Crude gas and slag are conducted downward into a water bath in a central tube. The upper part of the central tube consists of a double-threaded tube screen welded in a gas-tight manner, in which water is injected directly as the first scrubbing and cooling stage in the interior thereof. In the water bath, a bubble column is formed, which simultaneously constitutes the second scrubbing and cooling stage. Surface bodies arranged in three layers increase the scrubbing effect. After leaving the bubble column, the crude gas is again sprayed with water in a cavity, wherein one or more nozzle rings are disposed. This forms the third scrubbing stage. The crude gas then leaves the quenching and scrubbing apparatus in steam-saturated form at 200-220° C. and is sent to further treatment. | 03-19-2015 |
