Turbine type pressure charging acceleration fuel gas desulfurization gas wash tower

Abstract

The invention relates to a turbine typed turbocharged accelerating flue gas desulfurization dust abatement tower, belonging to the field of gas purification technique, which includes a spray pump tower body, a slurry pump that is arranged on the tower from bottom to top and is connected with a slurry outlet at the bottom of the tower, a roots blower that is connected with a fall trachea and is arranged in a liquid storage district at the bottom in the tower, a spray pump pipe arranged over the liquid storage district, a circulating pump that is connected with and arranged in a circulating pipeline communicated with the spray pump pipe, and a demister arranged on the spray pump pipe; a flue gas inlet, a flue gas outlet and a slurry outlet are arranged on the lateral wall, on the top and at the bottom of the lower part of the spray pump tower body; a disturbance pump and a turbine typed turbocharged accelerating flue gas desulfurization dust abatement system are also included, wherein, the disturbance pump is connected with and arranged in the circulating pipeline communicated with the liquid storage district at the bottom of the tower, and the desulfurization dust abatement apparatus is arranged under the spray pump pipe in the tower and over the flue gas inlet. The invention has the advantages that sufficient connection of gas and liquid can be realized and high speed mass transfer can be carried out within the shortest time, in the smallest space and with the minimum liquid-gas ratio, thus improving high dust abatement and desulfurization efficiency with 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, a flue gas inlet, a flue gas outlet and a slurry discharge port are arranged on the tower body, and a slurry discharge pump connected to the bottom slurry discharge port of the tower is arranged from bottom to top, and a slurry discharge pump 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 t...

AI Technical Summary

Problems solved by technology

[0006] 2. The structure of the sulfur 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
