AI Technical Summary

⚠Technical Problem

Existing rotary dehumidifiers have high energy consumption costs in the lithium battery production process, mainly concentrated in the cooling of the surface cooler and the heating of the regenerated fresh air, and there is also a waste of cold and hot energy.

⚗Method used

By adding heat pipes and heat pump systems to the rotary dehumidifier, the heat pipes pre-cool and preheat the air in the fresh air duct, reducing the energy consumption of the surface cooler and regeneration heater; the heat pump system cools and dehumidifies the air in the fresh air duct and heats the air in the regeneration duct, realizing energy recovery and reuse.

🎯Benefits of technology

It reduces the operating energy cost of rotary dehumidifiers, improves energy utilization, reduces the waste of cold and heat energy, and enhances dehumidification efficiency.

Abstract

The application discloses a rotary dehumidifier, and relates to the technical field of dehumidifying equipment. The rotary dehumidifier comprises a fresh air duct, a regeneration air duct, a dehumidifying runner, a first surface cooler, a heat pipe and a heat pump system. The air inlet end of the regeneration air duct is communicated with the fresh air duct. The dehumidifying runner comprises a dehumidifying area and a regeneration area. The dehumidifying area is communicated with the fresh air duct, and the regeneration area is communicated with the regeneration air duct. The first surface cooler is arranged in the fresh air duct and located at the front end of the dehumidifying area. A regeneration heater is arranged in the regeneration air duct and located at the front end of the regeneration area. The heat pipe is arranged in the fresh air duct and configured to cool the air before the air flows into the first surface cooler and heat the air before the air flows into the regeneration air duct. The application can reduce the energy consumption cost of the rotary dehumidifier.
