Description

Technical Field

[0001] This utility model belongs to the technical field of environmental protection engineering, specifically relating to a flame-retardant pulse bag filter high-efficiency dust removal device. Background Technology

[0002] The flame-retardant pulse bag filter is an advanced industrial equipment that integrates high-efficiency filtration, flame-retardant protection, and rapid dust removal. It is mainly used to treat industrial waste gas containing flammable and explosive dust or gases, achieving efficient purification of waste gas while ensuring production safety and meeting environmental emission standards.

[0003] However, when dust passes through the fire arrestor mesh, the mesh openings are easily clogged with dust. Once the fire arrestor mesh openings are covered with a large amount of dust, it will cause poor gas flow, increase the air intake resistance of the equipment, affect the processing air volume of the equipment, and fail to effectively block sparks and flames, thus reducing the safety of the fire arrestor system. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant pulse bag filter for high-efficiency dust removal, in order to solve the problem mentioned in the background art that the inside of the flame-retardant mesh is easily clogged by dust when dust passes through it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant pulse bag filter high-efficiency dust removal device, comprising a working chamber and a fixed pipe installed at the front end of the working chamber;

[0006] Multiple pulse generators are equidistantly arranged on the upper circular outer wall of the fixed tube from left to right;

[0007] An air inlet is fixedly connected to the outer wall of the right end of the working chamber;

[0008] The working chamber is equipped with two flame arrestor nets located inside and to the left of the air inlet, and the working chamber is equipped with multiple filter bags.

[0009] Each of the two fire-resistant nets has a fixing block a on its left side, and springs are fixedly connected to the four corners of the outer right wall of each fixing block a and the fire-resistant net.

[0010] According to the fire-resistant pulse bag filter high-efficiency dust removal device as described in the claim, the device is characterized in that: a fixing block b is provided on the right side of each of the two fire-resistant meshes, and rubber balls are fixedly connected to the four corners of the outer wall of the left end of each of the two fixing blocks b.

[0011] Preferably, all of the rubber balls are hollow.

[0012] Preferably, magnetic blocks a are embedded in the four corners of the right outer wall of the two fixed blocks a, and magnetic blocks b are provided in the four corners of the left outer wall of the two fireproof nets.

[0013] Preferably, the plurality of magnetic blocks a and magnetic blocks b repel each other.

[0014] Preferably, a dust collection hopper is fixedly connected to the lower outer wall of the working chamber to collect dust scattered on the filter bag, and a dust collection plate is provided on the lower side of the dust collection hopper.

[0015] Preferably, the dust collection plate is provided with fixing screws on both the left and right sides that engage with the dust collection hopper to limit the position of the dust collection plate.

[0017] Preferably, both of the fire-resistant meshes are made of stainless steel.

[0018] Compared with the prior art, this utility model provides a flame-retardant pulse bag filter high-efficiency dust removal device, which has the following beneficial effects:

[0019] By installing a fixing block a and a spring, when dust-laden gas passes through the inlet and the flame arrestor mesh, the gas will generate impact force and pressure fluctuations on the flame arrestor mesh. Under the action of airflow, the gas can be effectively excited to vibrate, making it easier for the dust attached to the surface of the flame arrestor mesh to fall off under the action of vibration, improving the dust removal efficiency and effectively preventing dust from accumulating on the surface of the flame arrestor mesh and causing blockage. At the same time, when the airflow impacts the flame arrestor mesh, the spring is first subjected to force and undergoes compression deformation, converting part of the kinetic energy of the airflow into the elastic potential energy of the spring. This reduces the direct impact force of the airflow on the flame arrestor mesh, reducing the risk of damage to the flame arrestor mesh structure due to long-term airflow impact, such as preventing deformation and breakage of the metal wire mesh of the flame arrestor mesh, and extending the service life of the flame arrestor mesh.

[0025] 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.

[0026] This utility model provides, for example Figure 1-4 The fire-retardant pulse bag filter high-efficiency dust removal device shown includes a working chamber 1 and a fixed pipe 3 installed at the front end of the working chamber 1;

[0027] Multiple pulse generators 2 are equidistantly arranged on the upper circular outer wall of the fixed tube 3 from left to right;

[0028] An air inlet 4 is fixedly connected to the outer wall of the right end of the working chamber 1;

[0029] Inside the working chamber 1, on the left side of the air inlet 4, are two flame arrestor nets 10. Inside the working chamber 1 are multiple filter bags 9. Dust-laden gas enters the equipment from the air inlet 4 on the right outer wall of the working chamber 1. The gas entering the working chamber 1 first passes through the two flame arrestor nets 10, effectively blocking sparks, flames and other open flames from entering the equipment, while ensuring normal gas flow. After passing through the flame arrestor nets 10, the dust-laden gas continues to flow in the working chamber 1 and then enters the filtration area composed of multiple filter bags 9. When the dust accumulation on the surface of the filter bag 9 is detected to make the filtration resistance reach a certain set value, the pulse generator 2 works according to the preset program and instantly releases high-pressure gas. The high-pressure gas is injected into the filter bag 9 at high speed through the nozzle on the fixed pipe 3, causing the filter bag 9 to expand rapidly. At the same time, the impact force of the airflow and the vibration of the filter bag 9 cause the dust attached to the surface of the filter bag 9 to fall off.

[0030] Each of the two fire-resistant nets 10 has a fixing block a11 on its left side. Springs 13 are fixedly connected to the four corners of the outer wall of the right end of the two fixing blocks a11 and the fire-resistant net 10. When dusty gas impacts the fire-resistant net 10, it will excite the springs 13 to vibrate. The vibration helps to shake off the dust attached to the surface of the fire-resistant net 10, preventing the accumulation of dust from affecting the fire-resistant effect and ventilation performance of the fire-resistant net 10, and ensuring that the fire-resistant net 10 can continuously and effectively block open flames.

[0031] like Figure 4As shown, a fixing block b16 is provided on the right side of each of the two fire-resistant nets 10, and a rubber ball 15 is fixedly connected to the four corners of the outer wall of the left end of each of the two fixing blocks b16. All the rubber balls 15 are hollow.

[0032] When the airflow impacts the fire arrestor mesh 10, the fixed block b16 will generate relative motion due to its own inertia and the elastic effect of the rubber ball 15, causing the right side of the fire arrestor mesh 10 to vibrate. The hollow structure of the hollow rubber ball 15 gives it a certain buffering and elastic deformation capacity, which can absorb and release energy during vibration, further enriching the vibration mode of the fire arrestor mesh 10, enhancing the dust removal effect, and limiting the maximum range of motion of the fire arrestor mesh 10.

[0033] like Figure 4 As shown, magnetic blocks a12 are embedded inside the four corners of the right outer wall of the two fixed blocks a11, and magnetic blocks b14 are installed inside the four corners of the left outer wall of the two fireproof nets 10. The multiple magnetic blocks a12 and magnetic blocks b14 repel each other.

[0034] The mutual repulsion between magnetic block a12 and magnetic block b14 further intensifies the vibration of the flame arrestor mesh 10. This repulsion changes with the displacement of the flame arrestor mesh 10 under the action of airflow, generating an additional vibration force, which adjusts the vibration amplitude and frequency of the flame arrestor mesh 10, and can more effectively shake off the dust attached to the surface.

[0035] like Figure 1 As shown, a dust collection hopper 5 is fixedly connected to the lower outer wall of the working chamber 1 to collect dust scattered on the filter bag 9. A dust collection plate 8 is provided on the lower side of the dust collection hopper 5. Fixing screws 7 that engage with the dust collection hopper 5 are provided on both the left and right sides of the dust collection plate 8 to limit the position of the dust collection plate 8.

[0036] When the pulse generator 2 cleans the filter bag 9, the detached dust falls downwards under the action of gravity, preventing the dust from scattering everywhere at the bottom of the working chamber 1 and improving the dust collection efficiency. When it is necessary to clean the dust in the dust collection hopper 5, the dust collection plate 8 can be removed by unscrewing the fixing screw 7, making it easy to empty the dust.

[0037] like Figure 1 and Figure 2 As shown, a fixing frame 6 is fixedly connected to the lower outer wall of the working chamber 1, and both fire-resistant nets 10 are made of stainless steel.

[0038] The fixed frame 6, which is fixedly connected to the lower outer wall of the working chamber 1, provides stable support for the entire equipment. It bears the weight of the working chamber 1 and its internal components, ensuring that the equipment remains stable during operation and will not tip over or shift due to its own weight or external factors, thus ensuring the safe operation of the equipment. Stainless steel has good high temperature resistance, corrosion resistance and high strength properties. Its high temperature resistance means that the fire barrier mesh 10 will not deform or be damaged due to excessive temperature when facing possible high-temperature sparks or flames, and can continuously and effectively block open flames, ensuring the fire safety of the equipment.

[0039] The implementation principle of this embodiment is as follows: Dust-laden gas enters the equipment from the air inlet 4 on the outer wall of the right end of the working chamber 1. The gas entering the working chamber 1 first passes through two flame arrestor nets 10, which effectively prevent sparks, flames and other open flames from entering the equipment, while ensuring normal gas flow. After passing through the flame arrestor nets 10, the dust-laden gas continues to flow in the working chamber 1 and then enters the filtration area composed of multiple filter bags 9. When the dust accumulation on the surface of the filter bag 9 is detected to make the filtration resistance reach a certain set value, the pulse generator 2 works according to the preset program and releases high-pressure gas instantly. The high-pressure gas is injected into the filter bag 9 at high speed through the nozzle on the fixed pipe 3, causing the filter bag 9 to expand rapidly. At the same time, the impact force of the airflow and the vibration of the filter bag 9 cause the dust attached to the surface of the filter bag 9 to fall off. When the dust-laden gas impacts the flame arrestor nets 10, it will excite the spring 13 to vibrate. The vibration helps to shake off the dust attached to the surface of the flame arrestor nets 10, preventing the dust accumulation from affecting the flame arrestor effect and ventilation performance of the flame arrestor nets 10, and ensuring that the flame arrestor nets 10 can continuously and effectively block open flames.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
