[0002] With the wide application of the catalytic ozone oxidation process, lightweight catalysts are used more and more widely. During the use of lightweight catalysts, in a conventional bed-type tower, affected by the bed layer, ozone microbubbles in water will converge into larger bubbles after passing through the bed layer, resulting in the tendency of the middle part of the catalyst to aggregate and deposit at the bottom of the bed layer; while the bottom catalyst will aggregate at the top of the bed layer due to the air flotation effect of a large number of microbubbles generated by a large air flow at the bottom; as a result, in practical applications, the lightweight catalyst cannot be evenly distributed in the tower, causing problems of low catalyst utilization rate and low ozone utilization rate.

[0003] Therefore, it is necessary to propose a uniform distribution device for a lightweight ozone catalyst inside a tower to at least partially solve the problems of sedimentation and flotation of the catalyst in the tower in the prior art, so as to achieve the purpose of improving the utilization rates of the catalyst and ozone.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0030] Embodiment

[0031] The following will further describe the present utility model in conjunction with the drawings.

[0032] As Figures 1 - 3 shown, a uniform distribution device for a lightweight ozone catalyst tower provided in this embodiment includes:

[0033] Microbubble aeration pipe group 1, and the microbubble aeration pipe group 1 is arranged at the bottom of the reaction tower;

[0034] The catalytic bed is connected inside the reaction tower and is arranged above the microbubble aeration pipe group 1. The catalytic bed includes an upper catalytic bed 3 and a lower catalytic bed 2 arranged vertically.

[0035] The light catalyst distributor 9 is arranged inside the upper catalytic bed 3. A slant nozzle 904 is rotatably connected to the light catalyst distributor 9.

[0036] The reaction tower includes: a water outlet 4, a circulating water pipe inlet 5, a water inlet 7, and an air inlet 8. The water outlet 4 and the circulating water pipe inlet 5 are arranged on the side surface at the top of the reaction tower. The water inlet 7 is arranged on the side surface at the bottom of the reaction tower. The air inlet 8 is arranged on the side surface at the bottom of the reaction tower and is connected to the microbubble aeration pipe group 1.

[0037] The light catalyst distributor 9 includes: a distributor air inlet 901, a distributor water inlet 902, a rotating shaft 903, and a slant nozzle 904. The distributor air inlet 901 is arranged on the side surface of the light catalyst distributor 9. The distributor water inlet 902 is arranged at the top end of the light catalyst distributor 9. The rotating shaft 903 is rotatably arranged on the light catalyst distributor 9 and is connected to the slant nozzle 904. After the gas and water are mixed inside the distributor 9, they flow out from the slant nozzle 904.

[0038] The slant nozzle 904 is provided with a plurality of them, and the plurality of slant nozzles 904 are evenly arranged along the circumferential direction of the rotating shaft 903.

[0039] The nozzle of the slant nozzle 904 is inclined obliquely downward relative to the center line of the rotating shaft 903.

[0040] The end of the nozzle of the slant nozzle 904 is bent, and the bending directions of the nozzles of the plurality of slant nozzles 904 are the same.

[0041] The distributor water inlet 902 is connected to the circulating water pipe inlet 5 through a pipeline, and a water pump is arranged on the pipeline. The water pump provides power for the flow of the circulating water and adjusts the flow rate.

[0042] The water pump is set as a centrifugal pump.

[0043] The distributor air inlet 901 is communicated with the main pipe of the air inlet 8 through a pipeline. For the ozone gas in the air inlet 8, a part of it flows to the distributor air inlet 901, and a part of it flows to the microbubble aeration pipe group 1. A flow meter 6 is installed on the pipeline to adjust the pipeline flow rate.

[0044] The circulating water inlet flow rate of the light catalyst distributor 9 is set to be 4 to 10 times the air inlet flow rate.

[0045] The working principle of the present utility model is as follows:

[0046] The utility model provides a lightweight catalyst uniform distribution system. When in use, ozone enters a pipeline through an air inlet 8, and after the required flow rate is regulated by a flowmeter 6, it enters a lightweight catalyst distributor 9. The remaining ozone passes through a bottom microbubble aeration pipe group 1, and microbubbles are generated through the aeration pipe group 1 and enter the tower from the bottom. The water inlet of the lightweight catalyst distributor 9 is connected to a circulating water pipeline, and the flow rate into the circulating water pipe is controlled by a water pump in the middle. After the circulating water enters the distributor 9 and is fully mixed with the ozone gas, it flows out through an inclined spray port 904 of the distributor 9. The high-speed flow beam partially flowing out through 904 impacts the bottom catalyst of the lower catalyst bed layer 2 where the floating catalyst accumulates, and the large ozone bubbles that coalesce and pass through the lower catalyst bed layer 2, causing the bottom catalyst of the lower catalyst bed layer 2 to flow reversely to the bottom of the tower, and breaking the large ozone bubbles into small ozone bubbles. The sub-high-speed flow beam partially flowing out through the inclined spray port 904 impacts the catalyst deposited at the contact position between the lower catalyst bed layer 2 and the inner wall of the reaction tower, causing it to float between the lower catalyst bed layer 2 and the upper catalyst bed layer 3.

[0047] When the lightweight catalyst distributor 9 is in use, the high-speed flow beam flows out from the inclined spray port 904, which will push the lower part of the lightweight catalyst distributor 9 to rotate through a rotating shaft 903, so that the flow beam impact force received by the catalyst at the same position at the bottom alternates between strong and weak. The catalyst forms a periodic up-and-down floating between below the lower catalyst bed layer 2 and between the lower catalyst bed layer 2 and the upper catalyst bed layer 3, achieving the purpose of uniform distribution. At the same time, the rotation of the inclined spray port 904 drives the liquid in the tower to rotate in the same direction, improving the uniformity of catalyst distribution.

[0048] The beneficial effects of the utility model are as follows:

[0049] (1) The ozone-containing water mixture sprayed out through the inclined spray port 904 at the bottom of the lightweight catalyst distributor 9 impacts the catalyst floating on the top of the bed layer at the bottom, enabling it to obtain reverse kinetic energy and return to the middle bottom;

[0050] (2) The ozone-containing water mixture sprayed out through the inclined spray port 904 of the lightweight catalyst distributor 9 shatters the large air bubbles formed by coalescence passing through the bed layer, enabling them to reform into small air bubbles, reducing their rising speed, and improving the ozone utilization rate;

[0051] (3) Using the small air bubbles formed by large air bubbles and the small air bubbles formed by the inclined spray port 904 of the lightweight catalyst distributor 9, the catalyst deposited at the bottom in the middle is promoted to be suspended;

[0052] (4) Using the oblique thrust of the inclined spray port 904, the lightweight catalyst distributor 9 is pushed to rotate, driving the liquid in the tower to be disturbed in the same direction, dispersing the catalyst, enabling it to be evenly distributed in the tower, and improving the utilization rate of the catalyst and ozone.

[0054] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here.
