High-activity sea sand desalination dechlorinating agent preparation device and high-activity sea sand desalination dechlorinating agent preparation method

Abstract

The invention discloses a device and a method for preparing a high-activity sea sand desalination dechlorinating agent. The device comprises a fresh water input interface, a booster pump is mounted onthe outer side of the fresh water input interface; the other side of a nano activator is connected with a mixing pump through an activator conveying pipe, a mixing tower is installed on the side of the mixing pump, an overflowing gas reducer is arranged at the top of the mixing tower, the mixing tower is connected with an ozone generator through an ozone conveying pipe, and an ozone content monitoring device is installed on the side of the mixing tower. According to the high-activity sea sand desalination dechlorinating agent preparation device and the method, high-activity sea sand dechlorinating agent is completely feasible to replace fresh water used for traditional sea sand desalination such as a soaking method or a flushing method, the desalination time is short, the dechlorinating performance is excellent, cooperation with a sea sand desalination machine and a cycling water recycling system is adopted, the sea sand desalination speed can be greatly increased, fresh water resources are saved, the ecological environment is not damaged, the efficiency is higher, and the method is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of sea sand desalination, in particular to a preparation device and method for a highly active sea sand desalination dechlorination agent. Background technique [0002] Since sea sand contains a certain amount of chloride ions, using sea sand to make concrete to pour buildings will cause the steel bars in the concrete to be corroded and oxidized by the chloride ions infiltrated by sea sand, which will easily cause the strength, hardness and bearing capacity of the building to decrease, seriously affecting the useful life of the building. Therefore, the effective removal of chloride ions is the key to sea sand desalination, among which sea sand freshwater immersion method and fresh water washing method are the most commonly used methods. [0003] However, the fresh water immersion method needs to soak the sea sand for a long time, occupies a large area, and has low utilization rate of fresh water resources; ...
