Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization devices, and in particular to a high-efficiency and energy-saving multi-stage desulfurization device and a use method thereof. Background Art

[0002] The desulfurization device is a device that absorbs sulfur dioxide in industrial waste gas. The cost of wet desulfurization devices is high, while the cost of dry desulfurization devices is low. Some dry desulfurization devices use lime powder to react with sulfur dioxide in high-temperature waste gas. The lime powder needs to be sprayed out continuously, wasting electricity.

[0003] The defects of the existing desulfurization device are:

[0004] 1. Prior art US07455819B2 discloses a simultaneous dry desulfurization / denitrification device. This technology requires continuous injection of reactants. Continuous injection of reactants requires continuous operation of the injection components, which wastes electrical energy. Therefore, a high-efficiency and energy-saving multi-stage desulfurization device that does not require continuous injection of reactants and saves electrical energy is needed to solve this problem.

[0005] 2. The prior art JPS5228461A discloses a dry desulfurization device. In the case of a dust filtering component being set up, it is inconvenient to replace the filter component after filtering the dust in the exhaust gas after absorbing sulfur dioxide, and replacing the filter component is a waste of time. Therefore, a high-efficiency and energy-saving multi-stage desulfurization device with a filter component that is easy to replace is needed to solve this problem.

[0006] 3. Prior art JP2012223668A discloses a method and device for dry desulfurization. This technology does not have a structure for assisting the replacement of lime. In a multi-stage filtration structure, lime is generally arranged in layers from bottom to top to facilitate the uniform distribution of lime. When replacing lime at a high position, the loading and unloading of lime is troublesome. Therefore, an efficient and energy-saving multi-stage desulfurization device with an auxiliary lime replacement structure is needed to solve this problem.

[0007] 4. Prior art CN110215820B discloses a novel and highly efficient semi-dry multi-stage desulfurization device and working method. This technology does not have a counterweight structure. When a structure for lifting and transporting goods is provided, the weight of the goods can easily cause pressure on the structure for transporting goods, causing the structure for transporting goods to be subjected to unbalanced force and thus bend or break. Therefore, a highly efficient and energy-saving multi-stage desulfurization device having a material transporting structure with a counterweight structure is needed to solve this problem.

[0059] The method of using the high-efficiency and energy-saving multi-stage desulfurization device is as follows:

[0060] S1. Add lime powder into the frame 15, and then use the hydraulic expansion unit 20 to drive the frame 15 completely into the desulfurization box 1;

[0061] S2, the exhaust gas containing sulfur dioxide is passed into the desulfurization box 1 through the hand valve 2, and the exhaust gas passes through the lime in the multi-stage frame 15 from bottom to top, and the sulfur dioxide reacts with the lime, thereby the sulfur dioxide is absorbed by the reaction;

[0062] S3, the exhaust gas passes through the frame 15, enters the box body 6 through the gas flow metering unit 4 and the metal hose 5, and then passes through the filter cloth 13 to filter the dust and is discharged from the output pipe 2 8;

[0063] S4, when the gas flow in the gas flow metering unit 4 is reduced to the set value, the motor 16 drives the stirring rod 18 to rotate, so that the agglomerated lime is broken up to prevent the agglomerated lime from affecting the flow of exhaust gas;

[0064] S5. When the sulfur dioxide sensor unit 41 detects sulfur dioxide, the solenoid valve 42 is closed;

[0065] S6, put new lime into the upper plate frame 37, then the hydraulic expansion unit 28 drives the plate frame 37 to move upward, and then the hydraulic expansion unit 1 20 drives the frame 15 to move to the upper and lower plate frames 37;

[0066] S7, move the grid baffle 19 on the frame 15 forward to make the lime in the frame 15 fall into the plate frame 37 below, and then move the baffle 2 39 in the upper plate frame 37 forward to make the lime in the upper plate frame 37 fall into the frame 15.

[0068] S71. When lime is loaded in the plate frame 37, the counterweight frame 35 is driven to move to the other side of the plate frame 37 by the hydraulic expansion unit 33, so as to balance the pressure on one side of the plate frame 37 and avoid bending of the piston rod 29.

[0069] Working principle: Before using the high-efficiency and energy-saving multi-stage desulfurization device, you should first check whether there are any problems that affect the use of the high-efficiency and energy-saving multi-stage desulfurization device, add lime powder into the frame 15, and then use the hydraulic telescopic unit 20 to drive the frame 15 completely into the desulfurization box 1, and pass the exhaust gas containing sulfur dioxide into the desulfurization box 1 from the hand valve 2. The exhaust gas passes through the lime in the multi-stage frame 15 from bottom to top, and sulfur dioxide reacts with the lime, thereby absorbing the sulfur dioxide reaction. After passing through the frame 15, the exhaust gas enters the box body 6 through the gas flow metering unit 4 and the metal hose 5, and then passes through the filter cloth 13 to filter the dust and is discharged from the output pipe 2 8. When the gas flow in the gas flow metering unit 4 is reduced to the set value, the motor 16 drives the stirring rod 18 to rotate, so that the agglomerated lime is broken to avoid agglomeration. Lime affects the flow of exhaust gas. When the sulfur dioxide sensor unit 41 detects sulfur dioxide, the solenoid valve 42 is closed, and then new lime is placed in the upper plate frame 37. Then the hydraulic telescopic unit 28 drives the plate frame 37 to move upward, and then the hydraulic telescopic unit 20 drives the frame 15 to move to the upper and lower plate frames 37, and the grid baffle 19 on the frame 15 is moved forward to make the lime in the frame 15 fall into the lower plate frame 37. Then, by moving the baffle 2 39 in the upper plate frame 37 forward, the lime in the upper plate frame 37 falls into the frame 15. When the plate frame 37 is filled with lime, the counterweight frame 35 is driven to move to the other side of the plate frame 37 by the hydraulic telescopic unit 33, thereby balancing the pressure on one side of the plate frame 37 and avoiding bending of the piston rod 29.
