Aerobic composting device for organic solid waste

Abstract

The invention discloses an aerobic composting device for organic solid waste, which comprises a feeding mixer, a conveyor, a fermentation tower, a scraper blade drive device, an air blower, a heating device, an exhaust fan, a waste gas processing device, centre discharge trays, periphery discharge trays, a swivel type granulator, a granulator drive device, a return conveyor, a granulating agent adding device and a spiral conveyor. The aerobic composting device is characterized in that a conical sealing cover is arranged above the fermentation tower, the swivel type granulator is arranged below the fermentation tower; the feeding mixer is connected with the feeding opening in the side surface of the sealing cover through the conveyor; an inward scraper blade is arranged above the centre discharge tray, and an outward scraper blade is arranged above the periphery discharge tray; and two or more groups of the centre discharge trays and the periphery discharge trays are arranged in the fermentation tower from top to bottom. The aerobic composting device for the organic solid waste disclosed by the invention has the characteristic of processing the organic solid waste in a quantity-reduction, stable and harmless manner to realize resource recycling; in addition, the device occupies a small space and also has the characteristics of automatic feeding, granulating, self-control venting, temperature controlling and tail gas processing.

Description

technical field [0001] The invention relates to the technical field of composting, in particular to an aerobic composter for organic solid waste. Background technique [0002] With the acceleration of urbanization, the amount of solid waste is increasing, especially the amount of urban garbage and sewage is increasing, resulting in more and more urban organic waste and sludge from sewage treatment plants. Recycling resources and resources from solid waste Energy, reducing the amount of waste for final disposal, thereby reducing its environmental pollution load, has become an urgent problem to be solved. The purpose of solid waste disposal mainly has the following four aspects: reduction: reduce the volume of solid waste before final disposal, so as to reduce the cost of solid waste treatment and final disposal; stabilization: stabilize solid waste through treatment to avoid secondary Secondary pollution; Harmless: To achieve harmless and sanitation of solid waste, such as r...

AI Technical Summary

Problems solved by technology

[0003] Existing traditional aerobic composting technologies include open-air strip stacking, static forced ventilation, and horizontal dynamic closed composting, etc., all of which occupy a large area and are difficult to control the operating conditions of aerobic composting. Produce malodorous gas and affect the surrounding environment. Because of the lack of nutrients required for fertilizers, the value of the final compost product is not high, and it is difficult to realize the industrialization of compost
