The invention discloses an electrically replaced hot water cleaning device for the inner wall of a pipeline. The electrically replaced hot water cleaning device comprises a nozzle short guide pipe, a flow guide nozzle, a nozzle long guide pipe, front rollers, rear rollers, a water supply hose, a hot water header pipe, roller seats, roller elastic shafts, an electric heater case, a water supply plug-in, a power plug-in and a power line. The device is characterized in that the electric heater case is a cylindrical container; an electric heating rod and a temperature control device are arranged in the cylindrical container respectively; the rear end of the cylindrical container is provided with the water supply hose and the power line; the front and rear ends of the cylindrical container are provided with three groups of front rollers and rear rollers; and by adopting a mode of normal temperature high pressure water supplied by a high pressure pump, electrically replaced hot water, oriented injection stream, pipeline inner wall attachment spraying and melting and jet flow propulsion, the inner wall of the pipeline is cleaned to the best effect and the limitation to the length of the pipeline is avoided. The electrically replaced hot water cleaning device belongs to the field of petrochemical pipeline engineering, is compact in structure, good in removing effect, high in efficiency, convenient to operate and easy to implement, has a few easily damaged parts, and can reduce cleaning cost.
