Thermal runaway flue gas catalytic purification system for power lithium battery pack

The invention provides a thermal runaway flue gas catalytic purification system for a power lithium battery pack. The system comprises a shell, and a battery pack is mounted in the shell; a smoke sensor is arranged on the top lower surface of the shell; the smoke sensor is connected with a controller through a power signal line; interlayers are arranged on the shell and the top of the shell and communicate with each other, and an air purification material is arranged in the interlayers; and the lower surface of the top of the shell is provided with a top one-way valve communicated with the interlayers, the lower surface of the bottom of the shell is provided with a bottom one-way valve communicated with the interlayers of the shell, the bottom one-way valve is connected with a sucking pump through an exhaust pipe, and the sucking pump is controlled through the controller. According to the invention, smoke generated by battery combustion is treated by adopting an adsorbent and a catalyst, toxic smoke is conver
