Intensive type curing barn capable of realizing afterheat recycling and zero pollutant emission

Abstract

The invention discloses an intensive type curing barn capable of realizing afterheat recycling and zero pollutant emission. The curing barn comprises a barn body, an air source heat pump, an afterheat recycling device and a circulating fan, wherein the barn body comprises a heating room and a tobacco placement room; the air source heat pump comprises an outdoor main machine, a phase change heat storage type condenser and a connecting pipeline; and the indoor main machine comprises a compressor, an evaporator and a capillary tube. The air source heat pump, used as heating equipment, has zero pollutant emission in the use process, and is automatically controlled in the whole process, so that labor intensity in tobacco curing is greatly lowered; by virtue of the frequency conversion type compressor, the heat load can be flexibly adjusted; by virtue of the phase change heat storage type condenser, the hot air temperature output is stable, so that temperature fluctuation in the curing barn is low; meanwhile, by virtue of a heat storage material, the size of a heat exchanger can be reduced to a relatively high extent; the afterheat recycling device can effectively utilize heat dissipation loss in a dehumidifying process; and by virtue of a heat preservation and insulation layer on the ground below the tobacco placement room, the ground heat dissipation loss can be greatly reduced.

Description

technical field [0001] The invention relates to an intensive barn with waste heat recovery and zero emission of pollution, in particular to a barn suitable for tobacco leaf roasting. Background technique [0002] At present, most of the heating equipment for flue-cured tobacco curing rooms are processed and manufactured according to the State Tobacco Office [2009] No. 418. It is a typical hand-fired furnace. Coal, the disadvantages of this kind of furnace are: low combustion efficiency, high fuel consumption, and a large amount of pollutants such as SO 2 , solid waste, dust, etc.; when working, there must be a special person to add coal to the furnace, which is laborious and laborious. If the coal is not added in time, it will cause large fluctuations in the temperature of the tobacco chamber, which will seriously affect the quality of tobacco leaf curing. The use of air source heat pump as the heating equipment for tobacco leaf curing can realize the full automation of tob...
