Detailed ways

In this embodiment, as shown in Fig. 1 to Fig. 2, the high-efficiency air source low-carbon tobacco drying equipment includes a heating system and a tobacco flue-curing room connected to the heating system; the flue-cure room is provided with a heat pump auxiliary machine 14, Air intake door 15, circulation fan 16, hot air supply port 18, tobacco rack 19, flue-cured tobacco chamber 21, air return port 26 and moisture discharge port 27; connecting pipe 13 is arranged between the heating system and heat pump auxiliary unit 14 to connect. Making equipment more energy-efficient, more efficient, more environmentally friendly, and truly zero-pollution has important promotion significance for the current two-tobacco policy.

Wherein, the heating system includes a heat pump circulation fan 1, an evaporator 2, a low pressure switch 3, a four-way valve 4, an electric control box 5, a high pressure switch 6, a liquid storage tank 7, a heat pump circulation fan 8, a waste heat recovery pipe 9, a low pressure Switch 10, electronic expansion valve 11 and filter 12. The liquid storage tank is provided with a waste heat recovery device, which not only has the function of liquid storage, but also has the function of waste heat recovery. The tobacco curing room is also provided with a door 22 and an inspection window 17 . Both the side wall and the top wall of the flue-curing room are thermal insulation boards 20 . The tobacco curing room is also provided with a front door observation window 23, a bottom observation window 24, and a high-level observation window 25.

When working, the heat pump circulation fan 1 starts, and the compressed high-temperature and high-pressure medium passes through the heat pump auxiliary machine 14, and releases high-temperature heat into the flue-cured tobacco room. The unreleased heat enters the waste heat recovery pipe 9, throttles through the electronic expansion valve 11, and enters the evaporator 2 to absorb air. The heat in the heat is returned to the liquid storage tank 7, and finally returns to the heat pump circulation blower 1 to work in circulation.

The circulation fan 16 sends the air heated by the heat pump auxiliary machine 14 to the flue-cured tobacco room through the hot air supply port 18, so that the temperature of the flue-cured tobacco room is gradually increased, and the low-temperature air after the tobacco leaves absorb heat returns to the air return port 26, and then passes through the heat pump auxiliary machine 14. Heating, hot air is sent into the tobacco flue-curing room again by the circulation fan 16, and returns to work.

According to the needs of the tobacco leaf curing process, it is set/identified by the controller, and controls the rise and fall of the dry bulb temperature and the wet bulb temperature; a. When the dry bulb temperature exceeds the set temperature, the heating system stops heating; The heating system starts heating at a fixed temperature; b. Wet bulb temperature control: When the wet bulb temperature is higher than the set value, the air inlet door will be opened automatically to fill in fresh air, so that the flue-cured tobacco room will form a positive air pressure, and the original humidity in the room will be reduced. Heavier air is extruded from the humidity outlet; when the wet bulb temperature in the flue-cured tobacco chamber reaches or falls below the set value, the air inlet door is automatically closed, and the cycle repeats to make the temperature and humidity in the flue-cured tobacco chamber always meet the technical requirements of the flue-cured tobacco.

The utility model's high-efficiency air source low-carbon tobacco drying equipment solves the traditional problems of high pollution, high energy consumption, high labor cost, and coal-based flue-cured tobacco in China and the world today. The design of the machine not only solves the problem of air Among them, the new technology of renewable energy adopts waste heat recovery in the liquid storage tank itself, making the equipment more energy-saving, more efficient, more environmentally friendly, and truly zero-pollution, which has an important promotion for the current two-cigarette policy significance.

The utility model has been described in detail above. The above description is only a preferred embodiment of the utility model. When it cannot limit the scope of the utility model, all equivalent changes and modifications made according to the scope of the application should be Still belong to the scope covered by the present utility model.
