Abstract

The invention discloses an efficient condensation absorption tower. The efficient condensation absorption tower is characterized in that the efficient condensation absorption tower comprises a tower body; a slurry tank is arranged at the inner side of the lower part of the tower body; the left lower part of the tower body is connected with a flue gas inlet pipe; the joint of the flue gas inlet pipe and the tower body is higher than the liquid level of the slurry tank; the flue gas inlet pipe is obliquely arranged; one end, connected with the tower body, of the flue gas inlet pipe is lower thanthe other end; the upper part of the tower body is connected with a flue gas outlet pipe; and a condensation tray, a spraying area and four layers of demisters are sequentially arranged above the slurry tank in the tower body from bottom to top. According to the invention, exhaust gas temperature can be reduced, part of liquid water is recovered from saturated wet flue gas, and evaporation of water in the absorption tower is reduced, so water replenishment of a wet desulphurization system is reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to an efficient condensation absorption tower. Background technique [0002] The flue gas produced by coal-fired boilers generally needs to be denitrified, dust removed, and desulfurized to remove pollutants in the flue gas before being discharged into the atmosphere. Limestone gypsum desulfurization process is generally used for desulfurization, and a spray empty tower is set up, and a slurry pool area, a tray area, a spray area and a demister area are set in the tower. [0003] The flue gas temperature at the inlet of wet desulfurization is generally greater than 120°C. After the flue gas is washed by the slurry sprayed in the spray area, the flue gas temperature drops to about 50°C, and it is in a state of saturated wet flue gas. Due to the obvious temperature drop, a large amount of water carried by the slurry evaporates into the flue gas. In order to maintain the wa...
