Spinning-type shale gas organic corrosion inhibitor atomizer

Abstract

The invention discloses a spinning-type shale gas organic corrosion inhibitor atomizer. A shell is included. A fixing mechanism, a rotating mechanism and a driving mechanism are arranged in the shell.The fixing mechanism comprises a middle roller stabilizing block. The middle roller stabilizing block is fixedly connected in the shell. An upper roller righting block is detachably installed on oneside of the middle roller stabilizing block. A lower roller righting block is detachably installed on the other side of the middle roller stabilizing block. The upper roller righting block and the lower roller righting block are detachably installed in the shell. The rotating mechanism comprises an atomizing cyclone and an impeller. The atomizing cyclone is detachably installed between the middleroller stabilizing block and the upper roller righting block. The impeller is detachably installed between the middle roller stabilizing block and the lower roller righting block, one end of the atomizing cyclone is in clearance fit with the upper roller righting block, the other end of the atomizing cyclone is detachably connected with the impeller, one end of the impeller is in clearance fit with the lower roller righting block, and the other end of the impeller is in clearance fit with the middle roller stabilizing block.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas development tools, in particular to a spin-type shale gas organic corrosion inhibitor atomizer. Background technique [0002] With the continuous development of shale gas development blocks in my country, the produced gas contains relatively high CO2, and CO2 hydrates will be ionized under high pressure and high temperature conditions, and the ionized ions will be harmful to production tools such as gathering and transportation pipelines. Larger corrosion occurs, which in turn destroys the inner wall of the gathering and transportation pipeline, causing plaque corrosion on the inner wall of the gathering and transportation pipeline, and destroying the stress structure of the gathering and transportation pipeline. When the corrosion reaches a certain level, the gathering and transportation pipeline cannot bear the pressure of the gas in the pipeline. When leaks are produced, the produced ...

AI Technical Summary

Problems solved by technology

[0003] During the research process, it was found that the current injection device has insufficient atomization during the injection process of organic corrosion inhibitors, resulting in chemical deposition, which affects the use effect of organic corrosion inhibitors and increases the amount of organic corrosion inhibitors used. The waste of organic corrosion inhibitors increases the cost of gas production. In addition, the unevenness of the organic corrosion inhibitor particles in the mixed gas results in insufficient protection of the pipe wall by the organic corrosion inhibitors, which leads to pipeline corrosion, which leads to more complicated situations and even Occurrence of pipeline rupture accidents
