Description

one

The invention relates to control systems for rotary air dryers and can be used for drying air.

The purpose of the invention is to stabilize the air humidity at the outlet of the air purifier.

FIG. 1 illustrates a control system for a rotary dryer; FIG. 2 is a section A-A in FIG. one,

The system consists of a rotor 1 with a layer of sorbent, claws 2, sensor 3 relative humidity of dry air, fan 4 of drainage and fan 5 of regeneration, motor 6 rotating rotor, heater 7 of regenerative air, moving pair of partitions 8 in covers 2, fixed pair of partitions 9, rigidly connected with KpbmiKatvffi 2, a turning motor 10, a stem P, with which a mobile pair of partitions 8 are rigidly connected.

The system works as follows.

The air is taken in by the drying fan 4, the drying tower B is supplied to the compressor, passes through the sorbent, is dried and, by means of flow, the relative humidity sensor 3 of the dried air re-enters the room to be dried. At the same time, the regeneration fan 5 flows atmospheric air into the heater 7, heats it up to the regeneration temperature and enters the regeneration sector B, dries it and is released into the atmosphere.

Since the rotor 1 is constantly rotated by the motor 6, both processes occurred

d t continuously. When dehumidified air enters the drying sector B, the process becomes ineffective. Sorbent earlier in time

is saturated with moisture, leakage of humid air occurs, and the relative humidity of the dried air increases, which is monitored by the relative humidity sensor 3. Signal of high humidity at the exit from

the dryer drives the motor 10 of rotation, turning the rod 11 and rigidly connected with it a movable pair of partitions 8 so that the sector

Drying B decreases slightly, and the regeneration sector C increases accordingly. In this case, the sorbent will be less in time in the dehumidification sector B and the humid air will be eliminated. Since the absorption of the sorbent will still be more complete, its regeneration will require a lot of time, which will be achieved by a corresponding increase in the regeneration sector B, When the less humid air enters the drying sector B, the sorbent does not manage to collect the calculated amount of moisture therefore, the relative humidity of the dried air is reduced. A relative humidity sensor 3 feeds a rotation motor 10, which increases the drainage sector.

B and reduces the regeneration sector B, since in this case the less saturated water sorbent enters the regeneration sector C, it is completely regenerated.
