PURPOSE: A detergent composition is provided to have an excellent removal efficiency of contaminants formed on a wet scrubber filler and an electrode of a wet electrical dust collector, to consume a small amount of water necessary for cleaning, and to generate neither re-contamination nor corrosion. CONSTITUTION: A detergent composition comprises a) 1-10 weight% of sodium silicate, b) 20-30 weight% of sodium carbonate or sodium hydroxide, c) 5-15 weight% of surfactant, d) 0.01-10 weight% of diethylene triamine pentaacetic acid, and e) the residual amount of water. The surfactant is an anion surfactant represented by Chemical formula 1, herein, R1, R2 and R3 are, respectively, hydrogen, or C1-18 alkyl or alkenyl, R4 is C2-18 alkylene, a is 0-10, and M is metal, amine or ammonium. |
