Energy-saving low-carbon combustion system for ceramic roller kiln

A system, comprising:

• a kiln body having a kiln chamber, a roller conveyor belt, a circulating fan and a heat exchanger, wherein a first retaining wall and a second retaining wall are mounted in the kiln body, and the kiln chamber is divided into three sections:
• a low-temperature section, a medium-temperature section and a high-temperature section by the first retaining wall and the second retaining wall;
• a flue gas exhaust outlet of the low-temperature section is provided with the heat exchanger, an air pipe is connected with an air inlet of the heat exchanger, an air outlet of the heat exchanger is connected with a hot air pipe through a conveying pipe, and the hot air pipe is connected with burners in the medium-temperature section and the high-temperature section through branch pipes;
• the medium-temperature section is provided with a heat introduction outlet which is connected with the circulating fan, and the circulating fan is connected with the kiln chamber in the low-temperature section through the conveying pipe, and flue gas in the medium-temperature section is partially introduced into the low-temperature section;
• and the roller conveyor belt penetrates through the kiln body, wherein the system is configured to allow a ceramic tile to sequentially pass through the low-temperature section, the medium-temperature section and the high-temperature section in the kiln body on the roller conveyor belt to be heated and sintered.
