Stability uye Low Maintenance, Inokodzera Mamiriro Ekushanda Akanyanya

 

Yakavharwa-maruzha ekutonhodza shongwe anotora yakavharwa yekutsinhanisa kupisa: kugadzira mvura/midziyo yekutonhodza mvura kuti itonhodzwe inotenderera mumakoiri akavharwa, uye kunze kwemwaya mvura nemhepo zvinopfuura nemumakoiri mucrossflow/countercurrent, zvichiwana shanduko isina kunanga yekupisa nepamadziro echubhu. Mvura iri mumakoiri haisi kusangana nenyika yekunze panguva yese iyi.

Yayo yakakosha mabhenefiti anotarisa pane "kugadzikana uye kuvimbika":

Kuchena kwemvura yakakwira: kutenderera kwakavharwa kunodzivirira zvachose kuyera, ngura uye kusvibiswa kwehutachiona, uye inogona kutonhorera zvakananga michina (yakadai semaseva epa data, marejikita emishonga), kuwedzera hupenyu hwesevhisi yemidziyo uye kuderedza zvakanyanya mutengo wekugadzirisa pombi;

Kusimba kwekushanda kwakasimba: tembiricha yekubuda kwemvura yekubuda haina kukanganiswa nenharaunda, ine tembiricha musiyano inodzorwa mukati me ± 1 dhigirii, inokodzera mamiriro anoda yakanyanya tembiricha chaiyo;

Mvura yakakosha-inochengetedza mvura: kudonha kushoma kwemvura kunoitika mumvura yekupfapfaidza yekunze, ichichengetedza mvura inodarika 90% kana ichienzaniswa neshongwe dzakashama, ichizadzisa zvinodiwa nemvura{2}}nzvimbo dzinoshomeka kana mitemo yekuchengetedza nharaunda;

Wide applicability: inogona kushandura pakati pe "evaporative cooling + air cooling" modes, uye inogona kushanda chete nekutonhora kwemhepo munguva yechando nekuvhara iyo spray system, ichiwedzera kuderedza simba uye kushandiswa kwemvura.

Izvo zvakanyanya kuipa zveakavharwa{0}}loop masisitimu ndeaya:

Mutengo wekutanga wakakwira: magadzirirwo akaita semakoiri akavharwa uye-zvinoita zvekuchinjisa moto zvikamu zvinoita kuti kutenga michina kudhure 50% -80% kudarika shongwe dzakavhurika;

Kunyanya kudzika kupisa kwekutsinhanisa kunyatsoshanda: zvisina kunanga kupisa kupisa kunoguma mukusvika tembiricha kazhinji ye4-6 dhigirii, uye vhoriyamu yemidziyo yakakura kana uchibata mutoro wakafanana, unoda imwe nzvimbo yekuisa.

 

 

III. Sarudzo Sarudzo: Core Dimension Kuenzanisa Kubva pane Mamiriro

 

 

Kuenzanisa Dimension	Vhura-loop Cooling Tower	Yakavharwa-loop Cooling Tower
Kutanga Investment	Yakaderera (yakareruka chimiro, hapana yakavharwa coil)	Yakakwirira (kusanganisira coils, sealing system)
Heat Exchange Efficiency	Yakakwira (yakananga kuonana, kusvika tembiricha 2-3 degree)	Pakati (kusangana kusinganangi, kuswedera tembiricha 4-6 dhigirii)
Mvura Yakanaka Impact	Inowanzoita kusvibiswa, kurapwa kwemvura nguva dzose kunodiwa	Hunhu hwemvura hwakachena, hapana kuyera kana njodzi yekuora
Operating Cost	Yakakwira (kushandiswa kwemvura + mutengo wemakemikari)	Yakaderera (mvura-inochengetedza + gadziriso shoma)
Tembiricha Kugadzikana	Varombo (zvakanyanya kukanganiswa nenharaunda)	Yakanakisa (tembiricha musiyano mukati ± 1 degree)
Applicable Scenarios	Maindasitiri akakwira-mutoro, zvinodikanwa zvemhando yemvura yakaderera, matsime emvura anokwana	Midziyo yechokwadi, zvinodiwa zvemhando yepamusoro yemvura, -nzvimbo dzinoshomeka

 

 

IV. Mhedziso: Hapana Hukuru, Chete Mamiriro Ekugadzirisa

 

Yakavhurika-loop cooling towers "inodhura-inoshanda sarudzo", inokodzera mamiriro emazuva ese emaindasitiri ane matsime emvura akakwana, mitoro mikuru yekutonhodza uye zvinodiwa zvemhando yemvura yakaderera (semagetsi ekutenderera kwemvura, yepakati pemhepo inotonhodza mvura), kuwana yakakwirira-kugona kuchinjanisa kupisa nemutengo wakaderera; akavharwa-loop cooling towers "isarudzo yakavimbika", yakakodzera kutonhodza midziyo chaiyo, mvura-nzvimbo shoma, zvinoda kuchengetedzwa kwezvakatipoteredza zvakanyanya kana mamiriro ekushanda akaomarara ane-kushanda kwenguva refu, kuchinjana mari yekutanga kuti ishande zvakagadzikana uye mari shoma yekuigadzirisa.

                                                

Pfungwa huru yekusarudza ndeyekuenzanisa "zvinodiwa uye mutengo": kana zvakakosha zvakapihwa kudzora mari yekutanga uye kutsvaga yakakwirira-inotakura kupisa kupisa, kuvhura{1}}loop kuri nani; kana simbiso ikaiswa pakugadzikana kwekushanda, kuchengetedza mvura nesimba, kana kuchinjika kumamiriro ekushanda chaiwo, kuvhara-loop isarudzo isingadzivisiki. Mukushandisa, mamwe mabhizinesi anotorawo "open-loop + closed-loop" akasanganiswa masisitimu kuti aenzanise zvinodiwa zvekutonhodza zvemalink akasiyana uye kuwana chiyero chakakwana pakati pekuita basa nemutengo.
