Abstract

The invention discloses a spiral flue gas desulphurization apparatus. The spiral flue gas desulphurization apparatus comprises a gas inlet pipe and a desulphurization tank, wherein the gas inlet pipe is located at the lower part of the desulphurization tank; an ammonia water atomization nozzle is arranged at the central part of the desulphurization tank; a flue gas discharge outlet is formed in the top of the desulphurization tank; a demisting device and spiral wind guiding vanes are arranged in the desulphurization tank; the demisting device is arranged above the ammonia water atomization nozzle; the wind guiding vanes are located above the demisting device; and the wind guiding vanes are sprayed with at least one element selected from a group consisting of praseodymium, lanthanum, cerium, nickel, zinc and titanium or a compound of the elements selected from the group. The spiral flue gas desulphurization apparatus provided by the invention has the advantages of more thorough desulphurization, recoverable byproducts, no secondary pollution, etc.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a spiral type flue gas desulfurization equipment. Background technique [0002] Coal and petroleum are the main energy sources in industrial production and daily life, but they will produce certain sulfur oxides during use, and their direct discharge into the atmosphere will cause serious pollution to the environment, such as the formation of large areas of acid rain or acid Particles settle, causing damage to the ecological environment. With the increasingly starving environment, people's awareness of environmental protection is gradually strengthened, and the research and development of flue gas desulfurization technology has become a research hotspot at home and abroad. In the flue gas desulfurization technology, the common technology is the ammonia water neutralization method, that is, after the flue gas is dedusted, it is passed into the water-containing sp...
