[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1) During operation, oxygen is introduced into the slurry through a gas hood made of nano-scale sintered mesh.

[0033] Working principle: when working, firstly, the slurry is passed into the reactor base 3 from the feeding pipe 5, and flows upward through the reactor body 1, when the top end liquid surface of the slurry rises to the same height of the discharging pipe 9, the slurry flows out from the discharging pipe 9;

[0034] In the slurry flow process, the vortex fan is opened, oxygen is driven from the first air inlet pipe 1002 into the air cavity 1008, and is blown out from the through-out head 1010 towards the slurry through the air passage 1012, the longitudinal pipe 1003 and the internal cavity 1009, at the same time, the gas cover 1011 is installed in the through-out head 1010, the gas cover 1011 adopts nanometer sintered mesh, when oxygen passes through the sintered mesh, because the sintered mesh is composed of micro-pore and sintered material, the gas will be continuously divided in the sintered mesh, after flowing out of the sintered mesh, the flowing gas will be decomposed into micro-bubbles into the slurry under the cutting of the sintered mesh, so as to realize the rapid dissolution of the gas in the slurry, at the same time, the ultrasonic head 6 on one side of the reactor base 3 is opened, through the oscillation of the ultrasonic wave, the effect of oxygen dissolution is further improved, and the utilization rate of oxygen is improved;

[0035] Because the longitudinal pipe 1003 is coaxially arranged in the internal cavity of the reactor body 1, and oxygen is discharged from the through-out head 1010 on the side rod 1004 of the longitudinal pipe 1003 towards the opposite side of the slurry flow direction, under the impact force, the contact effect of oxygen and slurry is improved, at the same time, the inclined fan blade 1005 is arranged on the side rod 1004, in the slurry flow process, the fan blade 1005 is pushed to drive the longitudinal pipe 1003 to rotate continuously, so that the side rod 1004 rotates with the longitudinal pipe 1003, so that the oxygen discharge position is continuously changed, the contact effect of oxygen and slurry is further improved, and the utilization rate of oxygen is improved;

[0036] When the oxygen is dissolved, the excess oxygen and hydrogen sulfide gas generated by the sulfide are dissipated into the space above the discharge pipe 9 inside the reactor cover 7. During the rotation of the longitudinal pipe 1003, when the piston rod 1110 rotates with the longitudinal pipe 1003 away from the second fixed shaft 1114, the first piston 1108 is pulled upward by the connecting rod 1116. When the piston rod 1110 rotates with the longitudinal pipe 1003 to the side close to the second fixed shaft 1114, the first piston 1108 moves downward. When the first piston 1108 moves downward, the oxygen and hydrogen sulfide gas inside the reactor cover 7 are sucked into the space above the baffle 1101 in the longitudinal pipe 1003. When the first piston 1108 moves upward, the oxygen and hydrogen sulfide gas are pressed into the space below the baffle 1101 and discharged from the gas cover 1011 to the slurry, so that the excess oxygen can be recycled, the pollutant hydrogen sulfide is decomposed and removed at the same time, and the compounds required for the leaching process can be produced, turning waste into treasure. As the slurry flow rate increases, the rotation speed of the longitudinal pipe 1003 increases, the frequency of the reciprocating movement of the first piston 1108 increases, the amount of oxygen introduced into the slurry per unit time increases, and the slurry throughput and the amount of oxygen per unit time are proportional, thereby improving the leaching effect of valuable metals in the slurry;

[0037] When the amount of gas in the space above the discharge pipe 9 inside the reactor cover 7 decreases, a negative pressure is generated, which moves the second piston 1212 toward the inside of the reactor cover 7, thereby pulling the extrusion block 1207 to move, thereby pushing the baffle 1205 to move upward, so that the vortex fan can provide a part of the oxygen to the upper part of the slurry, ensuring the stability of the first piston 1108 to supplement the amount of oxygen in the slurry. At the same time, when the amount of gas is sufficient, the inner cavity of the reactor cover 7 is isolated from the external environment to prevent the escape of hydrogen sulfide gas.
