Description

Technical Field

[0001] The utility model belongs to the field of filtering equipment, in particular to a novel tail gas filter. Background Art

[0002] Industrial production often produces a lot of exhaust gas, which needs to be treated and meet environmental emission standards before it can be discharged. Filters are a common exhaust gas treatment equipment.

[0003] Chinese invention patent application CN108144421A discloses a dry gas filter, including a tank body, an air inlet at the bottom of the tank body, an exhaust pipe at the bottom of the tank body, and a filter device in the tank body. The device has a simple structure and can effectively filter impurities in natural gas.

[0004] However, during the operation of the filter, dust, impurities and oil brought in from the air inlet will be adsorbed on the surface of the filter element, and will fall off and settle at the bottom over time. The airflow entering the air inlet will roll up the dust and reattach it to the surface of the filter element, which will greatly reduce the service life of the filter element. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a novel exhaust filter.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model provides a novel exhaust filter, comprising a tank body, the top of the tank body is fixedly connected to a sealing head by a flange; an air inlet is provided at the upper part of the tank body, and an air outlet is provided at the bottom; a support plate is provided at the lower part of the tank body, the center of the support plate has a hole and a filter element bracket is provided, a filter element is provided on the filter element bracket, a wire mesh is provided in the tank body, and the wire mesh is located above the support plate and below the filter element; a sewage pipe leading to the outside of the tank body is provided at the bottom of the support plate.

[0008] Preferably, the wire mesh is made of 304 stainless steel.

[0009] Preferably, the thickness of the wire mesh is 5 mm.

[0010] Preferably, the wire diameter of the wire mesh is 0.27 mm.

[0011] Furthermore, an air inlet pressure sensor is provided on the air inlet, and an exhaust pressure sensor is provided on the exhaust port.

[0012] Furthermore, a lifting lug is provided on the top of the head.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The novel exhaust filter provided by the utility model has a layer of wire mesh installed at the bottom of the filter. If there is dust, oil and impurities accumulated at the bottom of the filter, the impurities rolled up by the intake air will be blocked by the wire mesh and will not re-attach to the surface of the filter element, thereby extending the service life of the filter element. The utility model is not only simple and practical, but also has low manufacturing cost and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention.

[0016] In the attached picture:

[0017] Figure 1 It is a schematic diagram of the structure of the exhaust gas filter of the utility model;

[0018] Among them: 1-wire mesh; 2-support plate; 3-filter element bracket; 4-filter element; 5-drain pipe; 6-tank body; 7-air inlet; 8-exhaust port; 9-air inlet pressure sensor; 10-exhaust port pressure sensor; 11-head; 12-lifting ear; 13-flange. DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the novel exhaust filter provided by the utility model comprises a tank body 6, a head 11 is provided on the top of the tank body 6, the head 11 is connected to the tank body 6 through a flange 13, and a lifting lug 12 is provided on the top of the head, so as to facilitate the operator to transport the entire filter. An air inlet 7 is provided on the upper part of the tank body 6, and an air inlet pressure sensor 9 is provided on the air inlet 7. An exhaust port 8 is provided on the bottom of the tank body 6, and an exhaust port pressure sensor 10 is provided on the exhaust port 8. A support plate 2, a filter element bracket 3, a filter element 4, a drain pipe 5 and a wire mesh 1 are provided in the tank body 6. The support plate 2 is fixedly arranged in the lower part of the tank body 6, the center of the support plate 2 is opened and the filter element bracket 3 is installed, the bottom of the filter element 4 is installed on the filter element bracket 3, the wire mesh 1 is arranged above the support plate 2 and below the filter element 4, and the drain pipe 5 is arranged at the bottom of the support plate 2 and extends downward to communicate with the outside of the tank body 6, so that dust, impurities, oil stains, etc. that fall on the support plate during the filtering process can be discharged to the outside of the tank body 6.

[0021] The working process of the utility model is as follows: the tail gas enters the tank body 6 through the air inlet 9, is filtered by the filter element 4, flows from the filter element bracket 3 to the bottom of the tank body 6, and is discharged from the exhaust port 8.

[0022] The air inlet pressure sensor 9 and the air outlet pressure sensor 10 are used to monitor the air pressure at the air inlet 7 and the air outlet 8, respectively. The exhaust gas introduced from the air inlet 7 can fill the entire tank 6, and under the action of pressure, the exhaust gas will naturally pass through the filter element 4, and be discharged from the exhaust port 8 after being filtered, thereby effectively filtering the exhaust gas and reducing the filtering cost, without the need to add other equipment such as a vacuum pump.

[0023] The utility model adds a layer of wire mesh 1 at the bottom of the filter. The wire mesh 1 is made of 304 stainless steel, has a wire diameter of 0.27mm and a folded thickness of 5mm, which can effectively prevent dust, impurities and oil accumulated at the bottom of the filter from being rolled up by the airflow and attached to the surface of the filter element, thereby extending the service life of the filter element.

[0024] The above is a further detailed description of the utility model in combination with a specific implementation method, and it cannot be determined that the specific implementation of the utility model is limited to this; for technical personnel in the field of the utility model and related technical fields, based on the technical solution of the utility model, the expansion and replacement of operating methods and data should all fall within the protection scope of the utility model.
