The design of the internal structure of the adsorber: the design of the internal structure of the adsorber includes the determination of the bed layer and various auxiliary structures, such as the design of the upper and lower filter, the guide valve, the pressing mechanism, the gas distribution device and so on. The adsorber can usually be divided into single bed and double bed, and the structure is shown in figure 3. Both the upper and lower vent of the two structures are equipped with filter and gas distributor. The single-layer bed structure is equipped with a screen hole plate and a cylinder compressing device on the molecular sieve adsorber. When the adsorber is working, the cylinder piston generates a lower thrust by differential pressure and compresses the molecular sieve through the screen hole plate, it avoids the phenomena that the molecular sieve is boiling and flowing and the filter screen is damaged due to the excessive airflow, thus prolonging the life of the molecula...

In the temperature of the forward air into the cooler (hot end temperature, related to the cooling effect of the last cooler of the air compressor or nitrogen water precooler) and the temperature of the return air into the cooler (cold end temperature, under the condition that the temperature of the heat exchanger such as the outlet supercooler and the liquid purifier is not changed, the temperature difference between the thermal end and the temperature difference between the cold end of the refrigerator (both refers to the difference between the temperature of the forward air and the reflow gas participating in the switching) is interdependent. If the hot end temperature difference, cold end temperature difference will is too small; the hot end temperature difference is too small, cold end temperature difference will is too large. This is decided by the cooling balance of the positive and return gas of the cooler. When the ratio of return flow to positive flow volume is larger than...
