Description

Technical Field

[0001] This disclosure relates to the field of wastewater treatment equipment technology, and in particular to an integrated device for efficient gas dosing. Background Technology

[0002] Industrial wastewater, including production wastewater, industrial sewage, and cooling water, refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants lost with the wastewater, resulting in a wide variety of industrial wastewater types and complex compositions. Currently, catalytic oxidation using gaseous sources such as ozone, oxygen, and chlorine dioxide is commonly applied to industrial wastewater, effectively removing recalcitrant substances with low energy consumption. Among these, ozone, oxygen, and chlorine dioxide, as green oxidants, possess characteristics such as high reactivity, good oxidation effect, and no secondary pollution.

[0003] However, the technology for treating recalcitrant substances in industrial wastewater using current wastewater treatment devices is not yet mature enough, resulting in low degradation efficiency and low effective utilization of gas sources, which limits the application of gas-source catalytic oxidation in industrial wastewater treatment. Utility Model Content

[0004] This disclosure provides an integrated device for efficient gas dosing, which at least solves one of the technical problems existing in the prior art.

[0005] According to a first aspect of this disclosure, an integrated device for efficient gas dosing is provided, comprising:

[0006] A reaction apparatus, comprising a reaction chamber and an inlet, an outlet, and a vent connected to the reaction chamber; the inlet is used to connect to a wastewater source, the outlet is used to discharge the treated wastewater supernatant from the reaction chamber into an outlet water tank, and the vent is used to discharge unreacted gas from the reaction chamber.

[0007] An ultra-micro nanobubble generator has a liquid inlet, an air inlet, and a bubble release outlet; the liquid inlet is connected to the reaction chamber, the air inlet is connected to a gas source, and the bubble release outlet is connected to the reaction chamber. The ultra-micro nanobubble generator is used to process the liquid in the reaction chamber with the gas from the gas source to obtain ultra-micro nanobubble water, and to transport the ultra-micro nanobubble water to the reaction chamber of the reaction device.

[0008] In one embodiment, a first pump is further included, which is disposed between the liquid inlet of the ultramicro nanobubble generator and the reaction device, for conveying the liquid in the reaction chamber to the liquid inlet.

[0009] In one embodiment, the device further includes an outlet water tank, which is connected to the outlet of the reaction device via a connecting pipe.

[0010] In one embodiment, the device further includes an exhaust gas treatment device, which is connected to the outlet of the reaction device and is used to treat and discharge unreacted gases.

[0011] In one embodiment, a centrifugal fan is also included, which is connected to the exhaust port of the exhaust gas treatment device.

[0012] In one embodiment, a second pump is also included, which is located on a pipe between the wastewater source and the inlet of the reaction device, for transporting wastewater from the wastewater source to the reaction chamber.

[0013] In one embodiment, a sensor is also included, which is located on the pipe between the second pump and the inlet of the reaction device, and the sensor is used to monitor the water flow rate in the pipe.

[0014] In one embodiment, a gas concentration detector is also included. The gas concentration detector is installed on the pipe between the gas source and the air inlet of the ultra-micro nanobubble generator, and is used to detect the gas concentration and flow rate in the pipe.

[0015] In one possible embodiment, it further includes a pH sensor for real-time monitoring of the pH value of the liquid in the reaction chamber;

[0016] In addition, a redox potential sensor is provided, which is used to monitor the redox potential of the liquid in the reaction chamber in real time.

[0017] Compared with existing technologies, the advantages of this application are as follows: 1) This application uses an ultra-micro nanobubble generator to perform gas-liquid cutting and mixing, allowing the gas from the gas source to be injected into the wastewater in the form of nanobubbles. This increases the gas-liquid contact area, prolongs the contact time with the wastewater, and greatly improves the stability of the gas concentration from the gas source, thereby improving the utilization rate of the gas source and the treatment efficiency of pollutants in the wastewater. For example, the gas source can be an ozone source. Ozone is injected into the wastewater in the form of nanobubbles, resulting in a large gas-liquid contact area and a long contact time. Furthermore, the ozone nanobubbles burst in the wastewater, greatly improving the ozone dissolution efficiency in the wastewater and significantly increasing the ozone water concentration. The nanobubbles can also remain in the water for a long time, greatly improving the stability of the ozone water concentration. The integrated device of this application combines ozone and micro / nanobubbles to generate ozone ultra-micro nanobubble water, thereby improving the solubility of ozone in water and further enhancing the ozone utilization rate.

[0018] 2) This application uses a first pump to circulate the liquid in the reaction device multiple times and then passes it through an ultra-micro nanobubble generator, resulting in smaller nanobubble particle size and higher concentration. This leads to higher utilization of the gas source (such as ozone) and higher concentration of gas in the water (such as ozone), thereby greatly improving the treatment efficiency of pollutants in wastewater.

[0019] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this disclosure, nor is it intended to limit the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0020] The above and other objects, features, and advantages of this disclosure will become readily apparent from the following detailed description of exemplary embodiments, taken in conjunction with the accompanying drawings. Several embodiments of this disclosure are illustrated in the drawings by way of example and not limitation, in which:

[0021] In the accompanying drawings, the same or corresponding reference numerals indicate the same or corresponding parts.

[0022] Figure 1 A schematic diagram of the structure of an integrated device according to an embodiment of the present disclosure is shown. Detailed Implementation

[0023] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] According to one embodiment of this disclosure, such as Figure 1 As shown, this utility model provides an integrated device for efficient gas dosing, comprising:

[0025] The reaction device 4 has a reaction chamber 41 and an inlet 42, an outlet 43 and a gas outlet 44 connected to the reaction chamber 41; the inlet 42 is used to connect to a wastewater source, the outlet 43 is used to discharge the treated wastewater supernatant in the reaction chamber 41 to the effluent tank 6, and the gas outlet 44 is used to discharge unreacted gas in the reaction chamber 41.

[0026] The ultra-micro nano bubble generator 3 has a liquid inlet 31, an air inlet 32, and a bubble release outlet 33. The liquid inlet 31 is connected to the reaction chamber 41, the air inlet 32 ​​is connected to the gas source, and the bubble release outlet 33 is connected to the reaction chamber 41. The ultra-micro nano bubble generator 3 is used to process the liquid in the reaction chamber and the gas from the gas source to obtain ultra-micro nano bubble water, and to transport the ultra-micro nano bubble water to the reaction chamber 41 of the reaction device 4.

[0027] For example, in this embodiment, the gas source includes, but is not limited to, ozone source 2, and can also be other gases, such as oxygen or chlorine dioxide. In this embodiment, the reaction device 4 is a box structure or can be any other structure such as a tower, and has a reaction chamber 41 inside, which is used to provide a reaction site for wastewater treatment. Taking ozone source 2 as an example, this application sets up a reaction device 4, and ozone combines with ultra-micro nanobubbles and mixes better with wastewater in the reaction chamber of the reaction device 4, thereby achieving efficient treatment of recalcitrant pollutants in wastewater.

[0028] For example, in this embodiment, the outlet 43 is located above the inlet 42, and above the connection between the bubble release port 33 and the reaction chamber 41. This allows the ozone ultra-micro nanobubbles to have maximum contact with the liquid in the reaction chamber from bottom to top, thereby improving the wastewater treatment efficiency in the reaction chamber.

[0029] For example, the wastewater source is industrial wastewater, that is... Figure 1 The high-density tank effluent 7 is shown in the diagram. This high-density tank effluent 7 is connected to the inlet 42 of the reaction device 4 via a pipe.

[0030] For example, when the gas source is ozone source 2, ozone source 2 is high-concentration ozone generated on-site. Furthermore, an oxygen generator can be installed to produce oxygen, which, as the gas source for the ozone generator, produces an even higher concentration of ozone. For example, ozone source 2 is connected to the air inlet 32 ​​of the ultra-micro nanobubble generator via pipes, shut-off valves FV001, FV002, FV003, flow meter FI001, check valve FV015, and shut-off valve FV004.

[0031] For example, the ultra-micro nanobubble generator 3 is used to treat the liquid in the reaction chamber 41 with ozone to obtain ozone ultra-micro nanobubble water (i.e., ozone water). The "liquid" includes a mixture of substances such as wastewater, reagents, and nanobubbles transported to the reaction chamber, all contained within the reaction chamber. The liquid and ozone in the reaction device 4 undergo vigorous mixing and separation within the ultra-micro nanobubble generator 3, forming high-concentration ozone water. This high-concentration ozone water can then more efficiently react with the wastewater, significantly improving wastewater treatment efficiency. The supernatant from the treated wastewater is discharged into the effluent tank 6 through the outlet 43.

[0032] This application utilizes an ultra-micro nanobubble generator 3 to perform gas-liquid cutting and mixing. Ozone is injected into the wastewater in the form of nanobubbles, resulting in a large gas-liquid contact area and a long contact time. Furthermore, the ozone nanobubbles burst in the wastewater, greatly improving the ozone dissolution efficiency and increasing the ozone water concentration. The nanobubbles can also remain in the water for a long time, significantly improving the stability of the ozone water concentration and thus enhancing the treatment efficiency of pollutants in the wastewater.

[0033] The integrated device of this application improves the solubility of ozone in water and further enhances the utilization rate of ozone by combining ozone and micro-nano bubbles to generate ozone ultra-micro-nano bubble water.

[0034] Furthermore, the integrated device of this application also includes a first pump 34, which is located between the liquid inlet 31 of the ultra-micro nano bubble generator 3 and the reaction device 4, and is used to transport the liquid in the reaction chamber 41 to the liquid inlet 31.

[0035] For example, the first pump 34 is a circulation pump, which includes, but is not limited to, a submersible pump or a land pump. For example, the circulation pump can be a centrifugal pump. The liquid in the reaction device 4 is circulated through the ultra-micro nanobubble generator 3 multiple times by the first pump 34, so that the nanobubble particle size is smaller and the concentration is higher, so that the utilization rate of the gas source (such as ozone) is higher and the ozone concentration in the water is higher.

[0036] For example, the first pump 34 is connected to the reaction chamber 41 of the reaction device 4 via a pipe, ball valve FV007, and ball valve FV006 connected in series. Alternatively, the first pump 34 can also be connected to the reaction chamber 41 of the reaction device 4 via a pipe, ball valve FV007, and ball valve FV005 connected in series.

[0037] For example, the connection between the bubble release port 33 of the ultra-micro nanobubble generator 3 and the reaction chamber 41 is located below the connection between the first pump 34 and the reaction device 4. The high-concentration ozone water delivered from the bubble release port 3 can enter the reaction chamber 41 from below, fully mixing and reacting with the liquid in the reaction chamber. The ozone water rises from below to above the reaction chamber 41, expanding the gas-liquid contact area and improving wastewater treatment efficiency.

[0038] In some embodiments, the integrated device of this application further includes an outlet water tank 6, which is connected to the outlet 43 of the reaction device 4 via a connecting pipe 61. The wastewater supernatant obtained after the wastewater in the reaction chamber 41 of the reaction device 4 is treated is discharged into the outlet water tank 6 through the outlet 43 and the connecting pipe 61, and then discharged into the drain outlet after the outlet water tank 6 has settled.

[0039] For example, the connecting pipe 61 is a corrugated pipe, and a ball valve FV012 is connected in series on the pipe between the corrugated pipe and the outlet 43.

[0040] In some embodiments, the integrated device of this application further includes an exhaust gas treatment device 51, which is connected to the outlet 44 of the reaction device 4 and is used to treat unreacted gases (such as ozone) before discharging them. Undissolved and escaping ozone in the reaction chamber 41 is discharged through the outlet 44 into the exhaust gas treatment device 51, where it is treated and absorbed by the catalyst in the exhaust gas treatment device 51 and converted into other harmless gases.

[0041] In this application, the exhaust gas treatment device 51 can be a heating type, a catalyst type, or any device capable of absorbing or converting the gas (such as ozone) from the gas source into other harmless substances. This exhaust gas treatment device 51 can be implemented using existing known devices, which will not be elaborated upon here.

[0042] Furthermore, the integrated device of this application also includes a centrifugal fan 52, which is connected to the exhaust port of the exhaust gas treatment device 51. The harmless gas treated by the exhaust gas treatment device 51 is discharged to the outside (outdoors) through the centrifugal fan 52.

[0043] The integrated device of this application, by setting up an exhaust gas absorption system 5 (including an exhaust gas treatment device 51 and a centrifugal fan 52), can treat undissolved and escaping gas sources (such as ozone) before discharging them, thus protecting the environment.

[0044] In some embodiments, the integrated device of this application further includes a second pump 1, which includes, but is not limited to, a pneumatic diaphragm pump. The pneumatic diaphragm pump is located on the pipeline between the wastewater source and the inlet 42 of the reaction device 4, and is used to transport wastewater from the wastewater source to the reaction chamber 41.

[0045] For example, when a pneumatic diaphragm pump is in operation, it works in conjunction with a compressed air system (i.e., Figure 1 The field instruments in the system are connected to the air pump, for example, to the air pump or air compressor.

[0046] Furthermore, the integrated device of this application also includes a sensor, said sensor (such as...) Figure 1 The flow meter FI002 shown is installed on the pipeline between the second pump 1 and the inlet 42 of the reaction device 4. The sensor is used to monitor the water flow rate in the pipeline. When wastewater is not required to be transported, the inlet of the pneumatic diaphragm pump can also be blocked with a ball valve, a check valve, or a plug.

[0047] like Figure 1As shown, the wastewater source is connected to the inlet 42 of the reaction device 4 through a pipeline, ball valve FV008, pneumatic diaphragm pump 1, ball valve FV009, and flow meter FI002. This application uses a second pump 1 (such as a pneumatic diaphragm pump) to pump the wastewater from the wastewater source into the reaction device 4, and uses sensors to control the water level and the inlet flow rate.

[0048] Of course, the wastewater source can also be connected to the reaction device 4 via pipes, ball valves FV008 and FV011. The ball valve FV011 is connected to the bottom of the reaction device 4 to drain the liquid from the reaction chamber, thus returning it to the wastewater source. Alternatively, it can be discharged outside the system for separate collection and treatment.

[0049] In some embodiments, the integrated device of this application further includes a gas concentration detector (such as an ozone concentration detector), which is located on the pipeline between the gas source (such as ozone source 2) and the air inlet 32 ​​of the ultra-micro nanobubble generator, and is used to detect the concentration and flow rate of the gas (such as ozone) in the pipeline.

[0050] Furthermore, the integrated device of this application also includes a pH sensor, which is used to monitor the pH value of the liquid in the reaction chamber 41 in real time;

[0051] In addition, a redox potential sensor is provided, which is used to monitor the redox potential of the liquid in the reaction chamber 41 in real time.

[0052] In addition, the integrated device of this application is equipped with an integrated PLC control system, which is electrically connected to various sensors (such as pH sensors and oxidation-reduction potential sensors). The PLC control system can be manually switched or intelligently automatically controlled.

[0053] This application enables precise control of ozone, reagents, etc. by setting up pH sensors and oxidation-reduction potential sensors.

[0054] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this disclosure can be achieved, and this is not limited herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0056] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
