Publishdate:2019-10-15 Views:17

As the ultra-low emission transformation of the thermal power industry approaches its end, the focus of air pollution prevention and control work is gradually shifting to the non electric domain, which contributes nearly two-thirds of the total pollutants and has become the main battlefield for air pollution control. There are a large number of industrial boilers in the non electric field, as well as a huge amount of steel, cement, flat glass, electrolytic aluminum, ceramics, refractory materials, etc., and there is a huge market space for atmospheric governance.

At the beginning of its establishment, Fangxin Lihua was located in the non electric low-temperature denitration flue gas treatment market. It made early layout, steadily grasped and developed, and increased research and development efforts year by year. Based on the characteristics of flue gas in different industries, it made formula improvements. After several years of unremitting efforts, it has achieved significant results in the non electric low-temperature denitration flue gas treatment market. After nearly 4 years of continuous and stable operation of low-temperature denitrification (180-200 ℃) of coke oven flue gas in China and Baosteel Zhanjiang Iron and Steel coke oven flue gas, in 2019, Fang Xinlihua obtained a series of orders in non electric fields such as sintering, rotary kilns, waste incineration, alumina, and gas power generation, continuously expanding the scope of low-temperature denitrification treatment in the non electric industry.

Sintering flue gas denitrification industry: Fangxin Lihua has achieved 18 sets of denitrification performance in the sintering industry, of which 11 sets have been put into operation. Among them, the low-temperature denitrification project of Tangshan Ruifeng Steel has been in operation in recent years, and the export nitrogen oxide is maintained at 20mg/Nm ³, It reflects the heteroactivity of low-temperature denitrification. Recently, Fangxin Lihua won the bid for low-temperature denitration catalysts for the flue gas of sintering machines 6 # 7 #, 8 # 9 #, 10 # 11 #, and 12 # 13 # at Rizhao Iron and Steel Co., Ltd. This project follows the concept of wide temperature selection design and low-temperature operation, focusing on solving environmental problems and meeting ultra-low emissions of nitrogen oxides, to achieve low energy consumption operation of environmental protection equipment. The low-temperature denitration catalyst for the 4 # 660 ㎡ sintering machine at Shanxi Taiyuan Iron and Steel Stainless Steel Co., Ltd., which won the bid by Fang Xinlihua, has achieved a breakthrough in adding low-temperature SCR denitration after the activated carbon (coke) desulfurization and denitration process in the sintering industry. After several rounds of scheme demonstration and on-site investigation, the project has finally decided to adopt a 180 ℃ low-temperature denitrification process. For this project, adding a hot air stove at the outlet of activated carbon increases the flue gas temperature. Every increase of 1 ℃ in the operating temperature of denitrification faces huge energy consumption. Balancing the contradiction of "meeting the emission standards of nitrogen oxides at the outlet while lowering the operating temperature", this project fully demonstrates the huge energy-saving potential of low-temperature denitrification in the non electric domain. After the smooth operation of this project, it provides new ideas and choices for steel enterprises that have already equipped their existing sintering machines with activated carbon desulfurization and denitrification devices to achieve ultra-low emissions of sintering machine head flue gas.

Rotary kiln industry: Following the smooth operation of the low-temperature SCR denitrification project for the flue gas of Hubei Zhenhua Chemical Co., Ltd.'s 1 # and 2 # rotary kilns, Fangxin Lihua has successively won the bid for Shanxi Jianlong Steel Co., Ltd. 2 × 800t/d, Dongfang Hope Sanmenxia Aluminum Industry Co., Ltd. 2 × 750t/d, Shandong Xinfa Group Liaocheng Yanju New Materials Co., Ltd. 1 × 800t/d, Dongfang Hope Jinzhong Aluminum Industry Co., Ltd. 2 × Several domestic lime kiln flue gas low-temperature denitrification catalysts, including 1000t/d. The operating temperature for flue gas denitrification in Zhenhua Chemical rotary kiln is 180 ℃, and the imported nitrogen oxide is 400mg/m ³, Export maintained at 50mg/m ³ Within. As a prominent area of non electric flue gas treatment, the lime rotary kiln can achieve seamless integration with the addition of low-temperature SCR denitrification after the existing bag filter at the kiln tail on most existing rotary kilns. At the same time, it can achieve environmental and economic benefits of standard emissions and no heating and heating.

Garbage incineration industry: Due to the low temperature and complex composition of flue gas, the garbage incineration industry is a difficult point in flue gas treatment, especially the key product low-temperature SCR denitrification catalyst, which has long been monopolized by imported catalysts. Taking a 750t/d production line as an example, conventional waste incineration SCR denitrification uses 256 ℃ saturated steam to heat the flue gas after bag dust removal. When the denitrification operating temperature (conventional design 180 ℃ and 230 ℃) increases by 10 ℃, an additional 1.5t of steam is consumed per hour, resulting in a cumulative annual reduction of 2 million kWh of electricity generation, highlighting the strong demand for low-temperature denitrification catalysts in the industry. After years of deep cultivation in non electric low-temperature denitrification, Fangxin Lihua has successfully broken the monopoly of imported products with the catalyst's unique low-temperature denitrification activity and high water and sulfur resistance performance, and achieved performance in nearly ten garbage incineration lines (including under construction) for low-temperature denitrification, accelerating the localization process of low-temperature catalysts in the industry. Ningbo Mingzhou Environment Co., Ltd. 2 × Taking 750t/d waste incineration low-temperature denitrification as an example, this project has been in operation for two years since September 2017. Under high moisture content (23% high) and low temperature (175 ℃) conditions, the export nitrogen oxide has remained stable at 75mg/m ³ Within.

Aluminum oxide, gas power generation, and gas boiler industries: Fangxin Lihua has also received multiple orders for low-temperature denitrification catalysts in industries such as aluminum oxide, gas power generation, and gas boilers. The low-temperature denitrification system of two alumina sintering furnaces of a company in Qingdao, Shandong Province uses Fangxin Lihua catalyst, which has been in operation since February 2019 and has imported nitrogen oxides of 1500-2000mg/m since then ³, Export nitrogen oxide stabilized at 100mg/m ³ Within, it has gained high recognition from the owners. At the same time, we also obtained a supply contract for 2 * 50M low-temperature denitration catalysts for gas power generation from a steel enterprise in Tangshan, and signed multiple supply contracts for denitration catalysts for gas boilers with multiple companies.

2019 was an extraordinary year for Fangxin Lihua, with a good situation of both production and sales. A hundred feet ahead, making progress. Fangxin Lihua is still increasing its research and development investment, and is moving towards the path of ultra-low temperature catalyst research and development. In the future, low-temperature and ultra-low temperature SCR denitrification will inevitably become the choice of non electric low-temperature flue gas and ultra-low temperature flue gas denitrification processes. Fangxin Lihua will continue to provide solutions for non electric low-temperature denitrification.
