Modular Multi-Line Microjet Nebulizer

Abstract

The invention relates to an atomizer, in particular to a modularization multi-thread micro-jetting atomizer. The modularization multi-thread micro-jetting atomizer is provided with a first jetting nozzle, a second jetting nozzle, a glass pipe, an adapter, a piezoelectric ceramic pipe and a fixing assembly. The first jetting nozzle and the second jetting nozzle are installed at the lower end of the glass pipe, and the periphery of the interior of the first jetting nozzle and the periphery of the interior of the second jetting nozzle are respectively provided with at least two jetting nozzle bodies; the adapter is provided with inner threads and a sealing gasket, installed at the upper end of the glass pipe, connected with a material storage tank filled with materials through the inner threads, and sealed through the sealing gasket; the piezoelectric ceramic pipe is arranged on the lower portion of the glass pipe, arranged on the first jetting nozzle and the second jetting nozzle, and connected with a driver through a wire; the fixing assembly is arranged in the middle of the glass pipe, and used for fixing a power supply wire of the piezoelectric ceramic pipe. As for the high-viscosity materials, the good atomization effect is achieved, blocking is not caused easily, a large number of liquid drops in the same size can be produced, the structure is simple, the manufacturing and maintaining cost is low, and the yield adjustment is flexible.

Description

technical field [0001] The present invention relates to atomizers, and more particularly to a modular multi-line micro-jet atomizer for atomizing high-viscosity liquids and producing droplets of uniform size. Background technique [0002] At present, the known pressure atomizer is mainly composed of a liquid tangential inlet, a liquid swirling chamber and a nozzle (Mujumdar, A.S. Handbook of Industrial Drying, third edition. New York: CRCPress, 2006). It uses a high-pressure pump to make the liquid obtain a very high pressure of 2-20MPa, and the liquid enters the rotary chamber from the tangential inlet, and obtains rotary motion in the rotary chamber. According to the law of conservation of rotational momentum moment, the rotational velocity is inversely proportional to the vortex radius. Therefore, the closer to the axis, the greater the rotation speed and the smaller the static pressure, so that an air swirl flow equal to the atmospheric pressure is formed in the center ...
