Abstract

The invention relates to the field of chemical or biological purification of waste gas, in particular to a smoke gas denitration device for a combustion machine. The smoke gas denitration device for the combustion machine comprises a denitration reaction device and an ammonia gas conveying device, wherein the denitration reaction device comprises a reaction casing, an ammonia spraying grid, a heatexchanger and a denitration catalyst module; an ammonia water conveying device comprises an ammonia water storage tank, an ammonia water conveying pipe, an ammonia water conveying pump, an ammonia evaporator and a dilution fan. Compared with the existing smoke outlet denitration device for the combustion machine, the smoke gas denitration device for the combustion machine provided by the invention has the advantages that the smoke gas is subjected to temperature lowering denitration; then, afterheat is recovered; the problems that the combustion smoke gas in the prior art is directly exhausted, and no efficient and reasonable smoke gas denitration device is used for performing denitration treatment on the smoke gas exhausted by the combustion machine are solved; the atmosphere environmentis improved; the ecological stress is relieved.

Description

technical field [0001] The invention relates to the field of chemical or biological purification of waste gas, in particular to a flue gas denitrification device for a combustion engine. Background technique [0002] The high-temperature flue gas from the gas turbine is connected to the boiler through the flue, and the waste heat is recovered and discharged directly into the atmosphere. Since the transition flue distance between the gas turbine and the waste heat recovery boiler in most of the gas turbine power generation projects is very short, it is difficult to directly In the transformation of the middle position, the addition of denitrification in the middle of the waste heat boiler is limited by the space and transformation time, which affects the cost and is extremely difficult. Most of the existing SCR flue gas denitrification technologies are mainly used in coal-fired boilers. At present, gas turbine denitrification is still in the preliminary stage. Due to the grad...
