The invention provides a desulfurizing and dedusting device and a desulfurizing and dedusting method. The invention provides a desulfurizing and dedusting device firstly. The desulfurizing and dedusting device comprises a desulfurizing and dedusting module, a waste liquid processing module and a dehydrating module; the desulfurizing and dedusting module mainly comprises a liquid alkaline tank (11), an absorption tower (3) and a circulation tank (9); the waste liquid processing module mainly comprises a medicating tank (15), a sedimentator (14), an oxidizing tank (17), an external water drainage tank (21), a plant area sewage treatment plant (23) and a filtrate storage tank (19); the dehydrating module mainly comprises a plate-frame-type press filter (25). The invention provides a desulfurizing and dedusting method according to the device. The desulfurizing and dedusting device and method which are provided by the invention have the beneficial effects of low investment, high desulfurizing and dedusting efficiency and short construction cycle and is adaptive to the situation of China.
Description
technical field [0001] The present invention relates to the technical field of environmental protection, in particular to a pollution control equipment and method, in particular to a desulfurization and dust removal equipment and method. Background technique [0002] The National Environmental Protection "Twelfth Five-Year Plan" points out that industrial kilns in industries such as petroleum and petrochemical, non-ferrous metals, and building materials should undergo desulfurization transformation. The total amount of sulfur dioxide emissions in the main indicators of environmental protection during the "Twelfth Five-Year Plan" is required to drop to 20.864 million tons by 2015, a drop of 8% compared to 2010. At present, my country's coal-fired power plant boiler equipment desulfurization project is nearing completion, so the reduction of flue gas SO2 emissions from catalytic cracking units in oil refineries is receiving unprecedented attention. [0003] At present, wet me...
