Combustion exhaust gas filtering device

Abstract

The invention discloses a combustion exhaust gas filtering device. A spraying device is fixed in a shell, and comprises a circulating water pump, a water guide pipe, a water pumping pipe, a water feeding pipe and nozzles; the input end of the circulating water pump is connected with the interior of the shell through the water pumping pipe; the water pumping pipe is fixed with the shell; the outputend of the circulating water pump is connected with the water feeding pipe through the water guide pipe; the water feeding pipe is fixed with the shell; a plurality of nozzles are fixed at the bottomof the water feeding pipe; a gas feeding pipe is fixed on one side of the shell; one end of the gas feeding pipe penetrates through the shell and is fixed with a gas radiating device; the gas radiating device comprises a gas distributing slot, a plurality of gas radiating heads and a support frame; one end of the gas feeding pipe is connected with the gas distributing slot; the gas radiating heads are uniformly distributed at the top of the gas distributing slot; a plurality of through holes are uniformly distributed in the outer side of the gas radiating heads. The combustion exhaust gas filtering device is capable of uniformly distributing the exhaust gas in the shell through the gas radiating device and using the sprayed purified water for more thoroughly removing the dust in the exhaust gas.

Description

technical field [0001] The invention relates to the technical field of combustion exhaust gas treatment, in particular to a combustion exhaust gas filtering device. Background technique [0002] At present, many wastes are treated by incineration. Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and becomes residue or molten solid matter. [0003] In the process of garbage incineration, a large amount of waste gas will be produced, and the waste gas contains a lot of dust. If the waste gas is not treated and discharged directly into the atmosphere, it will pollute the surrounding atmospheric environment. The existing technology usually uses a spray system to remove the waste gas However, due to the uneven distribution of the exhaust gas flow, the sprinkler system cannot fully remove the dust in the exhaust gas.
