How to Replace the Adsorbent in a Regenerative Desiccant Dryer
The adsorption dryer uses chemical technology. Its principle is to use the difference in the volume of moisture and air molecules in the saturated compressed air. It uses a special activated alumina ball desiccant for gas purification and molecular sieves to filter out the saturated water vapor in the compressed air. Easily absorb water molecules in the activated alumina ball desiccant and molecular sieve particles, and then use the regeneration method to restore the air compressor desiccant molecular sieve, and the compressed air dew point can easily reach -40°C or below.
According to the air compressor activated alumina desiccant regeneration method, it can be mainly divided into two types: non-heat regeneration micro-heat regeneration desiccator and heat regeneration micro-heat regeneration desiccant machine. Since the heatless and micro-heat regenerative desiccant works according to isothermal adsorption, it is also called "pressure swing adsorption".
Let me introduce in detail how the adsorption dryer replaces the desiccant of the air compressor.
1. The coarse filter screen installed on the inlet and exhaust pipe joints of the tower is detachable on all models. It is recommended to remove and clean these filters when changing the desiccant. The strainer is accessible after the upper/lower manifold is removed from the drying tower.
2. After the coarse filter is cleaned, install it again, and then plug the outlet plug.
3. After removing all filler plugs, inject desiccant of appropriate grade and specification. The height level of the desiccant of the air compressor should meet the requirements of the desiccant filling table.
4. Once the two towers are filled, re-plug the filling port of each tower.
In addition, when replacing the desiccant of the air compressor of the adsorption dryer, attention should be paid that it must be dense and there are no gaps, which will easily cause the adsorbent in the adsorption tower to pulverize and cause huge economic losses.
