住友金属鉱山エンジニアリング List of Products and Services

We provide a wet electrostatic precipitator that has a high dust and mist removal rate at high voltage, and can easily remove ultrafine particles such as fumes. Due to its rectangular cylindrical shape, it is sturdy and maintains its initial performance for a long time without significant deformation even after years of use. Additionally, because of the wide electrode gap, there is minimal voltage drop even when dust accumulates on the collection electrodes, ensuring that performance does not decline. [Features] ■ Wide electrode gap ■ Constant voltage control method adopted ■ Continuous cleaning method during charging ■ Equipped with a glow discharge elimination circuit (fire prevention) ■ Voltage control method that follows the concentration of inlet exhaust gas available as an option (energy-saving), etc. *For more details, please download the PDF or feel free to contact us.

High-voltage power supplies for electric dust collectors cannot be installed in areas where flammable gases are present due to the risk of explosion. It is necessary to install the high-voltage power supply far away from the presence of flammable gases and lay a Cottrell cable (paper insulated cable) to supply power to the electric dust collector. However, Cottrell cables have been discontinued for several years, and alternatives are being sought. Our product allows for the high-voltage power supply to be placed in a special pressure-resistant box, enabling installation near electric dust collectors in the presence of flammable gases, thus eliminating the need for laying Cottrell cables.

We provide a wet electrostatic precipitator that has a high dust and mist removal rate at high voltage, and can easily remove ultrafine particles such as fumes. Due to its cylindrical shape, it is sturdy and maintains its shape over many years of use, allowing it to sustain its initial performance for a long time. Additionally, because of the wide electrode spacing, even when dust adheres and accumulates on the collection electrodes, there is little voltage drop, and performance does not decline. 【Features】 ■ Wide spacing between collection electrodes ■ Constant voltage control method adopted ■ Continuous cleaning method during charging ■ Equipped with a glow discharge extinguishing circuit (fire prevention) ■ Voltage control method that follows the concentration of inlet exhaust gas available as an option (energy-saving) and more *For more details, please download the PDF or feel free to contact us.

IGBT (Insulated Gate Bipolar Transistor) has recently garnered attention as a power semiconductor device for power control, serving as an alternative to traditional thyristors. IGBTs combine high-speed switching performance with excellent power control capabilities, making them widely used in various fields, from household appliances to industrial equipment and renewable energy systems. Our company was the first in Japan to adopt IGBT-based high-voltage power supplies in electric dust collectors. This has achieved significant energy savings compared to conventional methods, reducing power consumption during operation and contributing to lower CO₂ emissions. Our IGBT-based high-voltage power supplies balance energy efficiency and environmental considerations with high-efficiency operation, meeting the diverse needs of our customers. Please feel free to consult us regarding new installations or updates to high-voltage power supplies.

Our electric dust collector adopts constant voltage control to achieve high dust collection efficiency. In conventional power-saving control, sufficient energy-saving effects could not be obtained during operation with low gas load. However, we have successfully developed an improved power-saving control that captures the characteristics of the electric dust collector, significantly enhancing energy-saving effects compared to conventional methods. The improved power-saving control can also be implemented in newly installed or existing electric dust collectors using constant voltage control, so customers considering energy-saving solutions for new or existing electric dust collectors are encouraged to contact us.
