How should cooling tower fill be selected?

As the primary center of circulating water heat dissipation in industrial production, cooling towers affect the cost and power of industrial production in my country. Improper use of cooling towers in industrial production will result in untimely heat dissipation of equipment, stagnation of production, and danger of excessively high water temperature. The cooling tower packing is the primary factor to promote the water and heat cycle, therefore, it is necessary to choose high-quality cooling tower packing.

1. Specification size of cross-flow cooling tower

The distance between the top of the cooling tower fill and the lower end of the fan should be 1.2 times the diameter of the fan.

2. Specification Angle of Counterflow Cooling Tower

1. When building a counter-flow cooling tower, the angle between the top of the packing and the airflow section should be controlled within 90 degrees, a flat top cover should be selected, and a diversion ring should be set under it. The angle between the water collector and the airflow section should be controlled within 90-120 degrees. between.

2. For the shortened tower top, the top angle of the shortened section cover plate should be controlled between 90-110 degrees.

3. The inclination angle of the water filler is controlled between 5-8 degrees.

4. In the process of use, in order to prevent the short circuit between the air and the bottom of the filler to the water surface, spare circulation measures should be set up.

3. How to choose the cooling tower packing:

1. The selection of cooling tower packing varieties should consider the requirements of the separation process, usually considering the following aspects:

(1) The mass transfer power is higher. Generally speaking, the mass transfer power of structured packing is higher than that of bulk packing. 

(2) The flux should be large. Under the premise of ensuring high mass transfer power, fillers with high flooding point gas velocity or gas phase kinetic energy factor should be selected.

(3) The pressure drop of the packing layer should be low.

(4) The packing has strong anti-fouling and blocking function, and is convenient for disassembly, assembly and maintenance.

2. Selection of fillers:

The temperature drop is large, the airflow resistance is small, the price is cheap, and the hydrophilicity is good, which can make the water flow slowly down, easy to form a film, have abundant heat exchange time, and high heat dissipation power.

As the main center of circulating water heat dissipation in industrial production, cooling towers affect the cost and power of industrial production in my country. Improper use of cooling towers in industrial production will result in untimely cooling of equipment, stagnant production, and dangerously high water temperature. The cooling tower packing is the primary factor to promote the water and heat cycle, therefore, it is necessary to choose high-quality cooling tower packing.

1. Specifications for cross-flow cooling towers

The spacing between the top of the cooling tower fill and the lower end of the fan should be 1.2 times the diameter of the fan.

2. Specification Angle of Counterflow Cooling Tower

1. When building a counter-flow cooling tower, the angle between the top of the packing and the airflow section should be controlled within 90 degrees, a flat top cover is used, and a diversion ring is set below, and the angle between the water collector and the airflow section should be controlled within 90-120 degrees. between.

2. For the shortened tower top, the top angle of the shortened section cover plate should be controlled between 90-110 degrees.

3. The inclination angle of the water filler is controlled between 5-8 degrees.

4. In the process of use, in order to prevent the short circuit between the air and the bottom of the filler to the water surface, spare circulation measures should be set up.

2. Selection of fillers:

The temperature drop is large, the airflow resistance is small, the price is cheap, and the hydrophilicity is good, which can make the water flow slowly down, easy to form a film, have sufficient heat exchange time, and high heat dissipation power.

3. The filler is the key part of the heat exchange of the cooling tower. The air and water heat exchange process in the tower is mainly completed in the water filling, so

The thermal and resistance characteristics of the water spray filler are the primary factors affecting the cooling effect of the cooling tower.

The quality of the filler material will affect the use of the cooling tower. The filler is the central part of the cooling tower, and it plays an irreplaceable role in its operation. The cooling tower filler surface is aging due to the wind and the sun.

Deformation, the density of the whole packing is loose, so that the cooling water can not make full use of the packing to dissipate heat. The heat exchange is blocked, so that the cooling tower cooling cannot achieve a stable effect.

4. The filler is the central heat exchange part of the cooling tower, which is directly related to the cooling performance. The quality and design of the filler directly affect the cooling capacity of the cooling tower to a large extent. According to the material, in the heat exchange ratio of the entire cooling tower, the filler occupies 60% to 70%.

5. The filler is generally made of uneven PVC or PP material, and the hydrophilic function is better. It must also ensure that the cooling water forms a water film and water droplets on the filler, rather than water flow. Such a cooling tower filler can enhance the water well. The air exchange area extends the exchange time of air and water to ensure the cooling effect. So, what about the high temperature resistant cooling tower fill?
