Abstract
The invention relates to the field of dropwise-adding systems adopted in glue manufacturing, in particular to a dropwise-adding method adopted in glue manufacturing. Specifically, in the dropwise-adding process of a solution from a dropwise-adding tank to a glue reaction still, the multi-point dropwise-adding method or multi-part dropwise-adding method is adopted; the multi-point dropwise-adding method means that the solution is added onto multiple positions around the upper end of the glue reaction still dropwise at the same time through pipelines from the dropwise-adding tank; the multi-part dropwise-adding method means that the solution is added onto the upper end, the middle section and the lower end of the glue reaction still dropwise at the same time through pipelines from the dropwise-adding tank, the solution which has a high boiling point and is not prone to vaporization is added onto the upper end dropwise, and the solution which has a low boiling point and is prone to vaporization is added onto the middle section and the lower end dropwise. The method has the advantages that the design method is ingenious, operation is convenient, the reaction effect can be improved through the multi-point dropwise-adding method, reaction is made milder and more stable, and the reaction conversion rate is increased through the multi-part dropwise-adding method.
Description
Technical field
The present invention relates to glue manufacture and drip system regions, be specifically related to a kind of glue manufacture dropping method.
Background technology
In the past in glue manufacture process, during dropwise reaction, usually drip side, the upper end point that solution is directly added drop-wise to reactor, there are some problems like this, a bit dripping solution can not mix in time, and cause reaction uneven, reaction efficiency is low; Different for some solution boiling points, be all added drop-wise to reactor upper end, will gasify in the too high dropping upper end of temperature, cause some solution fully to react, waste raw material, reaction conversion ratio is low.
Summary of the invention
In order to solve foregoing invention problem, the present invention proposes a kind of glue manufacture dropping method, method for designing is ingenious, easy to operate, improves reaction effect, and reaction milder is steady, improves reaction conversion ratio.
A kind of glue manufacture dropping method, specifically being to drip when tank drips solution in glue reactor adopts multiple spot to drip or multiple location dropping method, and multiple spot dropping method drips tank, by pipeline, solution is added drop-wise to the multiple position of surrounding, glue reactor upper end simultaneously; Multiple location dropping method drips pipe, by pipeline, solution is added drop-wise to the upper end of glue reactor, interlude and lower end simultaneously, drips solution boiling point height and not easily vaporize and to drip with regard to upper end, drip the low easy gasification of solution boiling point and drip with regard to interlude and lower end.
It is that on glue reactor, end housing surrounding is designed with several dropping pipes that described multiple spot drips, and some dropping pipes are connected on the lower end outlet header of dropping tank by pipeline simultaneously, and described some dropping pipes are equipped with solenoid electric valve.
It is that glue reactor upper end, interlude and lower end are designed with dropping pipe respectively that described multiple location drips, upper end, interlude are connected on the lower end outlet header of dropping tank by pipeline with the dropping pipe of lower end position simultaneously, and described some dropping pipes are equipped with solenoid electric valve.
Described dropping tank lower end export pipeline is equipped with constant-delivery pump.
Advantage of the present invention is that method for designing is ingenious, easy to operate, and multiple spot drips can improve reaction effect, and reaction milder is steady, and multiple location drips and improves reaction conversion ratio.

Detailed description of the invention
With reference to accompanying drawing 1-2, a kind of glue manufacture dropping method, specifically being to drip when tank 1 drips solution in glue reactor 2 adopts multiple spot to drip or multiple location dropping method, and multiple spot dropping method drips tank, by pipeline, solution is added drop-wise to the multiple position of surrounding, glue reactor upper end simultaneously; Multiple location dropping method drips pipe, by pipeline, solution is added drop-wise to the upper end of glue reactor, interlude and lower end simultaneously, drips solution boiling point height and not easily vaporize and to drip with regard to upper end, drip the low easy gasification of solution boiling point and drip with regard to interlude and lower end.
Fig. 2 is glue reactor housing upper end top view, it is that on glue reactor 3, end housing surrounding is designed with several dropping pipes that described multiple spot drips, some dropping pipes are connected on the lower end outlet header of dropping tank 1 by pipeline simultaneously, and described some dropping pipes are equipped with solenoid electric valve 3.
Fig. 1, it is that glue reactor 3 upper end, interlude and lower end are designed with dropping pipe respectively that described multiple location drips, upper end, interlude are connected on the lower end outlet header of dropping tank 1 by pipeline with the dropping pipe of lower end position simultaneously, and described some dropping pipes are equipped with solenoid electric valve 3.
Described dropping tank 1 lower end export pipeline is equipped with constant-delivery pump 4.
The present invention also can drip and multiple location dropping combination by multiple spot, determine that dripping position is upper end, interlude or lower end according to boiling point, then determine that dripping position drips the need of multiple spot as required, need some to drip simultaneously, then control the switch of solenoid electric valve, be transported to the dropping point of specifying by constant-delivery pump or deadweight.
