Method and device for purifying flue gas and controlling smoke plume

Abstract

The invention provides a method and a device for purifying flue gas and controlling smoke plume. The flue gas is deeply purified and the white smoke plume is treated. The device comprises a heterogeneous coring agglomeration reaction system, a flue gas deep purifying system, a flue gas warming reaction system and a heat pump cycling system which are successively arranged along the flowing direction of the flue gas; the heat pump cycling system is connected with the heterogeneous coring agglomeration reaction system and the flue gas warming reaction system through a pipeline; the flue gas is purified by the heterogeneous coring agglomeration reaction system; the flue gas enters the flue gas deep purifying system for further removing fine particulate matters; the flue gas after being deeply purified is heated by the flue gas warming reaction system and then is discharged; the flue gas heat absorbed by the heterogeneous coring agglomeration reaction system exchanges heat with a cooling medium of a heat pump system; a heating medium after being heated is used for increasing the temperature of the flue gas of the flue gas warming reaction system.

Description

technical field [0001] The invention relates to a flue gas purification and plume control method and device based on nucleation agglomeration and heat pump heating, belonging to the field of environmental protection. Background technique [0002] In recent years, the problem of haze in winter has become very prominent. Among the haze in the atmosphere, the actual source of direct emissions and secondary conversion is related to coal-burning emissions. In the prevention and control of the source, in addition to controlling the direct pollutants of coal, the secondary pollutants brought about by the denitrification and desulfurization process should also be taken into account. In terms of composition, in addition to organic pollutants (OM), haze is mainly soluble salts such as nitrates and sulfates. In terms of sources, secondary conversion accounts for a large proportion in the formation of haze, and has a large impact on PM2 .5 and organic aerosol particulate matter contr...

Problems solved by technology

[0005] As far as the current ultra-low emission technology routes are concerned, most of them are gradually developed and perfected in the exploration of technical practice. Although the synergistic removal of condensable pollutants has attracted attention, the mechanism of synergistic removal is still unclear

At the same time, the dust and fog removal technology also faces many challenges such as simplifying (or integrating) the process and reducing energy consumption per unit of flue gas treatment.
