Description

Technical Field

[0001] The utility model belongs to the technical field of resin separation, and particularly relates to a resin separation tower by the high tower method. Background Technique

[0002] In water treatment, it is often necessary to output the mixed bed resin to a resin separation tower to clean and completely separate the anion and cation resins. At present, the hydraulic screening method is used to scrub and layer the anion and cation resins. It uses the hydraulic force of the backwash water to suspend the resin, making the resin layer reach a certain expansion height and maintaining it for a period of time, and then stops the backwash, and the resin settles by gravity.

[0003] In the existing one, there are a resin inlet, a cation outlet and an anion outlet on the resin separation tower. The cation outlet is located above the anion outlet, and there is a water inlet at the top of the resin separation tower and a drain outlet on the side wall of the lower part. When flushing the resin by injecting water, when the resin and the water flow are injected into the separation tower, and the resin and the water flow fall from the top of the separation tower onto the surface of the perforated plate for resin separation, the mixed liquid of the resin and water falling onto the surface of the perforated plate is likely to accumulate on the surface of the perforated plate and cannot be evenly distributed, resulting in the situation that the local water flow is too large or too small, making the flow state of the resin in the separation tower unstable, affecting the sedimentation and layering effect of the resin, and reducing the separation accuracy and efficiency.
