The utility model discloses a reaction tail gas pressure measurement and control device, and belongs to the technical field of chemical production devices and reaction tail gas effective control. The device comprises a tail gas main pipeline, a reaction kettle, an air regulating valve, a U-shaped differential pressure gauge, an airflow damper and the like. The first innovation point is that when the weak pressure of the tail gas pipeline is measured, the conversion thinking concept of the water-based U-shaped differential pressure gauge is introduced, the problem that the weak positive pressure or negative pressure in the tail gas pipeline is difficult to measure due to the large measuring range of a common pressure gauge or vacuum gauge is effectively solved, and then effective regulation and control are implemented; and the second innovation point is that the airflow damper is additionally arranged at the tail gas outlet of the reaction kettle, so that the gas-liquid entrainment phenomenon can be effectivel
