An intelligent composting reactor system and a composting reactor

Abstract

An intelligent composting reactor system is disclosed. The system includes a reactor tank body, a temperature monitoring part used for monitoring the temperature inside the tank body, a vacuum pump, an oxygen concentration monitoring part used for monitoring the oxygen concentration inside the tank body, a gas condensing part, a heating and insulating part and a PLC control part. The bottom of the reactor tank body is provided with a first gas port and the top of the reactor tank body is provided with a second gas port. A gas distributing screen is arranged along the radial direction at the inner lower part of the reactor tank body. An aeration pipeline is disposed under the gas distributing screen. The aeration pipeline is isolated from a material by utilizing the gas distributing screen. The aeration pipeline is provided with a plurality of aeration holes and is communicated with the first gas port. The first gas port is connected to the vacuum pump through the gas condensing part. The vacuum pump can perform gas exhausting to form a negative pressure in the reactor tank body. The gas condensing part is used for condensing water vapor in exhausted reaction tail gas. The heating and insulating part is attached to the reactor tank body. The PLC control part is connected to the vacuum pump, the heating and insulating part, the temperature monitoring part and the oxygen concentration monitoring part.

Description

technical field [0001] The invention relates to an intelligent composting reactor system and belongs to the technical field of organic waste resource utilization. Background technique [0002] As a large agricultural country, China produces up to 4 billion tons of agricultural waste every year. The development of agricultural intensification has led to the 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 huge challenge to the comprehensive management of the environment. Therefore, the use of biotechnology—especially composting technology has become one of the important ways for countries all over the world to realize the reduction, harmlessness and resource utilization of organic waste. Among them, the multi-dimensional system of processing planting and breeding waste and producing organic fertilizer not only solves ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the object of the present invention is to provide an intelligent composting reactor system, which can adopt two composting modes, positive pressure and negative pressure, to realize the effective recycling and treatment of composting tail gas, and solve the problem of existing composting problems. The ammonia volatilization in the reactor system is serious, the recovery and treatment of odor is difficult, the heat loss of composting, the temperature and moisture distribution of materials are uneven, etc.
