Sludge Drying Equipment/Shandong Electroplating Sludge Drying Equipment Case

Case introduction of sludge drying equipment/Ling County electroplating sludge drying equipment project:

The speed of sludge drying equipment is affected by factors such as temperature, wind speed, contact area with hot air, and motion state. Heat pump drying technology is a drying technique that reduces the drying temperature and increases the wind speed. The advantage of this technology is that it does not have the problem of producing a large amount of exhaust gas during high-temperature drying, nor does it affect the appearance of the finished product due to too fast drying rate. Moreover, due to the low temperature, the cost of heating will be greatly reduced. At present, the application of heat pump low-temperature drying technology is becoming increasingly widespread, which can be applied to the drying of sludge such as sewage treatment, papermaking sludge, leather sludge, textile sludge, electroplating sludge, printing and dyeing sludge, chemical sludge, coal slurry, etc. It provides solutions and technical support for sludge disposal, metal recovery, and solid waste disposal enterprises.

Sludge drying equipment:Metal sludge comes from electroplating, chemical sludge, etc. The solid waste generated from the sludge of electroplating plants has a complex composition of metal sludge due to different production processes of various electroplating plants, such as containing various heavy metals such as chromium, iron, copper, zinc, etc. The volume and mass are relatively large, with low organic content and low calorific value; The composition of chemical sludge is relatively complex, with a high viscosity and a water content of over 80%. After passing through the dewatering machine, the water content still remains at 70%~85%. Sludge containing different types of heavy metals generally has different ratios of heavy metals. By using heat pump sludge drying equipment, the disposal cost of sludge can be greatly reduced, which is an important way to achieve sludge volume reduction, weight reduction, harmless disposal, and recovery of valuable metals.
