Distillation tower for production of methyl methacrylate

Abstract

The invention discloses a distillation tower for production of methyl methacrylate. The distillation tower includes a first control valve, a preheater, a second control valve, a tower body, condensers, a water tower and a third control valve. One end of the preheater is connected to the first control valve through a pipeline, and the other end is connected to a second control valve, the second control valve is in connection with the pipeline above the tower body, the tower body is connected to the condensers through the pipeline, and the condensers are in self-circulation connection with the water tower through a pipeline. The distillation tower for production of methyl methacrylate provided by the invention solves the defects of unstable product quality, many transition parts, repeated distillation and the like in the prior art, continuous distillation and batch distillation operations can be finished in one tower at the same time, and optimized combination of distillation technologies is realized under the circumstance of significant reduction of equipment investment, thus being conducive to enhance the comprehensive productivity. The distillation tower for production of methyl methacrylate has excellent practicability and generalizability and is equipped with double condensers, condensed water is stored through the water tower and is recycled by controlling the pressure through the third control valve.

Description

technical field [0001] The invention relates to teaching equipment for teachers, in particular to a distillation tower for producing methyl methacrylate, which belongs to the field of teaching appliances. Background technique [0002] In the production process of methyl methacrylate, domestic manufacturers will choose different rectification towers for production according to their own production processes. At present, there are two common operation methods: continuous rectification and batch rectification. Among them, continuous distillation is generally used for simple separation of components, while batch distillation is suitable for multi-component products. In actual production, the above two operation methods have their own strengths for different fields. However, it is difficult to meet the process requirements for multi-component materials that need to be recycled for some components, whether it is continuous rectification or batch rectification. On the other hand, ...

Problems solved by technology

In actual production, the above two operation methods have their own strengths for different fields. However, it is difficult to meet the process requirements for multi-component materials that need to be recycled for some components, whether it is continuous rectification or batch rectification. On the other hand, during the distillation process, the vaporized liquid rises quickly in the distillation tower, and there is no effective barrier on the way, so that the rising speed is too fast, and the expected distillation effect cannot be achieved, which is detrimental to the quality of the product. The cooling water in the condenser cannot self-circulate, so that the effect of rapid condensation cannot be achieved after vaporization
