A flue gas settling device for incineration

Abstract

This utility model discloses a flue gas settling device, relating to the field of flue gas treatment technology. It includes a flue gas settling platform, a control panel fixedly installed on the front side of the settling platform, a settling cylinder fixedly installed on the top of the settling platform, and a settling chamber fixedly fitted onto the top of the settling cylinder. This utility model utilizes a combination of guide plates, baffles, and filter plates. By injecting flue gas, the guide plates initially guide the flue gas entering the settling chamber, ensuring uniform distribution. Then, particulate matter in the flue gas collides with the baffles under inertia and settles, improving the particulate matter removal rate. The filter further filters the flue gas after the first two stages of settling, trapping tiny particulate matter. This achieves multi-stage settling treatment of the flue gas, extending the residence time of the flue gas in the settling chamber, allowing more time for particulate matter to settle, and effectively improving the settling efficiency.

Description

A snap-fit ​​bracket 11 is fixedly installed on the inner wall of the flue gas settling platform 1 through hole 43. A filter screen plate 12 is movably connected inside the snap-fit ​​bracket 11. Filter screens 13 are detachably connected to the upper and lower ends of the filter screen plate 12. Flue gas is injected into the upper feed chamber 5 through the connecting air pipe 6. The flue gas passes through the guide plate 45 and is evenly distributed in accordance with the size of the guide hole 46, so that the flue gas is evenly distributed. Under the action of inertia, the particulate matter in the flue gas collides with the baffle plate 41 and the guide plate 42 and settles. The flue gas enters the interior of the flue gas settling platform 1 through the flow hole 43. Then, the filter screen 13 further filters the flue gas after the first two stages of settling treatment, intercepting small particulate matter and ensuring that the particulate matter content in the emitted flue gas meets the environmental protection standards. By using the flue gas for multi-stage settling treatment, the residence time of the flue gas in the settling device is extended, allowing the particulate matter more time to settle, which effectively improves the settling efficiency of particulate matter.

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the two ends of the filter screen 13 are threadedly connected with fixing bolts 14, the inner side of the snap-fit ​​bracket 11 is provided with a movable groove 111, the inside of the movable groove 111 is movably installed with a clamping plate 112, one side of the clamping plate 112 is movably connected with a telescopic column 113, the outer side of the telescopic end of the telescopic column 113 is movably sleeved with a spring, the other side of the clamping plate 112 is set on the outer side of the filter screen plate 12, and the filter screen 13 is fixedly installed on the surface of the filter screen plate 12 by the threaded connection of the filter screen 13 with the fixing bolts 14, which facilitates the convenient disassembly of the filter screen. The filter screen plate 12 is placed inside the snap-fit ​​bracket 11, so that the outer side of the filter screen plate 12 pushes the clamping plate 112 to squeeze the telescopic column 113. The spring sleeved on the outer side of the telescopic column 113 generates a rebound force to rebound and press the filter screen plate 12, thereby facilitating the convenient disassembly and replacement of the filter mechanism.

[0035] Example 3

[0036] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a cleaning mechanism is provided on one side of the bottom of the flue gas settling platform 1. The cleaning mechanism includes a dust removal box 7. Frame plates 74 are movably installed on both sides of the inner cavity of the dust removal box 7. A scraper 72 is fixedly installed at one end of the frame plate 74. A pull plate 71 is movably sleeved on one side of the dust removal box 7. The inner side of the pull plate 71 is fixedly connected to one end of the frame plate 74. Particles and dust in the flue gas fall into the interior of the dust removal box 7. The dust removal box 7 is slidably connected and pulled out from the side to discharge the particles, facilitating cleaning and maintenance. Then, the pull plate 71 is pulled to move the frame plate 74, causing the scraper 72 to scrape and move, so that the dust is concentrated to one side inside the dust removal box 7, making it convenient for workers to clean.

[0037] The working principle of this incineration flue gas settling device will be explained in detail below.

[0038] like Figure 1-5 As shown, flue gas is injected into the upper feed chamber 5 through the connecting air pipe 6. The flue gas passes through the guide plate 45, and the size of the guide hole 46 is uniformly distributed, ensuring uniform distribution of the flue gas. Under the action of inertia, the particulate matter in the flue gas collides with the baffle plate 41 and the guide plate 42 and settles. The flue gas passes through the flow hole 43 and enters the flue gas settling platform 1. Then, the filter screen 13 further filters the flue gas after the first two stages of settling, intercepting small particulate matter and ensuring that the particulate matter content in the emitted flue gas meets environmental protection standards. By using the flue gas for multi-stage settling treatment, the residence time of the flue gas in the settling device is extended, allowing the particulate matter more time to settle, effectively improving the settling efficiency of the particulate matter. The filter screen 13 is then connected by the threaded bolts 14. The filter screen 13 is fixedly installed on the surface of the filter screen plate 12, making it easy to disassemble the filter screen. The filter screen plate 12 is placed inside the clip bracket 11, so that the outer side of the filter screen plate 12 pushes the clamping plate 112 to squeeze the telescopic column 113. The spring sleeve on the outer side of the telescopic column 113 generates a rebound force to spring back and press the filter screen plate 12, thereby facilitating the easy disassembly and replacement of the filter mechanism. The particulate dust in the flue gas falls into the interior of the dust removal box 7. The dust removal box 7 is slidably connected and pulled out from the side to discharge the particulate matter, which is convenient for cleaning and maintenance. Then, the pull plate 71 is pulled to move the frame plate 74, which drives the scraper 72 to scrape the dust, so that the dust is concentrated to one side inside the dust removal box 7, which is convenient for the staff to clean.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
