Reproduction of Blue Water and Blue Sky in Re-burning Magnesia Pollution Control

Dust produced during the production of magnesia by heavy burning also causes land consolidation, which seriously affects the air quality and the living environment of the people is worse. This problem left over for many years has brought historical trauma to Haicheng, a resource-based city. At present, the government's governance determination and entrepreneurs'social responsibility make people full of hope for environmental improvement.




In front of the magnesia kiln of Haicheng Magnesium Mine in the archway, the double electric horizontal electrostatic precipitator in the test is working. The head of research and development unit told reporters that the advanced dust removal equipment is being tested, and the operation effect is good at present. In the past, the amount of dust around the kiln was very large, just like a drizzle. After using this equipment, the amount of dust per cubic meter dropped from 7000 mg to 110 mg, which is far below the national emission standards.




In response, Wang Mengyan, director of the refractory plant of Haicheng Magnesium Mine, said that the state-owned enterprises have the responsibility to make efforts for the improvement of the environment. In recent years, enterprises have invested 56 million yuan in environmental control work such as dust removal equipment renovation. Nowadays, dust emissions from light-burning kilns and fused magnesium can meet the national standards. After the successful trial of this new dust removal equipment, it will play an important role in environmental improvement. Use.




During the visit, the state-owned and private enterprises such as Pailou Magnesium Mine, Haicheng Magnesium Mine School Refractories Factory, Donghe Group, Houying Group Development Zone Magnesium Brick Factory and so on also invested a lot of manpower and material resources in dust removal. Some enterprises reused dust and produced considerable economic benefits. Entrepreneurs'awareness of environmental protection has also been greatly improved, which has played a good role in promoting pollution reduction and air quality improvement. Local people and workers are very supportive of this. Workers are happy to tell reporters: "The factory is equipped with environmental protection equipment, the smoke and dust are gone, the work is not choked, the labor intensity is reduced, and the environment is not polluted. This is a good thing for future generations."




According to the relevant personages of Haicheng Environmental Protection Bureau, Haicheng Municipal Committee and Municipal Government attach great importance to the environmental pollution caused by Magnesite Industry in eastern mountainous areas, and make every effort to improve the production environment of Magnesite Industry from rectifying and standardizing the order of mining development, supporting the intensive processing of magnesite resources, promoting industrial clustering and enterprise parks, controlling pollution of magnesite enterprises and restoring mine ecology. Especially in this year's Haicheng government work report, the regulation of dust, smoke and dust "three dust" pollution in eastern mining enterprises is an important part of this year's work, and a special leading group for the regulation work is set up to clarify measures such as limited exploitation of resources and management of enterprise parks. Through these measures, the mining layout of magnesite talc resources in Haicheng is basically reasonable, the safety production situation of mines is obviously improved, the ecological environment of mines is obviously improved, the price of mineral products has been significantly raised, and the development and utilization of magnesia resources has entered a standardized, intensive and large-scale development track.




Reporters also learned that Haicheng has made great efforts to promote the development of magnesium resources intensive processing industry in recent years, and has successively built a number of large projects such as Houying Magnesium High-tech Park with an investment of 1 billion yuan, Houying Group with an investment of 500 million yuan, 50,000 tons of new composite magnesia-calcium-zirconium bricks, energy saving and emission reduction, and circular economy. A total of 200 million yuan has been invested in comprehensive environmental pollution control of magnesium products enterprises. Over the past five years, 680 magnesia kilns have been harnessed in the whole city, including 100 re-burning kilns, 80 electric melting kilns, 300 light burning kilns and 200 electric melting kilns. The harnessing rate has reached 95%, and the air quality in eastern mountainous areas has been significantly improved.
