A device and method for adjusting the temperature of pipeline fluid used for food waste composting

Abstract

The invention provides a pipeline fluid temperature adjustment device and method for composting kitchen waste. The device for adjusting the temperature of the pipeline fluid used for composting food waste includes a movable compost bucket, an annular pipeline, a thermostat and a water pump. The method for adjusting the temperature of the pipeline fluid used for composting food waste can adopt different temperature adjustment methods according to the temperature of the external environment. The invention aims at the problem that the heating and cooling stages of the aerobic composting of food waste are not at the same time, and a large amount of energy needs to be consumed to heat up or cool down when ensuring a suitable temperature for composting. Under the action of the device, the temperature adjustment range in the pipeline is variable, and at the same time, the heat in different temperature stages is recycled for temperature adjustment, which solves the problem of excessive energy consumption for raising and lowering the temperature.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a device and method for adjusting the temperature of pipeline fluid used for composting food waste. Background technique [0002] Aerobic composting is the process of continuously decomposing and transforming organic matter rich in biomass, including rice and flour food residues, vegetables, etc., under the condition of oxygen, with the help of aerobic microorganisms (mainly aerobic bacteria). Aerobic composting is generally divided into three stages: [0003] 1. The heating stage (heat production stage) refers to the initial stage of composting. In this stage, the temperature of the compost gradually rises from the ambient temperature to about 45°C. The dominant microorganisms are mainly mesophilic microorganisms, including fungi, bacteria and actinomycetes. The decomposition substrates are mainly sugars and starches. [0004] 2. In the high temperature stage, the pi...

AI Technical Summary

Problems solved by technology

Existing aerobic composting technology is mainly carried out in a composting chamber. Since the heating and cooling are not at the same time, a large amount of energy is required to heat up or cool down when ensuring the above temperature conditions, and it is difficult to solve the contradiction between heating and cooling in different temperature ranges.
