AI Technical Summary

Technical Problem

The prior art is difficult to effectively remove SO2 and dust in the flue gas of the thermally regenerative heating furnace, resulting in the emissions not meeting the standards and the ultra-low emission requirements cannot be met.

Method used

A desulfurization and dust removal device is arranged between the smoke exhaust port and the chimney of the thermal storage heating furnace, including a desulfurization dust collector and a desulfurization fan. The activated calcium desulfurization agent is sprayed in full contact with the flue gas, absorbs SO2, and removes dust through a dust removal bag.

Benefits of technology

It realizes effective desulfurization and dust removal of flue gas of the thermally regenerated heating furnace, removes SO2 and dust, so that the treated flue gas meets ultra-low emission requirements.

Abstract

The present invention provides a desulfurization and dust removal process for a regenerative heating furnace. A desulfurization and dust removal device is arranged between a smoke outlet of the regenerative heating furnace and a chimney for discharging standard flue gas. The desulfurization and dust removal device comprises a desulfurization dust collector and a desulfurization induced draft fan. The smoke outlet of the regenerative heating furnace is connected to an inlet flue of the desulfurization dust collector, and the exhaust port of the desulfurization dust collector is connected to the chimney through the desulfurization induced draft fan. When the flue gas discharged from the regenerative heating furnace enters the inlet flue of the desulfurization dust collector through the smoke outlet, a desulfurizer is sprayed into the inlet flue of the desulfurization dust collector, so that the desulfurizer is fully in contact with the flue gas in the inlet flue, thereby SO 2 The flue gas after desulfurization enters the dust bag of the desulfurization dust collector for dust removal; the flue gas after dust removal is sent into the chimney through the desulfurization induced draft fan and discharged into the atmosphere. The technical solution of the present invention realizes the desulfurization and dust removal at the end of the regenerative heating furnace, ensuring that the heating furnace meets environmental protection requirements for production.
