A Solid Cone Bubble Atomizing Nozzle Suitable for High Viscosity Non-Newtonian Fluids

Abstract

The invention relates to a solid cone-shaped bubble atomizing nozzle suitable for high-viscosity non-Newtonian fluids, which includes an inner interface, an outer interface, a sleeve, a bubble generator, a mixer and a spray head, and the inner interface is fixed on the side of the mixer through the sleeve. One end, the nozzle is fixed on the other end of the mixer, the external interface is fixed on the mixer, and the bubble generator is set in the mixer; the bubble generator includes a guide tube and a guide plate fixed on the guide tube, and the guide plate The inner cavity of the mixer is divided into the outer flow channel and the mixing chamber. One end of the guide tube is connected to the inner interface through the sleeve, and the outer flow channel is connected to the outer interface. There are multiple outer guide holes evenly distributed on the circumference of the guide plate, which are located in the mixing chamber. One end of the indoor guide tube is provided with a plurality of inner guide holes. The invention solves the technical problems of poor nozzle atomization effect, high atomization gas consumption rate and large average droplet size of the existing high-viscosity non-Newtonian fluid. quality.

Description

technical field [0001] The invention relates to a solid-cone bubble atomizing nozzle capable of atomizing non-Newtonian fluids, in particular to high-efficiency atomization of non-Newtonian fluids with high viscosity and complex rheological properties, capable of forming a solid-cone spray field, and can be applied here Atomization and combustion devices for similar fluids.
