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
The present invention relates to a kind of teachers ' teaching and use equipment, be specially a kind of methyl methacrylate production destilling tower, belong to teaching aid field.
Background technology
In methyl methacrylate production process, domestic manufacturer all can select different rectifying columns to carry out the mode of production according to the production skill of controlling oneself, and comparatively general mode of operation divides two kinds at present: continuous rectification and batch fractionating.Wherein, continuous rectification is generally used for simple separation component, and batch fractionating is then applicable to multicomponent mixture product.In the middle of actual production, above-mentioned two kinds of modes of operation have his own strong points for different fields, but, the multi-component masses carrying out recycling is needed for constituent part, no matter be continuous rectification or batch fractionating, all be difficult to reach process requirements, on the other hand, the rising that the liquid be vaporized in still-process is very fast in destilling tower, not effective stop in way, make its rate of climb too fast, do not reach the distilling effect of anticipation, adverse influence is produced to the quality of product, cooling water in condenser can not self-loopa, the effect of rapid condensation is not reached after making vaporization.
Summary of the invention
Object of the present invention is just to provide a kind of methyl methacrylate production destilling tower to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of methyl methacrylate production destilling tower, comprise the first control valve, preheater, the second control valve, tower body, condenser, water tower and the 3rd control valve, it is characterized in that: described preheater connects the first control valve by pipeline one end, the other end connects the second control valve, and the second control valve connects tower body upper pipe, described tower body connects condenser by pipeline, described condenser is connected with water tower self-loopa by pipeline, and self-loopa pipeline is provided with the 3rd control valve.
Preferably, described tower body is also provided with sine and cosine plate, pressure control handle and discharging opening, and described sine and cosine plate is arranged in tower body, and described pressure control handle is positioned at the left side at tower body top, and described discharging opening is positioned at the bottom of tower body.
Preferably, described sine and cosine plate is provided with some equally distributed through holes, and the lateral length of sine and cosine plate is 1/3 of tower body diameter.
Preferably, described condenser is provided with two.
Preferably, described condenser is connected by pipeline with condenser, and two condensers connect same water tower.
Compared with prior art, the invention has the beneficial effects as follows: this methyl methacrylate production destilling tower solves the unstable product quality existed in current technique, transition portion is more, want the defects such as distill repeatedly, the operation of continuous still and batch distillation can be completed in a tower simultaneously, the optimum organization of distillation technique is achieved when significantly reducing equipment investment, be conducive to improving comprehensive production capacity, save holistic cost, possess preferably practicality and replicability, and this methyl methacrylate production destilling tower is provided with double-condenser, condensed water is stored by water tower, control pressure by the 3rd control valve to recycle, good cooling results, in vaporescence, effectively stop vaporization rate too fast by sine and cosine plate, make distilling effect better.
