Description

TECHNICAL FIELD

[0001] The utility model relates to a filter for biogas treatment. BACKGROUND

[0002] Biogas can be directly combusted for cooking, drying agricultural and sideline products, heating, lighting and gas welding, etc., and can also be used as fuel for internal combustion engines and as a chemical raw material for producing methanol, formalin, carbon tetrachloride, etc. The material liquid and sediment discharged after fermentation by a biogas device contain rich nutrients and can be used as fertilizer and feed. Biogas combustion for power generation is a biogas utilization technology that emerged with the continuous development of large-scale biogas pond construction and biogas comprehensive utilization. It uses the biogas produced by anaerobic fermentation treatment for an engine and is equipped with a comprehensive power generation device to generate electric energy and heat energy. Biogas power generation has the characteristics of creating benefits, saving energy, safety and environmental protection, etc. and is a widely distributed and inexpensive distributed energy source.

[0003] The filter for biogas treatment disclosed in patent publication No. CN210163400U allows the biogas entering through the gas inlet to flow out through the gas outlet after passing through the gas inlet chamber, the drying chamber and the gas outlet chamber, and is fully dried in the process of passing through the drying chamber. Before entering the gas inlet chamber, the biogas is dispersed by the gas distribution block, so that the biogas can enter the drying chamber more uniformly, further improving the drying effect.

[0004] However, the above filter lacks odor treatment technology for biogas. Since biogas is produced by fermentation from fecal pollution, the gas itself carries residual gas of fecal pollution and produces odor. If the odor is not cleaned and purified, it will affect the subsequent utilization effect of biogas. The existing technology mostly uses activated carbon to adsorb the odor of biogas. The activated carbon needs to be replaced in time after being used for a period of time, otherwise it will be invalid. If it is used in the filter, it is not convenient to replace it in time.

[0005] Therefore, the skilled in the art provides a filter for biogas treatment to solve the problems raised in the above background technology. UTILITY MODEL CONTENT

[0035] As shown in the attached diagram of the instruction manual. Figures 1-4 As shown, the entire device is first fixed at the mounting point by driving the mounting bolts 22 into the mounting plate 20. Activated carbon powder is placed on the first mesh 7 on the filter plate 4. The first mesh 7 is installed with the cover 9 by inserting the positioning pin 11 into the positioning hole 8. The activated carbon powder is held by the first mesh 7 and the second mesh 10. Then, the filter plate 4, along with the activated carbon powder, is slid into the sliding cavity 2 by pulling the handle 6. During the sliding process, the sliding block 5 slides into the sliding groove 3. Finally, the dust covers on the exhaust ports on both sides of the housing 1 are removed. 14. Then, the biogas is introduced into the shell 1 from the exhaust port on one side of the shell 1 and discharged from the exhaust port on the other side of the shell 1. During the process of biogas passing through, it passes through the second filter screen 13 and the first filter screen 12 in sequence to filter out particulate matter and dust impurities mixed in the biogas. The activated carbon powder in the filter plate 4 performs odor adsorption and purification of biogas. After the activated carbon powder has been working for a period of time, the filter plate 4 is slid off the shell 1 by pulling the handle 6. The activated carbon powder is poured out and replaced with new activated carbon powder by pulling out the positioning hole 8 through the positioning column 11.
