For tube furnace tube carbonization slag or coking, the usual cleaning methods include physical cleaning and chemical cleaning.
The so-called physical cleaning is the use of mechanical force to break the carbon residue accumulated in the pipeline, and then use the high-speed airflow to blow the debris out to make the pipeline unblocked. Chemical cleaning is to destroy the structure of the carbon residue or react with the carbon residue through a chemical reaction to achieve the purpose of cleaning the residue. Due to the characteristics of the tube furnace, the internal pipes are connected by 180° stamping elbows. If physical cleaning is used, the cleaning distance at a time is limited. It is necessary to open multiple doors to the furnace tube inside the tube furnace, clean it section by section and then weld it section by section, and then use high-speed airflow to blow. The cleaning time is long and very inconvenient. The chemical cleaning method using aerated gasification combustion requires only openings at the inlet and outlet of the oil-rich pipeline outside the tube furnace, which can be cleaned at one time, and there is no need for multiple openings to repair welding, saving labor and time. Since the gasification and combustion are complete, the cleaning is also very thorough.
Manufacturers using tube furnaces can reasonably choose cleaning methods based on specific conditions. Generally speaking, if the tube is relatively long, it is not recommended to use a brush. It can be cleaned by chemical methods. You can burn it in the air for 2 hours (about 800℃). If there is residue, then use chemical methods according to the nature of the residue. Remove.
