[0002] Thanks to the continuous innovation of science and technology, people can analyze the sulfur content in samples. People generally place steel samples in a combustion furnace for combustion, obtain and collect special gases through combustion, and then go through a chemical analysis procedure to quantitatively and quickly analyze the sulfur content in the sample. The combustion furnace generally uses a high-voltage, high-frequency oscillation circuit to form an instantaneous large current to ignite the sample, so that the sample quickly burns under oxygen-rich conditions to produce a mixed gas.
[0003] The existing catalytic combustion furnace lacks a purification device and requires an additional long pipe to transmit the exhaust gas to the purification device, which wastes space and resources, and requires manual discharge of the exhaust gas. The high exhaust gas temperature poses a risk of scalding workers. The existing catalytic combustion furnace needs to continuously use fuel for heating when burning metal and lacks the function of heat preservation and smoldering, which is relatively wasteful. Therefore, a catalytic combustion furnace for exhaust gas purification is proposed to address the above problems. Utility Model Content

[0022] Working process: when the catalytic combustion furnace 1 for exhaust gas purification is needed, firstly, the first sealing cover 9, the first heat insulation layer 7 and the first sealing block 8 are turned and unscrewed to open the feed port 6.
