The invention provides a floating valve
tower cleaning
system and method, and the floating valve
tower cleaning
system comprises a floating valve
tower, a first pipeline, a regulating valve group, a
gas phase outlet valve, a
safety valve group, a silencing valve group, a steam reboiling mechanism, a cooling mechanism, a second pipeline and a
nitrogen mechanism, the first pipeline is connected with the top of the floating valve tower through a pipeline by virtue of the adjusting valve group, the
gas phase outlet valve is connected with the top of the floating valve tower through a pipeline, and the
safety valve group is connected with the pipeline between the
gas phase outlet valve and the floating valve tower through a pipeline; the
noise reduction valve group is connected with a pipeline between the gas phase outlet valve and the
safety valve group through a pipeline, the steam reboiling mechanism and the cooling mechanism are respectively connected with the bottom of the float valve tower through pipelines, the second pipeline is connected with the middle of the float valve tower, and the
nitrogen mechanism is connected to the second pipeline.
