Description

Technical Field

[0001] This utility model relates to the technical field of gas purification equipment, specifically to a gas treatment device using fiber filter media. Background Technology

[0002] With the rapid development of modern industry and the acceleration of urbanization, gaseous pollution problems such as industrial waste gas and domestic odors are becoming increasingly serious. These polluting gases contain a large number of harmful components, such as volatile organic compounds (VOCs), malodorous substances (such as hydrogen sulfide and ammonia), and various dust particles. They not only cause serious damage to the ecological environment and threaten the survival and reproduction of animals and plants, but also have a great negative impact on human health, such as causing respiratory diseases, allergic reactions, and damage to the nervous system.

[0003] To address the problem of gas pollution, various gas treatment technologies and equipment have emerged, among which fiber filter media gas treatment equipment has been widely used due to its high-efficiency filtration and adsorption performance. Fiber filter media, with its large specific surface area and abundant microporous structure, can effectively adsorb pollutants in gases, playing a positive role in air purification.

[0004] However, traditional fiber filter media gas treatment equipment has a significant limitation: the filter element has a short lifespan. During prolonged operation, the filter element continuously adsorbs pollutants, and its adsorption capacity gradually reaches saturation. Once saturated, the adsorption effect is greatly reduced, and it can no longer effectively remove harmful substances from the gas, at which point the filter element needs to be replaced. Frequent filter element replacement not only increases the operating costs of the equipment, including the purchase cost of the filter element, the labor costs during replacement, and the production losses caused by equipment downtime for filter element replacement, but also, if the discarded filter elements are not disposed of properly, can cause secondary pollution problems, placing an additional burden on the environment. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a fiber filter media gas treatment device. Through the design of a regeneration device, the filter element can be desorbed and regenerated, thereby extending the service life of the filter element, saving operating costs, and without reducing the adsorption effect.

[0006] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a fiber filter material gas treatment device includes a housing, a filter element disposed inside the housing, a regeneration device disposed above the housing, a storage chamber for regenerating liquid disposed below the housing, a circulation pipe disposed between the storage chamber and the regeneration device, the regeneration device includes a regeneration chamber, a through groove corresponding to the position of the filter element is disposed at the bottom of the regeneration chamber, a conveying pipe connected to the circulation pipe is disposed at the upper part of the regeneration chamber, and a distribution branch pipe corresponding to the position of the through groove is disposed on the side wall of the conveying pipe.

[0007] As a further improvement to the above technical solution:

[0008] The number of through channels, distribution branches, and filter elements are the same, and the centerlines of the three are located in the same plane.

[0009] The number of filter elements is multiple and they are evenly distributed along the length of the shell. Each filter element includes a support frame, and a filter layer is provided on the outside of the support frame.

[0010] The width of the channel gradually decreases from top to bottom, and the top of the filter element is provided with water-dividing protrusions that are coaxially distributed with the channel.

[0011] The conveying pipeline is located at the center line of the regeneration chamber, and the distribution branch pipes are located on both sides of the conveying pipeline. Each distribution branch pipe has a water-permeable hole on its lower surface.

[0012] The number of permeable holes is multiple and they are evenly distributed along the length of the distribution branch pipe. The diameter of the permeable holes gradually increases from the end closest to the conveying pipe outwards.

[0013] The storage compartment is equipped with a filtration section and a storage section, with a filter screen between the filtration section and the storage section. The side wall of the storage section is provided with a drain outlet for connecting to a circulation pipe.

[0014] The bottom of the storage unit is designed to be sloping, and the storage depth gradually increases from the end closest to the drain outlet outwards.

[0015] The beneficial effects of this utility model embodiment are as follows: The fiber filter material gas treatment equipment includes a shell, a filter element installed inside the shell, a regeneration device installed above the shell, and a storage chamber for recovering regenerated liquid installed below the shell. The storage chamber and the regeneration device are connected by a circulation pipe. The regeneration device includes a regeneration chamber, a through groove corresponding to the position of the filter element is opened at the bottom of the regeneration chamber, a conveying pipe connected to the circulation pipe is installed at the upper part of the regeneration chamber, and a distribution branch pipe corresponding to the position of the through groove is installed on the side wall of the conveying pipe. The regenerated liquid is distributed through the distribution branch pipe, thereby achieving uniform distribution of the regenerated liquid, ensuring that the regenerated liquid quickly penetrates the filter material when falling, and improving the desorption efficiency. The width of the through groove gradually decreases from top to bottom. The top of the filter element is provided with water-dividing protrusions distributed coaxially with the through groove. The water-dividing protrusions are arc-shaped and their height gradually decreases from the middle to both sides. They can guide the regenerated liquid to the filter material on both sides as the regenerated liquid falls, thereby improving the desorption and regeneration efficiency. Attached Figure Description

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] like Figure 1-5As shown, the fiber filter gas treatment equipment of this embodiment includes a housing 1, a filter element 2 installed inside the housing 1, a regeneration device installed above the housing 1, and a storage chamber 3 for recovering regenerated liquid installed below the housing 1. The storage chamber 3 is connected to the regeneration device through a circulation pipe 4. The regeneration device includes a regeneration chamber 5. A through groove 8 corresponding to the position of the filter element 2 is opened at the bottom of the regeneration chamber 5. A conveying pipe 6 connected to the circulation pipe 4 is installed at the upper part of the regeneration chamber 5. A distribution branch pipe 7 corresponding to the position of the through groove 8 is installed on the side wall of the conveying pipe 6. The regenerated liquid is distributed through the distribution branch pipe 7, thereby achieving uniform distribution of the regenerated liquid, ensuring that the regenerated liquid quickly permeates the filter material when falling, and improving the desorption efficiency.

[0024] The number of through channels 8, distribution branch pipes 7 and filter elements 2 are the same, and the centerlines of the three are located in the same plane.

[0025] There are multiple filter elements 2, which are evenly distributed along the length of the housing 1. Each filter element 2 includes a support frame 9. A filter layer 10 is provided on the outside of the support frame 9. The support frame 9 is a hollow cuboid frame. The filter layer 10 is made of fiber filter material covering the support frame 9. Each filter element has an opening at one end for gas flow. The openings of two adjacent filter elements 2 are in opposite directions. This ensures that the gas passes through at least two filter layers 10 when it passes through, which can improve the filtration effect of the gas.

[0026] The width of the channel 8 gradually decreases from top to bottom. The top of the filter element 2 is provided with water-dividing protrusions 11 that are coaxially distributed with the channel 8. The water-dividing protrusions 11 are arc-shaped and their height gradually decreases from the middle to both sides. As the regenerated liquid falls, it can guide the regenerated liquid to the filter media on both sides, thereby improving the efficiency of desorption and regeneration.

[0027] The conveying pipe 6 is located at the center line of the regeneration chamber 5, and the distribution branch pipes 7 are located on both sides of the conveying pipe 6. Each distribution branch pipe 7 has a water permeable hole 12 on its lower surface. There are multiple water permeable holes 12, which are evenly distributed along the length of the distribution branch pipe 7. The diameter of the water permeable hole 12 gradually increases from the end closest to the conveying pipe 6 outwards. This is to prevent the regenerated liquid from failing to flow to both ends of the through channel 8 when the conveying pressure is insufficient. The design of the distribution branch pipe 7 and the increasing diameter of the water permeable hole 12 are to ensure that the regenerated liquid can be evenly distributed and fall, thus ensuring the efficient desorption and regeneration operation.

[0028] The storage chamber 3 is equipped with a filtration section 13 and a storage section 14, which are separated by a filter screen 15. The storage section 14 has a drain outlet 16 for connecting to the circulation pipe 4 on its side wall. The filter screen 15 is designed to filter the regenerated liquid and prevent impurities from entering and clogging the circulation pipe 4.

[0029] The bottom of the storage section 14 is designed to be inclined, and the storage depth gradually increases from the end near the drain outlet 16 outwards. The inclined bottom design can collect the regenerated liquid. During the collection process, the impurities that are not filtered by the filter screen 15 are guided to the end away from the drain outlet 16, ensuring that the circulation pipe 4 will not be blocked during the circulation of the regenerated liquid.
