Embodiment 1

[0027] In the first embodiment, the condenser 1 and the chimney 2 are provided with an air regulating baffle 5 on the side opposite to the chimney 2. By adjusting the opening of the air regulating baffle 5, the air intake of the hyperbolic ventilation tower 4 can be adjusted, thereby adjusting the water lift of the flue gas. The ventilation tower 4 extends to one side of the air regulating baffle 5, and the two ends of the air regulating baffle 5 are respectively connected with the ventilation tower 4 and the ground. The lower end of the chimney 2 extends under the liquid level in the reservoir 3 , the lower end of the chimney 2 is provided with an opening, and the opening runs through the inside of the chimney 2 and the reservoir 3 . The mist formed by the flue gas in the condenser 1 forms a liquid flow on the inner surface of the chimney 2 and the surface of the mist eliminator 21, flows or falls below the chimney 2, and enters the reservoir 3, and the liquid surface of the r...

Embodiment 2

[0028] In the second embodiment, a smoke distributor 6 is installed at the smoke inlet 11 of the condenser 1 , and the smoke passes through the smoke distributor 6 and then evenly distributes into the smoke condenser 1 . There is at least one set of deflectors inside the smoke distributor 6, and the deflectors are made of anti-corrosion materials such as carbon steel lining anti-corrosion scales or fiber-reinforced composite materials. The flue gas is cooled by the cold air in the flue gas condenser 1, the temperature drops, the water vapor condenses, and then enters the chimney 2. The resistance of the condenser 1 can be controlled by the flue gas flow rate. The diameter of the heat exchange tube of the condenser 1 is within Between 30-40mm, adjusting the pipe diameter can change the flue gas flow rate, and the flue gas flow rate in the pipe is 10-15 m / s. The cold air in the external environment passes through the condenser 1 after passing through the air regulating baffle 5,...

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...
