Description

Soot cleaning device in the smokestack}

The present invention relates to an apparatus for cleaning soot inside a chimney which removes soot, etc. attached to an inside of a chimney of a large-scale factory or a thermal power plant using large fossil fuels, and the like to perform a smooth flue gas function.

In case of using large-scale fossil fuels such as large factories or thermal power plants that consume a large amount of energy as fuel, the installation of very large and large stacks is essential.

Such stacks are installed at very high altitudes to minimize the air pollution on the surface as a device for blowing smoke generated and discharged when burning fuel to the air.

However, as the stack is used for a long time, smoke particles inside the stack are aggregated and adhered to the stack, thereby blocking the pipeline and inhibiting the flue gas function.

Therefore, it is necessary to periodically clean the inside of the stacks. Such stacks are very high and huge buildings, which is very difficult to manage the facilities. Therefore, each power plant or domestic industry is indifferent to cleaning the inside of the stacks.

The soot in the stack pollutes the surrounding environment, which can lead to complaints, and is pointed out as a problem in terms of environmental regulations and environmental protection that are strengthened around the world.

In addition, even if the inside of the stack is cleaned, the remaining soot becomes a medium as a peak, and the newly created soot rapidly grows into snow, increasing the amount of ejection to the outside. As a result, the effectiveness of cleaning is questionable.

In addition, there is a problem in the safety of the worker because the aerial work must be carried out during the cleaning of the stack, there was a difficulty in the actual work by the worker because it contains a strong acid hazard element among the components contained in the soot.

In the present invention devised to solve such a problem, personnel can work from outside without directly entering the inside of the stack, and clean the stack as in the initial construction by a short, short time, but the air pollution during the cleaning work. It is an object of the present invention to provide an apparatus for cleaning soot inside so that there is little.
