A catalytic combustion device with low energy consumption

Abstract

The present invention provides a catalytic combustion device with low energy consumption. The device combines a high-temperature combustion furnace with a low-temperature combustion furnace. Because the temperature of the high-temperature combustion furnace needs to be controlled at about 800 degrees Celsius to work, and the temperature is heated by heating the combustion chamber, when the temperature is too low to work in the high-temperature combustion furnace, the temperature is stored in a shared heat storage tank and introduced into the low-temperature combustion furnace. No secondary heating is required. Only about 400 degrees Celsius is needed to be processed in the low-temperature combustion furnace, thereby achieving temperature circulation and reducing energy consumption. Without considering energy consumption, the VOC concentration in the outside world can be detected by a VOC sensing probe. When a high concentration is detected, the VOC is passed into the low-temperature combustion furnace for high-quality purification. When a low concentration is detected, the VOC is passed into the high-temperature combustion furnace, thereby achieving low energy consumption and high VOC purification efficiency. The device has good development prospects.
