Description
Technical Field
The application relates to the technical field of micro-thermal regeneration dryers, in particular to a micro-thermal regeneration dryer control and fault display system.
Background
The micro-thermal dryer is a device for drying compressed air by a micro-heating regeneration method. Under a certain pressure, the compressed air flows through the adsorbent bed layer from bottom to top, and under low temperature and high pressure, the water vapor in the compressed air is transferred to the surface of the adsorbent, i.e. the adsorbent absorbs the water in the air to reach a state of equilibrium, so that the compressed air is dried. The defects that a non-thermal dryer is short in switching time and large in regenerated air consumption are overcome by the micro-thermal dryer, and the defect that a thermal dryer consumes large electric energy is overcome. In addition, when the micro-heating part fails, the micro-heating drier can be automatically switched to a non-heating operation mode. The micro-heating dryer has the advantages of simple and elegant structure, stable pressure dew point, low energy consumption, convenience in operation and maintenance and the like. And an RS485/RS232 joint transport interface is arranged, so that remote communication, centralized monitoring and air compressor joint control can be performed.
