Description
Technical Field
The utility model relates to a flue-cured tobacco field, in particular to heating device is toasted in tobacco flue-curing house.
Background
Tobacco leaves are main projects for promoting the poverty alleviation of rural industries by governments at all levels in China, the tobacco leaf baking cost and quality are related to the economic benefit of tobacco growers, and the key for improving the tobacco leaf baking quality and reducing the baking cost lies in baking equipment and a baking method. For a long time, tobacco leaf baking equipment of tobacco growers is gradually changed into electric baking and biomass gasification combustion machines from an earthen coal furnace, the electric baking cost is high, and the profits of tobacco growers are reduced. The existing biomass combustion device has at least the following defects: (1) the burnt ash cannot be automatically removed, so that the potential safety hazard caused by the air passage blockage and tempering is easily caused; (2) the gasification combustion is incomplete, the heat energy benefit is not high, and substances such as tar which are not completely combusted can enter the heat supply pipeline and be coated on the inner wall of the heat supply pipeline, so that the baking effect and the tobacco leaf quality are influenced. According to statistics, 120 ten thousand seats of intensive tobacco curing houses built in China by 2017 are provided, wherein 99.9% of coal-fired tobacco curing houses are used, 350 ten thousand tons of coal are consumed in each year in baking, about 870 ten thousand tons of carbon dioxide, 21 ten thousand tons of sulfur dioxide, 3 ten thousand tons of nitrogen dioxide, 0.7 ten thousand tons of carbon monoxide (coal gas) and 3.5 ten thousand tons of dust are discharged in the combustion process, and a large amount of harmful gas is discharged to cause great pollution to the environment. Therefore, it is a problem to be solved to reduce the baking cost and environmental pollution.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tobacco flue-curing house toasts heating device, it adopts stoving heat pump set, utilizes the air energy to produce the heat energy circulation and toasts the tobacco leaf, can guarantee the tobacco leaf quality, is favorable to the environmental protection.
To achieve the above object, the embodiment of the present invention is: the utility model provides a tobacco flue-curing house toasts heating device, including stoving heat pump set and with the heat supply room of baking chamber intercommunication, stoving heat pump set and heat supply room intercommunication, the heat supply room top be provided with the backward flow room of baking chamber intercommunication, have the through-hole between backward flow room and the heat supply room, through-hole department is provided with the fan.
Preferably, the drying heat pump unit is mounted at the rear part of the heat supply chamber in an embedded manner.
Preferably, the drying heat pump unit is connected with a controller.
Preferably, the drying heat pump unit is a Wu tobacco drying heat pump unit.
The utility model has the advantages that:
(1) because the heating device is a tobacco drying heat pump unit, the tobacco leaf is dried by adopting heat energy generated by an air energy heat pump, the tobacco leaf drying device is clean and environment-friendly, and tar or harmful substances in fuel gas generated by gasification of biomass fuel or combustion of coal can be prevented from entering a tobacco curing room to influence the quality of flue-cured tobacco, thereby ensuring that the quality of the flue-cured tobacco leaf is improved.
(2) The heat supply room top is provided with the backward flow room, and the steam in the baking chamber gets into the backward flow room after, and the fan that the backward flow indoor setting was set up can blow into the heat supply room with the steam in the baking chamber in, then gets into the baking chamber again and toasts the tobacco leaf, so recycling, can reduce the energy consumption, toasts the cost.
(3) When the air energy heat pump dryer is used for baking tobacco leaves, the energy is saved, the operation is stable, automatic and accurate control can be realized, and the time and labor cost are greatly saved.
