Chemical tail gas absorption device with intelligent pressure regulation and adsorption functions

The invention relates to the technical field of chemical tail gas absorption, in particular to a chemical tail gas absorption device with an intelligent pressure regulating adsorption function, the chemical tail gas absorption device comprises a base, an absorption tower and a fan, and the absorption tower is arranged above the base. Whether an area for guiding chemical tail gas is blocked or not is detected through the pressure regulating assembly, the amount of tail gas sucked by the draught fan is controlled according to the blocking degree, and the situation that the chemical tail gas absorption device is shut down once the blocking phenomenon occurs, so that workers have no loose time to shut down equipment in a chemical workshop is avoided through the pressure regulating assembly. The device is further provided with a packing disc and a third motor, on one hand, viscous impurities in the tail gas are prevented from being attached to packing, and on the other hand, absorption liquid is prevented from bei
