Device for simulating mutual collision of bubbles and liquid drops

The invention relates to a device for simulating mutual collision of bubbles and liquid drops, which comprises a bubble generating device, a liquid drop generating device, a circulating pipeline, a temperature control device and an image acquisition device, and is characterized in that the bubble generating device and the liquid drop generating device are connected through the circulating pipeline, and the temperature control device is arranged outside the circulating pipeline; and the image acquisition device is arranged on the circulating pipeline. In simulation, the particle sizes and collision frequencies of bubbles and liquid drops are controlled by adjusting a connecting needle head and flow of an injection pump, so that the collision conditions of the bubbles and the liquid drops in different particle size ratios under different collision frequencies at different temperatures and different deviation angles of a vertical pipeline are simulated; the collision process of the bubbles and the liquid drops i
