Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology for white fused alumina production, specifically relating to a dust removal device for white fused alumina production. Background Technology

[0002] White corundum is a type of alumina produced by melting industrial alumina powder at temperatures above 2000 degrees Celsius in an electric arc and then cooling it. After crushing, shaping, magnetic separation to remove iron, and sieving into various particle sizes, it is characterized by its dense texture, high hardness, and sharp-angled particle shape. Current white corundum production processes involve melting the powder at temperatures above 2000 degrees Celsius in an electric arc and then cooling it. The process involves crushing, shaping, magnetic separation to remove iron, and sieving into various particle sizes. However, the high-temperature melting process generates a large amount of dust particles, requiring dust removal treatment to reduce air pollution.

[0003] A search revealed a dust removal device for white fused alumina production, disclosed in publication number CN221359202U. The device includes a square outer frame, a dust removal liquid cylinder, and an exhaust gas guide hood. By setting a dust removal chamber inside the square outer frame and installing dust removal components such as activated carbon filter plates, dust removal breathable membranes, and dust removal fiberglass filter bags, the device can effectively remove dust from the exhaust gas. The overall structure is compact and occupies little space.

[0004] However, there are still some shortcomings. For example, the exhaust gas is very hot when it is discharged. Directly discharging it into the dust removal equipment will increase the temperature inside the equipment. The parts inside the equipment are easily damaged or even spontaneously combusted after being affected by the high temperature, which is not conducive to the dust removal equipment's dust removal work.

[0010] In a preferred embodiment, a second valve is connected to the inside of the connecting pipe, and a connecting flange is fixedly connected to one end face of the connecting pipe.

[0011] In a preferred embodiment, a flue gas exhaust pipe is fixedly connected to the other side of the main body of the dust removal equipment, and a dust removal mechanism is fixedly connected to one end of the flue gas exhaust pipe.

[0012] In a preferred embodiment, the dust removal mechanism includes a mounting frame located at one end face of the flue gas exhaust pipe.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-5 This utility model provides a dust removal device for white fused alumina production, including a dust removal device body 1. A dust inlet pipe 2 is fixedly connected to one side of the dust removal device body 1, and a first valve 8 is connected inside the dust inlet pipe 2. A cooling mechanism 3 is provided on the top of the dust removal device body 1, and a connecting pipe 4 is connected to one end of the cooling mechanism 3. The cooling mechanism 3 is used to cool the dust gas generated during the melting of white fused alumina raw materials. A second valve 9 is connected inside the connecting pipe 4, and a connecting flange 5 is fixedly connected to one end of the connecting pipe 4. The connecting pipe 4 and the connecting flange 5 are used to connect to an exhaust device, allowing the dust gas generated during the melting of white fused alumina raw materials to enter the interior of the dust removal device body 1. The first valve 8 and the second valve 9 are used to control the flow rate of the dust gas input. A dust exhaust pipe 6 is fixedly connected to the other side of the dust removal device body 1, and a dust removal mechanism 7 is fixedly connected to one end of the dust exhaust pipe 6.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cooling mechanism 3 includes a cooling pipe 31, one end of which is fixedly connected to one end of the flue gas inlet pipe 2. A liquid storage tank 32 is fixedly connected to the top of the dust removal equipment body 1, and a pump body 33 is fixedly installed on the top of the liquid storage tank 32. An inlet pipe 34 is fixedly connected to one side of the pump body 33, and the end of the inlet pipe 34 extends into a cooling groove 35 opened inside the cooling pipe 31. A first cooling plate 36 and a second cooling plate 37 are fixedly connected inside the cooling groove 35. The first cooling plate 36 and the second cooling plate 37 are integrally formed. The first cooling plate 36 is annular in shape, and the second cooling plate 37 is rectangular in shape. There are multiple first cooling plates 36 and multiple second cooling plates 37. A first drain hole 38 is opened inside the first cooling plate 36, and a second drain hole 39 is opened inside the second cooling plate 37.

[0026] In use, the pump body 33 is started to introduce the coolant stored in the storage tank 32 into the inlet pipe 34. The coolant is then introduced into the cooling tank 35 inside the cooling pipe 31 through the inlet pipe 34. When the high-temperature flue gas enters the cooling pipe 31, the coolant and the first cooling plate 36 and the second cooling plate 37 will exchange the heat of the high-temperature flue gas to cool it down. The first cooling plate 36 and the second cooling plate 37 are made of thermally conductive metal material, which can increase the contact area between the coolant and the heat and improve the cooling effect of the cooling mechanism 3. The first drain hole 38 and the second drain hole 39 facilitate the flow of coolant.

[0027] like Figure 2 As shown, a filling port 310 is provided on the inner side of the top of the liquid storage tank 32. The filling port 310 is connected to the liquid storage tank inside the liquid storage tank 32. The filling port 310 makes it convenient for operators to add new coolant later.

[0028] like Figure 1 and Figure 5 As shown, the dust removal mechanism 7 includes a mounting frame 71, which is located at one end of the flue gas exhaust pipe 6. A first filter screen 72 and a second filter screen 73 are fixedly connected to the inner wall of the mounting frame 71. The second filter screen 73 is close to one end of the first filter screen 72. A sealing connection groove 74 is provided on one end of the mounting frame 71. A sealing connection pipe 75 that matches the sealing connection groove 74 is fixedly connected to one end of the flue gas exhaust pipe 6. The sealing connection pipe 75 is inserted into the inside of the sealing connection groove 74.

[0029] During use, the smoke and dust gas will be filtered by the first filter screen 72 and the second filter screen 73, which can filter dust particles of different sizes. The configuration of the sealing connection groove 74 and the sealing connection pipe 75 makes it convenient for operators to replace and maintain the first filter screen 72 and the second filter screen 73 later.

[0030] Working principle and usage process of this utility model:

[0031] In use, the pump body 33 is started to introduce the coolant stored in the storage tank 32 into the inlet pipe 34. The coolant is then introduced into the cooling tank 35 inside the cooling pipe 31 through the inlet pipe 34. When the high-temperature flue gas enters the cooling pipe 31, the coolant and the first cooling plate 36 and the second cooling plate 37 will exchange the heat of the high-temperature flue gas to cool it down. The first cooling plate 36 and the second cooling plate 37 are made of thermally conductive metal material, which can increase the contact area between the coolant and the heat and improve the cooling effect of the cooling mechanism 3. The first drain hole 38 and the second drain hole 39 facilitate the flow of coolant.
