[0002] An adsorption tower is a device used to adsorb substances from a gas or liquid mixture. It is usually used to separate and purify specific components in a gas or liquid. Adsorption is a physical or chemical process in which an adsorbent captures the target substance from a gas or liquid and retains it on its surface. An adsorption tower usually consists of one or more tower bodies filled with adsorbents. When a gas or liquid mixture passes through the adsorption tower, the target substance will be adsorbed by the adsorbent, while the remaining components pass through.

[0003] Choline chloride synthesis tail gas refers to the waste gas or emission generated in the process of choline chloride synthesis. Choline chloride is an important biogenic amine compound, which is usually produced by chemical synthesis in industry. In the process of choline chloride synthesis, some waste gas may be generated, which may contain unreacted raw materials, by-products, volatile organic compounds, etc. Choline chloride synthesis tail gas will pollute the air, affect human health and the environment, which requires the choline chloride synthesis tail gas to be treated. During the use of existing adsorption towers, there is often a liquid tank at the bottom to collect and treat the liquid in the tower.

[0025] The working principle of this utility model:

[0026] When it is necessary to open the cover 2b, the two push rods 803 are pushed in opposite directions by manpower, and the two positioning blocks 801 are moved in opposite directions, so that the two positioning blocks 801 are removed from the inside of the plug-in block 4. At this time, the cover 2b can be moved upward and out of contact with the liquid tank 1d, so that the stirring blade 2c and the multiple filter screens 303 can be cleaned. When it is necessary to fix the cover 2b, after the cover 2b is plugged and connected to the liquid tank 1d, the movement of the two positioning blocks 801 will cause the two elastic springs 802 to deform, and when the two push rods 803 are released, the two positioning blocks 801 rebound to the inside of the plug-in block 4 and the two push rods 803 rebound to their original positions. By running the motor 2a, the operation of the motor 2a will cause the stirring blade 2c to rotate, so that the inside of the liquid tank 1d The adsorption tower 1 can be rotated to prevent precipitation of impurities. The condensed water generated when the water agent is concentrated can be used instead of purified water as adsorption water, which can greatly reduce the amount of pure water used and reduce the water cost. The adsorption water in the salt-forming process contains hydrochloric acid and trimethylamine. After the two react in the adsorption tower 1, a trimethylamine hydrochloride solution is obtained, which is consistent with the composition of the salt-forming liquid. After the adsorption water is saturated, the pH is fine-tuned and the adsorption tower 1 of the condensation process is injected. The trimethylamine hydrochloride solution is used to adsorb the ethylene oxide tail gas generated in the condensation process. The adsorption effect is better than the adsorption effect of pure water on ethylene oxide. The trimethylamine hydrochloride solution is used to adsorb the ethylene oxide tail gas. The two substances react in the adsorption tower 1 to generate a choline chloride solution. The generated choline chloride solution can be passed into the condensation tank for fine-tuning and then concentrated and distilled together with the condensation liquid.
