The inclination angle of the baffle plate is too large, the change of the channel direction of the baffle plate is more violent, and the airflow can change the flow direction rapidly, so that the gas-liquid separation efficiency can be improved to a certain degree, but the pressure drop can be increased, the energy consumption of the system is increased, the secondary entrainment phenomenon is easily caused, and finally the separation efficiency is also influenced.
