A gasification reactor for organic solid waste

Abstract

The application discloses a gasification reactor of organic solid waste, and the inner cavity of the reactor body comprises a dense phase zone, a pyrolysis zone and a combustible gas ascending zone above the dense phase zone and the pyrolysis zone; the bottom of the dense phase zone is communicated with a wind distribution plate; the combustible gas ascending zone is provided with a raw material inlet and an inclined inner wall for receiving the raw material and pyrolyzing the raw material under the action of heat; the raw material inlet is arranged above the inclined inner wall and is connected with the side edge of the wind distribution plate of the dense phase zone; and the inclined inner wall is inclined from the bottom to the top and away from the dense phase zone, so that a pyrolysis zone connected with the dense phase zone but having a lower degree of air flow disturbance is formed; the raw material enters the combustible gas ascending zone through the raw material inlet and slides downward along the inclined inner wall under the action of gravity and enters the pyrolysis zone; the raw material is heated, pyrolyzed and releases a large amount of combustible gas in the process; the combustible gas rapidly escapes from the combustible gas ascending zone upward, has a low combustion loss ratio after contacting oxygen in the air and is beneficial to improving the calorific value of the combustible gas.
