Information
A factory in Longhua Town, Longmen County, Huizhou City
 
The two 5000t / d cement production lines have a limestone sulfur content of 0.8% -2.0% (average 1.2%), and the SO2 emissions from flue gas have seriously exceeded the standard (1000-3000mg / Nm3).

The SO2 concentration in the flue gas was monitored using a British KANE KM9106 flue gas analyzer. In order to ensure the accuracy of the experimental results, the monitoring instrument was calibrated by the Monitoring Center of the Guangdong Environmental Protection Agency the day before the test.

The SO2 background emission value is about 1600 ~ 1800mg / Nm³; when the powder is used alone 2%, the SO2 concentration can be reduced to within 200mg / Nm3; when the powder dose is 0.3 ~ 0.5% and the water dose is 1.5m³ / h, the SO2 concentration can be stably maintained Within 100mg / Nm³, the emission reduction efficiency is more than 90%.

The amount of "wanyin" composite desulfurization technology powder is 0.07%, 0.1%, 0.5%, 2.0% of the raw material feed amount, combined with the use of water agent 2.0-2.6m³ / h, the SO2 is quickly reduced to less than 100mg / Nm³, which is fully satisfied National and local environmental protection standards.
