Description

A three-tube atomizing nozzle

technical field

The utility model relates to a novel atomizing nozzle, in particular to a three-tube atomizing nozzle.

Background technique

Bubble atomization is a new type of pneumatic atomization method. It injects compressed air into the liquid in an appropriate way, and makes the two form a stable bubble-like two-phase flow in the nozzle mixing chamber. In a short distance, due to the drastic change of the pressure difference between the inside and outside of the bubble, it will expand rapidly until it bursts, thereby further breaking the liquid film wrapped around it into finer liquid mist particles. Because the air consumption of bubble atomization is small, the atomization quality is high, and the atomization effect is basically not affected by the outlet diameter, it is more suitable for atomizing heavy, residual oil and other high-viscosity liquid fuels. The utility model is a three-tube atomizing nozzle designed based on the atomization method.

Utility model content

Based on the bubble atomization method, the utility model provides a three-tube atomization nozzle, which overcomes the disadvantages of low atomization efficiency of the traditional atomization method. The technical scheme adopted is as follows:

A three-tube atomizing nozzle, including a swirl sheet, an external air pipe, a screw, an internal delivery pipe, an internal air pipe, and a gasket. The inside of the pipe is tangent, the external air pipe is sleeved on the internal delivery pipe and fixed by six screws, the internal delivery pipe is sleeved on the internal air pipe and fixed by six screws, the gasket clamp Between the inner delivery pipe and the flange of the inner air pipe.

Preferably, the swirl vane has 26 blades in total, the blade height is 30mm, and the swirl vane is made of high-strength alloy.

Preferably, the gasket is an asbestos rubber sheet gasket.

The utility model has the following advantages:

1) It can achieve the purpose of uniform atomization and improve the efficiency of atomization;

2) It has the advantages of compact structure, long life, reliable use, etc., can withstand high pressure, low noise and small impact.

Detailed ways

Below in conjunction with accompanying drawing and example the utility model is described further:

As shown in Fig. 1 and Fig. 2, a three-tube atomizing nozzle of the utility model includes a swirl sheet 1, an external air pipe 2, a screw 3, an internal delivery pipe 4, an internal air pipe 5, a gasket 6, a swirl The piece 1 is installed on the inner delivery pipe 4, the outer side of the swirl piece is tangent to the inner side of the outer air pipe 2, the outer air pipe 2 is set on the inner delivery pipe 4 and fixed by six screws, and the inner delivery pipe 4 is set inside The air pipe 5 is fixed and installed by six screws, and the gasket 6 is sandwiched between the internal delivery pipe 4 and the flange of the internal air pipe 5 .

The swirl sheet 1 has 26 blades in total, the blade height is 30mm, and the swirl sheet is made of high-strength alloy. Gasket 6 adopts asbestos rubber plate gasket.

The high-speed compressed air is introduced through the external air pipe 2 and the internal air pipe 5, and the heavy oil and other fluids are passed through the internal delivery pipe 4. During work, the compressed air passing through the internal air pipe 5 first crushes the heavy oil and other fluids Fine droplets are initially atomized, and then the compressed air passing through the external air pipe 2 forms a swirl flow through the swirl sheet 1 for secondary atomization to make the atomization effect more sufficient.
