[0042] This embodiment provides a circulation system, which includes a target device. Preferably, the target device in this embodiment refers to a wet process device having a liquid medicine circulation system.

[0043] At present, in order to improve the relevant key parameters of the liquid medicine, conventional methods such as the self-circulation, bubbling, ultrasonic, megasonic, and overflow of the liquid medicine are mainly adopted. Since the above methods are already relatively mature, there is not much room for improvement at present. Therefore, at a more microscopic level, in this embodiment, a gas-liquid mixing device is connected into the circulation system. The liquid medicine inlet of the gas-liquid mixing device is connected to the inlet of the target device, and the liquid medicine outlet is connected to the discharge port of the target device. Through the gas-liquid mixing device, micro-nano bubbles are evenly mixed into the liquid medicine, improving the activity and uniformity of the liquid medicine and accelerating the reaction rate between the liquid medicine and the workpiece.

[0044] Specifically, as shown in Figure 1-Figure 3 the gas-liquid mixing device of this embodiment includes a body 1, a liquid pipeline 2, a gas pipeline 3, and a control device. The liquid pipeline 2 and the gas pipeline 3 are both arranged inside the body 1. The body 1 is hollow and has four legs at the bottom. One side of the body 1 is set as a door panel through a hinge. By opening or closing the door panel, it is convenient to replace and maintain the pipelines inside the body 1.

[0045] As shown in Figure 1 and Figure 2 one end of the liquid pipeline 2 is a liquid inlet 21, the other end of the liquid pipeline 2 is a liquid outlet 22. The liquid pipeline 2 is integrally arranged in a "C" shape, and the liquid inlet 21 is located above the liquid outlet 22. Define the pipeline in the vertical direction of the liquid pipeline 2 as the vertical section, and the pipeline in the horizontal direction as the horizontal section. A bubble generator 6 is arranged on the vertical section of the liquid pipeline 2. A first flow regulating device for regulating the liquid flow rate and a first pressure monitoring device for monitoring the liquid pressure are also arranged on the liquid pipeline 2.

[0046] One end of the gas pipeline 3 is a gas inlet, the other end of the gas pipeline 3 is a gas outlet. An air flow regulating device for regulating the gas flow rate and a gas pressure monitoring device for monitoring the gas pressure are arranged on the gas pipeline 3. And the gas outlet is connected to the bubble generator 6 so that the bubbles are evenly mixed in the liquid passing through the bubble generator 6.

[0047] In order to achieve automatic control, the control device is electrically connected to the first flow regulating device, the first pressure monitoring device, the air flow regulating device, and the gas pressure monitoring device.

[0048] It can be understood that the liquid medicine whose relevant key parameters need to be improved is introduced into the liquid pipeline 2 from the liquid inlet 21. The first pressure monitoring device monitors the liquid pressure and transmits the monitored pressure signal value to the control device in real time. The control device correspondingly adjusts the liquid medicine flow rate of the first flow device according to the preset pressure value.

[0049] Similarly, gas is introduced into the gas pipeline 3 from the gas inlet, and the gas pressure is monitored by the air pressure monitoring device, and the monitored pressure signal value is transmitted to the control device in real time. The control device adjusts the gas flow of the airflow regulating device accordingly according to the preset pressure value, thereby realizing precise control of the flow and pressure of the liquid medicine and gas. The liquid medicine is mixed with the gas after passing through the bubble generator 6 in the liquid pipeline 2. The micro-nano bubbles mixed into the liquid medicine improve the activity and uniformity of the liquid medicine, accelerate the reaction rate of the liquid medicine and the workpiece, reduce the reaction concentration of the liquid medicine, and improve the yield rate and product performance.

[0050] Preferably, if Figure 2 As shown, the first flow regulating device includes at least a first liquid regulating valve 23, and the airflow regulating device includes a first gas volume regulating valve 31 and a second gas volume regulating valve 32. According to the control signal of the control device, the openings of the first liquid regulating valve 23, the first gas volume regulating valve 31 and the second gas volume regulating valve 32 are automatically adjusted, thereby realizing automatic adjustment of the flow and pressure of the liquid pipeline 2 and the gas pipeline 3, with a high degree of automation.

[0051] In other embodiments, the number of the first liquid regulating valves 23 can be two, three or even more, and the first gas volume regulating valve 31 and the second gas volume regulating valve 32 can also be selectively set as one, or more. This embodiment does not specifically limit the number of their settings.

[0052] Preferably, if Figure 2 As shown, the first pressure monitoring device includes a first pressure gauge 24, and the air pressure monitoring device includes a second pressure gauge 33. The pressure gauges have high measurement accuracy, good indication stability, can accurately reflect pressure changes, have simple structural design, are easy to use and maintain, and can work stably for a long time.

[0053] In order to adapt to a larger flow of liquid medicine, to match the circulation speed of the circulation system. Figure 3 As shown, the gas-liquid mixing device also includes a diversion pipeline 4, and one or more diversion pipelines 4 are provided. In this embodiment, one is provided, and in other embodiments, two, three, four or even more can be provided. The specific number can be set according to actual needs.

[0054] Specifically, one end of the shunt line 4 is connected to the liquid inlet 21, and the other end of the shunt line 4 is connected to the liquid outlet 22. When the shunt line 4 is in an open state, the medicinal liquid flows in from the liquid inlet 21, and can pass through the shunt line 4 and then enter the horizontal section below the liquid line 2, and finally flow upward to reach the bubble generator 6, or it can directly enter the horizontal section above the liquid line 2, and finally flow downward to reach the bubble generator 6, thereby realizing the diversion of the medicinal liquid to adapt to a larger flow of medicinal liquid, and has strong adaptability.

[0055] Further, see Figure 3 The shunt line 4 is provided with a second flow regulating device for regulating the liquid flow and a second pressure monitoring device for monitoring the liquid pressure, which are electrically connected to the control device. The second flow regulating device includes at least a second liquid regulating valve 41, and the second pressure monitoring device includes a third pressure gauge 42. By adjusting the opening and closing of the second liquid regulating valve 41, or adaptively adjusting the opening of the liquid medicine through the shunt line 4.

[0056] In order to avoid frequently installing or removing the gas-liquid mixing device from the circulation device when the gas-liquid mixing device is not needed. Figure 3 As shown, the gas-liquid mixing device further includes a branch pipeline 5. An opening and closing device electrically connected to the control device is provided on the branch pipeline 5 and the liquid pipeline 2. The opening and closing device is used to adjust the opening / closing of the branch pipeline 5 and / or the liquid pipeline 2. Specifically, the opening and closing device includes a first control valve 25, a second control valve 26, and a third control valve 51. The first control valve 25 and the second control valve 26 are provided on the liquid pipeline 2 and are located at the front and rear ends of the bubble generator 6, respectively. The third control valve 51 is provided on the branch pipeline 5.

[0057] When the gas-liquid mixing device is needed, the third control valve 51 is closed, and the first control valve 25 and the second control valve 26 are opened. At this time, the liquid medicine can be mixed with the gas through the bubble generator 6;

[0058] When the gas-liquid mixing device is not needed, the first control valve 25 and the second control valve 26 are closed, and the third control valve 51 is opened. At this time, the liquid medicine will be directly discharged into and discharged through the branch pipe 5 and will not pass through the bubble generator 6.

[0059] In addition, a liquid leakage sensor 11 is provided on the inner bottom wall of the body 1, and a liquid leakage discharge valve 12 is provided at the bottom end of the body 1. The liquid leakage sensor 11 and the liquid leakage discharge valve 12 are electrically connected to the control device. When liquid leakage occurs in each pipeline and the medicine flows to the bottom of the body 1, the liquid leakage sensor 11 senses the leakage and immediately sends a signal to the control device. The control device controls the liquid leakage discharge valve 12 to open, thereby directly discharging the leaked liquid at the bottom, thereby protecting the electrically charged equipment inside the body 1.

[0060] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
