Изобретение относитс к устройствам дл сжигани сбросных газов и может быть использовано в тех отрасл х промышленности , в результате де тельности которых образуютс газообразные отходы, подлежащие обезвреживанию.The invention relates to devices for the incineration of waste gases and can be used in those sectors of industry, as a result of which gaseous wastes are generated to be disposed of.

Известно устройство дл сжигани газов , содержащее воздухоподвод щий корпус и установленную в нем цилиндрическую камеру сгорани с перфорированной конической головкой. В корпусе у вершины и основани конической головки установлены диафрагмы 1.A device for combustion of gases is known, comprising an air inlet housing and a cylindrical combustion chamber with a perforated conical head mounted therein. Diaphragm 1 is mounted in the housing at the top and base of the conical head.

Недостатком известного устройства вл етс то, что камера сгорани выполнена открытой, не обеспечивает необходимую температуру сгорани газа, из-за чего снижаетс полнота сгорани топлива и загр зненного воздуха.A disadvantage of the known device is that the combustion chamber is made open, does not provide the necessary temperature for the combustion of gas, which reduces the completeness of the combustion of fuel and polluted air.

15 a device for burning waste gases, containing a cylindrical vortex furnace with an outlet confused nozzle, protrusions on the inner surface located along a helical line, a conical 20 head with openings for supplying waste gases and an additional fuel burner enclosed in a heat-insulating casing with the formation of a cavity, connected through the holes of the conical head with the furnace space, the burner is made in the form of an annular manifold with gas nozzles and is installed at the base of the conical head, filled with an axial channel with a flap, with the burner nozzles directed parallel to the surface of the conical head. The drawing shows a device for burning waste gases. The device for burning the waste gases contains a cylindrical vortex furnace 1, equipped with an outlet confusing nozzle 2. The internal surface of the furnace is made with protrusions 3 located along a helix. Inside the furnace 1, an annular diffusion burner 4 is installed at the inlet, adjacent to the conical head 5 with a gap, forming a combustion chamber 6. The burner 4 has gas supply nozzles 7 directed parallel to the surface of the conical head 5. Side holes 8 are made in the conical head, and an axial gas supply channel 9 equipped with a control flap 10. The furnace is enclosed with a gap in the heat-insulated casing 11, equipped with a scroll 12, for supplying waste gases. The gap between the walls of the furnace and the casing forms a cavity 13 bounded by a gate 14 for regulating the flow of waste gases. The device works as follows. The waste gas or polluted air enters the cavity 13 through the cochlea 12, where it swirls and divides into two streams. Natural gas is fed through the burner 4 by nozzles 7 of the gas supply, directed parallel to the surface of the conical head. The gas exits at an angle, forming a ring of fire in the combustion chamber 6 of the furnace 1. The first stream of waste gases enters the cavity 13, where it is preheated from the walls of the furnace 1 and out through the annular gap formed by the valve 14 and the outer walls of the outlet nozzle 2. Another waste stream gases enter the combustion chamber 6 from the side openings 8 and the axial channel 9 of the conical head 5. The exhaust air from the side openings 8 is directed by separate jets into the combustion chamber 6, ejected by the jets of fuel coming out of the nozzle 7 of the burner 4, burns to form a ring fiery torch. An annular fire torch is located along the axis of the combustion chamber and thereby reduces the overheating of the walls. The contaminated air entering the combustion chamber through the gap formed by the inlet channel 9 and the flap 10, meets with a fiery torch, burns, breaks down into separate jets and is directed to the walls. On the walls of the combustion chamber, non-burning particles of combustible waste gas and fuel components break up by the projections 3, recycle and burn to form a hot mixture. Thus, the supply of waste air through the inlet 9, equipped with a flap 10, forming an adjustable gap, provides fiery air treatment, which gives an increase in performance, and its regulation increases the range of performance control. The high-temperature flow of the hot mixture through the confused connection 2, displacing with the preheated part of the waste gas of the first flow, contributes to the combustion of harmful impurities in it. Maintaining the required temperature in the vortex furnace is controlled by regulating the supply of fuel to the burner 4, the supply of waste gases through the axial channel 9 by the damper 10. and the damper 14. The design of the device for exhaust gases equipped with an annular burner with gas nozzles directed parallel to the surface of the conical head made with a channel equipped with a gate for controlling the flow of waste gases increases the efficiency of filling the furnace space and increases the range of production control performance The use of the proposed device reduces the pollution of the surrounding air environment by effectively burning harmful impurities — vapors of solvents; it saves fuel by burning particles of waste gases in the combustion chamber. The invention The device for burning waste gases, containing a cylindrical vortex furnace with an outlet flue pipe, protrusions on the inner surface, arranged in a helical line, a conical head with openings for supplying waste gases and a burner for additional fuel enclosed in a heat-insulating casing with the formation of a cavity communicating through the holes of the conical head with the furnace space, characterized in that, in order to increase the efficiency of operation, the burner is designed as an annular collar A lecturer with gas supply nozzles and installed at the base of the conical head, made with an axial channel with a flap, while the burner nozzles are directed parallel to the surface of the conical head.
