JINLING DRYING

The main body of the belt type sludge drying system consists of multiple unit structures. Dehydrated sludge is sent to the extruder through the feeding system and evenly laid on the drying belt, which sends the sludge into the main structure of the device; In the drying chamber, heating gas raises the temperature of the drying chamber to the set value, and hot air enters the drying device from the upper or lower part of the device, flowing through the entire drying zone. When air flows through the sludge laid on the drying belt, it takes away the moisture in the sludge, achieving the drying of the sludge.

The low-temperature drying unit is a professional equipment that utilizes the Carnot cycle principle and is equipped with a combination of air supply system, heat exchange system, etc. It is a new type of high-efficiency and energy-saving drying unit. According to the Carnot cycle principle, a small amount of electrical energy is consumed to drive the compressor to compress the medium into high-temperature and high-pressure gas, which enters the condenser to release heat. The heat released by the condenser is sent to the drying chamber by the circulating fan, which heats up the materials in the drying chamber and repeatedly circulates to absorb moisture from the materials. The moisture is continuously vaporized and removed from the surface of the materials, and then cooled and dehumidified by the evaporator to discharge the moisture in the materials, achieving material drying.

Waste heat air or heat exchange air enters the rotary dryer and directly exchanges heat and mass with wet sludge in the channel. It is equipped with a special crushing device (specially designed structure) to quickly evaporate the water in the sludge. The smaller sludge particles are discharged from the dryer and collected together with the gas through the outer channel, while the larger sludge particles stay in the dryer for a longer time until drying is completed. Part of the exhaust gas is extracted and treated by a deodorizer to meet atmospheric emission standards (or cooled by water foam dust removal) before being discharged into the atmosphere.
