COUNTERCURRENT RECOVERING DEVICE FOR TENTER MACHINE RECOVERING WASTE HEAT OF HIGH TEMPERATURE GAS WITH SWIRL FLOW AND REMOVING OIL MIST

摘要

The present invention relates to a waste heat recovery technology, and more particularly, to a countercurrent recovery device for a tenter device capable of removing waste heat and high-temperature gas from a swirling flow. According to embodiments of the present invention, the waste heat of the gas generated in the tenter can be recovered through heat exchange and recycled again in the production process, and the number of swirl flows when the gas descends from top to bottom while turning inside the heat exchange tube Increases to increase the heat exchange efficiency, and the gas flow can also be removed due to swirl flow.
