Abstract
The invention discloses a reaction system for fumaric acid oxidizing stage, comprising a mixing tank, a benzene-air mixing reactor, an air tank and a steam drum. The mixing tank, the benzene-air mixing reactor, the air tank and the steam drum are connected in sequence through a pipeline; a blade stirrer is disposed in the air tank, and a liquid level plate is disposed in the steam drum. Compared with the prior art, the system with the air tank and the steam drum uses liquid level of the steam drum to determine air pressure in the mixing reactor and control the quantity of air an oxidizing process, increasing reaction yield.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of for fumaric acid oxidation panel response system.
Background technology
Fumaric acid preparation in need in the presence of a catalyst Oxybenzene to prepare crude product.Owing to phenyl ring is aoxidized by needs, needing strictly to control the amount of mixing air the most in the reaction, traditional reaction unit is simultaneously provided with feeding mouth and air intake, can not control the amount of air in course of reaction very well, causes side-product too much to affect yield.
Summary of the invention
Goal of the invention: present invention aim at for the deficiencies in the prior art, it is provided that a kind of for fumaric acid oxidation panel response system.
Technical scheme: in order to reach foregoing invention purpose, the present invention specifically uses following methods to realize: a kind of for fumaric acid oxidation panel response system, including blending tank, benzene air mixing reactor, air tank and drum, described blending tank, benzene air mixing reactor, air tank and drum are sequentially connected by pipeline；It is provided with fan blade agitator in described air tank, in drum, is provided with liquid level plate.
Wherein, described air tank connects drum by pipeline.
Beneficial effect:The present invention is compared with conventional art, after adding air tank and drum, utilizes the liquid level of drum to the air pressure determining in mixing reactor, controls the amount of air in oxidizing process, improve the yield of reaction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
One as shown in Figure 1 is used for fumaric acid oxidation panel response system, and including blending tank 1, benzene air mixing reactor 2, air tank 3 and drum 4, described blending tank 1, benzene air mixing reactor 2, air tank 3 and drum 4 are sequentially connected by pipeline；Being provided with fan blade agitator 31 in described air tank 3, be provided with liquid level plate 41 in drum 4, described air tank 3 connects drum 4 by pipeline.
