Abstract

The invention discloses a novel air medium type sludge drying system which comprises a sludge drying machine, the bottom end of the sludge drying machine is connected with an air outlet duct, the air outlet duct is connected with an inlet of a cyclone dust collector, the top end of the cyclone dust collector is connected with a circulating air return duct, and the bottom end of the cyclone dust collector is connected with an ash discharge port. The circulating air return duct is connected with the inlet of a circulating fan. The sludge drying system is scientific and reasonable in structure and safe and convenient to use, a closed hot air circulation sludge drying system is adopted, a hot air heating system with electricity or steam as a heat source is high in operation energy consumption, a system with a heat pump as a hot air heating device is complex in structure, a waste gas condensation system generates a large amount of condensed waste water, and the treatment cost is high; in addition, components and flow of the hot air can be changed after the hot air is recycled for a long time, and finally safety of system equipment and stability of a system are affected.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel wind-driven sludge drying system. Background technique [0002] Sludge is the product of sewage treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main feature of sludge is high water content (up to 99% or more) ), high organic content, easy to rot and smell, and fine particles, small specific gravity, colloidal liquid, it is a thick substance between liquid and solid, it can be transported by pump, but it is difficult to pass through sedimentation Carry out solid-liquid separation; [0003] However, the sludge drying system currently on the market is not only complex in structure, but also has a single function, complex operation, poor stability, low safety, and is greatly affected by the external environment. Contents of the invention [0004] The present inve...
