Abstract

The embodiment of the invention discloses a coke oven combustion waste gas denitration system and method. The system comprises a reducing agent storage device and a reducing agent jetting device located inside a coke oven heat storage chamber and connected with the reducing agent storage device outside the coke oven heat storage chamber through a connecting pipeline, and a first stop valve is arranged on the connecting pipeline. Compared with the prior art, because different denitration technologies are adopted, a denitration catalytic device is not needed; according to the technical scheme, the construction investment is small, the operation cost is low and a small area of land is occupied.

Description

Technical field [0001] The invention relates to the field of purification of coke oven combustion exhaust gas, in particular to a coke oven combustion exhaust gas denitration system and method. Background technique [0002] Coking enterprises will produce a large amount of coke oven combustion exhaust gas during the production process. The coke oven combustion exhaust gas mentioned here refers to the gas produced by the mixed combustion of coal gas and air in the coke oven vertical flue. The generated coke oven combustion exhaust gas contains a large amount of nitrogen oxides (NO x ). At present, the coke oven combustion exhaust gas of each coking enterprise needs to be discharged into the atmosphere through the riser, the regenerator, the small flue, the exhaust gas exchange switch, the sub-flue, the main flue, and the chimney. The regenerator is located in the coke oven. The central part of the main body is a unit for recovering the waste heat of the flue gas, and the direct d...
