Description
Technical Field
The utility model relates to a supercritical CO 2 An extraction device, in particular to supercritical CO 2 A separation heater of an extraction device.
Background
Supercritical CO 2 In the extraction circulation process of the extraction device, the carbon dioxide coming out of the extraction kettle enters the separation kettlePreviously, the process temperature needed to be reached by separate heater heating according to the process requirements. Because the carbon dioxide from the extraction kettle is dissolved with the extraction product, the solubility of the extraction product and the carbon dioxide is changed after the pressure is reduced and the temperature is changed, and part of the extraction product is adsorbed on the tube wall of the heat exchange tube of the separation heater, so that the heat exchange effect of the separation heater is reduced, the inside of the heat exchange tube of the separation heater needs to be cleaned on time, but the existing separation heater has design defects, so that the cleaning of the heat exchange tube of the separation heater is difficult.
Disclosure of Invention
The utility model provides a convenient supercritical CO cleaning to the above deficiency 2 A separation heater of an extraction device.
The utility model discloses a realize like this: supercritical CO 2 A separation heater of an extraction device comprises a barrel, wherein a baffle plate is arranged in the barrel, a vertical tube nest is arranged in the barrel, an upper tube plate and a lower tube plate are respectively arranged at the upper end and the lower end of the barrel, the upper end and the lower end of the tube nest are fixedly connected with the upper tube plate and the lower tube plate in a sealing mode respectively, a lower end socket with a second flange is fixedly connected to the lower end of the barrel, the lower end socket is connected in a flange mode, and the bottom wall of the lower end socket is connected with CO 2 An outlet; the upper end of the cylinder is fixedly connected with an upper end enclosure with a first flange, the upper end enclosure is fixedly connected in a flange mode, and the top wall of the upper end enclosure is connected with CO 2 The inlet, the upper right portion of barrel is connected with the hot water export, and the left lower part of barrel is connected with the hot water import, and the hookup has hot water to arrange the clean mouth on the lateral wall of barrel below the hot water import.
With the above structure, when cleaning the inside of the tube array (heat exchange tube) of the separation heater, the pressure in the tube array is reduced to normal pressure, and CO is discharged from the upper end of the separation heater 2 Cleaning liquid is injected into the inlet, enters the tube nest through the inner cavity of the upper seal head 2 and then passes through the lower opening of the tube nest and CO 2 The outlet is discharged, and simultaneously the dirt of the tube array is washed out under the action of the cleaning liquid. Because the array of pipes are vertical, the dirt in the pipes can be washed down from top to bottom,the cleaning is easier, thereby solving the problem that the cleaning of the heat exchange tube is more difficult.
