Electric heater mixing apparatus for process air recirculation system
A recently granted patent (Publication Number: US11662142B2) describes a process air recirculation system that includes a dryer, a process air outlet conduit, a reheated air inlet conduit, and an electric heater mixing plenum. The electric heater mixing plenum has an upstream end that connects to the process air outlet conduit and a downstream end that connects to the reheated air inlet conduit. The plenum is divided into two chambers, with separate inlet dampers for each chamber. The first chamber contains a resistance-type electric air heater.
The system can also include a combustion heating system that connects to the electric heater mixing plenum, completing a circuit. Multiple resistance-type electric air heaters can be placed in both chambers of the plenum. Sensors, such as thermocouples, can be installed in the plenum to measure the temperature and pressure of the process air. These sensors transmit the measurements to a controller.
The patent also describes an electric heater mixing plenum as a standalone invention. This plenum has an upstream end that connects to a process air outlet conduit and a downstream end that connects to a reheated air inlet conduit. Similar to the previous system, the plenum is divided into two chambers with separate inlet dampers. The first chamber contains a resistance-type electric air heater. Additionally, sensors are placed in various locations of the plenum to measure temperature, pressure, and humidity of the process air. These measurements are transmitted to a controller.
The electric heater mixing plenum can be used in conjunction with a combustion heating system, a blower, an exhaust blower, and a makeup blower. The combustion heating system is located downstream of the plenum, while the blowers are placed downstream of the combustion heating system. The exhaust blower moves the process air through an exhaust outlet, while the makeup blower introduces makeup air through a makeup air inlet.
Overall, this patent describes a process air recirculation system and an electric heater mixing plenum that can be used in various applications, such as drying processes. The system and plenum allow for efficient heating and recirculation of process air, with the ability to control temperature, pressure, and humidity through the use of sensors and a controller.
