The working principle of

JXG series zero air consumption blast regeneration adsorption dryer produced by our company is a kind of energy-saving compressed air drying device. It adopts the process of environmental air blast regeneration, so it can save a lot of product gas required by traditional process regeneration.The adsorption principle of zero air consumption blast regenerative adsorption dryer is similar to that of traditional micro-thermal/non-thermal adsorption dryer.But its regeneration method is the blast regeneration process, process steps include heating, blowing cold.During heating, the regenerative air source comes from the ambient air after the blower pressure boost, and is heated to the regenerative temperature by the heater as the recycled gas resolved by the adsorbent.In the regeneration operation, the regeneration heating gas is used to heat the adsorption bed, and the water vapor precipitated by the regeneration gas is carried out and carried out of the adsorber.Regenerative air conditioning also uses ambient air for air circulation cooling separation as regenerative air cooling gas to blow cold the bed, in order to meet the needs of the next stage of adsorption work, to avoid the air outlet dew point due to the existence of bed temperature and instability.

The working process

The adsorption

The compressed air containing a large amount of water vapor enters the adsorption tower through the air inlet, passes through the efficient diffusion device, and then diffuses through the adsorption tower.The water vapor is absorbed by the adsorbent as it passes through the adsorption column.The dried compressed air is fed into the air pipe network through the outlet.

Heating regeneration stage

In one tower adsorption at the same time the other tower regeneration process.Before that, the pressure in the tower will be lowered to atmospheric pressure by the pressure relief system.

Use ambient air for regeneration

First, a blower draws in ambient air and pressurizes it to the regeneration pressure, then a heater heats the air further to the regeneration temperature (~ 130 ° C).Under the continuous action of the blower, the hot air flows into the adsorption bed, and the desaturation and evaporation of the hot air are used to regenerate and dry the adsorbent.

Purge the stage

At the end of the heating process, the cold blowing stage is also carried out with ambient air.A unique way of cold blowing the closed water cooling system, through the combination of the valve action to form a closed loop system, fan as a driving force power cycle, make the hot air inside the adsorption tower continuous heat exchange with water cooler, cold air cooled again into the absorption tower, take away the quantity of heat of adsorbent, the temperature of the lower the temperature of the best adsorbent.
