Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, in particular to a landfill gas collection and deodorization device for a garbage landfill. Background Art

[0002] Most of the domestic waste is transported to landfills for treatment. During the accumulation and treatment process, a large amount of odor is often produced. Odor refers to any substance that stimulates the olfactory organs, causes discomfort to people and damages the biological environment. Odor will have an adverse effect on the air environment and living environment around the treatment site as well as the staff of the treatment site. Therefore, it is usually necessary to collect and treat the gas in the landfill.

[0003] There are many ways to treat odor, such as biological decomposition, absorption and adsorption, chemical oxidation, dilution and diffusion, combustion, etc. At the same time, landfill disposal is the main way to dispose of domestic waste. However, the stench seriously troubles the lives of residents, especially those living around landfills. The stench of garbage has always been a headache. Deodorants use efficient adsorption, chemical decomposition or biodegradation technology to directly act on odor molecules such as hydrogen sulfide and ammonia generated by landfills, effectively neutralizing and reducing their concentration. This treatment method is not only fast and effective, but also can significantly improve the air quality of landfills and surrounding areas, contributing to environmental protection. The application of deodorants makes the garbage disposal process more environmentally friendly and provides residents with a more livable living environment.

[0004] In the related technology, the patent with patent application number 202411314437.2 discloses an odor collection and treatment device in an urban landfill, including an odor treatment device body; an air collecting box is installed on the odor treatment device body, a reaction chamber is opened in the air collecting box, a spray diffusion mechanism is provided in the reaction chamber, the spray diffusion mechanism includes a motor, a motor is installed on the top of the air collecting box, a motor gear is installed on the motor, a center shaft is rotatably installed on the top of the air collecting box, and a center shaft sleeve is sleeved on the center shaft; the above-mentioned related technology sucks the malodorous gas into the reaction chamber through an air suction component, and the deodorant in the deodorant storage tank is sprayed into the reaction chamber through a nozzle, and then the atomized deodorant and the inhaled malodorous gas are stirred and mixed through the spray diffusion mechanism, and the deodorant fully reacts with the malodorous gas to avoid the situation where the odor and the deodorant are not mixed thoroughly, the reaction is not complete, and the deodorant effect is not good. At the same time, the deodorant is used as much as possible to prevent waste. The positioning rod is inserted into the garbage pile through the auxiliary fixing mechanism, so that the equipment can still run smoothly on the garbage pile formed by the landfill, preventing the equipment from overturning due to excessive inclination. The positioning rod is fixed in the rod fixing ring through the anti-loosening mechanism to prevent the positioning rod from loosening when using or mounting the positioning rod, so that the equipment can adapt to the uneven use environment in the garbage dump.

[0005] In the related technology, the patent with patent application number 201920278569.2 discloses a landfill odor treatment device, including: a gas collection mechanism, a biological treatment tank, an air inlet pipe, a stirring mechanism, an air outlet pipe, an air outlet pump, an adsorption treatment column and an exhaust pipe. The gas collection mechanism includes a coating, a plurality of gas collecting pipes, an exhaust pipe, an exhaust pump and a gas collecting box. The gas collecting pipe is arranged on the coating. The gas collecting pipe is provided with air holes. A first air pressure sensor is arranged in the gas collecting box. The air inlet pipe is provided with a first valve. The stirring mechanism includes a stirring motor, a stirring shaft and a stirring blade. The adsorption treatment column is provided with a non-woven fabric filling layer and an activated carbon adsorption layer. In the above-mentioned related technology, a film is provided, which can be covered on the garbage dump to control the emission of odor. The odor can be extracted and collected into the air collecting box through the gas collecting pipe provided on the film in cooperation with the vacuum pump. The air collecting box is provided with a first air pressure sensor, which can detect the air pressure of the odor in the air collecting box. When the odor collection reaches the preset air pressure, the first valve is opened, and the stirring motor and the air outlet pump are started to centrally treat the odor, saving energy. The adsorption treatment column is provided with a non-woven fabric filling layer, which can remove moisture from the odor and avoid the activated carbon adsorption layer directly treating the odor. The moisture in the odor affects the adsorption effect of the activated carbon adsorption layer, so that the activated carbon adsorption layer is used more for adsorption and deodorization, thereby increasing the service life of the activated carbon adsorption layer and improving the odor treatment effect of the device.

[0006] The above-mentioned related technologies can only collect the gas above the garbage layer, and do not have the function of extending into the inner layer to synchronously adsorb the gas, resulting in low overall adsorption efficiency, and further resulting in low efficiency of the entire treatment process.

[0007] Existing devices for collecting and treating gases in landfills can usually only collect gas above the garbage layer. However, there is also a large amount of gas covered below the garbage pile, which will gradually diffuse to the outer layer and into the air. Simply collecting the outer layer gas will result in low overall collection efficiency and reduce the overall treatment efficiency.

[0008] Therefore, there is an urgent need for a landfill gas collection and deodorization device to solve the above problems. Summary of the invention
