Novel flue gas desulfurization method

Abstract

The invention discloses a novel flue gas desulfurization method, and belongs to the technical field of flue gas treatment. The novel flue gas desulfurization method comprises a desulfurization device,wherein the desulfurization device comprises a large annular pipe and a small annular pipe, the outer side wall of one end of the large annular pipe is communicated with a gas inlet pipe, the inner side wall of the other end of the large annular pipe is communicated with a gas guide pipe, the end, which is away from the large annular pipe, of the gas guide pipe is communicated with the small annular pipe, and the front outer wall of the end, which is away from the gas guide pipe, of the small annular pipe is communicated with a gas outlet pipe. A desulfurization ball mechanism is arranged incombination with dry desulfurization and wet desulfurization, desulfurization can be effectively and quickly carried out on the flue gas, and the desulfurization efficiency is high. With the arrangement of the large annular pipe and the small annular pipe, the flue gas flowing path can be prolonged, and the desulfurization effect can be improved. In addition, the structure is simple, and the occupied area is small. The drying ball mechanism is further arranged, the flue gas can be dried, the flue gas can be heated, and the flue gas is not subjected to significant cooling during the purification process.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, and more specifically relates to a novel flue gas desulfurization method. Background technique [0002] The sulfur dioxide contained in the flue gas will cause very serious pollution to the atmospheric environment, seriously destroy the ecological balance, and cause great harm to the health of animals, plants and humans. Acid rain will also occur to a large extent, which will damage the building Corrosion and destruction of objects seriously affect the ecological environment and living environment. Therefore, in order to effectively reduce the hazards of sulfur dioxide, relevant departments continue to research and develop related treatment technologies. At the present stage, the technical means to control sulfur dioxide pollution is mainly flue gas desulfurization, and in industry, it is mainly wet desulfurization technology. Among them, the wet desulfurization technology has the ad...

Problems solved by technology

[0003] In the prior art, there are various desulfurization methods, but there are generally some disadvantages. For example, wet desulfurization has the advantages of fast desulfurization reaction speed, simple equipment, and high desulfurization efficiency. Pollution and other issues, dry desulfurization has the advantages of no sewag
