Abstract

The invention discloses an energy-saving heat pump dehumidification drying device, comprising a circulating air duct and a fan, wherein a first evaporator, a first condenser and a second condenser are arranged in the circulating air duct in accordance with the direction from an air inlet to an air outlet. The device integrates mechanical dehumidification and heat pump heating into a whole, and adopts two-level heating so as to improve the temperature in a drying room and reduce the humidity in the drying room simultaneously, thus the material drying is fast, the production efficiency is improved effectively, the economic energy-saving effect is outstanding, and the energy-saving effect is at least 50% higher than that of a common heating drying way by using an air source. Because the set is heated indirectly, electric sparks and other combustion sources are not generated, three wastes are not emitted, the noise is low and the safety and environmental conservation are ensured.

Description

technical field [0001] The invention relates to an air source heat pump dehumidifying and drying equipment. Background technique [0002] Drying equipment is widely used in food manufacturing, pharmaceuticals, agriculture, and dangerous goods processing in high-risk industries, such as gunpowder production, fireworks production, etc. The existing steam heating, indirect combustion (oil, gas), direct combustion and other heating methods have a lot of disadvantages such as low thermal efficiency, large consumption of human resources, and low safety and environmental protection. At the same time, in the past, the temperature of general drying equipment rose slowly during the drying process, and the maximum temperature was too low. The humidity in the drying material cannot be dehumidified mechanically, but can only be evaporated by hot air. The drying time is too long, the energy consumption is huge, and the types of materials that can be dried are single. [0003] Although ...
