A boiler flue gas harmless treatment mechanism

Abstract

The utility model discloses a harmless treatment mechanism for boiler flue gas, relates to the technical field of boiler flue gas treatment, and solves the problem that when the flue gas treatment device is in use, a driving motor drives a rotating rod and a brush to rotate, and while the movement is in progress, dust moving with the gas will adhere to the brush. Long-term use will cause a large amount of dust to adhere to the brush, causing the brush to not only be unable to clean the inside of the flue during subsequent movement work, but also increase the friction between the brush and the inner side wall of the flue, and the dust moving with the flue will cause the inside of the flue to be blocked over time, thereby reducing the use efficiency of the device. The utility model comprises a smoke inlet pipe and a cleaning pipe, and a filter is arranged above the smoke inlet pipe, so that when the smoke enters the cleaning pipe, the smoke can be conveniently discharged upward through the filter and enter the inside of the gas filter canister for treatment, while the dust will be blocked by the filter.

Description

Technical Field

[0001] The utility model relates to the technical field of boiler flue gas treatment, in particular to a boiler flue gas harmless treatment mechanism. Background Art

[0002] When a boiler burns an object, a large amount of flue gas will be generated, and a large amount of dust and impurities will also be generated during the combustion, and these dust and impurities will be discharged along with the flue gas. After searching, the patent with the announcement number CN218133845U discloses a flue gas purification device for harmless treatment of aluminum ash, including a pipeline, an electric slide rail is horizontally arranged on the outer wall of the pipeline, an adapted slider is arranged on the electric slide rail, a driving motor is fixedly installed on the upper end face of the slider, a rotating shaft is fixedly connected to the output shaft of the driving motor, a perforation is opened on the side wall of the pipeline, and the end of the rotating shaft away from the driving motor extends to the inside of the pipeline through the perforation and is connected to a support rod at the end, and brushes are arranged at both ends of the support rod. In the utility model, the impurities attached to the inner wall of the pipeline are cleaned by the provided brush, and the ash collecting device is provided to collect the impurities attached to the pipeline to avoid the impurities after cleaning remaining in the pipeline to cause corrosion to the pipeline, thereby extending the service life of the pipeline to a certain extent. However, when the flue gas treatment device is in use, the driving motor drives the rotating rod and the brush to rotate. During the movement, the dust moving with the gas will adhere to the brush.

When the boiler is burning, the generated smoke enters the interior of the cleaning pipe 2 through the smoke inlet pipe 1, and the incoming smoke moves upward through the filter 13, and the dust contained in the smoke will be blocked by the filter 13. At the same time, the rotating motor 10 is turned on to rotate the rotating rod 11, driving the old plate 12 to rotate, and the scraper 12 scrapes the filter 13 to remove the dust attached to the filter 13. The right end of the connecting pipe 3 is fixedly installed with a smoke exhaust pipe 5, and the bottom of the smoke exhaust pipe 5 is fixedly connected with a gas filter canister 6. After the smoke barrel filter 13 moves upward, it enters the interior of the smoke exhaust pipe 5, and the smoke enters the interior of the gas filter canister 6 through the smoke exhaust pipe 5, which can conveniently clean the smoke.

[0019] Example 2

[0020] In this embodiment, Figure 1-3 As shown, a connecting pipe 3 is fixedly installed on the upper end of the cleaning pipe 2, and a water pipe 4 is fixedly installed at the connecting portion between the connecting pipe 3 and the cleaning pipe 2. The lower end of the water pipe 4 enters into the interior of the cleaning pipe 2 by penetrating the connecting portion between the connecting pipe 3 and the cleaning pipe 2. An atomizing nozzle 9 is fixedly installed at the lower end of the water pipe 4. The atomizing nozzle 9 is arranged above the filter screen 13. The upper end of the water pipe 4 is sealed and connected to the water outlet end of the water source. When the smoke is introduced, water enters into the interior of the water pipe 4. At the same time, the atomizing nozzle 9 is opened to make the atomizing nozzle 9 spray downward. The spraying operation is performed to wet the dust and prevent dry dust from floating upwards. A dust box 7 is fixedly installed at the lower end of the cleaning tube 2 and is communicated with the interior of the cleaning tube 2. The front end of the dust box 7 is an opening. A movable box 8 is slidably connected to the interior of the dust box 7. The side walls of the movable box 8 are sealed to the inner side walls of the dust box 7 through sealing gaskets. The scraped dust can directly fall into the interior of the movable box 8. When cleaning the dust, the movable box 8 can be pulled out to clean the dust conveniently.

[0021] It should be noted that in this embodiment, when the boiler flue gas harmless treatment mechanism is used, Figure 1-3As shown, when the boiler is burning, the generated smoke enters the interior of the cleaning pipe 2 through the smoke inlet pipe 1, and the incoming smoke moves upward through the filter 13, and the dust contained in the smoke is blocked by the filter 13. While the smoke is entering, water is allowed to enter the interior of the water pipe 4, and the atomizing nozzle 9 is opened at the same time, so that the atomizing nozzle 9 sprays downward to wet the dust, preventing the dry dust from floating upward all the time, and the wet dust will adhere to the filter 13, so that when the atomizing nozzle 9 is opened, the rotating motor 1 0 is opened, the rotating rod 11 is rotated, the moving plate 12 is rotated, and the scraper 12 scrapes the filter 13 to remove the dust attached to the filter 13, and the scraped dust can directly fall into the inside of the mobile box 8. When cleaning the dust, the mobile box 8 can be pulled out to clean the dust conveniently. After the smoke barrel filter 13 moves upward, it enters the inside of the smoke exhaust pipe 5, and the smoke enters the inside of the gas filter canister 6 through the smoke exhaust pipe 5, which can conveniently clean the smoke.
