MODE OF REGENERATION OF A DRYING AGENT OF CONVECTIVE DRYERS Russian patent published in 2005 - IPC

FIELD: the invention refers to technique of controlling temperature of air or gases for drying solid materials or objects.

SUBSTANCE: new in the mode of regeneration of a drying agent of convective dryers which includes heat exchange between the drying agent and liquid sorbent for changing temperature of the drying agent and recovery of the sorbent's concentration is that in the process of heat exchanging between the drying agent and the liquid sorbent the sorption heat is used for heating the drying agent fed into the dryer and recovery of sorbent's concentration is carried out by multistage evaporation at putting heat exchange between sorbents of different concentrations into effect. At that the movement of the drying agent in the dryer is made in closed contour.

EFFECT: the invention must ensure increasing degree of using of the heat of the drying agent at the expense of using the sorption water steam heat.
