Description
Technical Field
The invention relates to the technical field of adsorption dryers, in particular to a vacuum regeneration adsorption dryer.
Background
With the continuous improvement of the industrial technology level, compressed air becomes an important power source and is widely applied to multiple industrial fields such as petrifaction, metallurgy, national defense and the like. The water content of the compressed air is a key index for measuring the quality of the compressed air, and when the water content is too high, serious adverse effects are often caused to production equipment and product quality, so that the compressed air needs to be dried.
The adsorption dryer is a drying device commonly used for compressed air, and the purpose of repeated use is achieved by adsorbing water vapor in the compressed air by using an adsorbent filled in the device and then activating the adsorbent through regeneration. The adsorption type dryers may be classified into heatless regeneration adsorption dryers, micro-heating regeneration adsorption dryers and blast heat regeneration adsorption dryers according to the adsorbent regeneration method. The heatless regeneration adsorption dryer and the micro-heating regeneration adsorption dryer need to perform desorption regeneration on the adsorbent by drying finished air, and although the energy consumption is low, a large amount of finished air needs to be consumed; the air-blowing heat regeneration adsorption dryer can realize zero loss of finished gas, but high-temperature heat energy for adsorbent regeneration is usually only used for one time, so that the energy consumption is high, and the requirements of energy conservation and environmental protection are difficult to meet.
