Taurine coarse grain treatment system

Abstract

The invention discloses a taurine coarse grain treatment system which comprises a coarse grain bin, a spraying absorption tower and an air inducing pipe connecting the coarse grain bin and the spraying absorption tower; the coarse grain bin is a closed bin body, a plurality of drying tables are arranged in the coarse grain bin, an air inducing cover is correspondingly arranged above each drying table; the air inducing cover is connected with the part, extending into the coarse grain bin, of the air inducing pipe; the part, extending into the coarse grain bin, of the air inducing pipe is located over the coarse grain bin; an air inducing fan is installed on the air inducing pipeline, and an outlet of the air inducing pipeline is connected with an air inlet of the spraying absorption tower. Through the mode, the method disclosed by the invention has the advantages that the crystals can be purified on the basis of not influencing the characters of the taurine crystals, comprehensive cyclic utilization of sulfur dioxide is realized while the purity of taurine is improved, and air pollution caused by direct dissipation of sulfur dioxide in the taurine crystals into air is effectively prevented.

Description

Technical field[0001]The present invention relates to the field of talleuric acid production, and more particularly to a taurine crude crystal treatment system.Background technique[0002]Taurine is an essential amino acid in the human body, and it has an important role in the development of the fetus and baby nervous system. Tipolane can be widely used in pharmaceutical, food additives, fluorescent whitening agents, organic synthesis, etc., or as biochemical reagents, wetting agents, pH buffers, and the like. A sulfite is generally used in the taurine treatment, so that there is a quite amount of sulfur dioxide molecules in the tumulfonic acid crystals that have just been obtained from the solution, and these sulfur dioxide molecules are not pre-removed. The storage and transportation process will be slowly released into the air, contaminated the air, and the sulfur dioxide molecules also affect the yield of the corresponding product when taurine is used as a raw material.Inventive c...

AI Technical Summary

Problems solved by technology

Sulfite is generally used in the taurine preparation process, so there will be a considerable amount of sulfur dioxide molecules in the taurine crystals that have just been obtained from the solution. If these sulfur dioxide molecules are not removed in advance, the It will be slowly released into the air during storage and transportation, polluting the air, and when taurine is used as a raw material, sulfur dioxide molecules will also affect the yield of the corresponding product
