Abstract

The invention belongs to a material discharging device with air distribution function, and relates to a material discharging device. The invention solves the problem that the prior material discharging device has no air distribution function; after an axial air distribution device is additionally arranged in a reactor of a moving bed, the moving smoothness of the solid reactants is influenced, and the reactor of the moving bed is blocked. One circular surface of a wind distribution cavity is provided with a plurality of first through holes in uniform distribution. The wind distribution cavity is arranged in an inner cavity of a barrel body in the radial direction, and the outer diameter thereof is equivalent to the inner diameter of the barrel body. A rotary shaft orderly penetrates through a first shaft sleeve, the wind distribution cavity and a second shaft sleeve, and is separately rotatably connected with the first shaft sleeve and the second shaft sleeve. The wind distribution cavity is fixedly connected with the rotary shaft. One end of the rotary shaft is provided with a long blind hole in the axial direction. Both side walls of the rotary shaft in the wind distribution cavity are provided with a plurality of second through holes in uniform distribution. The long blind hole is communicated with the wind distribution cavity through the second through holes. The invention realizes material discharging without obstacle and uniform wind distribution in the reactor of the moving bed, and the material after reaction can be discharged out of the reactor smoothly.

Description

technical field [0001] The invention relates to a discharge device, in particular to a discharge device for a moving bed reactor, belonging to the field of chemical environmental protection. Background technique [0002] In the field of chemical and environmental protection, the moving bed reactor is a common gas-solid reaction device. During the reaction process, the solid-phase reactant is continuously sent into the moving bed reactor through the feeding device, and the solid-phase reactant reacts with the gas entering the reactor from the bottom or upper part of the reactor. The reacted solid phase material is sent to the next process through the discharge valve. In this process, on the one hand, it is necessary to ensure that the reacted material can be smoothly discharged from the bed into the next process, and on the other hand, it is also necessary to ensure that the gas entering the reactor can fully contact with the material to complete the reaction. At present, d...
