Abstract

The invention discloses a device for monitoring the concentration of chloride ions in reinforced concrete and automatically removing chlorine, which comprises a chloride ion concentration monitoring device and an electrochemical dechlorination device, and is characterized in that the chloride ion concentration monitoring device is used for monitoring the concentration of chloride ions in the concrete, and the electrochemical dechlorination device performs dechlorination according to the chloride ion concentration monitored by the chloride ion concentration monitoring device, and controls the concentration of the chloride ions in the concrete within a given concentration range. According to the invention, the concentration of the chloride ions in the concrete can be monitored in real time,and the chloride ion concentration is controlled within a given concentration range through the automatic dechlorination device. The device has the characteristics of being simple in structure, good in dechlorination performance, capable of being repeatedly used, low in cost and low in energy consumption.

Description

technical field [0001] The invention relates to a device for electrochemical restoration technology, in particular to a device for monitoring and automatically removing chlorine ion concentration inside reinforced concrete. Background technique [0002] Reinforced concrete is the most widely used material in contemporary buildings, bridges, water conservancy and other projects. A large number of engineering practices have shown that corrosion of steel bars in chloride environments is the primary cause of premature failure of concrete structures. Corrosion of steel bars has caused huge economic losses. loss. The intrusion of chloride ions leads to the corrosion of steel bars and the deterioration of the durability of reinforced concrete structures. Therefore, the removal of chloride ions in concrete can alleviate the corrosion of steel bars to a large extent. [0003] The electrolyte solution in the existing electrochemical dechlorination device is mostly a single alkaline e...
