Abstract

The invention belongs to the field of sludge treatment and recycling of municipal sewage treatment plants, and particularly relates to a sludge micro-positive pressure carbonization control system and a gas purification method. The sludge micro-positive pressure carbonization control system comprises a sludge carbonization furnace, a finished product material sealing bin, a decoking cooler, a tar collector, an immersion type pressure control cleaner and a leaching tower. Immersive water pressure control is adopted, a carbonization system is controlled in a micro-positive pressure environment, and a carbonization environment is kept in a sludge carbonization pyrolysis gas environment, so that air is prevented from entering; the sludge is in a pyrolysis gas atmosphere (hydrogen, methane, carbon dioxide, carbon monoxide and nitrogen are greater than or equal to 80%), so that the mineralization degree of the sludge caused by air oxidation is effectively reduced.

Description

technical field [0001] The invention belongs to the field of sludge treatment and resource utilization in urban sewage treatment plants, and more specifically relates to a sludge micro positive pressure carbonization control system and a gas purification method. Background technique [0002] In recent years, the level of urbanization in my country has been greatly improved, the level of centralized sewage collection and disposal is getting higher and higher, and the generation of urban sludge is increasing rapidly. With the rapid development of the economy, the amount of sludge generation and treatment level will be greatly improved. degree of improvement. [0003] Urban sludge contains a large amount of organic matter, nitrogen, phosphorus and other nutrients. The content of organic matter accounts for more than 50%, which contains a large number of bacteria, fungi and other microorganisms. If it is not handled properly, it will cause great harm to the environment. [0004]...
