A sludge drying treatment device

Abstract

The invention discloses a sludge drying treatment device which comprises a sludge conveyor, a first drying chamber, a second drying chamber, a third drying chamber, a cooling chamber, a dry sludge storage bin, a washing dust removal chamber, a biological deodorization chamber and a control chamber. The first drying chamber, the second drying chamber and the third drying chamber are arranged to dry sludge through industrial waste gas, solar energy and a heating device, the drying efficiency is high, the drying cost is low, energy is saved, and fuel coal consumption is low. The washing dust removal chamber and the biological deodorization chamber are arranged to carry out dust removal and deodorization on tail gas, the concentration of odors discharged into the external environment is reduced, and it is avoided that baneful influence is caused to the environment. A sterilization liquid injection device is arranged in the first drying chamber, and sludge stored for a long time can be sterilized. Ultraviolet lamps are arranged in the three drying chambers respectively, so that a sterilization function is achieved while drying is achieved, and it is restrained that the sludge continues to generate odors.

Description

Technical field: [0001] The invention belongs to the technical field of sludge drying equipment, and in particular relates to a sludge drying treatment device. Background technique: [0002] At present, sludge disposal in large cities has become difficult and expensive, long-distance sludge haulage, fuel and transportation costs have increased, sludge landfills consume a lot of land resources, and costs have increased, wet sludge direct incineration is expensive, and because Due to problems such as smog, citizens opposed the construction of incinerators in the city. Thermal drying of sludge is a safe, reliable, fast, efficient and large-scale sludge reduction technology. Sludge drying refers to the process of removing most of the water content from sludge through percolation or evaporation. After the sludge is thermally dried, the following effects can be achieved: the sludge is dried from 25% DS to 90% DS, the weight is reduced by about 78%, the product is easy to post-pro...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that the drying efficiency of the sludge drying treatment equipment in the prior art is low, the coal consumption is large, the drying cost is high, and the tail gas has a bad impact on the environment, so a sludge drying equipment is proposed.
