Problems solved by technology

If the phenomenon of "incomplete regeneration" occurs in the regeneration stage, the surface activity of the desiccant will not recover to the original level, which will affect the outlet dew point of the treated compressed air, and the accumulation of residual moisture in the desiccant will affect its service life
Therefore, in order to avoid "incomplete regeneration", the existi

Abstract

The invention discloses a heatless regenerative adsorption dryer. Based on the prior art, a first drying tank and a second drying tank are increased in the dryer, wherein the first drying tank is arranged at any position between a first drying tower and a regenerative gas passage, the second drying tank is arranged at any position between a second drying tower and the regenerative gas passage, and an adsorbent is filled in the first drying tank and the second drying tank; and porous plates arranged on two sides of the adsorbent and a waveform spring for fully compacting the adsorbent between the porous plates are arranged in the first drying tank and the second drying tank respectively. The heatless regenerative adsorption dryer provided by the invention reduces regenerative gas consumption at the same time of improving the dryness of the regenerative gas through the first drying tank and the second drying tank, reduces the waste of energy and the emission of waste gas, and improves the drying efficiency.

Description

A heatless regenerative adsorption dryer technical field The invention relates to a gas drying device, in particular to a heatless regenerative adsorption dryer. Background technique The heatless regenerative adsorption dryer utilizes the principle of pressure swing adsorption to remove moisture from compressed gas. The current structure of the dryer is a double-tower type, and the drying tower and the regeneration tower work alternately and reciprocally to achieve the purpose of drying. Its working cycle is divided into two stages of adsorption and regeneration: in the drying stage, the pressure of the drying tower increases, and the partial pressure of water vapor in the air also increases accordingly. When passing through the desiccant bed, the water vapor is absorbed by the desiccant, making the desiccant The partial pressure of water vapor on the surface gradually increases and reaches equilibrium, so that the compressed air is dried; during the regeneration stage, t...
