Latest Patents

One of Han's latest patents is a system and method for efficient nitrogen and carbon removal and phosphorus recovery of source-separated fresh urine by biochemical combination. This system includes a functionally zoned membrane aerated biofilm reactor designed for in-situ nitrogen and carbon removal. It also features a source separation toilet, a source-separated urine storage tank, a phosphorus recovery reactor, a calcium salt solution tank, a water production tank, and a control system. The reactor is divided into upper and lower parts, creating a micro-aerobic environment above and an anaerobic environment below, allowing for the effective removal of nitrogen and carbon. This innovative system can achieve over 95% removal of nitrogen and carbon without the need for an additional carbon source, making it suitable for in-situ sewage treatment on trains.

Another significant patent by Han is a yaw calibration method and system for wind turbines. This method involves establishing a cylindrical coordinate graph of wind resource distribution based on historical wind farm operation data. It determines the wind direction interval of main inflow wind conditions and calculates the effective value of active power for each wind speed sub-interval. The method also includes setting an angle between the central axis of a refined interval and a calibration curve to establish a yaw error calibration value lookup table.
