Abstract

The invention discloses a desulfurizing tower which comprises a concrete tower, an anchor PP (polypropylene) plate, an alloy plate and a plug welding material, wherein a flue gas inlet is formed in the concrete tower; the flue gas inlet communicates with the inner cavity of the concrete tower; the PP plate is arranged at a fixing part; the fixing part is buried in the inner wall of the concrete tower; the anchor PP plate covers the inner wall of the concrete tower; the alloy plate extends into the concrete tower from the inner wall of the flue gas inlet and is in lap joint with the anchor PP plate; a first plug welding hole is formed in an area in lap joint with the anchor PP plate, of the alloy plate; the first sealing PP plate, the alloy plate and the anchor PP plate are overlapped in sequence; a second plug welding hole communicating with the first plug welding is formed in the first sealing PP plate; and the plug welding material is filled into the first plug welding hole and the second plug welding to fixedly connect the anchor PP plate, the alloy plate and the first sealing PP plate. By adopting the scheme, the problem that an alloy plate and an anchor PP plate in a conventional desulfurizing tower cannot be connected in a sealed manner can be solved.

Description

technical field [0001] The invention relates to the technical field of desulfurization tower anticorrosion, in particular to a desulfurization tower. Background technique [0002] The flue gas discharged from boilers in thermal power plants contains a large amount of pollutants such as sulfur dioxide, nitrogen oxides, and dust. Therefore, limestone-gypsum wet desulfurization technology is often used in thermal power plants to reduce sulfur dioxide, nitrogen oxides, and dust in flue gas. The flue gas is passed into the desulfurization tower, and the spray device in the desulfurization tower sprays limestone slurry and mixes with the flue gas to achieve the purpose of desulfurization and dust removal. [0003] Conventional desulfurization towers use a concrete tower body. In order to prevent flue gas and limestone slurry from corroding the concrete tower body, glass scales are often pasted on the inner surface of the concrete tower body to prevent corrosion of the concrete tow...
