Patent ID: 7862632

Claim:
A multi-burner gasification reactor for gasification of slurry or pulverized hydrocarbon feed materials, with an upright cylindrical vessel ( 1 ) including a refractory lining layer therein, said reactor further comprising: a brick-supporting plate ( 6 ), disposed in the middle of the upright cylindrical vessel ( 1 ), dividing said upright cylindrical vessel ( 1 ) into an upper gasification chamber ( 2 ) and a lower scrubbing and cooling chamber ( 3 ), n pairs, wherein 2â‰¦nâ‰¦10, of gasification burner chambers ( 5 ) disposed on a periphery of said gasification chamber ( 2 ), each pair of said chambers ( 5 ) being symmetrically opposed and meeting at 180 degrees, with an axis of each of said chamber ( 5 ) being at an angle of 1-10 degrees downward relative to the horizontal plane, located at planes with a distance (H) to the top of the reactor vessel being 1Ëœ2 times of an inner diameter (D i ) of said vessel ( 1 ), and being able to be set as one, two or three layers, a gasification burner ( 7 ) disposed in the gasification burner chamber ( 5 ), which is coaxial with the gasification burner chamber ( 5 ), a fire-end profile of said gasification burner chamber ( 5 ) being a bell mouth, and an end of the gasification burners ( 7 ) being shorter than that of a refractory lining, strip cooling fins ( 17 ) disposed at an outer side of the gasification reactor vessel ( 1 ) where a brick-supporter shelf ( 16 ) is installed, a syngas and slag outlet ( 24 ) disposed in a center of said brick-supporting plate ( 6 ), a flow area of which being designed based on a medium flow rate of 5-10 m/s, a water jacket ( 14 ) disposed on a back side of said brick-supporting plate ( 6 ), a syngas and slag tube ( 11 ) disposed at a lower part of said syngas and slag outlet ( 24 ) and inserted into said scrubbing and cooling chamber ( 3 ), the syngas and slag tube ( 11 ) being coaxial with the gasification reactor, a cooling water ring ( 10 ) disposed at a center of the brick-supporting plate ( 6 ) and fixed to said brick-supporting plate ( 6 ), a syngas outlet ( 13 ) formed at an upper portion of said syngas scrubbing and cooling chamber ( 3 ), a black water outlet ( 19 ) formed at a lower portion of said syngas scrubbing and cooling chamber ( 3 ), a slag water outlet ( 15 ) formed at a bottom of said syngas scrubbing and cooling chamber ( 3 ), and a high pressure nitrogen blow pipe ( 21 ) set at the lower portion of said syngas scrubbing and cooling chamber ( 3 ) and in the syngas and slag tube ( 11 ).
