Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment provides a composting device 100 for organic waste, which includes an outer shell 1, a heat exchange assembly 3, an air inlet pipe 6, an air outlet pipe 5 and a leachate collection assembly 4. The upper end of the outer shell 1 is open to facilitate the composting of organic waste. Garbage is put into the outer casing 1 through the opening, and the opening is opened or closed by the coating 2, so that the interior of the outer casing 1 is closed by the coating 2, providing a closed reaction environment, and at the same time, it is convenient for the insulation of the outer casing 1 to improve composting efficiency , the outer shell 1 is used to place organic waste, the heat exchange assembly 3 is used to heat the inside of the outer shell 1 to provide the reaction temperature required for composting, the air inlet pipe 6 and the air outlet pipe 5 can communicate with the inner cavity of the outer shell 1 and The outside ...

Embodiment 2

[0040] This embodiment provides a method for composting organic waste, using the composting device 100 for organic waste in Embodiment 1, comprising the following steps:

[0041] S1. Pile formation: put organic waste into the outer casing 1 to form a pile, and seal the outer casing 1 through the covering film 2 to provide a closed reaction space and facilitate heat preservation in the outer casing 1;

[0042] S2. Initial heating: In the initial stage of composting, sunlight is used to irradiate the heap in the outer shell 1 through the openings of the coating 2 and the outer shell 1, and the heap is in a low-temperature aerobic state, and the heap absorbs the natural heat source of sunlight, Save energy, and at the same time improve the thermal insulation effect combined with the coating 2;

[0043] S3. "Micro-aerobic-anaerobic" cycle: fully irradiating sunlight to gradually increase the temperature of the heap and consume oxygen, and the heap transitions to a micro-aerobic st...

Abstract

The invention discloses a composting device and a composting method for organic garbage, and relates to the technical field of organic garbage treatment. The composting device comprises an outer shell, a heat exchange assembly, an air inlet pipe, an air outlet pipe and a leachate collecting assembly.The upper end of the outer shell is provided with an opening, the opening is connected with a covering film, the covering film can open or close the opening, and the outer shell is used for containing the organic garbage; the heat exchange assembly is used for heating the interior of the outer shell, the air inlet pipe and the air outlet pipe can communicate with an inner cavity of the outer shell and the outside, the end, away from the outer shell, of the air inlet pipe is used for communicating with the induced draft fan, the air inlet pipe is used for introducing oxygen into the outer shell, and the air outlet pipe is used for guiding out waste gas generated in the outer shell; and one end of the leachate collecting assembly is located in the outer shell, the other end of the leachate collecting assembly extends out of the outer shell, and the leachate collecting assembly is used for guiding percolate generated by composting to the outside. According to the composting device and the composting method for the organic garbage, oxygen can be supplied to a pile body while the temperature of the pile body is ensured.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a composting device and a composting method for organic waste. Background technique [0002] Organic waste includes kitchen waste, livestock and poultry manure, agricultural and forestry waste, etc. It is the waste generated after residents' daily life or agricultural activities. If it is not disposed of properly, it will cause harm to the environment. According to statistics, the current annual output of kitchen waste in my country exceeds 200 million tons, and the annual discharge of livestock and poultry manure reaches 4.24 billion tons, but the corresponding disposal capacity is seriously insufficient. The current common organic waste treatment and disposal methods, such as landfill, incineration, composting, etc., all have problems such as large area occupation, secondary pollution, low processing efficiency, and low utilization rate of resources. On the who...
