Organic waste aerobic composting test device

Abstract

An organic waste aerobic composting test device comprises a fermentation tank mounted on a fixed rotary shaft, a stirring motor is arranged above the fermentation tank, a stirring shaft in the fermentation tank penetrates through a sealing cover to be connected with the stirring motor, an exhaust port is disposed on the sealing cover and sequentially communicated with a refrigeration dryer in a detection cabinet and a gas detector, a condensate collector is further communicated with a branch of the exhaust port, a temperature control device and an air compressor are communicated with the bottom of the fermentation tank, a leachate discharge outlet is arranged at the bottom of the fermentation tank, a gas distributing plate is arranged on the inner lower side of the fermentation tank, composting materials are reacted in the fermentation tank, the gas detector realizes an analysis function, most of exhausted gas is exhausted to an outdoor environment after flowing through the condensate collector, and temperature data detected by temperature sensors and gas component data detected by the gas detector are displayed on a computer via a PLC (programmable logic control) module in real time. By the aid of the organic waste aerobic composting test device, the temperature of compost, the content of oxygen and the content of carbon dioxide can be detected in real time in an online manner, the data can be remotely looked up at any time and any places, functions are complete, and effects are remarkable.

Description

technical field [0001] The invention relates to solid waste disposal engineering, in particular to an organic waste aerobic composting test device. Background technique [0002] With the rapid development of social economy, the acceleration of urbanization and urbanization process, and the continuous improvement of people's living standards, the amount of municipal solid waste is increasing rapidly. In addition, the management and disposal of solid wastes such as chicken manure, cow manure, and pig manure produced by breeding and animal husbandry, crop straw in agricultural production, and sludge produced by urban sewage treatment plants are important aspects of environmental protection. The level of management reflects the level of social and economic development and civilization of a city or region, is related to the quality of life of the people, and affects the environment and image of the city. [0003] Composting is a biochemical process that uses microorganisms such ...

Problems solved by technology

[0004] There are also some composting test devices at present, but most of them are relatively simple, inconvenient to operate, poor in heat preservation, difficult to raise the temperature, incomplete degradation of organic matter, poor sealing, air leakage seriously pollutes the indoor environment, low degree of automation, and requires manual timing sampling and analysis , labor-intensive, often the test phenomenon is not obvious and the test results are inconsistent with the principle, etc.
