Description

Technical Field

[0001] The utility model relates to the technical field of drying furnaces, and specifically to an energy-saving drying furnace. Background Art

[0002] When performing the drying operation of products, it is usually carried out in the corresponding drying furnace. There are many types of drying furnaces on the market. Some drying furnaces are used to convey hot air to the outside for drying operations, and some drying furnaces directly place the materials to be dried inside and directly carry out the drying operation in the drying furnace.

[0003] Since heat steam is generated during the drying process, at this time, most drying furnaces are provided with moisture discharge pipes, so that the heat steam can be discharged outward along the moisture discharge pipes. However, most moisture discharge pipes are directly connected to the outside, resulting in the direct discharge of the heat steam to the outside. The heat of this part of the heat steam discharged into the air will cause waste of heat energy. Most drying furnaces cannot recover and utilize the heat in the discharged heat steam, which is not conducive to achieving the energy-saving effect. In view of this, we have proposed an energy-saving drying furnace. Summary of the Utility Model
