AI Technical Summary

Technical Problem

Existing magnetic pumps used in fluorinated tail gas absorption devices are prone to corrosion at the bottom of the isolation sleeve, leading to perforation and gas leakage, which affects the operation of the device and causes environmental pollution.

Method used

A first baffle and diffuser are installed in the magnetic pump to prevent the formation of the cyclone or weaken its intensity. Multiple baffles are installed on the bottom wall of the isolation sleeve to prevent the rotation of the cyclone. At the same time, an anti-corrosion layer is applied to the inner wall of the isolation sleeve to improve the corrosion resistance of the structure.

Benefits of technology

It effectively extends the service life of the isolation sleeve, improves the reliability of the magnetic pump, reduces gas leakage, and extends the service life of the magnetic pump.

Abstract

This application discloses a magnetic pump, including a magnetic sleeve, an inner magnetic rotor, a first baffle, and a diffuser. The first baffle is disposed at the center of the bottom wall of the sleeve and has a first plane parallel to the axial and radial directions of the sleeve. The diffuser is disposed at the end of the inner magnetic rotor near the bottom wall of the sleeve and at the center of the inner magnetic rotor. The diffuser guides gas to diffuse toward the side wall of the sleeve. During the rotation of the inner magnetic rotor, the diffuser guides the airflow toward the side wall of the magnetic sleeve, hindering the formation of cyclones or weakening the intensity of the cyclones. Simultaneously, the first baffle on the bottom wall of the sleeve causes the formed cyclones to impact the first plane of the first baffle, thereby hindering the rotation of the cyclones. This effectively reduces the corrosion of the bottom wall of the sleeve by the cyclones, extends the service life of the sleeve, and improves the reliability of the magnetic pump. This application also discloses a tail gas absorption device and a bis(fluorosulfonyl)imide preparation system.
