| titleOfInvention | Recovery device for high purity or toxic fluid |
| abstract | The utility model discloses a recovery device of high-purity or toxic fluid, which comprises an inner layer pressure container, a middle layer pressure container, an outer layer vacuum container, a thermal switch of the inner layer pressure container, pipelines and valves of all containers, and the like; the inner layer pressure container is used for containing high-purity or toxic fluid media, an annular closed space formed by the middle layer pressure container and the inner layer pressure container can be filled with liquid nitrogen or other low-temperature fluids, the outer layer vacuum container can provide a vacuum environment to reduce heat leakage, and a thermal switch connected with a corrugated pipe is designed between the inner layer pressure container and the outer layer vacuum container and can be switched on and off on the premise of ensuring vacuum. When the middle-layer pressure container is filled with liquid nitrogen or other low-temperature fluid, the lower vapor pressure is obtained in the inner-layer pressure container, so that the recovery of high-purity or toxic fluid is realized. The utility model discloses convenient to use, easy to maintain, the reaction is rapid, and equipment has realized miniaturized integration, can be in the armed state for a long time. |
