Description

Technical Field

[0001] The utility model relates to the field of dust removal devices, in particular to a dog house type dust removal device for converter dust removal. Background Art

[0002] Converter steelmaking is one of the most important steelmaking methods in the modern steel industry, with high production efficiency and low cost. However, the converter steelmaking process produces a large amount of high-temperature dusty flue gas, which contains a large amount of particulate matter, harmful gases and recyclables.

[0003] The converter dust removal dog house is mainly the main equipment for collecting secondary high-temperature flue gas and trace CO generated in the production process. The converter dust removal dog house contains converter, movable smoke hood, fixed flue and other equipment. The movable smoke hood in the converter dust removal dog house seals the converter mouth and is responsible for introducing most of the high-temperature flue gas and most of the converter CO into the converter dust removal system for treatment, so as to realize the organized emission of high-temperature flue gas and converter CO.

[0004] The four chain guide holes on the top of the converter doghouse can ensure the normal up and down movement of the driving chain on the movable smoke hood, so that the movable smoke hood can be lowered or raised according to production requirements. After the movable smoke hood is raised, the flue gas will enter the dust removal doghouse. Part of the flue gas and trace CO entering the dust removal doghouse will escape through the chain guide holes, causing the CO concentration in the workshop to exceed the standard, affecting the safe operation of the personnel on duty. Therefore, a doghouse type dust removal device for converter dust removal is proposed. Utility Model Content

[0024] like Figure 3As shown, the dust removal mechanism 6 also includes installation notches 603 opened on both sides of the dust removal box 601, threaded holes 602 are opened on the dust removal box 601 near the edge of the installation notch 603, a chain through hole 608 is opened at the upper end of the dust removal box 601, a pipe interface 607 is fixedly installed on the surface of the dust removal box 601, a docking base 604 is fixedly installed on the bottom of the dust removal box 601, and docking through holes 605 are opened at the four corners of the docking base 604.

[0025] Specifically, the dust extraction pipe 606 is connected to an exhaust pump. After the exhaust pump is started, the dust extraction pipe 606 can extract the gas in the dust removal box 601, thereby forming a negative pressure in the dust removal box 601. After the negative pressure is formed in the dust removal box 601, the smoke escaping from the chain guide hole 4 can be absorbed to prevent the air in the workshop from being polluted.

[0026] like Figure 3 As shown, the oxidation mechanism 7 includes a sealing plate 701 connected to both sides of the dust removal box 601, and an oxidized copper plate 703 is fixedly installed on the sealing plate 701. The oxidation mechanism 7 also includes an electric heating plate 702 fixed on the oxidized copper plate 703, and the electric heating plate 702 is connected to a power supply wire 708.

After the power of the electric heating plate 702 is turned on, it will heat the copper oxide plate 703, and use the hot copper oxide on the surface of the copper oxide plate 703 to react with the carbon monoxide in the dust removal box 601 to generate carbon dioxide, thereby removing the carbon monoxide in the escaping flue gas and preventing the carbon monoxide from escaping into the workshop.

[0028] It should be noted that the utility model is a dog house type dust removal device for converter dust removal. In actual use, the chain winch can be used to wind up the driving chain 5. After winding up the driving chain 5, it will drive the movable smoke hood 2 to move upward to achieve lowering and lifting of the hood. When lifting the hood, the vacuum pump on the dust extraction pipe 606 can be started. Since the dust removal box 601 is installed at the chain guide hole 4 on the upper surface of the dust removal dog house 1 through the docking base 604, the dust extraction pipe 606 is connected to the dust removal box 601 through the pipe interface 607, and the driving chain 5 passes through the dust removal box 601 through the chain through hole 608. Therefore, after starting the vacuum pump, the dust extraction pipe 606 can extract the gas in the dust removal box 601, thereby forming a negative pressure in the dust removal box 601, forming a negative pressure in the dust removal box 601. After forming a negative pressure, the smoke escaping from the chain guide hole 4 can be absorbed. After the smoke escaping from the chain guide hole 4 is absorbed into the dust removal box 601, the power of the electric heating plate 702 can be turned on. Since the fixing screws 706 pass through the fixing legs 704 through the fixing through holes 705 and are connected to the threaded holes 602, the sealing plate 701 is fixed to both sides of the dust removal box 601 by the fixing screws 706. The copper oxide plate 703 extends into the dust removal box 601 through the installation notch 603. Therefore, after the power of the electric heating plate 702 is turned on, it will heat the copper oxide plate 703, and use the hot copper oxide on the surface of the copper oxide plate 703 to react with the carbon monoxide in the dust removal box 601 to generate carbon dioxide, so as to remove the carbon monoxide in the dust removal box 601 and prevent the carbon monoxide from escaping into the workshop.
