Some knowledge points about adsorption dryers, told by the accessories manufacturer of adsorption dryers
Adsorption dryer accessories The manufacturer believes that the oil content of the inlet air of the adsorption dryer should be controlled below 0.01mg/m3; considering that oil-free air compressors cannot currently achieve oil-free operation, in order to prevent the accumulation of trace amounts of oil in the adsorption bed (this accumulation is very fast), an oil remover needs to be installed at the inlet of the dryer. The adsorption dryer should be used at the rated temperature and pressure. When the inlet temperature is higher than or the inlet pressure is lower than the rated value, the capacity should be corrected.
Adsorption dryer accessories The manufacturer believes that when the adsorption dryer is used with a piston air compressor, a pressure stabilizing storage tank should be installed in front to prevent the high-speed impact of pulsating airflow on the adsorbent. Avoid deliberately "saving energy" to reduce regeneration gas consumption (including regeneration gas volume and heating power); when there is "air dryer pre-installation," as long as the site permits, the adsorption dryer and the air dryer should be installed separately as much as possible to reduce air pressure drop, improve the ventilation conditions of the air dryer, and facilitate daily maintenance.
The manufacturer of adsorption dryer accessories believes that traditionally, adsorbent, controller, valves, and silencers are collectively referred to as the four easily damaged parts of the dryer.
1. The manufacturer of adsorption dryer accessories believes that the adsorbent, as the industrial main body of the dryer, is subjected to frequent impacts of pressure, water vapor, and heat for most of the time, and is easily mechanically broken and contaminated by the medium, causing the performance of the adsorbent to deteriorate. Since activated alumina replaced silica gel as the main adsorbent, various performances have been greatly improved, especially the compressive strength and resistance to liquid water immersion have reached a high level. As long as there are no operational factors such as "insufficient regeneration energy consumption," the dew point of the compressed air treated with activated alumina can stably reach -40, and the service life can reach more than 2-3 years.
2. The controller is the command center of the adsorption dryer. With the development of auxiliary electronic technology and the widespread application of PLC technology, the control accuracy and reliability are superior to those of early electromechanical control. In addition to the further improvement of the anti-interference and overload capacity of the heating regeneration components, other control components are no longer easily damaged parts.
3. The manufacturer of adsorption dryer accessories believes that the control valve is a very easily damaged part in the adsorption dryer. Frequent switching and long-term mixed intrusion of water and adsorbent debris are important reasons for valve leakage.
4. Adsorption dryer accessories The manufacturer believes that the silencer is a part that is prone to failure, mainly manifested as blockage of the silencer exhaust channel. Once the silencer fails (blockage), the damage to the entire machine is fatal, leading to a decrease in the regeneration performance of the adsorbent and premature aging. Therefore, the silencer is the daily maintenance of the adsorption dryer.
