Background technology
In the prior art, all to use the evaporative crystallization operation in the production technology of most of inorganic salts.It generally is the principle of utilizing the boiling point attenuating of water under condition of negative pressure in traditional production operation, use cold boiler, after the heating of inorganic salts concentrated solution, evaporate wherein moisture, obtain supersaturated solution, and then change in the crystallizer and lower the temperature, make the solute crystallisation by cooling in the supersaturated solution, carry out Separation of Solid and Liquid by the centrifugation mode again, obtain the inorganic salts crystal.This production technology needs experience evaporate-crystallization-separation three steps operation from solution to the crystallization, more loaded down with trivial details; And the speed of evaporation and crystallization is slow, and the time that often needs to go through dozens of hour just can finish.And aborning, run into the situations such as inorganic salts caking toward the contact meeting, need could pack sale behind the broken caking.
At present, in existing cold boiler use procedure, generally all adopting Steam Heating, is by heat exchanger internal solution to be carried out heating evaporation.Because various inorganic salts constituents are different, this evaporator heat exchanger contact-making surface tends to occur the situations such as fouling, so that has reduced heat exchange efficiency.
For this reason, providing a kind of evaporation crystallization equipment that can effectively reduce cost of investment and effectively reduce operation energy consumption is this area problem demanding prompt solution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, design a kind of atomization and vaporization crystallizer that integrates the functions such as atomizing, evaporation, crystallization and crystal scale removal.The waste heat that this device rationally utilizes the evaporation hot blast to produce in Chemical Manufacture can be realized that one goes on foot and the evaporation of inorganic salts concentrated solution can be obtained solid crystal particle, and effectively reduce operating cost.
The technical solution scheme that realizes the object of the invention is: a kind of atomization and vaporization crystallizer, comprise blower fan (1), warm-air pipe (2), air-introduced machine (3), exhaust outlet (4), bagroom (5), atomizer (6), vaporization chamber (7), material pipe (8), feed bin (9), valve (10), discharging opening (11); It is characterized in that: blower fan (1) is connected with warm-air pipe (2), and the top of material pipe (8) is connected for the atomizer (6) of connection and with warm-air pipe (2) and vaporization chamber (7); The top of vaporization chamber (7) and air-introduced machine (3) junction are provided with bagroom (5), and bagroom (5) connects air-introduced machine (3), is provided with exhaust outlet (4) at air-introduced machine (3); The bottom of vaporization chamber (7) is provided with feed bin (9), in the junction of feed bin (9) and discharging opening (11) valve (10) is installed.
Beneficial effect of the present invention is:
Apparatus of the present invention can at first be atomized into the inorganic salts concentrated solution and be evaporated after fine drop is vaporific ejection again, thereby large with the contact with air area, and evaporation rate is fast; The evaporation thermal source is hot blast, takes full advantage of the waste heat that produces in the Chemical Manufacture; Evaporation, crystallization are all finished in air, so the crystalline particle that obtains is tiny evenly, without scale formation, need not to carry out fragmentation, and equipment fault are few again; By straying quatity and the hot blast amount of blasting and the hot blast temperature of regulator solution, can be adapted to evaporation and crystallization production that different inorganic salts crystalline solid are separated out solution; This device can be finished evaporation, crystallization, the separation of solution a step, can directly obtain finished product and discharge and can pack from discharging opening, has saved production link, effectively reduces cost of investment and operation energy consumption, has greatly promoted the efficient of evaporation and crystallization.
