Energy-saving tobacco flue-curing house capable of effectively recycling dehumidification heat energy

Abstract

The invention discloses an energy-saving tobacco flue-curing house capable of effectively recycling dehumidification heat energy, which comprises a heating chamber and a tobacco flue-curing chamber. The heating chamber is communicated with a chimney. A heating furnace chamber is arranged at the lower part of the heating chamber. A circulating air chamber is arranged at the upper part of the heating chamber. A furnace mouth, an ash outlet and an air blowing port are arranged at the front part of the heating furnace chamber. The air blowing port is connected with an air blower. Dehumidification passages are arranged on the two sides of the bottom of the heating furnace chamber. Cold air inlets are arranged above the dehumidification passages. A circulating fan repair passage is arranged at the front part of the circulating air chamber. High-efficiency heat exchange devices are arranged in the dehumidification passages. The dehumidification pipes of the heat exchange devices are communicated with a waste heat utilization device. The dry air pipes of the heat exchange devices are communicated with dry air inlets. The energy-saving tobacco flue-curing house capable of effectively recycling dehumidification heat energy has the advantages that since the high-efficiency heat exchange devices are directly arranged in the dehumidification passages to realize heat exchange between high-temperature moisture exhausted from the tobacco flue-curing house and normal-temperature fresh air, the heat in dehumidification air can be fully recovered and directly used as an auxiliary heat source for the tobacco flue-curing house, and the temperature of inlet air which enters the heating chamber can be increased by more than 10DEG C.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf curing and energy saving, and in particular relates to an energy-saving tobacco flue-curing room capable of effectively recovering the moisture-discharging heat energy of the tobacco-leaf curing room and realizing the purpose of saving energy and reducing consumption. Background technique [0002] Tobacco leaf curing process requires timely dehumidification of the barn. The humidity in the unit barn in the prior art is directly discharged into the atmosphere through the dehumidification channel. The temperature of the hot and humid air is mostly above 40°C, even as high as 70°C, and is directly discharged into the atmosphere. It not only pollutes the environment, but also causes a waste of energy. The inventor of the present invention has developed a unit barn that can recycle and utilize the heat energy of dehumidification, but since the heat exchange equipment is external, the efficiency of...

[0002] Tobacco leaf curing process requires timely dehumidification of the barn. The humidity in the unit barn in the prior art is directly discharged into the atmosphere through the dehumidification channel. The temperature of the hot and humid air is mostly above 40°C, even as high as 70°C, and is directly discharged into the atmosphere. Not only pollute the environment, but also cause a waste of energy

The inventor once developed a unit barn that can recycle and utilize the heat energy of dehumidification, but because the heat exchange equipment is external, the efficiency of heat energy recovery is low

Moreover, the fresh air after heat exchange needs a long pipeline to enter the air inlet, which will cause the loss of recovered heat energy
