A high-temperature tunnel furnace steam-assisted heating energy-saving device

Abstract

The present invention discloses a steam-assisted heating energy-saving device for a high-temperature tunnel furnace, which relates to the technical field related to tunnel furnaces. The key points of the technical solution are a steam-assisted heating energy-saving device for a high-temperature tunnel furnace, comprising a machine body, a furnace body, an air recovery mechanism, a steam heating mechanism, and an air delivery mechanism. By providing the steam heating mechanism, the baking efficiency is improved. By rotating the nozzle, the air sent into the baking chamber through the air outlet pipe can be evenly distributed throughout the baking chamber, thereby improving the temperature uniformity in the baking chamber. In addition, the orientations of the two adjacent air outlet pipes are opposite, which can further improve the temperature uniformity in the baking chamber, thereby improving the baking pass rate and baking efficiency. This solves the problem that in traditional tunnel furnaces, the baking process is achieved by supplementing fresh air from the air inlet and heating the fresh air directly into the furnace body through an electric heating pipe, resulting in uneven temperature inside the furnace body, thereby reducing the baking pass rate and baking efficiency.
