TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon capture, and particularly relates to a flue gas treatment carbon capture equipment. BACKGROUND

[0002] The flue gas generated by a boiler needs to be treated by multiple processes before being discharged into the atmosphere.

The carbon capture equipment intercepts carbon dioxide in the flue gas through a special filter screen, separates the flue gas and the carbon dioxide, and completes the carbon capture work.

The air passes through the filter from top to bottom and blows the carbon dioxide at the bottom of the filter. The direction of air flow is opposite to the direction in which the carbon dioxide accumulates at the bottom of the filter, and the carbon dioxide at the bottom of the filter can be blown down, which has the advantage of thorough and convenient removal of carbon dioxide.

The rolling sleeve 315 moves up and down between the two inner surrounding strips 36. Since the inner surrounding strips 36 are in a spiral winding shape, the threaded plate 38, the support member 39, the side cylinder 310, the fixed ring 311, the prism block 312, the middle rod 313, the fixed block 314, the rolling sleeve 315, the carbon scraping plate 316, and the rubber strip 317 rotate horizontally around the axial direction of the rotating rod 33 during the up-and-down movement. Since the spiral pitch of the filter groove 318 and the spiral pitch of the filter screen 28 are consistent, the rubber strip 317 rubs against the surface at the bottom of the filter screen 28. The rubber strip 317 rotates horizontally during the up-and-down movement, and the rubber strip 317 rotates spirally along the shape of the filter groove 318. The rubber strip 317 continuously rubs against the surface at the bottom of the filter screen 28, and the rubber strip 317 scrapes the carbon dioxide at the bottom of the filter screen 28.
