Abstract

This invention discloses a flow-type acid erosion device considering gravity, comprising: a replenishment tank, a replenishment pipe, a solution tank, a control valve, a drive circulation device, a suction pipe, a flow meter, a dripping device, a dripping plate, a return pipe, and a multi-parameter real-time monitoring device. After the acid solution is prepared, it is replenished from the replenishment pipe into the solution tank via the replenishment tank. The multi-parameter real-time monitoring device is activated to monitor the pH, concentration, and temperature of the solution in real time. Subsequently, the control valve is opened, and the drive circulation device is activated to drive the solution from the suction pipe through the flow meter into the dripping device, dripping onto the dripping plate, and then onto the specimen for reaction. The reacted solution flows back to the solution tank through the return pipe, completing one cycle of erosion. This invention mainly uses a drive circulation device to automatically extract the solution to the dripping device, and then allows it to drip from the dripping plate onto the specimen under gravity for reaction, effectively simulating the erosion process of actual engineering structures by acidic rock solutions, thus enhancing the consistency between indoor experiments and actual engineering.
