Black smoke removal treatment of diesel generator sets for a construction company in Shanghai

YOYO Solution

We designed a self-reverse-blowing, high-temperature-resistant black smoke filter (metal DPF). This metal DPF utilizes imported black smoke filter material, offering high-temperature resistance, low backpressure, a long lifespan, reasonable cost, and long-term maintenance-free operation (maintenance every 6-12 months). Utilizing an advanced rapid regeneration principle, the filter element rapidly regenerates (in less than 1 second per cycle), automatically collecting black smoke and instantly restoring the filter element to a low-resistance state.

Our company is currently the first to implement this solution, which has been widely adopted in engine after-treatment systems and has received positive feedback from users. It solves the problem of DPF clogging and difficulty in back-flushing, which can lead to engine damage. It also addresses the rust and short-term saturation and clogging of conventional metal filters, as well as the potential fire hazard.

After-processing effect

After treatment, the diesel engine exhaust turns into white smoke (water vapor) without black smoke.
