Sludge treatment device using catalytic wet oxidation method

Abstract

The invention relates to a sludge treatment device using a catalytic wet oxidation method, and relates to the technical field of sludge treatment equipment, the device comprises a high-temperature high-pressurekettle and a sealing cover, the left side of the front surface of the high-temperature high-pressure kettle is provided with an electrothermal furnace, and the left side of the high-temperature high-pressure kettle is connected with an oxygen gas tank, the sealing cover is arranged at the upper end of the high-temperature high-pressure kettle, and the sealing cover is connected to the high-temperature high-pressure kettle through bolts, and the upper right side of the oxygen gas tank is inlaid with an air inlet pipe. The method has the advantages that: by rotating an agitator shaft in the high-temperature high-pressure kettle through a rotating shaft, aagitator rod can be driven to stir the sludge, so that the catalyst can be mixed with the sludge quickly and evenly, and the sludge can be fully and rapidly contacted with the oxygen. The catalytic oxidation of the sludge can be accelerated and the sludge is uniformly contacted with heat, so that the sludge can be quickly treated, and the organic matters and reductive inorganic matters in the sludge can be quickly oxidized to carbon dioxide and 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...
