Abstract

The invention provides a water-soluble acid-base testing device and a water-soluble acid-base testing method. The bottom end of an extracting container in the testing device is communicated with a funnel via a first liquid charge pipe; the first liquid charge pipe is provided with a first flow meter and a first electromagnetic valve; an indicator bottle is communicated with the funnel via a second liquid charge pipe; the second liquid charge pipe is provided with a second flow meter and a second electromagnetic valve. According to the testing device, by the arrangement, an extracting phase at the lower layer and an indicator respectively fall into the funnel continuously under the respective gravity, so that the extracting phase and the indicator are uniformly mixed on the bottom of the funnel. Therefore, the testing device overcomes the defects that the existing water-soluble acid-base testing device adopts many components and is difficult to assemble, and has the characteristics of simple structure, and convenience in use and maintenance.

Description

technical field [0001] The invention relates to an acid-base test device and a test method, in particular to a test device and a test method capable of automatically detecting the water-soluble acid-base content in oil products, and belongs to the technical field of test equipment. technical background [0002] The water-soluble acids and bases of petroleum products are mostly water-soluble mineral acids or bases formed from uncleaned residues in the acid-base refining process of petroleum fractions. Among them, the mineral acids are mainly sulfuric acid and its derivatives. Including sulfonic acid and acidic sulfate ester, the mineral bases are mainly caustic soda and sodium carbonate. During the production, use or storage of oil products, these water-soluble acids and bases will corrode the metal components in contact with them on the one hand, and the water-soluble alkalis will only corrode aluminum. However, water-soluble acid has a strong corrosive effect on almost all...
