[0002] The equipment that separates dust from flue gas is called a dust collector or dust removal equipment. The pulse dust collector is a new type of high-efficiency pulse dust collector that is improved on the basis of the bag dust collector. It combines the advantages of various pulse jet dust collectors with compartment reverse air, overcomes the disadvantages of insufficient compartment cleaning intensity and uneven air distribution, and expands the application range.

[0003] When ordinary pulse dust collectors encounter air containing a certain amount of water vapor, dust and water vapor will adhere to the filter paper. During pulse dust removal, the dust removal effect is often very poor, and it is difficult to remove dust with water vapor from the filter paper, resulting in the dust removal effect not meeting expectations and reducing the filtration efficiency of the filter paper. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust removal pulse dust collector, which solves the problem that dust with a certain amount of water vapor on the filter paper causes the dust removal effect to fall short of expectations and reduces the filtration efficiency of the filter paper.

The bottom of the vertical pipe is connected by a threaded dust container for storing dust. One end of the air inlet is provided with a baffle plate, which is fixedly connected to the inner wall of the shell.

[0009] Preferably, the vertical tube has multiple inclined plates inside, which are connected to the inner wall of the vertical tube and are arranged in an alternating manner.

[0011] Preferably, an electric push rod is fixedly connected to the top of the slide plate, and the other end of the electric push rod is connected to the outer wall of the housing.

[0012] Preferably, sealing plates are fixedly connected to the top and bottom of the slide plate. The sealing plates are located in the slide groove, and a through groove is opened inside the housing. A sealing gasket is provided between the sealing plate and the through groove.

[0013] This utility model provides a pulse dust collector for dust removal. Compared with the prior art, it has the following advantages:

[0014] 1. This pulse dust collector, by setting up filter paper, mounting head and heating tube, performs pulse cleaning. During pulse cleaning, the pulse gas controller controls the pulse gas to pass through the first pulse tube and mounting head, blowing the filter paper in reverse from top to bottom, thereby blowing off the dust on the filter paper and completing the pulse cleaning process. When the dust contains water vapor, making the dust relatively wet, the wet dust adheres to the filter paper and is difficult to blow off. At this time, the heating tube works to radiate heat the filter paper, drying the wet dust on the filter paper, and then the pulse cleaning process is repeated to remove the dust on the filter paper, thereby preventing the wet dust from clogging the filter paper.

[0015] 2. This type of pulse dust collector features an electric push rod, a sliding plate, and a sliding ring. During the extension and retraction of the electric push rod, the sliding plate moves up and down. The sliding plate, through the sliding ring, moves all the heating tubes up and down, making the filter paper heat up more evenly and preventing the heating tubes from causing the filter paper to overheat in certain areas.

[0016] 3. This kind of dust removal pulse dust collector, by setting a second pulse tube, the pulse gas controller controls the pulse gas to blow towards the heating tube through the second pulse tube, which can clean the heating tube and avoid excessive dust accumulation on the heating tube, which would reduce the heating effect.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a pulse dust collector, including a housing 1, filter paper 14, an air inlet 2, and an air outlet 3. An installation plate 8 is provided inside the housing 1. The filter paper 14 is installed on the installation plate 8 via installation heads 9. The installation plate 8 is connected to the inner wall of the housing 1. Multiple first pulse tubes 10 are provided above the installation plate 8, and each first pulse tube 10 is connected to a corresponding installation head 9. A heating tube 13 is provided below the installation plate 8. A hollow plate 19 is provided above the installation plate 8. The top of the hollow plate 19 communicates with the air outlet 3, and the bottom of the hollow plate 19 communicates with all the installation heads 9. Air moves upward, and clean air filtered by the filter paper 14 enters the interior of the hollow plate 19 through the hollow installation heads 9. Then, the dust particles are conveyed outward through the air outlet 3 and adhere to the filter paper 14, completing the filtration process. During pulse cleaning, the pulse gas controller 15 controls the pulse gas to pass through the first pulse tube 10 and the mounting head 9, blowing the filter paper 14 in reverse from top to bottom, thereby blowing off the dust on the filter paper 14 and completing the pulse cleaning process. When the dust contains water vapor, making it relatively wet, the wet dust adheres to the filter paper 14 and is difficult to blow off. At this time, the heating tube 13 works to radiate heat the filter paper 14, drying the wet dust on the filter paper 14, and then the pulse cleaning process is repeated to remove the dust on the filter paper 14, thereby preventing the wet dust from clogging the filter paper 14.

[0025] A mounting block 11 is provided above the heating tube 13. The bottom of the mounting block 11 is open, and a second pulse tube 12 is provided inside the mounting block 11. The air outlet direction of the second pulse tube 12 is towards the heating tube 13. A pulse gas controller 15 is fixedly installed on the outer wall of the housing 1. The pulse gas controller 15 is connected to all the first pulse tubes 10 and the second pulse tubes 12. Some dust may accumulate on the heating tube 13. The pulse gas controller 15 controls the pulse gas to be blown towards the heating tube 13 through the second pulse tube 12, which can clean the heating tube 13 and prevent excessive dust accumulation on the heating tube 13, which would reduce the heating effect.

[0026] The bottom of the housing 1 is provided with a dust collection hopper 4, and the bottom of the dust collection hopper 4 is connected to a vertical pipe 6. The bottom of the vertical pipe 6 is connected by a threaded dust container 5 for storing dust. One end of the air inlet 2 is provided with a baffle plate 20, which is fixedly connected to the inner wall of the housing 1. The vertical pipe 6 is provided with multiple inclined plates 7, which are connected to the inner wall of the vertical pipe 6 and are staggered. The inclined plates 7 have a turbulence effect on the airflow above the vertical pipe 6, preventing the dust in the dust container 5 from floating up with the airflow again, making the filter paper 14 more prone to clogging.

[0027] A sliding ring is slidably connected to the inner wall of the housing 1. One end of all the heating tubes 13 is fixedly connected to the sliding ring. A sliding plate 17 is fixedly connected to the outer side of the sliding ring. A groove 16 is opened vertically on one side of the housing 1. The sliding plate 17 is slidably connected to the inner wall of the groove 16. An electric push rod 18 is fixedly connected to the top of the sliding plate 17. The other end of the electric push rod 18 is connected to the outer wall of the housing 1. During the extension and retraction of the electric push rod 18, it can drive the sliding plate 17 to move up and down. The sliding plate 17 drives all the heating tubes 13 to move up and down through the sliding ring, so that the filter paper 14 is heated more evenly, while avoiding the heating tubes 13 from heating the filter paper 14 to an excessively high temperature in some areas.

[0028] Sealing plates are fixedly connected to the top and bottom of the slide plate 17. The sealing plates are located inside the slide groove 16. A through groove is opened inside the housing 1, and a sealing gasket is provided between the sealing plate and the through groove. The slide plate 17 seals the slide groove 16 to prevent dusty gas from escaping out through the slide groove 16.

[0029] During operation, dusty gas enters the housing 1 through the air inlet 2. The baffle plate 20 blocks and disturbs the airflow, causing large dust particles to pass directly through the dust collection hopper 4 into the vertical pipe 6 and then fall into the dust container 5. Fine dust particles move upward with the air. Clean air filtered by the filter paper 14 enters the hollow plate 19 through the hollow mounting head 9 and is then conveyed outward through the air outlet 3. Dust particles adhere to the filter paper 14, completing the filtration process. When pulse cleaning is performed, the pulse gas controller 15... The controlled pulse gas passes through the first pulse tube 10 and the mounting head 9, blowing the filter paper 14 in reverse from top to bottom, thereby blowing off the dust on the filter paper 14 and completing the pulse cleaning process. When the dust contains water vapor, making the dust relatively wet, the wet dust adheres to the filter paper 14 and is difficult to blow off. At this time, the heating tube 13 works to radiate heat the filter paper 14, drying the wet dust on the filter paper 14. Then, the pulse cleaning process is repeated to remove the dust from the filter paper 14, thereby preventing the wet dust from clogging the filter paper 14.

[0030] During the extension and retraction of the electric push rod 18, the slide plate 17 can move up and down. The slide plate 17 drives all the heating tubes 13 to move up and down through the sliding ring, so that the filter paper 14 is heated more evenly, while avoiding the heating tubes 13 from heating the filter paper 14 to an excessively high temperature in some areas.

[0031] There may also be some dust on the heating tube 13. The pulse gas controller 15 controls the pulse gas to be blown onto the heating tube 13 through the second pulse tube 12, which can clean the heating tube 13 and prevent excessive dust from accumulating on the heating tube 13, which would reduce the heating effect.

[0032] The inclined plate 7 has a turbulent effect on the airflow above the vertical tube 6, preventing the dust in the dust container 5 from floating up with the airflow again, making the filter paper 14 more prone to clogging.

[0033] The slide plate 17 seals the slide groove 16 to prevent dusty gas from overflowing outward through the slide groove 16.
