Description
Technical field
The utility model relates to a kind of device that efficiently prepares magnesium hydroxide.
Background technology
Magnesium hydroxide, as a kind of green material, is widely used in fire-retardant material, agricultural, environmental protection aspect.The mode of industrial acquisition magnesium hydroxide is generally 5 kinds: 1, with Wingdale and bittern reaction, produce magnesium hydroxide; 2, react hydrogen manufacturing magnesium oxide with sodium hydroxide and bittern, enriched bittern cake; 3, utilize burnt magnesite, rhombspar and bittern, enriched bittern cake reaction to produce magnesium hydroxide; 4, react hydrogen manufacturing magnesium oxide with ammoniacal liquor and bittern, enriched bittern cake; 5, utilize the magnesium oxide aquation to generate magnesium hydroxide, the magnesium oxide here must be that light-burned product is to guarantee the activity of aquation.The most frequently used is to adopt the mode of aquation light calcined magnesia to obtain magnesium hydroxide, and aquation is all to complete under the condition that stirs usually, and the condition of aquation is substantially: 30～60 ℃ of hydration temperatures; Magnesium oxide concentration of slurry 5～20%(w/w); Hydration time 1～24h, aquation rate 60～80%.
In sum, the magnesium oxide aquation prepares the problem that the magnesium hydroxide technical field exists: due to the long residence time, traditional magnesium oxide aquation prepares magnesium hydroxide and is that the volume of batch process, reaction vessel is large, hydration efficiency is not high, the aquation rate is lower.
Summary of the invention
The utility model, by control pressure and temperature, makes magnesium oxide and steam reaction, the purpose that reach stable, efficiently prepares magnesium hydroxide slurry.
the utility model provides a kind of device that efficiently prepares magnesium hydroxide, comprise mixing tank, pressure-controlling linkage unit I, reactor, pressure-controlling linkage unit II, condenser, two-position three-way valve, storage tank, pressure-controlling linkage unit III, vapour generator, described mixing tank discharge port is connected by pump with pressure-controlling linkage unit I one end, the pressure-controlling linkage unit I the other end is connected with the reactor feed mouth, the reactor discharge port is connected with pressure-controlling linkage unit II one end, the pressure-controlling linkage unit II the other end is connected with condenser one end, the condenser the other end is connected with the two-position three-way valve first interface, two-position three-way valve the second interface is connected with mixing tank returning charge mouth, two-position three-way valve the 3rd interface is connected with storage tank, the reactor vapor entrance is connected with pressure-controlling linkage unit III one end, the pressure-controlling linkage unit III the other end is connected with vapour generator.
Pressure-controlling linkage unit described in the utility model is preferably by pressure transmitter and magnetic valve and forms.
In prior art, Water Molecular Adsorption is to the magnesium oxide particle surface, the magnesium hydroxide that reaction forms covers on the magnesium oxide particle surface, hindered the carrying out of further hydration reaction, when device described in the utility model prepares magnesium hydroxide, high-pressure water vapor directly contacts with solid, and gas-solid reaction occurs, and the magnesium hydroxide that generates on the magnesium oxide particle surface is peeled off rapidly, magnesium oxide particle continues by aquation, obtains magnesium hydroxide slurry after cooling.
