法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for switching a dehumidification tower for dehumidification and regeneration in a dehumidification apparatus that removes moisture from gas to obtain dry gas.

タイマーなどで一定時間ごとにおこなっている。(Prior art) Generally, in a dehumidifying device for obtaining dry air or other dry gas, one of the dehumidifying towers alternately selected from a pair of dehumidifying towers filled with a desiccant such as silica gel or activated alumina is used to Gas dehumidifiers are widely used in which the desiccant is heated and then cooled and regenerated in the other dehumidifying tower. The switching of the dehumidification tower for dehumidification and regeneration in this gas dehumidification equipment is as follows:
This is done at regular intervals using a timer.

める原因にもなっていた。'However, the gas to be dried is normally compressed by a compressor, water-cooled, and then supplied to a dehumidifier after being cooled and dehumidified by a type of aftercooler. The dew point of the drying gas fluctuates. For this reason, the switching time of the dehumidification tower is determined so that dry gas with a specified dew point can be obtained even after dehumidifying the gas to be dried with a high dew point for a specified period of time. The desiccant subjected to this process is heated more than necessary during regeneration with a small amount of adsorbed moisture, which is not desirable from the viewpoint of energy saving. Furthermore, the amount of drying gas used generally decreases at night or during lunch breaks, and the flow rate of the gas to be dried passing through the dehumidification tower decreases accordingly, and the amount of moisture adsorbed by the desiccant during this time is small.
The reason why the desiccant is regenerated at regular intervals, regardless of the actual amount of moisture absorbed by the desiccant or the flow rate of the dehumidifying process of the gas to be dried, is to heat the desiccant frequently when the amount of moisture absorbed is small. In this respect, too, a large amount of energy is wasted, and the deterioration of the desiccant is accelerated.

ある。(Problem to be Solved by the Invention) However, in the above switching method, the air humidity is detected at the piping exiting the adsorption tower or at one point in the desiccant layer of the adsorption tower. It is not possible to accurately determine when the desiccant reaches the breakthrough point, and incompletely dehumidified gas with a dew point above the specified dew point may be supplied to the user, or before the entire amount of desiccant is effectively used for moisture adsorption. There is a risk that the switching command will be issued and the purpose of reducing the number of times the desiccant is regenerated will not be achieved.

During dehumidification, almost all of the adsorption capacity of the desiccant is effectively utilized, reducing the number of times the desiccant is regenerated and ensuring that the drying gas is kept at a temperature below the specified dew point. It is an object of the present invention to provide a method for switching a dehumidification tower in a gas dehumidification device that can be obtained.

In a gas dehumidifier that regenerates the desiccant by heating and cooling the desiccant in the other dehumidifying tower, the dew point of the gas flowing through the desiccant layer of the dehumidifying tower during dehumidification is set at multiple points separated in the gas flow direction. The gas flowing through the outlet end of the desiccant layer reaches the set dew point based on the time difference and the distance between the measurement positions when the gas dew point rises at each measurement position and reaches the predetermined set dew point. This is a method for switching a dehumidifying tower in a gas dehumidifier, characterized in that a time point is calculated and the dehumidifying tower is switched before this time point.

維持されるのである。(Function) In the dehumidification tower switching method of the present invention, the dew point of the gas flowing through the desiccant layer of the dehumidification tower during dehumidification is measured at a plurality of positions spaced apart in the gas flow direction. The moving speed of the desiccant adsorption layer that is effective in maintaining the gas dew point below the set dew point can be determined from the time difference when the gas rises and reaches a predetermined set dew point and the distance between the dew point measurement positions. From this moving speed and the gas dew point measurement position, it is possible to accurately calculate the point in time when the gas dew point reaches the set dew point at the outlet end of the desiccant layer. By switching the dehumidifying tower that performs dehumidification and regeneration at this point or a short time before this point, the dehumidifying tower can be switched while effectively using almost 100% of the desiccant adsorption capacity. In addition, the gas dew point is also maintained below the set dew point.

計測演算装置１６により下記の演算をおこなう。First, compressed air, which is the gas to be dried, flows in from the gas to be dried 6, passes through the four-way valve 8, the dehumidification tower 2, and the four-way valve 9, and is supplied to the user side from the dry gas output lower. In the dehumidification tower 3, a built-in electric heater heats the desiccant 5 for a predetermined period of time (for example, 4 hours), and then a portion of the dry air from the dehumidification tower 2 is passed through the flow rate control valve 10 and the four-way valve 8 to the dehumidification tower 3. through the four-way valve 9, the on-off valve 11, and the outlet 12.
The desiccant is cooled for a predetermined period of time (for example, 4
time) to complete regeneration, close the on-off valve 11, and wait. On the other hand, in the dehumidification tower 2, dew point meters 14 and 15
The dew point of the circulating gas is detected by A, as shown in Figure 2.

is given from the measurement calculation device 16 to the main control device 17, and the main control device 17 receives the time t. The pneumatic drive unit 18 then switches the four-way valve 8.9 to the state shown by the broken line, so that the dehumidification tower 3 dehumidifies and the dehumidification tower 2 regenerates the desiccant in the same manner as above. This is then repeated alternately.

Arithmetic methods other than expressions may be used. In addition, switching the dehumidification tower,
As mentioned above, at time t. At this point t
It may be carried out a short time before the set dew point P.
Instead of using the specified dew point value of the dehumidifier as described above, you may use a dew point value that is slightly lower than this specified dew point value, and in both of these cases, the maximum actual gas dew point value is This is more preferable since the dew point is maintained lower than the specified dew point.
