Description

Technical Field

[0001] The utility model relates to the technical field of flue gas reuse treatment, in particular to a high-temperature flue gas return burning and reuse device. Background Art

[0002] In the process of industrial production, the emission of high-temperature flue gas is a common phenomenon. Especially in energy-consuming equipment such as sintering machines, boilers, and kilns, high-temperature flue gas not only carries a large amount of heat energy but also may contain harmful substances such as dust. The traditional flue gas emission method not only causes energy waste but also exacerbates environmental pollution. Therefore, it is necessary to use a high-temperature flue gas return burning and reuse device to filter the high-temperature flue gas and then recover and reuse the heat energy in the high-temperature flue gas, so as to improve energy efficiency and reduce the negative impact on the environment.

[0003] However, although the high-temperature flue gas return burning and reuse devices on the market have achieved heat energy recovery to a certain extent, there are serious defects in the design of the filtering mechanism. The filter plates in the filtering mechanism usually adopt fixed filter plates. After filtering the flue gas for a long time, a large amount of dust and harmful substances are easily accumulated on the surface of the filter plates, which is extremely likely to cause blockage of the filter plates. The fixed filter plates are not convenient for disassembling the filter plates, which is not conducive to later cleaning or replacement, and seriously affects the filtering efficiency of high-temperature flue gas. Therefore, we provide a high-temperature flue gas return burning and reuse device to solve the above problems. Content of the Utility Model

[0021] Such asFigures 1 to 5 As shown, a high-temperature flue gas backburning and recycling device includes a workbench 1, a filter mechanism 2 is installed on the upper surface of the workbench 1, and a clamping mechanism 3 is installed on the side of the filter mechanism 2. The filter mechanism 2 includes a filter box 201, and the filter box 201 is fixedly connected to the upper surface of the workbench 1. Two slide rails 202 are fixedly connected to the inner wall of the filter box 201, and the two slide rails 202 are symmetrically distributed on the inner walls of both sides of the filter box 201. A sealing cover 203 is provided on the upper surface of the filter box 201, and a filter plate 204 is fixedly connected to the bottom surface of the sealing cover 203. The filter plate 204 is arranged inside the filter box 201, and sliders 205 are fixedly connected on both sides of the filter plate 204.

[0022] In this device, the operation of the solenoid valve 9 and the fan 12 is controlled by an external control switch. The high-temperature flue gas can be filtered through the filter mechanism 2 installed on the upper surface of the workbench 1, so that the dust and harmful substances in the flue gas can be filtered out to facilitate discharge. The slide rail 202 and the slider 205 in the filter mechanism 2 are slidably connected to facilitate the disassembly of the filter plate 204. The sealing cover 203 can ensure good sealing of the filter plate 204 after installation.

[0023] The two sliders 205 are respectively slidably connected to the inside of the two slide rails 202, and the filter plate 204 is slidably connected to the slide rails 202 through the sliders 205. There are two threaded grooves 206 on the upper surface of the sealing cover 203, and the two threaded grooves 206 are symmetrically distributed on the upper surface of the sealing cover 203. There are two clamping mechanisms 3, and the two clamping mechanisms 3 are symmetrically distributed on both sides of the filter box 201. The clamping mechanism 3 includes a sleeve 301, and the sleeve 301 is fixedly connected to the side of the filter box 201.

[0024] When the filter plate 204 needs to be cleaned or replaced, the threaded column 304 is rotated to disengage it from the threaded groove 206, and then the L-shaped block 303 is moved. With the cooperation of the rotating shaft 302 and the sleeve 301, the fixation of the sealing cover 203 is cancelled, and the sealing cover 203 is pulled. With the cooperation of the slide rail 202 and the slider 205, the filter plate 204 can be pulled out. This setting optimizes the installation method of the filter plate 204 and the filter box 201, making it more convenient to disassemble and more conducive to cleaning or replacing the filter plate 204 at a later time, so as to avoid affecting the filtering efficiency of the high-temperature flue gas.

[0025] The upper surface of the workbench 1 is fixedly connected with a water tank 4. The water tank 4 is arranged to the right of the filter box 201. A total of two mounting brackets 5 are fixedly connected to the inner walls on both sides of the water tank 4. A heat exchange spiral tube 6 is installed between the two mounting brackets 5. The upper surface of the water tank 4 is provided with a water inlet hopper 7. The bottom surface of the water tank 4 is provided with a water outlet pipe 8.

[0026] By opening the water inlet hopper 7, water can be filled into the water tank 4. The setting of the mounting bracket 5 provides stable support for the heat exchange spiral tube 6. With the cooperation of the heat exchange spiral tube 6 and water, heat exchange can be carried out on the high-temperature flue gas, and the water can be heated by the heat energy of the high-temperature flue gas, realizing the reuse of the heat energy of the high-temperature flue gas. By controlling the solenoid valve 9 to open through an external control switch, the heated water can be discharged through the water outlet pipe 8.

[0027] An air inlet pipe 10 is installed on the left side surface of the filter box 201. A connecting pipe 11 is installed on the right side surface of the filter box 201.

[0029] An air outlet pipe 13 is installed on the right side surface of the water tank 4, and the left end of the air outlet pipe 13 is communicated with the right end of the heat exchange spiral tube 6.

[0033] Working principle: When the device is in use, the water tank 4 is filled with water by opening the water inlet hopper 7, and then the fan 12 is controlled by the external control switch to drain the high-temperature flue gas. The high-temperature flue gas is then allowed to enter the interior of the filter box 201 through the air inlet pipe 10, and the high-temperature flue gas is filtered by the filter plate 204. The filtered high-temperature flue gas enters the interior of the heat exchange spiral tube 6 through the connecting pipe 11. Under the cooperation of the heat exchange spiral tube 6 and the water, the high-temperature flue gas is heat-exchanged, and the water is heated by the heat energy of the high-temperature flue gas, and the heat energy of the high-temperature flue gas is transferred to the heat exchanger. The flue gas after heat exchange is discharged through the outlet pipe 13, and then the solenoid valve 9 is opened by the external control switch to discharge the heated water through the outlet pipe 8 for people to use. When the filter plate 204 needs to be cleaned or replaced, the threaded column 304 is rotated to disengage it from the threaded groove 206, and then the L-shaped block 303 is moved. With the cooperation of the rotating shaft 302 and the sleeve 301, the fixing of the sealing cover 203 is cancelled, and the sealing cover 203 is pulled. With the cooperation of the slide rail 202 and the slider 205, the filter plate 204 can be pulled out.
