Description

Technical Field

[0001] The utility model relates to the technical field of energy saving of desulfurization oxidation fans, in particular to an air cooling system for a desulfurization oxidation system. Background Technique

[0002] Under the current technical conditions, in the limestone-gypsum wet flue gas desulfurization system, traditional Roots fans have problems such as low efficiency, high energy consumption, large noise and vibration, and high temperature. The equipment failure rate is relatively high, and the overhaul and maintenance workload is large, which has become the main limiting factor for the continuous and stable operation of the wet desulfurization system. Therefore, upgrading the original Roots fan to a magnetic levitation fan can effectively improve the energy-saving performance and energy efficiency level of the desulfurization oxidation fan, thereby further reducing the power consumption of the desulfurization oxidation fan, reducing the power consumption of the desulfurization process, reducing the equipment operation noise, avoiding environmental pollution caused by oil leakage problems at the site, and reducing the investment in lubricating oil replacement and maintenance costs.

[0003] However, the current desulfurization oxidation system is equipped with an air cooling system, and additional cooling water is still required for cooling, which leads to a large energy consumption during the desulfurization operation. Therefore, an air cooling system for a desulfurization oxidation system is needed to solve the above problems. Content of the Utility Model
