Description

A drying room with one-time utilization of moisture-discharging heat energy

technical field

The utility model relates to the heat preservation of a drying room, more specifically, relates to a drying room which utilizes heat energy of dehumidification for heat preservation.

Background technique

In the traditional drying room, when drying and dehumidifying, the hot and humid air is often discharged directly, or recycled by a total heat exchanger, and the utilization effect is poor.

The heat loss in the drying room is objective. If the moisture content of the material to be dried is low, the heat loss in the drying room itself can account for more than 80% of the total drying heat. Therefore, the traditional drying room has the defects of large heat loss and low heat utilization rate.

Utility model content

The purpose of this utility model is to overcome the above-mentioned defects in the prior art, and provide a method of using the discarded dehumidified hot air to keep the drying room warm, which can greatly reduce the heat inside the drying room from diffusing to the outside, so as to save energy and heat utilization It is a drying room with a high efficiency of dehumidification and heat energy utilization.

In order to achieve the above object, the technical scheme provided by the utility model is as follows:

Provide a drying room for one-time utilization of moisture-discharging heat energy, including the outer wall of the drying room, the inner tank of the drying room installed in the outer wall of the drying room, the heat source and the circulating fan installed in the inner tank of the drying room, and communicated with the inner tank of the drying room The new air inlet pipe, the fresh air valve installed on the fresh air pipe, the top of the drying room liner is provided with the first row of wet air outlets connected with the inside of the drying room liner, the outer wall of the drying room and the drying room An insulating interlayer for the flow of hot and humid air is formed between the outer walls of the liner in the room, and the outer wall of the drying room is provided with a second row of humid air outlets connected with the insulating interlayer.

As a preference, in the above technical solution, the second humidity exhaust outlet is arranged at the lower part of the outer wall of the drying room.

As a preference, in the above technical solution, a dehumidification blower is installed in the first dehumidification outlet.

As a preference, in the above technical solution, the outer wall of the drying room is a hollow structure.

Compared with the prior art, the beneficial effect of the utility model is that: by forming an insulating interlayer between the outer wall of the drying room and the inner tank of the drying room for the flow of hot and humid air, when baking, the heat source and the circulating fan are started, and the temperature rises. The moisture in the material to be baked evaporates, and when the humidity in the drying room rises to the humidity setting value, the fresh air valve opens, the dehumidification fan starts, and the hot humid air enters the insulation interlayer through the first dehumidification outlet. When the hot and humid air fills the insulation interlayer, the excess hot and humid air is discharged from the second row of humid air outlets, so that the discarded hot and humid air is used to insulate the drying room. The temperature difference between the hot and humid air and the inner tank of the drying room is small. The temperature difference is the driving force of heat transfer, and the small temperature difference can greatly reduce the heat diffusion from the inside of the drying room to the outside, so as to save energy.

A drying room for one-time utilization of moisture-discharging heat energy described in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

detailed description

The following is a best example of a drying room for one-time utilization of moisture-discharging heat energy described in the utility model, and does not limit the scope of protection of the utility model.

Please refer to Fig. 1, which shows a drying room for one-time use of moisture-discharging heat energy, including a drying room outer wall 1, a drying room liner 2 installed in the drying room outer wall 1, and a drying room liner 2 installed in the drying room The heat source 3 and the circulating fan 4, the fresh air duct 5 connected with the drying room liner 2, the fresh air valve 6 installed on the fresh air duct 5, the top of the drying room liner 2 is provided with a drying The first row of wet tuyeres 7 connected to the inside of the inner liner 2, the outer wall 1 of the drying room and the outer wall of the inner liner 2 of the drying room form an insulating interlayer 8 for the flow of hot and humid air, and the outer wall 1 of the drying room is provided with the insulating interlayer The second row of wet tuyere 9 connected by 8 phases. When baking, the heat source 3 and the circulation fan 4 are started, the temperature rises, and the water in the baked material evaporates. When the humidity in the drying room rises to the humidity setting value, the fresh air valve 6 is opened, the dehumidification blower 10 starts, and the hot humid air enters the insulation interlayer 8 through the first dehumidification port 7 . When the hot and humid air fills the insulation interlayer 8, the excess hot and humid air is discharged from the second row of humid air outlets 9, so that the discarded hot air for dehumidification is used to insulate the drying room, and the temperature difference between the hot air for dehumidification and the inner tank 2 Small, because the temperature difference is the driving force of heat transfer, the temperature difference is small, which can greatly reduce the heat diffusion from the inside of the drying room to the outside, and achieve the purpose of saving energy.

Preferably, in this embodiment, the second humid air outlet 9 is arranged on the lower part of the outer wall 1 of the drying room, making full use of the hot and humid air to rise and keep warm, the lower temperature air sinks, and finally discharged from the second humid air outlet 9 It is moist air with lower temperature.

Preferably, in this embodiment, the first humidity exhaust outlet 7 is equipped with a moisture exhaust fan 10 , and the humid and hot air in the drying room liner 2 is discharged into the insulation interlayer 8 through the moisture exhaust fan 10 .

Preferably, in this embodiment, the outer wall 1 of the drying room is a hollow structure, which can further improve the heat preservation effect of the drying room.

Principle of the present utility model is as follows:

Ti≈Tm>To.

In the formula; Ti represents the temperature in the inner tank of the middle drying room;

Tm represents the temperature in the middle insulation interlayer;

To represents the temperature outside the outer wall of the middle drying room.

Since the temperature difference is the driving force for heat transfer, by setting the insulation interlayer 8, Tm≈Ti, so the amount of heat dissipation through the oven liner into the insulation interlayer 8 is very small, that is, the hot and humid air discharged from the oven liner 2 has insulation Effect: Tm>To, so the thermal insulation interlayer 8 part dissipates more heat to the outside of the drying room, and the heat lost by the thermal insulation interlayer 8 part of the drying room is continuously replenished by the hot and humid air discharged from the inner tank 2 of the drying room.

The above-mentioned embodiment is a preferred implementation mode of the present utility model, but the implementation mode of the present utility model is not limited by the above-mentioned embodiment, and any other changes, modifications and substitutions made without departing from the spirit and principle of the present utility model , combination, and simplification, all should be equivalent replacement methods, and are all included in the protection scope of the present utility model.
