The utility model discloses a steam box with an
energy recovery function. Comprising a support and a steam box fixed on the support and further comprises a steam generator, a pressure relief main
pipe connected with the steam generator and a steam
heat exchanger connected with the pressure relief main
pipe through a first pressure relief
branch pipe, and each steam chamber of the steam box is connected with the steam generator through a steam pipe. Each steam chamber of the steam box is further connected with a pressure relief main pipe through a second pressure relief
branch pipe, the second pressure relief
branch pipe is connected with a one-way valve, the steam pipe is provided with a steam valve, the outlet end of the pressure relief main pipe is connected with a pressure
relief valve, and the end, located on the steam generator, of the pressure relief main pipe is connected with a steam speed increasing pump. During operation, the steam
heat exchanger is used for recovering
latent heat of bled steam, energy waste is avoided, and
energy recycling is achieved; the steam speed increasing pump ensures stable circulating supply of steam, the
steaming quality is guaranteed, all valves are reasonably arranged, the pressure and the flow direction of the steam are effectively controlled, and equipment damage and safety accidents are prevented.
