Air dryer, find out

The air dryer is basically an original part of the air brake truck. Its function is to remove the moisture from the compressed air and turn it into dry air to ensure the dryness of the brake air for the truck. The moisture in the air will condense in the pump valve, causing brake failure and brake drag failure.

But the air dryer is like a sponge, it will lose its function after it is full of water. So is there any way to remove the moisture from the dry particles like wringing out a sponge, so as to extend the life of the dryer?

The main ingredient in the drying tank is a lot of water-absorbing particles, these particles can be understood as common sponges in life. You can imagine that after the sponge is full of water, you have to wring it out before it can absorb water again. The same is true for the particles in the drying tank. If the absorbed water is not removed in time, it will quickly absorb the water and lose its effect. How to achieve the purpose of removing water? After the compressed air reaches the specified air pressure and the unloading valve is unloaded, the dried air is used to blow the drying tank in turn to achieve the purpose of removing moisture. This is the back-blowing regeneration device on the drying tank.
