Title: PURIFICATION DEVICE
Abstract:
This purification device purifies flue gas produced by combustion to warm a greenhouse for growing plants. The purification device is provided with a flue gas flow passage, a flow-down part, and a cooling part. The flue gas flow passage is a flow passage that allows flue gas to flow down in a predetermined flow-down direction, and has a cooling zone in which the flow becomes oriented downward as the flue gas moves in the flow-down direction. The flow-down part introduces flue gas produced by combustion into the flue gas flow passage so as to cause the flue gas to flow down in the flow gas passage in the flow-down direction. The cooling part cools the flue gas flowing down through the cooling zone.
