Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of catalytic ozone oxidation equipment, in particular to a device for breaking the gas film on the surface of a lightweight ozone catalyst. Background Art
[0002] With the wide application of the catalytic ozone oxidation process, the lightweight ozone catalyst is more and more widely used. The lightweight ozone catalyst uses lightweight materials as carriers or skeletons, such as porous ceramics, lightweight metals or new nanomaterials, etc. These materials have low density and high specific surface area, which is beneficial to the dispersion of the ozone catalyst and the loading of active components. During the use of the lightweight ozone catalyst, due to the influence of water quality characteristics, especially in the treatment of high-concentration organic wastewater, high-salt wastewater and other wastewaters, a gas film is often formed on the surface of the ozone catalyst to wrap around the catalyst, causing it to lose its catalytic function and resulting in the catalyst floating and aggregating at the top of the bed layer, leading to poor treatment effect and a significant decrease in the utilization rate of the catalyst and ozone. Summary of the Utility Model
[0003] The utility model provides a device for breaking the gas film on the surface of a lightweight ozone catalyst, aiming to solve the problem of gas film wrapping around the catalyst and achieve the efficient utilization of the catalyst and ozone.
[0004] To solve the above technical problems, the utility model discloses a device for breaking the gas film on the surface of a lightweight ozone catalyst, including:
[0005] An ozone oxidation tower, with a water outlet opened on the top side and a water inlet opened on the bottom side;
[0006] An ultrasonic generating system, which is arranged outside the ozone oxidation tower;
[0007] An ozone bubble generating system, which is arranged inside the ozone oxidation tower;
[0008] A catalyst bed group, which is arranged inside the ozone oxidation tower and above the ozone bubble generating system.
[0009] Preferably, the ultrasonic generating system includes two ultrasonic generators, and the two ultrasonic generators are symmetrically arranged outside the ozone oxidation tower, and the ultrasonic waves emitted by the ultrasonic generators are conducted to the catalyst bed group inside the ozone oxidation tower.
[0010] Preferably, the ozone bubble generating system is a microbubble aeration disk.
[0011] Preferably, the catalyst bed group includes an upper catalyst bed baffle and a lower catalyst bed baffle, and an ozone catalyst is arranged between the upper catalyst baffle and the lower catalyst bed baffle; vibration rod groups are respectively arranged on the lower surface of the upper catalyst bed baffle and the upper surface of the lower catalyst bed baffle.
[0012] Preferably, the ozone catalyst is a light magnetic ozone catalyst.
[0013] Preferably, the catalyst bed group further includes at least one middle baffle of the catalyst bed, and the middle baffle of the catalyst bed is arranged between the upper baffle of the catalyst and the lower baffle of the catalyst bed; vibrating rod groups are respectively arranged on the upper and lower surfaces of the middle baffle of the catalyst.
[0014] Preferably, the catalyst bed group includes 2 middle baffles of the catalyst bed.
[0015] Preferably, the vibrating rod group includes a plurality of vibrating rods, and each vibrating rod includes a vertical rod and 2-5 inclined rods arranged on the vertical rod.
[0016] Preferably, the vibrating rod is a magnetic vibrating rod, and an anti-corrosion plastic soft package is attached to the outside of the magnetic vibrating rod.
[0017] Preferably, the included angle between the inclined rod and the vertical rod is 30-60°.
[0018] The technical solution of the present utility model has the following advantages:
[0019] 1. Magnetic vibrating rods are built into the bed layers. By magnetically adsorbing the light magnetic catalyst on the surface, its movement form tends to gather around the vibrating rods rather than the top of the bed layer.
[0020] 2. Through the ultrasonic generator, the vibration frequency is transmitted to the baffle, and then from the baffle to the vibrating rods, so that the vibrating rods tap the surface of the catalyst at a high frequency and with a light force to break the surface gas film. At the same time, the broken gas film is re-formed into small bubbles under the disturbance of the vibrating rods, enabling the ozone therein to be reused, thereby improving the utilization rate of the catalyst and the utilization rate of ozone.
[0021] 3. In the device, the bubbles form a cyclic periodic change of "attachment → fragmentation → dissociation → attachment → fragmentation" on the surface of the catalyst, greatly improving the effective utilization rate of ozone and the effective utilization rate of free radicals, and greatly improving the treatment effect.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.
[0030] Embodiment 1
[0031] As Figure 1-2 shown, a device for breaking the gas film on the surface of a light ozone catalyst includes: an ozone oxidation tower, an ultrasonic generating system, an ozone bubble generating system, and a catalyst bed group. An outlet 8 is opened on the top side of the ozone oxidation tower, and an inlet 9 is opened on the bottom side; the ultrasonic generating system includes two ultrasonic generators, namely a first ultrasonic generator 3 and a second ultrasonic generator 10. The ultrasonic generating frequency range of the ultrasonic generator is 1*10 12 ~6*10 12Hz, and two ultrasonic generators are symmetrically arranged outside the ozone oxidation tower. The ultrasonic generators emit ultrasonic waves that are conducted to the catalyst bed group inside the ozone oxidation tower; the ozone bubble generation system is a microbubble aeration disk 1, which is arranged inside the ozone oxidation tower; the catalyst bed group is arranged inside the ozone oxidation tower and is located above the ozone bubble generation system; the catalyst bed group includes a catalyst upper baffle 7 and a catalyst lower baffle 2, and an ozone catalyst is arranged between the catalyst upper baffle 7 and the catalyst lower baffle 2. This ozone catalyst is a lightweight magnetic ozone catalyst; a vibration rod group is respectively arranged on the lower surface of the catalyst upper baffle 7 and the upper surface of the catalyst lower baffle 2. The vibration rod group includes several vibration rods 5. Each vibration rod includes a vertical rod 501 and two inclined rods 502 arranged on the vertical rod. The inclined rods 502 face upward, and the included angle between the inclined rods 502 and the vertical rod 501 ranges from 45°. The vibration rods are made of magnetic materials, and the outside of the vibration rods is attached with an anti-corrosion plastic soft package.
[0032] The working principle and beneficial effects of the above technical solution are as follows: When a lightweight ozone catalyst surface gas film breaking system is in use, ozone forms microbubbles through the microbubble aeration disk 1 and then enters the device. During the upward movement of the microbubbles, they come into contact with the lightweight ozone catalyst, adhere to the surface of the catalyst, and form a gas film-wrapped state. By the frequency generated by the ultrasonic generating system 10, the magnetic vibration rods 5 on the catalyst upper baffle 7, the catalyst lower baffle 2, the catalyst middle baffles 4 and 6 are driven to vibrate, and the gas film on the surface of the lightweight magnetic catalyst enriched around the vibration rods 5 by magnetism is broken. In addition, by driving the vibration rods 5 to vibrate through the ultrasonic generator, and cooperating with the magnetic attraction between the lightweight magnetic catalyst and the magnetic vibration rods, the catalyst can perform a transverse simple harmonic motion around the vibration rods 5, achieving the purpose of contacting and breaking the gas film and uniform distribution.
[0033] Embodiment 2
[0034] On the basis of the above Embodiment 1, as Figure 3 shown, the catalyst bed group further includes two catalyst bed middle baffles, namely the first catalyst bed middle baffle 4 and the second catalyst bed middle baffle 6. The two catalyst bed middle baffles are arranged between the catalyst upper baffle and the catalyst lower baffle, and divide the catalyst bed group into three catalyst bed layers; vibration rod groups are respectively arranged on the upper and lower surfaces of the catalyst middle baffles.
[0035] The working principle and beneficial effects of the above technical solution are as follows: When the static height of the catalyst filled in the catalyst bed group is relatively thick, two catalyst bed middle baffles can be selectively added between the catalyst upper baffle and the catalyst lower baffle to divide the catalyst bed group into three catalyst bed layers, and there are vibration rod groups on the upper and lower surfaces of each bed layer. Through reasonable setting, the contact breaking efficiency of the vibration rods on the surface of the catalyst is increased, thereby improving the utilization rate of the catalyst and the utilization rate of ozone.
[0036] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
