Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of corrosion inhibitor production, in particular to a corrosion inhibitor emptying and drainage device. Background Art
[0002] Corrosion inhibitors are chemical substances or compounds that, when present in an environment (medium) at appropriate concentrations and forms, can prevent or slow down the corrosion of materials. Therefore, corrosion inhibitors can also be called corrosion inhibitors. They are used in very small amounts (0.1% to 1%), but their effects are significant. This method of protecting metals is called corrosion inhibitor protection. Corrosion inhibitors are used in neutral media (boiler water, circulating cooling water), acidic media (hydrochloric acid for descaling, acid immersion solutions for rust removal before electroplating), and gaseous media (vapor-phase corrosion inhibitors). Generally speaking, corrosion inhibitors are substances that act as a protective agent on metal surfaces. Adding trace or small amounts of these chemicals can significantly reduce the corrosion rate of metal materials in the medium, down to zero. At the same time, the original physical and mechanical properties of the metal material remain unchanged. The rational use of corrosion inhibitors is an effective method for preventing the corrosion of metals and their alloys in environmental media. Corrosion inhibitor technology has become one of the most widely used methods in corrosion prevention technology due to its excellent effectiveness and high economic benefits. Especially in the production and processing of petroleum products, chemical cleaning, atmospheric environment, industrial water, machinery, instrument manufacturing and petrochemical production, corrosion inhibition technology has become one of the main anti-corrosion means.
[0003] Various pipelines are used in the production well station process of oil and gas fields. After long-term use, the pipelines need to be flushed with corrosion inhibitors to slow down the aging rate of the pipelines. After cleaning the pipelines, the corrosion inhibitors are usually directly discharged through the drain port on the pipelines. Most corrosion inhibitors can still be used after cleaning the pipelines. Direct discharge causes a large amount of corrosion inhibitor waste, which is not conducive to the control of production costs. Based on this, the present application proposes a corrosion inhibitor emptying and drainage device to solve the above problems. Utility Model Content
