Garbage composting energy-saving consumption-reducing and waste gas zero-emission system and method based on zero-emission architecture

Abstract

The embodiment of the invention discloses a garbage composting energy-saving consumption-reducing and waste gas zero-emission system and method based on a zero-emission architecture. The system comprises a comprehensive workshop, fermentation workshops, a turner collection cover, a first deodorization system, a second deodorization system, a first exhaust fan, a second exhaust fan and a flow guide, replacement, air supply and collection device. The flow guide, replacement, air supply and collection device is used for realizing gas circulation of the comprehensive workshop and the fermentationworkshop and guiding gas to the first deodorization system. The deodorization system is used for purifying the introduced gas. The first exhaust fan is used for conveying the purified gas into the comprehensive workshop. The turner collection cover is used for collecting water vapor, dust and odor brought out by turners in the fermentation workshops, and the water vapor, the dust and the odor areconveyed to a longitudinally-arranged exhaust pipeline through a high-pressure axial flow exhaust fan arranged at the upper end of the turner collection cover and are converged into the connected second deodorization system. The second exhaust fan is used for conveying the gas purified by the second deodorization system into the comprehensive workshop. According to the scheme, the gas flow state is reasonable, and zero emission of waste gas treatment is achieved.

Description

technical field [0001] The embodiments of the present application relate to the field of environmental protection technology, and in particular to a waste composting system and method based on a zero-emission framework for energy saving and consumption reduction and zero emission of exhaust gas. Background technique [0002] Composting refers to the biochemical process of using microorganisms that exist widely in nature to promote the conversion of degradable organic matter in solid waste into stable humus in a controlled manner. Composting is a process of producing organic fertilizer. It contains rich nutrients and has a long and stable fertilizer effect. The mixed use of chemical fertilizers can make up for the single nutrient contained in chemical fertilizers, and the long-term single use of chemical fertilizers will cause soil compaction, water retention, and fertilizer retention. Composting is the use of various organic wastes (such as crop straw, weeds, leaves, peat, ...

Problems solved by technology

[0005] The embodiment of the present invention provides a waste composting energy-saving and consumption-reducing system and method based on a zero-emission architecture and zero-emission of waste gas. For the problem of long-term stability, the waste gas in the workshop is collected by diversion and replacement. A large amount of odor containing dust and water vapor generated during the operation of the turning machine is collected by sliding seals. The gas flow state is reasonable and the collection is thorough. The invention is on the same scale as the traditional one. Compared with the composting capacity, the sludge composting deodorization process is optimized, the investment cost is reduced, the treatment scale is reduced, the operating cost is reduced, the cost performance is high, and it has good economic benefits
