ABSTRACT:
Flammable waste material and nonflammable waste material are concurrently treated in the apparatus. Flammable waste material such as oil-contaminated solids and liquids is treated by a system which in a first stage reduces the material to small particles mixed and soaked with water, then in a second stage countersprays the mixture into an oil or gas fired flame in a furnace enclosure to explode as steam the water content and consume the particles fragmented by the explosion; in a third stage any particles which are not consumed fall into a flaming pit of sand where they remain in combustion until the pit is slid out for cleaning; vapor, smoke and fumes pass from the second stage through chemical shower, water spray and forced-air stages into a vertical filter stage where coarse filtrate slides into a vat and into a horizontal filter stage in an upward chimney where a counterflow of water spray coacts to purify the exhaust and return fine filtrate into the vat; recirculation of the vat material is provided. Concurrently with the above process, nonflammable waste material is mixed with water and sprayed onto a hot plate; the resulting gaseous material then joins vapor smoke and fumes of the flammable waste material for treatment in the chemical shower and succeeding stages.
