Problems solved by technology
[0003] Among various air pollutants, NOx, mercury and compounds are the most difficult to control. At present, the technology for controlling NOx emissions in thermal power plants is mainly based on selective catalytic reduction (SCR) denitrification technology. This method has high denitrification efficiency, but because the catalyst is easy to deactivate , Regeneration is difficult, expensive and other shortcomings are limited

The invention provides a vertical type pneumatic rotary self-excitation waste gas purification apparatus. A waste gas purification apparatus body is tangentially connected with a flue gas inlet pipeline, a pneumatic rotary self-excitation rotor is arranged inside the waste gas purification apparatus body, a demister is arranged at the upper part of an inner barrel, and the top part of the inner barrel is connected with a purified gas outlet pipeline. According to the vertical type pneumatic rotary self-excitation waste gas purification apparatus adopting the technical scheme, the force of flue gas from a tangential inlet pushes the rotor to rotate, a rotary self-excitation blade stirs fluid to generate self-excitation foams, and liquid flow impacts the fitting surface of a cobblestone when reaching a foam self-excitation zone, so that the self-excitation effect is improved, and harmful gas in flue gas can be completely absorbed into a liquid phase and is oxidized under the irradiation of ultraviolet light for achieving the purpose of removing harmful substances in flue gas. The waste gas purification apparatus can treat different kinds of waste gases (such as flue gas containing SO2, NOx, Hg and other harmful substances), and has the characteristics of simple structure, low energy consumption, convenience for operation, wide adaptability, good removing effect and the like.
Description
technical field [0001] The invention belongs to the technical field of air pollution control, and relates to an industrial waste gas treatment device, especially for NO, SO 2 And other harmful gas oxidation treatment, specifically a vertical pneumatic rotary self-excited waste gas purification device. Background technique [0002] Since my country is a country rich in coal, poor in oil and little in gas, coal plays a dominant role in my country's primary energy structure, and for a relatively long period of time in the future, my country's electric power industry will still use coal as the main fuel. my country's coal has the characteristics of high sulfur, high ash, and difficult to wash. The development and utilization of coal has become the main source of my country's air pollutant emissions. Therefore, our energy development is facing serious environmental challenges. At present, the main air pollutants carried in the flue gas of coal-fired boilers are dust, SO 2 , NOx...
