Refrigeration Air Dryer

The amount of water vapor in the compressed air is determined by the temperature of the compressed air: under the condition that the pressure of the compressed air is basically unchanged, reducing the temperature of the compressed air can reduce the content of water vapor in the compressed air, and the excess water vapor will condense into liquid. According to the corresponding relationship between the saturated steam pressure and temperature of water, the freezing dryer uses the refrigeration device to cool the compressed air to a certain dew point temperature, release the contained water, and discharge the water through the steam water separator and electric drainer, so as to dry the compressed air.

● Ensure the normal operation of the equipment at the ambient temperature of 50℃;

The cold dryer and the suction dryer can be connected in series to form a combined air dryer

Clean, low moisture content instrument or process compressed air is often required in chemical process. The refrigeration dryer is based on the principle of refrigeration dehumidification, while the heatless or slightly heated regenerative dryer is based on the principle of pressure swing adsorption to dry and dehumidify the compressed air. Generally, the pressure of compressed air is mostly 0.7-0.8Mpa, and the dew point of finished air under normal pressure can only reach about - 22 ℃ due to the restriction of refrigeration dehumidification principle.

The heatless and slightly heated regenerative adsorption dryer uses the unique micropores of the desiccant itself to adsorb water molecules in the air according to capillarity, and at the same time, remove the adsorbed water according to pressure relief desorption and adsorption waste heat heating. Generally, the dew point of dry gas under normal pressure reaches - 50 ℃. Operating pressure 0.7-0.8Mpa; Higher dew point of product gas can be achieved by mixing adsorbent and molecular sieve. The main problem of the micro heat regenerative adsorption dryer is the randomness of the heating temperature, because the micro heat regenerative adsorption dryer is similar to the heatless regenerative adsorption dryer, which uses its own low pressure dry air as regeneration gas. Therefore, in a large temperature range, even without heating the adsorbent, the active regeneration can be achieved according to the principle of "pressure swing adsorption".

The difference is that when the heating temperature is high, the desorption gas consumption is small. When the heating temperature is low, the desorption gas consumption is high. This randomness makes it difficult to unify the gas consumption index, so it is difficult to accurately grasp the regeneration degree of the adsorbent in specific operation. Under some false appearances, the regeneration gas consumption is too small, resulting in incomplete regeneration of the adsorbent. The best way to solve this problem is to formulate relevant national standards or industrial standards as soon as possible on the basis of theoretical research.

It is difficult to obtain dry air with dew point below - 50 ℃ by using refrigeration dryer or adsorption dryer alone, which must be used in series; Dew point of product gas can be reduced by increasing regeneration gas volume; Prolong the heating and regeneration time of the adsorbent, so that the adsorbent can be completely regenerated, and give full play to the regeneration effect, thus reducing the dew point of the product gas; In order to stably obtain dry air with dew point below - 50 ℃, the cold dryer and the micro heat regeneration dryer (or the heatless regeneration dryer) must be used in series.
