Electric boiler tobacco curing barn with double hydrothermal circulation systems

The utility model discloses an electric boiler tobacco curing barn with double hydrothermal circulation systems. The electric boiler tobacco curing barn comprises a first-stage hydrothermal circulation device, a tobacco curing chamber and a second-stage hydrothermal circulation device, the first-stage hydrothermal circulating device, the second-stage hydrothermal circulating device and the flue-cured tobacco chamber are sequentially communicated through a heat preservation pipeline; a single group or a plurality of groups of first-stage hydrothermal circulating devices are arranged; the first-stage hydrothermal circulating device is responsible for efficiently and rapidly heating water, and the second-stage hydrothermal circulating device is mainly used for recycling waste heat; the two-stage hydrothermal circulating device can reduce the electricity consumption of electric flue-cured tobacco, the waste heat recycling efficiency is improved, meanwhile, due to separation of waste heat recycling circulation and
