AI Technical Summary

Technical Problem

Existing natural gas drag-reducing agents have poor adhesion after atomization, and the film is prone to falling off, leading to pipeline blockage. Furthermore, existing devices have failed to effectively evaluate the drag-reducing effect.

Method used

Design a natural gas drag-reducing agent atomization injection indoor circulation system, including a shell, a conical jet cylinder, a gas-liquid mixing chamber and a throttling orifice plate. The drag-reducing agent is uniformly attached through atomization and magnetic field action, and the drag-reducing efficiency is evaluated by combining pressure difference and flow rate changes.

Benefits of technology

It improves the adhesion of drag-reducing agents in pipelines, reduces resistance and friction, extends the life of pipeline equipment, lowers maintenance costs, and enables accurate evaluation of drag-reduction effects.

Abstract

The application relates to the field of turbulent flow control in fluid mechanics and discloses a natural gas drag-reducing agent atomization injection indoor circulation system. The system is composed of a natural gas drag-reducing agent atomization device and an indoor circulation pipeline; the natural gas drag-reducing agent atomization device comprises a shell, a conical jet cylinder and a gas-liquid mixing cavity; a conical jet cylinder and a nozzle are arranged in the shell; the nozzle can be automatically adjusted within an angle range of 20-80 degrees according to the natural gas conveying flow; a blade support plate cuts the mixed drag-reducing agent to atomize the drag-reducing agent again; the particle size of the atomized drag-reducing agent ranges from 20 to 40 microns; square magnet blocks are evenly arranged on the outer wall of the indoor circulation pipeline; the number of the square magnet blocks is 114; the length of each square magnet block is 200 mm, the width is 80 mm, and the thickness is 50 mm. The application utilizes the comprehensive effect of jet flow, cutting and electromagnetic field to enhance the atomization and adhesion effect of the drag-reducing agent; the drag-reducing effect of the drag-reducing agent atomization injection is evaluated based on control variables; and the result can be applied to the drag-reducing conveying of a natural gas long-distance pipeline.
