Gas-liquid separation device of hydrogen reduction furnace and hydrogen reduction furnace

The utility model discloses a gas-liquid separation device of a hydrogen reduction furnace and the hydrogen reduction furnace. The gas-liquid separation device of the hydrogen reduction furnace comprises a pipe body formed by fixedly connecting a first pipe cavity and a second pipe cavity, a heat exchange pipe is arranged in the first pipe cavity, one end of the heat exchange pipe communicates with the second pipe cavity, and the other end of the heat exchange pipe extends out of the first pipe cavity. The first pipe cavity is further communicated with a condensate water inlet and a condensate water outlet, and the second pipe cavity is communicated with a gas outlet and a liquid outlet. The hydrogen exchanges heat with condensed water introduced into the first pipe cavity in the conveying process in the heat exchange pipe, so that acid liquor mixed in the hydrogen releases heat and is condensed, and the acid liquor and the hydrogen are finally and completely separated in the second pipe cavity and are discha
