Description

Technical Field

[0001] The invention relates to the technical field of post-ether carbon tetra-deacidification separation equipment, in particular to a post-ether carbon tetra-deacidification device. Background Art

[0002] Etherified C4 is the C4 remaining after isobutylene is removed by etherification reaction, mainly butene-1, butane, cis-trans butene-2, etc. Compared with the residual C4, it is less isobutylene. The industry requires that the remaining C4 after etherification should not contain acetic acid. If it contains acid, it will cause corrosion of the spherical tank storing the C4 after etherification, which will cause great economic losses to the owner. The existing deacidification device generally cannot mix the C4 mixture with the desiccant very fully, resulting in incomplete drying. It is difficult to recover the remaining desiccant after drying, which is relatively wasteful. At the same time, the gas after drying is still mixed with impurity gases such as butene.

[0003] China Patent Publication No. CN 219333720 U discloses a post-etherification carbon four deacidification device, including a dewatering tank, the inner wall of the dewatering tank is fixedly connected with a spiral copper tube, the top of the spiral copper tube is fixedly connected with an air inlet pipe, the air inlet pipe runs through the top of the dewatering tank and extends to the outside, the bottom of the spiral copper tube is fixedly connected with a gas outlet, the gas outlet, the top side of the dewatering tank is fixedly connected with a high-pressure blower, and the output end of the high-pressure blower is fixedly connected with an air inlet pipe. In this scheme, by setting up a spiral copper tube and a high-pressure blower, the carbon four gas mixture remaining after the etherification reaction can fully react with the desiccant in the spiral copper tube to remove moisture and acidic substances in the mixed gas. The high-pressure blower accelerates the reaction rate and can discharge the remaining desiccant in the spiral copper tube from the discharge pipe for recycling, while preventing the spiral copper tube from being blocked and affecting subsequent deacidification.

[0004] However, the above scheme still has the following problems: a large amount of harmful gas is generated during the deacidification of post-ether carbon tetrachloride, and if it is not treated in time, it is easy to cause equipment corrosion on the one hand, and pollute the working environment on the other hand. At the same time, there is a single treatment method for post-ether carbon tetrachloride, which leads to a long deacidification cycle, time-consuming and labor-intensive situation, and the overall flexibility of use is low, which cannot meet the needs of normal use. Therefore, the present invention needs to design a post-ether carbon tetrachloride deacidification device to solve the above problems. Summary of the invention
