description The invention discloses a hot nitrogen purging protection device and method for coal gas oxygen measurement after coking electric capture. A laser gas analyzer AT01 for oxygen content measurement of coal gas is arranged on a coal gas pipeline at an outlet of an electric tar precipitator. The purging protection device comprises a high-temperature nitrogen purging pipeline and a room-temperature nitrogen pipeline, a room-temperature nitrogen source is heated by a heater R to become high-temperature nitrogen, one path provides high-temperature nitrogen for working for the electrical tar precipitator, and the other path is connected to the high-temperature nitrogen purging pipeline. The high-temperature nitrogen purging pipeline is connected to purging flanges on the two sides of the laser gasanalyzer AT01, and the room-temperature nitrogen pipeline is connected to an explosion-proof gas input port of the laser gas analyzer AT01. The advantage that a measuring point is close to a high-temperature nitrogen pipelin
