Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of manufacturing corrosion inhibition performance test equipment, in particular to a high-temperature and high-pressure reactor condensing pipeline corrosion inhibition performance evaluation test device which has a reasonable structure and reliable operation and can be used to assist in evaluating the corrosion of pipelines by high-pressure steam. Background technology:
[0002] The kettle body of the high-temperature and high-pressure reactor has a jacket layer, and a heat transfer oil coil is arranged in the jacket layer. When working, the reactants inside the kettle body are heated by the heat transfer oil coil. The heating temperature is high, and the steam generated by the heating keeps the kettle in a high-pressure state. An exhaust port is opened at the top of the high-temperature and high-pressure reactor, and the exhaust port is connected to a steam exhaust pipeline. After the steam is sent to the steam exhaust pipeline through the exhaust port, it is condensed and recycled. Since the pH value of water vapor is less than 7 under high temperature, the water vapor discharged into the steam exhaust pipeline will corrode the pipeline. In order to solve this problem, it is necessary to add corrosion inhibitors to the steam exhaust pipeline. Obviously, the amount of corrosion inhibitor added is related to the amount of steam discharged. For high-temperature and high-pressure reactor systems performing different reactions, it is necessary to adjust the amount of corrosion inhibitors added. Therefore, there is an urgent need for a test device that can facilitate accurate and reliable evaluation of the corrosion inhibition performance of the condensation pipeline of a high-temperature and high-pressure reactor.
