A high-efficiency and energy-saving device for removing iodine from crude salt

Abstract

The present application relates to the technical fields of iodine removal of crude salt, and discloses a high-efficiency and energy-saving iodine removal device for crude salt, which comprises a salt dissolving pool assembly, a reagent tank assembly, a reaction tank assembly, a combustion tank assembly and an adsorption tower assembly, mainly solves the problems of low iodine removal efficiency and high energy consumption in the prior art, by injecting fresh brine into the salt dissolving pool, driving the ultrapure water metering pump to dilute, opening the stirring motor to disturb and pre-oxidize the brine, driving the hydrochloric acid metering pump to adjust the pH of the brine, driving the water inlet pump to inject the brine into the reaction tank, adding hydrogen peroxide by the hydrogen peroxide metering pump, opening the ultrasonic vibrator and the aeration ring, and through the synergistic effect of cavitation and micro-bubble aeration, the oxidation reaction is strengthened, the oxygen generated by the reaction is transported to the combustion chamber to mix and burn with hydrogen, the heat energy generated by the combustion is converted into electricity by the thermoelectric generator to supply power to the ultrasonic vibrator, the ultrapure water in the cold liquid cavity absorbs the waste heat to warm up and preheat the salt dissolving, and after the oxidation reaction is completed, the brine is collected into the adsorption tower assembly for adsorption, so that the content of iodine in the crude salt is efficiently removed.
