Description

Technical Field

[0001] The utility model relates to the field of dryers, in particular to an energy-saving zero-gas-consumption blast regeneration dryer. Background Art

[0002] Most existing dryers are designed with twin-tower drying drums, which consume a portion of the dried compressed air, then heat and cool the original desiccant for recirculation. This type of dryer is inefficient, and the regenerated air is directly vented, wasting precious resources and reducing production efficiency.

[0003] To address the above-mentioned issues, a Chinese patent application with the authorization publication number CN219580207U was found to disclose a high-efficiency, energy-saving, zero-gas-consumption blast heat adsorption dryer. The invention relates to a process in which air flows in from the second air inlet 510, passes through the blower 520, the heater 530, the fourth air inlet valve 450, the second adsorption cylinder 320, and the fourth air outlet valve 250, and finally flows out from the second air outlet 540.

[0004] Although the above-mentioned dryer can heat the gas through the heater 530 when in use, when the gas is heated by the resistance wire inside the heater 530, some gas is overheated and some gas is underheated, resulting in uneven drying of the gas. For example, in a compressed air system, insufficiently dried gas may cause rust and corrosion of equipment, affecting the normal operation of pneumatic tools and equipment. Utility Model Content

[0007] Preferably, the drying heating cylinder is connected to the outlet pipe of the zero-gas consumption dryer through the outlet connecting flange at the top, and the drying heating cylinder is connected to the inlet pipe of the zero-gas consumption dryer through the inlet connecting flange at the bottom. At the same time, the diameters of the outlet connecting flange and the inlet connecting flange are consistent, and five groups of mounting holes are evenly arranged on the outlet connecting flange and the inlet connecting flange.
