Description

Technical Field

[0001] The utility model relates to the technical field of turbocharger turbulator production, in particular to a flue gas desulfurization device for the exhaust gas of an Acheson graphitization calciner of a turbocharger turbulator. Background Technique

[0002] With the continuous development of China's economy and industrialization process, air pollution has become increasingly prominent. It is proposed to comprehensively implement flue gas desulfurization in the steel industry.

[0003] The limestone-gypsum method has a relatively high desulfurization efficiency, and the utilization rate of desulfurizer is also relatively high. Gaseous pollutants can be absorbed simultaneously with dust, and the corrosive components in the gas can be neutralized. A large amount of flue gas can be treated. However, the process is complex, the investment in the system is relatively high, and there are corrosion and blockage phenomena in the water pump, pipeline, equipment, and chimney during the circulation process, which is not convenient for equipment operation and maintenance, and the operation cost is relatively high. The double-alkali method has a relatively high desulfurization efficiency, a fast absorption rate of sulfur dioxide, less blockage and wear in the tower, and relatively low investment and operation costs. However, the corrosion of equipment, flue, and chimney is relatively serious, and the amount of flue gas treated is relatively small. The rotary spray drying method has a low desulfurization efficiency, a high calcium-sulfur ratio, a high operation cost, the by-products cannot be utilized, and secondary pollution is likely to occur.

[0004] For example, a flue gas desulfurization treatment device with a turbocharger turbulator proposed in a Chinese patent. The high-temperature flue gas of the carbon calciner enters the absorption tower from the flue inlet. The flue gas enters the cyclone pre-cooling device through the pre-cooling device liquid inlet pipe from bottom to top, and is preliminarily cooled through cyclone treatment. The cooled flue gas continues to move upward and enters the device provided with a turbocharger turbulence generator. The flue gas is fully mixed with the slurry sprayed from the upper first turbocharger turbulence water inlet pipe to form an emulsion layer, and the flue gas and the slurry are in the greatest contact. Through the second turbocharger turbulator water inlet pipe, sulfur dioxide in the flue gas reacts with the effective components of lime in the slurry to be removed, and is oxidized by a fan to generate gypsum. The waste gas in the desulfurization process is discharged from the exhaust pipe at the top of the tower. The waste liquid generated in the middle of the tower is received and treated by the receiving basin and the receiving basin return pipe, and the final waste liquid is discharged to the desulfurization return pipe outlet provided at the bottom of the tower body and selectively recovered.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0028] Embodiment 1:

[0029] An Acheson graphitization calciner flue gas tail gas desulfurization device for a turbocharger turbulator, including a base 1, a connection structure is installed at the top of the base 1, a spraying structure is installed in the middle of the top end of the connection structure, and a filtering structure is connected to the right side of the bottom of the connection structure.

[0030] The spraying structure includes a rotating unit and a spraying unit. The spraying unit is arranged at the bottom of the rotating unit. The rotating unit includes a flange 201. A water inlet pipe 202 is connected to the middle of the left side of the flange 201. A bearing one 203 is installed at one end of the water inlet pipe 202 far from the flange 201. A rotating pipe 204 is installed inside the bearing one 203. A spiral blade 205 is installed inside the rotating pipe 204. A bearing two 206 is installed at the bottom end of the outer surface of the rotating pipe 204. The spraying unit includes a connecting pipe 207. An atomizing nozzle 208 is installed in the middle of the outer surface of the connecting pipe 207. A spraying head 209 is installed at the bottom end of the connecting pipe 207.

[0031] The top end of the connecting pipe 207 is connected to the bottom end of the rotating pipe 204. The top end of the outer surface of the rotating pipe 204 is connected to the inside of the bearing one 203. The bearing one 203 and the bearing two 206 are sealed bearings.

[0032] The connection structure includes a desulfurization tower 101. An air inlet pipe 102 is installed near the bottom end of the middle of the left side of the outer surface of the desulfurization tower 101. An exhaust pipe 103 is installed near the top end of the middle of the right side of the outer surface of the desulfurization tower 101. A swirl plate 104 is fixedly installed inside the desulfurization tower 101. The bottom end of the desulfurization tower 101 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 air inlet pipe 102 is connected to the inside of a circular hole opened near the bottom end of the left side of the outer surface of the desulfurization tower 101. The outer surface of the exhaust pipe 103 is connected to the inside of a circular hole one opened near the top end of the middle of the right side of the desulfurization tower 101. The inside of an installation hole opened in the middle of the top surface of the desulfurization tower 101 is connected to the outer surface of the bearing two 206.

[0033] Through the setting of the spraying structure, when the spraying solution enters the inside of the rotating pipe 204 through the inside of the water inlet pipe 202, it impacts the spiral blade 205, so that the rotating pipe 204 drives the connecting pipe 207, the atomizing nozzle 208, and the spraying head 209 to rotate and spray by using the installation of the first bearing 203 and the second bearing 206, thereby making the contact area between the solution and the flue gas larger and the desulfurization effect better.

[0034] When treating flue gas and tail gas, sodium hydroxide solution or limestone slurry is transported through the inside of the water inlet pipe 202. When the solution enters the inside of the rotating pipe 204 through the inside of the water inlet pipe 202, it impacts the spiral blade 205 inside the rotating pipe 204, so that the spiral blade 205 drives the rotating pipe 204 to rotate by using the impact force. Due to the first bearing 203 and the second bearing 206 installed at the top and bottom of the outer surface of the rotating pipe 204, the rotating pipe 204 can drive the connecting pipe 207 to rotate, and the connecting pipe 207 drives the atomizing nozzle 208 and the spraying head 209 to rotate and spray. By using the upward atomizing spray of the atomizing nozzle 208, the atomizing and sedimentation effect of the solution can be better. At the same time, in cooperation with the spraying of the spraying head 209 on the flue gas, the contact area between the flue gas and the solution is effectively increased. The spraying head 209 sprays and desulfurizes the thicker flue gas at the bottom, while the atomizing nozzle 208 can further desulfurize the thin flue gas rising after the reaction by atomizing the solution. After the flue gas enters the desulfurization tower 101 through the air inlet pipe 102, affected by the swirl plate 104, the flue gas rotates and rises along the guidance of the swirl plate 104, delaying the rising speed of the flue gas and increasing the contact time and contact area between the solution and the flue gas, so that the desulfurization effect is better.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, the filtering structure includes a water outlet pipe 301. The right end of the water outlet pipe 301 is connected with a filtering box 302. A filtering plate 303 is installed inside the filtering box 302. A hanging ring 304 is installed on the top of the filtering plate 303. A drain pipe 305 is installed near the bottom in the middle on the right side of the filtering box 302. The left end of the outer surface of the water outlet pipe 301 is connected with the inside of the through hole opened in the middle near the bottom on the right side of the desulfurization tower 101. The outer surface of the filtering plate 303 is hermetically and slidably connected with the inner wall of the rectangular through hole opened in the middle of the top surface of the filtering box 302.

[0037] Through the setting of the filtering structure, a plurality of filtering boxes 302 installed inside the filtering box 302 are used to filter and adsorb the solution after spraying, so as to facilitate the filtration of the solution wastewater after the flue gas treatment reaction, facilitate the subsequent treatment of the wastewater, and can effectively filter and treat the mud formed by the dust in the flue gas.

[0038] After the flue gas is desulfurized using a solution, the wastewater enters the interior of the filtration tank 302 through the water outlet pipe 301. Multiple filter plates 303 installed inside the filtration tank 302 are used to filter the wastewater. Thus, the sludge in the wastewater is filtered using the adsorbent fillers filled in the multi-layer filter meshes inside the filter plates 303. When the wastewater is discharged through the drain pipe 305, it is convenient for further treatment. At the same time, the filter plates 303 are hermetically and slidably connected to the rectangular through holes opened at the top of the filtration tank 302, which is also convenient for replacing them to ensure a better filtration effect.
