Air volume uniform distribution system for insulators of wet type electric precipitator

The invention relates to an air volume uniform distribution system for insulators of a wet type electric precipitator. The air volume uniform distribution system comprises the wet type electric precipitator, a sealed air pipeline and the insulators. The sealed air pipeline comprises a plurality of branch pipe openings, wherein each branch pipe opening exactly faces the corresponding insulator, and a manual adjustment butterfly valve is arranged in each branch pipe opening. The air volume uniform distribution system has the advantages that each manual adjustment butterfly valve and a matched pipe are set for the corresponding insulator, the pipes are led to the positions above the insulators one by one, the volume of air which is led to the sealed air pipes can be adjusted to remove the pressure of smoke, after adjustment is accomplished, adjustment does not need to be conducted again in the equipment follow-up operation process only if the equipment performance is stable, the system is simple, and the practic
