| titleOfInvention | A device for preparing ultra-high-purity acetone by membrane adsorption |
| abstract | The utility model relates to the technical field of acetone, in particular to a device for preparing ultra-high-purity acetone through membrane adsorption, which comprises a main body of a cracked gas cooler, and a circulation device and a refrigeration device are arranged on one side of the main body of the cracked gas cooler. The inside of the main body of the cracked gas cooler is provided with a cooling liquid, the circulation device and the refrigeration device are connected by a connecting pipe, the inner wall of the refrigeration device is provided with an installation groove, and a semiconductor refrigeration chip is installed in the installation groove. The heating end of the semiconductor refrigeration sheet is provided with several groups of radiating plates, and the cooling end of the semiconductor refrigeration sheet is provided with several groups of copper sheets. The circulation device and the refrigeration device are used to maintain the low temperature state of the cooling liquid, so as to avoid cooling the cooling pipe for a long time. Cause the temperature of the cooling liquid to be too high, so as to avoid the decrease of the cooling effect. |
