Embodiment Construction
[0015] Below in conjunction with the accompanying drawings, the present invention will be further described through embodiments
[0016] A waste heat utilization equipment for coke oven waste gas, comprising a riser 1, a double-layer casing 2 composed of an inner pipe 4 and an outer pipe 3, an inlet 5 and an outlet 6 of the double-layer casing on the riser shell, and a double-layer casing. A closed space is formed between the outer tube and the inner tube of the casing. The closed space is called interlayer. The double-layer casing enters the riser through the inlet through the riser shell. At the outlet, the inner tube of the double-layer casing is a flowing process medium, and the heat conduction medium is placed in the interlayer. The high-temperature waste gas in the coke oven rising tube transfers heat to the heat conduction medium through the outer tube, and the heat conduction medium transfers the heat to the process medium through the inner tube. .
[0017] The riser ...
