Baffle type cyclone demister

Abstract

The invention provides a baffle type demisting device combining inertial separation and cyclone centrifugal separation and a method thereof. The method is as follows: the demisting device is designed as a two-level demister, and when airflow passes through a channel arranged between demisting blades of a first-level baffle on the base layer, mist drops impact the blades under the inertia effect due to flow line deflection, thereby realizing capture of large-diameter droplets. In addition, the outlet section of the baffle is arranged obliquely and faces one rotating direction, thereby achieving the functions of both demisting and diversion, so that the airflow can rise in a rotating way when passing through the first-level blades. The channel of a second-level demister is of deflection type in the vertical direction and is of a concentric ring shape in the horizontal direction, so that when rotating airflow passes through the demisting channel on the layer, smaller mist drops can be further removed under the combined effect of the baffle inertia separation and the rotating centrifugal separation, thereby making the whole demister achieve the effect of completely demisting.

Description

technical field [0001] The invention relates to a device and method for a baffle inertial separation-cyclone centrifugal separation composite demister, and belongs to the technical field of air pollution prevention and control. Background technique [0002] In the industrial production process, the demister device is usually used to remove the liquid droplets entrained in the gas, so as to reduce the pollution and corrosion of the liquid droplets on the airflow channel and subsequent equipment, or to prevent the direct discharge of the mist-containing gas from polluting the atmospheric environment. Its basic working principle is that when the airflow with liquid droplets enters the channel of the demister, under the action of various forces, the movement direction of the droplets deviates from the direction of the airflow, and makes it hit the demister blade or other On the surface of the collector, it can be removed, so as to realize the separation of gas and liquid.
