Description

Technical Field

[0001] This utility model relates to the field of thermal regeneration drying tower technology, specifically a steam heat recovery type compression thermal regeneration drying tower. Background Technology

[0002] The steam heat recovery type compression heat regeneration drying tower is a highly efficient and energy-saving compressed air drying equipment. It combines compression heat regeneration and steam heat recovery technologies, significantly reducing energy consumption and improving drying efficiency. The drying tower works by using high-temperature compressed air (typically 80–100°C) discharged from the air compressor as the regeneration gas to directly heat the desiccant. When the compression heat is insufficient (e.g., under low load conditions), steam is introduced as an auxiliary heat source to ensure a stable regeneration temperature (typically 160–200°C), preventing desiccant performance degradation. Waste heat from the discharged regeneration exhaust gas is recovered through a heat exchanger and used to preheat the humid air entering the drying tower, reducing the system's total energy consumption. In existing drying towers, the intermittent operation of the compressor causes fluctuations in the supply of hot air, while the steam supply is difficult to adjust, leading to excessive steam waste during high-power compressor operation. Therefore, improvements to the existing technology are necessary. Utility Model Content

The first bevel gear 10 meshes with the second bevel gear 11 and can drive the internal threaded pipe 9 to rotate. The outer side of the air intake hood 3 is fixedly connected to a bent pipe 14, which is fixedly connected to the input pipe of the drying tower 13. The bent pipe 14 can transmit steam.
