Description

Technical Field

[0001] The utility model relates to the field of deodorizing devices, in particular to a sludge disposal deodorizing device. Background Art

[0002] Sludge disposal is the process of reducing, stabilizing and harmlessly treating sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Unless land treatment or sewage pond treatment is used, general sewage treatment plants must have sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal has become the most complex and costly part of sewage treatment system operation. Sludge disposal will produce odor and cause environmental pollution. Therefore, a sludge disposal deodorization device is particularly needed.

[0003] According to the published patent 202321588508.9, a sludge disposal and deodorization device comprises a deodorization tank, a stirring mechanism is arranged inside the deodorization tank, the other end of the first water pipe is connected to a mixing barrel, a feed port is installed on one side of the surface of the mixing barrel, a spray mechanism is arranged inside the baffle cover, and a filtering mechanism is arranged on one side of the surface of the baffle cover. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved, which are solved by setting an exhaust pipe, a support block, a movable groove, a reset spring, a limit block, a steel cable, a pull ring, a filter frame and a filter net during use. In the process, most deodorization devices only deodorize the sludge by adding deodorizers to the sludge. This method has limited effect on sludge deodorization. At the same time, if the residual odor of the sludge is directly discharged into the air, it will still affect the air. During use, traditional sludge disposal deodorization devices generally place the sludge in a deodorization tank for deodorization. Therefore, the sludge cannot be continuously treated for odor, which reduces the efficiency and thoroughness of the sludge odor treatment process, increases the energy consumption and the number of personnel used by the deodorization device in the process of sludge odor treatment, and the cost of sludge odor treatment is relatively high. Therefore, it is necessary to design a new technical solution to solve the problem. Utility Model Content
