Abstract

The invention relates to a cleaning device and method used for high-temperature heating face scale of a power station boiler. The device comprises an inlet collection box, an inlet pipeline, a scale cleaning device, a front bend, a rear bend, an outlet pipeline and an outlet collection box which are sequentially communicated in the working medium flowing direction; the scale cleaning device is arranged in an inclined manner, and comprises a scale discharging segment, a channel isolation plate, a scale discharging control door and a scale cleaning device body, the scale cleaning device body isinternally of a cavity structure, the scale discharging segment is communicated with the scale cleaning device body, the scale discharging control door is arranged on the scale discharging segment, the channel isolation plate is arranged in the scale cleaning device body, the channel isolation plate divides the scale cleaning device body into a cleaning device inlet channel and a cleaning device outlet channel, the cleaning device inlet channel is communicated with the cleaning device outlet channel, the cleaning device inlet channel is communicated with the inlet pipeline, and the cleaning device outlet channel is communicated with the front bend. Scale discharging is facilitated, and blockage is avoided.

Description

technical field [0001] The invention relates to a device and method for removing oxide scales on high-temperature heating surfaces of power station boilers, in particular to a device and method for removing oxide scales on high-temperature heating surfaces of super (super)critical units in power stations. Background technique [0002] The problem of overheating and even overheating tube burst caused by the peeling off of the inner wall of the high-temperature furnace tube of the super (ultra)critical unit boiler in the power station and the deposition on the bottom of the elbow is one of the main problems that plague its safe and economical operation in recent years. The oxide layer on the inner wall of the high-temperature heating surface falls off and accumulates at the bottom of the U-shaped bend, which reduces the flow section of the pipe and increases the flow resistance of the steam. The steam flow in the pipe is relatively reduced, which seriously weakens the cooling e...
