Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, in particular to a desulfurization device capable of improving reaction efficiency. Background Art

[0002] Flue gas desulfurization technology is a key link in air pollution control and is of great significance for reducing sulfur dioxide emissions and improving air quality. At the same time, flue gas desulfurization technology is widely used in industrial fields with relatively serious air pollution, such as electricity, steel, cement, glass, and waste incineration. With the improvement of environmental protection awareness, the market demand for flue gas desulfurization technology continues to grow.

[0003] In existing technologies, baking soda is commonly used to achieve the purpose of flue gas desulfurization. The principle of baking soda desulfurization is to use its alkaline properties to react chemically with sulfur dioxide (SO2) in the flue gas, converting SO2 into products such as sulfate, thereby reducing sulfur dioxide emissions. Specifically, when baking soda is sprayed into the flue gas, it reacts with SO2, water vapor, etc. to generate products such as sodium sulfate (Na2SO4). In this process, baking soda acts as a reducing agent and undergoes an oxidation-reduction reaction with SO2, ultimately fixing SO2 in sulfate.

[0004] However, in the existing technology, baking soda cannot be pre-treated during the process of using baking soda for desulfurization, and thus impurities inside the baking soda cannot be removed, resulting in low purity and poor activity of the baking soda, which is not convenient for subsequent contact and reaction with substances in the flue gas, thereby reducing the desulfurization efficiency.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0027] In one embodiment, for the above-mentioned baking soda inlet pipe 7, the baking soda inlet pipe 7 includes an accelerating tube 701 installed at the bottom end of the ventilation pipe 2 6, and a high-pressure blower 702 is provided at the bottom end of the accelerating tube 701, and a connecting pipe 703 is provided on one side of the accelerating tube 701, and a blower 704 is provided on one side of the connecting pipe 703. A baking soda access pipe 705 is provided on one side of the blower 704 and passes through the baking soda grinding assembly 8; the accelerating tube 701 is composed of a first channel 7011 and a second channel 7012, and the cross-sectional width of the second channel 7012 is greater than the cross-sectional width of the first channel 7011, so that when the blower 704 introduces baking soda into the accelerating tube 701, the high-pressure blower 702 can be used to blow air into the accelerating tube 701, thereby driving the air inside the accelerating tube 701 to flow rapidly. At the same time, the direction of the opening of the accelerating tube 701 gradually widens and is arranged in a trumpet shape, so that baking soda powder is not easy to accumulate, which facilitates the balance of the flow rate of baking soda and improves the reaction efficiency of baking soda.

[0028] In one embodiment, for the above-mentioned baking soda grinding assembly 8, the baking soda grinding assembly 8 includes a grinding box 801 installed on one side of the ventilation pipe 2 6, two sets of sliding rods 802 are provided inside the grinding box 801, and the outer sides of the two sets of sliding rods 802 are provided with sliding blocks 803, and one side of the sliding block 803 is provided with a hydraulic rod 1 804, and the bottom end of the sliding block 803 is provided with a hydraulic rod 2 805, and the bottom end of the hydraulic rod 2 805 is provided with a grinding roller 806; two sets of connecting plates 807 are provided inside the grinding roller 806, and the bottom end of the connecting plate 807 is provided with a plurality of groups of compression springs 808, and the plurality of groups of compression springs 808 are provided. A baking soda grinding frame 809 is provided at the bottom end; two sets of servo motors 810 are provided at the bottom end of the interior of the grinding box 801, and the output shaft of the servo motor 810 is provided with a rotating shaft 811, and a rotating block 812 is provided on one side of the rotating shaft 811; a connecting shaft 813 is provided inside the grinding box 801, and an inclined plate 814 is provided on the outer side of the connecting shaft 813, and an abutment block 815 is provided on the top of the inclined plate 814, so that impurities in the baking soda can be removed during the grinding process, its purity is improved, and the baking soda has a smaller particle size and higher activity, which is convenient for it to fully contact and react with substances in the flue gas, thereby improving the desulfurization efficiency.

[0029] The working principle of the baking soda grinding assembly 8 is as follows: the hydraulic rod 2 805 is started by the external controller, which drives the grinding roller 806 at the bottom end of the hydraulic rod 2 805 to move toward the baking soda grinding frame 809, and drives the hydraulic rod 1 804 during the movement. Under the action of the hydraulic rod 1 804, the hydraulic rod 2 805 moves on the outside of the sliding rod 802, so that the grinding roller 806 moves inside the baking soda grinding frame 809, and then the grinding roller 806 can be used to grind the baking soda in the frame.

The inclination of the inclined plate 814 is adjusted under the action of the rotating block 812, and then the abutment block 815 at the top of the inclined plate 814 can be used to apply force to the bottom end of the baking soda grinding frame 809 to grind the baking soda inside, thereby improving the grinding efficiency.

[0030] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0031] In actual application, a U-shaped reactor 5 is installed in the flue in front of the desulfurization tower 1. The flue gas reaches the injection point of baking soda through the ventilation pipe 2 6. The baking soda is crushed by the baking soda grinding component 8 and enters the ventilation pipe 2 6 through the baking soda inlet pipe 7. The baking soda reacts chemically with the flue gas to generate sulfide, thereby preliminarily reducing the sulfide content in the flue gas. This is the first stage of the desulfurization process.

[0032] Subsequently, after the flue gas enters the U-shaped reactor 5, calcium hydroxide is introduced through the calcium hydroxide inlet pipe 3, and then the flue gas continues to react with the injected calcium hydroxide. The calcium hydroxide further reacts with the SO2 in the flue gas to generate solid sulfide precipitate. This is the second stage of the desulfurization process, which further reduces the SO2 content in the flue gas. The SO2 content of the flue gas after treatment has been greatly reduced. Then the flue gas enters the desulfurization tower 1 for further desulfurization treatment to ensure that it will not cause pollution to the environment.

[0033] In summary, with the aid of the above-mentioned technical solution of the present invention, the present invention has a simple structure and is easy to operate. By providing the baking soda inlet pipe 7 and the baking soda grinding assembly 8, after the baking soda is ground, the baking soda can be accelerated to the interior of the ventilation pipe 2 6 and combined with the U-shaped reactor 5, further increasing the baking soda reaction time and improving efficiency, thereby facilitating improved desulfurization effects in the later stage. By providing the baking soda inlet pipe 7, the present invention can use the high-pressure blower 702 to blow air into the accelerating tube 701 when the fan 704 introduces the baking soda into the accelerating tube 701, thereby driving the rapid flow of air inside the accelerating tube 701. At the same time, the direction of the opening of the accelerating tube 701 gradually widens, forming a trumpet-shaped arrangement, so that the baking soda powder is not easily accumulated, which facilitates the equalization of the flow rate of the baking soda and improves the baking soda reaction efficiency. The utility model provides a baking soda grinding component 8 so that impurities in the baking soda can be removed during the grinding process, thereby improving its purity and making the ground baking soda have a smaller particle size and higher activity, so that it can fully contact and react with substances in the flue gas, thereby improving the desulfurization efficiency.
