SF-25T CLOSED COOLING TOWER

Closed cooling tower working principle diagram

1) Closed cooling tower working principle :

Air cooling parts: working fluid (softened water or other liquid) in the closed cooling tower circulation of coil, fluid heat after being absorbed by the coil pipe wall, through the fan at the top of the wall of the heat outside.

Water-cooled parts: when the fluid temperature is too high (more than) when setting the temperature of the spray system will start automatically spray pump water spraying pipe wall and form a water film in damp and hot, absorb a lot of heat by evaporation (latent heat of evaporation). Part of spray water into steam, was taken away by the air flow, not being dripping water evaporation in the sump tank for the next cycle. The fluid flow in the coil closed loop, in theory, no consumption. Spray water consumption is only for the unit flow rate of 0.1 0.2%

3)  Closed cooling tower technical performance

Parts of host:

A),Support: made of 304 stainless steel Angle steel and channel steel is advantageous for the daily maintenance and fault maintenance operations.

B),Shell:Cooling tower shell plate using 2 mm thick 304 stainless steel plate production.

C),Cooler: the cooler used gb T2 acid were made with copper, proprietary anti-freezing type structure design of the structure for the same boat, when the equipment out of service guarantee will be circulating water cooler out clean, the connection between the copper pipe and the water bag with silver electrode welding.

    D),Exhaust system:ventilation system is mainly composed of intake grille, fan and protective cover, etc; Fan blades for aluminum alloy material, motor adopts is three. Intake grille with push-pull type design and installation, convenient disassembly.

     E),Spray system: spray system are connected by a spray pumps, pipe, spray the top. When the temperature more than set temperature, the system automatically open spray system control. Connection pipe and pipe fittings of stainless steel material production. Spray pump adopts closed cooling tower for small power, large flow, low head pump.

    F),Dehydrator: PVC efficient dehydrator, made of high-quality raw materials to control spray evaporation of water splash, the water flowing rate of less than 0.5%.

G),water tank: set water tank made of 304 stainless steel spray water added to automatic control by floating ball valve, the tank bottom side is equipped with drainage outlet, convenience of mixed fouling cleaning.

   The parts of auxiliaries:

a),Circulation tank: capacity of 1 m3, 304 stainless steel material, thickness of 2 mm, made of special mold tank plate welding on the tank is equipped with liquid level observation and alarm system with fault rate

b),Circulating pump groups: flow rate of 70 m3 / h, head of 18 m, 6 kw power. The pump can switch to use each other. Control method for manual control. Each pump before and after loading a butterfly valve.

c),Electric cabinet:control part including spray water pump motor, fan motor, the circulating water pump group chain control and temperature digital display and measurement and spray water and electricity heating system.

Advantages of Cooling tower:
1. Cooling medium is fully closed circulation in case that the debris into cooling system and to prevent the loss of cooling medium.
2. Soft water is not easy to scale, not blocking the pipeline.
3. Using cold water and spray water evaporation endothermic double cooling method with a high cooling efficiency.
4. The device has the advantages of small size, convenient movement and placement.
5. Using of automatic intelligent control, according to the requirements of the operating conditions automatically change the cooling mode.
