Efficient desulfurization and dust removal integrated device and dust removing method thereof

Abstract

The invention relates to an efficient desulfurization and dust removal integrated device and a dust removing method of the efficient desulfurization and dust removal integrated device. The efficient desulfurization and dust removal integrated device comprises an atomizing chamber, wherein the atomizing chamber is connected with a spray dust settling chamber, a distribution chamber and a reaction chamber which are connected in sequence are arranged below the spray dust settling chamber, a gas collection chamber and a demister are arranged above the spray dust settling chamber in sequence, a nozzle for an oxidizing agent is arranged at a connecting opening of the spray dust settling chamber and the distribution chamber, and a nozzle for slurry for spray desulfuration, denitration and dust removal for the first time is installed in the spray dust settling chamber. The integrated device disclosed by the invention has the advantages of simple structure and convenience in use. According to the dust removing method implemented by the device, water spray dust removal, water bath dust removal, spray desulfuration and denitration, bubbling desulfuration and denitration, oxidizing agent oxidation and foam dust removal are organically combined, two-time desulfuration, denitration and dust removal are performed, the blocking problem of an aerator pipe is solved, the insertion depth of an aerator pipe is reduced, the resistance and the running cost are reduced, and the desulfuration, denitration and dust removal efficiencies are improved.

Description

(1) Technical field [0001] The invention relates to problems related to flue gas desulfurization, denitrification, mercury removal and dust removal, and belongs to the technical field of desulfurization, denitrification, mercury removal and dust removal, and in particular relates to a high-efficiency desulfurization and dust removal comprehensive device and a dust removal method thereof. (2) Background technology [0002] At present, the domestic air pollution is very serious. The Ministry of Environmental Protection of the People's Republic of China has made stricter regulations on the emission limits of the three main pollutants, smoke, sulfur dioxide and nitrogen oxides. However, the improvement of emission standards requires a lot of construction funds and operating costs. If the current pollution control method of "treating the head and treating the foot" is adopted, the enterprise will be overwhelmed. In order to meet the requirements of environmental protection, m...

Problems solved by technology

However, the improvement of emission standards requires a lot of construction funds and operating costs. If the current pollution control method of "treating the head and treating the foot" is adopted, the enterprise will be overwhelmed

In order to meet the requirements of environmental protection, most enterprises generally adopt dust removal and only consider the transformation of dust removal equipment, and desulfurization only consider the transformation of desulfurization equipment, without comprehensive consideration, resulting in waste of investment and increased operating costs.
