[0001] The utility model belongs to the technical field of hydrogen peroxide treatment, and in particular relates to a hydrogen peroxide removal device. Background Art

[0002] In the process of removing hydrogen peroxide, the method of decomposing hydrogen peroxide is usually adopted. After decomposition, hydrogen peroxide will form water and oxygen. During the actual decomposition, the existing technology evacuates the oxygen into the atmosphere through aeration in the aeration tank to avoid the accumulation of oxygen in the water or the device.

[0003] The shortcomings of the existing technology are that the aeration tank is usually set up in a flat manner in the decomposition site, which requires a large space and has low space utilization. In addition, the hydrogen peroxide in the tank is in a concentrated state during decomposition, resulting in the oxygen generated by the decomposition cannot be discharged in a timely and effective manner, and the discharge efficiency is low.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, a hydrogen peroxide removal device includes a tower body 1, a water outlet 2 is provided on one side of the bottom of the tower body 1, an air inlet 3 is provided above the water outlet 2, an air equalizing plate 4 is fixedly connected above the air inlet 3 inside the tower body 1, an air mixing layer 5 is provided on the top of the air mixing layer 5, a support frame 6 is provided on the top of the support frame 6, and a multi-layer filter element 7 is placed on the top of the support frame 6, ten support rods 8 are evenly fixedly connected along the inner wall of the top of the tower body 1, a water equalizing tank 9 is fixedly connected between the inner ends of each support rod 8, a water mixing layer 10 is provided between the water equalizing tank 9 and the filter element 7 on the adjacent side, a water inlet pipe 11 is fixedly connected to one side of the water equalizing tank 9, the water inlet pipe 11 passes through the tower body 1 and extends to the outside of the tower body 1, an exhaust pipe 12 is installed on the top of the tower body 1, and a blower 13 is installed on one side of the air inlet 3;

[0025] It should be noted that air holes 14 are evenly arranged on the surface of the air equalizing plate 4; the support frame 6 is welded by steel bars arranged vertically and horizontally, and its installation method includes but is not limited to being fixedly connected to the inside of the tower body 1. Preferably, the support frame 6 can be overlapped on the support ring by welding a supporting ring on the inner wall of the tower body 1. The structure of the support frame 6 can ensure that both water flow and air flow pass smoothly, and has the function of supporting the filter element 7; the filter element 7 is preferably a hollow ball made of plastic, and the surface is smooth to facilitate the formation of a water film.

[0026] like Figure 1 and Figure 2 As shown, the tower body 1 is provided with an air observation window 15 at the same level as the air mixing layer 5, and a water observation window 16 at the same level as the water mixing layer 10;

[0027] It should be noted that the air observation window 15 and the water observation window 16 are both fixedly connected to transparent glass. After the blower 13 transports the air into the tower body 1, the air equalizing plate 4 above evenly transports the transported air upward to the mixed water layer 5. The staff can observe the air flow inside the tower body 1 through the air observation window 15. At the same time, after the water inlet pipe 11 fills the water equalizing tank 9 with water, the water flows into the mixed water layer 10. The staff can observe the water intake delivered to the inside of the tower body 1 through the water observation window 16, that is, observe the water replenishment and aeration conditions of the degassing process through the air observation window 15 and the water observation window 16, and adjust the water intake and air intake according to the specific situation.

[0028] like Figure 2 and Figure 4 As shown, the water tank 9 includes a water storage tank 91 fixedly connected to each support rod 8, a plurality of water spray heads 92 are evenly installed at the bottom of the water storage tank 91, and a large number of water spray holes are evenly arranged on the bottom surface of the water spray head 92. The water inlet pipe 11 is connected to the interior of the water storage tank 91;

[0029] It should be noted that after the water inlet pipe 11 injects hydrogen peroxide containing some residual oxygen into the water storage tank 91, this water is sprayed out by multiple water spray heads 92 installed at the bottom. Since a large number of water spray holes are provided at the bottom of the water spray heads 92, the water can be further dispersed, thereby increasing the contact area between the water droplets and the air and improving the gas exchange rate with the air.

[0030] An air ring 17 is provided between the side surface of the water storage tank 91 and the inner wall of the tower body 1 . The gas transported from the bottom of the tower body 1 rises from the bottom to the top through the air ring 17 to the top of the tower body 1 and is finally discharged through the exhaust pipe 12 .

[0031] Example 2:

[0032] The filter element 7 is preferably a hollow sphere with dense small pores evenly distributed on the surface, and a variety of catalytic fillers are mixed inside the sphere, with iron oxide, manganese oxide and titanium oxide as the main components. Therefore, after the hydrogen peroxide in the water passes through the filter element 7, it will be decomposed into water and oxygen under the action of the catalyst, thereby achieving the decomposition of the hydrogen peroxide in the water.

[0033] The working principle of this utility model:

[0034] In the process of treating oxygenated hydrogen peroxide (hereinafter referred to as water body), the staff first installs the blower 13 at the air inlet 3 on one side of the bottom of the tower body 1, and then starts the blower 13. At the same time, the valve of the water inlet pipe 11 on the top of the tower body 1 is opened to inject water into the water equalization tank 9. The water falls to the mixed water layer 10 through the various water spray heads 92 of the water equalization tank 9. At this time, the water body is dispersed into fine water droplets. At the same time, due to the continuous blowing of the blower 13 from bottom to top, the water droplets are further dispersed into smaller water droplets. Then, these water droplets fall to the multi-layer filter element 7. Since the filter element 7 is a hollow plastic ball with a smooth surface, the water droplets form a flowing film on its surface after falling. Then the gas in the water body is in close contact with the air brought by the blast. Since the oxygen concentration in the water body is greater than the oxygen concentration in the air, and since gas molecules have a diffusion effect of moving from high concentration to low concentration, the oxygen in the water film will diffuse into the air, thereby achieving the effect of removing oxygen from the water body.

[0035] In addition, since the air from bottom to top is first evenly dispersed through the air-diffusion plate 4, and then in a uniform state when moving upward through the mixed air layer 5 and the support frame 6, the uniformity of the contact with the falling water is improved. At the same time, the high-pressure upward airflow slows down the falling speed of the thin film of water, creating sufficient time for gas diffusion, thereby providing sufficient, uniform and long-term diffusion conditions for the gas diffusion process, thereby improving the oxygen removal effect.

[0036] Since there are still gaps between the filter elements 7, the water film continues to fall from the gaps to the bottom of the tower body 1 until it is discharged from the water outlet 2. At the same time, the air carrying the diffused and exchanged oxygen continues to rise through the air ring 17 to the exhaust pipe 12 for discharge.

[0037] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
