Steel industry
The country's requirements for environmental protection are becoming more and more stringent, and the requirements for dust emission standards in iron and steel plants are getting higher and higher.
It is an inevitable development trend to continue to improve dust removal technology and filtration efficiency. Therefore, the role of filter media in industrial dust collection is becoming more and more important. It is highly valued. According to the nature and characteristics of dust, the reasonable selection of filter material varieties is of great significance to improve the dust removal efficiency, prolong the service life of the filter bag and the efficient and energy-saving operation of the system. Based on years of research on the performance of various fibers, our company manufactures , The exploration of relevant post-processing and filtration principles, according to the production process, dust properties and working conditions of the iron and steel industry, we provide a variety of targeted filter material solutions for users to choose.
| Name | working condition | Filter material selection | Advantage |
| Blast furnace gas dry dust removal | 1. High temperature, high concentration and high pressure of flue gas 2. The composition of flue gas is complex, often carrying hot iron, slag dust particles and other particulate matter and fine fly ash. 3. The working condition of flue gas is unstable, especially with large temperature fluctuations 4. Smoke The amount of gas generated is large, and it is affected by the uneven wind speed and pressure | P84+ superfine glass fiber composite filter | The self-developed 4-micron ultra-fine glass fiber is reasonably matched according to the different fiber structures, so that the cohesion of the product, the peeling strength between the felt layer and the base cloth are improved, and the service life of the filter bag is prolonged. |
| Lime kiln dust removal | The flue gas temperature of the shaft kiln is between 80 and 200 °C, and the working conditions require the filter material to have high temperature resistance, alkali resistance and hydrolysis resistance. | Nomex Composite Needle Felt | The product has a three-dimensional microporous structure and has the characteristics of high temperature resistance, corrosion resistance, wear resistance, folding resistance, hydrolysis resistance, and easy cleaning. |
| The flue gas temperature of the rotary kiln is between 200 and 300 degrees, the humidity is high, and the dust concentration is high. The working conditions require the filter material to have high temperature resistance, hydrophobicity and high dust peeling force. | Slimming and bulking yarn woven film | Due to the fluffy yarn, strong covering ability, higher filtration efficiency and filtration speed, it has good dust capture performance |
