Sodium bicarbonate (baking soda desulfurization) crusher dry desulfurization grinding system

Using sodium bicarbonate (baking soda)
Dry desulfurization not only meets strict environmental requirements, but also effectively reduces investment and operating costs compared to other flue gas purification methods.
Below we will provide a detailed introduction to how the sodium bicarbonate (baking soda) grinding system achieves effective operation and easily meets environmental requirements.

Sodium bicarbonate (baking soda) grinding system

Sodium bicarbonate raw materials are usually coarse particles (with a d50 value of approximately 150-200 microns). To achieve high reaction activity, the adsorbent must have a large specific surface area and be ground to a certain fineness (d90: 20um or an appropriate particle size adjusted as needed). For example, to remove SO2, the fineness of sodium bicarbonate must reach 90%

In order to obtain the required fineness of sodium bicarbonate during long-term operation, a complete set of grinding and powder spraying device is usually composed of a crusher with a built-in grading system and a conveying fan. The crushed sodium bicarbonate fine powder has a layered or porous structure, uniform particle size, and good dispersibility. Then, it is directly sprayed into the furnace or reaction tower as solid ultrafine powder through multiple nozzles. It can effectively remove over 95% of SO2 and HCI in exhaust gas, and the removal rate can even reach 99%.

This dry desulfurization technology can not only be used in coal-fired power plants, waste or alternative fuel incineration plants, but also widely used in industrial furnaces in industries such as glass, cement, metallurgy, etc. The use of dry flue gas purification can economically meet the flue gas emission standards (such as China's GB 13223).
