Turbulent ball type turbocharging compound desulfurization dust removal tower

Abstract

The invention relates to a turbulent ball type turbocharging compound desulfurization dust removal tower, which belongs to the technical field of gas purification and comprises a spraying tower body, a gas inlet, a smoke outlet, a slurry discharger, a slurry discharge pump, a Roots blower, multilayer spraying pipes, an annular separation plate, a circulation pump, a demister, a disturbance pump and a plurality of turbulent ball type turbocharging acceleration smoke gas desulfurization dust removal devices, wherein the turbulent ball type turbocharging acceleration smoke gas desulfurization dust removal devices are arranged in the tower and respectively comprise a casing, a pipeline, upper and lower porous end plates, a turbulent ball and a plurality of blades, the pipeline is fixedly arranged in the center of the casing, the upper and lower porous end plates are respectively arranged at the upper end and the middle part of the casing, the turbulent ball is filled in the space between the upper and lower porous end plates, the blades are arranged between the porous end plates and the pipeline, the upper end of each blade is connected with the inner wall of the casing, the lower end of each blade is connected with the outer wall of the pipeline, and the lower end of the casing is connected with a smoke shielding cover. The turbulent ball type turbocharging compound desulfurization dust removal tower has the advantages that the full gas and liquid contact can be realized under the conditions of the shortest time, the smallest space and the lowest liquid-gas ratio, the high-speed mass transfer is carried out, and the high dust removal and desulfurization efficiency can be improved at the minimum energy consumption.

Description

technical field [0001] The invention belongs to the technical field of gas purification, in particular to the structural design of boiler flue gas desulfurization and dust removal equipment. Background technique [0002] At present, the wet technology in the boiler flue gas desulfurization and dedusting tower has a spray tower with a cyclone. The tower includes: a tower body, the tower body is provided with a flue gas inlet, a flue gas outlet and a slurry discharge port, the tower is provided with a slurry discharge pump connected to the bottom of the tower from bottom to top, and is arranged on the tower A Roots blower connected to the aeration pipe in the liquid storage area at the inner bottom, a circulation pump connected to the circulation pipe connected to the liquid storage area and the spray pipe on it, and a mist eliminator arranged on the spray pipe ; It also includes the cyclone arranged under the spray pipe in the tower and above the flue gas inlet, which is mai...

AI Technical Summary

Problems solved by technology

[0006] 2. The structure of the cyclone is complex, easy to scale, and the desulfurization efficiency decreases with the increase of the tower diameter

[0007] 3. For tangential air intake, the center is easy to form a low-efficiency zone
