Description

Technical Field

[0001] This utility model relates to the field of ozone preparation technology, and more specifically, to an oxygen recovery device that separates ozone and oxygen to generate high-concentration ozone. Background Technology

[0002] Ozone has extremely strong oxidizing properties and can quickly kill bacteria, viruses, fungi and other microorganisms. In drinking water treatment, ozone is used as a disinfectant, which can effectively remove bacteria, viruses and other harmful substances from the water and provide a safe drinking water source.

[0003] Chinese patent application CN202323132899.6 discloses an oxygen and ozone mixed gas separation device, specifically relating to the field of environmental protection. The device includes a housing, a heat exchanger, and a gas-liquid filter screen disposed within the housing. The heat exchanger includes heat exchange tubes, at least two input ends, and three output ends. The two ends of the heat exchange tubes are respectively the first input end and the first output end. The mixed gas flows through the heat exchange tubes from the second input end. The resulting gaseous oxygen is output from the second output end, which is located at different ends of the heat exchange tubes. Liquid ozone is output from the third output end, which is disposed at the bottom of the housing. The gas-liquid filter screen is disposed between the heat exchange tubes and the second output end.

[0004] In the above technical solution, the gas-liquid filter screen is set between the heat exchanger and the third output end. When the fine liquid droplets entrained in the gas pass through the gas-liquid filter screen, the droplets come into contact with the filter screen and are adhered or adsorbed. After repeated adsorption of droplets, the extremely small droplets agglomerate and coalesce into larger droplets. Under the action of gravity, the droplets move downwards along the intersection of the woven wires of the mesh, while continuing to adsorb droplets entrained in the gas. The larger droplets flow to the bottom of the gas-liquid filter screen and fall down by their own gravity, outputting liquid ozone from the third output section. However, this device only performs a single separation, and the separated oxygen may still contain ozone. Furthermore, the separated oxygen is not returned to the raw material silo for reuse, resulting in a waste of raw materials. Utility Model Content

[0005] The purpose of this invention is to provide an oxygen recovery device that separates ozone and oxygen to generate high-concentration ozone, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An oxygen recovery device that separates ozone and oxygen to generate high-concentration ozone includes a base. Multiple sets of support components are fixed to the top surface of the base. An ozone generator, a first adsorption tower, a buffer tank, a second adsorption tower, and an oxygen treatment tank are sequentially supported on the support components, all connected by gas guide pipes. A valve is fixed at the inlet end of each gas guide pipe. A two-way valve is fixed at the inlet end of the gas guide pipe between the second adsorption tower and the oxygen treatment tank, and an ozone outlet pipe is fixed to one of its valve ports. A liquid storage tank is fixed to the top surface of the base.

[0008] By adopting the above technical solution, the first adsorption tower and the second adsorption tower achieve two separations of the mixed gas of oxygen and ozone separated by the ozone generator, further purifying the ozone. The buffer tank stabilizes the oxygen after passing through the first adsorption tower, and the oxygen treatment tank is connected to the ozone generator through a gas guide pipe, thereby sending the treated oxygen back to the ozone generator for recycling and avoiding waste of raw materials.

[0009] Preferably, the support assembly includes multiple support frames fixed at equal angles to the top surface of the base, and the ends of the support frames are fixedly connected with fixing hoops.

[0010] Preferably, the oxygen treatment tank has an internal cavity, and a coolant pipe is coiled inside the cavity. The inlet and outlet ends of the coolant pipe are respectively fixedly connected to the outlet pipe and inlet pipe that are fixedly extended from the storage tank.

[0011] By adopting the above technical solution, the coolant in the storage tank is transported to the coolant pipe in the cavity through the outlet pipe, thereby exchanging heat and cooling the oxygen in the oxygen treatment tank, thereby reducing its viscosity, accelerating the flow, and speeding up the subsequent reaction process.

[0012] Preferably, both the first adsorption tower and the second adsorption tower are equipped with molecular sieves.

[0013] Preferably, the gas delivery pipes are all connected from the bottom of the ozone generator, the first adsorption tower, the buffer tank, the second adsorption tower, and the oxygen treatment tank to the top of the next tank.

[0014] By adopting the above technical solution, since both ozone and oxygen will sink, the gas duct is set at the bottom for outlet.

[0015] Preferably, guide vanes are fixedly installed at the bends of the inner wall of the air duct.

[0016] By adopting the above technical solution, the guide vanes guide the gas flow, which can reduce turbulence and energy loss at the bends of the gas pipe.

[0017] Preferably, a fan is fixed to the top surface of the base at the bend of the air duct, and an air outlet pipe is fixed to the fan and extends into the interior of the air duct.

[0018] By adopting the above technical solution, the blower can provide additional power to push the gas through the gas pipe faster, and can also avoid insufficient gas power preventing it from entering the next tank.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1) By setting up the first and second adsorption towers, the ozone and oxygen mixture can be purified multiple times through pressure swing adsorption to increase ozone production. The gas guide pipe between the second adsorption tower and the oxygen treatment tank is equipped with a two-way valve, which can export the separated oxygen and ozone separately. The oxygen is exported to the oxygen treatment tank and then returned to the ozone generator, thereby realizing the recovery and utilization of oxygen, thereby reducing raw material waste and lowering costs.

[0021] 2) The oxygen treatment tank has an internal cavity. Cooling liquid is discharged into the cooling pipe through the liquid outlet pipe on the liquid storage tank, thereby exchanging heat with the oxygen in the oxygen treatment tank, lowering its temperature, reducing its viscosity, accelerating the flow, and speeding up the subsequent reaction process.

[0027] Example 1

[0028] Please see Figures 1 to 4 An oxygen recovery device that separates ozone and oxygen to generate high-concentration ozone includes a base 1. Multiple support components are fixed to the top surface of the base 1. The support components sequentially support an ozone generator 2, a first adsorption tower 3, a buffer tank 4, a second adsorption tower 5, and an oxygen treatment tank 6, all connected by gas guide pipes 7. A valve 8 is fixed at the inlet end of each gas guide pipe 7. A two-way valve 9 is fixed at the inlet end of the gas guide pipe 7 between the second adsorption tower 5 and the oxygen treatment tank 6, and an ozone outlet pipe is fixed to one of its valve ports. 10. A liquid storage tank 11 is fixed on the top surface of the base 1. The support assembly includes multiple support frames 12 fixed at equal angles to the top surface of the base 1. A fixing hoop 13 is fixedly connected to the end of the support frame 12. The first adsorption tower 3 and the second adsorption tower 5 perform two separations of the mixed gas of oxygen and ozone separated by the ozone generator 2, further purifying the ozone to increase the ozone production. The valve 8 can be opened after the pressure swing adsorption is completed to discharge the unadsorbed oxygen. The adsorbed ozone can be discharged and collected through the ozone outlet pipe 10 after the pressure reduction release.

[0029] The oxygen treatment tank 6 has an internal cavity 14, and a coolant pipe 15 is coiled inside the cavity 14. The inlet and outlet ends of the coolant pipe 15 are fixedly connected to the outlet pipe 16 and inlet pipe 17, which are fixedly extended from the storage tank 11, respectively. The coolant pipe 15 is coiled inside the cavity 14 of the oxygen treatment tank 6. The coolant flowing in the coolant pipe 15 exchanges heat with the oxygen inside, thereby cooling the oxygen, reducing its viscosity, accelerating its flow, and speeding up the subsequent reaction process.

[0030] The steps of using this utility model are as follows: After the oxygen discharged from the second adsorption tower 5 enters the oxygen treatment tank 6, the liquid storage tank 11 delivers coolant to the coolant pipe 15 through the liquid outlet pipe 16. The coolant pipe 15 is coiled in the cavity 14 inside the oxygen treatment tank 6, which can exchange heat and cool the oxygen in the oxygen treatment tank 6, thereby reducing its viscosity, accelerating the flow, and speeding up the subsequent reaction process.

[0031] Example 2

[0032] Please see Figures 1 to 4 Both the first adsorption tower 3 and the second adsorption tower 5 are equipped with molecular sieves. The molecular sieves are crystalline structures that are resistant to ozone oxidation and readily adsorb ozone gas. The molecular sieves are composed of silicates, silicon dioxide, alumina and other composite metal oxides.

[0033] The gas duct 7 is connected from the bottom of the ozone generator 2, the first adsorption tower 3, the buffer tank 4, the second adsorption tower 5 and the oxygen treatment tank 6 to the top of the next tank. Since ozone and oxygen will sink, they are discharged from below.

[0034] Guide vanes are fixedly installed at the bends of the inner wall of the air duct 7. Fans 18 are fixedly installed on the top surface of the base 1 at the bends of the air duct 7. An air outlet pipe 19 is fixed on the fan 18 and extends into the interior of the air duct 7. When the gas passes through the bends of the air duct 7, the guide vanes can guide the gas flow direction, reducing turbulence and energy loss at the bends of the air duct 7. The fan 18 can provide additional power to push the gas through the air duct 7 faster, and can also prevent the gas from being unable to enter the next tank due to insufficient power.

[0035] The steps of using this utility model are as follows: After the mixed gas of ozone and oxygen passes through the pressure swing adsorption of the first adsorption tower 3 and the second adsorption tower 5, the unadsorbed oxygen will enter the oxygen treatment tank 6 through one of the valve ports of the double-way valve 9. After heat exchange treatment, it can be guided back to the ozone generator 2 through the gas guide pipe 7, thereby realizing the recycling of oxygen and achieving the effect of reducing costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
