All-weather smoke white plume eliminating system and method based on smoke waste heat and solar complementation

Abstract

The invention relates to an all-weather smoke white plume eliminating system based on smoke waste heat and solar complementation. The all-weather smoke white plume eliminating system comprises a boiler, a desulfurizing tower, an organic Rankine cycle system, a smoke cooling system and a smoke reheating system, wherein the boiler is connected with an inlet of the desulfurizing tower through an inlet duct of the desulfurizing tower, the organic Rankine cycle system is connected to the inlet duct of the desulfurizing tower, and smoke generated by boiler combustion passes through the organic Rankine cycle system and then enters the desulfurizing tower through the inlet duct of the desulfurizing tower; an outlet of the desulfurizing tower communicates with a chimney through an outlet duct of the desulfurizing tower; and the smoke cooling system and the smoke reheating system are connected to the outlet duct of the desulfurizing tower in sequence. Three subsystems including the organic Rankine cycle system, the smoke cooling system and the smoke reheating system through smoke waste heat generation are organically and complementarily coordinated into operation, so that electric energy required for the operation of the smoke reheating system and the smoke cooling system is supplied in all weather, visual pollution caused by white smoke plume can be eliminated in all weather, additionally, water and energy are saved, and pollutants such as fine particles and the like can be coordinated to remove.

Description

technical field [0001] The invention relates to the technical field of energy and environmental protection, in particular to an all-weather flue gas white feather elimination system and method based on the complementarity of flue gas waste heat and solar energy. Background technique [0002] Common chimney white plumes (white smoke) come from many industries, including coal-fired power generation, waste power generation, biomass power generation, heating boilers and other flue gases; steel industry sintering machines, pellets, shaft furnaces, converters, hot rolling production lines flue gas; coke oven flue gas and water quenching flue gas in the coking industry; flue gas produced by glass, cement, brick and ceramic kilns; smoke produced in the production process of energy, nonferrous metals, chemical, petrochemical, building materials gas. In addition, some special industries such as PVC (polyvinyl chloride) paste resin plant drying tail gas, the tail gas components are wa...

AI Technical Summary

Problems solved by technology

[0014] In view of the characteristics of flue gas elimination of white feathers, although conventional technologies can achieve certain results, there may be shortcomings such as poor whitening effect, excessive whitening energy consumption, or inability to save water and co-manage pollutants, which is different from the current There is a certain gap between the general trend of energy saving and the new demand for environmental protection
