The catalytic hydrogenation deoxygenation apparatus is integrated on a pedestal, is debugged and then is integrally conveyed to a site, so the apparatus is safe and convenient to install, debug, use and repair.

Description

technical field [0001] The invention relates to a catalytic hydrogenation and oxygen removal device, in particular to a modular catalytic hydrogenation and oxygen removal device for nuclear power plants. Background technique [0002] The existence of dissolved oxygen in water is an important cause of corrosion of power plant system equipment and pipelines, so nuclear power plants have particularly strict requirements on the oxygen content of operating water. Catalytic hydrogenation technology is usually used to remove oxygen. This technology has wide application range, high oxygen removal efficiency, large processing capacity, no pollution and side effects. However, in order to make the dissolved oxygen in the treated water supply as low as possible, excessive hydrogenation is often used The operation mode of the system brings about the increase of operating cost and the safety issue of hydrogen emission. At the same time, the implementation of this technology requires mult...

Problems solved by technology

Catalytic hydrogenation technology is usually used to remove oxygen. This technology has wide application range, high oxygen removal efficiency, large processing capacity, no pollution and side effects. However, in order to make the dissolved oxygen in the treated water supply as low as possible, excessive hydrogenation is often used operating mode, which brings about the increase of operating cost and the safety issue of hydrogen emission

At the same time, the implementation of this technology requires multiple pieces of equipment, valves, pipelines, and instruments. Among them, the main equipment is shipped to the site after processing in the factory, and the connecting pipelines, valves, and instruments are installed on the construction site. Due to the large number of related interfaces And on-site production conditions are limited, especially the working environment has the risk of radioactive pollution, and its quality and project progress are often difficult to guarantee
