Description

Technical Field

[0001] The utility model relates to the technical field of textile printing and dyeing machinery, in particular to a dehumidification and heat recovery device used in a textile printing and dyeing oven. Background Art

[0002] The textile printing and dyeing oven uses hot air to dry the moisture of the fabric after printing or washing. The drying efficiency depends on the wind speed of the circulating fan, the temperature of the hot air, the drying time and the humidity in the oven. The higher the wind speed of the circulating fan, the higher the temperature of the hot air and the longer the drying time, the higher the drying efficiency. The lower the humidity in the oven, the higher the drying efficiency. The existing ovens improve the drying efficiency of the oven by increasing the length of the oven and the temperature of the hot air in the oven. The treatment of the humidity in the oven is often achieved by a simple direct exhaust method. A plurality of exhaust ducts are installed on the top of the oven, and the exhaust ducts converge into the exhaust duct. The moisture in the drying room is discharged through the exhaust fan. While discharging the moisture in the oven, a large amount of heat energy is also discharged. The exhaust temperature can be as high as more than 100 degrees, which greatly wastes heat energy. If the exhaust volume is reduced, the drying efficiency of the oven will be greatly reduced due to the high humidity in the oven. This leads to the problem that in order to improve the drying efficiency of the oven, the temperature of the oven is increased. However, the increase in drying temperature will greatly increase the loss of heat energy. At the same time, increasing the exhaust volume and reducing the humidity in the oven will cause a large amount of heat energy to be discharged, wasting energy.

[0003] Based on this, the utility model designs a dehumidification and heat recovery device for a textile printing and dyeing oven to solve the above problems. Utility Model Content

[0021] The heat exchange box 3 includes a heat exchange box body 31 connected to the oven body 1. The middle part of the inner cavity of the heat exchange box body 31 is separated by a partition 32. The partition 32 divides the inner cavity of the exchange box body 31 into an exhaust chamber 33 and an air intake chamber 34.
