Description

[0002] With the continuous development of industrial production, a large amount of waste gas is generated during the production process of chemical products such as dimethylaminocyclobutyl oxalate. These waste gases often contain harmful chemicals, posing a potential threat to the environment and human health. Therefore, how to efficiently and environmentally friendly treat these waste gases has become an urgent problem to be solved in the chemical production process.

[0003] The traditional method for treating waste gas produced by dimethylaminocyclobutyl oxalate often uses water washing and adsorption to treat the waste gas. However, during the adsorption process, when the activated carbon block is saturated with adsorption, it is necessary to stop the machine and replace the activated carbon block, which not only affects the continuity of waste gas treatment, but also increases the treatment cost. In addition, when harmful substances in the waste gas come into contact with water, if the contact area is insufficient, the water washing efficiency will be greatly reduced, and effective treatment of the waste gas cannot be achieved. Therefore, a waste gas treatment device for the production of dimethylaminocyclobutyl oxalate is proposed. Utility Model Content

At the same time, another unused activated carbon block 9 is rotated to the middle position of the outlet pipe 10 and the outlet pipe 2 11, so that the activated carbon block 9 can be replaced without stopping the machine, thereby ensuring the continuity of the exhaust gas treatment, improving the use efficiency of the activated carbon block 9, and reducing the treatment cost.

There are four groups of tripods 25 in total. There are several groups of rotating blades 18. The rotating blades 18 are evenly arranged on the driving shaft 17. The driving shaft 17 is arranged inside the waste gas treatment tank 1. The driving shaft 17 is arranged at the lower end of the circular partition 2.

The circular turntable 8 is arranged at the upper end of the circular partition 2. The circular partition 2 is connected with an outlet pipe 10. The outlet pipe 10 is arranged at the lower end of the outlet pipe 2 11. By starting the driving motor 2 15 to drive the rotation of the rotating blades 18, the water inside the treatment tank is constantly rolling and shaking, which greatly increases the contact area between the waste gas and the water, thereby further improving the water washing efficiency of the waste gas, and the waste gas produced by dimethylaminocyclobutyl oxalate is efficiently treated by water washing.

[0030] Working principle: First, the staff opens the valve 23 to inject water into the waste gas treatment tank 1 through the water pipe 22, and then blows the waste gas after the production of dimethylaminocyclobutyl oxalate from the air inlet pipe 21 into the waste gas treatment tank 1 through the air pump.

The pulley 1 16 and the pulley 2 20 respectively drive the drive shaft 17 to rotate, and the drive shaft 17 drives the rotating blade 18 to rotate.

Then, the washed waste gas flows to the water solution. The activated carbon block 9 is passed through the air outlet pipe 10 to further adsorb and treat the harmful gases in the exhaust gas. After the activated carbon block 9 between the air outlet pipe 10 and the air outlet pipe 2 11 is saturated with adsorption, the drive motor 4 is started to drive the worm 5 to rotate, the worm 5 drives the worm wheel 6 to rotate, the worm wheel 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the circular turntable 8 to rotate, and the circular turntable 8 drives the activated carbon block 9 between the air outlet pipe 10 and the air outlet pipe 2 11 to rotate away from the air outlet pipe 10 and the air outlet pipe 2 11, and the other unused activated carbon block 9 rotates to the middle position between the air outlet pipe 10 and the air outlet pipe 2 11. At this point, the saturated activated carbon block 9 is replaced without stopping the exhaust gas treatment, and finally the treated exhaust gas leaves the interior of the exhaust gas treatment tank 1 through the air outlet pipe 2 11.
