Kwazvo Kushanda Kweduta Yakavharwa Inotonhodza Towers Muchando

 

 

Nheyo yekushanda yakavharwa yedunhu inotonhorera tower munguva yechando iri mukatianti -kudzivirira kutonhora, kuoma/kunyorova kwekuchinja, kugadzirisa parameter, kuongorora nekugadzirisa. Izvo zvinodikanwa kudzivirira kutonhora uye kutsemuka kwemakoiri nemapaipi paunenge uchiona kutonhora kwakanaka uye kuchengetedza kwemidziyo. Urongwa hwekushanda huchagadzirwa zvinoenderana nemaitiro ekushanda, ambient tembiricha uye masisitimu ehurongwa.

 

 

 

1. Pre-Winter Anti{2}Gadziriro Yechando (Inofanira Kuitwa Nguva Yechando isati yasvika)

System Insulation Reinforcement

Putira shongwe shell, kupisa kupisa makoiri, inlet/outlet pombi, pfapfaidzo mapaipi, mavharuvhu uye pani yekuunganidzira mvura nedombo reshinda kana polyurethane insulation layer inodarika 50mm, uye isa mushonga wekusapinda mvura pachikamu chekunze. Isai matepi ekudziya-emagetsi ekudziisa pamapaipi akaiswa pachena ane tembiricha yekudzora tembiricha yakaiswa kuti ishande pa 4 degrees uye yomira pa8 degree, uchitarisa pazasi-paipi dzepaipi nemakona akafa.

 

Anti-Gadziriro Yekumisa Solution

Wedzera ethylene glycol kana propylene glycol antifreeze kune kutenderera kwemukati (process water side). Rongedza kunyura zvichienderana netembiricha yepasi (eg. 30% ethylene glycol ye -15 madhigirii nharaunda), kuve nechokwadi chekuti nzvimbo yekutonhora yakadzika 5-10 madhigirii pane ambient tembiricha. Tsiva ne corrosion inhibitor inoenderana.

 

Kudhiraivha nekuchenesa

Pamidziyo yakavharwa kwenguva yakareba, vhura mavharuvhu ese ekudhiraivha neanobuda, uye nyatsochenesa mvura inenge yasara mumakoiri, pfapfaidza mapaipi uye pani yekuunganidza mvura nemweya wakadzvanywa kuti usaomesa nechando. Nekuvharika-kwenguva pfupi, chengetedza kuyerera kunoramba kuchiitika mukati mekutenderera kwemukati.

 

Otomatiki Kudzora System Kumisikidza

Syakadzika-aramu yetembiricha painodzosa tembiricha yemvura Iri pasi pe5 kana kuenzana ne5 degrees, yakabatana nekudzikisa frequency/kudzima kwefan uye kutanga/kumira pombi yekupfapfaidza. Shongedza pani yekuunganidzira mvura nekudziya kwemagetsi uye fluid level interlock kudzivirira kupisa kuoma.

 

 

 

2. Anti-Kuomesa uye Parameter Optimization Panguva Yekushanda (Core Operation)

 

Internal Circulation (Process Water Side): Chengetedza Kuyerera uye Kugadzikana Kwekushisa

 

Hapana kuvhara kana kuyerera kwekucheka

Chengetedza hushoma hwemukati wekutenderera kuyerera mwero (Kukura kupfuura kana kuenzana ne30% yedhizaini yekuyerera) kunyangwe pasi pemutoro wakaderera. A bypass valve kana yekubatsira pombi inogona kushandiswa kudzivirira mvura isingamire mumakoiri.

 

Kudzora tembiricha

Dzora kudzoka kwekushisa kwemvura pa8-15 degrees. Dzima kana kuderedza kumhanya kwefan pane tembiricha yakaderera kuderedza kupisa kwemhepo inotonhora. Mukupisa kwakanyanya kwakadzika, pfuura shongwe yekutonhodza uye shandisa nzira yekupisa kupisa kuchengetedza tembiricha yemvura.

 

Antifreeze monitoring

Tarisa antifreeze yekumisikidza uye chando poindi vhiki nevhiki, uye dzodza nenguva kuti udzivise kutadza nekuda kwekudonha kwekusungwa.

 

Kutenderera Kwekunze (Spray Water Side): Tembiricha-Inodzorwa Kutanga/Kumira uye Yakaoma/Kunyorova Kuchinja

 

Wet operation

Normal kumwaya kana ambient tembiricha Yakakura kupfuura kana kuenzana ne5℃. Gadzirisa pombi yekupfapfaidza kana tembiricha yemvura yekudzoka yadonha kusvika 5-7℃. Isa magetsi ekudziya mugango rekuunganidza mvura kuchengetedza tembiricha yemvura Yakakura kupfuura kana kuenzana ne4 degree.

 

Dry operation

Kana ambient tembiricha ichienderera<0℃, completely drain the spray system, turn off the spray pump, and use only fan air cooling (full dry mode) to completely eliminate the risk of spray water freezing.

 

Kupfapfaidza nguva nenguvaKana

kupfapfaidza kunodiwa, shandisa-kutenderera kwekutanga/kumira kwenguva pfupi (semuenzaniso mhanya maminetsi gumi, mira maminitsi makumi maviri) woisa insulation yekudzivirira kupisa pakupfapfaidza mapaipi.

 

Fan uye air volume kugadzirisa

Shandisa variable frequency control. Deredza kukurumidza kana kumhanya nguva nenguva pane tembiricha yakaderera. Kune dzakafanana shongwe dzakawanda, tarisa mutoro wekushanda kuti uwedzere kupisa mutoro uye kubuda kwemvura tembiricha yeshongwe imwe chete uye kuderedza njodzi dzechando.

 

 

 

3. Shutdown uye Restart Specifications

Kuvhara-kwenguva pfupi (Zvisingasviki kana kuenzana nemaawa 72)

Chengetedza pombi yemukati yekutenderera ichimhanya, vhura iyo bypass, chengetedza tembiricha yemvura Yakakura kupfuura kana yakaenzana ne5 degree; dhiraivha system yekupfapfaidza uye chengeta kupisa kutsvagisa insulation.

 

Long-term shutdown (>maawa 72)

Nyatsodhonza uye bvisa kutenderera kwemukati uye kupfapfaidza system nemhepo yakamanikidzwa, vhara mavharuvhu ese uye chisimbiso zvakanaka. Kadikidiki keantifreeze inogona kubaiwa mumakoiri kuti dzidzivirire.

 

Restart maitiro

Kutanga tarisa kutendeseka kwekudzivirira, kupisa kwekutsvaga uye mapaipi. Tanga iyo yemukati inotenderera pombi zvishoma nezvishoma, simudza tembiricha zvishoma nezvishoma kusvika pamusoro pe10 degree, wobva wabatidza kupfapfaidza kana feni zvinoenderana neambient tembiricha kudzivirira kuvhunduka.

 

 

 

 

4. Kuongorora Kwezuva Nezuva uye Kuchengetedza (Inodiwa Zuva Nezuva)

Parameter monitoring

Rekodha kudzoka tembiricha yemvura, kudzvanywa uye ikozvino kwese kwemaawa maviri kuti uone tembiricha yemvura Yakakura kupfuura kana kuenzana ne5℃uye yakatsiga kudzvanywa.

 

Kuongorora{{0}kutonhora kwechando

Ongorora maseiri ekudzivirira, matepi ekudziya uye pani yekuunganidza mvura zuva nezuva. Nyusa ice nemvura inodziya kana yawanikwa; kudira mvura inopisa kunorambidzwa zvachose. Bvisa mazaya echando pamhepo inopinza uye mafirita kuitira kuti pave nemhepo.

 

Kutarisira kunaka kwemvura

Mvura inowanzokura muchando. Chenesa mafirita vhiki nevhiki, edza pH uye kuoma pamwedzi, uye dhonza uye kuzadza mvura nenguva kuitira kudzivirira kuvharika nekuora.

 

Kugadziriswa kwemagetsi

Tarisa kudzivirira mvura uye anti -kutonhora kuita kwemotor, frequency converters uye control cabinets kuti uone kutangirwa kwakaringana nekudzikira.

 

 

 

 

5. Kuchengetedza uye Simba{1}}Kuchengetedza Mapoinzi Akakosha

 

Isa pamberi pakaoma modhi pane yakaderera tembiricha kuderedza kupfapfaidza simba rekushandisa uye nechando njodzi. Matanidza feni uye pombi frequency ine mutoro kuderedza kushandiswa kwesimba.

 

Gadzira chirongwa chekukurumidzira chinotonhora. Rega kupfapfaidza mukupisa kwakanyanya kwakadzika, simbisa insulation uye kudziyisa kwemukati kutenderera, uye shandisa yenguva pfupi yekudziya yemagetsi kana zvichidikanwa.

 

 

Kushanda yakavharwa yedunhu inotonhorera shongwe munguva yechando inotora anti-kuomesa semutsetse wepasi, kuyerera semusimboti, uye otomatiki control senzira. Kuburikidza nekudzivirira, kutsvaga kupisa, kuomesa/kunyorova, kudzora parameter uye kuongorora nguva nenguva, kukuvadzwa kwemidziyo kubva muchando kunogona kudziviswa, kuita basa rakachengeteka, rakanaka uye rinochengetedza simba-.
