Air drying equipment and equipment operating procedures

Abstract

The invention relates to an air drying device comprising a first adsorption column (1), a second adsorption column (2) packed with activated aluminum adsorbent material, a buffer tank (4) containing the product of the air, connected by lines with air supply valves (11) and (12), discharge valves (13) and (14), check valves (19) and (20), pressure regulating valve (17), product collection check valves (15) and (16), flow control valve (21), PLC controller (18) and noise suppressor (3). In which, by using a system with a pressure regulating valve (17) at the outlet between the two adsorption columns, it is possible to quickly balance the pressure and utilize the semi-finished gas in the adsorption column, allowing the device to operate continuously. By arranging a buffer tank (4) with a flow control valve (21) and one-way valves to return dry air to the outlet of the adsorption columns, it is possible to control the amount of dry air used to load the active material group. At the same time, the arrangement of noise reduction (3) helps the amount of exhaust gas to be completely and quickly released, improving the process of regenerating activated aluminum material while effectively reducing noise and extending the lifespan. The invention mentions the equipment operation process to facilitate automation, allowing for smooth operation with high efficiency and energy saving.
