Truss type sacrificial anode protection device of double-cylinder horizontal metering separator

Abstract

The invention discloses a truss type sacrificial anode protection device of a double-cylinder horizontal metering separator. The truss type sacrificial anode protection device comprises a plurality oftrusses which are arranged in a lower tank body of a double-cylinder horizontal metering separator; the top of each truss is connected with an upper rack; the bottom of each truss is connected with alower rack; a plurality of elastic kinematic-seal contact point systems which can have close contact with the top of the inner wall of the lower tank body of the double-cylinder horizontal metering separator are uniformly distributed at the upper part of the upper rack; a plurality of rolling wheel systems which can have close contact with the bottom of the inner wall of the lower tank body of the double-cylinder horizontal metering separator are uniformly distributed at the bottom of the lower rack; the middle parts of the trusses are connected by screws which can be used for controlling thelift of the trusses; the screws are fixedly provided with a plurality of sacrificial anodes; the sacrificial anodes correspond to the trusses one by one; and each sacrificial anode is arranged at theinner side of the corresponding truss. When the truss type sacrificial anode protection device disclosed by the invention is used, the protection current is uniformly distributed; the inside of the tank body can be completely covered; and meanwhile the sacrificial anodes are convenient to replace.

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.
