A desulfurization and dust removal equipment is used for removing sulfur dioxide and soot from coal-fired flue gas, the desulfurization and dust removal equipment comprises a horizontally arranged cylindrical shell; the inner lower side of the shell accommodates ammonia water, A drive shaft is arranged in the axial direction of the housing, a plurality of filter turntables are arranged side by side on the drive shaft, a spiral groove is arranged along the rotating surface of the filter turntable, and at least one side of the spiral groove is provided with a filter screen cloth; at least one side surface of the helical groove is provided with a plurality of connecting reinforcements extending radially outward from the driving shaft. The desulfurization and dust removal of the present invention greatly increases the contact area between the flue gas and ammonia water by using a filter turntable with a spiral groove structure, improves the dust removal efficiency, and can further avoid regular shutdowns without additional cleaning devices to clean the fouling, so that the The desulfurization and dust removal of the invention can run continuously and efficiently, save the consumption of ammonia water, and reduce the cost.
Description
technical field [0001] The invention relates to a deep purification technology for coal-fired flue gas emissions in industries such as electric power, chemical industry, metallurgy, and manufacturing, and in particular to a desulfurization and dust removal equipment for removing sulfur and smoke in coal-fired flue gas. Background technique [0002] Coal-fired flue gas emissions from electric power, chemical industry, metallurgy, and manufacturing industries have a great impact on air pollution. Among them, harmful substances such as soot, sulfur dioxide, and nitrogen oxides contained in coal-burning flue gas are one of the root causes of air pollution, acid rain, and greenhouse effect. At present, my country has carried out large-scale flue gas desulfurization projects, but the flue gas emissions still cannot meet the current standard requirements, and further treatment is still needed. [0003] Existing desulfurization technology often adopts a mechanical demister on the t...
