Product Description

Sodium Bicarbonate Ultrafine Grinding System Special Milling Machine Impact Mill
Suitable for municipal waste incineration, hazardous waste incineration, sludge incineration, cement plants, glass factories, steel mill coke ovens, etc., can remove the acidic substances in the exhaust gas, such as SO2, HCl, etc., to help discharge sewage Enterprises achieve standard discharge.

FEATURES AND ADVANTAGES

• Dry desulfurization process can remove more than 95% of SO2 and 99% of HCl in tail gas
• Low failure rate, stable operation, suitable for continuous operation, annual operation time is over 8000 hours.
• Simple and reliable process, low investment, low operating cost and short construction period.
• Auxiliary (sodium bicarbonate) and residue, non-irritating, non-toxic.
• The residue is a dry solid with low emissions.
• The amount of desulfurizing agent injected can be automatically adjusted according to the fluctuation of the concentration of harmful substances in the flue gas.
• The cost of the desulfurizer is high, but the entire line project has low operating costs.
• Grinding and classifying integrated design, to achieve the desired product size by adjusting the classifier wheel speed.
• The particle size distribution is narrow, the product size is D90: adjustable between 10 and 45μm, and the shape is good.
• The high air volume is designed to reduce the grinding temperature. Optional cold air device if there is a high temperature requirement.
• Compact structure, easy to remove and wash mills and fans.
• The grinding mill comes with a power-saving flip device, and the fan has an inspection hole for quick maintenance.
• Grinding is in closed system, little dust, low noise in a clean and environmentally friendly process.
• Intelligent control system, one-button operation, online monitoring of key parameters such as sulfur dioxide concentration, system air volume, feed amount, grinding temperature.
• Optional online cleaning to prevent material sticking and reduce downtime.
• Optional explosion-proof design.   

WORKING PRINCIPLE
In the high-temperature flue gas pipeline, the pulverized sodium bicarbonate (sodium bicarbonate) is used as an adsorbent for flue gas desulfurization, and is directly sprayed into a high-temperature flue gas pipeline to decompose sodium carbonate by high temperature to form sodium carbonate Na2CO3, H2O and CO2. . The newly formed sodium carbonate Na2CO3 has high reactivity at the moment of formation, and can efficiently react with acidic substances in the flue gas to help the desulfurization enterprises achieve the discharge standard.

Use of Sodium Bicarbonate

Sodium bicarbonate (NaHCO3), used as an adsorbent for flue gas desulfurization, is sprayed into high-temperature flue gas directly, sodium bicarbonate decomposes at high temperature to form sodium carbonate Na2CO3, H2O and CO2. The newly produced sodium carbonate Na2CO3 has a high reactivity at the moment of formation, can efficiently react with acidic substances in the flue gas, remove more than 95% of SO2; the removal rate of HCl can reach 99%.

Principle of chemical reaction of sodium bicarbonate

NaHCO₃ + HCl     →   NaCl  + H₂O + CO₂
2NaHCO₃ + SO₂ +  ½ O₂   →   Na₂SO_{4 + H2O + 2 CO2
NaHCO3 + HF    →    NaF  + H2O +  CO2}

Characteristics of Sodium Bicarbonate Flue Gas Treatment

• The process is simple and reliable;
• The auxiliary (sodium bicarbonate) and the residue are non-irritating and non-toxic;
• The residue is dry solid with a small amount;
• Could adjust sodium bicarbonate input with the concentration of harmful substances;
• Auxiliary costs are higher, but processing costs are low.
