Small laboratory airflow milling, high precision: the most exclusive D50 = 0.3 microns, and the accuracy can be controlled at the maximum particle size of no more than 3 microns. Small noise: The main operating components are imported components such as bearings, air blowers, etc., and air compressors such as needle. Small floor area: It is integrated on a platform for about 1 meter, no more than 2 meters, and installs the mandrel wheel, movable and fixed. Easy to operate, easy to disassemble, easy to clean.Sodium bicarbonate (small soda) can be chemically adsorbed to remove acidic contaminants in flue gas, and some inorganic and organic materials can also be removed by physical adsorption. Therefore, sodium bicarbonate (small soda) is usually used in the adsorbent of flue gas desulfurization and plays an important role in environmental protection. Sodium bicarbonate (small soda) needs to be processed by the ultrafine pulverizer before being put into use, so that it is small particles, increasing its surface area, and the device generally used is a MQL mechanical ultrafine pulverizer. The following is a detailed introduction to how the MQL type ultrafine pulverizer makes sodium bicarbonate (small soda) easily achieve environmental requirements.
Sodium hydrogencarbonate is usually crude particles (D50 value of approximately 150-200 microns). To achieve a higher reaction activity, the adsorbent must have a large specific surface area, ground to a certain fineness (D90: 20UM or the suitable particle size adjusted as needed). For example, to remove SO2 sodium hydrogencarbonate fineness must reach D90 This dry desulfurization technology can be used not only for coal power plants, garbage or alternative fuel incineration plants, but also use in glass, cement, metallurgical and other industries. Industrial furnace. The use of dry flue gas can be economically achieved (eg, China's GB 13223). Sodium hydrogencarbonate (small soda dethinated) dry desulfurization MQL-type ultrafine pulverizer produced in Shandong Erfa can effectively help environmental protection project!
< 20 µm。For HCl removal, D90 < 35 µ m is required. In order to obtain the required fineness of sodium bicarbonate in long-term operation, a complete set of grinding and powder spraying device is usually combined with MQL ultra-fine pulverizer with its own classification system and conveying fan. The fine sodium bicarbonate powder crushed by MQL ultra-fine pulverizer has layered or porous structure, uniform particle size and good dispersion, Then, the solid ultrafine powder is directly sprayed into the furnace or reaction tower through a plurality of nozzles. It can effectively remove more than 95% of SO2 and HCI in tail gas, and the removal rate can even reach 99%.
