Antoy Sankaepektiboan ya Klase na Cooling Tower?

 

Diad panmoria na manunan prinsipyo na panagsalat na petang, say cross-flow closed-circuit cooling tower et mangaagamil na"cross-air flow + closed-circuit circulation"desinyo: say danum ya pampalamig et onaagus ed loob na saray akasara ya tubo na coil ya anggapoy direktan pakapitongtong ed dagem ed paway, bangta say dagem ed paway et ondalan ya pabitay ed saray tubo na coil tan say spray water layer, ya manporma na three-phase heat exchange system (gas-liquid-solid). Sayan istruktura et mamaaligwas ed heat exchange area utilization rate na masulok ya 30%, tan say pandumaan na temperatura na panagpaliis et nayarin nakontrol ed loob na 5-8 degree, ya mas maong nen say 8-12℃na open-circuit cooling towers. Balet, say closed-circuit circulation et sigpot ya manresolbe ed saray problema na scaling, corrosion, tan polusyon ed kalidad na danum ya misiglaotan ed saray open-circuit towers. Say siklo na panaglinis na saray tubo na coil et pinalaknab ed 12 bulan, ya say heat exchange efficiency attenuation rate et kulang ed 5%. Diad pidumaan, saray open-circuit towers et nayarin makaeksperiensya na heat exchange efficiency ya anggad 20% ed loob na anem bulan lapud scaling.

 

 

 

No nipaakar ed inkaepektibo na enerhiya, say cross-flow closed-circuit cooling tower et walaan na saray prominentin bentaha. Say cross-flow design to et mamapaabeba ed static pressure loss na fan, tan say onsusuportad high-efficiency variable-frequency fan et makatipid na 25%-30% ya mas dakel ya enerhiya nen saray fan na tradisyonal ya counter-flow cooling towers. Niarum ni, sayan modelo et sarag ton automatikon i-adjust so peles na bentilador tan say igapo/itunda na spray pump unong ed aktual ya cooling load. Say coefficient of performance (COP) ed silong na partial load conditions et nayarin onabot ed masulok ya 4.5, bangta say COP na open-circuit cooling towers et kaslakan ya 2.8-3.2 labat. Parad 1,000 m3/h ya agos na cooling water, say cross-flow closed-circuit cooling tower et makatipid na masulok ya 100,000 yuan ed gastos ed kuryente kada taon, ya sigpot ya ontutumbok ed saray kakaukolanen ed panagpreserba na enerhiya tan panagbawas na konsumo ed industriyal a sektor.

 

 

Diad panmoria na O&M tan say bilay na serbisyo, say cross-flow closed-circuit cooling tower et walaan na mas abeban gastos. Say closed-circuit circulation et mamapaabeba ed konsumo na saray kemikal parad kalidad na danum, ya say gastos ed kemikal et mankantidad labat na 1/3 na saray open-circuit towers. Diad saman met a panaon, saray akasara ya tubo na coil et anggapoy peligro na pakabaraan, kanian nabawasan so O&M workload na 60%. Say adesinyo ya bilay na kagawaan et nayarin onabot ed 20 taon, ya 8-10 taon ya mas andukey nen say open-circuit towers. Niarum ni, say cross-flow structure to et manresulta ed abeban katagey na tori, ya mamapaabeba ed pankaukolan na espasyo parad pangipaalagey na 25%, kanian mas matukoy itan parad saray compact ya layout ed loob na saray talyer odino diad saray atep.

 

 

Nepeg ya imanoen ya say inmunan gastos ed cross-flow closed-circuit cooling towers et 15%-20% ya mas atagey nen say open-circuit towers. Balet, diad panamegley na pakatipid ed gastos ed enerhiya tan gastos ed O&M, say pinansyal ya pinansyal et nayarin nabawi ed loob na 2-3 taon. Parad saray simplin senaryo ed industriya ya abeba so karga tan atagey so konsentrasyon na dabok, saray open-circuit tower et walaan ni na pigaran bentaha ed gastos-epektibo. Anggaman ontan, manlapud perspektibo na andukey a panaon na operasyon tan say manunan pankaukolan parad atagey a -epektibon panagpaliis, say cross-flow closed-circuit cooling tower so sankaabigan ya pilien natan ed industriyal a lawak.
