Rubber filter belt

01. Air governance

In the past three centuries, the amount of freshwater resources extracted by humans has increased 35 times, reaching 3500 cubic kilometers in 1970. In the second half of this century, freshwater extraction increased by 4-8% annually, with agricultural irrigation and industrial water accounting for the main part of the growth, especially during the "Green Revolution" in the 1970s when irrigation water doubled. According to international organizations, it is predicted that by 2050, the population living in water scarce countries will increase to between 1.06 billion and 2.43 billion, accounting for approximately 13-20% of the global projected population. The changes in the pattern of China's sewage treatment industry chain have reached a level of specialization. The revolutionary progress of filter belts in sewage treatment technology for factories and mines marks the comprehensive entry of the water treatment industry into the green industry, which can solve problems such as waste liquid pollution, truly achieve clean production, and achieve green mountains and waters as soon as possible. While seeing the current development status, rubber filter belts for fixed chamber belt vacuum filters have huge potential markets in China. Purifying water and air resources is the responsibility and obligation of every citizen, not only beneficial to the present, but also better for future generations. Its successful development has made significant contributions to the washing, purification, energy conservation and emission reduction, reduction of environmental pollution, improvement of production efficiency, and reduction of production costs in China's solid-liquid separation industries such as thermal power generation, papermaking, petroleum, fertilizer, fermentation, and tailings treatment. In recent years, China has created a huge market for flue gas desulfurization alone, generating significant economic and social benefits.

02. Sewage treatment

As is well known, China is a major coal-fired country, and the SO2 emissions from coal have been the highest in the world for many years, leading to serious acid gas pollution in China. According to statistics, 62% of cities in China have seriously exceeded the average concentration of SO2 in the air, posing a threat to the sustained and healthy development of the national economy. Therefore, controlling SO2 emissions in flue gas has attracted high attention from the Chinese government, and a series of measures and standards have been formulated to control SO2 emissions. As stated in the "Reply of the State Council on the Control of SO2 Pollution in Acid Rain Control Zones" (State Letter 1998-5) and "Air Pollution Emissions from Thermal Power Plants" (GB13223-1996). At present and for a long time in the future in our country. The main means of controlling SO2 emissions is flue gas desulfurization. The most economical and technologically mature method for flue gas desulfurization is mainly the limestone gypsum method. In the desulfurization process, the filter belt is specifically used for gypsum dehydration. Filter belts are mainly used for gypsum slurry filtration in wet desulfurization of thermal power plants with a capacity of over 200000 KW, flue gas desulfurization in steel plants, phosphoric acid filtration in phosphating plants, potassium fertilizer filtration in the potassium fertilizer industry, and slurry filtration in large metallurgical mines.
