technical field

The utility model relates to a dehumidification device used in the tobacco leaf curing process, in particular to a device capable of both dehumidification and heat energy recycling.

technical background

In the process of tobacco leaf curing, the traditional method of drying and dehumidification is to introduce the cold and dry air outside the curing room into the curing room, and at the same time discharge the wet and hot air in the curing room. Through long-term gas exchange and process control, it can achieve The purpose of drying fresh tobacco leaves into dry tobacco leaves. During the gas exchange process inside and outside the curing barn, a large amount of heat energy and tobacco leaf volatiles are discharged. The loss of heat energy causes a great waste of energy, and the discharge of tobacco leaf volatiles causes environmental pollution and the decline of tobacco leaf quality. In this regard, some people in the industry are also trying to find a solution, but due to design defects, various dehumidification devices or operations are cumbersome, or the equipment is complex, and the input and output are out of proportion, it is difficult to generate economic benefits, and it is difficult to promote and implement in the end.

In order to solve the above-mentioned technical problems, the utility model is a dehumidification heat recovery and utilization device for tobacco leaf baking, which includes a dehumidifier, a heater, a dehumidification fan and a compressor, and an integrally formed shell is provided. The front and rear sections are respectively provided with a dehumidification air inlet and a dehumidification air outlet, and the bottom of the housing is provided with a drain port; the dehumidifier, heater and dehumidification fan are movable in the housing, and the dehumidifier is arranged at the dehumidification air inlet end. The dehumidifier is arranged at the outlet end of the dehumidified gas flow, and the compressor is arranged outside the housing; the dehumidifier, the heater and the compressor are connected through pipelines, and the heat exchange is carried out with a heat transfer medium.

As an improvement, the outer surface of the shell of the utility model is provided with a thermal insulation layer or the shell is made of thermal insulation material; the dehumidification fan is arranged between the heater and the dehumidification air outlet.

The shell of the utility model is integrally formed, which not only forms a closed dehumidification air duct, but also serves as an installation carrier for the various components. The integrated design can reduce the difficulty of installation and greatly reduce the installation cost; the dehumidifier, heater and The dehumidification fan can be connected and fixed in the dehumidification air duct formed by the shell with bolts, which is easy to disassemble, repair and replace, and makes the work simple and easy; the dehumidification fan is set between the heater and the dehumidification air outlet, which can maximize the The dehumidified airflow is forced to flow from front to back; the outside of the shell is provided with an insulation layer or the shell is directly made of concentrated materials to reduce heat dissipation through the shell. The dehumidifier, heater and compressor of the utility model are connected through pipelines, and heat exchange is carried out through the heat transfer medium. Water and gas with a lower temperature, the water is discharged from the drain at the bottom of the shell, the gas is heated by the heater and then returned to the barn to cure the tobacco leaves. In this process, the tobacco leaf curing process is completed The airtight shell is integrally formed to ensure that there is no gas exchange inside and outside the barn, and there is no loss of heat energy. It can save more than 30% of coal burning, and the volatiles of tobacco leaves will not be discharged into the air. There is no problem of environmental pollution, and the quality of tobacco leaves can be guaranteed, energy saving and environmental protection, and high efficiency.

Beneficial effects of the utility model: due to the use of the above-mentioned structure, the utility model has no gas exchange inside and outside the barn during the drying and dehumidification process of the tobacco leaves, no loss of heat energy, high thermal efficiency, no volatiles of the tobacco leaves are discharged into the air, and no environment pollution, and the quality of the cured tobacco leaves is good; the device is reasonable in design, easy to manufacture and install, easy to operate, easy to popularize, and has good social and economic benefits.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

The utility model is a dehumidification heat recovery and utilization device for tobacco leaf baking, which includes a dehumidifier 5, a heater 4, a dehumidification fan 3 and a compressor 7, and an integrally formed shell 1 is arranged. In front of the shell 1, The rear section is respectively provided with a dehumidification air inlet 6 and a dehumidification air outlet 2, and the bottom of the housing 1 is provided with a drain 9; It is arranged at the end of the dehumidification air inlet 6, the heater 4 is arranged at the end of the dehumidification air outlet 2, and the compressor 7 is arranged outside the shell 1; the dehumidifier 5, the heater 4 and the compressor 7 are connected by pipelines Connected to exchange heat with heat transfer medium.

As an improvement, the housing 1 of the present invention is provided with an insulation layer or the housing 1 is made of insulation material; the dehumidification fan 3 is arranged between the heater 4 and the dehumidification air outlet 2 .

Embodiment 1: The dehumidification heat recycling device of the utility model, the housing 1 is integrally formed with metal materials and an insulation layer is arranged on the outside, installed on the roof of the barn, the dehumidification air inlet 6 and the dehumidification air outlet 2 are connected with the oven The rooms are connected, and the connection is sealed and fixed. The dehumidifier 5, the heater 4 and the dehumidification fan 3 are fixed in the housing 1 with bolts, and the compressor 7 is fixed outside the housing 1 with bolts. During the dehumidification work, the dehumidification fan 3 forces the hot and humid gas to pass through the dehumidification air inlet 6 and enter the dehumidification air duct 8, and reach a certain wind speed. The water is discharged through the drain port 9, and the dried gas after cooling and dehydration is heated again by the heater 4, and then returns to the barn through the dehumidification air outlet 2. In the dehumidification process, the compressor 7 compresses the heat transfer medium, expands and absorbs heat in the dehumidifier 5 through the medium, cools and dehumidifies the hot and humid gas, dissipates heat in the heater 4, and reheats the dry gas. During this energy transfer process, there is no heat exchange with the outside of the barn.

The above are only some implementations of the present utility model, and the housing can also be directly made of heat-insulating materials. As long as the above-mentioned structures are used, they should all fall within the scope of protection of the present utility model.
