Detailed Description
The technical scheme in the utility model is further described in detail below with reference to the accompanying drawings.
The utility model discloses a microbubble content detector, referring to fig. 1, electrolyzed water in an electrolytic tank 601 in the drawing flows out and then enters a separator 603 for separation, hydrogen or oxygen obtained by separation is sent to subsequent treatment equipment, and a circulating pump 602 returns the electrolyzed water flowing out from the separator 603 to the electrolytic tank 601 again.
In some examples, referring to fig. 1, the microbubble content detector includes a transition pipe 11, a detection pipe 12, a detection tank 13, a negative pressure tank 14, a first electromagnetic switch valve 21, a second electromagnetic switch valve 22, a pressure sensor 23, and a pressure adjustment module 3. The transition pipe 11 is installed on a circulation pipe of the electrolytic water in the electrolytic tank, for example, one section of the circulation pipe can be removed, then the transition pipe 11 is used for replacement, and two ends are connected by using flanges.
Both ends of the detection pipe 12 are connected to the transition pipe 11, essentially in a parallel manner. The detection box 13 is arranged on the detection pipeline 12, and a first electromagnetic switch valve 21 is arranged at the joint of the detection box 13 and the detection pipeline, and the first electromagnetic switch valve 21 is used for realizing automatic opening and automatic closing.
The negative pressure tank 14 is connected with the detection tank 13, and is used for reducing the gas pressure in the detection tank 13, then the micro bubbles in the electrolyzed water in the detection tank 13 can be separated, the separated micro bubbles can change the gas pressure in the negative pressure tank 14, and the change can be sensed by the pressure sensor 23 on the negative pressure tank 14.
The second electromagnetic switch valve 22 is installed at the connection between the detection tank 13 and the negative pressure tank 14, and functions the same as the first electromagnetic switch valve 21, and will not be described here again. The pressure regulating module 3 is connected with the negative pressure tank 14 and is used for increasing and decreasing the pressure in the negative pressure tank 14.
Taking a specific detection process as an example:
the first electromagnetic on-off valve 21 is first opened, and at this time, part of the electrolyzed water flows into the check box 13 (shown in fig. 2) through the transition pipe 11 and the check pipe 12, and the air pressure in the negative pressure box 14 is reduced during this process. Then, the first electromagnetic switch valve 21 is closed, the second electromagnetic switch valve 22 is opened, the gas in the detection tank 13 starts to enter the negative pressure tank 14, and the micro bubbles in the electrolyzed water in the detection tank 13 also enter the negative pressure tank 14 (shown in fig. 3), so that the pressure value in the negative pressure tank 14 rises.
The amount of microbubbles in the electrolyzed water can be estimated from the magnitude of the change in the pressure value in the negative pressure tank 14, and it is, of course, necessary to fix the amount of the electrolyzed water that enters the detection tank 13 and the opening time of the second electromagnetic opening/closing valve 22 in the process.
After the detection is completed, the second first electromagnetic switch valve 21 is opened, the pressure regulating module 3 drives the pressure in the negative pressure tank 14 to rise, and the electrolyzed water in the detection tank 13 is returned to the circulating pipeline through the transition pipeline 11, as shown in fig. 4. And sending the detected data to a controller of the electrolytic tank as a basis for adjusting the flow speed of the circulating water.
In some examples, the detection box 13 is provided with a one-way exhaust valve 24, and the one-way exhaust valve 24 is used for exhausting gas in the detection box 13 in the process of flowing the electrolyzed water into the detection box 13, so that the automatic stop of the flowing process of the electrolyzed water caused by the rising of the air pressure is avoided.
Further, a liquid level sensor 25 is further added on the detection box 13, and the liquid level sensor 25 is used for detecting the liquid level in the detection box 13, so that quantitative control of inflow of electrolyzed water is realized.
In some examples, the height of the detection tank 13 is 10% -20% of the length of the detection tank 13 or the width of the negative pressure tank 14, so as to obtain the lowest possible water depth or the greatest possible water surface, so that the micro-bubbles can be quickly separated from the electrolyzed water.
In some examples, the input end of the detection box 13 is located at the side of the detection box 13, and the output end of the detection box 13 is located at the bottom surface of the detection box 13, so that the electrolytic water in the detection box 13 can flow out entirely. Meanwhile, in order to ensure the accuracy of the detection result, a purging module 4 is further added, and the purging module 4 is used for realizing the air drying of residual moisture in the detection box 13 by means of flowing air.
Referring to fig. 5, the purge module 4 includes a blower 41, an air supply duct 42, and an on-off valve 43, the air supply duct 42 is connected with the output end of the blower 41 and the detection box 13, and the on-off valve 43 is installed on the air supply duct 42. When air drying is required, the switch valve 43 is opened, the fan 41 is started, and dry air is fed into the detection box 13, and at this time, the air in the detection box 13 flows out through the one-way exhaust valve 24.
It should be appreciated that the automated detection process above requires the assistance of a controller, which may be a programmable logic controller, such as a PLC. The data detected by the pressure sensor 23 is sent to the main controller of the electrolytic cell through a data signal line, or the pressure sensor 23 can directly use a pressure transmitter. Of course, the main controller of the electrolytic cell can also be an upper computer of the controller in the microbubble content detector disclosed by the utility model.
