[0002] Currently, a large amount of high-temperature waste gas is generated during laboratory experiments. In order to remove this waste gas, the laboratory is equipped with ventilation devices to facilitate the exhaust of the waste gas generated in the experiment. However, due to the large laboratory space, the exhaust rate is slow, and the experimenters will inhale some waste gas to varying degrees, which will harm their health. Therefore, we propose a laboratory exhaust gas condensation and collection device. Summary of the Invention

By designing a test bench and collection components, the high-temperature exhaust gas generated during laboratory work can be condensed in a timely manner, reducing the harmful substances contained in the exhaust gas and preventing personnel from inhaling excessive amounts of harmful exhaust gas. The exhaust gas is then discharged again and finally discharged into the room by the ventilation system installed in the laboratory. This effectively ensures that the high-temperature exhaust gas generated during experiments can be purified in a timely manner, reducing the harm to the health of workers.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5This utility model provides a technical solution: a laboratory exhaust gas condensation and collection device, including a test bench 1, a collection assembly on the front side of the test bench 1, the collection assembly including a gas collection hood 2 at the top of the test bench 1, an air inlet pipe 3 at the top of the gas collection hood 2, and a suction fan 4 at the bottom of the gas collection hood 2, the bottom of the air inlet pipe 3 is connected to a mounting box 5, an exhaust pipe 6 is provided on the side of the mounting box 5 away from the air inlet pipe 3, the rear side of the mounting box 5 is fixedly connected to the test bench 1, a special-shaped tube 7 is provided inside the mounting box 5, one end of the special-shaped tube 7 is connected to the air inlet pipe 3, and the other end of the special-shaped tube 7 is connected to the exhaust pipe 6, an exhaust fan 8 is provided at the top of the exhaust pipe 6, a semiconductor cooler 18 is provided on the front side of the mounting box 5, and the bottom of the special-shaped tube 7 is also connected to... There is a connecting pipe 9, and the bottom of the mounting box 5 is also provided with a support plate 10. The rear side of the support plate 10 is fixedly connected to the test bench 1. The top of the support plate 10 is provided with a collection box 11. The surfaces of the air inlet pipe 3 and the exhaust pipe 6 are both fixedly fitted with fixing blocks 12. The rear side of the fixing blocks 12 is fixedly connected to the test bench 1. The two sides of the collection box 11 are provided with side plates 15. The top surface of the side plate 15 is provided with a through hole 16. The inside of the through hole 16 is provided with a limiting post 17. The bottom end of the limiting post 17 is fixedly connected to the top surface of the support plate 10, so that when the collection box 11 is placed on the support plate 10, it can be limited and the stability is stronger. The gas collection hood 2 is located directly above the test bench 1, so that after the suction fan 4 is running, the exhaust gas generated in the experiment can be better sucked into the inside of the gas collection hood 2. Currently, laboratories generate large amounts of high-temperature waste gas during experiments. To remove this waste gas, ventilation systems are installed. However, due to the large laboratory space, the exhaust rate is slow, and researchers inevitably inhale some of the waste gas, which can be harmful to their health. During operation, the suction fan 4, exhaust fan 8, and semiconductor cooler 18 are powered on. The suction fan 4 draws the high-temperature waste gas into the inside of the gas collection hood 2, and then through the air inlet pipe 3 into the shaped tube 7. The semiconductor cooler 18 then condenses the high-temperature waste gas inside the shaped tube 7, producing waste gas condensate. The liquid is introduced into the collection box 11 through the connecting pipe 9 and collected, thereby reducing the harmful components in the exhaust gas. Then, under the action of the exhaust fan 8, the condensed exhaust gas is discharged through the exhaust pipe 6, and finally discharged into the room by the ventilation device installed in the laboratory. By designing the test bench 1 and the collection components, the high-temperature exhaust gas generated in the laboratory can be condensed in time, reducing the harmful substances contained in the exhaust gas and preventing personnel from inhaling excessive amounts of harmful exhaust gas. After that, it is discharged again and finally discharged into the room by the ventilation device installed in the laboratory itself, effectively ensuring that the high-temperature exhaust gas generated in the experiment can be purified in time and reducing the harm to the health of the staff.

[0019] In this embodiment, preferably, please refer to... Figure 2 , Figure 4 As shown, it also includes a filter assembly, which includes a filter box 13 installed in the middle of the exhaust pipe 6. The filter box 13 is equipped with an activated carbon filter screen 14. There are three activated carbon filter screens 14 in total, which makes the filtration effect of exhaust gas better. By designing the filter assembly, the high-temperature exhaust gas generated in the experiment can be filtered again after being condensed, effectively purifying the odor in the exhaust gas. The structure is simple and practical.
