Jingchuang environmentally-friendly independently developed sludge low-temperature drying equipment is based on the principle of low-temperature evaporation, condensation, and dehumidification of heat pumps. It uses hot air convection drying to perform low-temperature evaporation and dehydration of wet sludge on the mesh belt, and circulates condensed humid air to make The sludge is dried.

The sludge low-temperature drying equipment developed by Jingchuang Innovation can directly dry sewage or sludge with a moisture content of 83% to 10% -30% dry sludge with a water content reduction of up to 90%.
90%, low energy consumption, no pollution, widely used in municipal sludge and industrial sludge (printing and dyeing, papermaking, electroplating, chemical, leather, pharmaceutical, etc.)
In the future, it can be disposed of harmless resources such as gasification, blending, composting or building materials.

Adopting the low-temperature dehydration and drying sludge room solution, the screw pump transports the settled sludge with a water content of more than 98% to the continuous dehydration unit, and the sludge dewatered to 78% -83% falls into the low-temperature belt dryer by its own weight. After the molding, the cloth is distributed on the mesh belt of the sludge conveyor. The humid and hot gas generated by the evaporation is circulated into the heat pump for dehumidification and dehydration. At the same time, the heat is recovered and the recirculated gas is reheated. , Drying temperature 40 ℃ -80 ℃. The generated dehumidification condensate can be discharged directly.

Three different types of sludge were produced in the production process of a chemical company in Jiangsu and Zhejiang, and were treated with three different dewatering equipments. The final average moisture content of the dehydrated sludge was about 70%, and the heat pump low temperature drying technology was used to treat them separately, and finally achieved stability. Disposal in different directions of harmlessness and resource recovery achieves the goal of harmlessness, while generating additional benefits.

The composition of pharmaceutical sludge is complex, and the composition and characteristics of the sludge components of different pharmaceutical plants vary greatly, but their common feature is the difficulty of processing. The reason is that the sludge contains a variety of organic matter, heavy metals, antibiotics, etc., conventional physicochemical + biochemical treatment is difficult to effectively remove toxic and harmful substances, and some of the components in the sludge will also have inhibitory effects on the process effect.

Electroplating wastewater treatment system, using plate and frame filter press for dehydration, daily output of 1 to 2 tons of wet mud containing heavy metals, stable output of 1.5 tons, mud cake moisture content of about 70%, according to common sense, wet mud reaches this index It is already very good, but there is still a problem, what's the matter?
