[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for the production of medical thermal sensitive films. Background Technique

[0002] Medical thermal sensitive film is a commonly used medical imaging film. It uses heat-sensitive materials and prints images through near-infrared rays and laser printers. During the production process of medical thermal sensitive films, some harmful waste gases need to be purified before they can be discharged to avoid air pollution.

[0003] At present, during the process of purifying and treating the harmful waste gas generated by the production of medical thermal sensitive films through spray tower spraying, the spray heads used for spraying are usually fixed. The uniformity of the mixture of the harmful waste gas discharged into the spray tower and the water mist is poor, resulting in a reduction in the purification efficiency of the harmful waste gas and easily leading to unqualified waste gas treatment. For this reason, we propose a waste gas treatment device for the production of medical thermal sensitive films. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waste gas treatment device for the production of medical thermal sensitive films, which has the advantages that during the process of spray purification treatment of the waste gas generated by the production of medical thermal sensitive films, the spray heads can rotate and spray, so that the sprayed water mist and waste gas are fully mixed, improving the waste gas purification efficiency, and solving the problem that during the process of purifying and treating the harmful waste gas generated by the production of medical thermal sensitive films through spray tower spraying at present, the spray heads used for spraying are usually fixed, the uniformity of the mixture of the harmful waste gas discharged into the spray tower and the water mist is poor, resulting in a reduction in the purification efficiency of the harmful waste gas and easily leading to unqualified waste gas treatment.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A waste gas treatment device for the production of medical thermal sensitive films, including a filter cylinder, a fan and a spray tower. The end of the output pipe of the fan is fixedly connected to the outer surface of the spray tower near the lower surface position. The end of the input pipe of the fan is fixedly connected to the outer surface of the filter cylinder. An air inlet pipe is fixedly connected to the upper surface of the filter cylinder. A rotating shaft is rotatably installed inside the spray tower. A fan blade is fixedly installed on the outer surface of the rotating shaft near the lower surface position. One end of the rotating shaft above the fan blade is fixedly connected to a branch pipe. A plurality of nozzles are fixedly installed at equal intervals on the lower surface of the branch pipe. The upper surface of the branch pipe is rotatably connected to a medicine pipe through a rotary joint. An air outlet pipe is fixedly connected to the upper surface of the spray tower.

When the fan works, the harmful waste gas generated in the production of medical thermal-sensitive films enters the inside of the filter cylinder through the intake pipe, and the dust and impurities are filtered out. The filtered waste gas enters the inside of the spray tower and blows the fan blades to rotate, then the rotating shaft drives the branch pipe and the spray head to rotate. The spraying medicine is transported to the inside of the branch pipe through the medicine pipe and sprayed out by the spray head. The rotating spray head sprays the medicine water mist and the waste gas are fully mixed and react, so that the waste gas is purified and treated, and the purified waste gas is discharged from the outlet pipe.

The end of the output pipe of the fan 3 is fixedly connected to a position on the outer surface of the spray tower 4 close to the lower surface, and the end of the input pipe of the fan 3 is fixedly connected to the outer surface of the filter cartridge 1. An intake pipe 2 is fixedly connected to the upper surface of the filter cartridge 1. The harmful waste gas generated during the production of medical thermal sensitive film is sucked into the interior of the filter cartridge 1 from the intake pipe 2. A rotating shaft 16 is rotatably installed inside the spray tower 4. A fan blade 17 is fixedly installed at a position on the outer surface of the rotating shaft 16 close to the lower surface. A reduced diameter pipe 8 is fixedly installed at a position on the inner wall of the spray tower 4 close to the lower surface, and the reduced diameter pipe 8 is communicated with the output pipe of the fan 3. The waste gas in the fan 3 is blown towards the fan blade 17 by the reduced diameter pipe 8. The reduced diameter pipe 8 makes the waste gas more concentrated and increases the air pressure of the waste gas blown towards the fan blade 17, which is beneficial to driving the fan blade 17 to rotate.

[0023] One end of the rotating shaft 16 located above the fan blade 17 is fixedly connected to a branch pipe 14. A plurality of spray heads 15 are fixedly installed at equal intervals on the lower surface of the branch pipe 14.

A packing layer 10 is fixedly installed at a position inside the spray tower 4 above the branch pipe 14. The packing layer 10 enables the chemical agent and the waste gas to further contact and react, so that the waste gas purification treatment is complete. A demister 11 is fixedly installed at a position inside the spray tower 4 above the packing layer 10. The water mist contained in the purified waste gas is removed by the demister 11.

[0024] When the utility model is in use, the fan 3 works, and the harmful waste gas generated during the production of medical thermal-sensitive film enters the inside of the filter cylinder 1 through the air inlet pipe 2, and dust and impurities are filtered out. The filtered waste gas enters the inside of the spray tower 4 and drives the fan blade 17 to rotate, so that the rotating shaft 16 drives the branch pipe 14 and the nozzle 15 to rotate. The spraying agent is transported into the branch pipe 14 through the agent pipe 13 and sprayed out by the nozzle 15. The rotating nozzle 15 sprays the agent water mist and the waste gas are fully mixed and reacted, so that the waste gas is purified. The purified waste gas is discharged from the air outlet pipe 12.

A filter screen cylinder 6 is fixedly installed on the upper surface of the bottom plate 5, and the filter screen cylinder 6 is located inside the filter cylinder 1. The upper part of the filter screen cylinder 6 is open, and the waste gas inside the air inlet pipe 2 is directly connected into the filter screen cylinder 6. A sealing ring 7 is fixedly installed on the outer surface of the filter screen cylinder 6 near the upper surface, and the sealing ring 7 contacts the top of the inner wall of the filter cylinder 1 to play a sealing role.

[0027] In this embodiment, during the process of waste gas filtration, dust and impurities are collected inside the filter screen cylinder 6. When cleaning, remove the fixing bolts between the bottom plate 5 and the filter cylinder 1, and the filter screen cylinder 6 can be taken out from the inside of the filter cylinder 1, and the dust and impurities can be cleaned off.
