Drying room afterheat recycling device

Abstract

The invention discloses a drying room afterheat recycling device. The device comprises a heat exchanging body, wherein the heat exchanging body comprises a shell, a fresh air passage and a hot waste air passage which are arranged inside the shell; a heat exchanging device is arranged between the fresh air passage and a hot waste air passage; the heat of waste air which flows through the hot waste air passage can be absorbed by utilizing a heat exchange theory. By utilizing a circulating heat conduction and exchange theory, the drying room afterheat recycling device disclosed by the invention is capable of realizing recycle of waste heat, energy-saving and environment-friendly; the drying room afterheat recycling device disclosed by the invention is of a square box type structure and is simple in structure, convenient to wash and maintain and small in floor space by being placed above a drying room; the temperature of a pipeline wall can be reduced by the waste air after the waste air passes through the afterheat recycling device; heat radiation caused by the temperature of a waste air exhausting system to the air can be reduced; the comprehensive energy conservation is about 20%.

Description

technical field [0001] The invention relates to the field of heat energy recovery devices, in particular to a drying room waste heat recovery device. Background technique [0002] At present, in the entire field of baking in the baking room, almost all baking equipment uses the low humidity and low temperature air outside the baking equipment to directly exchange the high humidity and high temperature moisture inside the equipment to bake the materials in the equipment. , Dehumidification. Although this technology can achieve the effect of dehumidification, in the process of dehumidification, because the dehumidification air contains a lot of heat, it cannot be recycled, and a large amount of heat energy is lost in the air outside the equipment, resulting in a large waste of energy. It has not been effectively utilized, resulting in a large energy consumption in the drying room during the baking operation. Contents of the invention [0003] Aiming at the deficiencies of ...
