Description

Technical Field

[0001] The utility model relates to the technical field of trichloroethylene processing, in particular to a trichloroethylene gas condensation device. Background Art

[0002] Trichloroethylene is an organic compound with the chemical formula C2HCl3. It is a colorless liquid, poorly soluble in water, and has an odor similar to chloroform. Trichloroethylene has a wide range of applications in the industrial and scientific research fields. For example, it is used as a solvent for metal cleaning, dry cleaning, extraction of plant and mineral oils, etc. Due to its volatility and toxicity, it poses potential hazards to the environment and human health. Therefore, strict measures need to be taken during its use and management. It is widely used in the metal processing and surface treatment industries to clean metal workpieces. As an important chemical raw material, it is used to prepare plastics, synthetic fibers, pesticides, etc. During the preparation of trichloroethylene, the gas needs to be condensed and then collected.

[0003] In the utility model with the patent publication number CN208302431U, a condensation tube is arranged in the condensation box, and the filter box is communicated with the condensation tube. Here, the condensation tube is coiled from top to bottom, and the end of the condensation tube far away from the filter box extends out of the condensation box and is connected with a finished product box. In this way, the gaseous trichloroethylene entering the condensation box is cooled by the coolant outside the condensation tube and then enters the finished product box under its own gravity, which is convenient for the staff to collect and concentrate. Although this method can complete the condensation work, there are also problems. Since only the coiled condensation tube contacts the coolant, the contact surface between the two is single, and the contact area of the gas to be condensed in the condensation tube is reduced, which reduces the condensation efficiency and the subsequent continuous condensation treatment effect, and is not conducive to actual use.

[0004] Therefore, it is necessary to provide a trichloroethylene gas condensation device to solve the above technical problems. Summary of the Utility Model
