Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a high-efficiency activated carbon filter cartridge. Background Art

[0002] Existing industrial organic waste gas usually uses activated carbon to adsorb harmful substances in the waste gas. However, during the adsorption process of activated carbon on waste gas, there will be a situation where the concentration of industrial waste gas pollutants is relatively high. At this time, the activated carbon near the intake pipe will quickly reach the adsorption limit, thus significantly reducing the adsorption performance. While the activated carbon far from the intake pipe still has a high adsorption capacity, in order to ensure the effectiveness of the entire adsorption device, maintenance and replacement are still required. However, it is very troublesome to replace the activated carbon filter element of the existing equipment, and multiple components need to be disassembled and assembled, which results in the entire device being unable to complete maintenance quickly. Therefore, a high-efficiency activated carbon filter cartridge is designed to solve the above problems. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing waste gas purification technology, the purpose of the utility model is to provide a high-efficiency activated carbon filter cartridge, which has the advantages of enabling uniform adsorption of activated carbon and facilitating maintenance.

[0004] To achieve the above purpose, a technical solution adopted by the utility model is: a high-efficiency activated carbon filter cartridge, including a cylinder body, a spiral guide plate, a filter element support, a cylinder cover, a blocking ring, and an activated carbon filter element. One end face center of the cylinder body has an air outlet pipe, the other end of the cylinder body has a maintenance and inspection port and an intake pipe. The maintenance and inspection port is arranged at the center of the cylinder body end face. The cylinder cover is detachably arranged at the maintenance and inspection port. The intake pipe is arranged radially on the cylinder body. The blocking ring is arranged on one side of the cylinder body corresponding to the intake pipe. A spiral guide plate is arranged on the inner wall of the cylinder body, and the spiral guide plate is used to guide the air flow of the intake pipe to the air outlet pipe. The filter element support is arranged at the center of the cylinder body, and the activated carbon filter element is detachably arranged in the filter element support;

[0005] Preferably, the outer edge of the spiral guide plate fits the outer edge of the activated carbon filter element to form a spiral cavity, and the spiral cavity is communicated with the intake pipe;

[0006] Preferably, the activated carbon filter element is a hollow cylinder, the middle through hole of the activated carbon filter element is communicated with the air outlet pipe, and the outside of the activated carbon filter element is communicated with the spiral cavity;

[0007] Preferably, the blocking ring is used to prevent the air flow of the intake pipe from directly impacting the activated carbon filter element, and the blocking ring forces the air flow of the intake pipe to pass through the spiral cavity;

[0008] Preferably, annular sealing rings are further provided on both end faces of the activated carbon filter element;

[0009] The beneficial effects of the utility model are: 1. Exhaust gas enters the cylinder from the intake pipe. Since a blocking ring is provided at one end of the intake pipe, the airflow in the intake pipe will not directly impact the activated carbon filter element. The airflow in the intake pipe is guided by the spiral guide plate and blows evenly to the outside of the activated carbon filter element, thereby preventing the activated carbon filter element from partially reaching the adsorption limit and failing to work; 2. The cylinder cover is removed through the maintenance and inspection port, the failed activated carbon filter element is pulled out from the maintenance and inspection port, and then a new activated carbon filter element is replaced. After the replacement is completed, the cylinder cover is reinstalled on the maintenance and inspection port, so that the maintenance and replacement of the activated carbon filter element can be completed quickly.

[0016] See also Figures 1 to 4 , the utility model embodiment includes:

[0017] An efficient activated carbon filter cartridge, comprising a cylinder body 1, a spiral guide plate 2, a filter element support 3, a cylinder cover 4, a blocking ring 5 and an activated carbon filter element 6. One end face center of the cylinder body 1 has an air outlet pipe 11, and the other end of the cylinder body 1 has a maintenance and inspection port 12 and an air inlet pipe 13. The maintenance and inspection port 12 is arranged at the center of the end face of the cylinder body 1. The cylinder cover 4 is detachably arranged at the maintenance and inspection port 12. The air inlet pipe 13 is arranged radially on the cylinder body 1. The blocking ring 5 is arranged inside the cylinder body 1 on one side corresponding to the air inlet pipe 13. The inner wall of the cylinder body 1 is provided with a spiral guide plate 2, and the spiral guide plate 2 is used to guide the air flow of the air inlet pipe 13 to the air outlet pipe 11. The filter element support 3 is arranged at the center of the cylinder body 1, and the activated carbon filter element 6 is detachably arranged inside the filter element support 3;

[0018] The outer edge of the spiral guide plate 2 fits the outer edge of the activated carbon filter element 6 to form a spiral cavity 7, and the spiral cavity 7 communicates with the air inlet pipe 13;

[0019] The activated carbon filter element 6 is a hollow cylinder. The central through hole in the middle of the activated carbon filter element 6 communicates with the air outlet pipe 11, and the outside of the activated carbon filter element 6 communicates with the spiral cavity 7;

[0020] The blocking ring 5 is used to prevent the air flow of the air inlet pipe 13 from directly impacting the activated carbon filter element 6, and the blocking ring 5 forces the air flow of the air inlet pipe 13 to pass through the spiral cavity 7;

[0021] Both end faces of the activated carbon filter element 6 also have annular sealing rings;

[0022] Through the above settings, in the actual working process, its specific working principle is as follows:

[0023] First, connect the air inlet pipe 13 to the exhaust gas suction end, and connect the air outlet pipe 11 to the exhaust end after the exhaust gas is adsorbed. Driven by an external fan, the exhaust gas enters the cylinder body 1 from the air inlet pipe 13. Since a blocking ring 5 is arranged at one end of the air inlet pipe 13, the air flow of the air inlet pipe 13 will not directly impact the activated carbon filter element 6. The air flow of the air inlet pipe 13 is guided by the spiral guide plate 2 and evenly blows to the outside of the activated carbon filter element 6, thereby preventing the local area of the activated carbon filter element 6 from reaching the adsorption limit and being unable to work;

[0024] When replacing the activated carbon filter element 6, remove the cylinder cover 4, then axially extract the failed activated carbon filter element 6 from the maintenance and inspection port 12, and then replace it with a new activated carbon filter element 6. After the replacement, reinstall the cylinder cover 4 on the maintenance and inspection port 12, so that the maintenance and replacement of the activated carbon filter element 6 can be quickly completed;

[0025] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
