Abstract

This invention relates to an experimental detection device and method for simulating the flow field inside an electrolytic cell, comprising: an upper end cover assembly, a lower end cover, an electrode plate, a clamping assembly, a monitoring component, a gas input component, and a liquid input component. The upper end cover assembly is provided with an air inlet. The electrode plate is disposed between the upper end cover assembly and the lower end cover, and the electrode plate is provided with a liquid inlet and a liquid outlet. The clamping assembly is used to fix the upper end cover assembly, the electrode plate, and the lower end cover. The gas input component is connected to the air inlet and is used to input gas into the internal space between the upper end cover assembly and the electrode plate. The liquid input component is connected to the liquid inlet, and liquid enters into the internal space between the lower end cover and the electrode plate. The gas input component can control the bubble formation rate by adjusting the gas pressure to simulate the state of bubble generation inside the electrolytic cell. The monitoring component is used to record the distribution, aggregation, and discharge of bubbles in the internal space formed by the electrode plate and the lower end cover.
