China Drying Network News A new tubular filter developed by Dalian Fahrenheit Fluid Equipment Co., Ltd. passed a continuous operation for one year on the 50,000 tons/year rutile titanium dioxide production line of Sansheng Group Jiangxi Tianguang Chemical Co., Ltd. The "test". The operating data shows that the filtration accuracy of the new tube filter is less than 10 ppm for the residue, which is more than 50% higher than the traditional filtration equipment. The reporter also learned that the new tube filter has a longer service life than similar foreign products, but its price is only half that of imported products. Chief Engineer of Tianguang Chemical Co., Ltd. said that the tubular filter will be the first choice for the filtration of titanium liquids in terms of filtration quality, labor intensity, clean production, water consumption and yield. Filtration and separation processes are one of the main processes for the production of titanium dioxide by the sulfuric acid process. According to Li Yidong, a technical expert in titanium dioxide industry in the country, after some innovations in recent years, some new types of equipment have been used in the production of sulfuric acid process titanium dioxide, which has promoted the development of titanium dioxide industry. However, the titanium liquid filtration process has always been the long-term “universal world†of plate and frame filter presses. At present, nearly 70 titanium dioxide production enterprises in China, each enterprise only need titanium dioxide filtration process generally requires more than two board filter equipment, the country needs at least 140 such filter equipment. Can we have better equipment to replace traditional filtration equipment to improve the operation and on-site environment, improve the filtering effect, and achieve energy conservation and emission reduction? Titanium dioxide companies in the country began boldly trying to use new equipment. Tubular filters thus entered the vision of Timing Chemical. According to Shen Huiliang, deputy general manager of Dalian Fahrenheit, the tubular filter is a kind of precision filtration equipment, which occupies a small area, has a large processing capacity, a high degree of automation, a high degree of filtration accuracy, and is influenced by human factors. Used in petroleum, petrochemical, chemical, pharmaceutical, metallurgical and other industries. In order to ensure the successful use of tubular filters in titanium dioxide enterprises, in 2006, Tianguang Chemical and Dalian Fahrenheit began experimenting with the use of tubular filters for the production of titanium dioxide. After several years of industrial experimental research, Tianguang added light in 2010. Chemicals adopted a tube filter in the hot titanium fluid filtration process of the 50,000-ton/year rutile titanium dioxide production line. The production line was officially put into operation last year. The production operation actually shows that the filtration accuracy of the tube filter can reach the residue content of 10 ppm or less, while the filtration accuracy of the frame filter press is generally 20 to 40 ppm. The same filter area of ​​150 square meters, tubular filter can meet the production needs of 50,000 tons / year titanium dioxide, while the frame filter press can only meet half of the production needs. In addition, the tube filter can also use a variety of control methods to reduce the amount of operation. SZL series biomass-fired steam boiler is package or shop-assembled water tube boiler with double steam drum and chain grate stoker structure. 4-6 tph boiler is package boiler and 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. The former part of boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace; there are dense convection tube bundle between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.
