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

Abstract

The present invention relates to the technical field of three waste treatment systems in nuclear power plants, and relates to a degasser start-up control method, device, equipment, and a degassing system for nuclear power plants. Obtain the target working parameters related to the state parameters of each control valve and the degasser from the historical data, and then obtain the mapping relationship between the target working parameters and the corresponding state parameters according to the corresponding data of the target working parameters and the state parameter data in the historical data; The value setting range and mapping relationship of each state parameter when the degasser starts normally obtains the value range of the corresponding target working parameter; thus, by controlling each regulating valve to work within the corresponding value range, the degassing system can effectively respond to thermal expansion Due to the parameter changes caused by the cold shrinkage effect, the degassing production is started normally.

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 startup control method, device, and equipment, and a degasser startup control method, device, and equipment for nuclear power plants and degassing systems 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 a degasser to remove the hydrogen and radioactive gases collected by the TEP system. [0003] However, in the actual operation and production process, due to the obvious thermal expansion and contraction effect after the system feed liquid enters the deaerator, the existing...
