The invention relates to a forced current cathodic protection device of a degreaser. The forced current cathodic protection device comprises auxiliary anodes and a DC power supply, wherein the auxiliary anodes are arranged in an inner cavity of the degreaser and can make contact with liquid in the inner cavity; the positive pole of the DC power supply is connected with the auxiliary anodes, and the negative pole of the DC power supply is connected with the metal cavity wall and a metal component of the inner cavity of the degreaser. Under the action of the DC power supply, the metal cavity wall of the inner cavity of the degreaser has a reducing reaction, and the auxiliary anodes have an oxidizing reaction. The forced current cathodic protection device can more effectively prevent the metal cavity wall of the inner cavity of the degreaser from being corroded, so that the protection effect of the degreaser is enhanced.
Description
technical field [0001] The invention belongs to the field of oil field exploitation equipment, and in particular relates to a forced current cathodic protection device for an oil remover. Background technique [0002] The degreaser is one of the important equipment in the oil, gas and water gathering and transportation treatment process of oilfield development. Due to its complex internal structure, the medium to be treated is highly corrosive, and the working conditions vary greatly. Under the joint action of mechanics and complex electrochemical corrosion, The metal cavity walls of its inner cavity can be corroded so as to seriously shorten the service life of the degreaser. If the corrosion failure of the degreaser occurs frequently, the function of the degreaser cannot be effectively performed. The leakage of air, gas and water will affect the safe production and operation and bring hidden dangers of environmental pollution. At the same time, frequent maintenance of the...
