Problems solved by technology
[0003] However, in the actual production process, due to the obvious thermal expansion and contraction effect after the system feed liquid enters the degasser, the existing system cannot effectively respond to the parameter changes caused by the thermal expansion and contraction effect, resulting in the degasser Unable to start normally or stop degassing due to failure after starting, requiring a lot of manpower and material resources for on-site manual debugging

The invention relates to the technical field of nuclear power plant three-waste treatment systems, and relates to a degasser starting control method and device, equipment and a degassing system for anuclear power plant. Historical data, within a preset time period before the current time, of the degassing system are acquired, and the target working parameters, related to the degasser state parameters, of each regulating valve are acquired according to the historical data; a mapping relationship between the target working parameters and the corresponding state parameters is acquired accordingto the corresponding data of the target working parameters and the state parameter data in the historical data; a numerical range of the corresponding target working parameters is acquired according to the numerical setting range and the mapping relationship of all the state parameters when the degasser is normally started; and therefore, each regulating valve is controlled to work within a corresponding numerical range, the degassing system can effectively respond to parameter changes caused by thermal expansion and cold contraction effects, and degassing production is normally started.
Description
technical field [0001] The present invention relates to the technical field of three waste treatment systems in nuclear power plants, in particular to a degasser start-up control method, device, equipment, and degasser start-up control method, device, equipment, and degasser system for nuclear power plants . Background technique [0002] The Boron Recovery System (TEP) is a system that collects hydrogen-containing reactor coolant and processes it through a purification section and a water / boric acid separation section to obtain reactor-grade make-up water and boric acid concentrate for reuse in the reactor coolant system. Among them, the purification section mainly uses the degasser to remove the hydrogen and radioactive gases collected by the TEP system. [0003] However, in the actual production process, due to the obvious thermal expansion and contraction effect after the system feed liquid enters the degasser, the existing system cannot effectively respond to the parame...
