Description

Technical Field

[0001] The utility model relates to blast furnace gas power generation purification equipment, belonging to the field of blast furnace gas power generation equipment in the metallurgical industry. Background Art

[0002] In the prior art, such as the Chinese patent, application number: CN202221446800.2, relates to a blast furnace gas power generation purification device, including a cylinder for containing cooling water, a water inlet and a water outlet are provided on the cylinder, a coil cooling section is provided on the delivery pipe, the coil cooling section is located in the cylinder, the upper end of the delivery pipe is connected to the diversion pipe, two groups of purification mechanisms are connected to the diversion pipe, each group of purification mechanisms includes a connecting pipe and a purification box, the lower end of the connecting pipe is connected to the diversion pipe, the upper end of the connecting pipe is connected to the bottom surface of the purification box, an activated carbon filter is installed in the purification box, an air collecting hood is provided above the activated carbon filter, the air collecting hood is fixedly connected to the inner wall of the purification box, and an electric lighter is provided above the air collecting hood.

[0003] The benefits brought by the above patent are: high-temperature exhaust gas enters the cylinder through the delivery pipe, and is cooled by heat exchange with the cooling water in the cylinder to prevent the exhaust gas from being too hot and causing damage to the device. The cooled exhaust gas enters the purification box through the connecting pipe, and the impurities in the exhaust gas are filtered through the activated carbon filter. The filtered exhaust gas is collected at the electric igniter position through the gas collecting hood. The electric igniter is used to ignite the fuel gas and carbon monoxide in the exhaust gas, so that the exhaust gas finally discharged will not have any residual fuel gas and carbon monoxide, thereby improving the purification effect of the device.

[0004] However, it is found through actual use of blast furnaces that the waste gas generated by combustion is mostly carbon dioxide, with a small amount of carbon monoxide. If the carbon monoxide mixed in the carbon dioxide reaches a certain amount and the purity of the carbon monoxide is not high, the method of igniting the mixed gas with an electric lighter may cause an explosion or may fail to ignite. In this way, continuing to use the above-disclosed technical solution may not only lead to poor purification effect of the mixed gas, but also cause safety accidents. Therefore, improvements are needed. Utility Model Content

[0019] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0020] Refer to the attached Figure 1-5 A blast furnace gas power generation purification device includes a purification cylinder 1, an activated carbon filter 2, a circular mounting ring 3, a waterproof exhaust cover 4 and a carbon monoxide oxidation plate 5. The activated carbon filter 2 and the carbon monoxide oxidation plate 5 are respectively arranged in the purification cylinder 1, the activated carbon filter 2 is located at the lower part of the purification cylinder 1, the carbon monoxide oxidation plate 5 is close to the cylinder mouth of the purification cylinder 1, and the circular mounting ring 3 and the waterproof exhaust cover 4 are respectively arranged on the cylinder mouth of the purification cylinder 1.

[0021] In this embodiment, if Figure 1 As shown, the utility model provides a blast furnace gas power generation purification device, including a purification cylinder 1 installed at the exhaust port above the cooling furnace M, wherein the cooling furnace M is the prior art, and an activated carbon filter 2 is installed at the bottom of the purification cylinder 1.

[0022] like Figure 2 , Figure 3 As shown, the upper end of the purification cylinder 1 is open, and a carbon monoxide elimination structure is installed at the opening, and the carbon monoxide elimination structure includes a circular mounting ring 3 detachably mounted at the mouth of the purification cylinder 1, and a waterproof exhaust cover 4 with adjustable exhaust volume is arranged on the top of the circular mounting ring 3, and a honeycomb carbon monoxide oxidation plate 5 is fixed on the lower side of the inner circle of the circular mounting ring 3, wherein the carbon monoxide oxidation plate 5 is a prior art, and carbon monoxide can be oxidized into carbon dioxide, and the specific principle is a prior art, which will not be repeated in the present utility model.

[0023] like Figure 5 As shown, in order to realize the disassembly and assembly of the circular mounting ring 3 and adjust the exhaust volume, an internal thread is provided on the inner wall of the barrel mouth of the purification barrel 1, and an external thread is provided on the outer ring surface of the circular mounting ring 3, and the external thread matches the internal thread.

[0024] like Figure 5 As shown, in the utility model, the cross-section of the waterproof exhaust hood 4 is U-shaped, the top of the circular mounting ring 3 extends out of the upper end of the purification tube 1, and is fixed to the bottom of the top plate of the waterproof exhaust hood 4, and a distance is left between the side plate of the waterproof exhaust hood 4 and the outer surface of the upper end of the purification tube 1, and an exhaust cavity is formed between the top of the carbon monoxide oxidation plate 5 and the top plate of the waterproof exhaust hood 4, and the exhaust cavity is connected to the outside of the purification tube 1.

[0025] like Figure 4 As shown, in order to achieve exhaust, a plurality of outer notches 1-1 arranged at equal intervals are opened on the cylinder wall at the upper end of the purification cylinder 1, and a plurality of inner notches 3-1 arranged at equal intervals are opened on the ring wall at the upper end of the circular mounting ring 3.
