Description

Technical Field

[0001] The utility model relates to the technical field of sulfolane production, in particular to a rectification device used in the production of sulfolane. Background Art

[0002] Sulfolane is an excellent non-protonic polar solvent, which is miscible with water, acetone, toluene, etc. It is also an ideal solvent in the process of aromatic extraction in petrochemical industry. Sulfolane is easy to decompose at high temperature. In the process of producing sulfolane, the crude sulfolane is sent to the distillation tower for distillation to obtain the sulfolane product.

[0003] According to the distillation device for producing sulfolane disclosed on the patent website (authorization announcement number: CN 209033797 U) described in "The distillation device for producing sulfolane relates to a distillation device used in the production of sulfolane. It is mainly designed to solve the problem that the purity of the sulfolane product distilled by the current distillation tower is not ideal. It includes a distillation tower, a feed inlet is provided at the bottom of the distillation tower, a product outlet is provided on the distillation tower above the feed inlet, a discharge outlet of sulfolane containing some impurities is provided on the distillation tower above the product outlet, an outlet is provided at the top of the distillation tower, a filler is provided in the distillation tower, a condenser is provided at the top of the distillation tower, an opening at the bottom of the condenser is connected to the outlet at the top of the distillation tower, and an impurity discharge outlet is provided at the top of the condenser; it also includes a cylinder, a gasified material outlet at the top of the cylinder is connected to the feed inlet at the bottom of the distillation tower through a first pipeline, a material inlet and a slag discharge outlet are provided at the lower part of the cylinder, a stirrer is provided at the bottom of the cylinder, and a heat exchange tube is provided in the cylinder; the discharge outlet of sulfolane containing some impurities is connected to the storage tank through a second pipeline. The advantage is that the sulfolane product after distillation has high purity."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During the use of the utility model, since the crude sulfolane first enters the cylinder, is heated by heat transfer oil in the cylinder, and then enters the distillation tower for distillation, the purity of the product can be improved to 99.9%. The sediment in the cylinder is stirred by the agitator, which is conducive to the discharge of the sediment. However, in actual use, as the agitator stirs the sediment, some sediments still cannot be discharged from the slag discharge port, resulting in some sediments staying on the bottom inner wall of the cylinder, and as the stirring work proceeds, the cylinder will shake, so the stability of the first pipeline cannot be guaranteed.
