Mobile composting odor collection system

Abstract

The invention relates to a mobile composting odor collection system. The mobile composting odor collection system comprises an exhausting pipeline and a gas collection device, wherein the exhausting pipeline comprises an exhausting main pipe and a plurality of exhausting branched pipes, the exhausting branched pipes are respectively mounted right above a fermenting slot, and one ends of the exhausting branched pipes are communicated and connected with the exhausting main pipe; the exhausting branched pipes are respectively of a steel channel structure, openings of the exhausting branched pipesface downwards, sealing rubber strips which are mutually matched to form a self-closing structure are arranged on two sides of the openings along the length direction, and sliding rails are arrangedon the exhausting branched pipes along the length direction; the gas collection device comprises a gas collection cover and a trolley and is mounted behind a pile turning machine, the trolley is mounted on the sliding rails of the exhausting branched pipes, exhausting flexible pipes are mounted on the trolley, and the upper ends of the exhausting flexible pipes are inserted into the exhausting branched pipes; and exhausting holes are formed in the top of the gas collection cover, and the lower ends of the exhausting flexible pipes are inserted into the exhausting holes. The system has a very good effect on the collection of odor produced in the trench type composting turning process.

Description

technical field [0001] The invention relates to the fields of environmental engineering and agricultural engineering. Specifically, it relates to a mobile compost odor collection system during the fermentation and decomposing process of organic compost materials in the fields of sludge composting, agricultural solid waste composting, and edible fungus cultivation base material composting. Background technique [0002] Using agricultural solid waste and municipal sludge as raw materials for composting treatment is an effective way to realize organic waste reduction, harmlessness, resource recycling, and has positive significance for the "two-oriented society" and the construction of ecological civilization. . However, due to the complex composition of organic materials, the odor generated during composting production has a greater impact on the environment. Developed countries such as Europe and the United States use closed stainless steel tank fermentation technology for wa...

Problems solved by technology

Can only work intermittently, not continuous operation

Moreover, the gas generated during the turning operation contains ammonia, hydrogen sulfide and other corrosive gases, which is easy to cause corrosion to the equipment itself, especially in winter operation, a large amount of water vapor will cause short circuits to machine components, power units and control units, which is easy cause electric shock

The gas collecting hood can only collect the odor when the material is raised during the operation of the compost turner, and cannot suppress the odor that escapes when the material cools down after the compost turner. The odor type has a great impact on the air environment, so it must be controlled
