Description

Technical Field

[0001] This utility model relates to a high-temperature resistant flue gas recovery device, belonging to the field of flue gas recovery technology in the metallurgical industry. Background Technology

[0002] Flue gas recovery refers to the process of capturing, purifying, and reusing flue gas generated during industrial production using specific flue gas recovery equipment. This process aims to remove harmful gases from the flue gas while recovering recyclable substances, thereby achieving energy conservation, emission reduction, and environmental protection. The principle of flue gas recovery is mainly based on physical and chemical methods. Through flue gas recovery equipment, flue gas can be purified to remove harmful gases such as nitrogen oxides and sulfur oxides. Especially for the treatment of nitrogen oxides, flue gas recovery technology typically uses catalysts to reduce nitrogen oxides to nitrogen and water, thereby significantly reducing their emission concentration. A recovery fan is required in the flue gas recovery process.

[0003] While current flue gas recovery fans can recover flue gas, the large amount of solid impurities in the flue gas causes them to adhere to the filter screen during filtration, easily clogging it and requiring regular manual cleaning, which is time-consuming and labor-intensive, resulting in poor practical application. To solve these problems, there is an urgent need for a high-temperature resistant flue gas recovery fan. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant flue gas recovery device that can remove impurities adhering to the filter screen while recovering flue gas, avoid clogging of the filter screen, improve the airflow rate, and solve the problems existing in the background technology.

[0005] The technical solution of this utility model is:

[0006] A high-temperature resistant flue gas recovery device includes a flue gas recovery pipe, a flue gas recovery tank, a side box, a connecting pipe, a built-in flue gas filter plate, and a turbulence cleaning component. The flue gas recovery pipe is connected to the flue gas recovery tank, and the recovery tank is connected to the side box through the connecting pipe. A recovery fan is fixedly installed inside the flue gas recovery tank. The flue gas recovery pipe is equipped with a built-in flue gas filter plate and a turbulence cleaning component that cooperates with the built-in flue gas filter plate.

[0007] The built-in flue gas filter plate is fixed inside the flue gas recovery pipe. The turbulence cleaning component includes a scraper, inclined airflow blades, a mounting shaft, and a mounting shaft bracket. One end of the mounting shaft is rotatably connected to the mounting shaft bracket, and the mounting shaft bracket is fixed inside the flue gas recovery pipe. The other end of the mounting shaft is provided with a scraper that cooperates with the built-in flue gas filter plate. Several inclined airflow blades are provided on the mounting shaft.

[0008] The scraper at the other end of the mounting shaft, which cooperates with the built-in flue gas filter plate, consists of three scrapers that are evenly arranged in the circumferential direction of the mounting shaft.

[0009] The contact surface between the scraper and the built-in flue gas filter plate is provided with evenly arranged protrusions, so that the contact surface between the scraper and the built-in flue gas filter plate forms a rough surface.

[0010] The centerline of the mounting shaft coincides with the centerline of the flue gas recovery pipe.

[0011] The oblique airflow blades on the mounting shaft are three blades evenly arranged.

[0012] The flue gas recovery pipes are two identical ones, and the two identical flue gas recovery pipes are respectively connected to the flue gas recovery tank.

[0013] The beneficial effects of this utility model are:

[0014] (1) When in use, the flue gas in the external chimney is recovered to the flue gas recovery tank through the flue gas recovery pipe. At this time, the flue gas can first pass through the built-in flue gas filter plate to filter out the internal particulate impurities. Then the airflow can blow multiple inclined airflow blades. The multiple inclined airflow blades will rotate under the force. As the flue gas continues to be input, the rotation speed of the multiple inclined airflow blades will also increase, thereby further accelerating the input speed of the flue gas. Through this design, the airflow can be used to drive multiple inclined airflow blades to rotate automatically, thereby further improving the airflow rate and thus improving the actual recovery efficiency and effect of the overall equipment.

[0015] (2) While the inclined airflow blades and the mounting shaft rotate, the scraper will also rotate synchronously. The protrusion of the scraper can clean one side of the built-in flue gas filter plate, thereby effectively preventing the filter holes of the built-in flue gas filter plate from becoming clogged, thus continuously ensuring the filtration effect of the built-in flue gas filter plate and ensuring the working effect of the overall equipment. In addition, the fan installed inside the equipment is equipped with high-temperature resistant materials on the outside, thereby effectively improving the high-temperature resistance of the motor and further improving the overall application effect of the equipment.

[0022] The present invention will be further described below with reference to the accompanying drawings and examples.

[0023] See attached document Figure 1-4 A high-temperature resistant flue gas recovery device includes a flue gas recovery pipe 1, a flue gas recovery tank 2, a side box 3, a connecting pipe 5, a built-in flue gas filter plate 6, and a turbulence cleaning component 7. The flue gas recovery pipe 1 is connected to the flue gas recovery tank 2, and the recovery tank 2 is connected to the side box 3 through the connecting pipe 5. A recovery fan is fixedly installed inside the flue gas recovery tank 1. The flue gas recovery pipe 1 is provided with a built-in flue gas filter plate 6 and a turbulence cleaning component 7 that cooperates with the built-in flue gas filter plate 6.

[0024] In this embodiment, refer to the appendix Figure 1-4 The high-temperature resistant flue gas recovery device includes a flue gas recovery pipe 1, a flue gas recovery tank 2, a side box 3, a mounting column 4, a connecting pipe 5, a built-in flue gas filter plate 6, and a turbulence cleaning component 7. There are two identical flue gas recovery pipes 1, which are connected to the flue gas recovery tank 2 respectively. Each flue gas recovery pipe 1 is equipped with a built-in flue gas filter plate 6 and a turbulence cleaning component 7.

[0025] The built-in flue gas filter plate 6 is fixed inside the flue gas recovery pipe 1. The turbulence cleaning component 7 includes a scraper 71, an inclined airflow blade 72, a mounting shaft 73, and a mounting bracket 74. One end of the mounting shaft 73 is rotatably connected to the mounting bracket 74, and the mounting bracket 74 is fixed inside the flue gas recovery pipe 1. The other end of the mounting shaft 73 is provided with a scraper 71 that cooperates with the built-in flue gas filter plate 6. There are three scrapers 71 that are evenly arranged in the circumferential direction of the mounting shaft 73. The contact surface between the scraper 71 and the built-in flue gas filter plate 6 is provided with evenly arranged protrusions 75, so that the contact surface between the scraper 71 and the built-in flue gas filter plate 6 forms a rough surface.

[0026] A recovery fan is fixedly installed inside the flue gas recovery tank 2. The input end of the recovery fan is connected to the flue gas recovery pipe 1. The outside of the recovery fan is covered with high-temperature resistant material.

[0027] Multiple mounting columns 4 are fixedly installed longitudinally inside the side box 3, and the multiple mounting columns 4 are arranged in parallel to each other.

[0028] The working principle is as follows:

[0029] In actual use, the flue gas from the external chimney can be introduced into the flue gas recovery pipe 1. The recovery fan inside the equipment is turned on to recover the flue gas into the flue gas recovery tank 2. At this time, the flue gas can first pass through the built-in flue gas filter plate 6 to filter out the particulate impurities inside. Then, the airflow can blow multiple inclined airflow blades 72. The multiple inclined airflow blades 72 will rotate under force. As the flue gas continues to be input, the rotation speed of the multiple inclined airflow blades 72 will also increase, thereby further accelerating the input rate of the flue gas. While the inclined airflow blades 72 and the mounting shaft 73 are rotating, the scraper 71 will also rotate synchronously. The protrusion 75 of the scraper 71 can clean one side of the built-in flue gas filter plate 6, thereby effectively preventing the filter holes of the built-in flue gas filter plate 6 from being blocked, thus continuously ensuring the filtration effect of the built-in flue gas filter plate 6 and ensuring the working effect of the overall equipment.
