Ceramic pall ring is a new type of filler. It is improved for some major shortcomings of Lasci Ring. It is an eight -layer rectangular window on the wall of the ordinary Laxi ring. The positions of the upper and lower layers are intertwined. The main difference between it and the Lacey Ring filling is that there is a rectangular window hole on the side wall, and the window leaves of the window holes are bent into the ring heart. Because the opening of the ring wall makes the distribution of gas and liquid In the improvement, the inner surface area of the ring can be fully utilized.
The ceramic pall ring has the advantages of large flux, low resistance, high separation efficiency, and large operating elasticity. Under the same lower voltage, the processing volume can be more than 50%larger than the Lasi ring. When the same processing volume, the lower voltage can be reduced by half, and the mass transmission efficiency can increase 20%. Under normal circumstances, the treatment may be 50%-99%larger than the Lasi ring, and the pressure drop is 50%-70%smaller than the Lasi ring during the treatment. The section of about 20%-40%of the filler volume.
Advantage of Pall Ring
The air pre -cold system often uses the pall ring as a filler. The free stacking method is used. When the quality and heat transfer are performed, the liquid is evenly inferred from the top of the tower. In contact with the liquid film, conduct hot exchange. Make full use of the inner surface of the ring. Compared with the Lasi ring, the processing volume of the pall ring can be more than 50%larger, and the pressure is reduced by half.
Practice has proved that the air -cooled system uses the ceramic pall ring filler tower and compared with the sieve pagoda. On the one hand, it has strong heat transfer capacity. The temperature difference between the air temperature of the cold tower and the temperature difference between the cold water in the upper section can be less than 1 ° C. The water outlet temperature of the water -cooling tower can produce a negative temperature difference between 4 ~ 5 ° C between the tower’s nitrogen temperature; due to the accumulation gap rate of 94 ~ 95%, so it is not easy to block, and it is not easy to choose foaming bands, which is conducive to changing working conditions. After the air volume is increased, it is not easy to bring water.
In addition, it also shows the characteristics of small pressure drops. The resistance of the filler per meter is about 10mm of water columns; the water consumption of the air -cooled tower can be reduced by 30%; it can reduce the refrigeration of the cold water machine. It can not be turned on in winter, and the cooling capacity of summer can be reduced by 80%, which is possible to achieve air -free air pre -cooling systems; in addition, it is also convenient for installation and low manufacturing costs.
The water -cooled tower can choose a common type of polycopylb -dilute pall ring. When the air -cooled tower is started, if the air compressor is not set up, the air temperature at the time of start is about 90 ° C. Most of the choice of ordinary polycoprobalism pall ring fille. At the bottom of the filler, the stainless steel pall rings should be selected at about 2m high to prevent the compressive compressive strength of the compressive deformation.
