Description

TECHNICAL FIELD

[0001] The application relates to the technical field of solid waste drying, in particular to an energy-saving organic solid waste drying device. BACKGROUND

[0002] In the field of environmental protection and solid waste management, effective treatment of solid waste is crucial. Solid waste reduction, as a common and effective treatment method, is of great significance in reducing the amount and volume of solid waste from the source and minimizing the types of solid waste.

[0003] The utility model patent with the application number 202020198546.3 is a system for closed drying of sludge using flue gas or steam waste heat. The lower part of the sludge stirring shaper is provided with a drying box, and the inside of the drying box is provided with an S-shaped sludge conveying belt, a bottom shell-free fan, and an upper circulating fan. The dehumidification system includes a plate-type dust removal device, a heat exchanger, a heating group, a condensing group, and an upper circulating fan. The wet and hot air in the drying box is sucked into the drying system by the upper circulating fan and is divided into two paths. One path returns to the drying box, and the other path passes through dust removal, heat exchange, condensation, and water separation before being heated into high-temperature dry gas and then entering the drying box to realize air circulation. The utility model uses flue gas waste heat or steam waste heat as a heat source to dry the sludge. The dried sludge can be used for power generation, heating, or as auxiliary materials for construction, achieving energy recycling.

[0004] The patent provides a technical solution for drying sludge, which also has similar applications in the field of organic solid waste drying. However, due to the excessive water content of organic solid waste, it is easy to stack and present different thickness shapes after falling from the stirring shaper due to gravity. In this case, heat is difficult to evenly distribute to each part, which can easily lead to over-drying in some areas while other areas are still not completely dry, greatly affecting the drying effect.
