Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate production technology, and in particular to a purification device for tail gas from ammonium perchlorate production. Background Technology

[0002] Ammonium perchlorate is an important chemical raw material widely used in rocket propellants, pyrotechnics, and other fields. However, the production process of ammonium perchlorate inevitably produces exhaust gases containing chlorine, hydrogen chloride, and ammonia. Chlorine has strong oxidizing and irritating properties, which can severely damage the human respiratory tract and eyes, corrode equipment, and pollute the environment. Hydrogen chloride gas is highly soluble in water to form hydrochloric acid, which, when released into the atmosphere, forms acid mist that corrodes buildings, harms vegetation, and contributes to acid rain, disrupting the ecological balance. Ammonia has a strong pungent odor that pollutes the atmosphere, and the alkaline solution formed by ammonia dissolving in water affects the pH of soil and water bodies, thereby harming biodiversity.

[0003] Currently, common methods for treating tail gas from ammonium perchlorate production include chemical absorption and adsorption. In chemical absorption, some processes use only a single absorbent, directly treating the tail gas with sodium hydroxide solution. While this method has some absorption effect on acidic gases, the complex composition of the tail gas and the reaction of sodium hydroxide solution with various gases consume large amounts of reagents, significantly increasing treatment costs and making it difficult to meet the tail gas purification needs of large-scale industrial production. Therefore, this invention proposes a novel solution. Utility Model Content

A plurality of first nozzles 16 are fixedly connected to the surface of the second spray pipe 15.

[0034] The exhaust gas treatment assembly also includes a first treatment box 4, which is fixedly connected to the upper end of the base 1. A first fan 17 is installed on the upper end of the first treatment tank 3. The inlet and outlet ends of the first fan 17 are both fixedly connected to second connecting pipes 18. The two second connecting pipes 18 extend into the interior of the first treatment tank 3 and the first treatment box 4, respectively. A third nozzle 19 is fixedly connected inside the first treatment box 4. The third nozzle 19 is fixedly connected to the corresponding second connecting pipe 18. The third nozzle 19 is curled. A plurality of second nozzles 24 are also fixedly connected to the surface of the third nozzle 19.

[0035] A cyclone dust collector 2 is installed on the upper end of the base 1, and the exhaust end of the cyclone dust collector 2 is fixedly connected to the first connecting pipe 6.

[0036] The lower end of the first processing tank 3 is fixedly connected to the first drive motor 9, and the output end of the first drive motor 9 is fixedly connected to the rotating shaft 10. The rotating shaft 10 is rotatably connected to the first processing tank 3. Multiple spiral stirring blades 11 are fixedly connected to the surface of the rotating shaft 10. The multiple spiral stirring blades 11 are divided into two groups and symmetrically arranged on the surface of the rotating shaft 10.

[0037] A second processing box 5 is fixedly connected to the upper end of the base 1. An exhaust pipe 23 is fixedly connected to the upper end of the second processing box 5. A second fan 20 is fixedly connected to the upper end of the first processing box 4. A third connecting pipe 21 is fixedly connected to both the air inlet and outlet of the second fan 20. The two third connecting pipes 21 extend into the interior of the first processing box 4 and the second processing box 5, respectively. A fourth nozzle 22 is fixedly connected to the interior of the second processing box 5. The fourth nozzle 22 is curled. Multiple second nozzles 24 are also fixedly connected to the surface of the fourth nozzle 22.

[0038] Multiple connecting blocks 8 are fixedly connected to the inner wall of the first processing tank 3.

[0039] When using this device, the ammonium perchlorate production tail gas first enters the cyclone dust collector 2. The cyclone dust collector 2 uses the principle of centrifugal force to throw the solid particles in the tail gas against the wall of the device during high-speed rotation, thereby separating them from the tail gas and achieving preliminary purification. After being treated by the cyclone dust collector 2, the tail gas carries a significantly reduced content of solid impurities, which reduces the burden on subsequent processing components and also avoids interference from solid impurities in subsequent processing, such as clogging pipes or affecting chemical reactions. The purified tail gas enters the first treatment tank 3 through the exhaust end of the cyclone dust collector 2 and the first connecting pipe 6.

[0040] After the exhaust gas enters the first treatment tank 3, the first water pump 12 is activated. The first water pump 12 pumps the sodium carbonate solution drawn through the first water pipe 13 and delivers it to the second spray pipe 15 through the second water pipe 14. The solution is then sprayed into the first treatment tank 3 by multiple first nozzles 16 on the second spray pipe 15. Simultaneously, the second nozzles 24 on the surface of the first spray pipe 7 at the bottom of the first treatment tank 3 also spray out the exhaust gas delivered by the first connecting pipe 6. Inside the first treatment tank 3, acidic gases such as chlorine and hydrogen chloride in the exhaust gas react chemically with the sodium carbonate solution. The reaction of hydrogen chloride and sodium carbonate produces sodium chloride, water, and carbon dioxide; the reaction of chlorine and sodium carbonate... The solution reaction produces substances such as sodium chloride, sodium hypochlorite, and carbon dioxide. During the reaction, the first drive motor 9 is activated, which drives the rotating shaft 10 to rotate, thereby causing the spiral stirring blades 11 fixed on the surface of the rotating shaft 10 to rotate. The stirring action of the spiral stirring blades 11 increases the contact area between the sodium carbonate solution and the exhaust gas, accelerates the chemical reaction, and allows the acidic gas to be absorbed more fully. The connecting block 8 on the inner wall of the first treatment tank 3 can play a certain role in turbulence, further promoting gas-liquid mixing and improving absorption efficiency. After treatment by the first treatment tank 3, most of the acidic gas in the exhaust gas is removed.

[0041] The exhaust gas, after initial purification in the first treatment tank 3, is transported to the first treatment box 4 via the second connecting pipe 18 under the action of the first fan 17. The first treatment box 4 contains sodium carbonate solution, and the third nozzle 19 fixedly connected inside is coiled, which greatly increases the contact area between the solution and the exhaust gas. Multiple second nozzles 24 on the surface of the third nozzle 19 spray out the sodium carbonate solution, which comes into full contact with the exhaust gas entering the first treatment box 4. The small amount of acidic gases such as chlorine and hydrogen chloride remaining in the exhaust gas continue to react with the sodium carbonate solution and are further absorbed and removed, achieving deep purification of the exhaust gas.

[0042] After being purified by the first treatment chamber 4, the exhaust gas enters the second treatment chamber 5 through the third connecting pipe 21 under the action of the second fan 20. Sodium hydroxide solution is added inside the second treatment chamber 5, and the fourth nozzle 22 fixedly connected inside is also curled, with multiple second nozzles 24 on the surface spraying out the sodium hydroxide solution. At this time, the trace amounts of acidic gases and alkaline gases such as ammonia that may remain in the exhaust gas react with the sodium hydroxide solution. The acidic gases react with sodium hydroxide to produce corresponding salts and water, and the ammonia dissolves in the water in the sodium hydroxide solution. After being purified again by the second treatment chamber 5, the harmful gases in the exhaust gas are further removed, meeting the emission standards, and finally discharged into the atmosphere through the exhaust pipe 23.

[0043] Furthermore, the use of the first treatment tank 3 and the first treatment box 4 facilitates the preliminary and deep absorption and purification of the exhaust gas, enhancing the purification effect. The first treatment tank 3 removes most of the acidic gases in the exhaust gas, reducing the burden on subsequent purification steps. The first treatment box 4 allows the residual acidic gases in the exhaust gas to continue to react with the sodium carbonate solution, achieving deep purification of the exhaust gas, reducing the pressure on subsequent treatment, improving the overall purification effect, increasing treatment efficiency, and reducing treatment costs.

[0048] The first drive motor 9 at the lower end drives the rotating shaft 10 and the spiral stirring blades 11 to rotate, increasing the contact area between the sodium carbonate solution and the exhaust gas, accelerating the chemical reaction.
