Bubble atomizing nozzle and adjustment method of bubble atomizing nozzle

Abstract

The invention relates to a bubble atomizing nozzle and an adjusting method of the bubble atomizing nozzle. The bubble atomizing nozzle comprises a multi-channel air intake structure consisting of two or more layers of sealing rings, or an external part of an air intake structure of a swirl groove, and an external part having a diffusion conical spray hole, a jackscrew hole and an air-liquid inlet quick mounting joint, wherein the internal part is directly inserted in the external part to assemble the nozzle; the internal part and the external part are sealed by an O-shaped rubber ring and fixed by a jackscrew; and a space between the internal part and the external part is a mixing chamber. The flowing resistance of the internal part is lower, so that the pressure of the mixing chamber can be kept in a higher range, and the atomizing efficiency of the nozzle is higher; a bubble flow formed in the air-liquid two-phase mixing process in the mixing chamber is uniform and stable, so that the stable atomizing effect is realized under the low-air-liquid mass flow ratio (between 0.07-0.1); and the working pressure is low, and the liquid flow is low, so that the stable atomization can be kept under the liquid flow of 3.5-6.0 kg / h and the absolute air-liquid inlet pressure of 0.36-0.40 MPa. The bubble atomizing nozzle is applied to such fields as chemical engineering, motive power and heating and ventilation.

Description

technical field [0001] The invention relates to a bubble atomization nozzle and a method for adjusting the bubble atomization nozzle, specifically, a low-pressure and small-flow bubble atomization single-hole nozzle with compressed air and water as the working medium, which can be used in chemical industry, power, HVAC and other industries It is a low-pressure air bubble atomizing nozzle with low air consumption rate, stable atomization and high atomization quality during medium humidification and cooling. Background technique [0002] Liquid atomization technology has a wide range of applications in agriculture, chemical industry, energy, transportation and other fields. The atomized liquid is in the form of dispersed particles, so its surface area increases, which is conducive to improving the heat transfer and mass transfer conditions between the gas-liquid two phases. Bubble atomization appeared at the end of the last century. Its principle is to enhance the atomization...

AI Technical Summary

Problems solved by technology

The cross-section of the upper part of the inner mixing chamber is circular, and the overall structure is a narrow and long circular cylinder. Therefore, when the gas-liquid two-phase flow flows through this area, the flow loss is relatively large, which increases the atomization energy consumption of the nozzle.
