Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, and in particular to a novel high-efficiency denitrification filter bag. Background Technology

[0002] In the field of environmental protection, denitrification filter bags are an important dust removal and denitrification equipment, widely used in industrial flue gas treatment. Specifically, they are dust removal filter bags coated or impregnated with desulfurization and denitrification catalysts on the surface of knitted felt. Their denitrification efficiency can reach more than 90%, and even more than 95% under certain working conditions.

[0003] Existing denitrification filter bags are mostly directly fitted onto the support frame. In actual use, it has been found that their stability still needs improvement. They lack a stable connection and the bottom is more prone to shaking during ventilation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as instability, lack of a stable connection, and increased likelihood of shaking at the bottom during ventilation. This invention proposes a new type of high-efficiency denitrification filter bag.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel high-efficiency denitrification filter bag includes a denitrification filter bag body;

[0007] A support frame is used to support the main body of the denitrification filter bag, which is fitted onto the outer wall of the support frame.

[0008] A connecting assembly is used to connect the denitrification filter bag body and the support frame. The connecting assembly is located at the end of the denitrification filter bag body. The connecting assembly includes a bottom ring and an inner ring fixedly located at the top of the bottom ring. The bottom ring is fixedly located at the end of the bag opening of the denitrification filter bag body. A limiting block is fixedly located on the outer wall of the inner ring. A fixing ring is fixedly sleeved on the outer wall of the support frame. An annular groove is formed at the bottom of the fixing ring, and the inner ring cooperates with the annular groove. An arc-shaped inclined sliding groove is formed on the inner wall of the annular groove. A vertical sliding groove is formed inside the annular groove, and one end of the vertical sliding groove is connected to one end of the arc-shaped inclined sliding groove. The limiting block cooperates with the vertical sliding groove and the arc-shaped inclined sliding groove.

[0009] In one possible design, a pressure ring is slidably disposed inside the annular groove.

[0010] In one possible design, a compression spring is provided inside the annular groove, with its two ends fixedly disposed on the inner wall of the annular groove and the top of the compression ring, respectively.

[0011] In one possible design, at least one L-shaped insert is fixedly provided on the outer wall of the support frame, and at least one auxiliary strip is provided on the main body of the denitrification filter bag, with both ends of the auxiliary strip fixedly provided on the inner wall of the main body of the denitrification filter bag.

[0012] In one possible design, the main body of the denitrification filter bag is cylindrical.

[0013] In one possible design, the support frame consists of two rings and a plurality of support rods fixedly disposed between the two rings.

[0014] In this application, during actual use, the main body of the denitrification filter bag is fitted onto the outer wall of the support frame from below, and the L-shaped insertion rod is aligned with the gap between the main body of the denitrification filter bag and its internal auxiliary strip. Then, the bottom ring is rotated so that the limiting block moves to the bottom of the arc-shaped inclined slide groove. The inner ring is then inserted into the annular groove and rotated so that the limiting block moves along the arc-shaped inclined slide groove until it reaches the inside of the vertical slide groove. After that, the inner ring falls down a certain distance so that the limiting block moves to the bottom of the vertical slide groove, thus completing the installation. When the inner ring is inserted into the annular groove, it will press against the pressure ring and move upward. Then, it will be reset by the compression spring so that the pressure ring presses against the inner ring to increase the stability of the connection.

[0015] In this utility model, the novel high-efficiency denitrification filter bag, through auxiliary strips and L-shaped inserts, can connect the end of the denitrification filter bag body to the support frame, thereby reducing bottom swaying and increasing stability;

[0016] In this utility model, the novel high-efficiency denitrification filter bag can connect the main body of the denitrification filter bag and the supporting frame through the limiting block, thereby achieving a stable connection effect, and the operation is simple and convenient.

[0017] In this invention, when using the denitrification filter bag body, after it is placed on the outer wall of the support frame, it is only necessary to ensure that the L-shaped insert is inserted in the designated position to reduce the shaking of the end of the denitrification filter bag body and ensure its stability. The top end can be connected and fixed by simply twisting, thereby ensuring the stability of the denitrification filter bag body during use. Attached Figure Description
