Description

Technical Field

[0001] This utility model belongs to the field of air filtration technology, specifically relating to a static axial air outlet plate and frame air filter. Background Technology

[0002] Air filters include automatic roll-up air filters, self-cleaning air filters, and static plate and frame air filters. Automatic roll-up air filters and self-cleaning air filters rely on external power to purify the air, while static plate and frame air filters rely on their own filter elements to purify the air without external power. Plate and frame air filters are air filtration devices at the intake end of large axial flow air compressors.

[0003] Currently, plate and frame air filters have a "U"-shaped layout, meaning that a rectangular housing contains a rectangular clean air chamber formed by interconnected filter element frames. The filter is installed on a 15-meter-high steel structure platform. An opening is located at the bottom of the rectangular clean air chamber, connected to the air compressor inlet below via ductwork and elbows. With industrial upgrading, the intake volume of axial air compressors is continuously increasing. The corresponding intake air filtration equipment is typically designed to handle 1.8-2 times the normal intake volume of the air compressor. To meet the needs of upstream equipment, the air filtration equipment needs to incorporate more filter elements to accommodate the increased intake volume. This usually involves increasing the volume of the filter element frames to accommodate more filters. However, the current "U"-shaped plate and frame air filter structure occupies a large space, and the cost increases with the increased volume. With the continuous advancement of air compression technology, even larger intake volume air filtration requirements will emerge. Simply increasing the equipment volume to install more filter elements is clearly insufficient to meet the needs of upstream equipment. Utility Model Content

[0004] The purpose of this invention is to propose a static axial outlet plate and frame air filter. By setting multiple interconnected U-shaped air ducts consisting of filter element frames and filter elements inside the filter, the needs of industrial upgrading can be met without changing the volume of the plate and frame air filter. Under the same air intake, the volume of the plate and frame air filter is reduced by 60%-70% compared with the prior art, thereby saving equipment space and reducing purchase costs for enterprises.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A static axial outlet plate-and-frame air filter, comprising an air inlet, an air outlet, and a filter element frame for mounting filter elements; the filter element frame is sealed between the top and bottom plates of the plate-and-frame air filter; one end of two filter element frames I are sealed to a side plate I of the plate-and-frame air filter, and the side plate I is connected to the air outlet or the air inlet of the plate-and-frame air filter; a plurality of filter element frames II are arranged between the two filter element frames I; the filter element frames II are parallel to the filter element frames I; both ends of each filter element frame II are connected to an adjacent filter element frame I or an adjacent filter element frame II by connecting elements to form a plurality of interconnected U-shaped air ducts; the connecting elements are connecting plates or connecting frames for mounting filter elements.

[0007] The plate and frame air filter has at least one air outlet that is directly connected to the air inlet of the air compressor located on the same horizontal pipe axis, thus eliminating the resistance drop caused by multiple pipe bends.

[0008] This utility model proposes a static axial outlet plate and frame air filter. The plate and frame air filter is designed with multiple interconnected U-shaped air ducts, which are composed of filter element frames and filter elements. The design of multiple U-shaped air ducts allows for a larger air intake volume without changing the filter volume, and also provides air intake and negative pressure functions. This maximizes the use of the internal space of the filter. Compared with the prior art, the volume of the static axial outlet plate and frame air filter is reduced by 60%-70% under the same air intake volume, thereby saving equipment space and reducing purchase costs for enterprises.

[0009] Compared with existing technologies, the air outlet is located on the side of the equipment, so the filter does not need to be installed in a high position. The air outlet can be directly connected to the air compressor inlet on a horizontal pipe axis, eliminating the resistance drop caused by multiple pipe bends. Attached Figure Description

[0015] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

[0016] Example 1: As Figure 1 , Figure 2 As shown, a static axial air outlet plate-and-frame air filter has an air inlet, an air outlet 2, and a filter element frame for mounting filter elements 6. The filter element frame is sealed between the top plate and the bottom plate 9 of the plate-and-frame air filter. One end of two filter element frames I3 are sealed to the side plate I1 of the plate-and-frame air filter, and the side plate I1 is connected to the air outlet 2 of the plate-and-frame air filter. The air outlet 2 is directly connected to the air inlet of a large axial flow air compressor through an air outlet connecting flange 10, eliminating the resistance drop caused by multiple pipe bends. An air inlet is provided on the side plate II13 corresponding to the air outlet 2, and a rainproof grille 5 is installed on the air inlet. Multiple filter element frames II4 parallel to the filter element frames I3 are arranged between the two filter element frames I3. Each filter element... Both ends of frame II4 are connected to adjacent filter element frames I3 or II4 via connecting elements 12 to form multiple U-shaped air ducts 8. This allows the gas entering the multiple U-shaped air ducts 8 to communicate with each other through the filter element frames II4 and the filter elements 6 installed on the filter element frames II4, and to be discharged through the air outlet under negative pressure. The connecting element 12 can be a connecting plate or a connecting frame for installing filter elements. If sufficient air intake can be ensured, the connecting element 12 can be a connecting plate, that is, the connection end between filter element frame II4 and adjacent filter element frames I3 or II4 is closed. The air entering the U-shaped air duct is filtered by the filter elements 6 on filter element frames I3 and II4 and then flows out through the air outlet 2. To further increase the air intake, the connecting element 12 can be a connecting frame for installing filter elements 6.

[0017] To further increase the air intake, air inlets can be installed on one of the side plates II13 on both sides of the side plate I1 where the air outlet 2 is located, or on both side plates II13.

[0018] refer to Figure 3 The side plate I1 can also be connected to the air inlet of the plate and frame air filter.

[0019] To further increase the air intake, bottom air intake can be added. For example, the bottom plate 9 of the plate-and-frame air filter can be spaced slightly from the ground or platform, allowing air to enter through the bottom plate 9. To achieve bottom air intake, the bottom plate 9 can be designed with a grille structure. Figure 4 .
