Description

Technical Field

[0001] The utility model relates to the technical field of catalytic combustion devices, in particular to a catalytic combustion device for purifying flue gas. Background Art

[0002] Catalytic combustion is a purification method that oxidizes and decomposes combustible substances in exhaust gas at a relatively low temperature. Therefore, catalytic combustion is also called catalytic chemical conversion. Since the catalyst accelerates the oxidation and decomposition process, most hydrocarbons can be oxidized by the catalyst at a temperature of 300℃ to 450℃. Compared with thermal combustion methods, catalytic combustion requires less auxiliary fuel, lower energy consumption and smaller equipment facilities.

[0003] However, when the existing catalytic combustion device for purifying flue gas is put into use, a filter is provided to prevent the emission of larger smoke particles. Over time, more and more particles will accumulate on one side of the filter, gradually forming a thick sediment layer, which not only affects the filter's rate of smoke flow, but also causes the device to be blocked during use. At the same time, when replacing the filter of most catalytic combustion devices, the staff is required to first remove the flange at the pipe connection, and then the staff reaches into the pipe with tools to remove the filter. Since the interior of the pipe is relatively narrow, it is inconvenient for the staff to remove the filter, which increases the workload of the staff. Utility Model Content

A rotating mechanism 6 is provided on one side of the rotating blade 5. A protrusion 8 is installed in the inner cavity of the exhaust pipe 3. Under the action of the rotating blade 5, the rotating mechanism 6 can be operated to rotate the protrusion 8 in the inner cavity of the exhaust pipe 3. The surface of the protrusion 8 is slidably connected with a connecting block 9. The protrusion 8 drives the connecting block 9 to reciprocate in the inner cavity of the exhaust pipe 3. A vibration mechanism 10 is provided on the other side of the connecting block 9. A filter shell 11 is provided in the inner cavity of the exhaust pipe 3. With the cooperation of the connecting block 9 and the vibration mechanism 10, The filter housing 11 can be reciprocated in the inner cavity of the exhaust pipe 3, which effectively reduces the accumulation of dust on one side of the filter housing 11 and speeds up the rate at which the filter housing 11 discharges gas, thereby improving the practicality of the device. The inner cavity of the exhaust pipe 3 is slidably connected with the mounting housing 12, and the inner cavity of the mounting housing 12 is slidably connected to the surface of the filter housing 11. Under the action of the mounting housing 12, the filter housing 11 can be moved out of the interior of the exhaust pipe 3. The surface of the mounting housing 12 is fixedly connected with a sealing gasket 13, and the surface of the sealing gasket 13 is slidably connected to the inner cavity of the exhaust pipe 3. Under the action of the sealing gasket 13 , effectively preventing the gas from being discharged from the gap between the mounting shell 12 and the exhaust pipe 3, thereby increasing the stability of the device when in use, a handle 14 is bolted to the top of the mounting shell 12, and the handle 14 can facilitate the staff to take out the filter shell 11, thereby facilitating the staff to replace the filter shell 11, thereby reducing the labor of the staff, and a limiting mechanism 15 is provided on the surface of the mounting shell 12. Under the action of the limiting mechanism 15, the mounting shell 12 can be limited, effectively preventing the mounting shell 12 from loosening due to gas, thereby increasing the stability of the device.

[0023] The rotating mechanism 6 includes a rotating shaft 61, one end of which is fixedly connected to one side of the rotating blade 5, and the other end of the rotating shaft 61 is fixedly connected to a bevel gear set 62, and the other side of the bevel gear set 62 is fixedly connected to a rotating rod 63, and both ends of the rotating rod 63 are rotatably connected to the inner cavity of the exhaust pipe 3, and the surface of the rotating rod 63 is fixedly connected to the inner cavity of the protrusion 8. Under the action of the rotating blade 5, the rotating shaft 61 can drive the rotating rod 63 to rotate through the bevel gear set 62, so that the rotating rod 63 drives the protrusion 8 to rotate, and the inner cavity of the exhaust pipe 3 is bolted with a fixing sleeve 7, and the inner cavity of the fixing sleeve 7 is rotatably connected to the surface of the rotating shaft 61. Under the action of the fixing sleeve 7, the rotating shaft 61 is effectively prevented from positional displacement during operation, thereby increasing the stability of the rotating mechanism 6 and thus improving the stability of the device.

[0024] The vibration mechanism 10 includes a compression spring 101, one end of the compression spring 101 is fixedly connected to the surface of the connecting block 9, and the other end of the compression spring 101 is fixedly connected to a fixed block 103, the surface of the fixed block 103 is fixedly connected to the inner cavity of the exhaust pipe 3, and the inner cavity of the fixed block 103 is slidably connected to a moving rod 102, and one end of the moving rod 102 is fixedly connected to one side of the connecting block 9. With the cooperation of the protrusion 8 and the connecting block 9, the compression spring 101 can be compressed and rebounded on one side of the fixed block 103, and with the cooperation of the moving rod 102, the filter shell 11 can be reciprocated in the inner cavity of the mounting shell 12, effectively reducing the accumulation of dust on one side of the filter shell 11, and accelerating the rate at which gas passes through the filter shell 11, thereby improving the practicality of the device.

[0025] The limiting mechanism 15 includes a connecting plate 151, one side of the connecting plate 151 is bolted to the surface of the mounting shell 12, and one side of the purification component 2 is rotatably connected to a rotating shaft 152. The top of the rotating shaft 152 is fixedly connected to a limiting plate 153, and the bottom of the limiting plate 153 is slidably connected to the top of the connecting plate 151. Under the action of the rotating shaft 152, the limiting plate 153 can be rotated to the top of the connecting plate 151, so that the limiting plate 153 can limit the mounting shell 12, effectively preventing the gas from driving the mounting shell 12 to move, thereby improving the stability of the device during use.

[0026] Working principle: First, the staff makes the device work through the controller 4. Under the action of the catalyst inside the purification component 2, the flue gas can be purified, and the gas is discharged to the next stage through the exhaust pipe 3. At the same time, the gas drives the rotating blade 5 to rotate, and the rotating blade 5 drives the bevel gear set 62 to drive the rotating rod 63 to rotate through the rotating shaft 61. The rotating rod 63 drives the protrusion 8 to rotate. When the longer part of the protrusion 8 contacts the connecting block 9, the connecting block 9 drives the compression spring 101 to be compressed on one side of the fixed block 103, so that the connecting block 9 can drive the filter shell 11 to move inside the mounting shell 12 through the fixed block 103. When the longer part of the protrusion 8 and the connecting block 9 are intertwined, the compression spring 101 rebounds. Under the action, the fixing block 103 can be returned to its original position, and under the action of the return spring inside the mounting shell 12, the filter shell 11 can be returned to its original position in the inner cavity of the mounting shell 12, thereby achieving the effect of the filter shell 11 vibrating in the mounting shell 12. When the staff needs to replace the filter shell 11, the staff rotates the shaft 152 to make the limit plate 153 and the top of the connecting plate 151 intertwine with each other, and the staff uses the handle 14 to make the mounting shell 12 drive the filter shell 11 to move upward, and then the staff replaces the filter shell 11. After the replacement is completed, the handle 14 drives the filter shell 11 back to its original position, and then makes the bottom of the limit plate 153 contact with the top of the connecting plate 151 to limit the mounting shell 12.
