Film mulching aerobic composting reactor test apparatus

Abstract

The invention relates to a film mulching aerobic composting reactor test apparatus. The film mulching aerobic composting reactor test apparatus comprises a film system, a tank body, a gas distribution sieve, sensor groups, a first pressure sensor, a right-angle elbow, a second pressure sensor, a filtrate collector, a gas inlet, a gas distribution system and a PLC control system. The film system is connected with the top of the tank body by virtue of a hollowed stainless steel ring. The gas distribution sieve is arranged on the lower part in the tank body; and three sensor groups are positioned above the gas distribution sieve and on the side wall of the tank body at intervals. The first pressure sensor is arranged on the top end of one side wall of the tank body; and the second pressure sensor is arranged at one side of the bottom of the tank body. The center position of the bottom of the tank body is connected with the filtrate collector by virtue of a pipeline, the gas inlet is formed in the pipeline, and the gas inlet is connected with the gas distribution system by virtue of a pipeline. The gas distribution system, each sensor group and each pressure sensor are separately electrically connected with the PLC control system, and the operation of the gas distribution system is controlled by the PLC control system. The test apparatus is compact in layout, convenient to operate and intelligent in monitoring.

Description

technical field [0001] The invention relates to a test device, in particular to a film-covered aerobic composting reactor test device used in the technical field of organic solid waste disposal and resource utilization. Background technique [0002] At present, the annual discharge of livestock and poultry manure in my country is about 2 billion tons, and it is showing an upward trend. However, the effective treatment and resource utilization rate of livestock and poultry manure in my country is still relatively low. At the same time, my country's annual straw production is about 7 To 900 million tons, of which more than 20% of the straw has not been rationally utilized. The "National Agricultural Sustainable Development Plan (2015-2030)" clearly proposes to achieve sustainable agricultural development, and by 2030, the country will basically achieve zero discharge of agricultural waste. [0003] Aerobic composting refers to the process in which organic solid waste such as a...

Problems solved by technology

However, there is still a lack of systematic research on the mechanism and mechanism of film-covered aerobic composting. If the factory composting model is adopted, it will not only require a large number of large-scale experiments with a large amount of engineering, but also be easily affected by factors such as the environment, with low efficiency, high cost, and cycle time. longer
