Quality and efficiency improvement, innovation-driven, green development-2020 National Glass Industry Technology Seminar and Energy Conservation and Environmental Protection Exchange Conference was successfully held

Jan 06,2021


Shandong Aiyipu environmental protection technology joint stock company was invited to participate in this meeting with the flue gas treatment process of the new dust, sulfur and nitrate integration in the glass industry. The general manager Rong Weilong mainly explained the disadvantages of the existing environmental protection process in the glass industry and the advantages of the new dust, sulfur and nitrate integration process. The advantages, engineering cases, and other aspects were explained. A wonderful keynote speech was given at the meeting, which won the attention and praise of the participating experts and enterprises. After the meeting in the morning, the person in charge of the representative enterprise in the glass industry had a more in-depth conversation with Mr. Rong. Mr. Rong's theory was combined with practice to exchange flue gas treatment plans for different projects and working conditions.

At this seminar and energy conservation and environmental protection exchange meeting, Aiyipu focused on the integrated solution of flue gas dust removal, desulfurization and denitrification. This technology is Aiyipu Environmental Protection's in-depth research on glass kiln dust removal and denitrification technology in recent years. The flue gas treatment technology of the furnace subverts the traditional process route of first denitrification, then dust removal and then desulfurization of glass flue gas. The scheme of dry desulfurization and then entering the dust and nitrate integrated treatment device is adopted. The failure rate of environmental protection equipment is low, and the amount of denitrification catalyst is greatly reduced. The service life can reach more than 5 years without replacement, and the utilization efficiency of waste heat is also greatly improved, which greatly reduces the operation Cost. The use of catalytic materials has a wide temperature range, and the use of metal filtration breaks the limitation of traditional materials not being temperature resistant. The effective use of synergistic catalytic materials allows the catalytic materials to perform perfectly. It can ensure that the dust removal is as low as 5mg/m3 and the denitration efficiency is as high as 90%, while reducing the amount and cost of catalysts by 80%. With the further enhancement of environmental protection policies and the further reduction of the emission indicators of the three major pollutants, it is believed that the products of this project will become a solution with higher comprehensive benefits for flue gas treatment in cement kilns, glass kilns, biomass boilers, waste incineration and other industries.


Aiyipu Environmental Protection was established in 2012, focusing on the treatment of flue gas nitrogen oxides in non-electrical industries. It is a national high-tech enterprise with R & D, production and denitrification system integration of denitrification catalysts. The main business is SCR denitrification catalyst production; flue gas denitrification system design and integration; high-temperature dust removal and denitrification integrated products and equipment, etc. The existing production line has an annual output of 3000m3 honeycomb denitrification catalysts, 1000m3 coated catalysts, 300,000 square meters of high-temperature dust removal metal filter cartridges, and a capacity of 100 sets of flue gas monitoring and denitrification systems. At present, more than 1,000 denitrification projects have been completed in the fields of cement, glass, chemical industry, internal combustion engine, ships, distributed energy, etc. It is a qualified supplier of Sinopec Group and China National Petroleum Corporation system network access, and a member of China Denitrification Industry Alliance.

Driven by scientific and technological innovation, the company's annual R & D investment accounts for more than 6.5%, and has applied for more than 40 patented technologies. The existing independent patented products can cover the denitrification needs under the conditions of low temperature from 150 ° C to high temperature flue gas at 600 ° C, and can provide high-efficiency integral molding catalysts with 50 holes, 60 holes and higher holes. After years of technical accumulation, the company has formed its own unique technical advantages in the field of denitrification catalysts, has rich technical reserves, and has mastered efficient and comprehensive denitrification catalyst production technology. The low temperature catalytic denitrification technology, medium temperature denitrification catalyst technology, high temperature denitrification catalyst technology, carbon monoxide removal technology, high temperature dust removal and denitrification integration technology and other technologies independently developed by the company have been successfully applied to iron and steel metallurgy, cement building materials, electric power, glass, biomass power generation and other industries, making the catalysts provided by the company to customers have many advantages such as good emission effect, low construction cost and operating cost.
