At present, about 60% of the domestic converter gas dust removal adopt OG wet process, and the OG wet dust removal outlet particle concentration is 30-60mg/Nm3.

With the improvement of environmental protection standards, the original OG wet dust removal cannot meet the emission standards, needing upgrading and retrofit gradually.

At present, the general solution for achieving ultra-low emissions of converter gas is to adopt dry electrostatic dust removal technology, while the solution of transforming OG wet dust removal into dry dust removal faces problems such as high difficulty, high investment, and long construction period.

In order to promote the application of high-efficiency, reliable and ultra-low emission wet electrostatic precipitators to the converter gas wet dust removal field, our company has conducted in-depth research on converter operating conditions, gas composition, converter gas recovery, discharge operation systems and so on problems, and achieved the safe and reliable application of wet electrostatic precipitator in converter gas OG wet dust removal.

Technical features:

※ The operation of the device is safe, stable and reliable, and can replace similar foreign technology products.

※ Solved the problem of explosion venting of converter gas in wet electrostatic precipitator.

※ The wet electrostatic precipitator is arranged after the gas recovery three-way valve, and the arrangement is flexible, making little changes to the existing system, and will not affect the operation of the existing system;

※ Solve the problem of meeting the emission standard of gas, and the concentration of emission particulate matter can be lower than 5mg/Nm3.

※ The device is automatically matched with the converter operation, which can be fully automatic and unattended operation;

※ The investment is less, the construction period is short, and the interface time when the furnace shutdown only takes 3 to 5 days.
