The reporter visited the thermal power plant that was so clean here!

The floor of the thermal power plant is cleaned like a mirror.

The dust in the workshop is not dyed, the ground floor is clean, and there is no coal dust in the air ... Is this really a hot power plant?

On August 26, Qinhuangdao Power Generation Co., Ltd., also known as the hot power plant familiar to Qinhuangdao people, held an open day event to invite citizens and media to visit the factory. Explain the principles and processes of thermal power plants, thermal production principles and processes, and visit the photovoltaic project running control rooms and factory area ... The whole process leaves the most impressive impression on reporters: clean!

In people's traditional cognition, coal -fired power generation emissions and pollution are high, and they belong to non -clean energy. But walking into the door of the thermal power plant, the perception of the visiting team was repeatedly refreshed. Isn't the heat power plant burning coal power generation? How can a little coal and dust in the factory area disappear? Then walk into the outdoor workshop, the ground is as clean as a mirror. The staff couldn't help laughing: "We have closed the coal yard the year before yesterday." Not only the coal yard, the staff said to show that the turning machine and the ash slag warehouse were closed, eliminating the rollover rollover, and the rollover ruming was eliminated. Eat emissions and dust during the ash removal period.

The staff told everyone that not only the dust of coal that was visible to the naked eye was gone. After continuous environmental protection transformation for so many years, the thermal power plant was close to zero emissions. Facing the requirements of the country's strict control of environmental protection indicators and strict control of emission standards, new technologies, new equipment, and new processes of thermal power plants have been applied to accelerate the upgrading of old units of desulfurization, denitration and dust removal technology. At present, the four coal -fired units have all completed dust removal, desulfurization, denitrification efficiency and renovation, and no organizational discharge governance. The construction rate of environmental protection devices has reached 100%. After the reconstruction, the concentration of sulfur dioxide emissions drops from 200 mg/ m3 to below 25mg/ m3, the concentration of nitrogen oxide is reduced from 200 mg/ m3 to less than 30mg/ m3, and the concentration of smoke and dust emission is dropped from 20mg/ m3 to below 5mg/ m3. The concentration of air pollutants discharge reaches the requirements of the "Deep Treatment Emissions Emissions Emissions" of the Hebei Provincial Coal -fired Power Plant, and all pollutants such as sewage and industrial solid waste meet the current environmental protection standards.

At the same time, the thermal power plant also recovered the clean water such as fixed drainage and drainage of boilers, electric removal with hot and cold water, etc. to maximize the use of recycling water and reuse to achieve zero discharge of wastewater. Three major transformation tasks. It is through more than ten years of environmental transformation and improvement that we can see such a clean heat power plant today.
