Tangential introducing spiral-flow type gas-liquid mixing efficient atomization nozzle

Abstract

The invention discloses a tangential introducing spiral-flow type gas-liquid mixing efficient atomization nozzle which comprises a feeding chamber, a spiral flow chamber and a spray head. The feeding chamber is composed of two layers of coaxial cylinders. A cavity formed by the inner cylinder is a gas channel, and a cavity formed by the outer cylinder is a liquid channel. The feeding chamber and the spiral flow chamber are connected through a flange body. The spiral flow chamber is composed of a spiral flow cavity and four flow guide bodies. The spiral flow chamber is connected with the spray head, the interior of the spray head is divided into a contraction section, a throat and an expansion section, the contraction section communicates with the spiral flow cavity, a gradually contraction hole outlet of a conical gas spray device is right opposite to an annular groove in the inner wall of the contraction section of the spray head, and the atomization effect can be improved. The middle of the contraction section is provided with a vibration leaf spring. The two ends of the throat are in smooth connection with the contraction section and the expansion section correspondingly. Liquid is introduced into the spiral flow chamber to be accelerated and then mixed with accelerated gas in the conical gas spray device for atomization, atomized liquid droplet particles are cut and scattered through the vibration leaf spring, atomization is intensified, liquid is sprayed out from the expansion section of the nozzle, and the contact area is increased.

Description

technical field [0001] The invention relates to a tangentially introduced swirl-flow gas-liquid mixing high-efficiency atomizing nozzle, which is suitable for atomizing two media of gas and liquid. The invention belongs to the technical field of gas-liquid mass transfer. Background technique [0002] Atomizing nozzle is a device that disperses liquid into mist. At present, there are many types of nozzles manufactured in my country, but most of them have complex structures, poor stability, easy blockage of nozzles, insufficient mixing of gas and liquid, and inability to use The problem of finer atomized particles not only affects the quality of the equipment but also greatly reduces the work efficiency. [0003] Atomizing nozzles are widely used in dust suppression, workshop humidification, spraying, household showers and other fields. At present, they are commonly used to settle dust. In order to improve the efficiency of settlement, it is necessary for the atomized particle...
