Abstract

PROBLEM TO BE SOLVED: To uniformly heat a regeneration air for a rotary dehumidifying material and thereby efficiently remove moisture from the rotary dehumidifying material by dividing the regeneration air to be sent in from the opening of a case into a plurality of routes respectively having varying thermal quantities for heating using a divider plate and adjusting an amount of blast according to the open area of both routes. SOLUTION: The opening part 3 of a case 2 into which a regeneration air is sent, is divided into plural routes using a divider plate 4. That is, these routes are a route into which the regeneration air B is introduced from the lower side of the divider plate 4 to be guided out from the slit of a blow-off cover 6 and a route into which the regeneration air C is introduced from the upper side of the divider plate 4 to be guided to a heating part 9 by a baffle 5 and further guided out of the open hole 7 of the blow-off cover 6. In this case, the regeneration airs B, C are sent to a rotary dehumidifying material in such a state that the amount of a blast of the regeneration air C in the route through the heating part 9 is relatively increased. In addition, the rotary dehumidifying material is first heated and regenerated by the regeneration air B passing through the heating part 9 and then is thermally regenerated in succession by the regeneration air C not passing through the heating part 9.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for heating regenerated air to a rotary dehumidifier in a dehumidifier having a rotary dehumidifier.

[0002]

2. Description of the Related Art First, the structure of a dehumidifier provided with a rotary dehumidifier using a conventional regenerative air heating device for a rotary dehumidifier will be described.

FIG. 8 is an explanatory diagram of the entire structure of a dehumidifier. The dehumidifying rotor 31 has a zeolite (hygroscopic agent) supported on the surface or inside of a honeycomb rotor in which a single-wave molded body is wound on a flat sheet. The zeolite has no deliquescent phenomenon, and has a crystalline and stable pore structure. With less deterioration due to moisture adsorption and stable moisture absorption for a long time.

The air 32 to be dehumidified is sucked by a dehumidifying fan 45, and coarse dust is removed by a filter 33.
And cools the regeneration air inside the warm and moist condenser, as described later, to condense moisture in the regeneration air. The dehumidified air 32 that has passed through the condenser 34 passes through the dehumidifying rotor 31 and is absorbed by a desiccant to become dry air 36. The heat is recovered by the heat recovery heat exchanger 35 and then released into the room.

In order to regenerate the moisture absorbent of the dehumidifying rotor 31 which has absorbed moisture, the regenerating air is heated to 200 ° C. to 250 ° C. by the heating unit 9 which is a regenerating heater, and then blown to the dehumidifying rotor 31 by the regenerating fan 38. . The heated regeneration air receives moisture from the desiccant of the dehumidifying rotor 31,
It becomes warm and moist air, is cooled by the condenser 34, and condenses and discharges moisture. Condensed water 39 is a water receiving tank 40
It is led to. The water receiving tank 40 is provided with a float switch (not shown) for detecting the water level. When a predetermined water level is detected, the water pump 41 provided is operated, and the dew condensation water 39 is supplied to the water storage tank 42 via the water pumping tube 48. To store.

The dehumidifying rotor 31 is rotated by a driving motor (not shown), and the dehumidifying section 46 through which the air 32 to be dehumidified passes and the regenerating section 47 through which the heated hot air passes gradually rotate. Even if it absorbs moisture, it is also regenerated and can be used continuously.

Since the heated hot air passes through the dehumidifying rotor 31 and rotates little by little, the dehumidifying rotor 31 is warmed. Since the dehumidified air 32 passes here, the heat recovery heat exchanger 35 is heated by the dried air 36 warmed after passing.
To recover heat. The regeneration air after the dew condensation water 39 is discharged from the condenser 34 passes through the heat recovery heat exchanger 35, and the power of the heating unit 9 as the regeneration heater can be saved by the amount of the heated air. As described above, the regeneration air forms a closed circuit and is used repeatedly.

[0008]

With the above-mentioned conventional structure, the heating device does not provide a uniform hot air temperature with respect to the dehumidifying rotor during heating. Water could not be efficiently extracted.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the apparatus for heating regenerative air to a rotary dehumidifier according to the present invention blows heated regenerative air onto a rotary dehumidifier that has absorbed moisture.
In the apparatus for extracting moisture and regenerating the rotary dehumidifier, the regenerated air fed from the opening of the case is divided into a first path having a large heating amount and a second path having a small heating amount at the opening of the case. The air flow rate is adjusted according to the opening area of the first and second paths at the opening of the case at the opening of the case.

The first and second paths are formed by a partition plate for the regenerated air fed into the case from the opening on the side of the case of the regenerative air heating device, and the direction of the air is changed by approximately 90 degrees. And heating and discharging at a heating section on the downstream side of the split plate, wherein air blowing to the heating section in the first path having a large heating amount is obstructed provided on the case side of the first path. The plate is used to uniformly adjust the air flow of the heating unit.

The amount of air blown in the first path having a large amount of heating is adjusted by adjusting the amount of air blown in the second path having a small amount of heating by the area of the outlet of the blowout cover. It is made larger and located upstream in the rotation direction of the dehumidifying rotor.

Further, the air outlet of the second path is formed in a slit shape.

Further, the shape of the air outlet of the first and second paths is adjusted by framing holes to adjust the air flow.

According to the present invention, moisture is taken out from the rotary dehumidifier that has absorbed the regenerated air of the hot air that has passed through the first path having a large amount of heating, and the rotary dehumidifier is rotated. The hot air passes through, and the portion of the rotary dehumidifying material that has been warmed by the residual heat is blown by the regenerated air that has passed through the second path with a small amount of heating, and further takes out and regenerates the moisture, and the first and the second The air flow rate of each path can be adjusted according to the area of the outlet of each path of the blow-out cover by a dividing plate for dividing the area of the opening of the case.

The upstream portion of the case near the opening of the case into which the regenerating air is fed has the opening of the case narrowed by a dividing plate to provide a second path for the regenerating air having a small heating amount. The opening is widened by a dividing plate to form a first path having a large heating amount. Since the regenerative air changes the direction of air blowing by approximately 90 degrees, the amount of air blown in the first path, which is main, is larger than the amount of air blown in the second path, which is sub.

In the first path, the opening of the case is widened by the dividing plate, so that the air to the heating section is uniformly adjusted by the baffle plate and sent to remove heat from the heating section to obtain a uniform temperature. , Can be sent to the regeneration unit of the dehumidifying rotor.
