Description
Technical Field
The invention relates to the field of flue gas whitening, in particular to a cooling and dehumidifying flue gas whitening system.
Background
The wet flue gas desulfurization process is widely applied to the environmental protection treatment of the flue gas of a power plant. The sulfur oxides discharged into the atmosphere are reduced after the high-temperature flue gas generated by burning the coal is subjected to desulfurization treatment.
Since the smoke generated by reducing sulfur oxides is discharged into the atmosphere and "white smoke" is easily generated, a great deal of research on solving the "white smoke" in the prior art, such as research on reducing the moisture content of saturated wet smoke by water spraying and synergistically treating the problem of pollution of brother, and further research on the technology of rotary spray drying smoke desulfurization.
The high-temperature flue gas is desulfurized by adopting a desulfurizing tower, and sulfur oxides in the flue gas treated by the desulfurizing tower are obviously reduced.
However, the high-temperature flue gas after the desulfurization treatment is discharged into the atmosphere, and the flue gas has a high temperature and a high humidity, and is very likely to be discharged into the atmosphere through a chimney to cause a phenomenon such as "white smoke" or "gypsum rain".
The reason for this is that the high-temperature flue gas has high humidity and high temperature, and the high-temperature flue gas contacts the atmosphere to generate the white smoke or the gypsum rain to form haze which affects the environment.
In order to solve the problem that the flue gas discharged by the desulfurizing tower is treated in the prior art of poor generation of 'white smoke' in the desulfurizing process. For example, the Chinese patent application number is: CN201920073570.1, disclosing "a smoke dehumidifying and whitening device", reported in the patent: the flue gas dehumidification and whitening device comprises a flue, wherein the flue is sequentially divided into a primary condensation section, a secondary condensation section and a heating section along the flow direction of flue gas, a first guide groove which is obliquely arranged is arranged in the primary condensation section, a shell is sleeved outside the flue above the first guide groove, and the shell is matched with the outer wall of the flue to form a cooling water channel; corrugated plates are uniformly arranged in the secondary condensation section, the corrugated plates are arranged in a staggered manner, and adjacent corrugated plates are respectively fixed with the upper wall and the lower wall of the flue; a pipeline for sequentially connecting the hollows of the corrugated plates is arranged outside the flue, and the cooling water channel and the corrugated plates are hollow and matched to form a circulating cooling water system; an inclined second diversion trench is fixed at the bottom end of the corrugated plate; the heating section is internally provided with a heating mechanism.
Through the technical scheme reported in the patent literature, the problem of eliminating white smoke plume at the outlet of the chimney is solved.
However, the technical solutions reported in the above patents have the following disadvantages:
1. the high-temperature flue gas has poor dehumidification effect, and although white smoke plume and white smoke of the dehumidified flue gas are reduced, a large amount of white smoke can still be formed in the discharged flue gas;
2. the heat recovery utilization rate is low, so that the treatment cost of the flue gas is too high in the flue gas treatment process, and the energy can not be effectively saved.
