Ignition process system of Claus sulfur recovery converter

The utility model discloses an ignition process system of a Claus sulfur recovery converter, which is characterized by comprising a Claus reactor (1) and a 1 # converter (2) connected with the Claus reactor (1) through a pipeline (10), an ignition bypass pipeline (3) is additionally arranged on the pipeline; the ignition bypass pipeline (3) comprises a first gate valve (4) and a second gate valve (5); the ignition bypass pipeline (3) is communicated from the front of the first gate valve (4) to the bottom of a chimney (9) for discharging tail gas; and an 8-shaped blind plate (6) is arranged behind the second gate valve (5). According to the utility model, by adding the ignition bypass process pipeline and using the chimney effect, the hearth pressure of the 1 # converter is reduced, and the safety risk in the ignition process is eliminated. The problem of difficult start-up ignition of the sulfur recovery system is solved, and the situation that the start-up progress of the whole coal-to-methanol process larg
