A flue gas purification device for solid waste treatment

Abstract

This utility model discloses a flue gas purification device for solid waste treatment, including a filter barrel. An air inlet pipe is installed on one side of the filter barrel, and an exhaust pipe is installed on the other side. Sealing components are provided on both the top and bottom sides of the filter barrel. By setting up a drive component and a discharge rack, the space inside the filter barrel can be divided by the sealing rack and the filter screen during use. Flue gas is filtered through the filter screen. After use, the drive motor in the drive component drives the sealing rack and the filter screen to rotate towards the exhaust end through the connecting shaft. During the rotation of the filter screen, the backflushing gas can cause impurities adhering to the filter screen to fall off. At this time, the sealing rack pushes the fallen impurities, and due to the influence of centrifugal force, these impurities will enter the discharge rack for discharge, thereby facilitating the cleaning of the filter screen and improving the filtration efficiency of the filter screen.

Description

Technical Field

[0001] This utility model relates to the field of flue gas purification technology, and in particular to a flue gas purification device for solid waste treatment. Background Technology

[0002] Solid waste treatment refers to the process of classifying, collecting, transporting, treating, and recycling urban solid waste, industrial waste, and construction waste. It usually involves converting waste into heat energy and residual ash through high-temperature combustion. During the combustion process, flue gas is generated, which needs to be treated by purification devices before being discharged.

[0003] Existing flue gas purification devices for solid waste treatment have a large number of impurities in the flue gas produced after combustion during use. During flue gas purification, a filter screen is first needed to filter out the large particulate impurities in the flue gas. However, the filter screen is easily clogged during the filtration process, which affects the filtration efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a flue gas purification device for solid waste treatment.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A flue gas purification device for solid waste treatment includes a filter barrel. An air inlet pipe is installed on one side of the filter barrel, and an exhaust pipe is installed on the other side of the filter barrel. Sealing components are provided on both the top and bottom sides of the filter barrel. A drive component is provided between the sealing components. The drive component includes a drive motor fixed at the middle of the top of the filter barrel. The output end of the drive motor is connected to a connecting shaft. A sealing frame is installed on the outside of the connecting shaft. A filter screen is fixed on one side of the sealing frame, and a discharge rack is installed on one side of the filter barrel.

[0007] Preferably, the air intake pipe and the exhaust pipe are symmetrically distributed on the outside of the filter barrel, and a flange is installed at one end of both the air intake pipe and the exhaust pipe.

[0008] Preferably, the sealing assembly includes an upper sealing plate and a lower sealing plate, and the connecting shaft passes through the upper sealing plate and the lower sealing plate.

[0009] Preferably, the discharge rack has a parabolic structure, and the discharge rack is connected to the filter barrel through a ventilation groove.

[0010] Preferably, a sealing plate is provided at one end of the discharge rack, and the sealing plate is connected to the discharge rack by fixing bolts.

[0011] Preferably, both the sealing frame and the filter screen facing the filter barrel have an arc-shaped structure.

[0012] Preferably, the diameter of the sealing frame and the filter screen after they are connected is the same as the diameter of the filter barrel.

[0013] The beneficial effects of this technology are:

[0014] By setting up a drive assembly and a discharge rack, the space inside the filter barrel can be divided during use by a sealing frame and a filter screen. The flue gas is filtered through the filter screen. After use, the drive motor in the drive assembly drives the sealing frame and filter screen to rotate towards the exhaust end through the connecting shaft. During the rotation of the filter screen, the backflushing gas can make the impurities adhering to the filter screen fall off. At this time, the sealing frame pushes the fallen impurities, and due to the influence of centrifugal force, these impurities will enter the discharge rack and be discharged, thus facilitating the cleaning of the filter screen and improving the filtration efficiency of the filter screen.

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-4As shown in the figure, this embodiment provides a flue gas purification device for solid waste treatment, including a filter barrel 1. An air inlet pipe 2 is installed on one side of the filter barrel 1, through which flue gas enters the filter barrel 1. An exhaust pipe 3 is installed on the other side of the filter barrel 1, through which the filtered flue gas is extracted. Sealing components 4 are provided on both the top and bottom sides of the filter barrel 1. A drive component 5 is provided between the sealing components 4. The drive component 5 includes a drive motor 501 fixed at the middle of the top of the filter barrel 1. The drive motor 501 can drive the connecting shaft 502 to rotate. The output end of the drive motor 501 is connected to the connecting shaft 502. The connecting shaft 502 can drive the sealing frame 503 and the filter screen 504 to rotate. A sealing frame 503 is installed on the outside of the connecting shaft 502. The sealing frame 503 can seal one side of the filter barrel 1. A filter screen 504 is fixed on one side of the sealing frame 503. The filter screen 504 can filter large particulate impurities in the flue gas. A discharge rack 6 is installed on one side of the filter barrel 1. Large particles of impurities after filtration are discharged from filter barrel 1 through discharge rack 6.

[0023] like Figures 1-2 As shown, the air inlet pipe 2 and the exhaust pipe 3 are symmetrically distributed on the outside of the filter barrel 1, and a flange 10 is installed at one end of both the air inlet pipe 2 and the exhaust pipe 3, so that the air inlet pipe 2 and the exhaust pipe 3 can be connected to the external air supply and exhaust pipes through the flange 10.

[0024] like Figures 2-4 As shown, the sealing assembly 4 includes an upper sealing plate 401 and a lower sealing plate 402, and the connecting shaft 502 passes through the upper sealing plate 401 and the lower sealing plate 402, which can seal the top and bottom ends of the filter barrel 1 through the upper sealing plate 401 and the lower sealing plate 402.

[0025] like Figures 1-3 As shown, the discharge rack 6 has a parabolic structure, and the discharge rack 6 is connected to the filter barrel 1 through the ventilation groove 9, so that the separated impurities can enter the discharge rack 6 through the ventilation groove 9 under the influence of centrifugal force.

[0026] like Figures 1-3 As shown, a sealing plate 7 is provided at one end of the discharge rack 6, and the sealing plate 7 is connected to the discharge rack 6 by fixing bolts 8, so that the sealing plate 7 can be installed at one end of the discharge rack 6 by fixing bolts 8.

[0027] like Figures 2-3 As shown, both the sealing frame 503 and the filter screen 504 have an arc-shaped structure on the side facing the filter barrel 1, which facilitates the rotation of the sealing frame 503 and the filter screen 504 inside the filter barrel 1.

[0028] like Figures 2-3 As shown, the diameter of the sealing frame 503 and the filter screen 504 after they are connected is the same as the diameter of the filter barrel 1, which can ensure the sealing of the filter barrel 1 by the sealing frame 503 and the filter screen 504.

[0029] The working principle of this device is as follows: In actual use, the inlet pipe 2 and the exhaust pipe 3 are connected to the external air supply and extraction pipes through the flange 10. The flue gas enters the filter barrel 1 through the inlet pipe 2. Since the sealing frame 503 and the filter screen 504 can seal the inside of the filter barrel 1, the flue gas can only move to the other side of the filter barrel 1 through the filter screen 504 and be discharged from the exhaust pipe 3, thereby achieving the filtration of large particulate impurities. After use, the operator removes the fixing bolts 8 to separate the sealing plate 7 from the discharge rack 6. At this time, the drive motor 501 in the drive assembly 5 drives the sealing frame 503 and the filter screen 504 to rotate towards the exhaust end through the connecting shaft 502. During the rotation of the filter screen 504, the back-blowing gas can make the impurities adhering to the filter screen 504 fall off. At this time, the sealing frame 503 pushes the fallen impurities, and due to the influence of centrifugal force, these impurities will enter the discharge rack 6 and be discharged, thereby facilitating the cleaning of the filter screen 504 and improving the filtration efficiency of the filter screen 504.

[0030] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
