A high-efficiency desulfurization pipeline system

Abstract

The invention relates to a high-efficiency desulfurization pipeline system, which comprises a flue gas pipeline: used to guide the direction of flue gas conveying; Symmetrical filter channel; a drainage baffle: rotatably installed on the end of the flow distribution plate facing the air intake direction, the drainage baffle is provided with a rotating shaft rotatably installed at the end of the distribution plate, the rotating shaft is arranged in parallel with the flow distribution plate, and The end of the drainage baffle away from the distribution plate is always in contact with the inner wall of the flue gas pipe; a pair of filter plate groups: perpendicular to the distribution plate and slidably inserted into the filter channel, the two filter plate groups are respectively located on the distribution plate. on both sides. The invention has two sets of waste gas drainage channels used alternately, and automatically pops up and switches the waste gas drainage channels when the filter plate group is scrapped, so as to achieve the purpose of continuously screening the waste gas to remove impurities and ensure the continuous production of the front end.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a high-efficiency desulfurization pipeline system. Background technique [0002] Desulfurization generally refers to the removal of sulfur from fuel before combustion and the desulfurization process before flue gas emission. It is one of the important technical measures to prevent and control air pollution. [0003] The existing flue gas desulfurization mainly guides the flow of the flue gas through the pipeline, and adds a filter screen plate in the pipeline, first intercepts the mixed particles in the flue gas, and finally sends the flue gas into the desulfurization tower, and the desulfurization tower is sprayed for treatment. The liquid is mixed with the flue gas to achieve the purpose of flue gas desulfurization. [0004] The prior art scheme in the above has the following defects: [0005] In the actual flue gas desulfurization process, in order to improve the de...

Problems solved by technology

[0005] In the actual flue gas desulfurization process, in order to improve the desulfurization effect, it is necessary to remove the particles in the flue gas into the desulfurization tower as much as possible, reduce the chemical reaction between the particles and the treatment liquid, and facilitate the reuse of the treatment liquid. However, as The long-term use of the filter screen and the accumulation of particles on the filter screen will reduce the efficiency of flue gas passing through the filter screen and affect the efficiency of flue gas separation. Every time the machine is shut down to replace the filter screen, the flue gas desulfurization operation will not be able to be performed for a period of time.
