Abstract

The invention discloses a multi-heat-source tobacco drying system which comprises a multi-heat-source heating device, a heat storage water tank and a drying room. The multi-heat-source heating device comprises a solar heat collector and an air source heat pump which are arranged in parallel, the one or more heat storage water tanks are connected with the multi-heat-source heating device through heat preservation pipelines, and energy storage water in the heat storage water tanks is heated through the multi-heat-source heating device; heat dissipation coil pipes and fans are arranged in the one or more drying rooms, the heat dissipation coil pipes are connected with the heat storage water tank through heat preservation pipelines, heat is released through energy storage water introduced into the heat storage water tank, the fans are used for driving air in the drying rooms to pass through the heat dissipation coil pipes, and water pumps for driving the energy storage water to circulate are arranged on the heat preservation pipelines. Solar energy can be fully used for drying operation, the air source heat pump is used as a supplementary heat source when the solar energy is insufficient, and the technical problem that in the prior art, solar energy is used as a heat source for drying operation, and the drying operation cannot be continuous due to the influence of sunshine duration is solved.

Description

technical field

[0001] The invention relates to the technical field of tobacco drying, in particular to a multi-heat source tobacco drying system. Background technique

[0002] my country is the country with the largest output of flue-cured tobacco in the world. At present, there are 1.2 million intensive curing barns in the country, most of which use coal-fired barns.

[0003] Coal-fired barns mostly use loose coal-fired hot air stoves, with an annual coal consumption of about 3.5 million tons, and the combustion process is unstable and the temperature rises unevenly, which is not conducive to the precise control of the flue-cured process and affects the quality of the tobacco leaves after curing. At the same time, the high ineffective energy consumption of the coal-fired barn leads to waste of fuel, and the emission of a large amount of pollutants such as SO2, NOx and solid particles causes environmental pollution.

[0004] With the development of modern tobacco agricultu...
