At present, there are problems in the domestic environmental protection filter material industry, such as incomplete standards, high product homogeneity, and low threshold. The country has standards for filter materials, but due to the rapid development of the domestic filter material market and the increasing variety of filter materials, the national standards have not kept up with the development speed of domestic filter materials, and there are limitations in the implementation of standards.
Environmentally friendly filtering materials are widely used worldwide to eliminate atmospheric dust and reduce PM2.5. There are mainly 10 types of materials used to reduce air pollution emissions, and the mainstream filter materials on the market now include PPS, P84, polyester, aramid, glass fiber, polypropylene fiber, etc; The environmental protection filter material produced by China Energy Conservation Gyrfalcon New Material Group Co., Ltd. (hereinafter referred to as "Gyrfalcon") has passed the experimental test, and the filter precision can reach 99.9995%, which can make the dust emission of the enterprise less than 20mg/m3, about five times that of the previous enterprise's electric dedusting.
Taking the commonly used method of converting electric dust removal to bag dust removal as an example, it is mainly divided into the cost of replacing filter materials and the cost of transforming filter equipment. For example, if a group of 300000 thermal power generation units undergo the "electric bag to bag" process, it may increase the cost by more than 20 million yuan. However, there are currently relevant support policies in the field of enterprise dust removal that can help enterprises reduce transformation costs.
The ultimate goal of retrofitting bag type dust removal in enterprises is to reduce dust emissions. From a social perspective, the benefits obtained from using bag type dust removal are immeasurable. At present, the total industrial discharge of electric dust removal is about 50mg~100mg, which is far higher than the national standard of 20mg~30mg. However, using bag dust removal can reach the maximum emission standard of 10mg, far exceeding the national emission standard.
Environmental friendly filtration materials have two characteristics: filtration and separation. In terms of filtration, they can not only be used in the industrial dust removal field, but also in the field of people's livelihood, such as indoor air conditioning, automotive air conditioning, and other indoor purification fields. At the same time, due to its production process being the same as geotechnical materials, it can also be used for geotechnical materials. In terms of separation, filter materials can also separate heavy metals, precious metals, dust, etc. for utilization.
At present, there are problems in the domestic environmental protection filter material industry, such as incomplete standards, high product homogeneity, and low threshold. The country has standards for filter materials, but due to the rapid development of the domestic filter material market and the increasing variety of filter materials, the national standards have not kept up with the development speed of domestic filter materials, and there are limitations in the implementation of standards. At the same time, due to the low national filter material standards and the low industry access threshold, the product quality is uneven, and the product homogenization is widespread, forming Cut throat competition in the industry market. Moreover, the majority of domestic gas filtration material manufacturing enterprises are private and private enterprises, and their investment in product technology research and development is generally not high, resulting in a generally low level of technology in the industry.
At present, there are mature technologies for recycling and reusing filter materials in China, and there are also 2~3 professional filter material recycling companies in the industry. At the same time, Gyrfalcon has also started the recycling and reusing project of filter materials. It is expected that Gyrfalcon will recycle waste filter materials into engineering plastics, building insulation materials, etc. in the future, which will help solve the environmental problems caused by waste filter materials.
