(3) Beneficial effects

Compared with the prior art, the present invention provides a regeneration tower for the gas-liquid phase catalytic oxidation process for removing hydrogen sulfide, which has the following beneficial effects:

1. When the present invention is in use, the air inlet pipe is connected to the external air source device, the rich liquid containing hydrogen sulfide is poured into the cylinder, and the output end of the pumping equipment is connected with the liquid inlet pipe for pumping rich liquid. When the gas enters the sleeve from the air inlet pipe through the aeration head, the air bubbles discharged through the aeration head form air bubbles when they float in the sleeve. When the air bubbles rise to the liquid surface, foam containing sulfur particles will appear. At this time, the transmission mechanism is started to work. When the transmission mechanism is working, the rising bubble layer is eliminated, thereby avoiding the fouling and clogging of the bubbles. When the bubbles are broken, the sulfur particles are concentrated on the inner wall of the cylinder under the action of the transmission mechanism and fall down, which can then be trapped in the cylinder. The sulphur particles are gradually precipitated at the bottom of the cylinder body and fall between the gap between the body and the sleeve, so that the cylinder body can be easily drawn out from the drain pipe for filtration.

2. The transmission mechanism provided in the present invention, when in use, starts the motor to drive the rotating shaft to rotate, and the rotating shaft rotates to drive the transmission rod to make the scraper make a circular motion. Quickly discharge the sleeve, drive the first pulley to rotate the second pulley when the shaft rotates, the second pulley rotates to drive the transmission shaft to rotate the gear, the gear rotates to drive the ring gear to rotate the casing, and the casing rotates to drive the support rod Make the swash plate make a circular motion. Since the steering of the first pulley and the second pulley is the same, and the gear is opposite to the ring gear, since the second pulley and the gear have the same steering, it can be seen that the rotation of the shaft and the casing is opposite, so The air bubbles scraped off by the scraper are impacted by the counter-rotating inclined plate to change the direction of movement, so that the sulfur particles in the air bubbles can have the initial velocity of falling into the rich liquid, which is conducive to the precipitation of the sulfur particles, and the sulfur particles contained in the air bubbles. The air bubbles are not easy to scale and block, and when the rotating shaft rotates, the impeller rotates in the sleeve, and when the impeller rotates, it can generate a rising thrust to the rich liquid in the sleeve, which is conducive to the flow of the rich liquid cylinder.

3. The present invention is provided with a foaming mechanism. When the transmission mechanism drives the rich liquid in the sleeve to flow, the liquid enters the lower end of the cylinder through the liquid passage on the annular plate, and the liquid at the bottom of the cylinder rises to the circular cylinder through the voltage stabilizer tube. In the tube, the liquid in the round tube rises through the drainage tube and is discharged into the cylinder, thereby forming a circulating flow. Because the throughput of the voltage stabilizer tube is small, the liquid in the cylinder enters the L-shaped tube through the arc tube, and the liquid in the L-shaped tube A large amount of rich liquid enters the circular tube, thereby ensuring the smooth circulation of rich liquid in the cylinder, and due to the special structure of the arc-shaped tube, and the speed of the sulfur particles entering the liquid surface in the cylinder is relatively fast, so the arc-shaped tube is not easy to follow the rich liquid. The liquid enters a large number of sulfur particles, and when the rich liquid passes through the liquid passage on the annular plate, it can take away the sulfur particles and enter the bottom of the cylinder. Because the flow rate of the rich liquid at the bottom of the cylinder is slow, it is conducive to the precipitation of the sulfur particles and facilitates extraction. Sulphur pellets also facilitate maintenance of the regeneration tower.
