Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem existing in the prior art that the contact area between sludge and air is small in the process of sludge drying, thereby affecting the evaporation efficiency of water, and to provide a sludge drying device. The device can increase the contact area between the sludge and the air, and allow the sludge to have ample time to dry, which greatly improves the drying effect and drying rate of the sludge

Abstract

Relating to the field of waste disposal, the invention discloses a sludge drying device and a sludge drying method. The sludge drying device comprises a drive mechanism (10), which comprises a plurality of support rollers (12), each of which can rotate around the central axis of the same, and the sludge drying device also includes a conveyor belt (20), at least one side of the conveyor belt can becoated with sludge, and the conveyor belt is wound around the plurality of support rollers and form a closed conveying path. The sludge drying device can increase the contact area of sludge and air,and endows sludge with sufficient drying time, thus greatly improving the sludge drying effect and drying rate. The sludge drying method provided by the invention increases the contact area of the sludge layer and air, also endows the sludge layer with sufficient drying time, thereby greatly improving the sludge drying effect and drying rate.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to a sludge drying device and a sludge drying method. Background technique [0002] Sludge drying refers to the process of removing most of the water content from sludge through percolation or evaporation. It generally refers to the use of self-evaporating facilities such as sludge drying plants (beds) to dry sludge. Sludge drying has been widely used in sewage treatment. Sludge, as an accompanying organism in the sewage treatment process, will cause various environmental problems if it is not treated. [0003] Sludge drying generally needs to go through the following three processes: (1) radiation drying, when the sludge at room temperature receives the radiation of the heat source, the temperature rises, and the moisture inside the sludge continuously diffuses to the surrounding air, which will Increase the air humidity on the surface of the sludge, and the air humidity on the surf...
