A kind of sludge treatment equipment adopting catalytic wet oxidation method

Abstract

The invention relates to a sludge treatment equipment adopting catalytic wet oxidation method, relates to the technical field of sludge treatment equipment, including a flushing high-temperature autoclave and a sealing cover, an electric furnace is arranged on the left side of the front of the high-temperature autoclave, and An oxygen tank is externally connected to the left, and the sealing cover is placed on the upper end of the high-temperature autoclave, and the sealing cover and the high-temperature autoclave are connected by bolts, and an air inlet pipe is inlaid on the upper right side of the oxygen tank. The beneficial effects of the present invention are: the stirring rod can be driven to stir the sludge by using the rotating shaft to rotate in the high-temperature autoclave, so that the catalyst and the sludge can be mixed quickly and uniformly, and the sludge can be fully and quickly contacted with oxygen. It can speed up the catalytic oxidation of sludge, and at the same time make the sludge contact with heat, so that the sludge can be processed quickly, and the organic matter and reducing inorganic matter in the sludge can be quickly oxidized into carbon dioxide, water and a small amount of solid residue.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to sludge treatment equipment using a catalytic wet oxidation method. Background technique [0002] The sludge in urban sewage treatment plants mainly comes from primary sedimentation tank sludge and residual activated sludge. There are many ways to dispose of urban sludge, which vary greatly depending on the situation of the country. According to the final destination of the sludge, it can be divided into sludge Utilization and harmless of sludge, wet air oxidation technology is to fill oxygen under high temperature and high pressure to oxidize organic matter and reducing inorganic matter in sludge into carbon dioxide, water and a small amount of solid residue. This method can obtain high The organic matter removal rate and energy recovery rate are high, and the treatment is carried out in a closed container without odor and soot. The sterilization effect is good...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of sludge treatment equipment adopting catalytic wet oxidation method to solve the problem of the high-efficiency and safe sludge environmental protection treatment equipment disclosed in the Chinese invention patent application publication specification CN107804956 A proposed in the above-mentioned background technology. Although the sludge environmental protection treatment equipment is driven by the motor to accelerate the evaporation of the moisture in the sludge, and the fan accelerates the air flow to accelerate the evaporation, but the moisture generated in the sludge cannot be used for secondary use, and although the generated gas is collected by the gas collecting tank , to prevent it from being discharged into the air to affect the environment, but the gas generated after being heated by the heater has a certain temperature, and direct collection will cause the problem of heat loss
