Pulsating type atomizer

Abstract

The invention discloses a pulsating type atomizer. The pulsating type atomizer comprises an outer pipeline, an inner pipeline and an atomizing nozzle, wherein the outer pipeline and the inner pipelineare arranged in a nesting manner; the outer pipeline is an atomizing medium pipeline, and the inner pipeline is an atomizing working medium pipeline; one end of the atomizing working medium pipelineis positioned into the atomizing medium pipeline and sleeves the atomizing nozzle with the atomizing medium pipeline; and an atomizing working medium and an atomizing medium correspondingly flow froman atomizing working medium channel and an atomizing medium channel to an outlet of the atomizing nozzle and then are injected out. According to the pulsating type atomizer, the atomizing medium and the atomizing working medium act on each other to produce regular pulsating type atomizing air flow, so that regular pressure, flowing and atomizing pulsating processes can be realized while the atomizing effect is ensured; with the adoption of the structure, the pulsating combustion can be achieved without changing a combustion chamber structure; and meanwhile, the pulsating type atomizer is applicable to other fields of utilizing regular atomizing to promote mixing and reinforce heat transfer.

Description

technical field [0001] The invention relates to liquid atomization technology, in particular to a pulse atomizer. Background technique [0002] Liquid atomizer In various industrial equipment, liquid atomization methods include mechanical atomization, ultrasonic atomization, electrostatic atomization and pneumatic atomization. Mechanical atomization is the injection of high-pressure liquid into low-speed gas at a high speed to achieve the effect of atomization. Mechanical atomization is mostly suitable for atomizing substances with low viscosity, such as gasoline, water, etc. Ultrasonic atomization, through the high-frequency oscillation of ultrasonic electrons, disturbs the surface of the liquid, so that the liquid at the peak of the liquid surface is separated and broken, thereby generating atomization. Ultrasonic nebulizer adopts high-efficiency integrated circuit, ultra-small integrated unique structural design, and important components use high-quality atomizing sheet...

Problems solved by technology

This method relies on the coupling of the sound field characteristics caused by the geometric structure of the burner and the combustion characteristics of the burner, and its design and operation control are relatively complicated

Moreover, the thermoacoustic coupling combustion method is mostly suitable for gas burners, and is often not suitable for occasions where the fuel is heavy oil or coal-water slurry
