Combined composting device of park waste and kitchen waste

Abstract

The invention discloses a combined composting device of park waste and kitchen waste. The combined composting device comprises a smashing layer, a drying layer and a composting layer. The park waste and kitchen waste are mixed for composting, so satisfied C / N is acquired. Fermentation equipment is highly integrated, and smashing, drying and composting are integrated, so equipment standardized andmodularized production can be realized, and park waste and kitchen waste problems in areas of an industrial park, a park, a school and the like can be solved, and local resource utilization of two types of the waste can be realized without departing from a generating place. The upper drying layer is heated by using heat generated by compost at a bottom layer, so a problem that water content is high after two types of materials are smashed and directly composted is solved, and waste of the heat generated by the composting layer can be reduced. Two smashing chambers of the device can be closed while unused, safety is guaranteed and bad smell generated from the interior of the device is guaranteed to be discharged from a tail gas discharging chamber. The device is environment-friendly, and odourless in a running process.

Description

technical field [0001] The invention relates to the technical field of environmental protection machinery, in particular to a combined composting device for garden waste and kitchen waste Background technique [0002] With the acceleration of urbanization and the improvement of people's living standards, the output of garden waste in urban areas is increasing day by day, and the output of kitchen waste is also increasing day by day. Traditional garden waste treatment methods are mainly incineration and landfill. These two treatment methods not only cause waste of resources, but also pollute the environment if they are not handled properly, which are not suitable for the development needs of circular economy. However, food waste is easy to ferment, deteriorate, and rot, which not only produces a large amount of toxins and emits foul-smelling gases, but also pollutes water bodies and the atmosphere. Therefore, it is necessary to realize the harmless treatment of food waste in ...

AI Technical Summary

Problems solved by technology

Traditional garden waste treatment methods are mainly incineration and landfill. These two treatment methods not only cause waste of resources, but also cause pollution to the environment if they are not handled properly, which are not suitable for the development needs of circular economy.

However, food waste is easy to ferment, deteriorate, and rot, which not only produces a large amount of toxins, emits foul-smelling gases, but also pollutes water bodies and the atmosphere. Therefore, it is necessary to realize the harmless treatment of food waste in a timely and effective manner.
