High-efficiency filter packing frame for exhaust gas treatment unit

Abstract

This utility model discloses a high-efficiency filter media holder for an exhaust gas treatment unit. When the exhaust gas enters the tower, the nozzle sprays external treatment liquid onto the filter media above the fixed frame, first movable frame, and second movable frame for thorough contact treatment. During operation, the adjustment component precisely adjusts the height of the first and second movable frames based on the real-time exhaust gas flow rate, thereby changing the spacing between the filter media layers. When the exhaust gas flow rate increases, the spacing between the filter media layers is appropriately increased to reduce the exhaust gas flow resistance, allowing the exhaust gas to pass through each filter media layer evenly and smoothly. This increases the contact area and contact time between the exhaust gas and the filter media, ensuring that pollutants are fully adsorbed and decomposed, significantly improving the exhaust gas treatment efficiency. Conversely, when the exhaust gas flow rate decreases, the spacing between the filter media layers is decreased to enhance the interaction between the exhaust gas and the filter media, also ensuring a high-efficiency treatment effect.

Description

Technical Field

[0001] This utility model relates to the technical field of high-efficiency filter media holders for waste gas treatment units, specifically a high-efficiency filter media holder for waste gas treatment units. Background Technology

[0002] In today's increasingly integrated industrial production and environmental protection landscape, waste gas treatment has become an indispensable and crucial aspect for many industries. Waste gas often contains large amounts of particulate matter, harmful gases, and volatile organic compounds (VOCs), among other pollutants. Direct emission without effective treatment will severely harm the atmospheric environment, human health, and ecological balance. Therefore, efficient and reliable waste gas treatment equipment and technologies are key to ensuring environmental quality. In waste gas treatment units, the filter media frame, as a core component, plays a vital role in supporting the media and promoting sufficient contact between the waste gas and the media to achieve purification functions such as pollutant adsorption and decomposition. The structure and arrangement of the media layer directly affect the effectiveness and efficiency of waste gas treatment.

[0003] Most existing filter media holders adopt a fixed structure design, and the height between each layer of the filter media holder is not adjustable. In the actual waste gas treatment process, parameters such as the composition, flow rate, temperature, and pollutant concentration of waste gas are not constant, but will change significantly with the adjustment of production process, fluctuation of production load, and changes in environmental conditions. When waste gas parameters change, the fixed-spacing filter media layers may not be able to maintain the best waste gas treatment effect. Therefore, we propose a high-efficiency filter media holder device for waste gas treatment units to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency filter media holder for exhaust gas treatment units, so as to solve the problem of adjusting the spacing of the filter media holder when using the high-efficiency filter media holder for exhaust gas treatment units mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency filter packing frame for a waste gas treatment unit, comprising a tower body;

[0006] The tower body is equipped with a fixed frame at the upper end, a first movable frame is provided below the fixed frame inside the tower body, a second movable frame is provided below the first movable frame inside the tower body, a fixed rod is provided inside the tower body, and a fixed sleeve is provided at the center of the fixed frame, the first movable frame and the second movable frame. The tower body is equipped with a spacing adjustment component and a liquid spraying component.

[0007] The spacing adjustment assembly includes a first lead screw, a first connecting block, a second lead screw, and a second connecting block. First sliding grooves are provided on the left and right sides inside the tower body. First connecting blocks are slidably installed inside both sets of first sliding grooves. A first lead screw is rotatably installed inside the left first sliding groove. The first lead screw is threadedly connected to the first connecting block on the same side.

The two sets of second connecting blocks are respectively connected to both sides of a first fixed frame.

[0008] As a preferred technical solution of this utility model, the spraying assembly includes a first fixed pipe, a delivery pipe and a nozzle. The first fixed pipe is provided above both the internal fixed frame and the first movable frame of the tower body. The first fixed pipe is connected to the fixed rod through the pipe. Multiple sets of delivery pipes are provided on both sides of the two sets of first fixed pipes. Multiple sets of nozzles are provided below the multiple sets of delivery pipes.

[0009] As a preferred embodiment of this utility model, the fixed rod is provided with an opening, a telescopic hose is provided inside the opening, a water supply pipe is provided at the top of the telescopic hose, the water supply pipe passes through the fixed rod and is connected to the outside, and a second fixed pipe is provided at the bottom of the telescopic hose.

[0010] As a preferred embodiment of this utility model, the upper end of the second fixed tube is connected to the bottom end of the first movable frame, and multiple sets of infusion tubes are provided on both sides of the second fixed tube, with multiple sets of nozzles provided below each set of infusion tubes.

[0011] As a preferred embodiment of this utility model, the fixing sleeve at the center of the fixing frame is fixedly connected to the fixing rod, and the fixing sleeves of the first and second movable frames are slidably connected to the fixing rod.

[0013] As a preferred embodiment of this utility model, two sets of connecting sleeves are provided on both sides of the second fixing rod, and the top of each set of connecting sleeves is connected to the bottom of the first movable frame.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: When the waste gas treatment unit uses a high-efficiency filter packing frame, after the waste gas enters the tower body, the nozzle sprays the external treatment liquid out to fully contact the packing material above the fixed frame, the first moving frame, and the second moving frame. During use, the adjustment component precisely adjusts the height of the first and second moving frames below according to the real-time waste gas flow rate, thereby changing the packing layer spacing. When the waste gas flow rate increases, the packing layer spacing is appropriately increased to reduce the waste gas flow resistance, allowing the waste gas to pass through each packing layer evenly and smoothly, increasing the contact area and contact time between the waste gas and the packing material, ensuring that pollutants are fully adsorbed and decomposed, and significantly improving the waste gas treatment efficiency. Conversely, when the waste gas flow rate decreases, the packing layer spacing is decreased to enhance the interaction between the waste gas and the packing material, which also ensures a high-efficiency treatment effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a high-efficiency filter packing frame for an exhaust gas treatment unit, comprising a tower body 1, a fixed frame 2 at the upper end of the tower body 1, a first movable frame 3 below the fixed frame 2 inside the tower body 1, a second movable frame 4 below the first movable frame 3 inside the tower body 1, a fixed rod 5 inside the tower body 1, and fixed sleeves 6 at the center positions of the fixed frame 2, the first movable frame 3, and the second movable frame 4. A spacing adjustment assembly 7 is provided inside the tower body 1, and a liquid spraying assembly 8 is provided inside the tower body 1. The liquid spraying assembly 8 includes a first fixed pipe 801, a liquid delivery pipe 802, and a nozzle 803. The body 1 has a first fixed tube 801 above the fixed frame 2 and the first movable frame 3. The first fixed tube 801 is connected to the fixed rod 5. Multiple sets of infusion tubes 802 are provided on both sides of the two sets of first fixed tubes 801. Multiple sets of nozzles 803 are provided below the multiple sets of infusion tubes 802. The fixed sleeve 6 at the center of the fixed frame 2 is fixedly connected to the fixed rod 5. The fixed sleeve 6 of the first movable frame 3 and the second movable frame 4 is slidably connected to the fixed rod 5. The fixed frame 2, the first movable frame 3 and the second movable frame 4 are all lined with filter plates 14. The filter plate 14 has a hole at the center that matches the size of the fixed sleeve 6.

[0024] During use, exhaust gas enters the tower body 1 through the inlet pipe on the left side. At the same time, external liquid for exhaust gas treatment enters the first fixed pipe 801. Then, multiple nozzles 803 below the liquid delivery pipes 802 on both sides of the first fixed pipe 801 spray the liquid evenly into the tower body 1. The liquid also enters the second fixed pipe 16 below through the water delivery pipe 13 at the top, and is then sprayed out through the nozzles 803 on the liquid delivery pipes 802 on both sides of the second fixed pipe 16. In this way, the liquid can fully cooperate with the packing material above the fixed frame 2, the first moving frame 3, and the second moving frame 4 to fully contact the gas, thereby achieving effective treatment of exhaust gas. The design of the fixed frame 2, the first moving frame 3, and the second moving frame 4 allows for multiple treatments, making the gas treatment more thorough.

[0025] The spacing adjustment assembly 7 includes a first lead screw 701, a first connecting block 702, a second lead screw 703, and a second connecting block 704. First sliding grooves 9 are provided on the left and right sides inside the tower body 1. First connecting blocks 702 are slidably mounted inside both sets of first sliding grooves 9. A first lead screw 701 is rotatably mounted inside the left first sliding groove 9. The first lead screw 701 is threadedly connected to the first connecting block 702 on the same side. The two sets of first connecting blocks 702 are respectively connected to both sides of the second fixing frame 2. Second sliding grooves 10 are provided on the front and rear sides inside the tower body 1. Second connecting blocks 704 are slidably mounted inside both sets of second sliding grooves 10. A second lead screw 703 is rotatably mounted inside the second sliding groove 10 on the front side of the tower body 1. 03 is threadedly connected to the second connecting block 704 on the same side. The two sets of second connecting blocks 704 are respectively connected to the two sides of the first fixed frame 2. The fixed rod 5 is provided with an opening 11. The opening 11 is provided with a telescopic hose 12. The top of the telescopic hose 12 is provided with a water supply pipe 13. The water supply pipe 13 passes through the fixed rod 5 and is connected to the outside. The bottom of the telescopic hose 12 is provided with a second fixed pipe 16. The upper end of the second fixed pipe 16 is connected to the bottom end of the first movable frame 3. Multiple sets of infusion pipes 802 are provided on both sides of the second fixed pipe 16. Multiple sets of nozzles 803 are provided below the multiple sets of infusion pipes 802. Two sets of connecting sleeves 15 are provided on both sides of the second fixed rod 5. The top of the multiple sets of connecting sleeves 15 is connected to the bottom end of the first movable frame 3.

[0026] During operation, when the exhaust gas flow rate changes, the time-distance adjustment component 7 begins to function. The motor drives the first lead screw 701 and the second lead screw 703 to rotate synchronously. At this time, the first lead screw 701 drives the first connecting block 702 to move in the first slide groove 9, causing the first connecting block 702 to drive the second moving frame 4 to move vertically inside the tower body 1. Simultaneously, the second lead screw 703 drives the second connecting block 704 to slide inside the second slide groove 10, allowing the height of the second moving frame 4 to be adjusted. At the same time, the second moving frame 4 drives the second fixed pipe 16 below to move up and down synchronously through the connecting sleeve 15. At this time, the second fixed pipe 16 drives the telescopic hose 12 to extend and retract synchronously, completing the independent adjustment of the height of the first moving frame 3 and the second moving frame 4. Since the height of the fixed frame 2 is fixed, the distance between the fixed frame 2, the first moving frame 3, and the second moving frame 4 can be adjusted to adapt to different exhaust gas flow rates and improve the treatment effect.

[0027] Working principle: When using the high-efficiency filter packing frame for the waste gas treatment unit, the waste gas enters the tower body 1 through the inlet pipe on the left side. At the same time, the liquid used for waste gas treatment enters the first fixed pipe 801. Subsequently, multiple nozzles 803 below the liquid delivery pipes 802 on both sides of the first fixed pipe 801 evenly spray the liquid into the tower body 1. The liquid also enters the second fixed pipe 16 below through the water delivery pipe 13 at the top, and is then sprayed out through the nozzles 803 on the liquid delivery pipes 802 on both sides of the second fixed pipe 16. In this way, the liquid can fully cooperate with the fixed frame 2. The packing material above the first moving frame 3 and the second moving frame 4 makes full contact with the gas, thereby achieving effective treatment of the waste gas. The design of the fixed frame 2, the first moving frame 3 and the second moving frame 4 allows for multiple treatments, making the gas treatment more thorough. During use, when the waste gas flow rate changes, the time interval adjustment component 7 starts to function, and the motor drives the first lead screw 701 and the second lead screw 703 to rotate synchronously. At this time, the first lead screw 701 drives the first connecting block 702 to move in the first slide groove 9, so that the first connecting block 702 drives the second moving frame 4 to move vertically inside the tower body 1. Simultaneously, the second lead screw 703 drives the second connecting block 704 to slide inside the second slide groove 10, allowing the second moving frame 4 to adjust its height. At the same time, the second moving frame 4 drives the second fixed pipe 16 below to move up and down synchronously through the connecting sleeve 15. At this time, the second fixed pipe 16 drives the telescopic hose 12 to extend and retract synchronously, completing the independent adjustment of the height of the first moving frame 3 and the second moving frame 4. Since the height of the fixed frame 2 is fixed, the distance between the fixed frame 2, the first moving frame 3 and the second moving frame 4 can be adjusted to adapt to different flow rates of exhaust gas and improve the treatment effect. The wastewater generated during the spraying process is drained and injected through the water pipe on the right side of the tower body 1, thus completing a series of operations. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
