Device and method for cooperatively removing gaseous pollutants by plasma-supergravity coupling

Abstract

The invention discloses a device and a method for cooperatively removing gaseous pollutants by plasma-supergravity coupling. According to the device and the method disclosed by the invention, multiple gaseous pollutants are decomposed and oxidized by using high-energy electrons and active groups generated by low-temperature plasma discharge; in a process that the gaseous pollutants flow through a solid adsorbent reactor rotating at high speed, gas containing the pollutants are in sufficient contact with a solid adsorbent by means of a supergravity effect generated by high-speed rotation of gas and solid, to generate a gas phase-solid phase adsorption and chemical reaction to finish substance conversion and purification processes between multiple gaseous pollutants and the solid adsorbent, and thus the pollutants are converted into non-toxic and pollution-free substances. The device and the device are applicable to dry-process combined removal of multiple pollutants in flue gases and various wastes gas generated by combustion, gasification, incineration and the like in the fields of energy resources, chemical engineering, building materials, metallurgy and the like containing multiple gaseous pollutants.

Description

technical field [0001] The invention belongs to the application field of combined dry method removal of various gaseous pollutants in fossil fuel combustion, garbage incineration, various kiln flue gas and industrial waste gas, and relates to a device for plasma-supergravity coupling collaborative removal of gaseous pollutants and methods. Background technique [0002] Hazardous substances such as sulfur oxides, nitrogen oxides, organic compounds, mercury, and heavy metals emitted by fossil fuel combustion cause serious air pollution, causing serious harm to humans and the living environment. At present, air pollution control equipment mainly includes: electrostatic precipitator, bag filter, wet desulfurization and catalytic denitrification, etc., but most of the existing flue gas purification devices are single pollutant removal devices, which occupy a large area and have complicated processes. As environmental protection standards continue to improve, existing environment...

Problems solved by technology

Due to the limitation of the gravity field, there are many defects in the traditional fluidized bed, such as: surge of large particles, entrainment of small particles, cohesion, gas short circuit caused by the existence of large bubbles, resulting in uneven distribution of gas and solid, which greatly reduces the transmission rate in the system. mass, heat transfer, and chemical reaction rates, etc.
