Description

Technical Field

[0001] This utility model relates to the field of flue gas emission detection technology, and specifically to a flue gas filtration device for flue gas emission detection. Background Technology

[0002] Flue gas is generated in every step of the processing in various fields. Before being emitted, the flue gas needs to be tested and filtered to ensure that it meets the emission standards.

[0003] In existing flue gas filtration technologies, the presence of a large amount of dust within the flue gas causes dust particles to easily clog the filter components over time, reducing their permeability and consequently decreasing the flue gas filtration efficiency.

[0004] To address the aforementioned technical issues, CN222239451U discloses a boiler flue gas filtration device. By installing nozzles, when filtering boiler flue gas, the inlet pipe is opened, allowing the flue gas to enter the filter box, prompting the filter blocks to filter the flue gas. At this time, the nozzles are opened, allowing water to be rapidly sprayed onto the top of the filter blocks, thus flushing away the dust particles inside the filter blocks and discharging them into the water tank. This achieves a cleaning and cooling effect on the filter blocks, preventing blockage caused by excessive dust inside the filter blocks, which hinders flue gas flow. This improves the stability of the flue gas filtration device during long-term operation.

[0005] The existing technology also has the following shortcomings: due to long-term use, the filter element is prone to clogging or reduced filtration efficiency, so it needs to be replaced. However, the replacement steps in the existing technology are cumbersome and not conducive to quick disassembly and assembly of the filter element. Utility Model Content

[0027] 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.

[0028] This utility model provides a flue gas filtration device for flue gas emission detection, including a housing 1;

[0029] The inner cavity of the outer shell 1 is provided with a filter mechanism 2 for flue gas treatment. The filter mechanism 2 and one end of the outer shell 1 are provided with a mounting mechanism 3 for easy disassembly and assembly. The top of the outer shell 1 is connected to an exhaust pipe 5. One end of the inner cavity of the outer shell 1 is provided with a support sleeve 4.

[0030] The filter mechanism 2 includes a flue gas treatment component and a connecting component. The flue gas treatment component is disposed inside the housing 1, and the connecting component is disposed on the inner side wall of the housing 1.

[0031] The gas filtration process is achieved through the cooperation of the flue gas treatment component and the connecting component, and the filter mechanism 2 can be connected to the outer casing 1.

[0032] The installation mechanism 3 includes an insertion component, a support component, an elastic component, and an adapter component. The insertion component is located at one end of the flue gas treatment component, the support component is located at one end of the housing 1, the elastic component is located inside the support component, and the adapter component is located outside the support component.

[0033] The cooperation between the insertion component, support component, elastic component and adapter component facilitates end sealing and connection operations, while its operation is simple and convenient, which is conducive to subsequent disassembly and assembly operations.

[0034] Preferred;

[0035] like Figure 5 As shown, the flue gas treatment assembly includes a flue gas filter body 21. The air inlet end of the flue gas filter body 21 is inserted into the inside of the support sleeve 4. A first connecting ring 22 is fixedly installed on one end of the outer side of the flue gas filter body 21, which realizes the effect of direct filtration of gas and facilitates installation by means of threaded connection.

[0036] like Figure 3 As shown, the connecting assembly includes a second connecting ring 23, which is fixedly installed on the inner wall of the housing 1. A retaining ring 25 is also fixedly installed on the inner wall of the housing 1. The second connecting ring 23 and the first connecting ring 22 are threadedly connected. A baffle 24 is fixedly installed at one end of the first connecting ring 22 to facilitate support during operation, and also to limit movement and connect with external connecting parts during installation.

[0037] After the following operations are completed, the flue gas filter body 21 can be inserted into the inside of the outer shell 1. At the same time, rotate the flue gas filter body 21 to drive the first connecting ring 22 to rotate synchronously, so that the first connecting ring 22 and the second connecting ring 23 are threadedly connected until the first connecting ring 22 contacts the retaining ring 25. At this time, the air inlet end of the flue gas filter body 21 is inserted into the inside of the support sleeve 4.

[0038] The flue gas then enters through the inlet and is filtered. The treated gas is located between the flue gas filter body 21 and the outer shell 1, and is discharged to the outside through the exhaust pipe 5. The exhaust pipe 5 can be connected to an external pipe for directional discharge.

[0039] It is worth explaining;

[0040] like Figure 6 As shown, the insertion component includes a connector 31, which is fixedly installed on one side of the baffle 24. A protrusion 33 is fixedly installed on one end of the connector 31, and connector blocks 32 are fixedly installed on both sides of the connector 31, which can realize the insertion and removal limit operation to facilitate subsequent connection.

[0041] like Figure 6 As shown, the support assembly includes a connecting pipe 37, which is snapped onto the outside of the connecting block 32. A connecting sleeve 310 is rotatably connected to the outside of the connecting pipe 37. A connecting cover 39 is fixedly installed at one end of the connecting pipe 37, which serves as a support for insertion and limiting, and is used to support its internal and external components.

[0042] like Figure 6 As shown, the elastic component includes a spring 36, which is welded to one end of the inner cavity of the connecting tube 37. An adapter seat 34 is welded to one end of the spring 36, and an adapter groove 35 is opened at one end of the adapter seat 34. The connecting block 32 is inserted into the interior of the adapter groove 35. Based on the elastic pushing principle, it is easy to perform the snap-fit ​​operation. This method is simple and convenient to operate.

[0043] like Figure 6 As shown, the adapter component includes through holes 38, which are respectively opened on both sides of one end of the connecting tube 37. Positioning grooves 311 are opened on both sides of one end of the connecting sleeve 310, and sliding grooves 312 are opened on the inner side wall of the connecting sleeve 310 to facilitate the insertion of the adapter component and limit its position after connection.

[0044] During operation, the flue gas filter body 21 is not inserted into the housing 1. Instead, the flue gas filter body 21 is directly inserted into the connecting pipe 37 along with the connecting seat 31 and the connecting block 32. The connecting sleeve 310 is rotated synchronously, and the connecting sleeve 310 and the connecting pipe 37 are connected by damped rotation. Rotating the connecting sleeve 310 moves the sliding groove 312 to a position that can be matched with the connecting block 32, that is, from the vertical state to the horizontal state. At this time, the connecting block 32 is located inside the sliding groove 312, and the protrusion 33 is inserted into the adapter groove 35. Then, the push is continued, and the adapter seat 34 compresses the spring 36 until it can no longer be pushed. Then, the adapter seat 34 is rotated, so that the connecting block 32 cannot slide inside the through hole 38. Then, the adapter seat 34 is rotated, so that the positions of the sliding groove 312 and the positioning groove 311 are swapped, that is, the state shown in the figure. After that, the pushing force is released, so that the connecting block 32 is locked inside the positioning groove 311, and the installation operation is completed.

[0045] For example, the above method can be used to insert it into the inside of the outer casing 1 for threaded connection;

[0046] When disassembly is required, simply reverse the installation steps above. First, detach the outer casing 1, and then separate the filter element from the installation mechanism 3 for replacement.

[0047] 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.
