Abstract A method for disposing of combustible waste gas by burning and an apparatus embodying the method is disclosed. At the front end of a main pipe carrying waste gas are provided a plurality of branch pipes adapted to branch waste gas steppedly according to the flow rate in the main pipe. The open ends of the branch pipes are inserted into individual sections of water-sealed drums and submerged in water-seal to different depths. Between the upper portion of each water-sealed drum and a combustion furnace is provided a connecting pipe respectively to dispose individually the waste gas supplied through the connecting pipes by burning in the combustion furnace. The combustion furnace is formed of a continuous cylindrical body of several stages with a larger inner diameter at the upper stage and smaller diameters at successively lower stages. In the inner bottom of each stage and in the closed bottom of the lowermost stage and adjacent them are provided respectively disposable gas injection nozzles and air suction ports, so that combustion is to be carried out from the closed bottom of the lowermost stage.

Claim 1
Independent Claim
177 words
An apparatus for disposing of combustible waste gas carried by a main pipe, comprising: branch means connected to the main pipe for branching waste gas according to the flow rate in the main pipe; a plurality of branch pipes connected to said branch means, waste gas being channelled into at least one of said branch pipes according to the flow rate in the main pipe; a plurality of connecting pipes, one pipe communicating with each of said branch pipes for carrying waste gas therefrom, and each having a nozzle at the other end thereof; and a combustion furnace connected to said connecting pipes, said combustion furnace being a continuous cylindrical body comprised of a plurality of stages arranged in vertical order and communicating with adjacent stages, the uppermost stage having a first diameter and the diameters of successively lower stages being successively smaller than the first diameter, gas injection nozzles provided adjacent the bottom of each stage, air suction ports provided adjacent each of said gas injection nozzles and an ignition means positioned within the lowermost stage.
