[0002] For food, tea, medicinal materials, and sludge drying, the most common drying equipment is fuel dryers, which use wood, coal, natural gas, etc. as fuel. Not only is the drying efficiency low and the cost high, but a large amount of harmful gases will be released during the drying process, polluting the environment. When exploring new development paths for drying technology, energy efficiency, environmental protection, and product quality should be comprehensively considered, and a development strategy for efficient and green drying should be implemented. Not only should the drying process be fundamentally transformed, but also comprehensive and multi-level energy-saving technology transformation should be carried out, and drying technology using renewable energy and industrial waste heat should be vigorously developed. After more than ten years of development, the field of air energy heat pumps has formed a certain market scale and presented the characteristics and trends of industrial development. As a new and energy-saving new technology, air energy has largely solved the problems of low traditional drying efficiency and high drying costs. Coupled with the intentional support of local governments, heat pump drying has been developing rapidly in major provinces in my country and is widely used in industrial manufacturing, agricultural production, commerce, daily life and other major fields. During the drying process, it is necessary to control some fine, dry, fibrous dust and non-fibrous dust in the drying room to meet environmental emission standards.

[0028] The hot dry air heated by the drying unit 1 enters the heat preservation drying room 2 through the air outlet duct 51 to heat the materials. The hot and humid air carrying impurities such as water vapor and dust enters the bag dust removal component 3 at the top of the drying room 2. After filtering out the impurities, the hot and humid air returns to the drying unit 1 through the return air duct 52. The hot air after drying and heating is sent to the heat preservation drying room again.

[0029] Example 2: See Figure 1Figure 6: As shown in Schematic Diagram 2 of the arrangement method of dust bags in the drying room, the hot dry air heated by the drying unit enters the thermal insulation drying room through the air outlet duct to heat the materials, and the hot and humid air carrying impurities such as water vapor and dust enters the bag dust removal assembly on the roof of the drying room. After filtering out the impurities, the hot and humid air returns to the drying unit through the return air duct, and the hot air after drying and heating is sent to the thermal insulation drying room again.
