Internal-circulation bulk curing barn realizing complementation of multiple energies

Abstract

The invention discloses an internal-circulation bulk curing barn realizing complementation of multiple energies. The internal-circulation bulk curing barn comprises four parts, including a tobacco loading chamber, a heating chamber, a dehumidifying chamber and a system master controller, wherein three heat transfer devices in the heating chamber carry out heat exchange with air in the heating chamber by adopting solar energy, air energy and electric energy, with the tobacco loading chamber, damp and hot air separating out in the tobacco leaf curing process is exhausted into the dehumidifying chamber for cooling and dehumidification, the damp and hot air after cooling and dehumidification returns to the heating chamber to be heated, and the system provides heat and eliminates humidity by adopting the complementation method according to the baking process curve and the temperature and humidity in the tobacco loading chamber. The internal-circulation bulk curing barn realizing complementation of multiple energies has the beneficial effects that a heat source is provided in a complementation manner by adopting four energies including solar heat collection, air energy, solar photovoltaic and electric energy, the dehumidification manner combining internal-circulation dehumidification and total heat recovery dehumidification is adopted, thus the curing cost can be reduced, the temperature rise time can be shortened, the system master controller is adopted for realizing control, so that the manual operation can be reduced, the labor intensity can be alleviated, the control precision can be promoted, and the tobacco leaf curing quality can be improved.

Description

technical field [0001] The invention belongs to tobacco leaf curing equipment, in particular to a multi-energy complementary internal circulation intensive curing barn which utilizes clean energy and adopts energy complementary heating. Background technique [0002] Tobacco leaf curing is the final link in the production of flue-cured tobacco that determines the quality and yield. Advanced curing technology can fully reveal the excellent characteristics of mature tobacco leaves, increase production and income, and realize its use value. Although the domestic tobacco leaf curing technology has been greatly improved at this stage, there are still many problems. For example, (1) coal combustion is still the main source of heat supply, and the harmful gases discharged during the coal combustion process cause serious environmental pollution; The wet method not only causes high energy consumption loss during the curing process, but also discharges the aroma carried by the tobacco...

AI Technical Summary

Problems solved by technology

[0005] Although there are barns that use solar energy, air energy, and electric energy to bake tobacco leaves, there are still the following problems: (1) The existing solar-intensive barns directly heat the air. Although the temperature of the heating room has been increased, due to the The cost of heat storage is high, so the utilization rate of solar energy is low; (2) The heat pump heating method is adopted, and all the barns are heated by electric energy. In addition, the densely distributed barns are clustered, and the requirements for power and grid protection are high; (3) Electricity Due to the large total power of a single seat, the baking room needs to be equipped with a dedicated transformer, which puts a lot of pressure on the rural power grid. It needs to be developed with rural infrastructure and coordinated with the development trend of the national power grid, so the promotion cost is relatively high
