Abstract

The utility model belongs to the technical field of bubbling reaction equipment, specifically a bubbling reaction equipment based on gas-liquid dual control, including a reaction tower, wherein an annular tube is provided on the lower side of the inner wall of the reaction tower. A reversing valve is controlled to connect the air inlet pipe and the annular tube, and the air inlet pipe supplies chlorine gas into the annular tube, which is sprayed out through the air holes on the conical disk and reacts with the liquid. Since the conical disk is arranged in an annular shape on the annular tube, air can be supplied from multiple places, and multiple air holes can improve the reaction rate and uniformity. When the transmission shaft drives the stirring blade to stir the liquid, the rotating plate rotates under the drive of the water flow, and the rotating plate can create a complex flow path, break the layered structure of the liquid, promote uniform mixing, and is not easy to generate vortices, which is convenient for the gas and liquid to fully contact and mix. The reversing valve is controlled to connect the circulation pipe and the annular tube, and the air inlet pipe stops supplying air. The air pump is started to extract the gas that has not fully reacted through the exhaust pipe, and the gas is re-supplied through the circulation pipe for reaction, and the bubbling reaction effect is better.
