Active coke wind screening device for desorption tower

An active coke wind screening device for a desorption tower is installed at the joint of an outlet and an inlet of two chain bucket machines and comprises an inner barrel, an outer barrel, a feeding hopper and a discharging hopper, the feeding hopper is installed at the top of the inner barrel, a spherical middle distributor is arranged in the inner barrel, an air outlet is formed in the upper portion of the inner barrel, and a spiral blade set forming an inverted conical surface is arranged on the lower portion of the inner barrel; the outer cylinder is sleeved on the lower portion of the inner cylinder, the discharging hopper is arranged on the lower portion of the outer cylinder, and the outer cylinder is provided with an air inlet. The active coke screening device has the advantages that the feeding hopper, the spherical middle distributor and the discharging hopper are respectively wrapped with a layer of buffer rubber pad, so that friction and collision of active coke in the screening process can be eff
