Full-drift-diameter pipeline type sand remover

Abstract

The invention discloses a full-drift-diameter pipeline type sand remover. An inlet three-way pipe, a full-drift-diameter pipe cleaning valve, a spiral sand removal section, a flow direction adjustingoutlet, a bypass connecting pipe, a full-drift-diameter ball valve and a sand storage chamber are included. The inlet three-way pipe is composed of a three-way main pipe and a three-way branch pipe. The spiral sand removal section is formed through mutual nesting of a spiral sand removal section inner barrel and a spiral sand removal section outer barrel. The flow direction adjusting outlet is formed through mutual nesting of a flow direction adjusting inner barrel and a flow direction adjusting outer barrel. The three-way main pipe communicates with the spiral sand removal section inner barrel. The spiral sand removal section inner barrel communicates with the flow direction adjusting inner barrel. The spiral sand removal section outer barrel communicates with the flow direction adjustingouter barrel. The bypass connecting pipe communicates with the three-way branch pipe and a branch pipe inlet. A spiral blade is arranged in annular space between the spiral flow sand removal sectionouter barrel and the spiral flow sand removal section inner barrel. The position, below the spiral blade, of the bottom of the spiral flow sand removal section outer barrel is provided with a row of sand discharging ports, and the sand discharging ports serve as openings for solid-liquid impurities to enter the sand storage chamber. By usage of the full-drift-diameter pipeline type sand remover, solid impurities in oil gas can be efficiently separated out, and normal conveying of pipelines is not influenced in the sand cleaning process.

Description

technical field [0001] The invention belongs to the technical field of centrifugal separation and flow guarantee, and relates to a full-diameter pipeline type desander. Background technique [0002] The characteristics of natural gas determine that natural gas pipeline transportation is more economical and reliable than other transportation methods, and it is currently the main method of onshore natural gas transportation. The main sources of liquid and solid impurities in the natural gas transmission system include: condensate oil, condensate water, and cuttings dust brought downhole during gas production; dirt and residue left during pipeline construction; iron filings and corrosion products in the pipeline . [0003] Dust particles such as sand and rust move with the high-speed air flow, which will cause strong abrasion to the inner wall of the pipeline. As the main power equipment in the gas transmission process, the compressor has strict requirements on the content of ...
