Deodorization equipment for organic domestic garbage composting process

Abstract

The invention discloses deodorization equipment for an organic domestic waste composting process, the deodorization equipment comprises a primary shell, a primary air inlet, a primary air outlet, a physical treatment chamber, a light treatment chamber, a plurality of vent holes, a stirring rod, a first rotating motor, fan blades, a plurality of activated carbon adsorption balls, a plurality of ultraviolet lamps, a secondary shell, a secondary air inlet, a conduit, an adsorption cylinder, a second rotating motor, a liquid inlet, a sealing cover and a secondary air outlet; the deodorization equipment has a simple structure, and odor generated by composting is pretreated by combining physical and chemical methods, so that the concentration of harmful substances in the odor is reduced to a certain level, and then the odor is introduced into a biological bacteria liquid treatment layer for treatment, so that the concentration is prevented from being too high during biological treatment of the odor, the service life of the biological bacteria liquid is prolonged, the treatment effect of the odor can be ensured, and the service life of the deodorization equipment can be prolonged.

Description

technical field [0001] The invention relates to the field of composting equipment. More specifically, the present invention relates to a deodorizing device for the composting process of organic domestic waste. Background technique [0002] The process of domestic waste composting will go through medium temperature stage, high temperature stage and decomposing stage. In the high temperature stage, the oxygen consumption rate is high, the degradation rate of volatile organic compounds is high, and the odor is very strong. The odor generated needs to be treated before being discharged into the atmosphere. [0003] The existing compost deodorization methods can be divided into physical methods, chemical methods and biodegradation methods. The physical methods are mainly adsorption, absorption, and concentration. The chemical methods are mainly chemical washing, thermal oxidation, catalytic oxidation, and ozone oxidation. The biodegradation method is Biofiltration, biowashing, b...

Problems solved by technology

[0004] However, there are some defects in the use of biodegradation methods, for example, the service life is short, and the amount of adsorbed gas is limited, and the generated odor cannot be efficiently treated. If the concentration of odor is too high, the biodegradation rate will slow down, and the overall deodorization not effectively
