Embodiment

[0055] Please refer to the attached Figure 1-3 As shown, the embodiment of the present invention discloses a fresh air dehumidification and drying system for a gallery of a hydropower station. The gallery of the hydropower station includes a main gallery and a number of sub-galleries, and the sub-galleries and the main gallery are arranged vertically and horizontally. The system includes a fresh air pretreatment unit 100 and a jet dehumidification unit 200. The fresh air pretreatment unit 100 is arranged at the air intake of the main gallery, and the jet dehumidification unit 200 is arranged in each sub gallery. The pretreatment unit 100 includes a first filter 11, a surface cooler 12, a first refrigeration system 13, a regenerator 14 and a first blower 15. The fresh air pretreatment unit 100 inhales fresh air from the air intake and passes through the first After the filter 11, the surface cooler 12, the first refrigeration system 13 and the regenerator 14, they are sent int...

Abstract

The invention discloses a fresh air dehumidification drying system for a hydropower station gallery and a control method of the fresh air dehumidification drying system. The hydropower station gallerycomprises a main gallery body and a plurality of branch gallery bodies, wherein the branch gallery bodies and the main gallery body are arranged in a crisscross manner; the system comprises a fresh air pretreatment unit and jet flow dehumidification units; the fresh air pretreatment unit is arranged at an air taking opening of the main gallery body; and the jet flow dehumidification units are arranged in the branch gallery bodies. The fresh air dehumidification drying system solves the problems that fresh air in the hydropower station gallery brings in the wet load, and distribution is not uniform. According to the system, the fresh air pretreatment unit and the jet flow dehumidification units are utilized in a combined manner, the fresh air and the gallery wet load are independently treated, the wall-attached jet flow distance of jet flow air openings of the jet flow dehumidification units is utilized, the fresh air is evenly distributed in the whole gallery space, and the problem ofa dilution blind area is solved.

Description

technical field [0001] The invention discloses a fresh air dehumidification and drying system for corridors of hydropower stations and a control method thereof, belonging to the field of dehumidification and drying of corridors of hydropower stations. Background technique [0002] In order to alleviate the energy crisis, countries around the world vigorously advocate and actively develop and utilize water resources. Hydropower stations are the concentrated expression of the utilization of water energy resources and have broad prospects for development. In addition to high humidity, the environment in the hydropower station corridor also contains a small amount of flammable and explosive gases. Therefore, in order to ensure the normal and stable operation and service life of the process equipment, the humidity control in the hydropower station corridor and the treatment of air pollution sources have become urgent solutions. question. [0003] At present, the hydropower stati...
