Problems solved by technology

[0002] The dryer is under the suction of the fan, and the fresh cold air outside directly passes through the air inlet to exchange heat with the heater and then becomes dry hot air, and then exchanges heat with the object to be dried and is discharged from the body. The moisture in the medium evaporates, so the exhaust air of the dryer contains a lot of moisture and heat. This hot and humid air is directly discharged into the air, which will waste a huge amount of energy

Abstract

The invention discloses a heat recovery unit of a moist and hot air exhaust dryer. A heat exchange pipe moist and hot air channel and a heat exchange pipe dry and hot air channel are coaxially arranged in a heat exchange pipe. The heat exchange pipe moist and hot air channel communicates with a moist and hot air suction assembly. The heat exchange pipe dry and hot air channel communicates with a dry and hot air suction assembly. The flow directions of the heat exchange pipe moist and hot air channel and the heat exchange pipe dry and hot air channel in the heat exchange pipe are opposite. According to the heat recovery unit, heat in moist and hot air can be recovered well, recovered dry and hot air is made to return to the dryer, part of energy can be effectively recycled, the utilization rate of the energy is greatly increased, cost is reduced, and the environment is saved. In addition, the heat recovery unit is novel and compact in structure, the heat recovery effect can be greatly improved, and the recovery energy of the dry and hot air can be enhanced through the opposite flow directions of the heat exchange pipe moist and hot air channel and the heat exchange pipe dry and hot air channel. Meanwhile, heat conduction sheets of the heat recovery unit can carry out heat conduction better, and the energy recovery effect of the dry and hot air is enhanced.

Description

technical field [0001] The invention belongs to the technical field of heat recovery, and in particular relates to a heat recovery device for a hot and humid air exhaust dryer. Background technique [0002] The dryer is under the suction of the fan, and the fresh cold air outside directly passes through the air inlet to exchange heat with the heater and then becomes dry hot air, and then exchanges heat with the object to be dried and is discharged from the body. The moisture in the medium evaporates, so the exhaust air of the dryer contains a lot of moisture and heat. This hot and humid air is directly discharged into the air, which will waste a huge amount of energy. [0003] Therefore, how to effectively utilize the energy in the hot and humid air and realize heat recovery is of great significance for saving energy and reducing energy consumption costs. Contents of the invention [0004] Aiming at the existing technical problems, the present invention provides a heat re...
