Description

A kind of intermediate for producing high collapse-preventing type polyether monomer to pretreatment feeding-distribution device
Technical field
The manufacture of high collapse-preventing type polyether monomer production equipment is the utility model is related to, specifically a kind of high protect of production is collapsed The intermediate of type polyether monomer to pretreatment feeding-distribution device.
Background technology
Polyether monomer is mainly used in building trade, as the primary raw material of concrete additive, by development for many years The increasing market share is won with the characteristic of high water reducing rate, by years development from lipid to ethers, adaptability is also more next Better.
Because the gap of various regions sand material and binder materials is larger, slump loss in actual production is caused to be difficult to Keeping, polyether monomer currently on the market is mainly used to produce the water reducer of high water reducing rate, but for the sand materials such as Beijing ratio Poor construction market must just add special guarantor agent of collapsing and be adjusted.
The content of the invention
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided one kind produces high collapse-preventing type The intermediate of polyether monomer is to pretreatment feeding-distribution device, and technical scheme is used by the utility model solves its technical problem: Structure of the present utility model includes middle measuring tank A, middle measuring tank B, pretreatment kettle, valve, instrument, vacuum pipe, tail gas Pipeline, nitrogen pipeline, go main reaction kettle pipeline A, jet chimney A, cooling water return pipeline A, jet chimney B, circulation cold But water water return pipeline B, steam condensate (SC) pipeline A, recirculated cooling water water supply pipeline, steam condensate (SC) pipeline B, circulating cooling are waterborne Waterpipe, remove main reaction kettle pipeline B, remove main reaction kettle pipeline C, it is characterised in that middle measuring tank A, middle measuring tank B with it is pre- Handle kettle connection.
A kind of intermediate for producing high collapse-preventing type polyether monomer to pretreatment feeding-distribution device, it is characterised in that centre meter Vacuum pipe, exhaust pipe are set on measuring tank A and middle measuring tank B, nitrogen pipeline, remove main reaction kettle pipeline A, is pre-processed on kettle Jet chimney A, cooling water return pipeline A, jet chimney B, cooling water return pipeline B, steam condensate (SC) pipe are set Road A, recirculated cooling water water supply pipeline, steam condensate (SC) pipeline B, recirculated cooling water water supply pipeline, remove main reaction kettle pipeline B, go Main reaction kettle pipeline C, each pipeline are controlled and monitored with instrument by valve.
Pretreating process flow:First deionized water is squeezed into reactor by meter, then NaOH solid state powders are led to Cross screw feeder to be slowly added in reactor, and be stirred continuously, control temperature is made between 80 DEG C~90 DEG C by vavuum pump Vacuum state is in kettle, 99% methallyl alcohol of barreled is squeezed into head tank with pump, is added by meter in reactor, It is stirred continuously, methallyl alcohol, NaOH and input amount mol ratio are 30: 1, methallyl alcohol and NaOH reaction methallyl sodium alkoxide And water, in terms of methallyl alcohol, up to 98%, reaction generation water and raw material deionized water pass through reactivity as water vapor Vavuum pump is constantly deviate from, and reaction is carried out to the right, methallyl alcohol is fully reacted generation methallyl sodium alkoxide, reaction with NaOH After end, the solution is sent into polymerization reaction kettle by solution based on methallyl sodium alkoxide by pump in kettle.
The beneficial effects of the utility model are that the utility model more quick, more efficient can distribute material, significantly increase The production efficiency of polyether monomer is added.
