Ridge type demister capable of recycling flushing water, demisting system and wet desulphurization system

Abstract

The invention discloses a ridge type demister capable of recovering flushing water, a demisting system and a wet desulphurization system. The bottom of each demister blade of the ridge type demister is provided with a water collecting tank, the water collecting tanks are arranged along the length direction of the demister blades, the bottom of each demister blade is provided with a drainage tank at the lower end of the water collecting tank, and all the drainage tanks are communicated with a collecting pipe. According to the invention, the arrangement characteristic that the blades of the ridge type demister are obliquely arranged is utilized, the water collecting tank is arranged at the lower ends of the blades of the demister, and the drainage tank is arranged at the lower end of the water collecting tank and used for collecting flushing water, collecting the flushing water into the collecting pipe and recycling the flushing water finally, so that the flushing water is recycled, and a water collecting device does not need to be arranged below the demister.

Description

technical field [0001] The invention belongs to the field of flue gas environmental protection devices, and relates to a roof type mist eliminator, a mist removal system and a wet desulfurization system which can recover flushing water. Background technique [0002] The wet desulfurization process accounts for more than 92% of the flue gas desulfurization process, and the wet desulfurization process is widely used in electric power, steel and other industries. As the main device inside the wet desulfurization system, the demister can efficiently intercept the slurry droplets and prevent the flue gas from carrying the gypsum droplets into the atmosphere. The main types of mist eliminators are plate type, tube type, roof type, etc. Among them, the roof type mist eliminator is widely used in wet desulfurization system because of its high efficiency and reliability. The mist eliminator needs to be flushed regularly through the flushing nozzles arranged above the mist eliminator...

AI Technical Summary

Problems solved by technology

[0003] The existing devices for recovering the flushing water of the demister are all of the liquid receiving plate type under the demister. This method has the disadvantages of large space occupation, certain resistance, and difficult engineering implementation.
