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

Embodiment 1

[0015] please see figure 1 , provides a storage tank 1 whose geometric shape is not limited by the shape shown in the figure, and a hinge seat 11 is respectively fixed on the walls of the storage tank 1 facing each other and located on the upper edge. The corresponding two sides of the bottom of a drip trough 2 are respectively hinged with the hinge seat 11 by the hinge shaft 22, and a bracket 21 is also provided on the drip trough 2, and the top of the bracket 21 is connected with the top of the drip trough 2. The back side is connected, and the bottom is fixed with an expanded fixed plate 211, and the fixed plate 211 can be fixed on the floor of the use place, and can also be fixed on the frame placed on the use place. Of course, the aforementioned drip tank 2 can also be referred to as a reaction bed. An overflow cavity 23 is formed on the top of the gutter 2 .

Abstract

Belonging to the technical field of chemical reaction equipment, the invention provides a device for a chemical product instantaneous reaction. The device includes: a material holding groove; a material flowing groove hinged to the material holding groove and also provided with a bracket, the upper part of which is hinged to the back of the material flowing groove and the bottom of which is equipped with a fixation plate through expanding; a first raw material inlet tube, one end of which corresponds to the upper part of the material flowing groove and is equipped with material injection holes, and the other end of which is provided with a valve; a second raw material inlet tube, which has one end facing the material flowing groove equipped with a material injecting nozzle. The material injecting nozzle corresponds to the upper part of the material flowing groove, and has a length matching the width of the material flowing groove. Specifically, the top of the material flowing groove forms a flash chamber, and the length of the end equipped with material injection holes on the first raw material inlet tube is consistent with that of the material injecting nozzle. The device provided in the invention has the advantages that: it can satisfy the requirements of a first raw material and a second raw material for finishing an instantaneous reaction on the material flowing groove mutually; raw materials can be saved and product quality can be guaranteed; and the overall structure is simple.

Description

technical field [0001] The invention belongs to the technical field of chemical reaction devices, in particular to a device for instantaneous reaction of chemical products. 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 water and ethylene oxide in a reactor, the follo...
