AI Technical Summary

Technical Problem

When traditional exhaust gas combustion devices treat volatile organic compounds (VOCs) exhaust gases, the high-temperature environment leads to high energy consumption, and the high-temperature thermal energy in the inner layer is not fully utilized, limiting combustion efficiency and energy consumption optimization.

Method used

The exhaust gas combustion device based on catalyst enhancement is adopted. By introducing a catalyst mesh structure during the combustion process and combining the mesh structure design, the combustion and oxidation and decomposition process of VOCs is optimized, and direct combustion and catalytic combustion are combined with high temperature direct combustion and catalytic combustion to improve combustion completeness and multi-condition adaptability.

Benefits of technology

It significantly improves the efficiency of waste gas treatment, reduces energy consumption, achieves higher combustion completeness and multi-condition adaptability, and provides a more environmentally friendly and efficient solution for industrial waste gas treatment.

Abstract

The invention provides a catalyst-based enhanced waste gas combustion device, which comprises a combustor and a flame guide wall, the combustor is provided with a gas inlet end and a flame jet end, the flame guide wall is arranged on one side of the flame jet end of the combustor, and the flame guide wall is arranged along the circumferential direction of the combustor. A waste gas introduction hole is formed in the end, close to the combustor, of the flame guide wall, and the catalyst metal net is fixedly installed in the end, away from the combustor, of the flame guide wall and located in an outer flame area of the combustor. By adopting the scheme, the catalyst net structure is introduced in the combustion process, and the combustion and oxygenolysis process of VOCs is optimized in combination with the net structure design, so that the waste gas treatment efficiency is remarkably improved, and the energy consumption is effectively reduced. Different from the traditional technology, the device combines high-temperature direct combustion and catalytic combustion for use.
