Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a particulate interceptor for waste gas treatment. Background Technology

[0002] When treating waste gas containing particulate pollutants, filtration is generally required to reduce the concentration of particulate pollutants. Waste gas is typically delivered to the treatment equipment via pipelines. To improve treatment efficiency, particulate interceptors can be added to the pipelines. These interceptors usually consist of a housing and a filter medium inside the housing. The filter medium can be a filter plate, which may have a porous structure. Particles are trapped within the porous structure of the filter plate, thus reducing the particulate content in the waste gas. Filter plates usually need to be replaced periodically. However, if the particulate content in the waste gas is unstable, errors may occur, such as replacing the filter too early or too late. Existing technology incorporates a transparent viewing window on the housing to observe the filter plate's condition, thereby preventing such errors. However, in actual filtration, the blockage on the filter plate usually occurs in the center, while the outer edge may still have some filtration effect. That is, there may be a situation where the center is severely blocked while the outer edge is normal. In this case, the decision to replace the filter plate may be made by observation, which may result in the filter plate being wasted. (If the condition of the outer edge is observed, the filter plate may be completely blocked before replacement, which will hinder normal filtration and affect the overall waste gas treatment efficiency.) Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a particulate interceptor for waste gas treatment, which solves the problem that existing technologies may lead to the waste of filter plates through observation.

[0004] According to an embodiment of this utility model, a particulate interceptor for waste gas treatment includes a housing, with an inlet pipe and an outlet pipe fixedly connected to opposite sides of the housing, and an inlet and outlet provided on the top surface of the housing. Inside the housing, a first clamping plate and a second clamping plate are fixedly connected below the inlet pipe and the outlet pipe, respectively, with the first clamping plate and the second clamping plate facing each other and a gap between them. It also includes a filter plate, with an upper sealing plate fixedly connected to the upper end of the filter plate that can engage with the inlet and outlet, and the lower end extending through the gap to below the first clamping plate and engaging with the inner bottom of the housing. The housing is also provided with a transparent window located below the first clamping plate, and the first clamping plate and the second clamping plate are respectively provided with a plurality of first through holes and a plurality of second through holes. The filter plate in this solution consists of two parts, one above and one below the first and second clamping plates. The upper part filters first. When severe blockage occurs, exhaust gas will partially flow downwards through the first through-hole, then through the lower part for filtration, and finally through the second through-hole into the exhaust pipe. This allows the filtration status of the lower part to be observed through a transparent window. When the lower part of the filter plate begins to become blocked, it indicates that the upper part is completely blocked, and the lower part has reached the point where it needs to be replaced. Therefore, the entire filter plate needs to be replaced, maximizing the utilization of the filter plate, avoiding waste, and ensuring smooth normal filtration. This solves the problem in existing technologies where observation may lead to wasted filter plates.

[0005] Furthermore, a slot is recessed at the bottom of the outer casing, the lower end of the filter plate engages with the slot, and a lower sealing plate can be detachably connected to the bottom of the slot.

[0006] Furthermore, a cover plate can be detachably connected to the inlet and outlet, and the cover plate and the upper sealing plate are fixedly connected by a connecting block.

[0007] Furthermore, the two ends of the upper sealing plate are bent upward to form a pair of first abutting parts, and the two first abutting parts slide in contact with the inner walls of the inlet and outlet respectively.

[0008] Furthermore, the ends of the first and second plates facing each other are bent downward to form a pair of second abutment portions, and a pair of abutment plates are fixedly provided on the filter plate, which respectively slide in contact with the two second abutment portions.

[0009] Furthermore, the filter plate includes an outer frame and a porous mesh fixed inside the outer frame. The lower end of the outer frame is engaged with a slot, and the upper end is fixedly connected to the upper sealing plate.

[0010] Furthermore, both ends of the abutment are fixedly connected to the outer frame.

[0011] Furthermore, the intake pipe and exhaust pipe are each fixedly connected with a connecting ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The first and second clamping plates provide a fixed foundation for the filter plate, and also divide it into upper and lower parts. By observing the filtration status of the lower part, when the lower part of the filter plate begins to become clogged, it indicates that the upper part is completely clogged and the lower part has reached the point where it needs to be replaced. Therefore, the entire filter plate needs to be replaced, which maximizes the utilization of the filter plate, avoids waste, and ensures smooth filtration. This solves the problem in the prior art where observing the filter plate may lead to its waste. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In an exemplary implementation, such as Figure 1-3As shown, this embodiment provides a particulate interceptor for waste gas treatment, which includes a housing 1. An inlet pipe 2 and an outlet pipe 3 are fixedly connected to opposite sides of the housing 1. The inlet pipe 2 and outlet pipe 3 can be installed on a pipe 4 via connecting rings 5 ​​fixed to them. Waste gas in the pipe 4 is introduced into the housing 1 through the inlet pipe 2 and exited from the housing 1 through the outlet pipe 3 into the subsequent pipe 4. An inlet / outlet 6 is provided on the top surface of the housing 1. A first retaining plate 7 and a second retaining plate 8 are fixedly connected inside the housing 1, located below the inlet pipe 2 and outlet pipe 3 respectively. Plates 8 are positioned opposite each other with a gap between them; the particulate interceptor also includes a filter plate 9, which includes an outer frame 10 and a porous mesh 11 fixed inside the outer frame 10. The outer frame 10 divides the interior of the housing into left and right parts. Exhaust gas needs to pass through the porous mesh 11 from one side to the other side. The porous mesh 11 is similar to the porous structure in the prior art. The porous mesh 11 intercepts particles, thereby achieving the filtering effect. The lower end of the outer frame 10 is snapped into the bottom of the outer shell 1, and the upper end is fixedly connected to an upper sealing plate 12 that can snap into the inlet / outlet 6. The outer shell 1 is also provided with A transparent window 13 is provided below the first card plate 7. The first card plate 7 and the second card plate 8 are respectively provided with a number of first through holes 14 and a number of second through holes 15. The first card plate 7 and the second card plate 8 can divide the filter plate 9 into an upper part and a lower part. The filtration status of the lower part can be observed through the transparent window 13. In actual filtration, the exhaust gas introduced from the air inlet pipe 2 will first pass through the upper part for filtration. When the upper part is severely blocked, some exhaust gas will pass down through the first through hole 14 on the first card plate 7, and then pass through the lower part for filtration, and then enter the air outlet pipe through the second through hole 15 on the second card plate 8 (the other part is filtered through the upper part that is not completely blocked). When the lower part is observed to start to block, it means that the upper part has been completely blocked after a period of use, and the lower part has reached the point where it needs to be replaced. Therefore, the entire filter plate 9 needs to be replaced. The filter plate 9 is utilized to a greater extent, avoiding waste, and ensuring smooth normal filtration. This solves the problem in the prior art where the filter plate 9 may be wasted by observation.

[0022] In further proposals, such as Figure 1 , 2 As shown, a slot 16 is recessed at the bottom of the outer casing 1, and the lower end of the outer frame 10 is engaged with the slot 16. The bottom of the slot 16 can also be detachably connected to a lower sealing plate 17. In this way, after the filter plate 9 is removed, the lower sealing plate 17 can be opened to assist in cleaning the inside of the outer casing 1, and it can also be used in conjunction with the inlet and outlet 6 for cleaning. The lower sealing plate 17 can be detachably connected by bolts 18.

[0023] In further proposals, such as Figure 1 , 3As shown, a cover plate 19 can be detachably connected to the inlet / outlet 6. The cover plate 19 and the upper sealing plate 12 are fixedly connected by a connecting block 20. The two ends of the upper sealing plate 12 are bent upward to form a pair of first abutting parts 21. The two first abutting parts 21 slide in contact with the inner wall of the inlet / outlet 6 respectively. The upper sealing plate 12 can be detachably connected by bolts 18. The upper sealing plate 12 and the first abutting parts 21 thereon play a better sealing role and prevent exhaust gas from leaking out through the air inlet.

[0024] In further detail, such as Figure 1 , 2 As shown, the ends of the first card plate 7 and the second card plate 8 facing each other are bent downward to form a pair of second abutment portions 22. A pair of abutment plates 23 are fixedly provided on the filter plate 9, which slide in contact with the two second abutment portions 22 respectively. At the same time, the two ends of the abutment plates 23 are fixedly connected to the outer frame 10 respectively. The cooperation between the abutment plates 23 and the second abutment portions 22 prevents particles from passing through between the first card plate 7, the second card plate 8 and the filter plate 9, and also avoids the first card plate 7 and the second card plate 8 from causing greater damage to the porous mesh 11 of the filter plate 9.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
