Float valve tower cleaning system and cleaning method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of valve tower cleaning equipment, in particular to a valve tower cleaning system and a cleaning method. Background technique [0002] Float valve trays are widely used in petrochemical industry. Float valve trays are commonly used trays, which open many square or circular holes on the tray, each hole has a valve plate, and the gas passes through the valve hole. The valve plate is lifted up and injected in the horizontal direction. When passing through the liquid layer, the gas and liquid two phases form a foam state to conduct heat and mass transfer processes. Since the opening of the valve plate can be changed with the gas speed, the valve plate can be automatically closed under the action of gravity at low gas speed, reducing leakage. Therefore, it has high efficiency, large operation flexibility, good processing capacity, small mist entrainment, long contact time, good mass transfer effect; and simple s...

Problems solved by technology

[0005] The beneficial effects of adopting the technical solution of the present invention are: by cleaning the floating valve tower, the impurities in the tower are removed, the heat transfer effect of the tray is improved, and the system operation is prevented from being affected by the liquid flooding caused by the large pressure difference of the floating valve tower. Dismantling and cleaning of the tower tray shortens the inspection and maintenance time; ensures the high efficiency of the float valve tower, large operating flexibility, good processing capacity, and good mass transfer effect, and solves the problem of internal impurities accumulated after the float valve tower has been operated for a long time, causing the float valve to be stuck Astringent, dirty trays, affect heat transfer effect, and reduce processing capacity
