Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and specifically to a device for purifying ozone and recovering oxygen. Background Art

[0002] With the acceleration of the industrialization process, the problem of environmental pollution has become increasingly prominent. In particular, the problem of air pollution has become the focus of global attention. As an air pollutant, ozone damages the ecological environment. At the same time, due to its characteristics of low exposure risk but high health risk, it poses a threat to human health.

[0003] In the prior art, the patent with the patent number CN 107166573B is a technology for purifying and recovering ozone. It uses catalysts including silver oxide, copper oxide, manganese oxide, etc. to decompose ozone into oxygen and directly discharge it into the air. This technology has the problem that the catalyst is easily adsorbed by water molecules and deactivated. The patent with the patent number CN 203170300 U discloses a honeycomb cordierite ozone decomposition catalytic converter, and the efficiency of eliminating ozone by this physical adsorption method is relatively low.

[0004] However, in the prior art, methods for removing ozone indoors, such as activated carbon adsorbents, not only have low adsorption efficiency and long purification cycles, but also the activated carbon will reach a saturated state after adsorbing a certain amount of ozone and needs to be replaced with new activated carbon regularly. This not only increases the operating cost but also generates the problem of waste treatment. Summary of the Invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] A device for purifying ozone and recovering oxygen includes a metal shell 1 as the outer protective layer of the entire device. An air inlet 2 is installed on one side of the metal shell 1. Inside the metal shell 1, an air pump 3, a heating device 4, and an ozone catalyst-loaded oxygen molecular sieve 5 are arranged horizontally. Among them, the air inlet 2, the air pump 3, the heating device 4, and the ozone catalyst-loaded oxygen molecular sieve 5 are connected in sequence;

[0035] The ozone catalyst-loaded oxygen molecular sieve 5 is used to quickly decompose ozone and generate oxygen through the ozone catalyst-loaded oxygen molecular sieve 5. The heating device 4 is used to heat the air to be purified to 100 - 120 °C to evaporate the water vapor in the air and avoid the inactivation of the catalyst on the ozone catalyst-loaded oxygen molecular sieve 5 caused by the adsorption of water molecules.

[0036] Such as Figure 1 、 Figure 2, the air inlet 2, the air pump 3, the heating device 4, and the ozone catalyst-loaded oxygen molecular sieve 5 are all connected channels. Among them, one end of the heating device 4 close to the ozone catalyst-loaded oxygen molecular sieve 5 has an openable and closable door (not shown in the figure). When heating, the door is closed, and after heating is completed, the door is opened.

[0037] An ozone sensor 6 is installed on the metal shell 1. The ozone sensor 6 is electrically connected to the air pump 3 and is used to monitor the ozone concentration in the air and trigger the air pump 3 when the ozone concentration reaches the set value.

[0038] Such as Figure 1 , the ozone sensor 6 is a prior art that can monitor the ozone concentration in the air, and no more details will be described here.

[0039] A gas discharge pipe 7 and a gas booster pump 8 are connected to the ozone catalyst-loaded oxygen molecular sieve 5. An oxygen tank 9 is installed inside the metal shell 1. The gas booster pump 8 is connected to the oxygen tank 9 and is used to pressurize and transport oxygen into the oxygen tank 9. One end of the gas discharge pipe 7 extends to the outside of the metal shell 1.

[0040] Such as Figure 1 , after ozone is decomposed by the ozone catalyst-loaded oxygen molecular sieve 5, oxygen passes through the ozone catalyst-loaded oxygen molecular sieve 5, while other gases cannot pass through the ozone catalyst-loaded oxygen molecular sieve 5 and are discharged to the outside of the metal shell 1 through the gas discharge pipe 7.

[0041] The ozone catalyst-loaded oxygen molecular sieve 5 is an ozone catalyst loaded on an oxygen molecular sieve. Among them, the preparation method of the ozone catalyst is as follows:

[0042] The first step: Place the oxygen molecular sieve in a muffle furnace at 400 °C and calcine for 2 h;

[0043] The second step: Place the calcined carrier in a manganese nitrate solution (Mn(NO 3 ) 2 , 50%) for 8 h, then dry in a muffle furnace at 200 °C for 2 h and calcine at 400 °C for 2 h to obtain substance A;

[0044] The third step: Place substance A in iron(III) nitrate nonahydrate (Fe(NO 3 ) 2 ·9H 2 O) for 8 h, then dry in a muffle furnace at 200 °C for 2 h and calcine at 400 °C for 2 h to obtain substance B;

[0045] The fourth step: Place substance B in copper(II) nitrate trihydrate (Cu(NO 3 ) 2 ·3H 2O) Bake at 80 °C for 8 hours, then dry in a muffle furnace at 200 °C for 2 hours, calcine at 400 °C for 2 hours, and cool to obtain the ozone decomposition catalyst.

[0046] Such as Figure 1 , the catalyst filling amount on the ozone catalyst-loaded oxygen molecular sieve 5 is 0.5 - 3 m 3 , ozone with a concentration of 0.01 - 20 ppm can be decomposed into oxygen, ensuring that the residence time of the gas in the chamber where the ozone catalyst-loaded oxygen molecular sieve 5 is located is ≥ 3 s, the gas flow rate is 0.26 - 0.48 m / s, the purified air speed is 0.16 - 0.95 m3 / s, the decomposition efficiency under this working condition is 94% - 98%, and the service life of this working condition reaches 1 - 2 years.

[0047] The heating device 4 includes a tubular container 11 with a mesh heating wire inside. The top of the tubular container 11 is connected to an arc-shaped cover 12. A condensation chamber 13 is formed between the arc-shaped cover 12 and the tubular container 11. The top of the tubular container 11 is fixedly connected to a communication nozzle 14, and the communication nozzle 14 is used to connect the condensation chamber 13 and the arc-shaped cover 12.

[0048] Such as Figure 2 And Figure 3 , both ends of the arc-shaped cover 12 are closed. Only a part is shown in the figure, so that a closed space is formed inside the arc-shaped cover 12. There is a mesh heating wire in the tubular container 11 in the prior art, which can heat the air in the tubular container 11.

[0049] A servo motor 19 is fixedly connected to the outside of the condensation chamber 13. The output end of the servo motor 19 is fixedly connected to a large winding disc 20 and a small winding disc 21.

[0050] Such as Figure 2 , the servo motor 19 is externally powered and is provided with a corresponding control switch outside. It realizes automatic control through a program. The radius of the large winding disc 20 is larger than that of the small winding disc 21, so that after the large winding disc 20 and the small winding disc 21 rotate the same number of turns, the winding length of the large winding disc 20 on the second movable pull rope 29 exceeds the winding length of the small winding disc 21 on the first movable pull rope 18, increasing the stroke when the second movable rope 29 pulls the power rack 27.

[0051] A diversion pipe 15 is fixedly connected to the bottom of the condensation chamber 13. A sealing sleeve 16 is fixedly connected to the middle of the diversion pipe 15. A tension spring is fixedly connected to the inner wall of the sealing sleeve 16. One end of the tension spring is fixedly connected to a movable plug 17. A first movable pull rope 18 is fixedly connected to the movable plug 17. One end of the first movable pull rope 18 bends upward and is fixedly connected to the small winding disc 21.

[0052] Such as Figure 3 And Figure 4, the movable plug 17 can block the diversion pipe 15. One end of the sealing sleeve 16 has an upwardly bent sleeve, and the first movable pull rope 18 passes through the sleeve, providing guidance for the first movable pull rope 18 while reducing the friction generated by bending the first movable pull rope 18.

[0053] A support frame is fixedly connected inside the tubular container 11. One side of the support frame is rotatably connected with a power gear 23, and one side of the power gear 23 is fixedly connected with a fan blade 24;

[0054] Such as Figure 2 and Figure 4 , the fan blade 24 is composed of three fan-shaped components and can rotate together with the power gear 23.

[0055] A guide rod 25 is fixedly connected inside the tubular container 11. A sliding plate 26 is slidably connected to the guide rod 25. The bottom of the sliding plate 26 is fixedly connected with a power rack 27. The power rack 27 meshes with the power gear 23. A return spring 28 is sleeved on the guide rod 25. One end of the return spring 28 is fixedly connected with the sliding plate 26. One end of the sliding plate 26 is fixedly connected with a second movable pull rope 29. One end of the second movable pull rope 29 sequentially passes through the tubular container 11, the arc-shaped cover 12 and is fixedly connected with the large winding disc 20.

[0056] Such as Figure 2 and Figure 5 , the cross-section of the guide rod 25 is a regular hexagon, which can ensure the horizontal movement of the sliding plate 26 and the power rack 27.

[0057] An electromagnetic valve 22 is installed at the bottom of the diversion pipe 15. One side of the diversion pipe 15 and above the electromagnetic valve 22 is fixedly connected with a conduction air pipe 221. One end of the conduction air pipe 221 extends into the interior of the tubular container 11.

[0058] Such as Figure 2 and Figure 3 , the conduction air pipe 221 extends from the bottom of the tubular container 11 to the interior of the tubular container 11.

[0059] The working principle of a device for purifying ozone and recovering oxygen provided by the present invention is as follows:

[0060] First, an ozone sensor is used to monitor the ozone concentration in the air. When the monitored ozone concentration reaches a preset threshold, the air pump 3 is triggered. The air pump 3 sucks the air to be purified through the air inlet 2 into the heating device 4. The sucked gas is first heated to 100 - 120 °C. At this temperature, the water vapor in the gas is evaporated, avoiding the inactivation of the catalyst caused by the adsorption of water molecules, and the ozone decomposition rate is increased at this temperature.

[0061] The gas to be purified passes through the ozone catalyst-loaded oxygen molecular sieve 5 and is decomposed to release oxygen. After being pressurized by the gas pressure pump, the pure oxygen is stored in the oxygen tank 9 for further use;

[0062] When ozone enters the inner part of the tubular container 11 in the heating device 4 for heating, the steam generated by heating will enter the inner part of the condensation chamber 13 through the connecting nozzle 14. After being condensed inside the condensation chamber 13, the liquid droplets will drip inside the condensation chamber 13 and finally flow into the position above the sealing sleeve 16 in the diversion pipe 15;

[0063] After the liquid droplets have accumulated for a period of time, the servo motor 19 can be started. The servo motor 19 drives the large winding disc 20 and the small winding disc 21 to rotate counterclockwise, winding up the first movable pull rope 18 and the second movable pull rope 29. At this time, the first movable pull rope 18 drives the movable plug 17 to move horizontally, and the water above the movable plug 17 drops, squeezing the air inside the diversion pipe 15 below the movable plug 17, so that the air enters the inner part of the tubular container 11 through the conducting air pipe 221 and generates an upward air flow inside the tubular container 11;

[0064] At the same time, the second movable pull rope 29 pulls the power rack 27, driving the power gear 23 and the fan blade 24 to rotate, generating an air flow in the horizontal direction inside the tubular container 11. Finally, the solenoid valve 22 is opened to drain the water in the diversion pipe 15, and the servo motor 19 rotates clockwise to release the first movable pull rope 18 and the second movable pull rope 29. Under the action of the reset spring 28 and the tension spring, the power rack 27 and the movable plug 17 are reset.

[0065] Compared with the related technology, a device for purifying ozone and recovering oxygen provided by the present invention has the following beneficial effects:

[0066] First, by loading the ozone decomposition catalyst on the oxygen molecular sieve and circulating the indoor air into the heating device 4 through the air pump 3, the present invention can continuously remove ozone in the indoor air and convert it into oxygen for storage, achieving more efficient elimination of ozone. No waste is generated during the process of eliminating ozone, thus realizing the dual goals of environmental protection and resource recovery.

[0067] Second, by providing the diversion pipe 15 and the condensation chamber 13, collecting the steam droplets generated by evaporation, and utilizing the characteristic of the liquid droplets flowing downward, when the servo motor is started, vertical and horizontal air flows are generated inside the tubular container 11 at the same time, enhancing the fluidity of the air inside the tubular container 11, so that the air inside the tubular container 11 can be heated more quickly and fully and the water vapor can be evaporated.

[0068] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
