Description

Air circulation system of small-size distributed perishable garbage on-site treatment equipment

Technical Field

The utility model discloses an air circulation system of small-sized distributed perishable garbage in-situ treatment equipment, and relates to the field of environment-friendly equipment.

Background

With the improvement of the living standard of people in China and the continuous promotion of the urbanization process, the generation amount of perishable organic solid wastes is increased year by year. The perishable organic solid wastes are mainly derived from agricultural wastes, industrial wastes and household wastes.

At present, the common perishable organic solid waste treatment technologies at home and abroad include drying incineration, sanitary landfill, anaerobic digestion, aerobic composting, ecological feed and the like. Each method has advantages and disadvantages: (1) drying and incinerating: can completely oxidize and decompose organic components in the organic solid waste, and the reduction rate is up to 50-80%. However, some organic solid wastes (such as kitchen wastes) have high water content, are not suitable for being directly burnt in an incinerator, and need to be subjected to drying pretreatment. (2) Sanitary landfill: burying organic solid waste underground, and degrading macromolecules into micromolecules by using various microorganisms. The method has low treatment cost and simple technology, is suitable for various organic solid wastes, and is applied more in developing countries. But has great potential safety hazard, the produced methane and other gases can explode, the percolate easily pollutes the underground water, and meanwhile, the resource recovery and utilization rate is basically zero, a large amount of land is occupied, and the method is not suitable for areas with short land use. (3) Anaerobic digestion: the capacity reduction and resource utilization of the organic solid wastes are realized by using the metabolism of facultative/anaerobic microorganisms under the anaerobic condition. The automatic control system has the advantages of high automation degree, less manpower, easy control of malodorous gas emission, product diversification and high economic value. But the requirement of microorganisms on the pH value is high, the treatment technology is relatively complex, and the biological start-up time in the reactor is long; the treatment of biogas slurry and biogas residue generated by anaerobic fermentation is still a great problem. (4) Aerobic composting: and (3) carrying out biodegradation on organic matters in the organic solid waste by utilizing aerobic microorganisms under an aerobic condition to finally form stable high-fertility humus. The technology is simple, convenient to popularize and high in resource utilization rate. But the occupied area is large, the composting process generates odor, and the economic benefit is not high. (5) Ecological feed: certain organic solid wastes (such as kitchen waste) are fermented to produce the ecological feed.

In the 5 th method, the high-temperature fermentation technology of aerobic bacteria is mainly adopted to degrade the kitchen waste in the equipment for a period of time. The product of the equipment is organic particles which are packaged in dry powder without peculiar smell and can be directly used for on-site greening maintenance. The concentrated compost can be made into high-efficiency natural organic fertilizer for fertilizing green organic crops.

In the process of converting the technology into equipment, the temperature in the equipment needs to be maintained at about 40 ℃ during fermentation, and the energy consumption is high.
