AI Technical Summary
Lithium-ion batteries may cause thermal runaway under the influence of factors such as overcharging, overheating or mechanical collision, and produce thermal runaway smoke with safety hazards, including combustible substances such as electrolyte, hydrogen, carbon monoxide, etc., which can easily cause combustion or explosion.
A thermal runaway smoke treatment device is designed, including a buffer device and an adsorption treatment device. The buffer device buffers the thermal runaway smoke through a buffer tank to stabilize the flow rate. The adsorption treatment device adopts a combination of liquid and solid adsorption treatment devices and uses alkaline solution. The electrolyte and combustible gas in the flue gas are adsorbed and treated with activated carbon, and then discharged through the flue gas cooling and ignition device.
It effectively reduces the amount of combustible gas in thermally runaway smoke, improves the safety of lithium-ion batteries, ensures that the treated gas is non-flammable and harmless, and reduces emission hazards.
