Provided is a coal distilled gas hot treatment facility that distills carbon-containing solids by heat-treating coal distilled gas steam extracted from a plurality of coal distilling devices at an inflow temperature of 700°C to 1200°C, and comprises: a gas extraction pipe provided to each of the coal distilling devices; a non-return valve provided to each of the gas extraction pipes; a collection pipe connected by the gas extraction pipes; and a coal distilled gas treatment device connected to the collection pipe. The gas extraction pipes, the non-return valves, the collection pipe, and the coal distilled gas treatment device are provided in an atmosphere that has been heated to a temperature of 700°C to 1200°C, and the coal distilled gas flows through the coal distilling devices, the gas extraction pipes, the non-return valves, the collection pipe, and the coal distilled gas treatment device, in that order. |
