System and method for treating white smoke plume of desulfurization flue gas

Abstract

The invention provides a system and a method for treating white smoke plume of a desulfurization flue gas. According to the system and the method, by virtue of the characteristic that a great deal ofsensible heat and latent heat is released when a high-temperature saturated purified flue gas is cooled and condensed, low-temperature waste heat recycling is achieved by using a compression type heatpump, through refrigerant circulation, low-level heat is promoted into high-level heat, the high-temperature saturated purified flue gas is reheated into a high-temperature unsaturated purified fluegas, a great deal of condensation water is extracted from the desulfurization flue gas, secondary desorption of multiple pollutants such as fume dust and sulfur dioxide is promoted, low-temperature waste heat is recycled by using a heat pump technique, 'white smoke plume' is eliminated, the view effect of flue gas emission is improved, and triple purposes of water conservation, energy conservationand'white plume' treatment are achieved.

AI Technical Summary

Benefits of technology

This patented method uses an air compressor that works on compressed hot gases from a boiler to reclaim moisture while also making it easier to remove any remaining ash particles by allowing them to pass through another device called a filter before being returned into the furnace again. By doing this, the amount of harmful emissions produced when burning fossil fuels becomes less than what was previously possible due to combustion processes used without exhaust purification devices such as filters. Additionally, the method allows for efficient recovery of waste heat generated within industrial facilities like power plants. Overall, these improvements make the methods more cost-effective and effective treatments for pollution control issues.

Problems solved by technology

This patents describes various technical methods described during combustion processes like burning fossil fuels to remove harmful substances including sulfur oxides, nitrosoxygen compounds, particulate matter, etc., while minimizing loss of valuable resources. These techniques include dry scrubbing systems where the exhaust gases pass over packings containing activated carbon powders called absorbents, cooled mist separators, and filters. Additionally, these techniques involve removing humidity from the flues before they exit into the atmosphere without causing significant negative impact upon both indoor environments and public health concerns.
