Description

A tobacco flue-cured room with dehumidification and cold air outdoor warming cycle

technical field

The invention relates to the technical field of a tobacco flue-curing room, more specifically, to a tobacco flue-curing room with dehumidification and cold air outdoor warming cycle.

Background technique

The flue-cured tobacco room is an indispensable basic equipment in the production of flue-cured tobacco. After the tobacco leaves are internally cured, they will show the unique color, aroma, taste and shape of flue-cured tobacco, and become high-quality raw materials that meet the needs of the cigarette industry. The basic principle is that after the tobacco leaves are heated, the water in the tobacco leaves is discharged, and the water is vaporized and then discharged out of the flue-curing room, so that the tobacco leaves are yellowed and dried.

The existing tobacco flue-cured room basically adopts the method of setting the dehumidification exhaust port of the flue-cured room to directly discharge the hot and humid air, so that the heat energy is discharged together, resulting in a large amount of waste of heat energy, and the utilization rate of heat energy is low. The cost of baking, and the hot air emitted will affect the surrounding environment of the tobacco curing room.

Contents of the invention

In order to overcome the above-mentioned defects in the prior art, the present invention provides a tobacco flue-curing room with dehumidification and cold air outdoor warming cycle.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

A flue-cured tobacco room with dehumidification and cold air outdoor warming cycle, comprising a circulation greenhouse located outside the flue-cured room, a heating device and an air conditioner located inside the flue-cured room; the circulated greenhouse communicates with the interior of the flue-cured room through an air vent; the air The regulator includes an indoor unit for cooling and dehumidification, and an outdoor unit connected to the indoor unit; the indoor unit and the outdoor unit are placed inside the tobacco curing room; the heating device is located at one end of the tobacco curing room, and the indoor unit and the outdoor unit are located at the other end of the tobacco curing room, and the indoor unit communicates with the circulation greenhouse.

The shell of the circulation greenhouse is made of heat-absorbing materials, such as glass or PC board (polycarbonate). Under normal circumstances, the outdoor temperature is 30-40°C, and the temperature in the circulation greenhouse can reach 60-70°C, so that the cold air blown out of the gas outlet of the indoor unit can be quickly converted into hot air.

By using the principle of the air conditioner (air conditioner) in the prior art, but different from the conventional installation method of the air conditioner, where the indoor unit is installed indoors and the outdoor unit is installed outdoors, the tobacco flue-curing room of the present invention integrates the indoor Both the machine and the outdoor unit are set inside the flue-cured room, and the cooling of the indoor unit is used to dehumidify. Specifically, the air inside the flue-cured room is drawn into the indoor unit and exchanges heat with the indoor unit, and the moisture in the air It condenses on the indoor unit, and at the same time, the cold air is sent from the indoor unit to the circulation greenhouse located outside the flue-curing room. The cold air absorbs heat in the circulation greenhouse and then returns to the inside of the flue-curing room, so that the air circulates between the interior of the flue-curing room and the circulation greenhouse. In addition, the heat generated by the outdoor unit is dissipated inside the flue-cured room, making full use of the heat energy of the outdoor unit. In this way, the moisture inside the flue-cured room can be removed, and the heat from the external environment can be used to flue-cure the tobacco, which greatly improves the utilization rate of heat energy, and the aroma of the flue-cured tobacco will not leak out of the flue-cured room. The tobacco flue-curing room dries the tobacco leaves to a golden or orange color, oil and aroma.

In addition, because both the indoor unit and the outdoor unit are equipped with circuit boards and other circuit components, but the internal temperature is relatively high during the flue-curing room, reaching 60-70 degrees, so it can be installed in the indoor unit and outdoor unit with circuit board equipment. A heat-insulating protective cover is set on the device, which can be made of existing high-temperature-resistant heat-insulating materials, and the shape of the protective cover matches the shape of devices with circuit boards such as indoor units and outdoor units, and only the air outlet is exposed In this way, equipment with circuit boards such as indoor units and outdoor units can be protected under the high temperature environment of 60-70 degrees in the flue-cured room, so that the service life is prolonged and the maintenance cost is reduced.

In order to allow the indoor unit and the outdoor unit to be better used in the flue-cured tobacco room and improve the condensation effect of the indoor unit, it is necessary to increase the pressure of the refrigerant during operation, and the copper pipes connected to the indoor unit and the outdoor unit need to bear more Therefore, the copper pipe adopts a thicker and thicker structure to prolong its service life and reduce maintenance costs.

Both ends of the condenser pipe are connected to the outdoor unit, and the refrigerant circulates between the condenser pipe and the outdoor unit, and is vaporized in the condenser pipe at the first fin to absorb heat from the surrounding air and the first fin , and at the same time, the first fins can rapidly exchange heat with the surrounding air, thereby enhancing the effect of cooling and dehumidification of the heat exchanger of the indoor unit.

Furthermore, the condensing pipe is a circuitous bent pipe structure, which can increase the heat exchange area, ensure the condensation of water vapor in the air, and improve the dehumidification effect.

In order to reduce the wind pressure loss inside the indoor unit and reduce the load of the exhaust fan, further, the first fins are provided with through holes.

In order to drain the condensed water in time and avoid the accumulation of condensed water, further, the shape of the water collection tank is funnel-shaped, and the lower end of the water collection tank is connected with the drain pipe.

In order to allow the cold air passing into the circulation greenhouse to be fully heated and warmed up, further, a cold air recovery device is provided in the circulation greenhouse, and the cold air recovery device includes multi-layer covers that are sequentially arranged from the inside to the outside and connected in sequence. The machine communicates with the innermost cover body, and the outermost cover body communicates with the interior of the circulation greenhouse.
