Abstract
The utility model relates to an alginic acid propylene glycol ester reation kettle, its characteristic includes sealed reaction kettle, adds the heat channel, cools off recovery unit, high -order liquid storage pot. Wherein the sealed reaction kettle bottom is used for throwing in the algin acid for ethylene oxide's apotheca, centre are equipped with mesh partition, and reation kettle places in with the heat channel bottom. This device can the by heating be vaporized epoxypropane, and steam cycles through the algin acid and carries out esterification reaction, and epoxypropane finally retrieves recycling through condensation recovery device. The utility model discloses reation kettle has practiced thrift on the one hand the epoxypropane quantity greatly and has reduced manufacturing cost, and on the other hand makes that esterification reaction is more abundant, the reaction is rapider, has shortened production cycle.
Description
Technical field
This utility model relates to a kind of propylene glycol alginate reactor.
Background technology
Propylene glycol alginate (Propylene Glycol Alginate) english abbreviation PGA, is a kind of esterification derivative obtained by alginic acid and propylene oxide reaction.PGA has many advantages compared with alginic acid and alginate, PGA can formation thick gel soluble in water, and can be dissolved in organic acid soln and not saltouing, high to the stability of acid medium, additionally can stop because calcium and other high volence metal ion exist the precipitation caused, so PGA quickly grows at food and the beverage industries of low pH ranges, it is widely used.But traditional and existing PGA produces equipment to be fallen behind, there is the drawback that expoxy propane consumption is big, response time length, production cost are high, and this constrains the sound development of PGA industry significantly.
Summary of the invention
In order to solve the deficiency of existing equipment, this utility model provides a kind of propylene glycol alginate reactor, expoxy propane can be vaporized by this device by heating, and steam cycles through alginic acid and carries out esterification, and expoxy propane is eventually through condensate recycling device Recovery and recycle.
To achieve these goals, this utility model scheme is achieved in that it includes closed reactor, heating tank, cools back receiving apparatus, high-order fluid reservoir.Being placed in bottom closed reactor in heating tank, closed reactor is connected with cooling back receiving apparatus by pipeline, cools back receiving apparatus and connects with high-order fluid reservoir, and high-order fluid reservoir is connected with closed reactor by pipeline.
Improvement further to such scheme: be provided with in the middle of described closed reactor net-like spacer for throwing in alginic acid, bottom is the storage room of oxirane.
A kind of propylene glycol alginate reactor described in the utility model, can be vaporized expoxy propane by heating, and steam cycles through alginic acid and carries out esterification, and expoxy propane is eventually through condensate recycling device Recovery and recycle.
On the one hand a kind of propylene glycol alginate reactor described in the utility model is greatly saved expoxy propane consumption and reduces production cost, on the other hand promote esterification more fully, reaction rapider, shorten the production cycle.
Compared with prior art, advantage of the present utility model and good effect are mainly reflected in following 2 points:
(1) expoxy propane vapor esterification, for gas-solid reaction, expoxy propane can be fully contacted with alginic acid and react has saved the response time, the viscosity of the product of simultaneously the biggest reservation.
(2) using vapor esterification, the usage amount of expoxy propane is about 1 times of alginic acid raw material, only 1/3rd of traditional handicraft, greatly reduces the consumption of expoxy propane, reduces production cost.
