Integrated negative pressure sterilization and deodorization garbage treatment device

Abstract

The invention belongs to the field of garbage treatment, and relates to an integrated negative pressure sterilization and deodorization garbage treatment device which comprises a feed port, a butterfly valve air inlet, an anaerobic tank, a facultative tank, an aerobic tank, a stirring device, a pressure transmitter, a deodorization device, a fan system, a PLC control system, a discharge port, an air outlet, an ozone generator and a catalyst honeycomb. An air inlet of the butterfly valve is installed on the shell of the device and connected with the anaerobic tank, stirring devices are installed in the anaerobic tank, the facultative tank and the aerobic tank, partition plates are arranged among the anaerobic tank, the facultative tank and the aerobic tank, an air inlet of the deodorization device is connected with the aerobic tank through a pipeline, and an air outlet of the deodorization device is connected with the fan system. And the ozone generator and the catalyst honeycomb are respectively arranged on the clamping groove and the grating of the deodorization device. And the pressure transmitter and the fan system are connected with the PLC control system. According to the equipment, the full-negative-pressure design of the garbage treatment device is achieved, deodorization and sterilization equipment and garbage treatment equipment are integrated, efficient sterilization and peculiar smell removal are achieved, and the environment around the device is improved.

Description

technical field [0001] The invention relates to an integrated negative pressure sterilization and deodorization garbage disposal device. Background technique [0002] The biological fermentation waste treatment device is gradually recognized by the market due to its high decomposition efficiency. However, the waste gas discharged from the biological fermentation treatment device often contains high concentrations of bacteria and odor, which seriously affects the surrounding environment. [0003] However, there is no complete long-term effective way in the industry to deal with the problem of odor emitted by waste deodorization devices. For example, activated carbon adsorption towers are inefficient and easily saturated, and the cost is high. The efficiency of ozone oxidation technology is low and there is the problem of ozone residual pollution to the environment. , the selectivity of the spray tower is too high, it is only effective for part of the gas and the volume is la...

Problems solved by technology

However, the waste gas discharged from the waste after being treated by the biological fermentation treatment device often contains high concentrations of bacteria and stench, which seriously affects the surrounding environment.

[0003] However, there is no long-term effective method in the industry for the problem of gas odor emitted by garbage deodorization devices. For example, the efficiency of activated carbon adsorption tower is low and it is easy to be saturated and the cost is high. The efficiency of ozone oxidation technology is low and there is the problem of residual ozone polluting the environment , the selectivity of the spray tower is too high, it is only effective for part of the gas and the volume is large, and it cannot be well integrated with the entire waste treatment device
