Abstract

The invention relates to the technical field of solid waste treatment, and discloses a thermal energy utilization integrated device, a material drying system and a drying method. The casing of the present invention is divided into three independent chambers arranged horizontally and side by side by the sealing plate. The chamber is respectively equipped with a exhaust steam recovery module, a heat energy conversion module and a hot air heat absorption module. The circulating medium passes through the heat energy conversion module. The exhaust steam recovery module and the hot air heat absorption module circulate independently. The invention has high cycle thermal efficiency, low energy consumption and good system operation stability.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a thermal energy utilization integrated device, a material drying system and a drying method. Background technique [0002] Material drying is an important link and key technology in chemical production during food processing, solid waste disposal, and mine slurry disposal. In order to meet the wastewater discharge requirements, the high-temperature wastewater generated in the production process of industry and processing manufacturing needs to be cooled, which not only wastes a lot of water resources, but also wastes a lot of heat energy. [0003] At present, the disposal methods of sludge and solid waste are often coupled with large-scale coal-fired boilers. The process routes mainly include direct blending and drying blending, and drying blending is based on steam drying and hot air drying. Mainstream technology. [0004] The traditional steam disc sludge dryin...
