[Case Study] Oil Smoke Control in Quenching and Tempering Furnaces

An example where the working environment has improved, resulting in workers inhaling less oil smoke.

The blade manufacturing company M has about 10 quenching and tempering furnaces, which caused the factory to be in a state where the other side could not be seen due to the oil smoke. Previously, a fan was used to create airflow from behind the workers to prevent them from inhaling the oil smoke. However, when the indoor space became filled with oil smoke, the fan only ended up blowing more oil smoke into the area, rendering it ineffective. Therefore, we implemented local exhaust for the oil smoke from the quenching and tempering furnaces. An electric dust collector was installed at the discharge port of the automatic quenching furnace. Additionally, hoods were installed near the oil tank and sawdust tank used for quenching and tempering. Ultimately, electric dust collectors were introduced for the seven furnaces that produced a significant amount of oil smoke. As a result, the working environment improved, and the workers inhaled less oil smoke. *For more details, please refer to the PDF document or feel free to contact us.*
