Description

Technical Field

[0001] The utility model relates to the technical field of demisters, and particularly relates to a device for separating the flushing liquid of a demister. Background Art

[0002] A demister mainly consists of fixed devices such as corrugated blades, plates, and clamping strips, and is used for wet desulfurization. During the operation of the absorption tower, "fog" with a particle size of 10 - 60 microns is easily generated. The "fog" not only contains moisture, but also dissolves sulfuric acid, sulfates, sulfur dioxide, etc. At the same time, it also causes fouling and serious corrosion of the fan, heat exchanger, and flue. Therefore, the wet desulfurization process requires the absorption equipment to remove fog. The gas to be purified needs to be defogged before leaving the absorption tower. The demister nozzle is one of the main components of the demisting system. The demister nozzle is mainly made of high-quality plastic, has extremely high wear resistance, and a long service life. The demister is an important component of the desulfurization tower. The function of the demister is to capture the fog particles and slurry droplets entrained in the flue gas during the spray absorption process. The efficiency of the demister is not only related to its own structure, but also related to the specific gravity and particle size of the fog particles. The atomization particle size of the nozzle is related to the viscosity of the absorption liquid, the spray pressure, and the nozzle structure. Only by matching the performance of the demister with the particle diameter of the fog particles can a good demisting effect be achieved. If the demisting is not good, the flue gas entraining slurry will be carried to downstream equipment such as flue gas heaters, induced draft fans, and flues, which will cause blockage, severe vibration of the induced draft fan, severe corrosion and scaling of the flue, etc., and thus forced shutdown.

[0003] Therefore, the traditional demister of the desulfurization tower cannot meet people's needs, and it has the following defects: First, there is no designed flushing liquid separation device. During use, the flushing water of the demister and the corresponding circulating spray are not separately designed, and they share the same water source. When in use, it greatly reduces the spray intensity and demisting effect of the demister. At the same time, the flushing water is mixed with the slurry, which is not conducive to stabilizing the concentration and water volume balance of the slurry, and has a greater impact on the circulating spray effect. Second, there is no designed lighting device. For the desulfurization tower set outdoors, when the light is poor at night, it is impossible to clearly observe the operation of the device, and it is impossible to make a correct judgment on the state of the device in time. When the equipment is abnormal, it is impossible to provide good lighting for maintenance personnel to repair the device. Summary of the Utility Model

An inlet 5 is provided on one outer wall of the flushing water tank 4, and the inlet 5 is used to add the required water source into the flushing water tank 4.

[0022] Working principle: When using the present utility model, first, the required water source is added to the flushing water tank 4 through the water inlet 5, and the opening of the slurry circulation pipeline 13 and the flushing water return pipe 11 is controlled by the flushing water pump 7 and the slurry circulation pump 14. Flue gas is discharged into the desulfurization tower 1 through the flue gas inlet 27. The slurry circulation pipeline 13 extracts slurry from the slurry storage tank 21 through the slurry circulation pump 14 and sputters it outwards through the slurry circulation spray 15 to treat the flue gas. The slurry in the desulfurization tower 1 absorbs sulfur dioxide in the flue gas during the contact process to form sulfuric acid solution. The function of the slurry circulation pump 14 is to extract the solution that has absorbed sulfur dioxide from the bottom slurry storage tank 21 of the desulfurization tower 1 and send it back into the slurry circulation spray 15 through the working pressure of the pump to achieve recycling. The slurry circulation pump 14 can also adjust the temperature of the desulfurization tower 1 by controlling the circulation speed of the absorption liquid. By adjusting the flow rate of the pump, the residence time of the absorption liquid in the desulfurization tower 1 can be changed, thereby affecting the rate and effect of the desulfurization reaction, effectively promoting the progress of the desulfurization reaction, improving the desulfurization efficiency. At the same time, by adjusting the temperature, the efficiency and stability of the entire desulfurization process are ensured. The filtered flue gas enters the demister main body 19 through the partition main body 17. During this process, the partition flushing spray 16 extracts the required water source from the flushing water tank 4 through the partition flushing branch pipe 8 on the flushing pipeline 6 to regularly flush the partition main body 17, remove the scale and residues on the partition main body 17, keep it clean, thereby improving the desulfurization efficiency and flue gas quality, keeping the demister clean and operating efficiently, and thus improving the performance and reliability of the entire desulfurization system. The flushing water after flushing does not enter the slurry and returns to the flushing water tank 4 through the flushing water return pipe 11, which is beneficial to stabilizing the concentration of the slurry and the balance of the water volume, and is beneficial to the circulation spraying effect or slurry concentration crystallization. Generally, it is beneficial to the treatment of waste gas. When the flue gas enters the demister main body 19, the lower flushing spray 18 and the upper flushing spray 20 extract water sources from the flushing water tank 4 through the lower flushing branch pipe 9 and the upper flushing branch pipe 10 to spray the demister main body 19, effectively separating the liquid droplets entrained in the gas in the tower to ensure the mass transfer efficiency, reduce the loss of valuable materials and improve the operation of the compressor behind the tower. The demister can effectively remove fog droplets of 3 - 5 μm, ensure the mass transfer efficiency of the tray, and reduce the plate spacing. The filtered flue gas is processed through subsequent sections and discharged through the smoke exhaust port 3; during the operation of the device, the operator can reach the lower operating platform 2 and the upper operating platform 22 through the ladder 12 to detect the device. At the same time, the solar photovoltaic panel 23 can perform photoelectric conversion during the day and store the electric energy in the energy storage box 24. When the light is insufficient at night, the energy storage box 24 can be controlled through the connection circuit 25 to provide power to turn on the lighting lamp 26 to provide lighting.
