Advantages of drying structure of electroplating sludge dryer

Electroplating sludge is mainly the precipitate which is produced in the process of treating electroplating wastewater, which is mainly composed of heavy metal hydride such as copper and chromium. Because of its high water content and complex composition, if it is discharged directly without treatment, it will cause serious pollution to the environment. The electroplating sludge dryer can effectively realize harmless, stable and reduced treatment of sludge. At the same time, the sludge after drying can realize the possibility of metal recycling and reuse, which can reduce the pollution to the environment and realize the secondary reuse of resources. Therefore, more and more users like to use drying equipment to treat sludge.

Drying structure of electroplating sludge dryer:

The electroplating sludge dryer adopts three drum structure, which is embedded by three cylinder sleeves with different diameter. This structure not only increases the internal volume, but also reduces the length of the cylinder, makes the drying process of the equipment become "w+s", and extends the travel and retention time of sludge in the inner cylinder. At the same time, the structure is sealed tightly, and the three-layer nesting technology makes the equipment heat preservation effect very good, improves the thermal energy utilization rate inside the equipment, reduces the heat loss of the cylinder, and reduces the production cost. Reduce the overflow of flue gas dust inside the cylinder, and ensure the clean and tidy production environment of the equipment.

In addition, special dispersal device and lifting material device are installed on the wall of the cylinder. It can continuously disperse, separate and stir the sludge, promote the sludge forward, accelerate the mixing contact between sludge and hot air, avoid sludge sticking and agglomerating, improve the production efficiency of the equipment, and ensure the quality of sludge after drying.

Advantages of electroplating sludge dryer

1. The structure of this equipment greatly reduces the floor area, and can be reasonably assembled according to the actual land area.

2. The processing capacity is strong, the production efficiency is high and the production cost is low.

3. The integrated control is simple and convenient, the equipment performance is stable, the failure rate is low and the maintenance cost is low.

4. The equipment is also equipped with professional dust removal equipment, which can send the flue gas dust generated in the production process to the dust removal equipment through the induced draft fan for filtration, purification and dust reduction, so as to meet the requirements of gas emission. Zero pollution and zero emission can be realized to reduce the impact on the environment.

5. The moisture content and particle shape of the sludge after drying can be adjusted according to the requirements of the user, so as to facilitate the subsequent reuse of sludge.
