Abstract

The invention discloses a swirl desulphurization and dust removal system. The desulphurization and dust removal system comprises a dry dust remover, a fan, a desulphurization tower, a wet electric dust remover and a chimney connected in sequence; a spray layer is arranged between a flue gas inlet and a flue gas outlet in the inner cavity of the desulphurization tower, a swirl layer is arranged between the flue gas inlet and the spray layer in the inner cavity of the desulphurization tower, a swirler is arranged on the swirl layer, and the surface of the swirler opposite to the spray layer is a conical surface. The swirl layer is arranged below the spray layer of the desulphurization tower, so that the contact area and the contact time between flue gas and slurry are improved, the mixing degree of the flue gas and the slurry is improved, and the desulphurization efficiency is thus improved; meanwhile, the dust removal effect is jointly completed by the dry dust remover and the wet electric dust remover, so that the dust removal efficiency is improved while the desulphurization efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and relates to a vortex desulfurization and dust removal system. Background technique [0002] With the rapid development of science and technology, more and more attention is paid to the impact on the environment, and the requirements for environmental emission standards are becoming more and more stringent. Coal is a relatively common and important energy source, and coal-fired power generation is one of the most important ways to utilize coal. For a long time to come, coal-fired power generation will dominate. [0003] At present, the existing flue gas desulfurization technologies include wet desulfurization and dry desulfurization and other process devices, among which wet desulfurization technology is the most widely used. Wet flue gas desulfurization is the process used by about 85% of large thermal power plants in the world today. The principle of wet flue gas desulfurizati...
