Problems solved by technology

The regenerative catalytic oxidation furnace has at least two regenerators to complete the periodic heat storage and release of the regenerator, which requires a large number of regenerators. Therefore, this device has a complex structure and is much larger than the catalytic direct-fired furnace. This also makes its investment cost much higher than that of catalytic direct combustion furnace

Abstract

The invention relates to a regenerative catalytic direct combustion system for treating VOCs waste gas. The system comprises a waste gas inlet pipe, a catalyst direct combustion chamber, a flue gas outlet pipe, an air inlet pipe, an air outlet pipe, a draft fan and an exhaust funnel. An anti-explosion door is installed at the top of the catalyst direct combustion chamber. One end of the catalyst direct combustion chamber is provided with a main burner, the other end of the catalyst direct combustion chamber is provided with an auxiliary burner. The air inlet pipe and the waste gas outlet pipe are inversely installed. A thermal couple and a catalyst layer are respectively installed at two sides in the catalyst direct combustion chamber. At least two layers of regenerative body are installed between catalyst layers. The regenerative catalytic direct combustion system for treating VOCs waste gas is reasonable in structure, good in energy-saving effect, low in investment and operation cost, and high in VOCs treatment efficiency, and therefore the system can be widely used in the field of VOCs waste gas treatment.

Description

technical field [0001] The invention belongs to the field of VOCs waste gas treatment, in particular to a regenerative catalytic direct combustion system for treating VOCs waste gas. Background technique [0002] Volatile organic compounds (VOCs, Volatile Organic Compounds), sulfur oxides, nitrogen oxides and dust are the main pollutants that cause air pollution. The composition of VOCs is complex, and there are many sources of waste gas containing VOCs (such as petroleum refining, organic chemical industry, medicine, food, daily necessities, tire manufacturing and other VOCS production industries, as well as packaging and printing, machinery manufacturing, electronic product manufacturing, transportation equipment manufacturing, wood-based panels and Furniture manufacturing and other manufacturing industries that use VOCS products as raw materials), so there are many ways to deal with VOCs. For the exhaust gas containing VOCs, the treatment effect can reach more than 95% s...
