A drying room and a dehydration method using the drying room

Abstract

The invention discloses a drying room and a method for dehydration through the drying room. The drying room comprises an air freshening machine dew point cooler, an oscillating heat pipe, a duplex electric air valve, an exhaust air waste heat recovery wind cabinet, surface air coolers and fans; and an air inlet is formed in an entrance of the drying room, and an air exhaust port is formed in the drying room. The invention further provides the method for dehydration through the drying room. After entering the drying room, fresh air carries out heat exchange with the air freshening machine dew point cooler and then carries out heat exchange with the oscillating heat pipe, air on the top of the drying room carries out heat exchange with the surface air coolers and then carries out heat exchange with the oscillating heat pipe, and therefore the air can be cooled; and heat of cold water is absorbed after the cold water passes through the air freshening machine dew point cooler, the surface air coolers and the oscillating heat pipe, and therefore energy-saving production of air dehydrating and drying can be realized.

Description

technical field [0001] The invention relates to the field of hot air drying equipment, in particular to a drying room and a dehydration method using the drying room. Background technique [0002] In the hot air drying method, there will be various heat losses, convective heat loss is one of them, convective heat refers to the relative displacement between various parts of the fluid caused by the macroscopic movement of the fluid, caused by the intermixing of cold and hot fluids Convection heat transfer can be divided into forced convection and natural convection. Forced convection is the circulation of fluid driven by external forces. Natural convection is due to the change of density gradient at different temperatures and gravity. Flow from top to bottom, high-temperature density fluid flows from bottom to top, the heat loss generated in the process of convective heat transfer is convective heat loss, the usual convective heat loss is latent heat, sensible heat enclosure he...

[0002] In the hot air drying method, there will be various heat losses, convective heat loss is one of them, convective heat refers to the relative displacement between various parts of the fluid caused by the macroscopic movement of the fluid, caused by the intermixing of cold and hot fluids Convection heat transfer can be divided into forced convection and natural convection. Forced convection is the circulation of fluid driven by external forces. Natural convection is due to the change of density gradient at different temperatures and gravity. Flow from top to bottom, high-temperature density fluid flows from bottom to top, the heat loss generated in the process of convective heat transfer is convective heat loss, the usual convective heat loss is latent heat, sensible heat enclosure heat in the drying process The sum of losses is more than twice, and the existing devices used to deal with the convective heat loss phenomenon only recover part of the heat discharged by convection, which has low efficiency, large energy consumption and environmental damage
