A purification and filtration device is provided on the outside of the purification tank 1.

[0022] The purification and filtration device includes a heater 4 fixedly connected to the bottom wall of the purification tank 1, a condenser 5 fixedly installed on the left side of the purification tank 1, a suction pump 6 fixedly connected to the top of the filter box 3, a first connecting pipe 7 fixedly connected to the right side of the suction pump 6, a second connecting pipe 8 fixedly connected to the left side of the suction pump 6, a collection box 9 fixedly connected to the top of the filter box 3, a nozzle 10 fixedly connected to the bottom of the collection box 9, a first filter frame 11 and a second filter frame 12 arranged inside the filter box 3, a coarse filter screen 13 fixedly connected to the inside of the first filter frame 11, a fine filter screen 14 fixedly connected to the inside of the second filter frame 12, and a flow guide box 15 fixedly connected to the bottom wall of the filter box 3. In use, the heater 4 and the condenser 5 work together to purify the compound by distillation. During distillation, the mixture is heated to the boiling point, and then the vapor is cooled back to liquid by condensation to separate the target compound. The separated liquid containing the target compound is introduced into the separation tank 2 for further processing.

[0023] Furthermore, the purified waste liquid will be drawn by the suction pump 6 and subjected to double filtration through the cooperation of the coarse filter 13 and the fine filter 14 of the first filter frame 11 and the second filter frame 12.

[0026] Meanwhile, an air intake fan 17 is fixedly connected to the top of the exhaust gas treatment box 16, and embedded frames 18 are fixedly connected to the left and right sides of the inner wall of the exhaust gas treatment box 16. An air filter element 19 is snapped into the inner side of the embedded frame 18, and an air intake pipe 20 is fixedly connected to the right side of the exhaust gas treatment box 16. The air intake pipe 20 is connected to the purification tank 1.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, the mixture is purified by distillation through the cooperation of heater 4 and condenser 5. During distillation, the mixture is heated to the boiling point and then the vapor is cooled back to liquid by condensation to separate the target compound. The separated liquid containing the target compound is introduced into separation tank 2 for further processing. The purified waste liquid is drawn by suction pump 6 and subjected to double filtration through the coarse filter 13 and fine filter 14 of the first filter frame 11 and the second filter frame 12. Impurities are retained on the coarse filter 13 and fine filter 14, while the water is discharged into the guide box 15 for further harmless treatment. During this process, the waste gas generated during purification is drawn out by suction fan 17 and then purified by air filtration of air filter element 19 to avoid polluting the working environment.
