Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a catalytic waste gas processor for waste gas treatment. Background Technology

[0002] During combustion in a catalytic combustion device, some non-combustible dust particles may be present in the exhaust gas, which can easily accumulate inside the combustion furnace and affect the combustion effect. Therefore, the exhaust gas needs to be filtered.

[0003] Among the relevant technologies, a search revealed that the exhaust gas catalytic combustion processor (announcement number CN213160087U) uses a limiting plate, a spring plate, a second spring, and a hook. During use, the filter plate is engaged with the cover by the placement groove on the front end of the filter plate. Then, the filter plate is aligned with the middle of the two limiting plates and pushed inward to make the filter plate contact the spring plate. At the same time, the second spring is compressed. Finally, the cover and the placement frame are fixed. The setting of the limiting plate fixes the direction of the filter plate and prevents the filter plate from tilting. The filter plate is used to filter the exhaust gas.

[0004] However, when using filter plates for filtration, the filter plates are easily clogged by dust particles after a period of use, requiring frequent cleaning. Otherwise, the problem of high resistance to exhaust gas flow may occur. When multiple filter plates are installed, they need to be replaced one by one, which is not convenient. Utility Model Content

[0005] The purpose of this invention is to provide a catalytic waste gas processor for waste gas treatment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a catalytic waste gas processor for waste gas treatment, comprising a water tank, wherein a plurality of support rods are provided inside the water tank, and a plurality of triangular slag collecting strips are connected to the support rods; the water in the water tank can collect most of the dust particles, and the triangular slag collecting strips can collect the floating dust particles.

[0007] The filter box is cylindrical and connected to the water tank. The filter box is rotatably equipped with a door. A tubular filter is installed inside the filter box. A dispersion cone is provided at the bottom of the filter box. The tubular filter can perform dual filtration of dust particles. The tubular filter performs secondary filtration of dust particles, which can prevent the tubular filter from clogging and extend the replacement cycle of the tubular filter.

[0008] A catalytic burner, which is connected to a filter box, processes the exhaust gas that has been filtered by a water tank and a tubular filter.

[0009] Furthermore, an air inlet pipe and an air outlet pipe are installed on the upper surface of the water tank, and the air outlet pipe is connected to the filter box. The air inlet pipe is inserted into the water tank and located above the dispersion cone. The dispersion cone can quickly disperse dust particles into the water, improving dust capture efficiency. An observation window is provided on the surface of the water tank to check whether the water needs to be changed.

[0010] Furthermore, the tubular filter is provided with a support rod in the middle, and the support rod is provided with a bracket to hold the tubular filter in place, so as to ensure that the tubular filter is not easily deformed, has a good sealing effect during long-term use, and prevents dust particles from entering the catalytic burner.

[0011] Furthermore, the inner wall of the filter box is provided with two sealing strips, one above the other, and the tubular filter is placed between the two sealing strips to reserve space for the flow of exhaust gas and to ensure that the tubular filter can fully perform its filtering function.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The exhaust gas is first introduced into the water tank, and the water is used to capture dust particles, reducing the content of dust particles in the exhaust gas. Opening the drain valve can quickly discharge water and dust particles, and opening the water supply valve can add water, making it more convenient to deal with dust particles.

[0014] (2) The tubular filter performs a second filtration of the exhaust gas, which can prevent a large number of dust particles from being filtered by the tubular filter, effectively extend the replacement cycle of the tubular filter, reduce downtime for maintenance, and ensure the continuous and stable operation of the filter box.

[0015] (3) The tubular filter, together with the filter box and sealing strip, can perform dual filtration of exhaust gas. When replacing the tubular filter, loosen the handle bolt and open the box door to directly remove the tubular filter for replacement. Replacement is convenient and operation is simple.

[0016] (4) The dispersion cone can diffuse the exhaust gas and dust particles to all parts of the water tank, giving full play to the water's ability to capture dust particles. As the dust particles rise with the bubbles, they are collected by the triangular slag collection strips, resulting in less dust particles in the exhaust gas discharged from the water tank and a better filtration effect.

Detailed Implementation

[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] Example:

[0024] Please see Figure 1-4 This utility model provides a technical solution: a catalytic waste gas processor for waste gas treatment, including a water tank 1. The water tank 1 is provided with a plurality of support rods 12. A plurality of triangular slag collecting strips 13 are connected to the support rods 12. When waste gas enters the water tank 1, dust particles are captured by the water. When the dust particles encased in air bubbles float to the surface, they hit the triangular slag collecting strips 13 and break. The triangular slag collecting strips 13 can prevent the dust particles from floating to the surface, thus giving full play to the water's ability to capture dust particles.

[0025] The filter box 7 is cylindrical and connected to the water tank 1. The filter box 7 is rotatably equipped with a door 8. The filter box 7 is equipped with a tubular filter 15. Dust particles in the exhaust gas are captured by water and then filtered by the tubular filter 15, which reduces the filtration intensity of the tubular filter 15, extends the cleaning cycle of the tubular filter 15, and thus reduces maintenance time. The tubular filter 15 can filter the exhaust gas twice. The tubular filter 15 has an integral structure for easy replacement. The bottom of the filter box 7 is equipped with a dispersion cone 11, which can make the exhaust gas diffuse into the water in 360 degrees.

[0026] The catalytic burner 10 is connected to the filter box 7. The catalytic burner 10 treats the exhaust gas filtered by the water tank 1 and the tubular filter 15. The catalytic burner 10 decomposes the exhaust gas into carbon dioxide and water, thereby achieving environmentally friendly emissions of the exhaust gas.

[0027] In this embodiment, as Figure 2As shown, an air inlet pipe 3 and an air outlet pipe 6 are installed on the upper surface of the water tank 1, and the air outlet pipe 6 is connected to the filter box 7. The air inlet pipe 3 is inserted into the water tank 1 and located above the dispersion cone 11. The air inlet pipe 3 has several thin tubes, which can diffuse the exhaust gas into the water more evenly.

[0028] In this embodiment, as Figure 1 As shown, the surface of the water tank 1 is provided with an observation window 2, which allows the user to check the turbidity of the water and determine whether the water needs to be changed.

[0029] In this embodiment, as Figure 1 and Figure 4 As shown, a screw plate 18 and a handle bolt 19 screwed to the screw plate 18 are installed on the filter box 7. The handle bolt 19 passes through the box door 8. By loosening the handle bolt 19 and separating it from the screw plate 18, the box door 8 can be opened, and the tubular filter 15 can be pulled out of the filter box 7 for replacement.

[0030] In this embodiment, as Figure 3 As shown, the tubular filter 15 has a support rod 16 in the middle, and a bracket 17 is provided on the support rod 16 to support the tubular filter 15. The bracket 17 can support the tubular filter 15, prevent the tubular filter 15 from deforming, and ensure that the tubular filter 15 is used normally and is more durable.

[0031] In this embodiment, as Figure 1 As shown, a fan 9 is installed between the filter box 7 and the catalytic burner 10. The fan 9 can actively supply exhaust gas to the catalytic burner 10 to ensure that the catalytic burner 10 is in a state of high-efficiency operation.

[0032] In this embodiment, as Figure 1 As shown, a water supply valve 4 is provided on the upper side of the water tank 1. Water can be added to the water tank 1 by opening the water supply valve 4. A drain valve 5 is installed on the lower surface of the water tank 1. Water and dust particles can be discharged by opening the drain valve 5, making it convenient and quick to clean the dust particles.

[0033] In this embodiment, as Figure 3 As shown, the inner wall of the filter box 7 is provided with two sealing strips 14, one above the other. The tubular filter 15 is placed between the two sealing strips 14. The two sealing strips 14 can block the flow of exhaust gas and ensure that the exhaust gas is filtered twice by the tubular filter 15.

[0034] Specifically, during use, exhaust gas containing dust particles enters water tank 1 through air inlet pipe 3. Dispersion cone 11 diffuses the exhaust gas and dust, water captures dust particles, and when the bubbles formed by the exhaust gas in the water float to the surface, they are broken by the multi-layer triangular slag collection strips 13. The dust particles in the bubbles are intercepted by the triangular slag collection strips 13, effectively reducing the amount of dust particles in the exhaust gas.

[0035] Exhaust gas enters filter box 7 from exhaust pipe 6. The exhaust gas first passes through tubular filter 15, where dust particles are filtered once. When the exhaust gas is discharged from tubular filter 15, the dust particles are filtered once more, thus achieving dual filtration of exhaust gas.

[0036] Fan 9 draws in exhaust gas and sends it into catalytic burner 10. Catalytic burner 10 uses a catalyst to reduce the temperature of the exhaust gas combustion, accelerates the oxidation and decomposition of the exhaust gas, and converts it into harmless carbon dioxide and water vapor.

[0037] The exhaust gas filtered by the tubular filter 15 is first filtered by water, which can reduce the filtration volume of the tubular filter 15 and extend the maintenance cycle and service life of the tubular filter 15.

[0038] When replacing the tubular filter 15, loosen the handle bolt 19 from the screw plate 18, then turn and open the box door 8 to pull the tubular filter 15 out of the filter box 7, thus replacing the tubular filter 15.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
