Abstract
The invention relates to technological processes, in particular to the processes and devices for flue gas cleaning.The process for flue gas cleaning includes oxidation of the nitrogen and sulphur oxides by means of collision ionization in alternating electromagnetic field, ammonia neutralization of the obtained nitric and sulphurous acids, as well as subsequent separation of the gas component from the solid particles. The oxidation is carried out by letting the flue gas flow pass through a mass of cylindrical metallic particles, made of soft magnetic material, onto the surface of which there is deposited a catalytic active layer of metal oxides, the metal particles being placed in the interelectrode space in the conditions of magnetic liquefaction thereof in rotary electromagnetic field and concomitant, supplementary action of the electric field, formed by the application to the electrodes of a voltage of 50…70 V, from a constant-current source.The installation for flue gas cleaning includes, the consecutively installed and connected between them, an intake diffuser, a chamber, made in the form of a cylindrical shell of diamagnetic material, filled up with metallic particles, each end of which is closed with a net; an electromagnetic device, containing the inductance coil connected to the alternating-current source, embracing the cylindrical shell, a diffuser chamber and a cyclone. Into the cylindrical shell, supplementary connected to the negative pole of the constant-current source, it is coaxially fixed a pipe, communicating with the diffuser chamber, provided with a branch pipe for NH3 gas feeding and connected to the positive pole of the constant-current source. The metallic particles are made cylindrical, covered with a catalytic active layer and placed in the annular space between the shell and the pipe. In the diffuser chamber there are fixed the mixing members, made in the form of Z-shaped rods, being consecutively placed therein in a helical line. Onto the external surface of the inner pipe of the cyclone it is fixed a helical blade, and under the lower end of the pipe it is mounted a reflector.
