In the ion exchanger, the counter-current regeneration technology has been widely used, while the counter-current regeneration technology, the key device is a switch inside the middle of the drainage device (referred to in the row). For a long time, this device is commonly used master pipe branch pipe, in the branch pipe openings, and puts on PVC and polyester nets, and then re-use stainless steel wire or polyester rope truss. long-term use is proved that this structure has a great overhaul workload. There are already more and more The water treatment equipment factory in the middle of the stainless steel sieve with the drainage, in order to increase the rigidity of sieve tubes, generally in the sieve tubes of the inside lining of stainless steel porous tubes.

  V-around stainless steel wire in handling devices, and can replace stainless steel pipe openings re-package polyester nets old-fashioned branch pipes, circulation area, water distribution uniformity, mechanical strength, temperature resistance, pressure nature of anti-aging, anti-corrosive have been greatly enhanced. Stainless steel wire around the space can be designed according to the size of the resin. The products are ranked fishbone-type devices and hanging type medium-handling devices.
