[0002] The main function of the tail gas absorption device for hydrochloric acid storage tanks is to treat and reduce the acidic gases and acid mists generated during the storage, transportation or use of hydrochloric acid. These acid mists are mainly formed by the volatilization of hydrochloric acid (HCl) and contain hydrogen chloride gas. If not controlled, they will cause various harms to the environment and human health. The acid mist absorption device can effectively capture and neutralize the hydrochloric acid mist discharged from the exhaust port of the hydrochloric acid storage tank, prevent it from diffusing into the atmosphere, reduce air pollution, and meet the environmental protection standards and requirements. Inhaling hydrochloric acid mist will cause irritation and harm to the human respiratory system, and can cause respiratory diseases in severe cases. By installing an acid mist absorber, the health and safety of on-site operators can be protected. Hydrochloric acid mist has strong corrosiveness and can quickly corrode the surrounding metal equipment and buildings, shortening their service life. Using an absorption device can avoid this corrosion damage, extend the equipment life, and reduce the maintenance cost.

[0003] However, during the use of the existing tail gas absorption device for hydrochloric acid storage tanks, the temperature of the equipment will rise, affecting the solubility of hydrochloric acid gas, thereby affecting the absorption efficiency.

[0024] As Figures 1 - 5 shown, this utility model provides a technical solution: a tail gas absorption device for a hydrochloric acid storage tank, including a base 1. One side of the top end of the bottom base 1 is fixedly connected with a processing box 2. Four groups of connecting blocks 15 are fixedly connected to the top end inside the processing box 2. One side of the four groups of connecting blocks 15 is fixedly connected with a mounting plate 13. A water storage tank 17 is provided on one side of the mounting plate 13. A plurality of leak holes 14 are provided on the other side of the mounting plate 13. One side of the water storage tank 17 is inserted and connected with a connecting pipe 16. One side of the top end of the processing box 2 is fixedly connected with a water pump 8. One end of the water pump 8 is connected with a guide rod 18. One end of the guide rod 18 is connected with a water tank 5. The bottom end of the water tank 5 is communicated with a sprinkler head 19. The other end of the water pump 8 is communicated with a water pipe 9. The sprinkler head 19 is arranged on the top end of the water storage tank 17. One end of the water pipe 9 is communicated inside the connecting pipe 16.

[0025] In this embodiment, the base 1 is provided to facilitate the installation and fixation of the processing box 2 and the storage tank 7. Then, under the action of the connecting block 15, the mounting plate 13 can be fixed to the inner top end of the processing box 2. Open the control valve provided on one side of the bottom end of the water tank 5, so that the cold water inside the water tank 5 is sprayed from the nozzle 19 into the water storage tank 17 and stored therein. Under the action of the leakage holes 14, the cold air emitted by the cold water flows into the inner bottom end of the processing box 2, thereby cooling the processing box 2 and preventing the temperature of the processing box 2 from being too high during long-term use, which may affect the absorption efficiency subsequently. The water pump 8 and the water storage tank 17 can be connected together using the water pipe 9 and the connecting pipe 16. The water pump 8 is convenient for sucking the used water inside the water storage tank 17 back into the water tank 5 again, so as to achieve the effect of recycling.

[0026] Embodiment 2

[0027] As Figures 1 - 5 shown, on the other side of the top end of the processing box 2, a cylinder 10 is fixedly connected. The output end of the cylinder 10 is connected to a power cord 4. One end of the power cord 4 is connected to a storage box 3. The bottom end of the storage box 3 communicates with a vacuum tube 21. The bottom end of the vacuum tube 21 is fixedly connected to a shower head 20. A round tube 6 is inserted through the middle of the processing box 2. One end of the round tube 6 is connected to a storage tank 7. The bottom end of the storage tank 7 is fixedly connected to the other side of the base 1. At the inner top end of the storage tank 7, a circular connecting pad 11 is fixedly connected. Inside the circular connecting pad 11, a filter plate 12 is fixedly connected.

[0028] In this embodiment, through the provided cylinder 10 and power cord 4, it is convenient to spray the hydrochloric acid stored inside the storage box 3 from the vacuum tube 21 and the shower head 20 to the bottom end of the processing box 2, without the need to open the storage box 3 to add hydrochloric acid, avoiding leakage during the addition process and causing construction accidents. When the hydrochloric acid reaction inside the processing box 2 is completed, open the valve on one side of the round tube 6, so that the reacted gas is inhaled into the storage tank 7. Under the action of the filter plate 12, the impurities contained on the surface of the gas can be filtered, improving the purity of the gas. The circular connecting pad 11 can be used to fix the filter plate 12, preventing the filter plate 12 from falling off during use and affecting the subsequent use effect.

[0029] Working principle of this embodiment: During use, first install the device in an open location. Then, use the cylinder 10 and the power cord 4 to spray the hydrochloric acid stored inside the storage tank 3 from the vacuum tube 21 and the shower head 20 onto the bottom end of the processing tank 2. There is no need to open the storage tank 3 to add hydrochloric acid, avoiding leakage during the addition process and preventing construction accidents. When the hydrochloric acid reaction in the processing tank 2 is completed, open the valve on one side of the round tube 6 to suck the reacted gas into the storage tank 7. Under the action of the filter plate 12, impurities on the surface of the gas can be filtered, improving the purity of the gas. The circular connecting pad 11 can be used to fix the filter plate 12 to prevent the filter plate 12 from falling off during use and affecting the subsequent use effect. During the operation process, simultaneously open the control valve on one side of the bottom end of the water tank 5, so that the cold water inside the water tank 5 is sprayed from the nozzle 19 into the water storage tank 17 and stored. Under the action of the leakage holes 14, the cold air emitted by the cold water flows into the bottom end of the processing tank 2, thereby cooling the processing tank 2 and preventing the temperature of the processing tank 2 from being too high during long-term use and affecting the subsequent absorption efficiency. The water pump 8 and the water storage tank 17 can be connected together using the water pipe 9 and the connecting pipe 16. The water pump 8 is convenient for sucking the used water inside the water storage tank 17 back into the water tank 5 again, thereby achieving the effect of recycling.
