[0002] Steel furnaces produce a lot of flue gas when casting or smelting iron. The flue gas contains a lot of harmful substances. If the flue gas is not filtered, it will cause strong pollution to the atmosphere. In order to meet the production needs of modern technology, this part of the flue gas must be treated. On the one hand, it can purify the waste gas and reduce pollution to the environment. On the other hand, the waste gas contains a lot of waste heat, which can be recycled to save heat energy.

[0003] Bag dust collectors are heat-resistant and heat-insulating. They filter the flue gas and recover the solid particles in the flue gas to increase production and reduce costs. However, the filtering part of the bag dust collector is usually a one-way ventilation filter structure. The internal filter element is very easy to be blocked when working continuously. In actual work, replacing the filter element requires stopping work and disassembling, which is too cumbersome, so it needs to be improved. Summary of the invention

The torque wheels can rotate under the action of the motor and control the rotation of the dissolving long tube through friction. The inside of the power disk is filled with alkaline solution, and the infusion pump can punch the alkaline solution inside the power disk into the inside of the dissolving long tube.

Compared with general filtering devices, it can avoid the problem of filter element clogging, and during the reaction process, the stirring plate will provide stirring work to make the flue gas react with the alkaline solution as much as possible, thereby avoiding the problem of insufficient flue gas reaction.

[0013] 2. The power disk of the device can recover the alkaline solution inside the long dissolving tube through the reflux pipe, and detect the alkaline solution recovered inside the power disk through the detection components on both sides, so as to judge whether the alkalinity of the solution can continue to undergo a neutralization reaction, thereby avoiding the problem that the alkalinity of the alkaline solution is insufficient and the flue gas cannot be filtered, resulting in a deterioration in the flue gas filtration effect.

[0014] 3. Rotating the modified chassis can make one end of the air pipe passing through the through-hole align with the docking bottom block. On the one hand, it can prevent the smoke from entering the device. On the other hand, it can judge the pressure of the pressurized smoke according to the pressure on the pressure-sensitive element, thereby adjusting the concentration of the alkaline solution added to the dissolving long tube and the rotation rate of the torque wheel to avoid the problem of excessive smoke flow rate and insufficient reaction.

[0015] 4. After the purified gas is dehumidified, the gas content will decrease, so there will be a deviation between the exhaust flow of the exhaust pipe and the intake flow of the air connection pipe. In order to ensure that the device only exhausts and does not absorb gas from the outside, the air connection equipment is improved. Only when the internal air pressure is high can the gas be discharged from the exhaust pipe. Otherwise, the compressed open-hole compression cylinder can prevent the external gas from flowing back from the exhaust pipe to the inside of the dissolving long tube, causing the alkaline solution inside the dissolving long tube to be reacted without reason.

A bent through pipe 36 is fixedly connected to the top of the inner cavity of the infusion pump 35. Pipe holders 32 are symmetrically arranged on both sides of the outer surface of the power disk 31. Detection components 34 are symmetrically arranged on the front and back sides of the upper surface of the power disk 31. The detection component 34 can monitor the pH value of the alkaline solution inside the power disk 31 at all times through the probe at the bottom. Torque wheels 33 are evenly arranged in the middle of the inner wall of the power disk 31. The torque wheels 33 can rotate under the action of the motor. The rotation of the dissolving long tube 21 is controlled by friction. The inside of the power disk 31 is filled with alkaline solution. The infusion pump 35 can punch the alkaline solution inside the power disk 31 into the inside of the dissolving long tube 21.

[0020] The lower surface of the power disk 31 is fixedly connected to the inner wall of the heat-insulating shell 11, the bottom end of the dissolving long tube 21 is fixedly connected to the axis of the bottom of the inner wall of the heat-insulating shell 11, the number of the air-connecting pipes 27 is two, the top end of the air-connecting pipes 27 extends to the outside of the heat-insulating shell 11, the outer surface of the air-connecting pipes 27 is fixedly connected to the inner wall of the pipe holder 32, and the bottom end of the air-connecting pipes 27 is fixedly connected to the bottom of the inner cavity of the dissolving long tube 21. The number of the reflux pipes 26 is two, the top end of the reflux pipes 26 is fixedly connected to the bottom of the inner cavity of the power disk 31, and the bottom end of the reflux pipes 26 extends to the inside of the dissolving long tube 21, the outer surface of the stirring plate 25 is rotatably connected to the inner wall of the dissolving long tube 21, and the top end of the bending pipe 36 is fixedly connected to the inner cavity of the segmented rotating sleeve 22 through the through-hole.

[0021] The modified chassis 6 includes a filling disk shell 61, and through openings 62 are symmetrically opened on the left and right sides of the inner cavity of the filling disk shell 61. The through openings 62 completely penetrate the filling disk shell 61, and the air connecting pipe 27 can completely pass the smoke into the interior of the dissolving long tube 21 through the through openings 62. The front and back sides of the bottom of the inner cavity of the filling disk shell 61 are symmetrically provided with docking bottom blocks 63. The docking bottom block 63 can block the bottom end of the air connecting pipe 27 to prevent the air connecting pipe 27 from passing smoke. The upper surface of the docking bottom block 63 is fixedly connected to a pressure-sensitive element 64 via a spring washer.

[0022] The outer surface of the filling disk shell 61 is rotatably connected to the lower part of the inner cavity of the dissolving long tube 21, and the bottom end of the air receiving duct 27 is plugged into the interior of the filling disk shell 61 through the through hole 62. The top end of the fixed long rod 24 extends to the outside of the dissolving long tube 21, and an air receiving device 4 is provided on the top of the fixed long rod 24, and an exhaust component 5 is provided inside the air receiving device 4.

[0023] The alkaline solution in the power disk 31 is transported to the interior of the segmented rotating sleeve 22 through the infusion pumps 35 on both sides through the bending tube 36, and then the alkaline solution is injected into the dissolving long tube 21 until the alkaline solution fills the dissolving long tube 21.

[0024] The device is used to treat the flue gas discharged from the furnace. The flue gas enters the bottom of the dissolving long tube 21 through the air connecting pipes 27 on both sides, and then flows upward from the bottom of the dissolving long tube 21. During the process, the flue gas passes through the alkaline solution and reacts with the acidic substances and acidic gases in the flue gas.

[0025] When the flue gas flows from bottom to top, the torque wheel 33 in the middle of the power disk 31 controls the long dissolution tube 21 to rotate. Since the internal stirring plate 25 remains relatively stationary, the stirring plate 25 can relatively stir the alkaline solution inside the long dissolution tube 21, so that the flue gas and the alkaline solution can fully react to achieve purification and filtration.

[0026] The filtered flue gas enters the top drying inner cylinder 23 through the segmented rotating sleeve 22, and the moisture in the gas is filtered out, and is discharged in the form of relatively pure gas through the gas receiving equipment 4 and the exhaust component 5.

[0027] After a period of reaction, the solution inside the dissolving long tube 21 will be extracted into the power disk 31 through the reflux pipe 26 for recovery. At this time, the detection component 34 performs pH detection on the solution inside the power disk 31. If it is still alkaline, it means that the neutralization and filtration reaction can continue, otherwise the solution needs to be replaced.

[0028] When changing the solution, press the fixed long rod 24 downwards, at which time the bottom end of the fixed long rod 24 is inserted into the upper surface of the filling disk shell 61, and then twist the filling disk shell 61. At this time, the air receiving duct 27 inserted through the through-hole 62 is inserted into the interior of the docking bottom block 63, and the smoke cannot enter the interior of the dissolving long tube 21. The docking bottom block 63 also squeezes the pressure-sensitive element 64 due to the air pressure.

[0029] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of embodiment 1, the air receiving device 4 includes a protective top shell 41, the inner wall of the protective top shell 41 is evenly provided with exhaust pipes 42, and spring sleeves 43 are symmetrically provided on the upper and lower sides of the axis of the inner wall of the protective top shell 41. The spring sleeve 43 can only be compressed and deformed up and down, and one end of the spring sleeve 43 away from the inner wall of the protective top shell 41 is fixedly connected with a circular cover plate 44, and the inner cavity of the circular cover plate 44 is fixedly connected with an open hole compression cylinder 45, and air-permeable mesh holes are evenly provided at the folding points of the open hole compression cylinder 45, and as the open hole compression cylinder 45 is stretched, the mesh holes will also expand.

[0030] The top end of the drying inner cylinder 23 is rotatably connected to the axis of the lower surface of the protective top shell 41, the outer surface of the protective top shell 41 is fixedly connected to the top of the inner cavity of the heat-insulating outer shell 11, the top end of the exhaust duct 42 extends to the outside of the heat-insulating outer shell 11, and the outer surface of the fixed long rod 24 is slidably connected to the axis of the inner cavity of the top circular cover plate 44.

[0031] The exhaust component 5 includes a filling inner disk 51, and blade wheels 54 are evenly arranged on the lower surface of the filling inner disk 51. Sliding grooves 52 are evenly opened at the axis of the inner cavity of the filling inner disk 51, and spring pressure plates 53 are evenly arranged in the inner cavity of the filling inner disk 51 through the sliding grooves 52. When the airflow passes through the mesh holes of the open-hole compression cylinder 45 and enters the exhaust duct 42, the blade wheel 54 is driven to rotate, and then the blade wheel 54 measures the flow rate of the airflow according to the rotation speed and feeds it back to the filling inner disk 51.

[0032] There are two filling inner disks 51, the outer surface of the spring pressure plate 53 is slidably connected to the inner wall of the sliding groove 52, and the side of the spring pressure plate 53 away from the sliding groove 52 is pressed against the outer surface of the circular cover plate 44, both ends of the blade wheel 54 are fixedly connected to the inner cavity of the filling inner disk 51 through built-in guide rods, and the outer surface of the filling inner disk 51 is fixedly connected to one side of the inner wall of the protective top shell 41.

[0033] The high-temperature gas that passes through the drying inner cylinder 23 will be filled into the interior of the open-pored compression cylinder 45 through the spring sleeve 43 at the bottom, and discharged from the holes of the open-pored compression cylinder 45 to the exhaust duct 42. If the air pressure filled into the open-pored compression cylinder 45 is relatively high, the circular cover plates 44 on the upper and lower sides will be pushed open, and then the open-pored compression cylinder 45 will be stretched, and the opening of the open-pored compression cylinder 45 will be expanded.

[0034] After the circular cover plate 44 is pushed open, it will push the spring pressure plate 53 on the corresponding side, and then the spring pressure plate 53 begins to accumulate spring potential energy so as to be able to push the circular cover plate 44 back to its original position. When the purified flue gas enters the exhaust duct 42, the airflow will push the blade wheel 54, and at this time the blade wheel 54 rotates, and the flow rate of the exhaust gas from the exhaust duct 42 is determined according to the rotation speed of the blade wheel 54.

[0035] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
