Problems solved by technology
[0003] (1) Coal is still used for heating, which has high cost and low utilization rate;
[0004] (2) The baked hot air is directly discharged into the air, causing a waste of energy;
[0005] (3) The temperature distribution of tobacco leaf curing is somewhat improved compared with that of ordinary tobacco leaf curing room, but the distribution is still not uniform enough to satisfy the production of high-grade tobacco with a large ratio.
[0006] (4) The safety of heating with coal furnace is not high, and there is a certain danger of explosion;
[0007] (5) Repeated use of hot air, the humidity in the air is high, not suitable for long-term baking
According to the experiments, compared with the traditional intensive tobacco barns, these barns still have uneven heating air, uneven temperature distribution in the barns, and no use of waste heat.
[0010] In general, most of the current solar-powered tobacco-curing rooms still directly heat the air through solar energy, and have not improved the heating method to improve heating efficiency. At the same time, they lack waste heat utilization systems, and the energy utilization rate is low. Disorganized and poorly directed airflow

Embodiment Construction
[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0027] as attached figure 1 The shown is an energy-saving tobacco leaf curing room using solar energy. The solar energy is used as the heat source for drying the tobacco leaf curing room. It includes three modules: a solar heating device module, a tobacco leaf curing room module, and an exhaust waste heat recovery module.
[0028] The solar heating device module includes a solar heating heat storage water storage tank 1, a valve 101, a circulating water pump 2, a first flow meter 3, a first thermometer 4, a valve two 102, a valve three 103, a second flow meter 5, a second Thermometer 6, valve four 104. This module sends the cold water to the solar heating storage tank 1 after being heated by the solar heater, and the water is pressurized and sent...

The invention discloses an energy-saving tobacco leaf curing house utilizing solar energy. The energy-saving tobacco leaf curing house comprises a solar heating device module, a tobacco leaf curing house module with an air-water heat exchanger, and an exhaust and waste heat recycling module with an air-air heat exchanger. Heated hot water meeting the requirement flows into the inlet end of the air-water heat exchanger of the tobacco leaf curing house module through the solar heating device module; air obtained after heat exchange is fed into a curing house body through the tobacco leaf curing house module. Air exhausted out of the curing house body enters the exhaust and waste heat recycling module, passes through the air-air heat exchanger and is used for preheating fresh air fed into the tobacco leaf curing house module. Solar energy and exhaust heat are fully utilized, the energy-saving tobacco leaf curing house is clean and environmentally friendly, a flow guide plate is designed in the curing house, an airflow structure in the curing house is improved, the contact area of the hot air and tobacco leaves is increased, the drying efficiency is improved, and the yield of the tobacco leaves is increased.
Description
technical field [0001] The invention relates to a tobacco leaf curing room, in particular to an energy-saving tobacco leaf curing room which utilizes solar energy for heating and exhaust air. Background technique [0002] The general tobacco leaf curing room is divided into traditional intensive tobacco leaf curing room and new energy curing room. The traditional intensive tobacco leaf curing room that is widely used now has the following problems: [0003] (1) Coal is still used for heating, which has high cost and low utilization rate; [0004] (2) The baked hot air is directly discharged into the air, causing a waste of energy; [0005] (3) The temperature distribution of tobacco leaf curing is improved to some extent compared with the ordinary tobacco leaf curing room, but the distribution is still not uniform enough to meet the production of high-grade tobacco with a large ratio. [0006] (4) The safety of heating with coal furnace is not high, and there is a certain ...
