Abstract

The invention provides a sludge drying structure which comprises a drying area and a heating area, hot air output by the heating area enters the drying area, and air in the drying area flows into theheating area through an air passing plate; and an included angle is formed between the gas outflow direction of the drying area and an air passing bent part of the air passing plate. According to thedesign position and the design angle of the air passing plate, the problem that circulating gas generates vortexes is fully considered, and vortexes generated in the gas circulation process are reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the field of sludge drying, and in particular relates to a sludge drying structure. Background technique [0002] The necessary process in sewage treatment is sludge drying and dehydration, and the most environmentally friendly technology among the common sludge drying and dehydration methods is low-temperature sludge drying technology, which uses electric energy to directly heat gas to dry sludge , but the biggest problem in this technology is that there is a lot of waste heat and the recycling rate is relatively low. Moreover, in the improved two-stage drying structure technology on the market, using waste heat technology to carry out circulation drying will inevitably generate vortices during gas circulation, causing problems in gas circulation efficiency, and at the same time, the limitations of internal structure design cause uneven gas circulation , poor degree of drying and so on. Contents of the invention [0003] I...
