Description

Technical Field

[0001] The utility model relates to the technical field of soot blowers, in particular to a soot blower for a cylinder wall of a desulfurization reactor. Background Art

[0002] At present, when the boiler is in use, it is necessary to cooperate with the desulfurization reactor to desulfurize the flue gas of the boiler so that the flue gas discharged by the boiler meets the emission standards. After long-term use, the inner wall of the desulfurization reactor needs to be cleaned to ensure the stable operation of the desulfurization reactor.

[0003] At present, a sootblower is generally used to clean the inner wall of a desulfurization reactor. During the use of the sootblower, an air pipe and a nozzle are generally used to blow soot. That is, during use, air is supplied into the air pipe by a blower or other air supply equipment, and then the inner wall of the reactor is sootblown by a nozzle connected to the air pipe to prevent dust accumulation on the inner wall of the reactor. Since the nozzle is fixedly installed inside the reactor, it is easy to cause incomplete sootblowing during sootblowing, and dust condensation may occur. Therefore, it is necessary to design a sootblower for the cylinder wall of a desulfurization reactor. Utility Model Content

[0030] Specifically, when the soot blowing operation is performed on the cylinder wall of the desulfurization reactor, the connecting pipe 4 is connected to an external gas source.
