[0032] Please see Figure 1-5 This utility model provides a technical solution: a multifunctional emergency chlorine gas treatment device, including a placement plate 1 and a gas collection hood 7;

[0033] The gas collection hood 7 is equipped with a circulation device;

[0034] The circulation device includes a treatment box 6, a pressure relief valve 4, and a blower 5. The upper surface of the gas collection hood 7 is arc-shaped. The treatment box 6 is fixedly connected to the upper surface of the gas collection hood 7. The pressure relief valve 4 is fixedly installed on the upper surface of the treatment box 6. The blower 5 is fixedly connected to the outer wall of one side of the treatment box 6. The interior of the pressure relief valve 4 is connected to the interior of the treatment box 6. The output end of the blower 5 is fixedly connected to the outer wall of one side of the gas collection hood 7 through a connecting pipe. A pipe mixer 3 is installed on the outer wall of one side of the treatment box 6. The input end of the blower 5 is fixedly connected to the upper surface of the treatment box 6 through a connecting pipe. The output end of the pipe mixer 3 is fixedly connected to the lower outer wall of the treatment box 6 through a connecting pipe. A spray nozzle 14 is installed on the upper inner wall of the treatment box 6. The input end of the pipe mixer 3 is fixedly connected to the spray nozzle 14 inside the treatment box 6 through a connecting pipe. A camera 11 is installed on the lower outer wall of the gas collection hood 7.

[0035] The upper surface of the placement plate 1 is equipped with multiple chlorine storage tanks 2. A remote-controlled trolley 16 is installed inside the gas collecting hood 7. Limiting grooves 12 are formed on both outer walls of the remote-controlled trolley 16. The outer walls of two connecting plates inside the gas collecting hood 7 are slidably connected to the interior of their respective limiting grooves 12. Second limiting block grooves 17 are formed on both inner walls of the two limiting grooves 12. First limiting block grooves 15 are formed on both outer walls of the two connecting plates inside the gas collecting hood 7. Limiting blocks 13 are slidably connected to the interior of each of the four first limiting block grooves 15. The ends of the four limiting blocks 13 closest to the second limiting block grooves 17 extend slidably into the interior of the limiting grooves 12 and contact the inner walls of their respective second limiting block grooves 17. Both sides of the protrusion 7 have push block grooves 9 on their outer walls. The interior of the two push block grooves 9 is connected to the interior of the connecting plate inside the corresponding gas collection hood 7. Two push blocks 8 are slidably connected inside the two push block grooves 9. The ends of the four push blocks 8 near the limiting block 13 are slidably extended into the interior of 48 and are fixedly connected to the outer wall of one side of the corresponding limiting block 13. Rubber clips 10 are slidably connected inside the two push block grooves 9. The outer walls of the two rubber clips 10 are in contact with the outer wall of one side of the corresponding push block 8. Three return springs 18 are provided inside the two push block grooves 9. The six return springs 18 are in groups of three. The two ends of the two groups of return springs 18 are fixedly connected to the outer wall of one side of the corresponding push block 8.

[0036] Furthermore, when using this device, it is started by connecting to an external power source. First, the placement plate 1 is placed in a sealed space. Then, the remote-controlled trolley 16 is remotely controlled via an external radio remote control to enter the sealed space. The condition of the sealed space is then observed through a camera 11 connected to an external device. When the chlorine storage tank 2 leaks, the leaking chlorine gas is visible through the camera 11 because it is heavier than air and has a color. After the remote-controlled trolley 16 is moved to a suitable position, the force generated by the fan 5 on the gas collection hood 7 causes the leaking chlorine gas to enter the interior below the gas collection hood 7. Then, the leaking chlorine gas is transported to the interior of the treatment tank 6 through the fan 5 and the connecting pipe. At the same time, sodium hydroxide is located at the bottom of the treatment tank 6, thus achieving the treatment of the gas inside the tank. A portion of the sodium hydroxide is neutralized with the leaked chlorine gas. Simultaneously, sodium hydroxide is extracted from the bottom of the treatment tank 6 through the pipe mixer 3. Then, the sodium hydroxide is mixed with the leaked chlorine gas through the pipe mixer 3. The mixture is then sprayed out through the connecting pipe and the spray nozzle 14, making the mixture more uniform. When it is necessary to remove the gas collection hood 7 from the remote control trolley 16, the rubber clip 10 is removed from the inside of the push block groove 9. Pushing the push block 8 moves in the opposite direction, causing the reset spring 18 to contract and simultaneously causing the limit block 13 to move in the opposite direction. Then, the opposite movement of the limit block 13 causes its other end outer wall to disengage from the inside of the second limit block groove 17. Finally, pulling the second limit block groove 17 removes the second limit block groove 17 and the treatment tank 6 from the remote control trolley 16.

[0037] The leaked chlorine gas is transported to the treatment tank 6 via a circulating device using a blower 5 and a connecting pipe. Sodium hydroxide is located at the bottom of the treatment tank 6, allowing some of the leaked chlorine gas to be neutralized by the sodium hydroxide. Simultaneously, a pipe mixer 3 extracts the sodium hydroxide from the bottom of the treatment tank 6 and mixes it with the leaked chlorine gas. This mixture is then sprayed out through a connecting pipe and a spray nozzle 14, resulting in more uniform mixing and significantly improving the efficiency of the chlorine-sodium hydroxide solution mixing, thereby enhancing the treatment efficiency. This improves efficiency and reduces operating costs. By removing the rubber block 10 from the inside of the push block groove 9, the push block 8 is pushed to move in the opposite direction, causing the reset spring 18 to contract and simultaneously causing the limit block 13 to move in the opposite direction. Then, by moving the limit block 13 in the opposite direction, its other end outer wall is disengaged from the inside of the second limit block groove 17. Then, by pulling the second limit block groove 17, the second limit block groove 17 and the processing box 6 can be removed from the remote control trolley 16. This facilitates the disassembly of the gas collection hood 7, effectively improving the maintenance and repair efficiency of the gas collection hood 7, while also improving the practicality and flexibility of the equipment, thereby improving the work efficiency of the staff.

[0038] Working principle: First, the placement plate 1 is placed in a sealed space. Then, a remote-controlled vehicle 16 is remotely controlled via an external radio remote to enter the sealed space. The condition of the sealed space is then observed through a camera 11 connected to an external device. When chlorine storage tank 2 leaks, the leaking chlorine gas is visible through the camera 11 because it is heavier than air and has a color. The remote-controlled vehicle 16 is then moved to a suitable position, and the force exerted by the fan 5 on the gas collection hood 7 causes the leaking chlorine gas to enter the area below the hood 7. The fan 5 and connecting pipe then transport the leaking chlorine gas to the inside of the treatment tank 6. Simultaneously, sodium hydroxide is present at the bottom of the treatment tank 6, ensuring that a portion of the treatment tank contains sodium hydroxide. The leaked chlorine gas is neutralized, and sodium hydroxide is extracted from the bottom of the treatment tank 6 through the pipeline mixer 3. The sodium hydroxide is then mixed with the leaked chlorine gas through the pipeline mixer 3, and then sprayed out through the connecting pipe and spray nozzle 14 to make the mixture more uniform. When it is necessary to remove the gas collection hood 7 from the remote control trolley 16, the rubber block 10 is removed from the inside of the push block groove 9. The push block 8 is pushed to move in the opposite direction, which causes the reset spring 18 to contract and the limit block 13 to move in the opposite direction. Then, the other end of the limit block 13 is disengaged from the inside of the second limit block groove 17 by the opposite movement of the limit block 13. Then, the second limit block groove 17 and the treatment tank 6 can be removed from the remote control trolley 16 by pulling the second limit block groove 17.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
