The invention relates to equipment for the heat treatment of gas emissions and can be used in industrial ecology.

Known reactor thermal oxidation gas emissions, comprising a housing with inlet and outlet nozzles and placed it perpendicular to the axis of the heated walls with holes, installed with a gap (SU authorship 1649213, CL F 23 G 7/06, 1991).

The disadvantage of this reactor is the low efficiency gazooks the

This result is achieved by the fact that the reactor thermal oxidation gas emissions, comprising a housing with inlet and outlet nozzles and placed in it the heated walls with holes, according to the invention, partitions are made corrugated, the openings are placed on one side of each partition on the ridges, and the partitions are placed so that their crests are non-parallel to the axis of the housing and the crests of the adjacent partitions, and combs without holes placed in the holes in the flanges of adjacent partitions with the formation of intersecting channels.

This allows to increase the efficiency of gas purification due to the intensification of the mixing of waste gases and the surface of contact of the gases with the heated surfaces.

In a preferred embodiment, the profile of the holes does not match the profile of the ridges.

This further improves the efficiency of gas purification due to additional intensify mixing gas emissions and development of the contact surface.

In Fig. 1 shows a diagram of the proposed reactor of Fig. 2 shows the front view of the partition of Fig. 3 - section a-a of Fig. 2; Fig. 4 and 5 presents options soedinenii 2 and output 3 nozzles and placed in it the heated walls 4. Each partition wall 4 is made of corrugated and has ridges 5 and openings 6. Partitions 4 are placed so that their crests 5 non-parallel to the axis of the housing 1 and the ridges 5 of the adjacent partition walls 4. Holes 6 made in the ridges 5 on one side of each of the partition walls 4. Combs 5 without holes placed in the holes 6 of the adjacent walls 4 with the formation of intersecting channels. In a preferred embodiment, the profile of the holes 6 and the ridges 5 are not the same, that is, between the edges of the holes 6 and the surface of the ridges 5 are structurally defined gaps 7 of arbitrary shape.

The reactor gas emissions are served in the casing 1 through the pipe 2. The gas flow is divided into separate flows through the channels formed by the partition walls 4, interacting with their hot surfaces and mixing in the zone of intersection of the channels between adjacent partition walls 4. If this does not match the profile of the holes 6 therein, the ridges 5 of the gas streams are mixed, flowing through the gaps 7 on the opposite surfaces of the partition walls 4. Contact gas streams with partitions 4 leads to the oxidation of toxic contaminants to harmless substances. The intensive mixing of the exceptions is the efficiency of the gas cleaning system. At the same time describes the location of the partitions 4 provides for the development of surface contact and the absence of dead zones while reducing the hydraulic resistance of the gas stream. The thus treated stream that does not contain toxic impurities, is removed from the housing 1 through the pipe 3 and is discharged into the atmosphere.

Thus, the proposed reactor improves the efficiency of gas purification.

FIELD: by-product-coking industry; methods of purification of waste gases of the fuel incineration furnaces.

SUBSTANCE: the invention is pertaining to the field of by-product-coking industry, in particular, to the method of purification of waste gases of the fuel incineration furnaces. The method is defined by the fact, that using a part of the purified waste gases they form a backflow used for creation of a counterflow to the main stream of the waste gases and formation of a total flow fed to the purification. At that the speed of the backflow is kept within the limits of 0.1-1.0 m\s, and temperature of the total flow is kept by 2-30°C below the temperature of the main stream of the waste gases. The invention allows to raise efficiency of the smoke purification due to regulation of parameters of the hydraulic mode of the offered method.

EFFECT: the invention ensures a raise of efficiency of the smoke purification.
