Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, and more specifically, to a flue gas desulfurization device. Background Art

[0002] Industrial flue gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes in the factory area of ​​an enterprise. If the flue gas is discharged directly into the atmosphere without treatment, it will pollute the air. These flue gases contain a variety of substances that are harmful to human health, some of which directly cause harm, and some have an accumulation effect, which will more seriously endanger human health. An existing flue gas desulfurization device usually uses appropriate alkaline substances to react with acidic substances in the flue gas to remove sulfur dioxide. In the existing use process, the equipment used is usually large, and the time for the alkaline substance to react with the flue gas is short, resulting in incomplete removal of sulfur dioxide in the industrial flue gas. It will still pollute the air when discharged into the air, and even endanger human health after a long time. Therefore, this paper is committed to a new type of flue gas desulfurization device.

[0029] A rectangular plate 8 is fixedly installed inside the desulfurization box 1. A circular hole 9 is opened on the top of the desulfurization box 1 and penetrates the rectangular plate 8;

[0030] Before use, fill the bottom of the desulfurization box 1 with enough calcium oxide solution and then connect the air inlet pipe 11 to the industrial flue gas pipeline. When in use, start the water pump 2. The power generated by the water pump 2 transports the calcium oxide solution at the bottom of the desulfurization box 1 to the inside of the water collecting plate 4 through the inside of the water delivery pipe 3, and flows through the short pipe 5 to the inside of the connecting pipe 6 and is atomized by the atomizing nozzle 7 and then sprayed out. At the same time, the industrial flue gas enters the circular hole 9 on the surface of the rectangular plate 8 and reacts with the atomized calcium oxide solution to generate solid calcium trisulfide particles that fall downwards. The purified gas is discharged from the inside of the desulfurization box 1 through the air outlet pipe 12.

[0031] Start the water pump 2. The force generated by the water pump 2 transports the calcium oxide solution to the inside of the water collecting plate 4 through the water supply pipe 3. The solution then flows into the inside of the connecting pipe 6 and is atomized. The solution is then sprayed out by the atomizing nozzle 7 to react with the industrial flue gas in the circular hole 9 to generate solid calcium trisulfide particles. The purified gas is discharged through the exhaust pipe 12. Compared with the traditional device, this device improves the reaction efficiency by allowing the industrial gas to enter the narrow circular hole 9 and directly react with the atomized calcium oxide above it, thereby achieving a better purification effect.

After pulling it to a certain distance, the particles inside the collection box 16 are cleaned;

[0037] The filter plate 13 is placed in an oblique state so that the particles falling on its surface slide through the rectangular groove 14 into the interior of the collection box 16. The staff pulls the collection box 16 to clean the particles inside. Compared with the traditional device, this device avoids disconnection when the collection box 16 is pulled through the card connection between the slide groove 17 and the protrusion 18, thereby ensuring the normal use of the collection box 16, and collecting the solid calcium sulfide particles on the surface of the filter plate 13 through the collection box 16 to avoid accumulation on the surface of the filter plate 13, thereby affecting the purification effect.

[0049] The desulfurization box 1 is made of stainless steel, which has good rust resistance, ensuring that the desulfurization box 1 will not rust after long-term use. A waterproof layer is coated on the inner wall of the desulfurization box 1 to avoid water seepage during long-term use. The connecting pipe 6 corresponds to the circular hole 9 one by one to ensure the atomization effect.

[0050] The working principle and use process of this utility model:

[0051] Before use, fill the bottom of the desulfurization box 1 with enough calcium oxide solution and then connect the air inlet pipe 11 to the industrial flue gas pipe. When in use, start the water pump 2. The power generated by the water pump 2 transports the calcium oxide solution at the bottom of the desulfurization box 1 to the inside of the water collecting plate 4 through the inside of the water supply pipe 3, and flows through the short pipe 5 to the inside of the connecting pipe 6 and is atomized by the atomizing nozzle 7 and then sprayed out. At the same time, the industrial flue gas enters the circular hole 9 on the surface of the rectangular plate 8 and reacts with the atomized calcium oxide solution to generate solid calcium trisulfide particles that fall downwards. The purified gas is discharged from the inside of the desulfurization box 1 through the air outlet pipe 12.

[0052] The solid particles of calcium trisulfide generated after the reaction fall downward to the surface of the filter plate 13. Since the filter plate 13 is tilted, the particles on the surface of the filter plate 13 fall into the interior of the collection box 16 through the rectangular groove 14. At this time, the staff pulls the collection box 16, and the chute 17 at the bottom is pulled out from the surface of the protrusion 18. After being pulled to a certain distance, the particles inside the collection box 16 are cleaned.
