Composting reactor system capable of achieving intelligent layered aeration

Abstract

The invention discloses a composting reactor system capable of achieving intelligent layered aeration. The composting reactor system capable of achieving the intelligent layered aeration comprises a tank, a feeding system, a discharging system, a stirring system, an aerating system and a control part, wherein a plurality of supporting beams with different heights are arranged inside the tank; the aerating system comprises aerating pipelines, gas concentration sensors, a gas supply manifold and valves; the aerating pipelines are arranged on first side surfaces of the supporting beams and are provided with a plurality of aerating holes; the gas concentration sensors are arranged on second side surfaces of the supporting beams and are used for detecting the concentration of predetermined gas at the heights of the supporting beams inside the tank; the gas supply manifold is communicated with each aerating pipeline and supplies gas; each valve is arranged inside each aerating pipeline, is positioned at a connecting end of each aerating pipeline and the gas supply manifold, and can be opened and closed under the control of the control part. When the gas concentration sensor arranged on the supporting beam detects that the concentration of the predetermined gas is lower than or higher than a predetermined value, the valve in the aerating pipeline arranged on the same supporting beam is opened under the control of the control part so as to aerate the tank through the aerating holes.

Description

technical field [0001] The invention relates to an intelligent composting reactor system, which belongs to the technical field of resource utilization of organic waste. Background technique [0002] With the development of animal husbandry in the direction of intensification and scale, the amount of manure produced by livestock and poultry is large and concentrated, and the total amount of livestock and poultry produced every year is as high as 4 billion tons. The extensive use of antibiotics has led to the intensive development of agriculture in livestock and poultry manure, resulting in a large amount of concentrated production of crop straw and livestock and poultry manure, which greatly increases the difficulty of agricultural waste disposal, aggravates the risk of soil, water and air pollution, and poses a threat to the environment. Integrated governance poses enormous challenges. Therefore, the use of biotechnology—especially composting technology has become one of th...
