Embodiment 1
[0035] see Figure 1 to Figure 5 , a nuclear power plant filter steel structure module, including a filter, the filter includes a filter housing 9-1; a filter element 9-2 embedded in the filter housing 9-1; located in the filter housing 9- 1 on the exhaust port, the filter upper inlet, and the filter lower outlet; the flange structure 9-6 located at the top of the filter housing 9-1, the center of circle of the exhaust port, the center of circle of the filter upper inlet, The circle center of the lower outlet of the filter is located on the same vertical line, and it is characterized in that it also includes a steel structure for accommodating the filter;
[0036] ——The steel structure includes:
[0037] A steel casing 1 with an opening at the top is used to accommodate the filter; it has a certain thickness, which can realize the shielding of the radiation dose increase caused by the accumulation of radioactive substances during the operation of the power plant;

The invention relates to the technical field of nuclear power plant filters, and in particular, relates to a nuclear power plant filter steel structure module which comprises a filter, a filter element, an exhaust port, a filter upper inlet, a filter lower outlet and a flange structure; the filter comprises a filter shell; the filter element is embedded in the filter shell; the exhaust port, the filter upper inlet and the filter lower outlet are formed in the filter shell; and the flange structure is arranged at the top of the filter shell. The nuclear power plant filter steel structure module is characterized by further comprising a steel structure used for accommodating the filter; and a mounting skirt at the top of the steel structure is used for being clamped and embedded in an opening of a floor or a steel platform. Compared with the prior art, the nuclear power plant filter steel structure module has the advantages that the modular design is adopted; the installation is simple; the steel structure module is prefabricated in a factory in advance and can be carried out in parallel with item construction in a factory site, and the construction period is short; retirement is convenient; the steel shell has shielding and supporting functions; and the containing cavity of the shell can be matched with installation of filters of the same type.
Description
technical field [0001] The invention relates to the technical field of nuclear power plant filters, in particular to a nuclear power plant filter steel structure module. Background technique [0002] Nuclear power plant filters are generally installed upstream or downstream of the resin bed to trap activated carbon in the resin bed or impurities in the filter medium. Through its filtering function, it can guarantee the normal function of the resin bed and ensure the normal operation of the system. . Because it is mainly used in nuclear power plant chemical and volume control, spent fuel pool cooling, radioactive waste liquid treatment and other systems, it will face the problem of regular replacement and decommissioning under high radioactive conditions. [0003] The traditional installation method is generally fixed by equipment support, or connected with the filter through the embedded structure in the floor to complete the equipment installation. These installation meth...
