Flue gas treatment device

Abstract

The invention relates to a flue gas treatment device. The flue gas treatment device comprises a flue gas oxidation unit. The flue gas oxidation unit comprises a flue gas oxidation treatment chamber connected to an oxygen supplying source and the flue gas oxidation treatment chamber is used for oxidation treatment on flue gas entering the flue gas oxidation treatment chamber. The flue gas treatment device also comprises a dedusting denitrification unit, the dedusting denitrification unit comprises a dedusting denitrification treatment chamber and a dedusting denitrification slurry circulating device for injecting dedusting denitrification slurry into the dedusting denitrification treatment chamber and recycling the dedusting denitrification slurry, and the dedusting denitrification unit is connected to the flue gas oxidation unit and is used for dedusting denitrification treatment on flue gas from the flue gas oxidation unit through the dedusting denitrification slurry. The flue gas treatment device also comprises a dedusting desulfuration unit, the dedusting desulfuration unit comprises a dedusting desulfuration treatment chamber and an alkaline slurry circulating device for injecting alkaline slurry into the dedusting desulfuration treatment chamber and recycling the alkaline slurry and the dedusting desulfuration unit is connected to the dedusting denitrification unit and is used for dedusting desulfuration treatment on flue gas from the dedusting denitrification unit through the alkaline slurry. The flue gas treatment device also comprises a steam-water separator and the steam-water separator is connected to the dedusting desulfuration unit and is used for steam-water separation treatment on flue gas from the dedusting desulfuration unit.

Description

technical field [0001] The invention relates to a flue gas treatment device. Background technique [0002] With the continuous development of industry, the various fuels used in industrial production are also increasing, especially the burning of fossil fuels and biomass fuels has become the main source of air pollution today. With the increase of air pollution in recent years, severe smog has appeared in large areas of the country. The emergence of smog not only brings many inconveniences to people's travel, but more seriously damages people's health. For this reason, the state has also formulated many measures for the control and prevention of environmental pollution, and proposed emission standards for substances such as nitrogen oxides, sulfur dioxide, and dust. [0003] In order to reduce pollution, circulating fluidized bed boiler technology is a high-efficiency, low-pollution and clean combustion technology that has developed rapidly in the past ten years.
