Description

Technical Field

[0001] This utility model belongs to the field of high-concentration brine treatment, specifically an ozone catalytic oxidation pretreatment device for high-concentration brine. Background Technology

[0002] The treatment of high-concentration brine has always been a thorny issue in industrial production and daily life. High-concentration brine contains a large amount of inorganic salts and organic matter. If it is discharged directly or treated without proper treatment, it will cause serious environmental pollution. In order to prevent this from happening, ozone catalytic oxidation technology is used to treat high-concentration brine.

[0003] When using ozone catalytic oxidation technology to treat high-concentration brine, the strong oxidizing properties of ozone, under the action of a catalyst, generate active species such as hydroxyl radicals with even stronger oxidizing capabilities. These can rapidly attack and oxidize the organic matter and some inorganic matter in the water, converting them into small molecules or completely mineralizing them, thereby achieving the purpose of purifying the water quality. However, in actual use, the inorganic salt components in high-concentration brine may affect the decomposition of ozone and the activity of the catalyst, reducing the treatment efficiency. At the same time, the high viscosity and density of high-concentration brine are not conducive to the full contact and reaction between ozone and organic matter, thus reducing the treatment quality of high-concentration brine.

[0021] Example 1

[0022] like Figure 1-4As shown, this is the first embodiment of the present invention. This embodiment provides an ozone catalytic oxidation high-concentration brine pretreatment device, including an ozone input unit 1. A reaction processing unit 2 is arranged behind the ozone input unit 1. The reaction processing unit 2 includes a reaction tank 21. A tank cover 22 is provided on the top of the reaction tank 21, and a reaction component 23 is provided at the lower end of the inner cavity of the tank cover 22. A processing component 24 is provided at the upper end of the inner cavity of the reaction tank 21. The processing component 24 includes a reduction motor 241, and a screw 242 is drivenly connected to the output shaft of the reduction motor 241. A stirring plate 243 is fixedly connected to the bottom of the screw 242. A movable disk 244 is threadedly connected to the surface of the screw 242. Electric heating tubes 245 are fixedly connected to both sides of the bottom of the tank cover 22. The movable disk 244 is located on the surface of the electric heating tubes 245 and is slidably connected to the surface of the electric heating tubes 245. A microcontroller 4 is provided on the surface of the reaction tank 21, and a temperature sensor 3 is provided on the inner wall of the reaction tank 21.

[0023] like Figure 1-4 As shown, ozone can be evenly distributed into the reaction tank 21 through the ozone input unit 1, allowing the ozone to fully contact the high-concentration brine. Simultaneously, in conjunction with the reaction component 23, reactive species such as hydroxyl radicals with stronger oxidizing capabilities can be generated. These reactive species can rapidly attack and oxidize the organic matter and some inorganic matter in the water, converting them into small molecules or completely mineralizing them, thus achieving the treatment of high-concentration brine. During the treatment process, the reaction temperature is monitored in real time by a microcontroller 4 and a temperature sensor 3.

The WS700, through the microcontroller 4, controls the operation of the heating element 245 to regulate the reaction temperature inside the reaction vessel 21, thereby providing the optimal working temperature environment for the catalyst and further improving its activity. Simultaneously, the design of the geared motor 241, screw 242, stirring blade 243, and movable disc 244 in the processing component 24 enables effective stirring and mixing of high-concentration brine, overcoming the viscosity and density limitations of high-concentration brine. The sliding connection design of the stirring blade 243 and movable disc 244 makes the stirring process more uniform, promoting full contact and reaction between ozone and organic matter, thus improving the treatment quality of high-concentration brine.

[0024] Example 2

[0025] Reference Figure 1 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] In this embodiment, the ozone input unit 1 includes a base frame 11, an oxygen tank 12 is provided on the left side of the top of the base frame 11, and an ozone generator 13 is provided on the top of the base frame 11. A connecting pipe 14 connects the oxygen tank 12 and the ozone generator 13. The outlet end of the ozone generator 13 is connected to a gas supply pipe 15. The other end of the gas supply pipe 15 extends into the inner cavity of the reaction tank 21 and is connected to a gas distribution pipe 16. The top of the gas distribution pipe 16 is connected to an aeration disc.

[0027] A delivery pump 25 is fixedly connected to the right side of the top of the base frame 11. The water outlet of the delivery pump 25 is connected to a water supply pipe 26. The other end of the water supply pipe 26 is connected to the tank cover 22 and communicates with the inner cavity of the reaction tank 21. The water inlet of the delivery pump 25 is connected to an external high-concentration brine source.

[0028] like Figure 1 and 3 As shown, the combination of oxygen tank 12 and ozone generator 13 can continuously and stably generate ozone. Oxygen can be easily transferred to ozone generator 13 through connecting pipe 14. The use of gas supply pipe 15, gas distribution pipe 16 and aeration disc ensures that ozone can be efficiently and without damage transferred to reaction tank 21, and that ozone is evenly distributed in reaction tank 21, improving the contact efficiency between ozone and wastewater. The operation of transfer pump 25 and water supply pipe 26 can stably transfer external high-concentration brine to reaction tank 21, providing a continuous source of raw materials for the reaction.

[0029] Example 3

[0030] Reference Figure 2-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0031] In this embodiment, the reaction assembly 23 includes a perforated support plate, a crushed stone layer, and a catalyst layer. The perforated support plate is fixedly connected to the inner wall of the reaction vessel 21, the crushed stone layer is located above the perforated support plate, and the catalyst layer is located above the crushed stone layer.

[0032] The top of the tank cover 22 is connected to an exhaust pipe 221, and the other end of the exhaust pipe 221 is connected to an external waste gas collection tank. The upper end of the surface of the reaction tank 21 is connected to a water outlet pipe 222.

[0033] The microcontroller 4 has a display screen on its front side, and the input terminal of the display screen is connected to the output terminal of the microcontroller 4. The input terminal of the microcontroller 4 is connected to the output terminal of the temperature sensor 3. The output terminal of the microcontroller 4 is connected to the input terminals of the delivery pump 25, the heating element 245 of the ozone generator 13, and the geared motor 241, respectively.

[0034] like Figure 2-4As shown, the perforated support plate in the reaction assembly 23 supports the crushed stone layer and the catalyst layer, which can perform preliminary pretreatment of the high-concentration brine and provide the necessary catalytic effect for the ozone catalytic oxidation reaction. The exhaust pipe 221 introduces the waste gas or unreacted ozone generated during the reaction into an external waste gas collection tank for treatment, avoiding environmental pollution. The design of the water outlet pipe 222 allows the treated wastewater to be easily discharged from the reaction tank 21 and enter the subsequent treatment process or be reused. The microcontroller 4 serves as the control core, which is connected to the temperature sensor 3, the delivery pump 25, the ozone generator 13, the electric heating tube 245, and the geared motor 241, thereby realizing intelligent control of the entire treatment process. At the same time, it can receive the temperature data monitored by the temperature sensor 3 and transmit the temperature data to the display screen for display, which facilitates timely feedback information for the operator.

[0035] In operation, the microcontroller 4 first controls the delivery pump 25 to work with the water pipe 26 to transfer high-concentration brine from the outside to the inner cavity of the reaction tank 21. The gravel layer and catalyst layer inside the reaction tank 21 perform preliminary filtration and catalytic action on the wastewater, creating conditions for the subsequent ozone catalytic oxidation reaction. Next, the temperature sensor 3 monitors the temperature inside the reaction tank 21, and the monitored temperature data is transmitted to the microcontroller 4 for analysis. If the temperature value is lower than the preset value, the microcontroller 4 will activate the electric heating tube 245 to generate heat and control the reaction temperature inside the reaction tank 21, thereby providing the optimal working temperature environment for the catalyst and further improving the catalyst activity. At the same time, the microcontroller 4 will activate the geared motor 241, which will drive the screw 242 to rotate. During the rotation of the screw 242, the stirring plate 243 will rotate and the movable disc 244 will move up and down. This movement of the stirring plate 243 and the movable disc 244 will further enhance the reaction process. The aeration disc 244 is used to stir and mix the high-concentration brine, breaking the viscosity and density limitations of the brine and making it uniform. This facilitates the full contact and reaction between ozone and organic matter in the later stages. Then, the ozone generator 13, model PDX-50A, is turned on by the microcontroller 4. Oxygen from the oxygen pipe 12 enters the ozone generator 13 through the connecting pipe 14 and generates ozone under the action of a high-voltage electric field. The generated ozone is then evenly distributed into the inner cavity of the reaction tank 21 through the gas supply pipe 15 and the gas distribution pipe 16. The aeration disc further enhances the ozone dispersion effect, allowing the ozone to fully contact the high-concentration brine. At the same time, in conjunction with the reaction component 23, active species such as hydroxyl radicals with stronger oxidizing power can be generated, which can quickly attack and oxidize and decompose organic matter and some inorganic matter in the water, converting them into small molecules or completely mineralizing them. This achieves the treatment of high-concentration brine and effectively improves the treatment quality.
