Description

Technical Field

[0001] The invention relates to the technical field of biogas purification and treatment, in particular to biogas purification and treatment equipment. Background Art

[0002] Biogas is a mixed gas, the main component of which is methane, followed by carbon dioxide, hydrogen sulfide, saturated water vapor, high carbon hydrocarbons, etc.; sometimes it also contains impurities such as carbon monoxide, nitrogen, helium, hydrogen, siloxanes, halogenated hydrocarbons and solid particles. Since biogas contains the above impurities and the flow, pressure, temperature, concentration, etc. of biogas are very unstable, direct use for gas-fired power generation is bound to cause equipment corrosion, grinding and other problems of the gas-fired generator, thereby seriously shortening the life of the gas-fired generator. Therefore, before use, the biogas must be purified to solve the above problems.

[0003] The existing equipment for biogas purification cannot filter the impurities of the introduced biogas in advance, which causes the impurities to affect the permeability of the subsequent purification components, thereby affecting the purification work of the equipment. In addition, since the purification equipment cannot change the direction of the gas flow inside it, the contact mode between the gas and the catalyst is relatively single, which affects the catalytic efficiency of the catalyst. For this reason, we propose a biogas purification equipment. Summary of the invention

[0004] The object of the present invention is to provide a biogas purification and treatment device to solve the problem that the existing biogas purification and treatment device proposed in the above background technology cannot filter the impurities of the introduced biogas in advance, so that the impurities affect the permeability of the subsequent purification components, thereby affecting the purification work of the equipment; and since the purification equipment cannot change the direction of the gas flow inside it, the contact mode between the gas and the catalyst is relatively single, thereby affecting the catalytic efficiency of the catalyst.

[0006] Preferably, the filter chamber is connected to the purification chamber through a connecting pipe, and the mesh diameter inside the first filter plate is larger than the mesh diameter inside the second filter plate, and the diameter of the filter holes decreases sequentially from bottom to top.

[0007] Preferably, the filter element is configured as a hollow structure, and the center of the filter element and the center of the connecting plate are on the same straight line, and the filter element forms a transparent structure with the corrugated plate through the through hole.

[0008] Preferably, the corrugated plate is connected to the hollow column and the filter element through the through hole, and the corrugated plate and the hollow column are arranged inside the filter chamber in a cross-shaped structure.

[0009] Preferably, the inner wall surface of the catalyst is tightly fitted with the inner and outer wall surfaces of the hollow column, and the hollow column forms a transparent structure with the filter chamber through the air outlet.

[0010] Preferably, the sizes of the groove and the protrusion match each other, and the connecting plate forms a detachable structure with the shell through the cooperation between the groove and the protrusion.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 2.

Therefore, through the cooperation between the filter chamber 2 and the purification chamber 8, the biogas treatment can process the gas in an orderly manner, thereby effectively improving the working efficiency of the treatment equipment. A first filter plate 4 is fixed inside the filter chamber 2, and a second filter plate 5 is arranged just above the first filter plate 4. The second filter plate 5 is provided with filter holes 6 inside. The top of the filter chamber 2 is connected to a connecting pipe 7, and the top surface of the connecting pipe 7 is connected to the purification chamber 8;

[0021] A connecting plate 9 is fixed inside the purification chamber 8, and a filter element 10 is embedded in the middle of the connecting plate 9. The filter element 10 is set to a hollow structure, and the center of the filter element 10 is on the same straight line as the center of the connecting plate 9. The filter element 10 forms a transparent structure with the corrugated plate 11 through the through hole 16. The position setting between the filter element 10 and the connecting plate 9 allows it to evenly transmit the filtered gas through the through hole 16 to between the filter element 10 and the connecting plate 9, thereby avoiding the influence of the purification efficiency of the purification chamber 8 due to the large amount of gas gathering in a certain place. The filter element 10 with a hollow and mesh structure can transmit the gas while filtering the residual impurity particles inside it, thereby providing convenience for the gas purification work. Therefore, through the mutual cooperation between it and the filter chamber 2, the processing equipment can be divided into Impurities are filtered, thereby avoiding the clogging of the purification mesh inside the purification chamber 8 due to the large number of impurity particles inside the above-mentioned gas, thereby affecting its purification efficiency. The corrugated plate 11 is arranged between the filter element 10 and the connecting plate 9. The corrugated plate 11 is connected with the hollow column 12 and the filter element 10 through the through hole 16, and the corrugated plate 11 and the hollow column 12 are arranged in a cross-shaped structure inside the filter chamber 2. The shape of the corrugated plate 11 and the arrangement of the through holes 16 inside it can change the direction of the gas flow inside the purification chamber 8, and the through holes 16 are staggered and arranged in the same manner, which effectively prolongs the time that the gas stays in the purification chamber 8, so that it can fully catalytically treat the toxic gas inside the biogas, thereby effectively improving the purification efficiency of the biogas treatment equipment;

The connecting plate 9 forms a detachable structure with the purification chamber 8 through the cooperation of the groove 17 and the protrusion 18. The setting of the size between the groove 17 and the protrusion 18 makes it possible to position the connecting plate 9 and the purification chamber 8, and fix them by bolts, thereby avoiding the device being affected by external factors due to the large connection gap between them, resulting in misalignment between them, thereby damaging the connection component assembly between the purification chamber 8 and the filter chamber 2, and causing wear on the contact surface between the purification chamber 8 and the connecting plate 9, thereby shortening its service life. The combination between the groove 17 and the protrusion 18 can facilitate the disassembly and assembly work between the connecting plate 9 and the purification chamber 8, thereby facilitating the processing work of the purification equipment, thereby improving its flexibility.
