の制御を行うには、除湿液の濃度を指示値として
いた。 Traditionally, wet dehumidifying liquid machines have been often used when dehumidifying air industrially, but these machines consist of a dehumidifying tower that brings the air to be treated into contact with a dehumidifying liquid to obtain dehumidified air, and a dehumidifying tower that produces dehumidified air. It usually consists of a regeneration tower that regenerates the dehumidifying liquid, which has been enriched in moisture by contacting the air to be treated, by contacting it with a stream of air in the presence of heat. In this case, it is necessary to appropriately control the degree of regeneration of the dehumidifying liquid in the regeneration tower, but in conventional devices, the only control factor is the amount of supply of the regeneration heat source. In order to perform this control, the concentration of the dehumidifying liquid was used as an instruction value.
しかし、除湿液の濃度を指示値として再生用熱
源の供給量を制御する方式では、制御の遅れが大

よつて、再生塔に熱の供給を停止した場合などで

を必要とすることになる。 However, with the method of controlling the supply amount of the regeneration heat source using the concentration of the dehumidifying liquid as the indicated value, there is a large delay in control, resulting in variations in the dehumidifying function of the dehumidifying tower and the inability to immediately follow changes in outside air conditions. I was hanging out. In particular, when the load is low, hunting often occurs and an excessively large heating heat source is required. For example, if the supply of heat to the regeneration tower is stopped due to excessive control, the regeneration tower will cool down, and in order to return to a steady state, excessive heat will be required to heat the regeneration tower again. You will need it.

に必設な熱量を制御する点にある。 For this purpose, a dehumidifying tower is used to obtain dehumidified air by bringing the air to be treated into contact with a dehumidifying liquid, and a dehumidifying liquid, which has come into contact with the air to be treated in the dehumidifying tower and has a high moisture content, is brought into contact with the dehumidifying liquid in the presence of heat. In a wet dehumidification device comprising a regeneration tower that regenerates air by bringing it into contact with an air flow, the present invention uses a variable air volume blower as a blower for blowing air to the regeneration tower, and also supplies heat for regeneration. A means for adjusting the amount of water is provided, and while the amount of water dehumidified by the dehumidification tower is continuously detected, the variable air volume blower and the heat supply means are controlled according to the amount of water. The gist of this control is to calculate the amount of moisture dehumidified in the dehumidification tower based on the humidity of the air before and after the gas-liquid contact in the dehumidification tower, as well as the detected value of the amount of air being sent, and to use this dehumidified moisture amount value for regeneration. The air volume required for regeneration in the tower is calculated, and the regeneration air volume is controlled by operating the variable air volume blower using the calculated value of the regeneration air volume, and the calculated value of the regeneration air volume and the outlet of the regeneration tower. The point is that the amount of heat required for regeneration is controlled by operating the heat supply means based on the air temperature.

Ru. The air dehumidified by this gas-liquid contact is sent to a load 7 such as a plant that requires dehumidified air. After the gas-liquid contact, the dehumidifying liquid (hereinafter referred to as diluted dehumidifying liquid because it has been diluted by moisture impregnation) enters the dehumidifying side tank 8.
The liquid is circulated from the dehumidification tank 8 to the dehumidification tower 1 and the regeneration tower 2 by the dehumidification side pump 9.
A heat exchanger 10 for exchanging heat with cold water is provided in the pipe leading to the liquid dispersion device 5, and the dehumidified air is cooled to a predetermined dehumidified air temperature before entering the dehumidifying tower 1.

At this time, in this embodiment, heat for regeneration is applied to the diluted dehumidifying liquid before entering the liquid spraying device 13. That is, heat is applied to the diluted dehumidifying liquid by passing through the heat exchanger 15 that uses water vapor as a heat source. Due to this heating, the moisture in the liquid is released to the outside air and the liquid is regenerated.
This regenerated liquid (regenerated liquid) is stored in the regeneration side tank 1.

２２に介装してある。 In the apparatus of the present invention, a variable air volume blower is used as the regeneration side blower 12 in such a regeneration type continuous wet dehumidification apparatus. For example, the amount of air blown is controlled by controlling the rotational speed of the blower motor or controlling the pitch angle of the blower blades. Most preferably, the rotation speed of the motor is controlled by an inverter unit 20. A means for controlling the amount of heat supplied from the regeneration heat source is provided. In the example of FIG. 1, this is a control valve 21 that controls the amount of steam supplied to the heat exchanger 15, and is interposed in a steam line 22.

信号ｄも入力される。 Then, the amount of water that is continuously dehumidified in the dehumidification tower 1 is continuously detected. The amount of dehumidified moisture is detected by an air flow meter 23 that measures the amount of outside air blown to the dehumidifying tower 1, a dew point thermometer 24 that detects the dew point temperature of the air before it comes into contact with gas and liquid in the dehumidifying tower 1, and a dehumidifying body 1. This is performed based on the respective measurement values of the dew point thermometer 25 that detects the dew point temperature after the gas-liquid contact. More specifically, detection signals a, b, and c from these measuring instruments are input to the computer 27 and calculated there. Further, a detection signal d from a temperature detector 26 that detects the temperature of the exhaust gas after the gas-liquid contact in the regeneration tower 1 is also input to the computer 27 .

A control signal B is output to an inverter unit 20 that controls the rotational speed of the regeneration tower 1, and the air flow rate of the regeneration tower 1 is controlled by feed forward. As a result, the concentration of the recycled liquid is maintained constant, and at the same time, the computer 27 calculates the amount of regenerated heat source corresponding to the amount of regenerated air blown from the input signal d of the outlet temperature detector 26 of the regeneration tower 1, and controls the amount. A control signal B is output to the valve 21 to control the amount of heat (amount of water vapor) required for regeneration by feedback. This enables power-saving operation of the regenerative blower and energy-saving operation of the regenerative heat exchanger commensurate with the dehumidifying load, while at the same time compensating for fluctuations in the concentration of the dehumidifying liquid and ensuring stable operation of the entire device. .

A dehumidifying tower for obtaining dehumidified air by bringing the air to be treated into contact with a dehumidifying liquid, and a dehumidifying liquid whose moisture content has increased due to contact with the air to be treated in the dehumidifying tower in the presence of heat. In a wet dehumidification device that consists of a regeneration tower that regenerates air by contacting it with a flow of air, a variable air volume blower is used as a blower to send air to the regeneration tower, and the amount of heat supplied for regeneration is adjusted. In addition, the amount of moisture to be dehumidified in the dehumidification tower is calculated from the detected value of the humidity of the air before and after the gas-liquid contact in the dehumidification tower and the amount of air being sent, and this dehumidified moisture amount value is used to calculate the amount of moisture to be dehumidified. Calculate the air volume required for regeneration in the regeneration tower, use the calculated value of the regeneration air volume to control the regeneration air volume by operating the variable air volume blower, and at the same time, combine the calculated value of the regeneration air volume with the regeneration tower. A method for controlling a wet dehumidifier, comprising: controlling the amount of heat required for regeneration by operating the heat supply means based on the outlet air temperature.
