Description

Technical Field

[0001] This solution belongs to the field of desulfurization and denitrification technology, specifically involving a desulfurization and denitrification device for smelting flue gas. Background Technology

[0002] Utility model patent CN222969542U discloses a flue gas desulfurization and denitrification device, relating to the field of flue gas treatment. This utility model's flue gas desulfurization and denitrification device, through its diversion-type convenient cleaning water storage tank, includes a support base, a primary water storage tank, a secondary water storage tank, a three-way connecting pipe, a cleaning water detector, a diversion box, a conical guide plate, and an electromagnetic diversion valve. During use, the treated water can be replaced without shutting down the equipment, achieving both good working efficiency and ensuring the treatment effect of the treated water. The self-separating flue gas inlet box includes a flue gas separation shell, an inlet pipe, a support frame, a flue gas dispersion column, a flue gas connecting pipe, and a conical drainage cover. During use, this ensures the uniformity of flue gas release, allowing for repeated contact with the treated water, while preventing treated water from entering the flue pipe. This device is not only simple in structure but also easy to operate, offering promising application prospects.

[0003] However, the device has certain shortcomings in use. When the flue gas enters the alkaline solution, the flue gas and the aqueous solution cannot mix and react quickly, resulting in insufficient contact between some flue gas and the solution, which leads to insufficient flue gas reaction and incomplete desulfurization and denitrification. At the same time, some solid particles generated by the acid-base reaction inside the device will accumulate and adhere inside the device, making it difficult to clean the device later. Utility Model Content

[0004] The purpose of this solution is to provide a desulfurization and denitrification device for smelting flue gas, in order to solve the problem that when flue gas enters an alkaline solution, the flue gas and the aqueous solution cannot mix and react quickly, resulting in insufficient contact between some flue gas and the solution, and thus insufficient flue gas reaction, resulting in incomplete desulfurization and denitrification. At the same time, some solid particles generated by the acid-base reaction inside the device will accumulate and adhere inside the device, making it difficult to clean the device later.

[0005] To achieve the above objectives, this solution provides a desulfurization and denitrification device for smelting flue gas, including a reaction tank. A motor is fixedly installed at the lower middle part of the reaction tank. The motor's shaft passes through the reaction tank and is rotatably connected to it. A mixing mechanism is provided on the motor's shaft. A connecting rod is fixedly connected to the surface of the motor's shaft. A scraper is fixedly connected to the end of the connecting rod. The scraper contacts the inner side of the reaction tank wall. An alkaline water pipe, an exhaust gas pipe, and a liquid outlet pipe are fixedly connected inside the reaction tank.

[0006] The principle of this solution is as follows: During use, alkaline water is introduced into the reaction tank through the alkaline water pipe, and waste gas is introduced into the distribution cylinder through the waste gas pipe. The waste gas is discharged through the perforated tube into the distribution cylinder. The motor is started, and the motor drives the square rod to rotate, which in turn drives the distribution cylinder to rotate. The distribution cylinder drives the inclined block to move. After the inclined block moves and contacts the trapezoidal block, it is misaligned. This process causes the distribution cylinder to move up and down under the extension and contraction of the spring. The motor drives the square rod to rotate, which in turn causes the distribution cylinder to rotate. Through the periodic engagement and disengagement between the inclined block and the trapezoidal block, the distribution cylinder moves up and down. This allows the perforated tube to move up and down synchronously during rotation, introducing waste gas into the alkaline water inside the reaction tank. This makes the mixing of waste gas and alkaline water more efficient and uniform, and the desulfurization and denitrification more efficient. The motor shaft drives the connecting rod to rotate, which in turn drives the scraper to rotate. This scrapes the inner wall and bottom of the reaction tank, preventing the solids produced by the reaction from adhering to the inside of the reaction tank, which would make cleaning the reaction tank more troublesome later.

[0007] The technical advantage of this solution is that the motor drives the connecting rod to rotate the scraper, which scrapes the inner wall of the reaction vessel. This scrapes the inner wall and bottom of the reaction vessel, preventing solids produced by the reaction from adhering to the inside of the reaction vessel and causing trouble in cleaning the reaction vessel later.

[0008] The motor drives the square rod to rotate, which in turn causes the diverter to rotate. The periodic engagement and disengagement between the inclined block and the trapezoidal block causes the diverter to move up and down. This allows the hollow tube to move up and down synchronously during rotation, allowing the waste gas to enter the alkaline water inside the reaction tank. This makes the mixing of waste gas and alkaline water more efficient and uniform, and the desulfurization and denitrification more efficient.

[0009] Furthermore, a reinforcing rib is fixedly connected to the surface of the connecting rod, and the reinforcing rib is fixedly connected to the scraper. By setting the reinforcing rib, the support stability of the scraper is increased.

[0010] Furthermore, the mixing mechanism includes a square rod, which is fixedly connected to the upper end of the motor shaft. A diverter cylinder is slidably connected to the outer side of the square rod. A baffle is fixedly connected to the upper end of the square rod, and a spring is provided on the outer side of the square rod. A hollow tube is fixedly connected inside the diverter cylinder, and an annular groove is formed inside the diverter cylinder. The annular groove is slidably connected to the exhaust gas pipe, and an inclined block is fixedly connected to the outer side of the diverter cylinder. The square rod is driven to rotate by the motor, which in turn causes the diverter cylinder to rotate. Through the periodic engagement and disengagement between the inclined block and the trapezoidal block, the diverter cylinder moves up and down. This allows the hollow tube to move up and down synchronously during rotation, allowing the exhaust gas to enter the alkaline water inside the reaction tank. This makes the mixing of exhaust gas and alkaline water more efficient and uniform, and the desulfurization and denitrification more efficient.

[0011] Furthermore, one end of the spring is fixedly connected to the diverter cylinder, and the other end of the spring is fixedly connected to the baffle. By incorporating the spring, the diverter cylinder can be easily reset.

[0012] Furthermore, the interior of the flow divider is provided with vent holes, which are connected to the annular groove. The vent holes ensure communication between the annular groove and the inner cavity of the flow divider.

[0013] Furthermore, a baffle is fixedly connected to the outside of the exhaust pipe, and the baffle is rotatably connected to the diverter cylinder. The baffle seals the annular groove.

[0014] Furthermore, a trapezoidal block is fixedly connected inside the reaction vessel, and the trapezoidal block contacts an inclined block. By configuring the trapezoidal block and the inclined block to cooperate, the flow divider can move up and down. Attached Figure Description

Detailed Implementation

[0017] The implementation examples are basically as follows Figure 1 , Figure 2As shown, this embodiment provides a desulfurization and denitrification device for smelting flue gas, including a reaction tank 1. A motor 2 is fixedly installed at the lower middle part of the reaction tank 1. The rotating shaft of the motor 2 passes through the reaction tank 1 and is rotatably connected to the reaction tank 1. A mixing mechanism 3 is provided on the rotating shaft of the motor 2. A connecting rod 4 is fixedly connected to the surface of the rotating shaft of the motor 2. A scraper 5 is fixedly connected to the end of the connecting rod 4. The scraper 5 contacts the inner side of the tank wall of the reaction tank 1. A reinforcing rib 6 is fixedly connected to the surface of the connecting rod 4. The reinforcing rib 6 is fixedly connected to the scraper 5. By setting the reinforcing rib 6, the support stability of the scraper 5 is increased. An alkaline water pipe 7 is fixedly connected inside the reaction tank 1. An exhaust gas pipe 8 is fixedly connected inside the reaction tank 1. An outlet pipe 9 is fixedly connected inside the reaction tank 1.

[0018] like Figure 2 , Figure 3 , Figure 4 As shown, the mixing mechanism 3 includes a square rod 31. The upper end of the motor 2's rotating shaft is fixedly connected to the square rod 31. A diverter cylinder 32 is slidably connected to the outer side of the square rod 31. A baffle 33 is fixedly connected to the upper end of the square rod 31. A spring 34 is provided on the outer side of the square rod 31. One end of the spring 34 is fixedly connected to the diverter cylinder 32, and the other end of the spring 34 is fixedly connected to the baffle 33. By providing the spring 34, the diverter cylinder 32 can be easily reset. A hollow tube 35 is fixedly connected inside the diverter cylinder 32. An annular groove 36 is opened inside the diverter cylinder 32. The annular groove 36 is slidably connected to the exhaust pipe 8. A vent hole is opened inside the diverter cylinder 32. The vent hole communicates with the annular groove 36. By providing the vent hole, the annular groove 36 and the inner cavity of the diverter cylinder 32 are connected. The outer side of the exhaust pipe 8... A baffle 37 is fixedly connected to the side, and the baffle 37 is rotatably connected to the diverter 32. By setting the baffle 37, the annular groove 36 is closed. An inclined block 38 is fixedly connected to the outside of the diverter 32, and a trapezoidal block 39 is fixedly connected to the inside of the reaction tank 1. The trapezoidal block 39 and the inclined block 38 are in contact. By setting the trapezoidal block 39 and the inclined block 38 to cooperate, the diverter 32 can move up and down. The square rod 31 is driven to rotate by the motor 2, which in turn causes the diverter 32 to rotate. The periodic engagement and disengagement between the inclined block 38 and the trapezoidal block 39 causes the diverter 32 to move up and down. This allows the hollow tube 35 to move up and down synchronously during the rotation, allowing the waste gas to enter the alkaline water inside the reaction tank 1. This makes the mixing of waste gas and alkaline water more efficient and uniform, and the desulfurization and denitrification more efficient.

[0019] The specific implementation process of this utility model is as follows: In use, alkaline water is introduced into the reaction tank 1 through the alkaline water pipe 7, and waste gas is introduced into the diversion cylinder 32 through the waste gas pipe 8. The waste gas is discharged through the diversion cylinder 32 into the hollow tube 35. The motor 2 is started, and the motor 2 drives the square rod 31 to rotate. The square rod 31 drives the diversion cylinder 32 to rotate, and the diversion cylinder 32 drives the inclined block 38 to move. After the inclined block 38 moves and contacts the trapezoidal block 39, it is misaligned. This process causes the diversion cylinder 32 to drive the hollow tube 35 to move up and down under the extension and contraction of the spring 34. The motor 2 drives the square rod 31 to rotate, thereby diverting the flow. The cylinder 32 rotates, and through the periodic engagement and disengagement between the inclined block 38 and the trapezoidal block 39, the diversion cylinder 32 moves up and down, which in turn allows the hollow tube 35 to move up and down synchronously during rotation, allowing the waste gas to enter the alkaline water inside the reaction tank 1. This makes the mixing of waste gas and alkaline water more efficient and uniform, and the desulfurization and denitrification more efficient. The rotating shaft of the motor 2 drives the connecting rod 4 to rotate, and the connecting rod 4 drives the scraper 5 to rotate, scraping the inner wall of the reaction tank 1. This scrapes the inner wall and bottom of the reaction tank 1, preventing the solids produced by the reaction from adhering to the inside of the reaction tank 1, which would make cleaning the reaction tank 1 troublesome later.

[0020] The motor 2 drives the connecting rod 4 to rotate the scraper 5, which scrapes the inner wall of the reaction tank 1. This scrapes the inner wall and bottom of the reaction tank 1, preventing the solids produced by the reaction from adhering to the inside of the reaction tank 1, which would make cleaning the reaction tank 1 troublesome later.

[0021] The motor 2 drives the square rod 31 to rotate, which in turn causes the diversion cylinder 32 to rotate. The periodic engagement and disengagement between the inclined block 38 and the trapezoidal block 39 causes the diversion cylinder 32 to move up and down. This allows the hollow tube 35 to move up and down synchronously during rotation, allowing the waste gas to enter the alkaline water inside the reaction tank 1. This makes the mixing of waste gas and alkaline water more efficient and uniform, and the desulfurization and denitrification more efficient.
