In the mighty trend of the times, the cement industry is ushering in an unprecedented green revolution. With the release of "Opinions on Promoting the Implementation of Ultra-low Emission in Cement Industry" on January 15, 2024, the transformation of ultra-low emission in cement industry has been greatly accelerated. Further realizing dust emission reduction and completing the transformation of ultra-low emission have become an important part of the transformation and upgrading of cement industry.
At present, the profit margin of the cement industry is constantly being compressed, and the urgent goal of ultra-low emissions is like the sword of Damocles hanging over the head. Faced with this dual challenge, cement enterprises are seeking to achieve the best emission reduction effect at the lowest cost, in order to find a balance between cost control and environmental protection standards. "Now cement enterprises are considering the most economical investment to obtain the greatest environmental benefits." Wu Kai, general manager of Zhejiang Haokai Filter Co., Ltd. (Hereinafter referred to as "Haokai Filter"), said. Wu Kai
, general manager
of Haokai Filter Industry, generally speaking, dust removal equipment is mainly divided into two categories: electric dust removal and bag dust removal. With the improvement of environmental protection standards, electrostatic precipitator has been difficult to meet the dust removal needs of cement plants, and bag dust removal has gradually become the mainstream choice. However, choosing the right filter bag has become a major challenge for enterprises. There are many kinds of bag filter materials in China, including pure P84 ® filter bag, P84 ® composite filter bag, glass fiber membrane filter bag, domestic PI filter bag, etc. These materials have different performances in filtration effect, service life and pressure difference due to their different performances.
In this innovation of environmental protection technology, glass fiber coated filter bags have risen rapidly with their high efficiency, high temperature resistance, corrosion resistance and other characteristics, and become the darling of the market. Compared with the traditional needled felt filter material, the glass fiber membrane filter bag has a smaller increase in resistance after the operation time is extended, and maintains a higher working efficiency, thus reducing the power consumption. The pressure difference at the kiln inlet of the traditional filter bag may be increased to 200% in the fourth year, which greatly increases the operation cost. Because of the characteristics of surface filtration, the glass fiber coated filter bag has the advantages of easy dust removal, low power consumption, long service life, and saving the cost of air source.
According to Wu Kai, glass fiber coated filter bags also show advantages in actual operation, such as reducing dust removal cycle and electricity consumption, and saving maintenance costs. These characteristics make more and more cement enterprises tend to choose glass fiber coated filter bags in bag dust removal. With this technology, Haokai Filter Industry has established cooperative relations with many large cement groups in China, such as Red Lion, Zhonglian, Huaxin, Conch and Chongqing Oriental Hope . In practical application, these cement enterprises have reached the ultra-low emission level of 2-3mg/m ³ or even "zero" emission level. At a time when the
cement industry is facing many challenges, equipment manufacturers are also facing challenges. "Whether cement enterprises or equipment manufacturers, only enterprises with core competitiveness can survive in this cold winter." Wu Kai said frankly that since its inception, Haokai Filter Industry has regarded product quality as the lifeline of the enterprise, and high efficiency, high cost performance and strong adaptability to working conditions constitute the core competitiveness of Haokai products.
For example, in the process of ultra-low emission transformation of nitrogen oxides in cement industry, because the dust problem is difficult to solve thoroughly, it is easy to cause catalyst blockage, poisoning and wear. The traditional filter material will produce some unavoidable problems in denitration, such as the use temperature usually can not exceed 260 ℃, the phenomenon of "burning bag" or "breaking bag" is easy to occur, the operation resistance is high, and there is secondary pollution in waste recycling.
In order to solve this difficulty, Haokai Filter Industry has also laid out the metal filter bag business while deeply cultivating the glass fiber coated filter bag. The metal filter bag produced by Haokai Filter Industry has entered many cement enterprises with the characteristics of high temperature resistance, corrosion resistance, long life and high reliability, and has been highly recognized.
Haokai Filter Industry goes deep into the market, visits customers closely, understands the actual use, tailors scientific solutions to customers, and provides solid technical support and high-quality after-sales service. The company insists on leading the market by research and development, guiding production by sales, and taking service as the basis. Its products always serve the forefront of various industries and have won a good reputation from customers.
Facing the future, Haokai Filter Industry will continue to uphold the spirit of innovation and constantly improve the technical content and market competitiveness of its products. The company will continue to pay attention to industry trends, keep up with changes in environmental protection policies, and provide customers with more high-quality, efficient and environmentally friendly dust removal solutions. Through continuous technological innovation and high-quality services, Haokai Filter Industry will help the cement industry to achieve green transformation, promote high-quality development of the industry, and jointly meet a better future.
