[0001] This utility model belongs to the technical field of industrial flue gas dust removal equipment, specifically referring to an industrial flue gas dust removal device. Background Technology

[0002] Industrial production is an indispensable part of modern life. However, the actual situation varies for different industrial production processes. For example, many industrial production processes generate a certain amount of industrial fumes, which often contain substances and dust that are harmful to human health and the atmosphere. Currently, bag filters are commonly used to remove dust from industrial fumes.

[0003] Currently, after long-term use, the applicant has found that the baghouse dust collectors used on the market have the following problems in removing dust from flue gas:

[0004] 1. Different industrial production processes produce different flue gases. Some flue gases contain high levels of water vapor. When flue gas containing water vapor enters the bag filter directly and comes into contact with the filter bags, it is easy for scale to form, which leads to easy aging of the equipment and high maintenance costs.

[0005] 2. When the filter bags used in the baghouse dust collector are cleaned by jet cleaning, stubborn dust adheres to the bags and is difficult to remove. Long-term use can easily reduce the dust removal efficiency of the dust collection equipment. Utility Model Content

[0006] This invention addresses at least the problems of dust collectors easily caking when removing dust from flue gas with high moisture content, and the difficulty in cleaning the dust adhering to the filter bags, which ultimately affects the use of the equipment.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes an industrial flue gas dust removal device, including a housing for flue gas dust removal.

[0011] As a preferred embodiment: the anti-caking bag filter assembly includes a filter bag fixed inside the housing with an opening on one side. A support ring is wrapped around the opening end of the filter bag, and the opening end is located below the electromagnetic pulse assembly. An annular support seat is snapped onto the outside of the support ring. One side of the support seat extends into the filter bag, and the support seat is provided with a hook to hook the support seat onto the support ring and connect it to the filter bag.

[0012] As a preferred embodiment, the filter bag support assembly includes a cylindrical fixed frame that extends into the filter bag from its opening. A concentrated impact member is passed through the circumference of the fixed frame. The concentrated impact member consists of a hollow tube that passes through the fixed frame and a hollow sphere that is connected to the hollow tube. An outlet is provided on one side of the hollow sphere. The concentrated impact member is located between the inner wall of the filter bag and the fixed frame.

[0013] As a preferred embodiment, the heating and dehumidifying assembly includes a flange seat connected to the air inlet, a heating wire is provided inside the flange seat, and the electromagnetic pulse assembly passes through the upper part of the flange seat to counteract the heating wire.

[0014] As a preferred embodiment, the electromagnetic pulse assembly includes a mounting bracket fixed to the side wall of the housing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 and Figure 3 :

[0026] An industrial flue gas dust removal device includes a housing 1 for flue gas dust removal. The housing 1 is equipped with an air inlet device. Symmetrical air inlets 11 and outlets 12 are located on both sides of the housing 1. The height of the air inlets 11 is lower than the height of the outlets 12. Dust-laden flue gas enters the housing 1 through the air inlets 11. After dust removal, clean air is discharged from the outlets 12. A dust hopper communicating with the housing 1 and a support rod supporting the housing 1 are located at the bottom of the housing 1. A solenoid valve is installed on the dust hopper to collect the dust filtered from the flue gas. The device also includes a heating and dehumidifying component 2: installed on the air inlet 11, which preheats and dehumidifies the air entering the housing 1 to prevent dust from entering the housing. The air inside the housing 1 contains moisture, which clumps with dust. The heating and dehumidifying assembly 2 includes a flange seat 21 connected to the air inlet 11. The flange seat 21 is equipped with a heating wire 22, which heats the air to remove moisture. The anti-clumping bag filter assembly 3 is located inside the housing 1 and has several sets, used to filter and remove dust from the flue gas entering the housing 1. The electromagnetic pulse assembly 4 has one end located on the side of the housing 1 and penetrates the housing 1, and the other end is connected to the heating and dehumidifying assembly 2 through a pipeline. It can remove dust from the anti-clumping bag filter assembly 3 and the heating and dehumidifying assembly 2. The electromagnetic pulse assembly 4 penetrates the upper part of the flange seat 21 and counteracts the heating wire 22.

[0027] Please see Figure 4-5 :

[0028] The anti-caking bag filter assembly 3 includes a filter bag 31 fixed inside the housing 1 with an opening on one side. A support ring 32 surrounds the open end of the filter bag 31, and the open end is located below the electromagnetic pulse assembly 4. An annular support seat 33 is snapped onto the outside of the support ring 32. A bag support assembly 34 extends from one side of the support seat 33 into the filter bag 31. The bag support assembly 34 includes a cylindrical fixing frame 341, which extends from the open end of the filter bag 31 into its... Inside, a concentrated impact member 342 is passed through the circumferential surface of the fixed frame 341. The concentrated impact member 342 is composed of a hollow tube 343 that passes through the fixed frame 341 and a hollow sphere 344 that is connected to the hollow tube 343. An outlet 345 is provided on one side of the hollow sphere 344. The concentrated impact member 342 is located between the inner wall of the filter bag 31 and the fixed frame 341. A ring hook 331 is provided on the support seat 33 to hook the support seat 33 onto the support ring 32 and connect it to the filter bag 31.

[0029] The flue gas, after the moisture has been removed, enters the housing 1 and adheres to the filter bag 31, forming clean air which is then discharged from the outlet 12. As the dust on the filter bag 31 increases, the air intake device is shut off, and the electromagnetic pulse assembly 4 is activated to remove dust. The pulse airflow blown by the electromagnetic pulse assembly 4 onto the filter bag 31 blows off the dust. In addition, some of the pulse airflow passes through the hollow tube 343 and the hollow sphere 344 and is directly concentrated on the corresponding position of the filter bag 31. On the one hand, this enhances the dust removal effect on the filter bag 31. On the other hand, even if the air that has not been thoroughly dehumidified by the heating wire 22 comes into contact with the filter bag 31 and clumps together, it can be broken down and knocked off by the concentrated pulse airflow.

[0030] Please see Figure 1 and Figure 2 :

[0031] The electromagnetic pulse assembly 4 includes a mounting bracket 41 fixed to the side wall of the housing 1. The mounting bracket 41 is provided with an air tank 42. The air tank 42 is provided with several pulse valves 43. A group of pulse valves 43 is located above the flange seat 21 and connected to it through a pulse pipe 44. One end of the pulse pipe 44 passes through the flange seat 21 and is directed against the heating wire 22. The remaining group of pulse valves 43 extends out of L-shaped blow pipes 45. The blow pipes 45 pass through the housing 1 and are located above the opening end of the filter bag 31. The bottom of the blow pipes 45 extends out of blow heads 451 that correspond one-to-one with the filter bags 31.

[0032] The pulse valve 43 transmits the airflow through the blow pipe 45, and the blow head 451 blows it to the corresponding filter bag 31 position for dust removal. The number of blow heads 451 is the same as the number of filter bags 31. In addition, one set of pulse valves 43 blows the airflow through the pulse pipe directly onto the heating wire 22, knocking off the dust adhering to the heating wire. Finally, when the next air intake operation is started, the fallen dust is sucked into the filter.

[0033] It is worth noting that the power supply and control switch for the air intake device, solenoid valve, heating wire 22, and pulse valve 43 mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate further.

[0034] 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.
