Description

Desulfurization wet dedusting all-in-one machine

Technical Field

Background

In recent years, along with the increasing of installed capacity of thermal power plants and the increase of the total amount of discharged pollutants, great pressure is exerted on the atmospheric environment, and in order to implement scientific development of China, the newly issued thermal power plant pollutant discharge standard (GB13223-2011) is officially implemented in 1 month and 1 day of 2012. With the coming of new standards, people further improve the understanding of the harm of pollutants such as fine dust, acid mist, heavy metal and the like to the environment and the health, and the national emission standard of atmospheric pollutants is continuously improved. The existing wet desulphurization system has almost no capability of removing PM2.5 particles and can treat mercury and SO₃The removal of aerosol and the like is also very limited, so that the phenomena of acid rain, gypsum rain and the like frequently occur at the downstream of the wind direction of the chimney, or the phenomenon of blue smoke with long smoke tail is caused.

The first wet electric dust collector is applied to removing sulfuric acid mist all over the world as early as 1907, and the wet electric dust collector is continuously popularized to a plurality of application fields along with the continuous development of the technology. Especially, the wet-type electric dust removal technology tends to mature due to the large application in metallurgy and chemical industry. In the application of a coal-fired power plant, the wet electric dust collector can remove more than 90 percent of PM2.5 fine dust and SO₃Smoke, and can achieve almost zero turbidity emission, and can remove mercury and NH₃、SO₂And HCl, and the like. Therefore, the wet-type electric dust collector is the first choice as the terminal treatment equipment for the air pollution control of the coal-fired power plant.

However, the general desulfurization-wet electricity system has the disadvantages that the volume is huge, the occupied area is wide, the cost is increased, the water consumption of wet electricity in the application process is large, the produced chimney rain effect is serious, the corrosion to buildings near the chimney is serious, and the waste heat utilization rate in the production process is extremely low, so that the serious energy waste is caused.
