Double-curve natural ventilation, condensation, water lifting and white smoke elimination integral device

Abstract

The invention provides a double-curve natural ventilation, condensation, water lifting and white smoke elimination integral device which comprises a condenser, wherein the condenser comprises a smokeinlet and a smoke outlet; the smoke outlet is communicated with a chimney; a demister is arranged on the chimney; a water storage tank is arranged on the lower side of the chimney; a double-curve ventilation tower is arranged on a cooled gas flowing side of the condenser; and the smoke outlet of the chimney faces the air outlet of the ventilation tower. By adopting the device, water can be saved,the manufacturing cost is low, low energy consumption can be achieved in the operation process, and in addition, phenomena of colored smoke plume and gypsum rain can be effectively eliminated.

Description

technical field

[0001] The invention relates to a flue gas treatment device of a coal-fired power plant, in particular to a hyperbolic natural ventilation integrated device for condensing, extracting water, removing white smoke. Background technique

[0002] The current thermal power plant is equipped with a limestone-gypsum wet flue gas desulfurization system. In the limestone-gypsum flue gas desulfurization system, the high-temperature dry flue gas enters the desulfurization absorption tower, and the slurry rich in alkaline limestone is circulated and sprayed in the desulfurization tower. Absorb sulfur dioxide in flue gas. During the spraying process, a large amount of water in the slurry evaporates, making the flue gas at the outlet of the desulfurization absorption tower reach the saturation temperature of water. Usually, the temperature of the flue gas is around 50 degrees Celsius, and the moisture content in the flue gas is 10-15%. This part of the water passes through...
