Description

Technical Field

[0001] This utility model belongs to the field of gas filtration technology, and in particular relates to a filtration device for waste acidic gases. Background Technology

[0002] Acidic gas is injected into the filter chamber and reacted and dissolved using a filter solution. A stirring mechanism agitates the solution, thus removing acid from the gas. However, as the gas flows upwards from the solution, it carries away a large amount of water vapor. This water vapor carried by the bubbles or gas needs to be removed before it can be released into the air. Existing filtration equipment lacks an optimal method for removing this water vapor, requiring multiple sets of water washing equipment to remove the cleaning solution and water vapor. This process is cumbersome and costly. Utility Model Content

[0003] The purpose of this invention is to provide a filtration device for waste acidic gases. Waste acidic gases are discharged into the bottom of the filter tank through an air inlet pipe assembly. The gas diffuses in the cleaning liquid and is absorbed by acidic substances. The discharged gas is then filtered through a water vapor filtration component to remove water vapor and further absorb acidic gases. This solves the problems of incomplete water washing of waste acidic gases, inability to remove volatilized water vapor, the need for other equipment to absorb water vapor, and high costs.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a filtration device for waste acidic gases, comprising a filter barrel, an air inlet pipe assembly, and a water vapor filtration component. An air inlet pipe assembly is inserted into one side wall of the filter barrel at its center, and a liquid inlet pipe is inserted into the other side wall of the filter barrel at its center. A drain pipe is located at the bottom of the filter barrel, and both the liquid inlet pipe and the drain pipe are equipped with manual valves. A barrel lid is placed on top of the filter barrel, and an exhaust pipe is located on the lid. A water vapor filtration component is inserted into the upper half of the filter barrel, and the top of the water vapor filtration component hangs on the bottom of the lid. The water vapor filtration component includes a water vapor filter cloth, a cloth clamping frame, and a connecting rod. The water vapor filter cloth is clamped within the cloth clamping frame, and multiple cloth clamping frames are connected by connecting rods.

[0006] The present invention is further configured such that the air intake pipe assembly includes a square pipe 2 and an exhaust round pipe, one end of the square pipe is sealed, and multiple exhaust round pipes are inserted into the bottom of the square pipe at the sealed end. The sealed end of the square pipe is inserted into the filter barrel, and the bottom ends of the multiple exhaust round pipes are inserted into the bottom of the filter barrel.

[0007] The present invention is further configured such that the cloth clamping frame includes a circular base frame and a circular clamping frame. The upper half of the inner side wall of the circular base frame is provided with a circular platform. The circular clamping frame is erected on the circular platform. The water vapor filter cloth is laid around the circular platform and clamped by the circular clamping frame. The circular platform is provided with a first bolt hole, and the circular clamping frame is provided with a second bolt hole. The first bolt hole and the second bolt hole are aligned and then fastened with bolts.

[0008] The present invention is further configured such that the circular clamping frame is provided with an upward arc-shaped beam, and a hook is provided at the bottom of the middle position of the upward arc-shaped beam, and the center position of the water vapor filter cloth is tied to the hook with a rope.

[0009] The present invention is further configured such that a plurality of mounting holes are evenly distributed around the circumference of the circular chassis frame, and the connecting rod is connected to the mounting holes on two adjacent circular chassis frames.

[0010] The present invention is further configured such that the number of water vapor filter cloths is 3-5, and no water vapor filter cloth is provided in the uppermost cloth clamping frame.

[0011] This utility model has the following beneficial effects:

[0012] This invention allows waste acidic gas to be evenly and dispersed into the bottom of the washing liquid through multiple exhaust pipes. The gas diffuses upward and is washed and adsorbed by the washing liquid. As the gas rises, the water vapor it carries passes through multiple layers of water vapor filter cloth. The water vapor adheres to the water vapor filter cloth, and the rising gas makes the water vapor filter cloth wet. This not only filters water vapor but also further adsorbs the small amount of acidic gas contained in the rising gas, resulting in better removal of acidic gas and lower water vapor content.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model is a filtration device for waste acidic gas, including a filter barrel 1, an air inlet pipe assembly, and a water vapor filtration component 4. The air inlet pipe assembly is inserted into one side wall of the middle position of the filter barrel 1, and a liquid inlet pipe 11 is inserted into the other side wall of the middle position of the filter barrel 1. A drain pipe 12 is provided at the bottom of the filter barrel 1. Both the liquid inlet pipe 11 and the drain pipe 12 are equipped with manual valves (or electric valves). The top of the filter barrel 1 is covered with a barrel cover 3, and an exhaust pipe 31 is provided on the barrel cover 3. The water vapor filtration component 4 is inserted into the upper half of the filter barrel 1. The top of the water vapor filtration component 4 is hung on the bottom of the barrel cover 3. The water vapor filtration component 4 includes a water vapor filter cloth 44, a cloth clamping frame, and a connecting rod 43. The water vapor filter cloth 44 is clamped in the cloth clamping frame, and multiple cloth clamping frames are connected by the connecting rod 43.

[0024] The gas enters the filter tank 1 through the inlet pipe assembly. The waste acidic gas is discharged to the bottom of the filter tank 1 (the liquid level in the filter tank 1 is less than half the height of the filter tank 1). The bubbles are absorbed by tumbling in the washing liquid. The bubbles carry some water vapor. When the gas passes through the water vapor filter assembly 4, it is blocked by the water vapor filter cloth 44. The gas passes through the water vapor filter cloth 44 and is discharged upwards. The water vapor adheres to the water vapor filter cloth 44, making it moist and enhancing its water vapor adsorption function. The water vapor accumulates on the water vapor filter cloth 44 and drips down, or drainage holes are provided on the cloth clamp (not shown, to be designed as needed). After the gas is discharged from the exhaust pipe 31, the water content is reduced, and it can be discharged directly.

[0025] Periodically drain half of the washing solution in filter tank 1 and replenish the other half with fresh washing solution to ensure that there is always washing solution available and the washing effect is maintained. Replace the washing solution promptly when the washing effect decreases.

[0026] The intake pipe assembly includes a square pipe 2 and an exhaust pipe 21. One end of the square pipe 2 is sealed, and multiple exhaust pipes 21 are inserted into the bottom of the square pipe 2 at the sealed end. The sealed end of the square pipe 2 is inserted into the filter barrel 1, and the bottom ends of the multiple exhaust pipes 21 are inserted into the bottom of the filter barrel 1.

[0027] The square tube 2 makes it easy to install the exhaust round pipe 21 on the same horizontal plane. Multiple exhaust round pipes 21 allow the bubbles to diffuse evenly and be absorbed by the washing liquid to remove acidic gases.

[0028] The fabric clamping frame includes a circular base frame 42 and a circular clamping frame 41. The upper half of the inner side wall of the circular base frame 42 is provided with a circular platform 421. The circular clamping frame 41 is erected on the circular platform 421. The water vapor filter cloth 44 is laid around the circular platform 421 and clamped by the circular clamping frame 41. The circular platform 421 is provided with a first bolt hole 422, and the circular clamping frame 41 is provided with a second bolt hole 411. The first bolt hole 422 and the second bolt hole 411 are aligned and then fastened with bolts.

[0029] First, lay the water vapor filter cloth 44 on the circular platform 421, then press the circular clamping frame 41 down onto the circular platform 421, and screw the bolts into the first bolt hole 422 and the second bolt hole 411 to fix it. The gap between the circular base frame 42 and the inner wall of the filter barrel 1 is small, so it can only be pulled out, and the amount of gas flowing through the gap is small.

[0030] The circular clamping frame 41 is provided with an upward arc-shaped beam 412, and a hook 413 is provided at the bottom of the middle position of the upward arc-shaped beam 412. The center position of the water vapor filter cloth 44 is tied to the hook 413 with a rope.

[0031] The upper arc-shaped beam 412 pulls the water vapor filter cloth 44 upward into an inverted cone shape. This facilitates the flow of water droplets formed by water vapor to all sides, where they gather and drip off at the edges.

[0032] The circular chassis frame 42 is provided with a plurality of mounting holes 423 evenly distributed around its circumference, and the connecting rod 43 is connected to the mounting holes 423 on two adjacent circular chassis frames 42.

[0033] The two ends of the connecting rod 43 are inserted into the mounting holes 423 to complete the fixation, or the middle of the connecting rod 43 can be rotated, and the two ends of the connecting rod 43 are spirally inserted into the mounting holes 423.

[0034] The number of water vapor filter cloths 44 is 3-5, with no water vapor filter cloth 44 placed in the uppermost cloth clamping frame. Multi-layer filtration can remove most of the water vapor and also adsorb residual acidic gases, allowing the filtered gases to be directly discharged into the air. The water vapor filter cloths 44 are woven from PTFE (polytetrafluoroethylene), polypropylene, glass fiber, etc., and are acid-resistant.
