A dust-collecting electrode plate with compartmental structure for wet electrostatic dust removal

Abstract

The invention discloses a chambered structure dust-collecting pole plate for wet-type electrostatic dust collection, and belongs to the technical field of dust collection. The chambered structure dust-collecting pole plate is characterized in that the dust-collecting pole plate is a hollow pole plate, a porous material is adopted by a dust-collecting surface to guarantee the uniformity of a water film; the interior of the dust-collecting pole plate is divided into a plurality of chambers, partition plates among the chambers have through holes, the partition plates are capable of rotating along the central shaft or translating from top to the bottom; the multi-chamber structure is adopted and the water in each chamber is not full, the problems that the structure strength is poor and the water quantity permeation is non-uniform, caused by the fact that the water pressure of the hollow pole plate is gradually increased from top to the bottom, are solved. By rotating or translating the partition plates among the chambers from top to the bottom, the particles adhered on the inner surface of the porous material dust-collecting pole plate can be eliminated, the aim of recycling the water of the dust collector is realized, and the consumption of the water is reduced. An electrostatic dust collection system adopting the device disclosed by the invention is compact in structure, little in water amount, efficient and capable of realizing the large-scale application.

Description

technical field [0001] The invention relates to a dust-collecting pole plate with a compartment structure for wet electrostatic dust removal, belonging to the technical field of dust removal. Background technique [0002] A large number of gaseous pollutants and particulate matter produced by human activities are threatening the basic substance that human beings rely on for survival - clean air. Inhalable particulate matter (PM 10 ) especially fine particulate matter (PM 2.5 ) pollution has become a prominent atmospheric environmental problem, and has increasingly attracted great attention from all countries in the world. Atmospheric particulate matter (especially fine particulate matter) has been recognized as the main cause of increased human mortality. At the same time, atmospheric particulate matter is also the main cause of major air pollution problems such as reduced atmospheric visibility, acid rain, global climate change, and ozone layer destruction. Controlling ...

Problems solved by technology

The methods of applying the water film are all carried out by spraying water on the surface of the plate. In order to avoid the corrosion of the dust collection plate caused by the formation of dry areas on the surface of the plate or the incomplete water film and the low efficiency of dust removal, a large amount of water needs to be sprayed. Maintain the normal operation of the system, which will inevitably lead to an increase in water consumption
