Abstract

The invention belongs to the field of steelmaking equipment, and in particular relates to a flue gas treatment device of an iron ore sintering platform. The flue gas treatment device is characterized in that an air inlet of a fan is connected with the sintering platform through a pipeline; an air outlet of the fan is connected with a dust removing device through a pipeline; the dust removing device is connected with an organic solvent absorption tank through a gas transmission pipeline A; furthermore, the tail end of the gas transmission pipeline A is inserted below the liquid level in the organic solvent absorption tank; the organic solvent absorption tank is communicated with an alkali solution absorption tank through a gas transmission pipeline B; furthermore, the tail end of the gas transmission pipeline B is inserted below the liquid level in the alkali solution absorption tank; an exhaust pipeline, the tail end of which is higher than the liquid level, is arranged at the upper end of the alkali solution absorption tank; furthermore, a waste liquid discharging pipe is arranged at the lower part of the alkali solution absorption tank; a control valve is arranged on the waste liquid discharging pipe; and an exhaust device is arranged on the exhaust pipeline. The flue gas treatment device disclosed by the invention is simple in structure and low in cost and treatment cost.

Description

technical field [0001] The invention belongs to the field of steelmaking equipment, in particular to a flue gas treatment device for an iron ore sintering platform. Background technique [0002] During the sintering process of iron ore, a large amount of flue gas will be produced, and the harmful substances in the flue gas are mainly sulfur dioxide, sulfur trioxide, dioxin and dust. Sulfur dioxide and sulfur trioxide are the main sources of acid rain. The concentration of sulfur dioxide in the atmosphere above 0.5ppm has a potential impact on the human body. When the concentration of sulfur dioxide is 1-3ppm, most people begin to feel irritation. When it is 400-500ppm, people will appear ulcers and pulmonary edema. until death by suffocation; sulfur trioxide has a strong stimulating and corrosive effect on skin, mucous membranes and other tissues, and can cause conjunctivitis, edema, respiratory irritation symptoms, and severe cases of dyspnea and pulmonary edema; The most ...
