Description

TECHNICAL FIELD

[0001] The utility model relates to garbage treatment technical field, concretely is garbage landfill exhaust device. BACKGROUND

[0002] At present, the garbage is mainly taken the way of landfill. The landfill gas is the product of the organic matter in the domestic waste in the fermentation process, and its yield and nature are related to the structure of the garbage landfill, the landfill technology, the moisture content of the garbage, the time of landfill, the gas pressure, etc. For different garbage components, different landfill years, with the different decomposition rates of organic matter, the yield of landfill gas is also different. The more the organic matter content in the general garbage component, the larger the volume of the landfill area, the deeper the landfill depth, the better the sealing degree of the landfill, the more reasonable the design of the gas collection facility, the higher the gas yield. The main components of the garbage landfill gas are methane and carbon dioxide. Methane is a high-calorific-value combustible gas. If not properly disposed, it will cause harm. If used properly, it is also a good energy source.

[0003] The existing patent with the patent number CN210304990U discloses a garbage landfill exhaust device, which comprises an exhaust cylinder and a gas pump. A plurality of connecting heads are arranged on the outer side wall of the exhaust cylinder. The exhaust cylinder is connected with a hose through the connecting heads. A plurality of air inlet holes are formed in the side wall of the hose. When landfill is carried out, the hose can be laid in the garbage layer, and the laying density of the hose is determined by bending. The density of the hose can be arranged according to the type of garbage and the volume of the landfill area. The gas generated in the garbage enters the inside of the hose through the air inlet holes and is finally collected in the inside of the exhaust cylinder. The top of the exhaust cylinder is connected with the gas pump through the gas pipe. Under the action of the gas pump, the gas in the inside of the exhaust cylinder is extracted, so that the gas is passively sucked out, and the exhaust capacity is improved. After analyzing the device, it can be found that when collecting waste gas, the hose is distributed in the garbage. The hose is easily deformed under the extrusion of the garbage, which causes the air inlet on the hose to be blocked, affecting the entry of waste gas. After the waste gas is burned, there is a lack of subsequent filtration treatment, which causes a large amount of pollutants to be contained in the waste gas when it is discharged, polluting the air.

[0004] Therefore, in view of the above problems, the technical scheme provides a garbage landfill exhaust device. UTILITY MODEL CONTENTS
