[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0028] The invention adopts spray chilling and air jet protection in a tangential arrangement, and by adjusting the amount of cooling water, the high-temperature (1350-1650°C) synthesis gas at the outlet of the gasifier can be chilled and the slag can be solidified. The cooling load is large and the cooling gas consumption is small.
[0029] Such as figure 1 As shown, the synthesis gas quenching device includes a coal gasifier 1, a quenching chamber 2, a synthesis gas conduit 3, where the quenching chamber 2 is a space formed by a circular, rectangular or polygonal section moving along the norm...
