Flue gas deep cooler for achieving gas-liquid-solid condensation and absorbing and restraining low-temperature corrosion

Abstract

The invention discloses a flue gas deep cooler for achieving gas-liquid-solid condensation and absorbing and restraining low-temperature corrosion. The flue gas deep cooler comprises a left pipe plate, a middle pipe plate, a right pipe plate, an anti-abrasion polished pipe, a bent type heat exchange base pipe, a plurality of drainage gap slope type anti-impact wear-resisting H-shaped fins and a plurality of H-shaped fins, wherein the anti-abrasion polished pipe is located on the flue gas impact side and installed on the left pipe plate, the middle pipe plate and the right pipe plate, the benttype heat exchange base pipe is located above the anti-abrasion polished pipe, internally contains circulation cooling water, and is installed on the left pipe plate, the middle pipe plate and the right pipe plate for resisting flue gas impact, the drainage gap slope type anti-impact wear-resisting H-shaped fins are installed on the bent type heat exchange base pipe, and the H-shaped fins are located above the drainage gap slope type anti-impact wear-resisting H-shaped fins and installed on the bent type heat exchange base pipe. The flue gas deep cooler can be widely applied to power station boiler and industrial boiler flue gas treating systems.

Description

technical field [0001] The invention relates to a flue gas deep cooler capable of solidifying gas and liquid and absorbing and inhibiting low-temperature corrosion, which can be widely used in power plant boilers and industrial boiler flue gas treatment systems. Background technique [0002] Flue gas from thermal power plants pollutes the environment seriously. It is a pollutant that requires strict control around the world, and it is also a technical problem in environmental protection in the production process of thermal power plants. The flue gas at the outlet of the desulfurization tower is usually saturated wet flue gas, which contains a large amount of water vapor, and the water vapor contains more dissolved salts, SO3, gel dust, and fine dust, which are the main components of smog. If the flue gas is discharged directly into the chimney and enters the ambient air with a lower temperature, since the saturated humidity of the ambient air is relatively low, the water vap...

AI Technical Summary

Problems solved by technology

If the flue gas is discharged directly into the chimney and enters the ambient air with a lower temperature, since the saturated humidity of the ambient air is relatively low, the water vapor in the flue gas will condense to form a wet plume during the temperature reduction of the flue gas, causing damage to the atmosphere.
