Sludge drying processing device and technology thereof

Abstract

The invention discloses a sludge drying processing device and a technology thereof. The device comprises a sludge feeding unit, a paddle sludge drying machine, a condenser, an induced draught fan, a heating boiler, and a gas turbine, wherein the sludge feeding unit is connected with the paddle sludge drying machine, the water outlet of the paddle sludge drying machine is connected with the heating boiler, the gas outlet of the paddle sludge drying machine is connected with the condenser, the gas outlet of the condenser is connected with the induced draught fan, the induced draught fan is connected with the heating boiler, the gas outlet of the heating boiler is connected with the gas turbine, the gas turbine is connected with the gas inlet of the paddle sludge drying machine, the sludge outlet of the paddle sludge drying machine is connected with the bottom sludge inlet of the heating boiler. According to the invention, the volume and weight of the sludge can be greatly reduced, partial heat energy and waste residues can be recycled, thus the invention is significant in protecting the environment, promoting the sustainable developments of nation economy and ecological environment, has important social meaning, and is in compliance with the national industrial policy.

Description

Technical field [0001] The invention involves a sludge dry treatment device and its process. Background technique [0002] With the development of my country's socio -economic and cities, the production of urban sewage has continued to increase.In recent years, the state has actively supported the policy and financial resources, and has built a large number of urban sewage treatment plants to maintain water environment, prevent water pollution, and promote the sustainable development of the national economy and ecological environment. The problem of urban sewage has been gradually eased.However, the treatment of urban sewage sludge is still a worldwide technical problem. Improper disposal will cause severe secondary pollution and the harmless treatment of sludge. [0003] At present, the method of sewage treatment plants usually uses sludge dehydration and exterior landfill treatment. This treatment method not only causes pollution to the environment and occupies a large amount o...

AI Technical Summary

Problems solved by technology

However, the treatment of urban sewage sludge is still a worldwide technical problem. Improper disposal will cause serious secondary pollution, and the problem of harmless treatment of sludge is becoming increasingly serious.

[0003] At present, the method usually adopted by sewage treatment plants is to dehydrate the sludge and transport it to landfill. This treatment method not only pollutes the environment but also takes up a lot of land.
