Angular blowing spray nozzle used for condensing evaporator

Abstract

The invention discloses an angular blowing spray nozzle used for a condensing evaporator. The angular blowing spray nozzle comprises a spray nozzle body and a spray nozzle core. A fluid inlet, a spraynozzle hole and a fluid outlet are formed in the spray nozzle body in the axial direction in sequence and communicate with one another coaxially. The spray nozzle core is arranged in the spray nozzlehole, and two rotary runners are formed between the spray nozzle core and the inner wall of the spray nozzle hole, so that fluid entering the two rotary runners is sprayed out of the fluid outlet inthe shape of conical thin film under the effects of high pressure and rotating. The angular blowing spray nozzle has the efficient atomizing effects of large spray speed, large atomizing angle and uniform spraying, and therefore, the evaporator is fast and efficiently cooled.

Description

technical field [0001] The invention relates to the technical field of nozzles, in particular to an angle-blown nozzle for a condensation evaporator. Background technique [0002] Existing nozzles for condensing evaporators, such as the patent titled the nozzle of the fan-shaped jet (the notification number is CN205288742U), have a complex structure, a large amount of material and complex processing techniques. The cooling efficiency of the existing technology is low, which is mainly reflected in the fact that a large atomization angle cannot be guaranteed under the condition of a certain spray speed, and the spray energy of the spray droplets is relatively concentrated, which will cause a phenomenon of long range but narrow distribution, which will affect the spray range; If the atomization angle is too large, although the distribution surface of fog particles will increase, its effective range will be greatly reduced and the distribution of fog particles will be uneven.

[0002] Existing nozzles used for condensing evaporators, such as the patent titled the nozzle of the fan-shaped jet (the notification number is CN205288742U), have a complex structure, a large amount of material and complex processing techniques.

The cooling efficiency of the existing technology is low, which is mainly reflected in the fact that a large atomization angle cannot be guaranteed under the condition of a certain spray speed, and the spray energy of the spray droplets is relatively concentrated, which will cause a phenomenon of long range but narrow distribution, which will affect the spray range; If the atomization angle is too large, although the distribution surface of fog particles will increase, its effective range will be greatly reduced and the distribution of fog particles will be uneven.

The existing technology cannot effectively ensure the uniform distribution of the pressure field and velocity field at the nozzle outlet, and the spray shape cannot be well controlled in the case of turbulent cooling water flow, resulting in uneven spraying
