Abstract

The invention relates to an atmospheric environment corrosion testing device for a high sulfur natural gas purification plant, which is mainly for solving the problems that an atmosphere corrosion exposure test is long in period and low in speed, and electrochemical test data has large difference with actual condition in the prior art. The atmospheric environment corrosion testing device for the high sulfur natural gas purification plant comprises a zero-resistance galvanometer (1), a fixing bracket (2), a zero-gravity test block (3), a double-electrode primary battery anode strip (4), an insulating bolt (5), an insulating layer (6), a double-electrode primary battery cathode strip (7), an insulating diagram (8) and electrode leading-out ends (9), wherein the electrode leading-out ends (9) are respectively led out from the double-electrode primary battery anode strip (4) and the double-electrode primary battery cathode strip (7), and the electrode leading-out ends (9) are connected with the zero-resistance galvanometer (1) through lead wires, so that a double-electrode primary battery is integrally formed. By adopting the technical scheme, the problems can be well solved, and the atmospheric environment corrosion testing device can be applied to the atmospheric environment corrosion test for the high sulfur natural gas purification plant.

Description

technical field [0001] The invention relates to an atmospheric environment corrosion testing device for a high-sulfur natural gas purification plant. technical background [0002] With the increasing shortage of energy and the increasing demand for energy, especially for green energy natural gas, my country has begun the development and utilization of high-sulfur-containing gas fields. In the future, the development and utilization of high-sulfur natural gas will be an New benefit growth points and development trends. [0003] In the atmospheric environment of a high-sulfur natural gas purification plant, SO 2 , SO 3 、H 2 The high content of S causes severe atmospheric corrosion of the steel structure of the device, the body of the equipment and instrumentation, and the surface of the control room. It can be seen that it is of great practical significance to develop an atmospheric corrosion test device for the air pollution environment of high-sulfur natural gas purificat...
