PREPARATION METHOD AND DEVICE FOR EFFICIENTLY PREPARING MAGNESIUM HYDROXIDE

摘要

The present invention relates to a device for efficiently preparing magnesium hydroxide, comprising a material mixing tank, a pressure control linkage unit I, a reactor, a pressure control linkage unit II, a condenser, a three-way valve, a material storage tank, a pressure control linkage unit III and a vapor generator. A discharging hole of the material mixing tank is connected with one end of the pressure control linkage unit I by a pump; the other end of the pressure control linkage unit I is connected with a feeding hole of the reactor; the discharging hole of the reactor is connected with one end of the pressure control linkage unit II ; the other end of the pressure control linkage unit II is connected with one end of the condenser; the other end of the condenser is connected with a first port of the three-way valve; a second port of the three-way valve is connected with a material returning hole of the material mixing tank; a third port of the three-way valve is connected with the material storage tank; a vapor inlet of the reactor is connected with one end of the pressure control linkage unit III; and the other end of the pressure control linkage unit III is connected with the vapor generator. The beneficial effect of the present invention is that magnesium hydroxide slurry can be prepared quickly and efficiently
