VIBRATION EXCITER Russian patent published in 2006 - IPC F15B21/12 

FIELD: heat engineering.

SUBSTANCE: invention is designed to prevent formation of salt deposits on working heating surfaces of different heat exchange devices. Proposed vibration exciter, mainly for metal structures of heat exchangers, has air duct in form of vertical cylinder with branch pipe to fed compressed air with holes to let out compressed air, wave guide rigidly connected with object to be excited and engaging with striker member arranged in air duct, and air discharge valve. Air duct is made of diamagnetic material and is provided with winding from outer side connected to pulse current source. Valve has contact to switch on pulse current source when striker member is in upper position.

EFFECT: reduced overall dimensions of device, enlarged operating capabilities.
