Description

Technical Field

[0001] The utility model relates to the technical field of turbocharger turbulator production devices, in particular to an anode baking furnace tail gas desulfurization and dust removal device for turbocharger turbulators. Background Art

[0002] The roasting furnace can significantly reduce the sintering temperature and energy consumption. It is very helpful to protect the environment, improve efficiency and shorten the time.

[0003] The high-temperature flue gas generated by the roasting furnace during operation contains a large amount of sulfur dioxide and large particulate matter. If it is discharged directly, it will cause a lot of pollution to the environment. Therefore, a flue gas desulfurization device is needed to treat the flue gas.

[0004] For example, a flue gas desulfurization device for a carbon roasting furnace with a turbocharged turbulator disclosed in Chinese patent CN214552431U passes through a flue gas pipe, a three-way valve and an air intake pipe to enter a heat exchanger for cooling. After cooling, the flue gas enters a dust removal assembly at the bottom of the shell through a pipe. The dust removal assembly includes an electrode plate, a mesh plate and a dust collecting trough. When the flue gas passes through the gaps between the electrode plates, the dust therein is adsorbed on the surface of the electrode plate due to the action of the electric field, thereby playing a dust removal role. A dust collecting trough is provided under the electrode plate to collect the dust. Afterwards, the flue gas passes through the dust collecting trough. The connecting pipe enters the top of the shell, and a desulfurization component is installed on the top of the shell. The desulfurization component includes an atomizing nozzle, an absorbent tank and a filter plate. The atomizing nozzle can spray the absorbent in the absorbent tank so that it contacts the flue gas, thereby reacting with the sulfur dioxide in the flue gas to achieve the desulfurization effect, and the precipitate produced after the reaction is retained on the surface of the filter plate, and the excess absorbent falls into the recovery tank for storage. Afterwards, the flue gas enters the heat exchanger through the first circulation pipe, the circulation pump and the second circulation pipe, and circulates until the sulfur dioxide concentration in the flue gas reaches the emission standard and is discharged through the exhaust pipe.

[0005] However, in the prior art, when treating the exhaust gas, the exhaust gas needs to be cooled first, and then the exhaust gas is subjected to dust removal and desulfurization and other treatments. However, in the prior art, when removing dust from the exhaust gas, it is not convenient to disassemble and replace the filter structure, and it is not convenient to collect and clean the dust.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 , this utility model provides a technical solution:

[0029] Example 1:

[0030] The anode baking furnace tail gas desulfurization and dust removal device of the turbocharged turbulator comprises a base 1, a desulfurization structure is installed on the top of the base 1, a dust removal structure is connected to the left side of the desulfurization structure, and a cooling structure is connected to the left side of the dust removal structure.

[0031] The dust removal structure includes a connecting pipe 201, the right end of which is connected to a filter box 202. A filter plate 203 is installed inside the filter box 202. The left bottom of the filter plate 203 is connected to a collection box 204. The middle right side of the filter box 202 is connected to an air supply pipe 205. The outer surface of the filter plate 203 is in sealed sliding connection with the inner wall of a rectangular through-hole in the middle of the top surface of the filter box 202. The outer surface of the collection box 204 is in sealed sliding connection with the inner wall of a rectangular hole in the front of the filter box 202. The left bottom of the filter plate 203 is in sliding connection with the right side of the collection box 204.

[0032] The desulfurization structure includes a spray unit and a connection unit. The spray unit is mounted on top of the connection unit. The spray unit includes a liquid inlet pipe 301. An upper bearing 302 is mounted on the bottom end of the liquid inlet pipe 301. A rotating pipe 303 is connected to the interior of the upper bearing 302. A spiral blade 304 is fixedly mounted on the interior of the rotating pipe 303. A lower bearing 305 is mounted on the bottom end of the outer surface of the rotating pipe 303. The bottom end of the rotating pipe 303 is connected to a spray head 306. The connection unit includes a spray barrel 307. An exhaust pipe 308 is mounted on the middle right side of the outer surface of the spray barrel 307, near the top. A drain pipe 309 is mounted on the middle right side of the outer surface of the spray barrel 307, near the bottom.

[0033] The bottom surface of the spray barrel 307 is fixedly connected to the inside of a groove opened in the middle of the top surface of the base 1, the outer surface of the lower bearing 305 is connected to the inner wall of the mounting hole opened in the middle of the top surface of the spray barrel 307, and the inner wall of a circular hole is opened in the middle of the left side of the outer surface of the spray barrel 307 near the bottom and fixedly connected to the right end of the outer surface of the gas pipe 205.

[0034] By setting up the dust removal structure and installing multiple filter plates 203, the dust particles in the exhaust gas can be filtered, intercepted and adsorbed, and then fall into the collection box 204 by gravity, so that the dust can be collected and centrally processed by the collection box 204, and the filter plates 203 can be disassembled, cleaned and replaced.

[0035] After cooling, the exhaust gas enters the filter box 202 through the connecting pipe 201, and the dust in the exhaust gas is filtered and adsorbed by multiple filter plates 203, thereby effectively removing dust from the exhaust gas, and using gravity to allow the filtered dust to enter the collection box 204, thereby completing the collection of dust particles, making it easier to centrally treat them. After that, the exhaust gas enters the spray barrel 307 through the air supply pipe 205, and the solution is transported through the liquid inlet pipe 301. After the solution enters the rotating tube 303 through the liquid inlet pipe 301, it impacts the spiral blades 304 installed inside the rotating tube 303, so that the spiral blades 304 drive the rotating tube 303 to rotate, so that the rotating tube 303 completes the rotation using the upper bearing 302 installed at the top and the lower bearing 305 installed at the bottom, and drives the spray head 306 to rotate and spray during rotation, thereby completing the desulfurization of the exhaust gas. The exhaust gas after desulfurization is discharged through the exhaust pipe 308, and the desulfurized solution waste liquid is centrally discharged and treated through the drain pipe 309.

[0036] Example 2:

[0037] Based on the first embodiment, the cooling structure includes an air inlet pipe 101, the bottom end of which is connected to a cooling box 102. Refrigerators 103 are installed on the left and right sides of the cooling box 102, and cold guide plates 104 are installed inside the cooling box 102. The front and back surfaces of the cold guide plates 104 are fixedly connected to the front and back surfaces of the inner wall of the cooling box 102. The cold guide plates 104 are installed alternately on the left and right sides of the cooling box 102. A through hole is defined in the middle of the right side of the cooling box 102 near the bottom, which is connected to the left end of the outer surface of the connecting pipe 201.

[0038] By setting up the cooling structure, the cold guide plates 104 are staggeredly installed on the left and right sides of the cooling box 102, so that an S-shaped loop can be formed inside the cooling box 102, thereby increasing the time the exhaust gas passes through the cooling box 102, and utilizing the cooling of the refrigerator 103 and the cold guide plates 104 to more effectively cool the exhaust gas.

[0039] When cooling the exhaust gas, the exhaust gas enters the cooling box 102 through the air intake pipe 101, and the refrigerator 103 is started for cooling at the same time. The refrigerators 103 installed on both sides of the cooling box 102 are used to conduct the cold energy to the cooling box 102 through the cold conduction plates 104. At the same time, the cold conduction plates 104 are staggered on the left and right sides of the cooling box 102 to form an S-shaped loop inside the cooling box 102, thereby increasing the contact area between the exhaust gas and the cold conduction plates 104 and increasing the time the exhaust gas stays in the cooling box 102, thereby better ensuring the cooling effect of the exhaust gas.
