* The compressed air produced by the compressor contains a significant amount of water, oil and other impurities. Especially the water vapor that may condense inside the compressed air and then enter the air distribution line and cause oxidation, corrosion and serious damage to the production line equipment.
* The maximum condensation point of water vapor in any gas depends on its temperature and pressure. When the condensation of water reaches a certain temperature and working pressure, that temperature indicates the dew point, that is, if the air cools below the dew point, the water vapor in the air it appears as water droplets, which causes problems in the production line.
* The dew point of refrigeration compressors is very limited and the minimum pressure related to its dew point is about +2°C, so when we need better quality dry air at a certain ambient temperature, only absorption dryers (YSD) are the answer.
* Cases of use of discount dryer (absorption) series (YSD)
When a certain dew point is considered (especially below zero temperature)
The process of controlling equipment and production line, photography, pharmaceutical and food industries, fireproof areas, flat places where the ambient temperature reaches below zero degrees Celsius.
Control system
The recovery stage and the appropriate cycle do not always work in the same way and at the same time, but it depends on its working conditions. Especially the compressed air inlet temperature, operating pressure and air flow that should be controlled in the dryer. For this reason, all units in this type of dryer are connected with a microprocessor control system that shows the following functions:
* Half-cycle time adjustment
* Set recovery time
* Drying stage
* Recovery stage
electricity consumption
The electricity consumption in the YSD series dryer is very low and does not exceed the few watts needed to operate the controllers and two electric valves.
Dryer constituent unit
YSD series dryer is absorption type, 2 carbon steel towers, along with absorption materials inside, four electric valves made of brass and moving parts made of stainless steel, two one-way valves, one bypass pipe, microprocessor system and screen which facilitates the transfer of the dryer.
Control unit
The control unit is installed in a place that is easily accessible. This type of dryer is equipped with a silencer to reduce noise pollution.
Device pressure
The working pressure of this type of dryer is different, so that the working pressure of some models is up to 26 bar, and for bigger models, this amount changes by 10 bar.
How the device works:
Dryer (YSD) through four electric valves whose task is to balance the air flow between the two towers. It dries the air.
(A
1- First, the compressed air enters one of the two towers from the bottom of the tower.
2- For a certain period of time, water vapor is transferred to absorbent materials, and at the same time, 15% of the dried air passes through the by-pass pipe.
3- The transfer and removal of moisture from absorbent materials that have been absorbed in the previous cycle. The duration of this stage, which is known as the regeneration stage, is shorter than the air drying stage, because it gives the regenerated tower the opportunity to work again. earned himself
(B
With the arrival of compressed air, a new cycle begins (1)
At the same time, the other tower is being restored (2).
Absorbent material
The absorption material inside the towers is active alumina (AL203) and its dew point reaches -40°C. These materials absorb the steam in the compressed air and then enter the air flow for regeneration.
