Device for transient reaction of chemical product and use method thereof

Abstract

The invention discloses a device for transient reaction of a chemical product and a use method of the device, belonging to the technical field of chemical reaction devices. The device comprises a material containing grove, a material dripping groove, a first raw material leading-in pipe, a second raw material leading-in pipe, wherein the material dripping groove is articulated with the material containing groove and is matched with a support frame; the upper part of the support frame is articulated with the back part of the material dripping groove; the lower part of the support frame is supported on the terrace of a used place; one end of the first raw material leading-in pipe is corresponding to the upper part of the material dripping part and provided with a material injecting hole; the other end of the first raw material leading-in pipe is matched with a valve; one end of the second raw material leading-in pipe towards the material dripping groove is matched with a material nozzle; the material nozzle is corresponding to the upper part of the material dripping groove; and the top part of the material dripping grove constitutes a material overflowing cavity. According to the invention, the device can satisfy a demand that first raw material and second raw material complete the transient reaction mutually on the material dripping groove; the raw material can be saved; and the quality of products can be ensured; a whole structure is simple; in addition, the method provided by the invention does not have rigorous operation demands and can ensure the realization of the technical effect of the device for the transient reaction of the chemical product.

Description

technical field [0001] The invention belongs to the technical field of chemical reaction devices, and in particular relates to a device for instantaneous reaction of chemical products, and also relates to its use method. Background technique [0002] As known to those skilled in the art, many chemical products have a reasonable reaction process, that is, there is a reasonable reaction time period, and some chemical products even react more fully when the reaction time is longer. But there are also some chemical products obtained by liquid-liquid reaction operation such as not limited to the monoethanolamine product of enumeration, this monoethanolamine product is obtained by the mutual reaction of ammonia water and ethylene oxide, and ammonia water and oxirane are not as people The longer the imagined reaction time, the better, but instant contact with each other to obtain monoethanolamine. Therefore, if the traditional production mode is followed, such as reacting ammonia ...

AI Technical Summary

Problems solved by technology

Therefore, if the traditional production mode is followed, such as reacting ammonia water and ethylene oxide in a reactor, the following disadvantages will occur: one, because ethylene oxide will continue to react with the product monoethanolamine, thereby consuming ethylene oxide The by-product diethanolamine is produced simultaneously with alkane, and ethylene oxide and diethanolamine will still continue to react to generate triethanolamine

Conventional way is that the feeding amount of ammoniacal liquor is excessive, and ammoniacal liquor is steamed after reaction finishes again, yet still can generate diethanolamine and triethanolamine, reduce the amount of product monoethanolamine, promptly the yield of monoethanolamine is low; It is difficult to control the process, and causes inactive consumption of ammonia water and / or monoethanolamine, which is not conducive to reasonable saving of raw materials; the third is that the input equipment is complex and expensive
