Abstract
The utility model discloses a treatment device for waste gas generated by coal combustion, which comprises a liquid NO2 storage device, a liquid SO2 storage device and an external pipe, wherein the liquid NO2 storage device is communicated with an outlet of waste gas generated by coal combustion through a first connecting pipe; a first refrigerator is arranged in the liquid NO2 storage device; the liquid SO2 storage device is communicated with the liquid NO2 storage device through a second connecting pipe; a second refrigerator is arranged in the liquid SO2 storage device; the external pipe transfers gas to a plant zone; and an inlet end of the external pipe is communicated with the liquid SO2 storage device. By lowering the temperature of the connecting pipe and the storage devices, NO2 and SO2 generated by coal combustion are liquefied, and discharged to the plant zone by using the residual highest-content CO2. The utility model can effectively treatment NO2, SO2 and CO2 generated by coal combustion, has the advantages of simple structure, low cost and wide application range, and is suitable for many devices using coal combustion, such as boilers and the like.
