Description
Technical field
The present invention relates to chemical industry fixed-end forces field, more particularly, to the process for purification of the salt containing organic matter.
Background technology
The existing method to the salt containing organic matter, removed by rotary furnace or rake stove come Pintsch process, burning in salt
Organic matter, but cause the salt containing organic matter to bond blocking and be bonded on appts wall in temperature-rise period, and use
Existing rotary kiln or rake stove, which can not crush, bonds blocking salt, causes salt uneven heating, cracking not exclusively, in device to block up
Fill in, the salting liquid after dissolution filter is coloured, has taste, does not reach the purpose of organics removal.
It is an object of the invention to provide a kind of process for purification of the salt containing organic matter, existing process is overcome to containing organic
The salt of thing carries out salt in Pintsch process, burning process and easily bonds blocking or be bonded on appts wall the defects of can not crushing, together
When overcome the defects of crushing the equipment non-refractory for bonding blocking salt.The method that the present invention is heated up using segmentation stirring,
Preheating section ceaselessly stirs the blocking salt of broken bonding, the organic matter in salt is volatilized, heat cure, after obtaining loose preheating
Salt, it is preheated after salt again through rotary furnace or during rake stove Pintsch process, salt is prevented from caking and be heated evenly, organic cracking it is complete
Entirely, by dissolving, filtering, evaporative crystallization obtains colourless, odorlessness, the salt without organic matter.
What the object of the invention was realized in：A kind of process for purification of the salt containing organic matter, it is characterised in that to containing
The salt of organic matter first carries out the stirring preheating of ball milling formula, then by rotary furnace Pintsch process or rake stove Pintsch process, makes in salt
Organic cracking, charing, the salt after Pintsch process dissolves with water, filter after obtain transparent salt solution, described transparent salt solution
Again the salt of removal machine thing is obtained through evaporative crystallization.
On the basis of above-mentioned technical proposal, the present invention also has measure further below：
Described ball milling formula stirring preheating is being heated to be heated using tubular or ball shape rotary device
During toward solid particle is added in salt, rotated by rotating device, taking added solid particle to certain altitude falls, to salt
Bang is carried out to crush or grind.
Described solid particle is metallic particles, ceramic particle or stone particle.
Described ball milling formula stirring preheating temperature is 150~350 DEG C.
Described rotary furnace Pintsch process or rake stove Pintsch process temperature are 350~1500 DEG C.
Transparent salt solution is obtained after described filtering to filter by charcoal absorption before evaporative crystallization.
Transparent salt solution is obtained after described filtering and passes through ozonation aerated processing before evaporative crystallization.
Mixtures of materials after described the pre-heat treatment is separated salt with the solid particle added, solid by screening
Grain, which is rejoined in preheating device, to be recycled.
The invention advantage of the present invention is as follows：
Segmentation stirring heating is first carried out to the salt containing organic matter, it is pre- first to carry out the stirring of ball milling formula to salt at a lower temperature
Heat, organic matter in salt is set to volatilize and heat cure, because ball milling formula stirring power crushes block in time, the salt after preheating leads to again
Do not bonded during the high temperature stirring at low speed cracking for crossing rotary furnace or rake stove, salt is heated evenly, organic cracking is thorough, and process is molten
Solution, filtering, evaporative crystallization obtain colourless, odorlessness, the salt without organic matter.The present invention has that technique is simple, reliable, operation side
Just the advantages of, cost is low, environmental pollution is small.
