Summary of the invention
The problem that the present invention mainly solves is to provide a kind of mechanism of producing glycine, this device is with chemical reaction kettle, decolouring still, filter, crystallization kettle, whizzer, Vacuumdrier combination, the equipment using is all general-purpose equipment, the ethanol that the raw material of use is 95% for Monochloro Acetic Acid, ammoniacal liquor, water, gac, content.
The technical solution used in the present invention is:
A mechanism of producing glycine, comprising: chemical reaction kettle, decolouring still, filter, crystallization kettle, whizzer, Vacuumdrier, it is characterized in that: chemical reaction kettle is provided with water inlet, Monochloro Acetic Acid import, ammoniacal liquor import, ammonia outlet, between chemical reaction kettle and decolouring still, be provided with the first shurry pump and pipeline, decolouring still is provided with gac import, between decolouring still and filter, be provided with the second shurry pump and pipeline, filter is provided with impurity outlet, between filter and crystallization kettle, be provided with the 3rd shurry pump and pipeline, crystallization kettle is provided with 95% ethanol import, liquid exit, between crystallization kettle and whizzer, be provided with the first transfer roller, whizzer is provided with water out, between whizzer and Vacuumdrier, be provided with second conveyor, Vacuumdrier is provided with product outlet.
Further technical scheme of the present invention is:
First, second, third described shurry pump is stainless steel shurry pump, and pipeline is polyethylene pipe.
First, second described transfer roller is rotary conveyor.
The invention has the beneficial effects as follows: a kind of mechanism of producing glycine is provided, and the advantage of this device is: use general-purpose equipment, rational in infrastructure, with short production cycle, product purity is high, can be mass, and can produce high-quality glycine.
