Abstract

The invention provides a proton accelerator cooling water temperature control system and method. A secondary cooling water circulation system ensures that the temperature of output secondary cooling water meets the technological requirement through the PID control of cooling tower fans and the control of a second electromagnetic three-way valve of frozen water, and primary circulating water cooledby a load and secondary cooling water exchange heat through a primary plate exchanger to reduce the temperature. In addition, a primary cooling water control system makes the cooling water meet the cooling requirement of proton acceleration equipment through common adjustment of the serial PID control of a first electromagnetic three-way valve of secondary cooling water and the PID control of electric heaters.

Description

technical field [0001] The invention relates to a proton accelerator cooling water temperature control system and method Background technique [0002] The proton knife is currently the mainstream radiotherapy method for cancer tumors. The main equipment of the proton accelerator is composed of a huge number of magnets, which will generate huge heat energy during operation, and due to its radiation protection requirements, the equipment is installed in a closed area. The operating temperature of the accelerator will directly affect the working status of related medical equipment. What's more, if the temperature of the proton accelerator exceeds the critical value, there will be huge unpredictable radiation hazards. How to ensure the normal operation of the proton accelerator at the required temperature is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to provide a proton accelerator cooling water temper...
