Haicheng has a quarter of the world's magnesite reserves, Magnesite Industry is the pillar industry of Haicheng. However, the environmental pollution caused by the production process of light burning magnesia powder has brought historical trauma to the environment of Haicheng, a resource-based city. In recent years, Haicheng has actively promoted pollution control of magnesia industry, reduced smoke and dust emissions, and improved the atmospheric environment.
Recently, the Organizing Committee of Haicheng Environmental Protection Century Committee went to Anshan Aohai Refractories Co., Ltd. located in Daxincun, Bali Town, Haicheng City. The workers on the project site are installing the dust removal equipment. Wang Wenming, general manager of the company, said that the company was established at the end of 2004 as a Sino-Australian joint venture, mainly producing and selling large crystals and fused magnesium products. The original dust removal equipment of the enterprise is a small horse-drawn cart with 2 electric smelting magnesia furnaces in each set. Due to the aging of the equipment, the dust removal efficiency, the organized emission concentration of smoke and dust, and the emission amount are not up to the standard. In the downturn of magnesia industry, considering environmental protection, the company invested more than 30 million yuan to dismantle the original electric melting furnace and dust collector, build 32 4000KVA electric melting magnesia furnaces, and set up new advanced dust removal equipment. Eight of the 16 electric smelting magnesia furnaces and dust removal equipment constructed in the first phase have been completed and put into production, and eight are under construction, and are expected to be completed and start trial production in mid-July. Sixteen magnesium smelting furnaces and dust removal equipment for the second phase are expected to be completed in 2017. After the completion of the project, the comprehensive dust removal efficiency will reach over 98.5%, which fully meets the requirements of the national emission standards.
In Haicheng Sanyan Mining Co., Ltd., the upgrading and transformation project of light-burning reflector kiln has been basically completed. According to Shi Changgui, deputy manager of the company, in order to improve the pollution problem of magnesia production, the company invested 5 million yuan this year, demolished the original Earth-Water gas station, built an environmental-friendly and energy-saving mechanized thermal De-Coking gas station, and built a new gas station to save energy, reduce energy consumption, increase thermal efficiency by 10%-20%, improve product quality by one percentage point, and reduce fuel costs by more than 15%. With high mechanization, safe and reliable operation and large gas production capacity, a gas station can be used for the production of multiple light burning kilns at the same time. More importantly, the environment of enterprises has been greatly improved, the concentration of soot and sulfur dioxide has been greatly reduced, which meets the national first-class emission standards, and has changed the situation of smoking, energy consumption and heavy pollution in the past. Since the introduction of this technology, it has achieved better environmental protection and energy saving effect, reduced production costs, improved labor productivity, and brought greater economic and social benefits to enterprises.
According to the staff of the environmental protection department, in addition to these two projects, three dust removal projects in magnesia industry will be completed in September in Haicheng this year, which can greatly reduce smoke and dust emissions and improve the air quality of the whole city.
