Description
Technical Field
The utility model relates to a gas turbine electricity generation exhaust-gas treatment technical field, especially a gas turbine generator waste gas high temperature burns processing apparatus.
Background
With the increasing awareness of environmental protection and the strictness of environmental protection requirements, the treatment of exhaust gas generated by the power generation of a combustion engine has become an important issue. Incineration is an effective waste gas treatment method, pollutants such as VOCs in gas can be decomposed at high temperature and oxidized into substances such as carbon dioxide and water, and the method has the characteristics of thorough pollutant treatment, wide application range and the like. However, the use of thermal incineration techniques to raise the gas temperature to pollutant decomposition/oxidation temperatures (typically >800 ℃) is a highly energy intensive process. The lower limit of the decomposition/oxidation temperature of pollutants can be reduced by adopting methods such as catalytic oxidation and the like, but the temperature of the gas still needs to be raised to be more than 400 ℃, and the gas is heated to realize temperature rise, so that a large amount of energy consumption is wasted. By adopting a heat accumulating type process, the heat accumulating chamber sequentially undergoes heat accumulation, heat release, cleaning and other procedures, partial heat energy can be recovered, but clean gas is required to be cleaned after the heat accumulation chamber releases heat (so as to ensure that the VOC removal rate is more than 95 percent) before the heat accumulation chamber enters the heat accumulation procedure. The problems of high failure rate, unstable standard control of tail gas, low treatment efficiency, large equipment volume and the like exist in the actual operation of the system due to the complex operation procedures and the cross of air flow.
For oxidation/combustion reactions that require a certain temperature rise, preheating or direct heating inevitably requires a large amount of energy to be consumed, resulting in energy loss. Meanwhile, for the exothermic reaction caused by temperature rise, the heat released by the reaction cannot be effectively recovered, so that the energy utilization rate of the whole system is low. In addition, the discharge of high-temperature gas cannot meet the environmental protection requirement of green and low carbon.
