Description

[Detailed Description of the Invention] This invention is designed to be installed in manufacturing plants, storage rooms, etc. for the purpose of preventing rust or corrosion of industrial products, etc., or preventing deterioration or quality control of foods, chemicals, etc. It consists of a drum-shaped rotor made of asbestos impregnated with a moisture absorbent and forming a honeycomb-shaped air passageway in the axial direction, a motor that rotates the rotor around its central axis, and an air passageway in the rotor. a fixed sector that divides the air into a treated air passageway and a regenerated air passageway, a treated air blower that passes the treated air through the treated air passageway, and a regenerated air blower that passes the regenerated air through the regenerated air passageway. Regarding improvements to the machine.

Conventionally, this type of dehumidifier has had a configuration as shown in FIG. 1, for example.

What is indicated by the reference numeral 1 in the figure is the rotor.

The rotor 1 is formed into a drum shape and is supported by its horizontal central axis 1a.

A honeycomb-shaped air passage 1b is formed around and parallel to the central axis 1a.

The air passage 1b is made of non-combustible paper, plastic, etc.
Lithium chloride (LiCl) is made from asbestos, etc.
), etc., and absorbs moisture from the air passing through the air passage 1b.

A belt 2 is stretched around the outer periphery of the rotor 1.

The other side of the belt 2 is hung on the pulley 4 of the motor 3,
The rotor 1 is stably rotated around its central axis 1a.

The speed is about 8 to 18 rph. Fixed sectors 5 are installed on both sides of the roller 1 in the axial direction, and divide the air passage 1b of the rotor 1 into a processing air passage α and a regeneration air passage β.

The classification is for treated air passage α between 2 and 3:
The ratio of the regeneration air passage β is approximately 1.

Dry air is produced in one of the processing air passageways α, and humid processing air is sent there by the processing air blower 6.

Processing air is sent in the direction of arrow α in the figure.

Since a filter 11 is installed on the inlet side of the processed air passage α, the humid processed air sent by the blower 6 passes through the filter 7 and enters the post-processed air passage α.

Moisture is absorbed in the treated air passage α, and the dry air is sent out from the outlet side to the dehumidifying chamber.

On the other hand, absorbed moisture is discharged from the regeneration air passage β, and regeneration air is sent there by the regeneration air blower 8.

In conventional dehumidifiers, the regeneration air is sent in the direction of arrow b in the figure, opposite to the treated air.

A heater 10 is installed together with a filter 9 on the inlet side of the regeneration air passage β, and the regeneration air sent by the blower 8 passes through the filter 9 and enters the post-heater 10.
There, the heated regeneration air is heated and enters the regeneration air passageway β.As mentioned above, since the rotor 1 is rotated by the motor 3, the heated regeneration air sent to the regeneration air passageway β is heated through the treated air passageway α. The water absorbed on the side is taken away and is discharged to the outside from the outlet side.

Therefore, the rotor 1 recovers the moisture absorption effect again and exhibits the dehumidification effect on the treated air passage α side.

However, in the conventional dehumidifier described above, heated regeneration air is sent into the rotor 1, so it is impossible to dehumidify air that may contain flammable gas.

Additionally, since a heater is used to generate the heated regeneration air, there is also the drawback of high power consumption.

Furthermore, in conventional dehumidifiers, since the flow directions of the treated air and the regeneration air are opposite, there is a drawback that a vortex is generated near the boundary, reducing the dehumidification effect.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate these conventional drawbacks and provide a dehumidifier that has a much higher dehumidification effect than conventional dehumidifiers.

In the dehumidifier according to the present invention, a treated air blower and a regenerated air blower are installed so that the direction of the treated air passing through the air passage is the same as the direction of the regenerated air, and the air blower is installed on the inlet side of the air passage. The infrared ray generator is provided with an infrared ray generator that irradiates the regeneration air passage from the inlet side with a taper that becomes narrower as it approaches the outlet side.

The present invention will be explained below based on an embodiment of the present invention shown in FIG.

In the dehumidifier according to the present invention, the treated air blower is first set so that the direction of the treated air passing through the air passage 1b (direction of arrow a in the figure) and the direction of regenerated air (direction of arrow b in the figure) are the same. 6 and a regeneration air blower 8 are installed.

Furthermore, in the conventional dehumidifier, the air passage 1b was made to have the same size from the inlet side to the outlet side as shown in FIG. 3, whereas in the dehumidifier according to the present invention, for example, As shown in FIG. 4, the air passage 1b is tapered by about 1 to 3 degrees so that it becomes narrower from the inlet side to the outlet side.

As mentioned above, the air passage b1 is made of asbestos, non-combustible paper, hard vinyl chloride, etc., for example, by pasting a corrugated board on a flat plate, winding it into a drum shape to create a rotor, and soaking it in water. , then impregnated with lithium chloride and dried in a drying oven for several hours.

Furthermore, in the dehumidifier according to the present invention, an infrared generator 11 is used in place of the conventional heater 10.

This infrared ray generator 11 irradiates the regeneration air passage β from its entrance side through a glass cube 12.

The other parts are the same as those of the conventional dehumidifier, and the same reference numerals used for the parts corresponding to FIG. 1 are also used in FIG. 2, and the explanation thereof will be omitted.

Therefore, according to the present invention, since an infrared generator using an infrared lamp or the like is used instead of a conventional heater using a heating wire, the power consumption is significantly reduced compared to the conventional one, and the dehumidifier according to the present invention Since it became possible to use glass gloves, it became possible to dehumidify air containing flammable gases as an explosion-proof type.

Furthermore, by using an infrared generator, the rotor can be directly heated and the rotor can be efficiently dried.

Further, since the air passage is tapered so that it becomes narrower as it approaches the exit side, the infrared ray receiving surface increases, and absorbed moisture can be efficiently removed.

In addition, by tapering the air passage, the speed of air passing through the rotor can be changed and the dehumidification effect can be enhanced.

Furthermore, since the direction of flow of the regeneration air and the processing air is the same, no vortex is generated at the boundary between them, and from this point of view as well, the dehumidification effect can be made extremely efficient.
