Description

Technical Field

[0001] The utility model relates to the technical field of agricultural engineering, in particular to a gas collection rod in an aerobic composting pile of livestock and poultry excrement. Background Art

[0002] If livestock and poultry manure, especially livestock and poultry manure from large-scale farms, is not properly handled, it will cause environmental pollution. Aerobic composting of livestock and poultry manure is an excellent technical means for resource utilization and harmless treatment of livestock and poultry manure. There are many traditional processes for aerobic composting of livestock and poultry manure. Ordinary farmers and small farms mostly use static windrow aerobic composting technology, which has the main advantages of low cost, rough management, and low technical requirements. Its main disadvantage is that the fermentation cycle is usually more than 50 days, and the fermentation uniformity of livestock and poultry manure is poor, which is not conducive to large-scale production of projects. In order to shorten the fermentation cycle of aerobic composting of livestock and poultry manure, large-scale farms and organic fertilizer production enterprises generally add a certain proportion of fermentation agents to the livestock and poultry manure raw materials, and then adopt an aerobic composting process combining forced ventilation and intermittent composting, which can shorten the aerobic composting fermentation cycle of livestock and poultry manure to less than 40 days. However, the aerobic composting process combining forced ventilation and intermittent composting has high requirements for infrastructure and technology, more intermittent composting times, large one-time investment, and relatively high cost.

[0003] By using a suitable gas collection device inside the pile and accurately controlling the key gas parameters in the aerobic composting pile of livestock and poultry manure, the timing of turning the pile and aeration can be grasped in time, the fermentation environment inside the pile can be kept stable, and the unnecessary turning and aeration costs can be effectively reduced. Therefore, the gas collection inside the aerobic composting pile of livestock and poultry manure is very important for the improvement of the aerobic composting process and technology of livestock and poultry manure. In different fermentation stages, the pile of aerobic composting of livestock and poultry manure has the characteristics of high temperature, high humidity, high dust and high particles. Therefore, the real-time online collection of the gas inside the pile faces the problems of particle removal, dust removal and water removal, and the particles, dust and water vapor in the gas will seriously affect the detection results of the gas sensor. In order to ensure the accuracy of the online detection results of the gas inside the pile, the problems of particles, dust and water vapor in the gas inside the pile must be solved during the gas collection process inside the pile.
