Circulating water system of cyclotron and water saving method of circulating water system

Abstract

The invention relates to system design technology of the cyclotron, particularly to a circulating water system of a cyclotron and a water saving method of the circulating water system. A first water circulating and a secondary water circulating of the circulating water system are all in enclosed structures, and water evaporation and loss in water circulation channels is avoided. Optimization is performed on the system process including water supply and water quality improvement, and concentrated water is fully recycled (about 7tons / per day); about 1.5 tons of water is consumed in a backwashing of a pre-treatment system, a backwashing period is changed in a scientific and reasonable manner, with the conventional powered timing replaced by work timing, and unnecessary backwashing is greatly reduced. By the water saving method, 8tons water is saved per day, at the premise of high-quality quality of the circulating water, waste water drainage is reduced, and long-term, constant and low-cost running of the cyclotron is guaranteed.

Description

technical field [0001] The invention relates to the system design technology of a cyclotron, in particular to a circulating water system of a cyclotron and a water saving method thereof. Background technique [0002] The operation of a 100MeV cyclotron requires a large amount of high-quality circulating cooling water, and the water quality is required to be better than 0.5μs / cm. To ensure the long-term, continuous and stable operation of the accelerator, it is necessary to establish supporting deionized water production and water quality improvement devices. The production of high-quality deionized water requires multiple pretreatments (filtration, adsorption, etc.) on the raw water (tap water), and then performs multi-stage reverse osmosis desalination and purification under high pressure, and finally obtains the required purified water through the EDI process; at the same time After the circulating water passes through the accelerator power equipment, the water quality wi...

AI Technical Summary

Problems solved by technology

Given that the cyclotron is a long-term, continuous operation of high-power equipment, it will waste a lot of precious water resources if it is treated with a general process. In addition, some areas are seriously short of water, so it is even more necessary to save water.
