Product Overview:

The specialized chemical sludge dryer is capable of drying chemical sludge with low energy consumption and operating costs, achieving automation in chemical sludge treatment. The drying speed is fast, with a daily processing capacity of 200-2000 tons of chemical sludge. It adopts a multi-layer three-dimensional design with good drying effect, which can dry chemical sludge with a moisture content of about 80% into particles with a moisture content of less than 35%.

Chemical sludge dryer features:

Low energy consumption of chemical sludge dryer: Due to indirect heating, it does not carry a large amount of air to take away heat. The outer wall of the dryer is also equipped with insulation layer. For slurry materials, only 1.22kg of water vapor is needed to evaporate 1kg of water.

The blade dryer system has low cost: it has a huge heat transfer surface per unit effective volume, which shortens processing time and reduces equipment size. This greatly reduces the building area and space.

Wide range of material processing: Using different heat media, it can handle both thermosensitive materials and materials that require high-temperature treatment. Common media include steam, thermal oil, hot water, cooling water, etc. It can operate continuously or intermittently and can be applied in many fields.

Low environmental pollution: No use of portable air, minimal dust and material entrainment. The solvent evaporation of the material is very small, making it easy to handle. For materials that are contaminated or require solvent recovery, closed-loop circulation can be used.

Low operating costs: The device operates normally with only 1-2 people per day. Low speed stirring and reasonable structure. The wear and tear is small, and the maintenance cost is very low.

Stable operation: Due to the special compression expansion stirring effect of the wedge-shaped blade, the material particles are fully in contact with the heat transfer surface. In the axial range, the temperature, humidity, and mixing gradient of the material are very small, thereby ensuring the stability of the process.

Drying value of chemical sludge:

After drying, chemical sludge can be made into environmentally friendly bricks and used as fuel for power generation, achieving harmless, reduced, stable, and resourceful treatment of chemical sludge

Characteristics of chemical sludge:

The amount of sludge generated during the treatment of chemical wastewater is relatively large, with an average sludge content of 6 to 7 tons per 10000 tons of chemical wastewater, which is several times higher than the sludge content of ordinary wastewater. It has become an important factor in the pollution control process of the chemical industry and contains a large amount of toxic and harmful substances to the human body, such as heavy metals, pigments, hazardous pollutants, pathogens, etc.
