Round countercurrent cooling tower

Circular countercurrent cooling towers are widely used for circulating water cooling in various industries such as machining, chemical production, and environmental protection.

Circular cooling tower cooling principle

Hot water is pumped to the cooled water distributor system by circulating water at a certain pressure through the pump, and the water is sprayed evenly on the filler through the holes in the water distributor pipe; the dry air enters the tower from the bottom by the fan The hot water is exchanged with the air through the gap between the fillers, hot air with high humidity and high value is drawn from the top, and the cooling water drops into the water tank at the bottom of the cooling tower to be re-extracted and reused by the water pump.

Circular cooling tower features

1. Optimized structure and shape, small dimensions, low height and light weight, ventilation and heat exchange around, and it is less restricted by the installation environment.
2. The round countercurrent cooling tower is made of high-strength FRP composite material, which is resistant to aging, corrosion, and is not easy to deform and fade.
3. All metal fittings are made of llk thick steel, and the outer surface is galvanized or painted to prevent rust.
4. The circular counter-current cooling tower water distribution system is automatically driven by the pump pressure, and the water spraying efficiency is high, environmental protection and energy saving.

Installation Precautions
1. The surrounding space for the installation of circular countercurrent cooling towers is reserved for more than 1 meter.
2. Confirm the diameter and installation direction of the adapter before installing the cooling tower

Square cross flow cooling tower
The square cross-flow cooling tower is specially designed to provide cooling for large-flow circulating water. Its characteristics of large cooling and cooling flow and high cooling efficiency can be applied in the chemical, mechanical and electronic industries.

Principle of square cross-flow cooling tower

The square cross-flow cooling tower is made of glass fiber reinforced plastic. The cooling adopts two-side air inlet method. The high-performance fan on the top allows air to exchange heat with hot water through the filler on the two sides. The packing adopts a wave-shaped design on both sides of the bumps. The small wave pieces are bonded and integrated by the mounting head to make the entire cooling tower stronger and more durable. The bumps on the two sides can effectively avoid direct dripping and improve the ability of water film formation. .

Features of square cross flow cooling tower
1.Save space
The square cross-flow cooling tower uses a dedicated high-efficiency heat exchange packing, which greatly increases the heat exchange area. The structure of the tower is also optimized and the steel structure is used. The operating weight is reduced and the installation area is also reduced.
2.Excellent corrosion resistance
The tower body, water tank and panel are made of FRP material with good corrosion resistance, and a light stabilizer is added to the gel coat resin. It has good aging resistance, does not change color, and the square cross-flow cooled tower structure is steel. The steel processing is galvanized to improve the corrosion resistance of the cooling tower and make the cooling more durable.
3.Combined design
The combined design makes the engineering design and use unit selection more flexible, the manufacturer delivers faster, the installation is more convenient and fast, and during the use process, if the production process changes or increases, the cooling tower cooling It needs to be enlarged, and it is also more convenient to directly add one or more groups on the basis of the previous cooling tower.
4.Energy saving and power saving
Low wind resistance heat-dissipating filler combined with unique streamlined design, big leaf Xuanzhi high efficiency fan, greatly saving the power consumption of the motor

5.Low noise
Large Ye Xuan and streamlined fan blades, coupled with low speed operation make the fan extremely quiet

Selection considerations
1. The noise value is calculated by measuring 16 meters of the falling tower and 15 sides of the height ddm surface.
2. Pump head: When selecting the pump, please calculate the piping process, the resistance between the valve and the condenser.
3. Standard cooling capacity: 1 cold ton (1RT) is equivalent to 3900 kcal / hour, which is also equal to: 13 liters / minute / cold ton; calculation conditions: inlet water temperature 37 degrees, outlet water temperature 32 degrees, wet bulb temperature 28 degrees.

Closed cooling tower
Working principle of closed countercurrent cooling tower
This product uses two-stage cooling methods: first-stage cooling adopts air cooling, and the cooler coils are cooled by air; second-stage cooling uses air cooling and spraying, and when the ambient temperature is relatively high, it uses two-stage cooling, and air cooling At the same time, the spraying system sprays water on the surface of the cooler. When the water evaporates, it can take away the heat of the coils. The hot and humid air is recovered by the dehydrator through the top fan and discharged outside the machine to achieve the cooling effect. When the ambient temperature is relatively low, primary cooling is used. The consumption of spray water is only 0.1-0.2 ‰ per unit flow.
Application range
As the main auxiliary equipment of heat treatment industry, it is used for heat treatment of quenching medium, controlled atmosphere multi-purpose furnace, induction heating furnace, vacuum furnace, etc .; central air conditioning, forging, casting, chemical industry, food, injection molding, printing, generator set, power plant, glass melting Kiln and other fields.
