Detailed explanation of common compressed air purification equipment

Commonly used compressed air purification equipment includes gas storage tanks, dryers (refrigerated and filters), and filters.

　　一: Gas tank

The function of the air storage tank: store compressed air; buffer pressure, because the pressure of the compressed air discharged by the air compressor has certain fluctuations, after the air storage tank is installed, the compressed air at the air end can be used more stably; the water is pre-eliminated in the air Part of the water vapor has been compressed by an air compressor to form liquid water droplets. Most of these water droplets will be deposited on the bottom of the gas storage tank when they pass through the gas storage tank. There is a drain valve at the bottom of the gas storage tank, which is manually or automatically discharged.

　　 Gas tank options

When selecting the gas storage tank, the pressure should be consistent with the working pressure of the air compressor, and the volume is about 1/5-1/10 of the volume flow of the air compressor; if the environmental conditions permit, a large-volume gas storage tank can be selected to help For storing more compressed air and better pre-dewatering.

　　 Two: Dryer

Dryers are divided into two types: refrigerated and adsorption (module and core). Adsorption dryers are divided into non-heating and micro-heating types according to the heating type; adsorption dryers are commonly used, which are currently the most advanced on the market. The adsorption dryer is the latest core dryer developed by okmarts.com.

　　Because the compressed air contains 100% relative humidity moisture, as it cools in the pipeline, the moisture will precipitate, which will bring many disadvantages to the gas equipment. The adsorption dryer uses the adsorption characteristics of the adsorbent to dry and adsorb the moisture in the compressed air, which is discharged by the automatic drain valve and muffler, and the pressure dew point can generally reach -20°C to -70°C.

　　Adsorption dryer specifications

　　 1. The processing flow rate of the dryer is close to the volume flow rate of the air compressor

　　2. The working pressure of the dryer is equivalent to the outlet pressure of the air compressor

　　3, the outlet temperature of the air compressor

　　三: Filter

　　 In addition to water, compressed air contains oil, dust and various odor components. The equipment that physically filters and removes these compressed air pollutants is called a filter.

　　 filter option

The optional filter must be increased step by step in the order of the filtering accuracy level. You cannot skip the previous filter level and directly select the subsequent filter level, for example: install P-level filter (pre-filter), U-level filter (coarse Filter), H-grade filter (pre-filter), F-grade filter (post-precision filter); the filter flow can be selected and matched with the air compressor volume flow.
