The desulfurization gypsum ball press is the most commonly used one in the ball press. The gypsum wet process is the most widely used and most mature flue gas desulfurization technology of the thermal power plant. The method uses limestone as the desulfurizer and passes through the absorption tower. Spraying the absorbent slurry, mixing with the flue gas, and washing the flue gas, so that the sulfur dioxide in the flue gas reacts with the calcium carbonate in the slurry and the strongly oxidized air that is blown in, and the sulfur dioxide can produce by-product desulfurization gypsum per ton of sulfur dioxide. 2.7 tons. For example, a coal-fired power plant with a capacity of 300,000 kilowatts will emit 30,000 to 60,000 tons of desulfurized gypsum annually if the coal contains 1 to 2% sulfur.

In recent years, the state has strengthened the control of sulfur dioxide emissions from power plants. The flue gas desulfurization industry of coal-fired power plants has developed rapidly. Therefore, the amount of desulfurization gypsum as a by-product is very large, and the desulfurization gypsum has grown rapidly, and its utilization has become an urgent problem to be solved. If the desulfurization gypsum is not treated and utilized in time, it not only occupies a large amount of land, but also poses a serious threat to the natural environment. As industrial waste, long-term stacking will cause secondary pollution. How to timely and thoroughly solve the existing and increasing "desulfurization gypsum mountain" in China is a major problem facing government departments and enterprises.
How to effectively use these wastes to turn waste into treasures is a topic that has always been in-depth research. Through scientific research, the use of dry powder ball press technology, the desulfurization gypsum is pressed into balls and then applied in industrial production. The promotion and use of this type of coal ball press technology not only can treat the desulfurization gypsum of the power plant and the phosphogypsum of the phosphate fertilizer plant every year, but directly saves a large amount of land occupied by industrial gypsum storage and prevents potential pollution to the environment. Moreover, replacing industrial gypsum with industrial gypsum not only saves gypsum mineral resources, reduces ecological damage and environmental pollution during mining and transportation, but also provides products that meet market demand for society, and realizes social, economic and environmental benefits. The three wins.
