What is used as packing in chlorine scrubbers?

This post was last edited by sunjl1981 on 2013-1-6 at 23:57. What kind of packing do you use in the chlorine scrubber towers? Some say PVC is used; are there any other types of packing? What is the diameter of that packing, and what is the amount used? How is it added? Is the filler the same in sulfuric acid drying as in the scrubber tower? # ， ， &
The packing for chlorine scrubber towers can be made of PVC or CPVC. The filler form can be stepped rings or wreaths. The typical diameter is 50–80. A filler layer height of 4 meters is sufficient. The dosage can be determined based on the diameter of the scrubber tower corresponding to the chlorine flux. Considering the temperature resistance requirement, CPVC can be used as the filler in the sulfuric acid drying tower.
Both PVC and CPVC possess resistance to chlorine corrosion, but PVC has poor heat resistance – it deforms at temperatures above 60 degrees, while CPVC can withstand temperatures above 90 degrees; according to the material specifications, it can even tolerate temperatures up to 110 degrees. Relatively speaking, the price of CPVC is much higher.
Our company uses CPVC Taylor wreaths.
CPVC has better resistance to chlorine corrosion compared to PVC; it can withstand high temperatures of over 90 degrees, with the material’s specifications indicating that it can tolerate temperatures up to 110 degrees. Relatively speaking, the price of CPVC is much higher. By using wreaths, we can increase the contact area and contact time, resulting in a better drying effect.
As the friend mentioned above, CPVC can be used; for Taylor wreaths, PVC has poor heat resistance and tends to degrade and become fragile. In the tower, materials are piled up in a disordered manner. Behind the chlorine scrubber tower, towers that use a combination of structured packing and bubble trays can also be utilized. When selecting a filler, factors such as the medium, temperature, specific surface area, and filler material must be taken into account.
A CPVC wreath can be used as the filler
The temperature in the chlorine water washing tower is high, so PVC cannot be used; our factory uses CPVC rings. It seems that this needs to be designed by a specialist
Use CPVC wreaths; PVC wreaths should not be used. Those imported are of better quality and less likely to break, while domestic ones are cheaper but more fragile, and they can easily get into pumps or heat exchangers, even causing blockages in the pipes
Our company uses CPVC duckbill rings
Both PVC and CPVC are resistant to moist chlorine gas, but given that the operating temperature in the scrubber tower is between 45 and 80 degrees, CPVC packing is chosen; short stepped rings or floral rings can both be used.
