Natural gas purifying, collecting and conveying pipeline

Abstract

The invention discloses a natural gas purifying, collecting and conveying pipeline. The natural gas purifying, collecting and conveying pipeline comprises a gas collecting pipe body, a heating pipe body, a dedusting pipe body and a purifying pipe body which are sequentially and detachably connected in a sealing way; a coarse filtering net is arranged at a gas inlet of the gas collecting pipe body,an air suction fan is arranged in the gas collecting pipe body, an air inlet of the air suction fan is communicated with a gas inlet of the gas collecting pipe body, and an air outlet of the air suction fan is communicated with a gas inlet of the heating pipe body; a heater is arranged in the heating pipe body; a deduster is arranged in the dedusting pipe body; the purifying pipe body comprises afirst purifying pipe body, a second purifying body and a third purifying pipe body which are sequentially and detachably connected in a sealing way; a spraying system is arranged at the top part of the interior of the first purifying pipe body; an acid gas molecular sieve filler is arranged in the second purifying pipe body; a water steam molecular sieve filler is arranged in the third purifyingpipe body. The natural gas purifying, collecting and conveying pipeline has the advantages that the natural gas can be purified at high efficiency, the generation of hydrate of natural gas is avoided,the blockage and corrosion of the natural gas conveying pipeline are reduced, and the maintenance and replacement are convenient.

Description

technical field [0001] The invention relates to the technical field of natural gas processing gathering and transportation pipelines, in particular to a natural gas purification gathering and transportation pipeline. Background technique [0002] As a naturally occurring gas, natural gas can be natural gas formed from the atmosphere, lithosphere, and hydrosphere. It is a general term for a type of mixed gas mainly composed of hydrocarbons. , Tasteless, non-toxic characteristics. The main components of natural gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane, and butane. In addition, there are generally hydrogen sulfide, carbon dioxide, nitrogen, water vapor, a small amount of carbon monoxide, and trace amounts of rare gases, such as helium and argon. . Natural gas is mainly used as fuel, and is also an important chemical raw material, which can be used in pharmaceutical manufacturing, chemical material manufacturing, a...

Problems solved by technology

The moisture and sulfur-containing substances in it will seriously corrode the pipeline. After a long period of corrosion and oxidation, pipeline leakage will easily occur, which will pose a great safety hazard.

At the same time, the pipeline needs to be replaced in time, which is costly and requires a large amount of work
