Technical Field

Background
Mussels are important economic mussels in China, and researches show that the mussel shells have strong adsorption capacity after being calcined at high temperature. However, mussel shells are easily oxidized by oxygen in the air during firing, and nitrogen is often used as a protective gas to be introduced into the mussel shell calcining furnace for protection treatment because nitrogen is stable in chemical properties and is not easy to react with a protective substance. When the nitrogen protection is performed in mussel firing, nitrogen is often filled into the calcining furnace to replace the air inside, so that the oxygen concentration is maintained within a safe range. However, in practical application, it is often difficult to quantitatively control whether the oxygen concentration in the furnace tube reaches a safe range, and thus the reliability of nitrogen protection is poor. If the oxygen concentration and the pressure value in the furnace pipe can be monitored on line, and synchronous quantitative control is realized, the oxygen content can be controlled within a safe range, and the reliability of nitrogen protection can be effectively improved.
