Description

Flue gas desulfurization and purification equipment

Technical Field

The utility model belongs to the environmental protection field is administered to the industry flue gas degree of depth, specifically speaking is a flue gas desulfurization clarification plant.

Background

Environmental problems such as acid rain, reduced atmospheric visibility, and fog weather, attention of the public has been focused mainly on dust, sulfur dioxide (SO2), and nitrogen oxides (NOx), and there is little discussion about the effects of condensable particulate matter, sulfur trioxide (SO 3). In fact, condensable particulates, SO3, present as a pollutant in the flue gas of coal-fired boilers in large quantities, are more than ten times more hazardous than SO 2. Excessive SO3 in the flue gas directly causes the phenomenon of 'colored smoke plume', and is also a main reason for forming acid rain. In addition, the condensable particles and the sulfuric acid aerosol formed by SO3 are precursors of PM2.5, and the haze phenomenon is aggravated. The PM2.5 has larger specific surface area and is easy to enrich various heavy metal pollutants. Among them, mercury (Hg), one of the toxic heavy metals, is toxic and arranged at the head, and can be stored for a long time after entering the human body in the form of aerosol, vapor or dust through respiration, resulting in slow development of the body, causing various cancers and heart diseases, and causing great harm to the ecological environment and human health.

The traditional wet desulphurization has high SO2 removal efficiency, but a large amount of gaseous organic or inorganic substances with extremely small volume in the flue gas after wet desulphurization are diluted in a tower, cooled for a few seconds and condensed into liquid or solid, condensable particles are generated through condensation, collision and combination, and part of SO3 is not absorbed in the desulphurization and dehumidification tower in time, SO that submicron sulfuric acid mist aerosol particles which are difficult to capture are rapidly generated. When the dust concentration in the flue gas is low, the dust is not enough to adsorb condensable particles and sulfuric acid mist, so that the condensable particles and the sulfuric acid mist escape. And the pollutants are further converted into PM2.5, a carrier or a reaction bed is provided for heavy metals such as mercury and the like, and the pollutants are discharged into the atmosphere along with flue gas, so that the haze phenomenon is aggravated, and the health of a human body is influenced. The key problem to be solved urgently is to control the emission of condensable particles and SO3 in the coal-fired power plant and further control the emission of PM2.5 and heavy metal Hg pollution. Wherein, above-mentioned problem is solved by chinese utility model (CN 208032289U), in this patent, is equipped with the cooling water circulating pump to can reach the purpose of water economy resource with the water cyclic utilization that reacts in the desulfurizing tower, but when using, the inside partial granule of packing layer can be followed rivers and flowed into in the water catch bowl of desulfurizing tower lower part and by the suction cooling water circulating pump under the cooling water circulating pump effect, thereby leads to the cooling water circulating pump to block up very easily, causes the damage.
