A kind of Iodine crystallizing evaporator, comprise vaporization chamber, heating clamber and salt pin, it is characterized in that, described vaporization chamber, heating clamber and salt pin connect as one formula structure from top to bottom, the feeding mouth that Iodine soak is arranged from vaporization chamber top adds, then heating clamber is entered into, heating tube is provided with in heating clamber, heating tube top arranges steam inlet, bottom arranges condensation-water drain, steam enters in heating tube and heats Iodine soak, vaporization chamber is arranged EGR Iodine soak to be circulated from vaporization chamber to heating clamber conveying, Iodine soak reaches explosive evaporation after uniform temperature, Iodine is concentrated separates out, the ratio of concentrated alga iodine solution is great, sink to the salt pin of bottom, eluriate after being separated and enter next procedure.Evaporative crystallization equipment needed thereby vaporization chamber, heating clamber, EGR and salt pin are integrated into one by Iodine crystallizing evaporator of the present invention, compact conformation, appearance and size reduces half than the vaporising device of same effect, has greatly saved manufacturing cost, reduces place area occupied.And the present invention adopts the structure of vaporization chamber, heating clamber one, improve the utilization ratio of steam heat, the structure of vaporization chamber, heating clamber split makes material can loses heat in transmitting procedure back and forth, thus heating material to evaporating temperature to be needed more heat and heat time, overall structure of the present invention effectively can reduce power consumption, improve working (machining) efficiency.
Further, described EGR is arranged on the top of vaporization chamber, and EGR adopts propeller agitator, and the shaft of propeller agitator stretches to heating clamber by vaporization chamber.Iodine crystallizing evaporator of the present invention utilizes propeller agitator to realize the circulation of Iodine soak between vaporization chamber and heating clamber, often circulate, material heats up 2 DEG C, thus realizes the continuous heating of material, finally makes material reach the temperature of explosive evaporation.Iodine soak can become more and more sticky in the process of evaporation, propeller agitator power is powerful, operate steadily, simple to operate, the stirring propelling of stable precision can be carried out to full-bodied liquid, avoid Iodine soak to become full-bodied concentrate after evaporation and effectively cannot carry out delivery cycle, improve stability and the performance of whole Iodine crystallizing evaporator.
Further, described propeller agitator adopts mechanical seal, two fulcrum supporting structure, ensure the stability of syndeton, improve running stability, and keep good sealing, material is avoided to scatter and disappear contaminated environment, and can effectively indirect steam be recycled, improve energy utilization rate, reduce power consumption.
Further, described vaporization chamber top is also provided with gas-liquid separator, and the indirect steam that Iodine soak evaporates is got rid of by gas-liquid separator.In the process of explosive evaporation, material can form foam with steam, foam can reduce the output of Iodine after directly discharging, also to environment, if the steam of entrained foam is recycled in heating clamber, can cause equipment corrosion, have a strong impact on service life of equipment.
Further, described gas-liquid separator arranges return duct, to vaporization chamber, isolated Iodine soak is back to vaporization chamber, recovered material, reduces and runs material phenomenon, improve output.
Further, described gas-liquid separator arranges the steam inlet of return tube to heating clamber, isolated Steam Recovery is recycled, and improves efficiency of energy utilization, reduces production power consumption, energy-conserving and environment-protective.
Further, described Iodine crystallizing evaporator integral diameter 1600mm, height overall 4000mm, select 316L stainless steel to make, appearance and size is little, has greatly saved manufacturing cost, reduce place area occupied, stainless steel is made and effectively can be avoided bacteria breed, long service life.
Further, described heating tube adopts seamless steel pipe to make, and heating surface (area) (HS is 65M
2, heat exchanger effectiveness is high, shortens the heat time, enhances productivity.
Compared with prior art, the invention has the advantages that:
Evaporative crystallization equipment needed thereby vaporization chamber, heating clamber, EGR and salt pin are integrated into one by Iodine crystallizing evaporator of the present invention, compact conformation, appearance and size reduces half than the vaporising device of same effect, has greatly saved manufacturing cost, reduces place area occupied; Increase gas-liquid separator, be conducive to technological operation, recovered material, greatly reduce and run the generation of material phenomenon, improve output, improve efficiency of energy utilization, reduce production power consumption, energy-conserving and environment-protective.
