Film covered aerobic compost dual-purpose gas and pressure monitoring device

Abstract

The invention discloses a film covered aerobic compost dual-purpose gas and pressure monitoring device which comprises a gas real-time analysis device which can communicates with the gas in a film covered aerobic compost system, a pressure transducer which can communicates with the gas in the film covered aerobic compost system, and a data acquisition and processing terminal which is electrically connected to the pressure transducer and the real-time analysis device. When the film covered aerobic compost dual-purpose gas and pressure monitoring device is used, both the gas real-time analysis device and the pressure transducer communicate with the gas in the film covered aerobic compost system, since the pressure transducer and the gas real-time analysis device are electrically connected to the data acquisition and processing terminal, the gas real-time analysis device transmits a signal obtained by collection and analysis to the data acquisition and processing terminal, the pressure transducer transmits a detected pressure signal to the data acquisition and processing terminal, and a detected index is displayed and recorded. According to the film covered aerobic compost dual-purpose gas and pressure monitoring device, the simultaneous detection of a pressure index and a gas index is realized, time and labor are saved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of organic solid waste disposal and resource utilization, in particular to a film-covered aerobic composting dual-purpose gas and pressure monitoring device. Background technique [0002] At present, livestock and poultry farming waste and straw are usually utilized in the form of aerobic composting. Aerobic composting is a process in which organic solid wastes such as livestock manure and straw are decomposed into stable and decomposed organic fertilizers by the decomposition of microorganisms under the condition of ventilation and oxygen supply. At present, the application technology mode of aerobic composting in my country is trough aerobic composting with turning and stirring. [0003] In order to solve the problems of uneven fermentation, more gas production and high energy consumption in the trough aerobic compost with turning and stirring, the surface of the original compost stack is usually covered ...

AI Technical Summary

Problems solved by technology

[0004] In the process of film-covered aerobic composting, the real-time changes in the pressure and gas in the compost are very important to the compost. At present, it is necessary to separately detect the pressure index and gas index, which is time-consuming, laborious and inefficient.
