Energy-saving baking room with dehumidifying and heat accumulating function

Abstract

The invention provides an energy-saving baking room with a dehumidifying and heat accumulating function. The energy-saving baking room comprises a baking chamber and a heating chamber, wherein the baking chamber is provided with a dehumidifying port, and the heating chamber is provided with a chimney. A heating furnace and a fan are arranged in the heating chamber, and an air return port is arranged between the heating chamber and the baking chamber. The energy-saving baking room is characterized in that a dehumidifying device is arranged in the inner upper side of the heating chamber, the dehumidifying port is arranged between the heating chamber and the baking chamber and higher than the air return port, the dehumidifying device comprises a porous humidity-absorbing support plate and a humidity-absorbing plate, the humidity-absorbing plate is fixed in the heating chamber and higher than the air return port but lower than the dehumidifying port and divides the heating chamber into two spaces, and automatic adjusting windshield plates capable of moving vertically and opposite in folding and unfolding state are arranged at the air return port and the dehumidifying port. By matching the dehumidifying device on the upper portion of the heating chamber with the automatic adjusting windshield plates, dehumidifying of the baking room can be accelerated, heat can be prevented from discharging along with humidity during dehumidifying, heat waste is reduced and heat utilization rate of the baking room is effectively improved.

Description

technical field [0001] The invention belongs to a flue-cured tobacco equipment, in particular to an energy-saving barn for dehumidification and heat retention, which can accelerate the dehumidification and reduce the waste of heat caused by the dehumidification. Background technique [0002] The barn is a kind of building that is heated by fuel and bakes items. Most of the barns take away most of the heat due to the need for moisture removal, which greatly causes waste of energy such as coal, especially the humidity of the flue-cured room is particularly high. Due to the particularity of tobacco leaf curing in large barns, it needs a lot of dehumidification during the late yellowing period, color fixing period, and tendon drying period. The time can reach more than 60 hours in total, and the waste of heat is very serious, thereby causing waste of energy. Especially for dense barns with high smoke density, the smoke density is high, and there are fans for forced ventilation ...

[0002] The barn is a building that is heated by fuel and bakes items. Most of the barns take away most of the heat due to the need for moisture removal, which greatly wastes energy such as coal, especially the humidity of the flue-cured room. Due to the particularity of tobacco leaf curing in large barns, it needs a lot of dehumidification during the late yellowing period, color fixing period, and tendon drying period. The total time can reach more than 60 hours, and the waste of heat is very serious, resulting in waste of energy

Especially for dense barns with high smoke density, the smoke density is high, and there are fans for forced ventilation circulation. When the cold air door is opened to dehumidify, there will be a problem that the humid air cannot be discharged in time when it returns from the return air port, making the dehumidification Prolonged time will cause waste of heat or delay in dehumidification, resulting in roasting of tobacco leaves
