Two-fluid nozzle device with large adjustment ratio and large adjustment ratio method thereof

Abstract

The invention relates to a two-fluid nozzle device with large adjustment ratio and a large adjustment ratio method thereof. The device comprises a primary atomization component, an atomization gas supply component and a flow adjustment component, wherein the primary atomization component is used for primarily atomizing liquid and is provided with a primarily atomized liquid ejection structure; the atomization gas supply component is used for further atomizing the primarily atomized liquid and is provided with an atomized gas ejection structure, the ejection direction of the primarily atomized liquid ejection structure intersects with the ejection direction of the atomized gas ejection structure so as to facilitate the atomized gas to impact primarily atomized liquid; and the flow adjustment component comprises a reflux channel for liquid before primary atomization in the primary atomization component and a reflux valve which is arranged in the reflux valve. In the method, the nozzle device is utilized to further atomize the liquid particles subject to the primary atomization through gas, partial liquid refluxes before the liquid is subject to the primary atomization, and the required liquid pressure is lower than that of a pressure atomization nozzle.

Description

technical field [0001] The invention relates to a two-fluid nozzle device and its adjustment method, which atomizes liquid by compressed air or pressurized steam. Background technique [0002] The nozzle device is an important part in the field of industrial application. The nozzle device is used in the equipment of many industries to obtain the liquid of fine particles. The gas for fluid atomization is compressed air or steam. [0003] Pressure atomization is usually done by increasing the pressure or using multiple small flow nozzles, but when a large flow is used, the particle size of pressure atomization is still relatively large. Such disadvantages are that due to the high use pressure, the processing technology of the product itself is difficult, the cost is high, and it is easy to wear. The design requirements of the water supply pipeline are high, the construction cost is high, the water pump pressure is high, the power is high, and the operation cost is high. [...

Problems solved by technology

[0003] Pressure atomization is usually done by increasing the pressure or using multiple small flow nozzles, but when a large flow is used, the particle size of pressure atomization is still large

The disadvantage of this is that due to the high pressure used, the processing technology of the product itself is difficult, the cost is high, and it is easy to wear

Water supply pipeline design requirements are high, construction costs are high, water pump pressure is high, power is high, and operating costs are high

[0004] The existing two-fluid nozzle can produce fine particles, but its adjustment ratio is small. The adjustment of the two-fluid nozzle increases the water volume and the air volume. If the air volume is not increased enough, the particle size will also increase at the same time, so the control system is complicated.

In addition, due to the limitation of design space, the adjustment of water volume and gas volume is also relatively small
