The invention relates to a glass electric furnace tail gas nitrogen oxide purification device, which comprises a flue gas purification tower, an oxygen absorption tower, a reduction absorption tower, a tail end absorption tower and a flue gas buffer, wherein the air inlet of the flue gas buffer is communicated with an air inlet pipe, the air outlet of the flue gas buffer is communicated with the air inlet of the flue gas purification tower through an air pipe, and the air outlet at the upper end of the side surface of the flue gas purification tower is communicated with the air inlet of the flue gas purification tower through a connecting air pipeThe core ventilator is communicated with an air inlet of the oxygen absorption tower, an air outlet at the top of the oxygen absorption tower is communicated with an air inlet of the reduction absorption tower through a connecting air pipe, an air outlet at the top of the reduction absorption tower is communicated with an air inlet of the tail-end absorption tower through a connecting air pipe, and an air outlet at the top of the tail-end absorption tower is communicated with the exhaust funnel. The purifying efficiency of the novel furnace tail gas nitrogen oxide purifying device is 90-95%, and the emission concentration of the nitrogen oxide in the tail gas of the electric furnace after purification by the novel furnace tail gas nitrogen oxide purifying device can be lower than 400mg/m 3 。 |
