Problems solved by technology

[0004] Due to the viscosity of petroleum products and weak electrochemical response, ordinary electrodes are not suitable for measuring the electrical parameters of high-temperature and high-pressure petroleum. At present, there are no high-temperature and high-pressure electrodes suitable for the petroleum industry, and it is impossible to realize the electrical parameters of petroleum processing. Online direct measurement of

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] An electrode for a high-temperature and high-pressure reactor, including an electrode bracket, an electrode plate, and an electrode terminal 16. The electrode bracket is installed in the reactor, the electrode plate is installed on the electrode bracket, and the electrode plate is fixed firmly. No shaking, the electrode plate includes the left electrode 14 and the right electrode 15. Due to the high requirements on the conductivity, high temperature resistance and high pressure resistance of the material in the reactor, it needs to withstand the high temperature of 500 ℃ and the high pressure of 25MPa, and at the same time To resist the erosion of reactive gases such as hydrogen and nitrogen, the electrode plates are made of stainless steel, copper, aluminum and other materials. There are two electrode terminals 16, which are installed on the lid of th...

Abstract

The invention relates to a high-temperature and high-pressure reaction kettle electrode. The high-temperature and high-pressure reaction kettle electrode is characterized by comprising an electrode bracket, an electrode pad and two electrode wiring terminals, wherein the electrode bracket is arranged in a reaction kettle; the electrode pad comprises a left electrode and a right electrode and is arranged on the electrode bracket; the two electrode wiring terminals are arranged on a cover of the reaction kettle; each electrode wiring terminal comprises a terminal body; an upper pole is arranged at the upper part of each terminal body; a lower pole is arranged at the lower part of each terminal body; the lower poles of the two electrode wiring terminals are connected with the left electrode and the right electrode on the electrode pad respectively. The invention also provides an on-line monitoring method with the high-temperature and high-pressure reaction kettle electrode. Under the cooperation of the high-temperature and high-pressure reaction kettle electrode and instruments such as an electrophoresis instrument and a conductivity meter, electrical parameters in scientific research and production processes of petroleum and petrochemicals can be measured on line.

Description

technical field [0001] The invention relates to the technical field of electrical measurement, in particular to a high-temperature and high-pressure reactor electrode for on-line monitoring of system electrical signals during petrochemical production and scientific research, and an on-line monitoring method using the electrode. Background technique [0002] In the petrochemical scientific research and production process, the electrical parameters of the system, such as electrical conductivity and dielectric constant, are important measurement parameters. The current existing devices are difficult to realize online testing of the reaction system under high temperature and high pressure. When the sample is tested at room temperature and atmospheric pressure, the electrical parameters of the system will have a large deviation from the value under high temperature and high pressure; moreover, the electrical parameters in the reaction process can be measured online, and the elect...
