AI Technical Summary

Technical Problem

The cyclone dust collector has low efficiency in removing fine particles (especially PM2.5), and the deposition particles are difficult to clean, which poses a risk of secondary entrainment.

Method used

The condensation-strengthening electrostatic cyclone dust collector is used to condense the wet flue gas through a condensation tube, promote the condensation of water vapor on the surface of fine particles, increase the particle size, and mix the electrostatic atomization nozzle with charged water mist to further improve the removal efficiency of fine particles.

Benefits of technology

The removal efficiency of fine particles is significantly improved, efficient capture of fine particles is achieved, and the self-cleaning mechanism of the condensate film is avoided and the risk of secondary entrainment is reduced.

Abstract

The invention relates to a condensation strengthening type electrostatic cyclone dust collector which comprises a cylinder box body, a conical cylinder box body and a dust storage container which are sequentially communicated downwards in a sealed mode, a discharge electrode extends to the position above an inlet of the dust storage container, and an electrostatic atomizing nozzle is installed above the inlet of the dust storage container and right faces the discharge electrode. The electrostatic atomizing nozzle is connected to the outside of the dust storage container through a pipeline, a condenser pipe inlet and a condenser pipe outlet are formed in the periphery of the smoke outlet pipe on the port plate, the condenser pipe which is spirally wound into a solenoid shape is placed in the cylindrical box body next to the vertical pipe, and the bottom of the condenser pipe extends to the bottom of the discharge electrode. The water inlet end of the condensation pipe extends out of the condensation pipe inlet, and the water outlet end of the condensation pipe extends out of the condensation pipe outlet. Cyclone dust removal, electrostatic dust removal, condensation dust removal and electrostatic spraying dust removal are integrated, and multiple kinds of work do not affect one another.
