A sacrificial anode protection device for a truss-type double-tube horizontal metering separator

Abstract

The invention discloses a sacrificial anode protection device for a truss-type double-tube horizontal metering separator, which comprises several trusses arranged in the lower tank body of the double-barrel horizontal metering separator, and the top of each truss is connected with an upper platform, The bottom is connected with the lower platform, and the upper part of the upper platform is evenly distributed with a number of elastic dynamic sealing contact systems that can be in close contact with the top of the inner wall of the lower tank of the double-tube horizontal metering separator. The roller system closely contacts the bottom of the inner wall of the lower tank of the double-barrel horizontal metering separator. The middle parts of several trusses are connected by a screw that can control the lifting of the truss. Several sacrificial anodes are fixed on the screw, and the sacrificial anodes correspond to the trusses one by one. , and the sacrificial anode is arranged on the inner side of the corresponding truss. When the invention is used, the protection current is evenly distributed, and the inside of the tank body can be completely covered, and at the same time, the replacement of the sacrificial anode is convenient.

Description

technical field [0001] The invention relates to the technical field of corrosion protection for natural gas mining and transportation equipment, in particular to a corrosion protection device for a double-barrel horizontal metering separator with a blind plate-type liquid collecting head, in particular to a truss-type double-barrel horizontal metering separator Sacrificial anode protection. Background technique [0002] Natural gas buried underground is in the state of condensate gas. After it is extracted from the wellhead of the gas well without dehydration and dehydrocarbon treatment, it will contain a small amount of condensate oil, condensate water, and saturated water vapor. The liquid holdup rate is high, and it is wet natural gas. . Wet gas is transported through pipelines to various gas gathering stations for metering and preliminary dehydration treatment, and then transported through pipelines to purification plants or treatment plants for "deep processing", makin...

Problems solved by technology

[0004] In view of the above technical problems, the present invention provides a sacrificial anode protection device for a truss-type double-barrel horizontal metering separator, which has a uniform protection current distribution and can fully cover the inside of the tank. Uneven current distribution, unprotected or underprotected at one end of the blind plate, sacrificial anode support cannot be reused, etc.
