Cross Flow Closed Cooling Tower
Application:Casting, forging, air compressor, central air conditioner, ground source heat pump, printing machine
This type applies to the project which needs a large cooling range ( △T = 15-45 ℃ ) , and which place has requirements to keep low noisy and environmental protection , such as hospital and City Center.
The difference between the closed cooling tower and the open cooling tower is: The closed cooling tower exchanges heat between the cooling medium and the cooling water and air outside the tube through the coil, forming a closed circulation system, avoiding the cooling medium and the air. Contact and lead to pollution, resulting in the waste of cooling medium, equipment blockage and other failures that affect normal use.
Details
Process principle
The heated working fluid inlet from cooling coils,then the waste heat be took away by the fall down spray water and cross flow with the cold dry air which is inlet from the sides of the tower and form to saturated vapor in the process. The heat is exhausted out of tower by the top fan and the water is collected to bottom tank and circulate continuously by the special evaporator.Different from Counter Flow type, there are PVC fills inside.They per-cool the spray water, and flows in the vertical direction with cold water inlet, it will make more effective.
Characteristics
1. Low noise
PVC fills make high work efficiency and also can reduce the noisy of spray drops. Configure low noise fans.
2. Avoiding scaling
The spray water’s temperature is lower than scaling temperature, smooth flow the cooling coil and the coils are damped completely, highly reduce scaling.
3. Convenient Maintenance
Modular design is easy to assemble, disassemble and maintenance.There is a maintenance passage inside the tower.It can be repaired and cleaned without stopping the machine.They are maintenance ladder and fence,which are convenient for staff to entrance to examine and repair.
Application
Product Structure & Details
Fan--Low noise large diameter fan
Low speed fully sealed motor adopts blades with super width. The fan is composed of aluminum blades and steel wheel hub, featuring low wind resistance, high rate of air flow, low noise, high efficiency and reliable performance and so on. The protective level is IP55, suitable used for out door.
( Blade options: aluminum alloy, aluminum alloy hollow, carbon fiber, polythylene )
Outer Sheel--Imported Aluminum-zinc Plate
The imported Aluminum-zinc plate is one of the best corrosion resistant materials at present, with life span 3-6 times than common galvanized steel. And has follwing advantages such like high strength and toughness, good heat resistance and beautiful appearance, etc.
( Shell material options: Aluminum-zinc plate, SuperDyma, 304 Stainless steel )
Cooling Coils--Different choices of material
Red Copper Coils: Good heat exchange effect, high antifreeze requirements. Pressure design 1.6Mpa.
Stanless Steel Coils: Pressure design 2.5Mpa, corrosion-resistance ability, cheaper.
Adopt advanced automatic welding equipment to ensure no leakage.
PLC--Brand:Siemens, Schneider
PLC intelligent control, local/remote control, can be adjusted according to different working conditions.
PVC Fills--High efficiency PVC material
High quality PVC material may effectively transfer heat and reducing the water flow to save energy resources.
( Air window options: steel louver type, pvc honeycomb type )
Spraying System--Efficient spray system
Spraying Nozzle: The high-efficiency water spary system provides important guarantee for the cooling capacity. Spray water is evenly distributed, and the spray nozzles are easy to clean and replace.
Spraying pump: Special circulating spary pump with the protective level is IP55, no leakage, long life span.
Auxiliary--Choose depend on your needs
Main circulationg pump
A pump with a backup, failure occurs the backup pump can automatically put into operation high efficiency. Low-vibration, low-noise and high energy efficient.
( Motor options: Simens, ABB, Datang, Dongyuan )
