FIELD: heat power engineering; housing and communal services and different branches of industry. SUBSTANCE: the invention presents a method of pneumoimpulsive purification of an inside surface of the heating systems and vessels of the complex form and may be used in the heat power engineering, housing and communal services and different branches of industry. The offered method and device solve the problem to increase effectiveness and productivity of the process of purification of the heating systems of industrial and household buildings. To have such a technical results the offered method of pneumoimpulsive purification of an inside surface of a heating system provides for generation of the shockwaves in the liquid filling the purified heating system, a sharp supply under the high pressure of the compressed air pulses and the following discharge of the polluted liquid, The shockwave in the liquid circulating in the heating system is generated with the help of a compressed air pulse impact through the exhaust cylinder with the separating plunger, excluding penetration of the air into the liquid. For reaching the above technical result a device for pneumoimpulsive purification of an inside surface of a liquid heating system is offered. The device contains a source of compressed air, a pneumopulse oscillator, a branch-pipe. Unlike the well known device the offered device is supplied with the exhaust cylinder with the separating plunger transferring the impact of a pulse of compressed air into a liquid cavity of the heating system. At that the separating plunger is supplied with an axial drainage aperture, and a wall of the cylinder has a compressed air vent. EFFECT: the invention allows to increased effectiveness and productivity of the process of purification of the inside surfaces of the heating systems in industrial and household buildings. 2 cl, 2 dwg
