Fibre Reinforced Plastics (FRP) Towers:
Amfani da FRP towers yana ci gane da yawan mafi yawa da kuma karfin da yake da process plants da suka kawo babban cooling towers da suke amfani da FRP.
Abubuwan da suka buƙata a FRP cooling towers shine:
Mafi girman yawa
Da mafi girman da take da kan chemical water, saboda haka amsa da ita yana da yawan mafi yawa a cikin pH range.
FRP towers suna da mafi girman da take da kan fire, saboda haka ba a tabbas da take da fire protection system.
Wadanda ake kunne a cikin lokaci da kuma take da lokacin mafi yawa a lokacin daɗi.
Abubuwan da ke Cikin Cooling Tower
Rayuwar da cooling towers mai kyau ke da shi yana da 20 zuwa 25 shekara. Akwai abubuwan da dama a cikin cooling:
Abubuwan da za a kawo:
Air moving component (draft fans)
Packing materials (Fills)
Hot water distribution system
Louvers
Drift eliminators
Abubuwan da ba za a kawo ba/Strukturale Mai Tsauri
Cold Water Basin
Bayanin da yawan mafi girman abubuwan da ke cikin cooling tower da kuma mataimakansa suna cikin haka:
Packing Materials Coling Tower
Shi ne mafi girman abubuwan da ke cikin cooling towers, saboda haka an yi amfani da Splash Fills da kuma Film fills don zama mafi girman cooling effective da cooling tower.
Splash Fills:
Towers suna da patterns horizontal da vertical staggered don splash hot water da ke samu daga tsohon distribution deck. Splash an yi amfani da shi don divide hot water a fine water droplets da kuma zama mafi girman surface area da ke da air da water.
Film Fills :
Wadannan shine plastic corrugated sheets wanda ake koyar da su don nuna honeycombed appearance. Wurare da ake amfani da shi a film fill shine PVC, Polypropylene.
Cooling Tower Hot Water Distribution System
Shi ne don distribute hot circulating water a cikin cooling towers don sauke hot process water. An yi amfani da distributing basin, headers, distributing arms, spray nozzles, flow regulating valves.
Cooling Tower Cold Water Basin
Cold water basin a kasar da tower yana da aiki don collect cooled water da kuma supply shi a cikin suction of circulating water pumps.
Capacity of the basin should be to hold the 3 times of circulating water flow rate in gpm.
Cooling Tower Fan
Fans an yi amfani da shi a induced draft cooling towers. Wurare da ake amfani da shi a blade shine FRP, Aluminum da kuma hot-dipped-galvanized steel.
Louvers
Aiki da louver a cross flow cooling tower shine
Don equally distribute the air flow to the fills.
It helps in retaining the water inside the tower.
Louvers ba a buƙace a counter flow cooling tower ba.
