[0022] An ultrasonic wave oxidation iron removal device, comprising: a stock tank 01, a reaction kettle 10, an oxygen source 09.

[0023] In one embodiment, as shown in Figure 1 The stock tank 01 and the oxygen source 09 are connected with the reaction kettle 10;

[0024] The reaction kettle 10 is divided into a mixing conditioning area 04, a vortex reaction area 06 and a conical hole reaction area 07 from top to bottom, and the reaction kettle 10 is provided with an ultrasonic wave air vibration device 05.

[0027] In one embodiment, as shown in Figure 1 The stock tank 01 and the reaction kettle 10 are connected through a circulating pump 02, the input end of the circulating pump 02 is connected with the output end of the stock tank 01, the output end of the circulating pump 02 is connected with the top input end of the reaction kettle 10 and communicates with the mixing conditioning area 04.

[0028] In one embodiment, as shown in Figure 1 One side of the stock tank 01 is provided with a liquid outlet pump 08, the input end of the liquid outlet pump 08 is connected with the liquid outlet end of the stock tank 01, and the output end of the liquid outlet pump 08 is connected with subsequent equipment.

[0029] Working principle: the utility model discloses a working time, first, the stock solution is through pipeline and enters the stock solution tank 01, simultaneously high energy oxygen contactor 03 works, and oxygen source 09 carries out to the reaction kettle 10 and applies oxygen, when the oxygen of certain pressure and flow enters the reaction kettle, ultrasonic wave gas vibration device 05 is started, and 20kHz ultrasonic wave is generated, and under the action of ultrasonic wave, oxygen is activated and forms ten thousand active oxygen microbubbles, and active oxygen microbubbles and the solution (ore pulp) that is injected into the reaction kettle reaction area (reacts in turn through mixing conditioning area 04, vortex reaction area 06 and conical hole reaction area 07) from top to bottom rapidly fuse, and under the impetus of ultrasonic active oxygen gas, the solution (ore pulp) forms fog and oxygen atom group and constantly collides, rapidly reacts;

[0030] The transmission of the sound wave propagates longitudinally according to a sinusoidal curve, that is, one layer is strong and the next layer is weak, and when the weak signal acts on the liquid, a certain negative pressure is generated on the liquid, so that a large number of tiny bubbles are formed in the liquid; when the strong sound wave signal acts on the liquid, a certain positive pressure is generated on the liquid, so that the tiny bubbles formed in the liquid are crushed and a large number of micro-nano-sized small bubbles, cavitation bubbles, are generated. These bubbles grow in the negative pressure area formed by the longitudinal propagation of the ultrasonic wave, rapidly close in the positive pressure area, and are compressed and stretched under the alternating positive and negative pressures, and the oxygen and the metal ions in the solution repeatedly react, and then enter the high-speed rotating negative pressure convection area. Under the high-speed rotating negative pressure, the solution generates micro-nano-sized bubbles, increases the contact area, and the reaction rapidly proceeds.

[0031] After entering the stock solution tank 01, the micro-nano-sized bubbles again react with the solution through the high-energy oxygen contactor 03, and the iron ions are removed through cyclic collision. The solution is pumped into the reaction kettle 10 by the circulating pump 02, and oxygen is turned on at the same time. The reaction liquid that is fully mixed with oxygen enters the stock solution tank 01 under the action of the circulating pump 10. The ore pulp is continuously circulated in the stock solution tank 01 and the reaction kettle 10 until the reaction is completed, and then the waste liquid is output by the liquid outlet pump 08. The iron ions are removed through cyclic collision of the mixed reaction and the high-energy oxygen contactor 03, so as to improve the product quality and effectively recover the iron slag. The technical problems of extraction process and wet smelting iron removal have been solved for a long time.
