Simulator for aerobic high-temperature composting of solid waste

Abstract

The invention discloses a simulator for the aerobic high-temperature composting of solid waste, which comprises a composting ventilation control system and a composting barrel assembly, wherein the composting barrel assembly comprises an outer barrel (3) and an inner barrel (4) sleeved in the inner cavity of the outer barrel (3); a seal element (6) is arranged between the top of the side wall of the outer barrel (3) and the top of the side wall of the inner barrel (4); a hollow cavity (5) defined by the outer barrel (3) and the inner barrel (4) is communicated with at least one air duct (7); the surface of the inner barrel (4) is provided with small air vents (41); the composting ventilation control system comprises an air flow meter (8) and an air pump (9) which are communicated with each other, and the air flow meter (8) is communicated with each air duct (7); and a time controller (10) is in signal connection with the air pump (9). The simulator can be repeatedly used for aerobic high-temperature composting simulation tests of solid waste in a multiprocessing mode.

Description

technical field [0001] The invention relates to a solid waste aerobic high-temperature composting simulation device, which is suitable for small-scale multi-processing and multi-repetitive composting test research. Background technique [0002] Aerobic high-temperature composting technology is a kind of harmless and resourceful treatment and utilization technology of domestic garbage, poultry manure, sludge, crop straw and other organic solid wastes that are widely used at home and abroad. However, in the optimization of composting technology and the research on the mechanism of the composting process, it is necessary to carry out composting experiments with various treatments, such as the effect of different conditioners on nitrogen loss in the composting process, and the effect of different composting fermentation-promoting bacterial agents on compost maturity. The impact test of the process, the impact test of different composting process parameters such as aeration inten...

Problems solved by technology

At present, many composting devices are mostly equipped with heaters, mechanical supports, automatic turning equipment, etc., and the design is complicated. For example, an external heating type composting device disclosed in the invention patent 02139893. There is a compost bin with a constant temperature hot water insulation layer between the outer walls, a stirring device composed of a motor and a stirring mechanism, and a ventilation device and other components; the HC-01 deep groove spiral stirring composting device designed by Zhang Hua et al. Composition of trolley, stirring screw, hydraulic system, electric control system and fermentation tank (Zhang Hua, Li Xiujin, Cai Luping, Pang Yunzhi. Development of HC-01 deep tank spiral stirring composting device. Agricultural Mechanization Research, 2008(3): 222-224), Because these composting devices are not only expensive, but also occupy a relatively large area, it is not convenient to carry out composting experiments with multiple treatments and multiple repetitions under laboratory conditions.
