Abstract

The utility model discloses an energy-saving and environment-friendly compressed gas drying system, which is applied to the field of gas drying equipment and comprises a first gas inlet pipe communicated with a second gas inlet pipe. According to the utility model, the adsorption tower, the cooler, the separator, the heater, the filter and the program control valve are connected into a net by utilizing each pipeline, so that adsorption, regeneration and pressure equalization are realized, the water content of gas entering the system is reduced, the quality of product gas is improved, and the energy consumption and the production cost can be reduced at the same time; according to the utility model, low-dew-point dry gas is prepared, and regenerated gas during cold blowing is recovered by utilizing the process of the device, so that the regenerated gas flows back in the system for recycling, the finished product gas is completely not consumed, and the cost is reduced; the whole process is free of emptying, noise and pollution caused by sudden discharge of compressed gas are eliminated, switching is stable, the service life of an adsorbent is prolonged, zero discharge is completely achieved in the process, and energy is saved.
