The invention relates to the purification of gaseous emissions from toxic impurities thermocatalytic technique and can be used in chemical, food, microbiological and other industries.

A device for gas purification, comprising a housing in the form of a cylindrical reaction chamber, a source of infrared rays and catalyst carrier.

A disadvantage of this device are the low efficiency associated with breakthrough no untreated axial layers of the gas flow without contact with the catalyst and low efficiency of the source of infrared radiation, scatter radiation frequencies which is great and in the required range is about 20% of what is high and what measures of considerable length for layer-by-layer processing on the catalyst of the entire gas stream and the inability to change the poisoned catalyst without changing all the other parts of the device.

The aim of the invention is to increase the efficiency of gas purification and reduce energy and material consumption of the device.

This goal is achieved by the fact that the device for gas purification, comprising a housing in the form of a cylindrical reaction chamber, a source of infrared rays and the carrier of the catalyst according to the invention, the catalyst carrier is installed in removable cassettes placed in the reaction chambers and is made in the form of a porous nozzle, the overlapping section of the reaction chambers, a source of infrared rays is made of carbon-carbon composite material and the contour of such reaction chambers.

This configuration improves the efficiency of genocide due to the greater efficiency of the emitter in a desired range of frequencies and wavelengths with increasing irradiance and reduce energy and materialoemkosti by reducing the length of the reaction chambers and power emitters, as well as the change catalyst carrier without changing the reaction chambers.

In Fig. 1 shows the proposed device; Fig. 2 section a-a in Fig. 1.

Device for cleaning gas emissions includes a housing 1, sources infraco material, for example, a catalytically active mixture, overlapping section of the housing 1 and mounted in removable cassettes 4.

The device operates as follows. Waste gases are in case 1, where exposed to the activating effects of infrared rays high-density source 3, the emission spectrum of which up to 50% coincides with the desired frequency due to selection of the composition of the carbon-carbon composition. High power density of these sources of infrared rays and the adjustable range of the radiation allows to expand the range oxidizable toxic impurities, oxidation regardless of the concentration in the discharge gas pressure and flow rate. After activation of pollutant infrared rays it oxidizes on the surface of the catalyst carrier 3, is installed in removable cassettes 4, with high efficiency due to the developed surface of the catalyst and the inability of the breakthrough separate layers of gas without contact with him. This allows to reduce the consumption of the device by reducing the length of the reaction chambers. The similarity of the shape of the reaction chambers and sources of infrared rays in the path of any projection, including in the case of execution of sources with labyrinth F. the nominal average value of the effects of activating radiation, which increases the cleaning efficiency and requires less energy, and removes restrictions from the shape and dimensions of the reaction chambers, as it allows equally rapidly affect any layer of the gas stream, regardless of the distance from the axis camera. After activation and oxidation of the contaminant, the cleaned gas out of the housing 1 into the atmosphere.

The required degree of purification is achieved in the proposed device, by adjusting the density of infrared radiation when you change the geometry of the emitters, porous catalyst carrier, or the number of consecutive in the case of the reaction chambers, for example, in Fig. 1 shows a device with two successive reaction chambers.

Thus, the proposed device allows to increase the gas purification efficiency, reduce energy and material consumption of the device.

Device for gas purification, comprising a housing with a coaxially located therein sources of infrared rays and catalyst carrier, mounted in a removable cartridge, wherein the source of infrared rays is made of carbon-carbon composite material and contour similar to the shape of the reaction to
