Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, and more specifically, to an industrial waste gas catalytic combustion device. Background Technique

[0002] Waste gas catalytic combustion is an efficient waste gas treatment technology, mainly used to remove volatile organic compounds, toxic and harmful gases and other pollutants in industrial waste gas. Compared with traditional thermal oxidation technology, catalytic combustion technology has lower operating temperature, higher treatment efficiency and lower energy consumption, so it is more and more valued in industrial applications.

[0003] There is a currently announced Chinese Utility Model Patent No. CN209054571U, named an industrial waste gas catalytic combustion device, which includes a combustion chamber with an air inlet and an air outlet, and a heating pipe, a heat storage element and a catalytic element sequentially arranged in the combustion chamber; the heating pipe is close to the air inlet, and the catalytic element is close to the air outlet; a high-frequency coil is arranged on the heating pipe, and the high-frequency coil is connected to a high-frequency power supply. The heating pipe is electromagnetically heated by the high-frequency coil. The industrial waste gas is heated to a relatively high temperature by the heating pipe before the catalytic reaction, and then the catalytic reaction is carried out. The whole process takes a short time and the reaction is sufficient. The high-temperature industrial waste gas exchanges part of the heat with the heat storage element before the catalytic reaction, and the heat storage element stores part of the heat of the high-temperature waste gas and applies it to the work that requires heat, and will not have a great impact on the temperature of the industrial waste gas.

[0004] However, for the above-mentioned waste gas catalytic combustion device, the heating pipe is electromagnetically heated by the high-frequency coil. This heating method requires winding a coil on the outer wall of the heating pipe, which has a high cost. At the same time, the power consumption increases during use, which leads to an increase in the cost of heating the air and is not conducive to continuously heating and treating the waste gas.
