Embodiment Construction
[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0032] Such as figure 1 As shown, the present invention provides a moving bed flue gas purification device. The moving bed flue gas purification device includes a tower body, and the tower body is provided with an air inlet area 1, a first purification area 21, The flue area 3, the second purification area 22 and the gas outlet area 4, the flue gas can enter the first purification area 21 from the intake area 1 in a countercurrent manner, and can enter the second purification area from the flue area 3 in a cross-flow manner. District 22. The moving bed flue gas purification device of the present invention combines the adsorption processes of cross-flow and counter-current, and has the advantages of sufficient contact between the flue gas of the counter-current process and the purification zone (ie,...

The invention belongs to the technical field of flue gas purification and discloses a movable bed flue gas purification device. The movable bed flue gas purification device comprises a tower body, wherein the tower body is internally provided with a gas inlet region, a first purification region, a flue region, a second purification region and a gas outlet region in sequence along a flue gas flowing direction; and flue gas can enter the first purification region from the gas outlet region in a counter flow manner and can enter the second purification region from the flue region in a cross flowmanner. The movable bed flue gas purification device disclosed by the invention integrates cross flow and counter flow adsorption technologies, has the advantage that flue gas of a counter flow technology is in sufficient contact with the purification region and also has the advantage that the resistance in the purification region of a cross flow technology is small; compared with a pure counter flow technology, the device has the advantages off small flue gas resistance, simple structure and low operation cost; compared with a pure cross flow technology, the flue gas is in sufficient contactwith activated carbon, the dynamics performance of reaction is good and the purification efficiency can be remarkably improved; and the device has the advantages of small occupied area, smooth operation of an adsorbent, small abrasion rate and very high utilization rate and has considerable economic benefits.
Description
technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a moving bed flue gas purification device. Background technique [0002] At present, the activated carbon absorption tower equipment for industrial application is generally fixed bed and moving bed technology. The moving bed process is mostly cross-flow process and counter-current process. The cross-flow process means that the flue gas passes through the activated carbon adsorption bed horizontally, and the activated carbon moves from top to bottom along the direction of gravity in the moving bed, and the flue gas and activated carbon flow in a wrong direction. However, because the flue gas passes through the activated carbon adsorption bed horizontally, the activated carbon on the inlet surface is first saturated. If the material is discharged from the bottom at the same time, the adsorption capacity of the activated carbon will not be fully utilized. In order to ...
