Abstract

The invention provides an automatic deslagging device of a pipeline, a heat exchanger pipe and a self-cleaning method, in particular to an automatic deslagging device capable of achieving self cleaning for an air preheater. The automatic deslagging device comprises a rotary deslagging mechanism and a cleaning mechanism. The outer edge of the rotary deslagging mechanism is matched with the inner diameter of the pipeline and rotates under the driving of fluid in the pipeline so as to deslag the inner wall of the pipeline. The cleaning mechanism is used for cleaning the rotary deslagging mechanism and/or the inner wall of the pipeline so as to solve the technical problems that in the prior art, furnace shutdown for deslagging is needed, a spiral device is prone to being abraded, or the cleaning cleanliness is not enough.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to an automatic slag removal device for pipelines, a heat exchanger tube for automatic slag removal and a self-cleaning method. Background technique [0002] At present, gas-fired boilers in iron and steel plants mainly use blast furnace gas, coke oven gas, and converter gas as fuel. After the gas is burned in the furnace, it is discharged to the atmosphere after heat exchange through the air preheater pipeline. Because the gas contains more or less impurities, its main components are dust, sulfide, nitrogen oxides, etc. When these impurities flow through the air preheater pipeline, they will adhere to the inner surface of the pipeline, and the equipment will gradually increase after long-term operation, so that the air preheater pipeline will be blocked, resulting in a decrease in heat exchange capacity and a decrease in boiler thermal efficiency. [0003] The common pra...
