Problems solved by technology

[0004] However, in the existing reactors, corrosion will not appear until the test pipes are soaked in the corrosion inhibitor for at least three days, and it takes a long time to obtain accurate corrosion information. The corrosion condition of the pipe can only be observed when it is taken out. Therefore, the existing reaction kettle cannot quickly and easily obtain the corrosion resistance of the test pipe and the corrosion inhibition performance of the corrosion inhibitor.

Abstract

The invention provides a reaction vessel and a corrosion testing system. the reaction vessel comprises a heating device, a vessel body arranged in the heating device, a vessel cover for sealing the vessel body, a tension shaft which passes through the vessel cover and is inserted into the vessel body, a transmission gear connected with the tension shaft, and a three-electrode system. The three-electrode system comprises a working electrode, a reference electrode and an auxiliary electrode. The vessel cover is provided with a first electrode port and a second electrode port. The reference electrode is inserted into the vessel body through the first electrode port. The auxiliary electrode is inserted into the vessel body through the second electrode port. The work electrode is arranged at one end of the tension shaft, one end of which is the end positioned inside the vessel body. The inside of the tension shaft is a hollow structure.

Description

technical field [0001] The invention relates to the technical field of chemical instruments, in particular to a reaction kettle and a corrosion test system. Background technique [0002] Reactor, broadly understood as a container for physical or chemical reactions, specifically, refers to the structural design and parameter configuration of the container according to the requirements of different process conditions, in order to achieve the mixing functions of heating, evaporation, and cooling required by the process. It is used in the research of various scientific experiment projects such as petroleum and chemical industry. Generally speaking, the reactor is mainly used in the oil field for corrosion tests in oil and gas fields, mainly to evaluate the corrosion resistance of various pipes and the corrosion inhibition performance of corrosion inhibitors. [0003] Existing reactors used for corrosion tests in oil and gas fields are mainly tested by rotating coupons in the re...
