Cleaning agent for rotary machine used for conveying blast furnace gas and coke oven gas

Abstract

The invention discloses a cleaning agent for a rotary machine used for conveying blast furnace gas and coke oven gas. The cleaning agent comprises the following components in percentage by mass: 6 to 8 percent of ethoxylated dodecylalcohol, 4 to 5 percent of fatty alcohol-polyoxyethylene ether with 12 to 14 carbon atoms, 11 to 12 percent of nonylphenol polyoxyethylene ether, 15 to 16 percent of sodium dodecyl benzene sulfonate, 7 to 8 percent of sodium hydroxide, 14 to 16 percent of sodium carbonate, 11 to 12 percent of sodium phosphate, 12 to 14 percent of sodium silicate, 7 to 8 percent of sodium tripolyphosphate, 5 to 7 percent of triethanolamine, 1 to 1.5 percent of imidazoline acetate and 0.2 to 0.4 percent of simethicone. The cleaning agent does not corrode equipment and parts, has light environmental pollution, is noninflammable and inexplosive, and is convenient and safe to use.

Description

Technical field [0001] The present invention involves a cleaning agent, which specifically involves a cleaning agent used to clean the caramel and semi -solid granules such as caramel, dust such as caramel and dust on its passage. Background technique [0002] The blast furnace gas, coke furnace gas, or mixed gas medium of the rotating mechanical transport contains a certain amount of caramel, organic matter, and dust.The mixture, the characteristic is the dark brown paste liquid and semi -solid with a special odor. These stains are adhered to the surface and channel wall of the rotating mechanical blades, and other solid particles in the airflow are gradually formed.Due to the existence of dirt, the unit vibrates, the production load decreases, the operating efficiency is not high, and it cannot even run normally.There is currently no effective chemical cleaning agent for clearing the above dirt.The cleaning of the rotating mechanical equipment of the conveying blast furnace gas...

AI Technical Summary

Problems solved by technology

[0002] The blast furnace gas, coke oven gas or mixed gas medium transported by rotating machinery contains a certain amount of tar, organic matter and dust, etc., and its components are mainly aromatic hydrocarbons, free carbon, pitch, ash and sulfur, calcium and magnesium ions The mixture is dark brown paste liquid and semi-solid with special odor. These scales adhere to the surface of rotating machinery blades and channel walls, and capture other solid particles in the airflow, gradually forming hardened deposits , due to the existence of dirt, the unit vibrates, the production load drops, the operating efficiency is not high, and even cannot operate normally

There is currently no effective chemical cleaning agent for removing the above-mentioned dirt

As for the cleaning of rotating mechanical equipment conveying blast furnace gas and coke oven gas, it is generally to shut down and disassemble the machine, and use brushes, rags, scrapers and other physical methods to clean up. This method takes a long time, delays the construction period, and the cleaning effect is not enough. Thorough, and at the same time it is basically impossible to achieve online cleaning
