[0002] In the field of environmental technology and industrial emission treatment, magnesium oxide desulfurization is a widely used method, especially when dealing with sulfur dioxide in the flue gas of coal-fired power plants and other industrial facilities. The method works by reacting sulfur dioxide in the flue gas with magnesium oxide to produce magnesium sulfate. This process is usually carried out in a desulfurization tower, where a magnesium oxide solution is sprayed into the flue gas stream to react chemically with sulfur dioxide;

[0003] The invention patent application with the publication number "CN107469603A" discloses a desulfurization device using the magnesium oxide method, which has a simple design structure, convenient operation, energy saving and cost saving, mild process conditions, relatively loose requirements on equipment, and convenient operation. It can solve the shortcomings of the original high-temperature calcination of sub-gram magnesium sulfate, recovery of high-concentration sulfur dioxide, and production of sulfuric acid, such as large investment, high energy consumption, harsh equipment requirements, strict operating conditions, and serious secondary pollution, which is conducive to reducing enterprise costs and improving environmental quality;

[0004] However, this method has certain problems. The most important problem is that the generated magnesium sulfate will cause serious corrosion to the internal structure of the desulfurization tower. Since the desulfurization tower is usually designed as a fixed structure to withstand continuous and long-term operation, its materials and design must be able to withstand high concentrations of acidic substances. Over time, the inner wall of the desulfurization tower will gradually be corroded, which not only affects the desulfurization efficiency, but may also cause equipment damage, increase maintenance costs and equipment downtime, thereby affecting the overall economic benefits and safe operation of the facility.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0036] The following describes the desulfurization device using the magnesium oxide method and the method of use according to the embodiment of the present application in conjunction with the accompanying drawings.

[0037] The embodiment of the present application provides a desulfurization device utilizing a magnesium oxide method, which can solve the problem that magnesium sulfate may cause serious corrosion to the internal structure of the desulfurization tower. Since the desulfurization tower is usually designed as a fixed structure to withstand continuous and long-term operation, its materials and design must be able to resist high concentrations of acidic substances. Over time, the inner wall of the desulfurization tower will gradually be corroded, which not only affects the desulfurization efficiency, but may also cause equipment damage, increase maintenance costs and equipment downtime, thereby affecting the overall economic benefits and safe operation of the facility.

[0039] The magnesium oxide desulfurization and anti-corrosion mechanism 6 includes a driving motor 61 , a driving head 62 , a connecting arm 63 , a waste liquid bin 64 , a set component 65 and a desulfurization flushing component 66 .

[0040] The driving motor 61 is installed on the top of the assembly base 1 , the driving head 62 is rotatably connected to the top center of the operating table 3 , and the output end of the driving motor 61 is fixedly connected to the bottom of the driving head 62 .

[0041] It should be noted that a protective sleeve is fixedly connected to the top of the operating table 3 described in this embodiment, and the protective sleeve is rotatably sleeved on the outer wall of the driving head 62 .

[0042] A plurality of waste liquid bins 64 are slidably connected to the top eccentric position of the operating table 3 in a circular array through a sliding base 641 , and a connecting arm 63 is provided between the outer wall of the waste liquid bin 64 and the driving head 62 , and they are connected through the connecting arm 63 .

[0043] Further, such as Figure 1 As shown, a guide groove 31 for the sliding base 641 to slide is provided on the top of the operating platform 3.

[0044] It should be noted that a block matching the guide groove 31 is fixedly connected to the bottom of the sliding base 641 described in this embodiment.

[0045] Further, such as Figure 1 As shown, a drain head 642 is fixedly connected to the bottom of the waste liquid bin 64 , and a solenoid valve is installed on the drain head 642 . A reinforcing sleeve 643 is fixedly sleeved on the outer wall of the waste liquid bin 64 , and the outer wall of the reinforcing sleeve 643 is fixedly connected to one end of the connecting arm 63 .

[0046] It should be noted that a detachable inner liner can be installed inside the waste liquid bin 64 described in this embodiment, and the top of the inner liner is fixedly connected with a flange, and the bottom of the flange is snapped onto the top of the waste liquid bin 64. At the same time, the bottom of the inner liner is fixedly connected with a threaded head, and a threaded groove begins to form at the bottom inner side of the waste liquid bin 64, which makes it easy to disassemble and assemble the inner liner, thereby facilitating removal and flushing, thereby avoiding corrosion problems caused by long-term use.

[0047] As a possible situation, the end of the drain head 642 may be connected to a drain pipe, and the waste liquid may be collected centrally through the drain pipe.

[0048] There are multiple sets of set components 65, which are installed in a circular array on the mounting top plate 5, and the number of the set components 65 is the same as the number of the waste liquid bins 64.

[0049] It should be noted that the positions of the multiple set components 65 and the waste liquid bin 64 described in this embodiment correspond one to one and are located on the same vertical line.

[0050] The desulfurization flushing assembly 66 is installed on the assembly base 1, and the desulfurization flushing assembly 66 is connected to a plurality of set assemblies 65.

[0051] It should be noted that the desulfurization flushing assembly 66 described in this embodiment is provided with a desulfurization spray end and a flushing spray end, and the desulfurization spray end is located at the bottom of the flushing spray end, so that after desulfurization, effective flushing can be performed.

[0052] The exhaust assembly 7 is installed on the top of the mounting top plate 5 , and the exhaust assembly 7 is connected to the set assembly 65 .

[0053] It should be noted that the end of the exhaust assembly 7 described in this embodiment can extract the desulfurized gas and carry out subsequent further processing. For example, spraying may introduce droplets and solid particles into the exhaust gas, so it is usually necessary to remove these particles through a bag filter or an electrostatic precipitator. This step can effectively reduce the suspended particulate matter in the exhaust gas, thereby preventing them from being discharged into the atmosphere.

[0054] Specifically, when using the magnesium oxide method for desulfurization, the drive motor 61 is installed on the top of the assembly base 1, the drive head 62 is rotatably connected to the top center of the operating table 3, the output end of the drive motor 61 is fixedly connected to the bottom of the drive head 62, and multiple waste liquid bins 64 are slidably connected to the top eccentric position of the operating table 3 through the sliding base 641 in a circular array. A connecting arm 63 is provided between the outer wall of the waste liquid bin 64 and the drive head 62, and they are connected through the connecting arm 63. The set components 65 are provided with multiple groups, and the multiple sets of set components 65 are in a circular array. The desulfurization flushing assembly 66 is installed on the mounting top plate 5, and the number of the set components 65 is the same as the number of the waste liquid bins 64. The desulfurization flushing assembly 66 is installed on the assembly base 1, and the desulfurization flushing assembly 66 is connected to multiple set components 65, and then the waste gas is injected into the position of one of the set components 65 and moved to make it mutually engaged with the top of one of the waste liquid bins 64, and a sealed environment is formed inside, and then the waste gas is injected into the inside of this set component 65, and then the desulfurization spray end in the desulfurization flushing assembly 66 is started, and the slurry mixed with magnesium oxide and water can be sprayed onto the set component. Inside the suit assembly 65, the exhaust gas contacts the slurry from bottom to top to achieve desulfurization, and then the desulfurized gas is discharged through the exhaust assembly 7. After working for a certain period of time, the gas injection is stopped, and then the newly used suit assembly 65 is lifted, and then the drive motor 61 is started to drive the support arm 2 to rotate, so that the used waste liquid bin 64 is moved to the bottom of the unused suit assembly 65, and then the exhaust gas is injected into the unused suit assembly 65 to perform the desulfurization operation, and the previously used suit assembly 65 is moved to the top of another waste liquid bin 64, and then the flushing end of the desulfurization flushing assembly 66 is started, and the flushing liquid can be sprayed into the inside of the used suit assembly 65, so as to flush the inside thereof, avoiding the occurrence of corrosion problems caused by untimely flushing after use, and extending the service life. At the same time, the desulfurization operation is carried out synchronously through the new suit assembly 65, and the desulfurization operation is not delayed, thereby avoiding the gradual corrosion of the inner wall of the desulfurization tower, which not only affects the desulfurization efficiency, but also may cause equipment damage, increase maintenance costs and equipment downtime, thereby affecting the overall economic benefits and safe operation of the facility.

[0055] In order to clearly illustrate the above embodiment, in an example of the present application, Figures 1 to 8 As shown, the set assembly 65 includes a hydraulic cylinder 651, a driving rod 652, an assembly plate 653 and a sealing chamber 654. The hydraulic cylinder 651 is installed on the top of the mounting top plate 5, and the output end of the hydraulic cylinder 651 slides through the top of the mounting top plate 5 and is fixedly connected to one end of the driving rod 652. The top of the assembly plate 653 is fixedly connected to the other end of the driving rod 652, and the top of the sealing chamber 654 is fixedly connected to the bottom of the assembly plate 653.

[0056] It should be noted that a detachable inner liner may be installed inside the sealing chamber 654 described in this embodiment, and its assembly method is the same as that of the inner liner in the waste liquid chamber 64.

[0057] Further, such as Figure 1 As shown, the outer wall of the sealing chamber 654 is fixedly sleeved with a snap-fit ​​sleeve plate 6541 , and the outer wall at the end of the sealing chamber 654 is in contact with the inner wall of the waste liquid chamber 64 .

[0058] Specifically, in order to avoid corrosion of the inner wall of the desulfurization chamber used for desulfurization due to long-term use, the hydraulic cylinder 651 is installed on the top of the mounting top plate 5, and the output end of the hydraulic cylinder 651 slides through the top of the mounting top plate 5 and is fixedly connected to one end of the driving rod 652. The top of the assembly plate 653 is fixedly connected to the other end of the driving rod 652, and the top of the sealing chamber 654 is fixedly connected to the bottom of the assembly plate 653. Then, by starting the hydraulic cylinder 651, the sealing chamber 654 can be driven to rise or fall, so that it can be connected or disconnected with multiple waste liquid chambers 64. In this way, the used sealing chamber 654 can be connected to one of the waste liquid chambers 64, and then the inner wall of the sealing chamber 654 can be flushed by spraying the flushing liquid, so as to avoid corrosion and extend the service life.

[0059] Another beneficial effect of this embodiment is that, through the replaceable operation of the sealing chamber 654, when one of the sealing chambers 654 is flushed, the exhaust gas can pass through the other sealing chamber 654 for exhaust gas desulfurization operation, thereby achieving work continuity and improving work efficiency.

[0060] In one example of the present application, Figures 1 to 8 As shown, the desulfurization flushing assembly 66 includes a slurry bin 661, a water collecting bin 662, a pump body 663, a support rod 664, a liquid separator 665, a connector 666, a spray sleeve 667 and a connecting hose 668. The slurry bin 661 and the water collecting bin 662 are symmetrically installed on the top of the assembly base 1. Two pump bodies 663 are provided and symmetrically installed on the top of the assembly base 1. The two pump bodies 663 and the slurry bin 661 and the water collecting bin 662 are staggered on the assembly base 1. There are two pump bodies 663 and the slurry bin 661 and the water collecting bin 662. There is a connecting pipe 6631, and they are connected through the connecting pipe 6631. One end of the support rod 664 is fixedly connected to the bottom center of the mounting top plate 5. Two liquid separation heads 665 are provided, which are respectively fixedly sleeved on the other end of the support rod 664. The outer wall of each sealing chamber 654 is fixedly sleeved with two spray sleeves 667. One end of a plurality of connecting heads 666 is fixedly connected to the outer wall of the liquid separation head 665 in a circular array. A connecting hose 668 is provided between the connecting head 666 and the spray sleeve 667, and they are connected through the connecting hose 668.

[0061] Further, such as Figure 1 As shown, the inner wall of the spray sleeve 667 is fixedly connected with multiple spray heads in a circular array, and the ends of the spray heads pass through the inner wall of the sealing chamber 654. The outer wall of the sealing chamber 654 is fixedly connected with a gas injection pipeline, and a valve body 6661 is installed on the connecting head 666.

[0062] It should be noted that the tops of the slurry bin 661 and the water collection bin 662 described in this embodiment are both equipped with liquid injection ports, and a stirring device is installed inside the slurry bin 661, so that the magnesium oxide and water are mixed more evenly, thereby improving the desulfurization effect.

[0063] Specifically, in order to ensure that the desulfurization operation and the flushing operation can be carried out synchronously, a connecting pipe 6631 is provided between the pump body 663 and the slurry bin 661 and the water collecting bin 662, and they are connected through the connecting pipe 6631. One end of the support rod 664 is fixedly connected to the bottom center of the mounting top plate 5. Two liquid separators 665 are provided, which are respectively fixedly sleeved on the other end of the support rod 664. Two spray sleeves 667 are fixedly sleeved on the outer wall of each sealed bin 654. One end of a plurality of connecting heads 666 is fixedly connected to the outer wall of the liquid separator 665 in a circular array. A connecting hose 668 is provided between the connecting head 666 and the spray sleeve 667, and they are connected through the connecting hose 668. Then, through the two liquid separators 665, slurry and flushing liquid can be respectively transported. At the same time, through the valve body 6661 on the connecting head 666, the slurry or flushing liquid can be stably transported to the inside of the corresponding sealed bin 654, thereby realizing the synchronous desulfurization and flushing, and effectively improving the work efficiency.

[0064] Another beneficial effect of this embodiment is that since the slurry and the flushing liquid are respectively transported through the corresponding connecting hoses 668, the stability of the transportation can be improved, and the risk of liquid leakage is reduced, thereby improving the safety of the operation process. At the same time, the inner wall of the sealed chamber 654 after use can be promptly flushed through the spray sleeve 667, which effectively reduces corrosion.

[0065] In one example of the present application, Figures 1 to 8 As shown, the exhaust assembly 7 includes a fan 71, an exhaust pipe 72, a collecting head 73 and an air supply pipe 74. The fan 71 is installed at the top center of the mounting top plate 5. The collecting head 73 is fixedly sleeved on the end of the support rod 664. An air supply pipe 74 is provided between the sealing chamber 654 and the collecting head 73, and they are connected through the air supply pipe 74. One end of the exhaust pipe 72 is fixedly connected to the exhaust end of the fan 71.

[0066] It should be noted that a ventilation groove is provided on the top of the support rod 664 described in this embodiment for connecting with the air inlet end of the fan 71 and the exhaust end of the collecting head 73 .

[0067] Specifically, after the desulfurization of the exhaust gas, in order to discharge the exhaust gas in time, the fan 71 is installed at the top center of the mounting top plate 5, the collecting head 73 is fixedly sleeved on the end of the support rod 664, and a gas pipeline 74 is provided between the sealing chamber 654 and the collecting head 73, and they are connected through the gas pipeline 74. One end of the exhaust pipeline 72 is fixedly connected to the exhaust end of the fan 71, and then the fan 71 is started to conveniently extract the desulfurized gas in the sealing chamber 654 and discharge it through the exhaust pipeline 72. The outlet end of the exhaust pipeline 72 can be connected to other subsequent processing equipment to further purify the gas.

[0068] Another beneficial effect of this embodiment is that the gas in the sealed chamber 654 is extracted using the fan 71, ensuring that the gas after desulfurization treatment can be quickly and effectively removed from the reaction area, reducing the residence time of the gas in the equipment, thereby reducing possible secondary pollution of the gas or corrosion to the equipment.

[0069] A method for using a magnesium oxide desulfurization device comprises the following steps:

[0070] S1, preparation stage: Mix magnesium oxide powder and water to prepare slurry, and store it in the slurry bin 661, prepare enough flushing liquid, and store it in the water collection bin 662;

[0071] S2. Connection and start: Slidingly connect the waste liquid bin 64 and a set of set components 65 to ensure a firm connection, start the pump body 663, spray the slurry into the sealed bin 654, inject the waste gas into the sealed bin 654, and the waste gas contacts the slurry from bottom to top to achieve desulfurization;

[0072] S3, switching and cleaning.
