Description

A cationic resin separation and recovery system

technical field

The utility model relates to a cationic resin separation and recovery system.

Background technique

At present, fixed-bed cationic resin reactors are widely used in industrial production, and are mainly used to recover precious ions or toxic and harmful ions (referred to as target ions) in industrial tailings (liquid) through ion exchange. The resin absorbs the high-concentration target ions in the material, replaces it with other materials, and then uses the regeneration liquid to perform desorption and resin regeneration, so as to achieve the purpose of recycling. Compared with other resin reactors, fixed beds have the advantages of simple operation, low investment and maintenance costs, which is why many industries and manufacturers choose fixed beds. After the resin in the fixed bed has been running for a long time, part of the resin is worn and crushed, which affects the overall performance of the resin. The usual treatment method is to discharge all the resin in the reactor and put in new resin. Because the used resin cannot be separated into good and bad, resulting in the waste of partially intact resin, and at the same time, it is necessary to stop the device regularly for batch replacement, which requires a large amount of manual labor.

Utility model content

The technical problem to be solved by the utility model is to provide a cationic resin separation and recovery system that can save resin and reduce labor intensity.

The utility model adopts the following technical solutions:

After the resin reacts in the resin reactor for a period of time, part of the resin is discharged into the water washing tower 1. After the resin passes through the water washing tower, the broken resin floats in the water under the action of water in the water washing tower. The surface of the water flows out through the overflow port offered on the water washing tower 1, and the good resin sinks to the bottom of the water washing tower 1 under the action of gravity, and the feed inlet of the delivery pressurized tank 2 passes through the pipeline and the The discharge port at the bottom of the water washing tower 1 is connected, and the good resin is directly discharged into the conveying pressurized tank 2 and then pressurized to reach the resin adding head tank 3.
