Problems solved by technology

[0002] In the existing vortex ring generating device, the vortex rings are mainly generated intermittently one by one, and the ventilation rate is greatly limited. For the heating or cooling fields with the minimum ventilation rate standard, the vortex ring ventilation rate produced by it cannot meet the requirements.
Moreover, the existing axial disturbance vortex ring device relies on the electromagnet to directly impact and disturb the film, the stroke is limited, and the disturbance effect is not ideal
If the motor is used to drive the screw to impact and disturb the film, it is inconvenient to achieve short-term high-speed and intermittent disturbance, and the continuous change of the direction of the motor makes the performance of the motor unable to maximize. If it is a moving structure, the impact and noise to achieve the above requirements are too large, so it is not the best choice

Abstract

The invention discloses a vortex ring exciter based on pressure loss control. The vortex ring exciter comprises a fan, an air supply main pipeline, cut-off devices, a convergent nozzle and a plurality of opposite-impact cut-off pipelines, wherein the fan is arranged at the inlet end of the air supply main pipeline, the convergent nozzle is arranged at the outlet end of the air supply main pipeline, the plurality of opposite-impact cut-off pipelines are uniformly distributed in the circumferential direction of the air supply main pipeline, an inlet of each opposite-impact cut-off pipeline is in communication with an upper inner cavity of the air supply main pipeline, an outlet of each opposite-impact cut-off pipeline is in communication with a lower inner cavity of the air supply main pipeline, and the cut-off devices are arranged at the inlets of the opposite-impact cut-off pipelines. According to the vortex ring exciter based on pressure loss control, opposite-impact type cut-off of air flow is achieved, reverse air flow of an opposite-impact flow channel is used for replacing an original cut-off plate, and closing and opening of a main flow channel of the air supply main pipe are achieved; and the structure is simpler, the service life of equipment is prolonged, and the quality of produced vortex rings is improved.
