Patent ID: 7566049

Claim:
Gas cooling device for coke oven gas that contains condensing constituents, having a gas channel ( 6 ) through which coke oven gas flows, and cooling plates ( 5 ) through which a coolant flows, which are combined to form at least one heat exchanger package with channel-forming spacers ( 7 ), whereby the heat exchanger package is disposed in the gas channel ( 6 ) with a vertical orientation of the cooling plates ( 5 ), and a sprinkling device ( 2 ) is provided above the heat exchanger package, wherein the coke-oven gas flows through the gas channels formed by the spacers ( 7 ), and that the liquid that exits from the sprinkling device ( 2 ) is applied to them, so that the gas-side heat-exchanger surface of the cooling plates ( 5 ) is wetted with liquid and a film of liquid forms on the heat-exchanger surface, which transports away constituents that condense out of the coke-oven gas, and that the heat exchanger package can be inserted laterally into the gas channel ( 6 ), as a replacement unit.
