Description

Technical Field

[0001] This utility model relates to the field of biogas decarbonization and purification technology, specifically a novel biogas decarbonization and purification device. Background Technology

[0002] The absorption purification method utilizes the physicochemical absorption characteristics of organic amine solution and carbon dioxide. Specifically, under pressurized and ambient temperature conditions in the absorption tower, the solution reacts with carbon dioxide in the biogas to decarbonize and purify methane. The rich absorbent solution undergoes a reverse desorption reaction under reduced pressure and heating conditions in the regeneration tower, releasing high-purity carbon dioxide gas. Simultaneously, the rich absorbent solution is regenerated and gains the ability to reabsorb carbon dioxide, thus realizing a continuous decarbonization and purification process of biogas into methane in the absorption tower, and enabling the decarbonized solution to continuously absorb and regenerate in a cycle.

[0003] However, most of the filters in current biogas decarbonization and purification equipment are installed inside the tank, making it impossible for people to replace and clean them, thus affecting the biogas decarbonization and purification effect. Therefore, those skilled in the art have provided a new biogas decarbonization and purification device to solve the problems mentioned in the background art. Utility Model Content

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-5In this embodiment of the utility model, a novel biogas decarbonization and purification device includes a base 1, a biogas decarbonization and purification component 2, and a biogas filtration component 3. The biogas decarbonization and purification component 2 includes multiple biogas decarbonization and purification tanks 201, the outer surface of each biogas decarbonization and purification tank 201 being connected to the base 1. The biogas filtration component 3 includes a biogas filter frame 301, the outer surface of which is connected to the base 1. A booster pump 4 is installed on the upper surface of the base 1, which enables the device to achieve better decarbonization and purification of biogas. This solves the problem mentioned in the background art that most of the filters in current biogas decarbonization and purification devices are installed inside the tank, making it impossible for people to replace and clean them, thus affecting the biogas decarbonization and purification effect.

[0025] Each biogas decarbonization and purification tank 201 has a sealing ring 202 installed on its upper surface, and a cover plate 203 is installed on the upper surface of each biogas decarbonization and purification tank 201 by multiple screws. The outer surface of each group of biogas decarbonization and purification tanks 201 is connected to a gas guide pipe 204. A partition plate 207 is installed on the bottom surface of each cover plate 203. An exhaust pipe 205 is connected to the outer surface of one of the biogas decarbonization and purification tanks 201. A first valve 206 is installed on the outer surface of the exhaust pipe 205. The output end of the booster pump 4 is connected to an outlet pipe 6. The end of the outlet pipe 6 away from the booster pump 4 is connected to one of the biogas decarbonization and purification tanks 201. The input end of the booster pump 4 is connected to an inlet pipe 5. The end of the inlet pipe 5 away from the booster pump 4 is connected to the biogas filter frame 301. This can improve the decarbonization and purification effect of the equipment on biogas, thereby greatly increasing the practicality of the equipment.

[0026] The inner wall of the biogas filter frame 301 has two annular grooves 302. A first filter screen 303 is slidably connected inside one annular groove 302, and a second filter screen 304 is slidably connected inside the other annular groove 302. Sealing gaskets 305 are installed on the outer surfaces of the first filter screen 303 and the second filter screen 304. Mounting plates 306 are installed on the outer surfaces of the two sealing gaskets 305. The two mounting plates 306 are connected to the biogas filter frame 301 by screws. Handles 307 are installed on the outer surfaces of the two mounting plates 306. An air intake pipe 308 is connected to the outer surface of the biogas filter frame 301. A second valve 309 is installed on the outer surface of the air intake pipe 308. This not only enables the equipment to perform dual filtration of biogas, but also allows people to replace or clean the first filter screen 303 and the second filter screen 304.

[0027] The working principle of this utility model is as follows: First, the air inlet pipe 5 and the exhaust pipe 205 can be connected to the biogas transmission pipe and the collection pipe, respectively. Then, the neutralization solution can be injected into the biogas decarbonization and purification tank 201, and the cover plate 203 can be installed with screws. The sealing ring 202 and the sealing gasket 305 can prevent gas leakage. Then, the booster pump 4 can be started. The booster pump 4 can adsorb biogas into the biogas decarbonization and purification tank 201. The first filter screen 303 and the second filter screen 304 can filter impurities in the biogas. As the booster pump 4 continues to pressurize, the biogas can be neutralized with the neutralization solution inside the multiple biogas decarbonization and purification tanks 201 to complete the decarbonization and purification of the biogas.
