Description

Technical Field

[0001] The present invention relates to the field of oxygen-enriched ozone tail gas treatment, and in particular to a device for recycling oxygen-enriched ozone tail gas. Background Art

[0002] With economic development, wastewater composition is becoming increasingly complex, and the requirements for water quality treatment are becoming increasingly stringent. Ozone, due to its strong oxidizing properties, is widely used in wastewater treatment for decolorization, COD removal, and disinfection. Traditional ozone processes play a vital role in wastewater treatment. Their powerful oxidizing capacity effectively removes organic matter, pathogens, and some difficult-to-degrade substances from wastewater, significantly improving water quality. However, while this process efficiently treats wastewater, it also comes with a significant challenge: the generation of large amounts of oxygen-rich ozone exhaust gas.

[0003] In addition to incompletely reacted ozone molecules, these exhaust gases are also rich in oxygen transferred from wastewater or newly generated. Existing treatment methods mostly discharge these exhaust gases directly. However, directly releasing these exhaust gases into the atmosphere without proper treatment is not only a huge waste of precious resources, but can also cause a series of adverse impacts on the environment and cause secondary pollution. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a device for recycling and utilizing oxygen-enriched ozone tail gas.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The vents are located on the top of the vent and are connected to the vent pipe, and the vent pipe is connected to the vent pipe at the bottom of the vent pipe. The cooling tube has a bottom end portion and a bottom end portion, and a cooling tube has a bottom end and a bottom end portion, and a cooling tube has a bottom end and a bottom end portion.

[0007] In the above-mentioned device for recovering and recycling oxygen-rich ozone tail gas, the conversion box is fixedly installed on the inner side of the separation tank, and the three cooling boxes are rotatably installed on the inner side of the separation tank. The conversion box is located directly above the three cooling boxes. A connecting bearing is fixedly installed at the center of the conversion box, and the rotating shaft is fixedly installed on the inner side of the connecting bearing.

[0008] In the above-mentioned device for recovering and recycling oxygen-rich ozone tail gas, the three Stirling refrigerators are each provided with two output ends, one of the output ends of the three Stirling refrigerators is respectively connected to the inner side of the three collecting boxes, and the other output ends of the three Stirling refrigerators pass through the side wall of the separation tank and extend to the inner side of the cooling chamber through the arc groove. The temperatures output by the output ends of the three Stirling refrigerators are -120°C, -140°C and -160°C respectively.

[0009] In the above-mentioned device for recovering and recycling oxygen-rich ozone tail gas, the end of the liquid ozone outlet pipe away from the collecting box is fixed through the outer wall of the separation tank and extends to the interior of the separation tank. The sealing frame ring is located on the inner side of the separation tank, and the tops of the three sealing frame rings are respectively in contact with the bottoms of the three cooling boxes.

[0010] In the above-mentioned device for recovering and recycling oxygen-rich ozone tail gas, the conversion pipe is located between the blocking plugs installed at the top and bottom of the conversion box, the top of the cooling pipe is connected to the inlet hole, and the bottom of the converging pipe is connected to the outlet hole.

[0011] In the above-mentioned device for recycling and recovering oxygen-enriched ozone tail gas, a convergence groove is provided on the top of each of the three cooling boxes, and the inlet hole is located at the bottom of the inner cavity of the convergence groove.

[0012] In the above-mentioned device for recycling and recovering oxygen-enriched ozone tail gas, the arc-shaped rod is slidably mounted on the inner side of the circular groove, and the magnetic poles of the opposing surfaces of the second magnetic ring and the first magnetic ring are the same.

[0013] In the above-mentioned device for recycling oxygen-rich ozone tail gas, support legs are fixedly installed on the bottom of the separation tank. There are four support legs, and the four support legs are symmetrically distributed in a rectangular shape at the four corners of the bottom of the separation tank.

[0014] Compared with existing technologies, the advantages of this device for recycling and utilizing oxygen-enriched ozone tail gas are:

[0015] 1. The oxygen-rich ozone tail gas can enter the interior of the separation tank through the oxygen discharge pipe, and then after being processed by the conversion component and the stepped cooling separation component inside the separation tank, part of the ozone in the oxygen-rich ozone tail gas can be converted into oxygen, and the remaining ozone in the tail gas can be cooled and liquefied into liquid ozone, thereby separating the ozone and oxygen in the oxygen-rich ozone tail gas. The oxygen is finally discharged through the oxygen discharge pipe, which is convenient for the separation and recovery of ozone and oxygen, and convenient for subsequent recycling. It can achieve efficient recovery, deep purification and convenient recycling of the oxygen-rich ozone tail gas, effectively reducing resource waste and environmental pollution;

[0016] 2. When the oxygen-rich ozone tail gas passes through the conversion pipe, the ozone inside it can be accelerated to convert into oxygen under the irradiation of infrared and ultraviolet rays emitted by the infrared lamp column and the ultraviolet lamp column, thereby improving the oxygen collection rate and oxygen recovery effect in the oxygen-rich ozone tail gas and improving the use effect of the device. In addition, the converted tail gas will be discharged through the ventilation groove opened on the inner side of the shielding plug at the bottom of the conversion box, and move to the bottom of the inner cavity of the separation tank under the promotion of airflow;

[0017] 3. The oxygen-rich ozone exhaust gas will enter the cooling pipe inside the cooling box through the inlet hole. When the oxygen-rich ozone exhaust gas passes through the cooling pipe and the bent pipe, the ozone contained in it will be liquefied due to the temperature, and the liquefied ozone will converge into the converging pipe. In addition, since the cooling temperature of the three Stirling refrigerators is stepped after startup, the liquefaction effect of the ozone can be improved, the ozone content in the final exhaust oxygen can be greatly reduced, and the use effect of the device can be improved.

[0028] An oxygen-rich ozone tail gas supply pipe can be connected to the oxygen exhaust pipe 7, and the oxygen-rich ozone tail gas can enter the interior of the separation tank 1 through the oxygen exhaust pipe 7. Then, after being processed by the conversion component and the stepped cooling separation component inside the separation tank 1, part of the ozone in the oxygen-rich ozone tail gas can be converted into oxygen, and the remaining ozone in the tail gas can be cooled and liquefied into liquid ozone, thereby separating the ozone and oxygen in the oxygen-rich ozone tail gas, and the oxygen is finally discharged through the oxygen exhaust pipe 7, which is convenient for separating and recovering ozone and oxygen, and convenient for subsequent recycling.
