This is an exhaust gas treatment device designed to neutralize and release ethylene oxide gas (hereinafter referred to as EOG) into the atmosphere. 【Features of the EOCS Series】 ◇ High Decontamination Efficiency - Capable of reducing EOG concentration to below 1 ppm at maximum. ◇ Energy Saving - Achieves energy savings by partially recirculating high-temperature treated exhaust gas. - Eco operation system that appropriately controls a specially designed burner. ◇ Excellent Safety - Ensures safety through various interlocks and multiple safety monitoring systems. ◇ Ease of Use - Simple operation with standard combustion safety equipment and temperature control devices. - Automatic operation possible via signals from the sterilizer side. ◇ Versatile Combinations - Simultaneous treatment of gases including EOG from not only sterilization devices but also aeration chambers and local exhausts can be achieved with a single "EOCS" unit. ◇ High Design Flexibility - Heat sources can be electric or gas combustion types. - Treatment capacity can be designed from a minimum of 0.1 m³/min. * A "catalytic type exhaust gas circulation" specification is also available in the lineup, which aims to reduce costs by not using heat exchangers while partially recirculating exhaust gas for energy savings.

【Example Introduction】 This is a curing furnace for resin-impregnated glass tubes used in storage batteries. ◆ Traditionally, the temperature distribution was not uniform in both the width and length directions, and production adjustments were made by varying the feed speed. ◇ By reviewing the arrangement of electric heaters and introducing hot air utilizing exhaust heat, the temperature distribution has improved, allowing for an increase in production volume. ~ In this case ~ The heat from the deodorized exhaust gas treated by the exhaust gas treatment system is recovered through a heat exchanger and reused in the furnace. This not only helps to equalize the temperature inside the furnace but also contributes to energy savings. The heat source can be electric, gas combustion, or hybrid, making it applicable to various works (heated objects). 【Specifications Example】 ● Application: Curing furnace ● Processed material: Glass tube ● Feed speed: 8–10 m/min ● Temperature: 230–300℃ (furnace atmosphere) ● Heat source: Seize heater ● Heater capacity: Total 80 kW ● Effective dimensions: W2040×L8500×H210 ● Exhaust gas treatment: Direct combustion deodorization device (LPG burner) ● Equipped with an exhaust gas treatment device (manufactured in-house) that deodorizes volatile components, achieving energy savings by introducing its exhaust heat into the furnace.
