Description

Technical Field

[0001] The utility model relates to an exhaust gas dust removal device, belonging to the technical field of dust removal equipment. Background Art

[0002] In the existing chemical tail gas dust removal system, cyclone dust removal, bag dust removal, spray dust removal, etc. are commonly used. However, these conventional dust removal methods have their own shortcomings, such as low efficiency of cyclone dust removal and incomplete dust removal; large resistance of bag dust removal and easy damage of bags; spray dust removal requires a large amount of water and high operating costs. Therefore, the utility model is proposed. Summary of the invention

[0003] In view of the shortcomings of the prior art, the utility model provides an exhaust gas dust removal device, which pre-treats the source of dust-containing exhaust gas and blocks the dust twice as a whole, which can effectively prevent dust accumulation in the pipeline, facilitate observation and cleaning, and improve the dust removal efficiency.

[0004] The technical solution of the utility model is as follows:

[0005] An exhaust gas dust removal device comprises a first dust removal mechanism and a second dust removal mechanism, wherein the first dust removal mechanism is connected in series with the second dust removal mechanism via a pipeline;

[0006] The first dust removal mechanism includes a box body, the lower side of the box body is a first air inlet, the upper side of the box body is a first air outlet, a plurality of dust removal layers are arranged from top to bottom in the box body, the dust removal layer includes a plurality of evenly arranged and inclined dust removal plates, the second dust removal mechanism includes a tank body, a second air inlet is arranged on the lower side of the tank body, the second air inlet is connected to the first air outlet, and a second air outlet is arranged on the upper part of the tank body.

[0007] Preferably, according to the utility model, the dust removal layer is provided with at least two layers, the bottoms of several dust removal plates in the dust removal layer are fixed in the box body by at least two support rods, at least two fixing rods are arranged through the upper part of several dust removal plates, the two ends of the fixing rods are fixed by bolts, and the dust removal plates are fixed by the support rods and the fixing rods.

[0008] According to the preferred embodiment of the utility model, the dust removal plate has an inclination angle of 45°, which greatly reduces wind resistance while collecting dust.

[0009] Preferably, according to the present invention, the box body is a hollow rectangular parallelepiped, a cover plate is provided on one side of the box body through a hinge, and a handle is provided on the cover plate. When too much dust accumulates, the cover plate is opened to clean the internal dust removal layer.

[0010] Preferably, according to the present invention, a transparent viewing mirror is provided on one side of the tank body to facilitate observation of the dust situation inside.

[0011] According to the utility model, a water inlet is provided on the tank body opposite to the transparent mirror, and a drainage hole is provided at the bottom of the tank body. When dust and particles accumulate in the tank body, water is introduced through the water inlet to flush the inside of the tank body, and dust particles are removed through the drainage hole.

[0012] When in use, the first air inlet of the box is installed on the vertical pipe of the dust-containing exhaust gas source. After the exhaust gas enters the first dust removal mechanism, it collides with the dust removal plate. Part of the dust will fall back to the dust-containing exhaust gas source along the vertical pipe, and part of the dust will hang on the dust removal plate, achieving the dust removal effect.

[0013] The exhaust gas passing through the first dust removal mechanism enters the second dust removal mechanism. Since the second air inlet is arranged on the side of the tank body, the exhaust gas enters the second dust removal mechanism tangentially, forming a vortex inside the tank body. The particles and dust contained in the exhaust gas will rub and collide with the tank body and fall to the bottom of the tank body, thereby achieving a dust removal effect. At the same time, the tangential feeding can greatly reduce the wind resistance. The exhaust gas that has undergone two dust removal processes is discharged into the next process through the second air outlet.

[0014] The beneficial effects of the utility model are:

[0015] 1. The first dust removal mechanism of the utility model can block large dust particles in the exhaust gas from falling into the lower pipe when passing through the dust removal plate, and fine dust stays on the dust removal inclined plate, greatly reducing the accumulation of dust in the exhaust gas pipeline.

[0016] 2. The first dust removal mechanism of the utility model adopts an inclined dust removal plate design, which greatly reduces wind resistance and improves operating efficiency while collecting dust.

[0017] 3. The second dust removal mechanism of the utility model adopts tangential feeding, which can block the particulate matter and dust in the exhaust gas from falling into the tank below when passing through the equipment, greatly reducing the accumulation of dust in the exhaust gas pipeline, and greatly reducing wind resistance on the basis of removing dust.

[0018] 4. The second dust removal mechanism of the utility model adopts a spray water flushing device, which is easy to operate and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below through embodiments and in conjunction with the accompanying drawings, but is not limited thereto.

[0026] Embodiment 1:

[0027] like Figure 1-5 As shown, this embodiment provides an exhaust gas dust removal device, including a first dust removal mechanism and a second dust removal mechanism, wherein the first dust removal mechanism is connected in series with the second dust removal mechanism through a pipeline;

[0028] The first dust removal mechanism includes a box body, the lower side of the box body 2 is a first air inlet 7, the upper side of the box body is a first air outlet 1, and three dust removal layers are arranged from top to bottom in the box body 2, and each dust removal layer includes a number of evenly arranged and inclined dust removal plates 4. The second dust removal mechanism includes a tank body 16, and a second air inlet 14 is arranged on the lower side of the tank body 16. The second air inlet 14 is connected to the first air outlet 1 through a pipeline, and a second air outlet 11 is arranged on the upper part of the tank body 16.

[0029] The bottoms of several dust removal plates 4 in the dust removal layer are fixed in the box body by two support rods 3, and two fixing rods 6 are arranged through the upper parts of several dust removal plates. Both ends of the fixing rods 6 are fixed by bolts 5, and the dust removal plates 4 are fixed by the support rods 3 and the fixing rods 6.

[0030] The dust removal plate 4 has an inclination angle of 45°, which greatly reduces wind resistance while collecting dust.

[0031] The box body is a hollow rectangular parallelepiped, and a cover plate 10 is provided on one side of the box body through a hinge 8. A handle 9 is provided on the cover plate 10. When too much dust accumulates, the cover plate is opened to clean the internal dust removal layer.

[0032] A transparent viewing mirror 12 is provided on one side of the tank body 16 to facilitate observation of the dust inside.

[0033] The tank body is provided with a water inlet 15 on the opposite side of the transparent sight glass 12, and the bottom of the tank body is provided with a drain hole 13. When the dust and particles in the tank body accumulate a lot, water enters through the water inlet 15 to flush the inside of the tank body, and the dust particles are removed through the drain hole.

[0034] When in use, the first air inlet of the box is installed on the vertical pipe of the dust-containing exhaust gas source. After the exhaust gas enters the first dust removal mechanism, it collides with the dust removal plate. Part of the dust will fall back to the dust-containing exhaust gas source along the vertical pipe, and part of the dust will hang on the dust removal plate, achieving the dust removal effect.

[0035] The exhaust gas passing through the first dust removal mechanism enters the second dust removal mechanism. Since the second air inlet is arranged on the side of the tank body, the exhaust gas enters the second dust removal mechanism tangentially, forming a vortex inside the tank body. The particles and dust contained in the exhaust gas will rub and collide with the tank body and fall to the bottom of the tank body, thereby achieving a dust removal effect. At the same time, the tangential feeding can greatly reduce the wind resistance. The exhaust gas that has undergone two dust removal processes is discharged into the next process through the second air outlet.
