The regeneration principle of adsorption dryers is similar. During use, the reasons for the decline and deterioration of gas source quality are roughly as follows.

　　Is the selection of the adsorption dryer reasonable?

　　Accurate selection of the adsorption dryer model is crucial. It is necessary to understand the user's market needs and then formulate corresponding plans to meet market demands. For example, if the user wants to obtain good gas source quality and low moisture content, understanding the incoming gas conditions is crucial. Based on the user's supplied incoming gas technical parameters (incoming gas working pressure, incoming gas total flow rate, incoming gas ambient temperature, etc.) and gas source processing needs, select suitable equipment. Below is a brief study on the direct impact of accurately selecting the dryer's incoming gas technical parameters.

　　The influence of the inlet temperature of the adsorption dryer. The gas to be processed by the dryer is usually saturated compressed gas, with a normal inlet temperature of 2-40°C. When the inlet temperature is too high, under the same flow rate and pressure, the absorbed water will increase significantly. The water-carrying capacity of saturated air is proportional to the temperature. For every 13°C increase in air temperature, the saturated water content in the air increases by about 1 times. That is, the inlet temperature has a significant impact on the equipment selection.

　　The adsorption material "aluminum oxide" has better low-temperature adsorption performance. If the exhaust temperature of the air compressor is too high in summer, the load of the post-treatment equipment will not only increase, but also the adsorption conditions will deteriorate. During regeneration, it is easy to cause incomplete regeneration of the dryer, resulting in large fluctuations. To ensure the regeneration effect, the regeneration gas volume and regeneration temperature will increase, thus greatly increasing the energy consumption of the equipment!

　　Therefore, the reasonable selection of adsorption dryers is very important!

　　Is the reasonable use condition of the adsorption dryer reasonable?

　　Even if the post-processing selection is reasonable, the dew point will still fluctuate. At this time, it is necessary to check whether the equipment is operating normally. The specific inspection methods are as follows.

　　Is the adsorption material of the adsorption dryer damaged? For example, if the air compressor leaks oil, and the corresponding filtration equipment cannot effectively filter out oil stains and other elements harmful to the adsorption material, it will lead to the formation of an oil film on the surface of the adsorption material, the so-called "oil poisoning", thus reducing or losing the adsorption capacity, which will seriously affect the dew point temperature.

　　Are the reasonable regeneration conditions of the adsorption dryer reasonably adjusted? Due to natural reasons, the load of the equipment will change greatly every year, so using a unified regeneration method will increase energy consumption, which is uneconomical and impractical! When the load is large in summer, it is very necessary to adjust the regeneration conditions in time.

　　Equipment parts malfunction. If the valve cannot operate effectively or leaks, it may cause the dew point to drop! When the equipment has an electrical fault, the machine cannot effectively switch tower operation, and valve operation or other related control electrical component failures will also cause the equipment to malfunction and lead to poor dew point.
