Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization towers and relates to a high-efficiency SDS desulfurization tower. Background Art

[0002] The SDS desulfurization process mainly involves spraying powdered fixed active calcium or sodium bicarbonate into the boiler flue gas and fully mixing it with the flue gas, converting the gaseous SO2 into granular calcium sulfate under high temperature and high humidity conditions, thereby achieving the removal of SO2 from the flue gas. The core of this process is to convert SO2 into recyclable calcium sulfate products by a dry method during the flue gas treatment process, and further reduce the impact of fossil fuel combustion emissions on the environment.

[0003] When the existing desulfurization tower is used, its function is to reduce the sulfur dioxide emission in the industrial waste gas. The desulfurization effect is achieved by preparing different desulfurizers. However, the previous desulfurization towers are empty shell towers, and the flue gas mixture does not react sufficiently in them. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a high-efficiency SDS desulfurization tower to solve the problem mentioned in the above background technology that the previous desulfurization towers are all empty shell towers and the flue gas mixture does not react sufficiently therein.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency SDS desulfurization tower, comprising a flue, a cyclone desulfurization tower, a low-pressure pulse jet bag dust collector and a chimney connected in sequence; the flue gas is tangentially connected to the interior of the cyclone desulfurization tower through the flue, and a grinder is connected to the flue through a docking pipe, and a conveying fan is also provided on the docking pipe. The grinder grinds baking soda into fine powder, which is delivered to the docking pipe from the conveying fan.

[0006] Optionally, a cyclone separator is provided in the cyclone desulfurization tower.

[0007] Optionally, a conveying pipe is provided between the cyclone desulfurization tower and the low-pressure pulse jet bag filter for connection.

[0008] Optionally, an induced draft fan for extracting flue gas is provided between the low-pressure pulse jet bag filter and the chimney.

[0009] The beneficial effects of the utility model are as follows: the high-efficiency SDS desulfurization tower of the utility model enters the flue connected to one side of the cyclone desulfurization tower through the flue gas from the docking pipe, and the baking soda powder is ground into fine powder by a grinder and delivered to the flue by a self-conveying fan, and the flue gas after the baking soda and the flue gas are mixed enters the cyclone desulfurization tower along the tangential direction. In the past, desulfurization towers were all empty shell towers. The cyclone desulfurization tower applies the principle of cyclone separators to make the flue gas mixture react more fully therein. After desulfurization, the flue gas enters the low-pressure pulse jet bag dust collector along the conveying pipe for dust removal, and then the flue gas in the low-pressure pulse jet bag dust collector is extracted by the induced draft fan, so that it is discharged from the chimney into the atmosphere, thereby achieving a more efficient desulfurization effect with a more complete reaction of the flue gas mixture.
