"Sulfur dioxide, nitrogen oxides, soot, the emission targets far below the national standards for coal-fired units." Recently, Huaneng Luoyang Thermal Power Co., Ltd. plant in front of the plant, the company's environmental engineer Lvzhankai pointing to the screen beating figures Say.
The company's large-screen real-time monitoring data at the door show: 2 sets of 350,000 kilowatts coal-fired units, each of the standard cubic meters of sulfur dioxide emissions of 20.36 mg, 24.15 mg of nitrogen oxides, smoke and dust 2.18 mg.
According to reports, the company adopted advanced flue gas synergistic treatment of environmental technology, the concentration of sulfur dioxide, nitrogen oxides and soot were lower than 35 mg per cubic meter, 50 mg and 4.75 mg of emission standards. Compared with ordinary coal-fired units, the two units equipped with flue gas desulfurization, denitration and high-efficiency dust removal facilities reduce emissions of about 165 tons of dust, about 275 tons of sulfur dioxide and about 550 tons of nitrogen oxides each year. In addition, all the water used in the project will be supplied by the municipal water plant, which will be supplied by Jianxi Sewage Treatment Plant, so that the wastewater can be effectively recycled and a virtuous cycle of aquatic ecology can be realized.
"On the basis of conventional treatment, we implement secondary desulfurization and other technologies to improve the desulfurization efficiency." Lu Zhaokai pointed to the desulfurization tower, said the installation of wet electrostatic precipitator in the upper desulfurization tower, the application of electrostatic principle can effectively remove the dust in the exhaust gas, Acid mist, aerosols and other harmful substances. "After the implementation of the ultra-low-emission flue gas reform, coal-fired units can reach the emission level of gas-fired units and coal can be cleaned like natural gas."
Reporters on the scene saw the power plant did not imagine the soot flying and smoke billowing, almost can not hear the sound of the machine, only a dozen-story chimney constantly "spit" with white water vapor. Building white buildings wrapped in generators, transformers, power lines, boilers and other power plants in the basic equipment.
In addition, in order to reduce dust pollution caused by coal transportation by automobiles, the company invested about 120 million yuan to set up a special line for Huaneng Luoyang Thermal Power Railway, which starts from Wangtun Village North of Luolong Science Park and west of Huaneng Luoyang Thermal Power The company's coal storage base, 5,000 tons of coal per day into the plant, to achieve the entire closed transportation of coal.
The company is a microcosm of the ultra-low emission control of coal-fired units in our city. Relevant person in charge of Municipal Environmental Protection Bureau introduced at present, the city is accelerating the transformation of ultra-low emissions, before the end of October this year, a single output of 65 tons of coal-fired boilers to be completed super-low emissions control.
The Coating Machine is suitable for coating of powder, granules, pellets, enteric release, slow and control release coating. Making use of fluid-bed technique and spray technology , low productive cost, and the coating material is used perfectly. It is particularly fit for many field such as industry, foodstuff, chemical industry. The prepared granule is porous and can solve quickly. with high sphericity, good surface luster ,certain intensity and is not easy to break. It can deal with low moisture-absorb and fluidity material to gain complete granule.
