Detailed Description
The present invention will be described in detail with reference to fig. 1 to 3, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides an internal circulation desulfurization tower slurry anti-sedimentation arrangement process through improvement, the inlet of a slurry circulating pump is arranged tangentially after being equally divided by 360 degrees in a tower kettle slurry area, and the slurry in the inner layer and the outer layer of the tower kettle slurry area rotates along the tower wall by utilizing the suction force of the inlet of the slurry circulating pump in tangential distribution. Three sets of oxidation aeration pipes are uniformly distributed at 120 degrees in the slurry area of the tower kettle (the pipe orifice is 650mm away from the bottom plate of the tower, the outlet direction is downwards distributed at 120 degrees along the circumferential tangential direction), and one oxidation aeration pipe is distributed at the center of the slurry area of the tower kettle (the pipe orifice is 650mm away from the bottom plate of the tower, and the outlet direction is vertically downwards). The inner layer slurry in the slurry area of the tower kettle is rotated by utilizing tangential thrust generated during aeration of the oxidation aeration pipe, and the oxidation aeration pipe is arranged at the center of the slurry area, so that the phenomenon that particles in the slurry are accumulated at the center of the tower bottom due to rotation of the slurry in the tower is avoided. Therefore, the invention effectively avoids the blockage of the tower bottom and the pipeline caused by the slurry sedimentation in the slurry area of the internal circulation desulfurization tower by adjusting the positions of the inlet of the slurry circulating pump and the oxidation aeration pipe. The invention cancels three stirrers in the slurry area of the internal circulation tower, reduces the primary investment cost and the operation and maintenance cost, and achieves the purposes of environmental protection, energy conservation and emission reduction.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
