New technology for the recovery of heat exchangers

Abstract

The article is devoted to a new method for cleaning heat exchangers. Electrohydraulic technology, is one of the most effective methods of cleaning deposits on the surface of heat-exchange pipes. The principle of the installation is based on the use of the shock wave effect, which occurs when a high-voltage discharge in a liquid is called electro-hydraulic effect. The parameters of the method for cleaning heat exchangers are proposed. Methods for cleaning pipes of complex shape are considered. The results obtained are of interest, both from a scientific and a practical point of view. The electrohydraulic unit is designed for cleaning internal cavities of metal pipelines (bundles of heat exchanger tubes, boilers, boilers, condensers, separate sections of main pipelines, etc.) from solid process deposits. With the appropriate modification of the plant can be used for cleaning metal structures from solid non-metallic deposits (cast parts from the residual molding mixture), cleaning sewage pipes, filters at water intakes.
