Abstract

The invention discloses an energy-saving compressed air drying method and an energy-saving compressed air drying device special for compression heat regenerative pipelines. The method comprises the following two stages: a drying-heating regeneration stage, wherein high temperature gas is delivered to a regenerator, enters an air cooler for temperature reduction, flows into a gas-water separator and then enters a drying tower; and a drying-cold blowing regeneration stage, wherein the high temperature gas is controlled by a valve to change the direction, flows into the air cooler and the gas-water separator and then directly enters the drying tower for drying, wherein partial dried air taken from an outlet of the drying tower enters the regenerator for cold blowing regeneration. The device comprises a pair of adsorption towers which are formed by connecting a plurality of control valves and pipelines and is a drying tower and a regenerator mutually; the control valves are connected with a PLC program controller; a pipeline for delivering high temperature air is connected in parallel with a dry air supply pipeline formed by connecting the air cooler and the gas-water separator in series; and the front end of the dry air supply pipeline is connected with an outlet of a regenerative gas pipeline of the regenerator through a control valve. The energy-saving compressed air drying method and the energy-saving compressed air drying device avoid the defects of short switching time, high frequency and high gas consumption for generation of a heatless regenerative adsorption type drier, also overcome the defect that a heat regenerative adsorption type drier needs a heater to consume much electric energy, and ensure continuous production of high-quality gas and energy conservation.
