1. Heatless Regenerative Adsorbent Dryer Heatless regeneration desiccant dryer is using about 15% of the finished compressed air to purge and regenerate the saturated adsorbent; Advantages: simple construction, low acquisition cost and easy maintenance; Disadvantages are: consumes about 15% of high quality compressed air and is generally limited to applications below low flow rates due to high energy consumption. 2. Micro-thermal desiccant dryer Micro-thermal regenerative desiccant dryer requires the use of an electric heater, which heats about 8% of the finished gas through the heater and feeds it into the regeneration tower to warm up the adsorbent for regeneration, and then cold-blows the adsorbent to room temperature; The advantages are: longer working cycle compared to the heatless regeneration desiccant dryer, and stable dew point of the gas supply; The disadvantage is: energy consumption is still large, not only to consume 8% of compressed air, but also to consume a certain amount of electricity; 3. Zero gas consumption adsorption dryer Zero gas consumption adsorption dryer is an energy-saving compressed air drying device, which adopts the process of ambient air blast regeneration, so it can save a lot of product gas needed for regeneration of traditional process. The basic principle of adsorption in a zero air consumption blast thermal adsorption dryer is similar to the traditional adsorption process. However, the regeneration method is a blast regeneration process, and the process steps include heating and blowing cold. The source of regeneration gas during heating comes from the ambient air after the blower is pressurized and is heated by the heater to the regeneration temperature as the regeneration gas for the adsorber bed resolution. In the regeneration operation, the regeneration heating gas is heated to the adsorption bed resolution, and the water vapor precipitated by the regeneration gas is carried and brought out of the adsorber. Regeneration blowing cold or taken from its own dry air, after decompression as regeneration blowing cold gas, or air circulation cooling separation as regeneration blowing cold gas, the bed blowing cold to meet the next stage of adsorption work needs, to avoid the air outlet dew point due to the presence of bed temperature and instability. It is the most ideal energy-saving product for oil-injected screw air compressor at present. Advantages: more than 70% energy saving compared to heatless and micro-heat type desiccant dryers; Disadvantages: the system process is relatively complex, many pipelines and valves, high performance requirements of each component, relatively high
