Abstract
The invention relates to a performance evaluation device for a seawater desalination water treatment agent, and the performance evaluation device is composed of a corrosion weight loss and calcium carbonate deposition test system, a vacuum adjustment system and a temperature adjustment system, wherein a vacuum experiment box is set in the device, the corrosion weight loss and calcium carbonate deposition test system is integrated in the vacuum experiment box, the working temperature and negative pressure conditions of low-temperature multi-effect seawater desalination can be simulated in the box, and the temperature and pressure stability during the experiment can be maintained through an auxiliary system. The performance evaluation device provided by the invention can reduce the temperature and pressure conditions applied by the low-temperature multi-effect seawater desalination water treatment agent in the laboratory to the greatest extent, and perform in-situ, synchronous and comprehensive evaluation of its corrosion inhibition or scale inhibition performance under these conditions, thereby effectively improving the accuracy and convenience in the evaluation of corrosion and scale inhibition performance of water treatment agents in the field.
Description
technical field [0001] The invention relates to a simulation device for performance evaluation of a seawater desalination water treatment agent, in particular to an evaluation device for corrosion and scale inhibition performance of a water treatment agent for simulating low-temperature multi-effect seawater desalination conditions. Background technique [0002] With the continuous deepening of my country's industrialization and urbanization, the shortage of fresh water resources has become a key factor restricting economic development. Seawater desalination is one of the effective open-source means to solve the scarcity of freshwater resources from the source. Among them, low-temperature multi-effect distillation seawater desalination technology has attracted extensive attention from academia and engineering circles due to its advantages such as low power consumption, high thermal efficiency, safe and reliable system operation, and high purity of product water. [0003] As...
