Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, an atomizing nozzle applied to a dust suppression device includes a nozzle body 1, a water inlet 2 is disposed at a tail end of the nozzle body 1, and a nozzle 3 is disposed at a front end of the nozzle body 1. The shower nozzle body 1 is cylindrical and its inside intake antrum 4 that forms, is equipped with columniform chamber 5 that admits air in the intake antrum 4, and the chamber 5 that admits air sets up along the central axis of shower nozzle body 1 and just right mutually with nozzle 3, and the both ends of admitting air chamber 5 link up and its tail end outwards stretches out and constitute air inlet 6, front end and constitute gas outlet 7, and water inlet 2 and air inlet 6 are used for connecting the high pressure water pipe and the high-pressure tuber pipe of laying in the feed bin respectively. The nozzle 3 is in a conical cylinder shape, the front end of the nozzle 3 is provided with the spray hole 8, the spray hole 8 comprises a central hole 801 and six side holes 802, the side holes 802 are uniformly distributed in an annular shape around the central hole 801, the central hole 801 is in a reducing hole structure, the rear section of the central hole is a cylindrical hole, the front section of the central hole is a horn-shaped hole, the aperture of the side holes 802 is the same as that of the rear section of the central hole 801, and jet flow can be better broken into water mist after being sprayed out from the spray hole 8. A circular baffle 9 is arranged right in front of the nozzle 3, and the baffle 9 is fixedly connected with the nozzle 3 through two oppositely arranged fixing rods 10, so that the liquid film and the jet flow are further dispersed to form water mist in the process of colliding with the baffle 9. In order to bear large water pressure, the nozzle body 1 can be made of metal materials such as copper, stainless steel and the like.
The working principle of the utility model is as follows:
the utility model discloses atomizer's atomization process divide into three stage. In the first stage, high-pressure water and high-pressure air are respectively pressed into the nozzle body 1 through the water inlet 2 and the air inlet 6, and due to the large pressure and the structure that the wide-caliber of the nozzle 3 enters and the narrow-caliber of the nozzle 3 exits, the liquid at the position of the nozzle hole 8 bears large pressure, and energy is accumulated for subsequent water flow injection. In the second stage, when the water flow just jets out from the jet holes 8 and does not contact the baffle 9, most of the liquid overcomes the surface tension to form water mist under the action of high-pressure air due to the fact that the pressure of the liquid is high and the air outlet 7 of the air inlet cavity 5 faces the jet holes 8. In the third stage, part of the liquid is not completely atomized after being sprayed out of the spray holes 8 to form jet flow, and the high-speed jet flow collides with the baffle 9 to further atomize the liquid after impacting and rebounding to form atomized particles. Finally, the water mist and the dust particles are contacted and collided with each other, so that the dust particles are bonded with each other, condensed and enlarged, and settled under the action of self gravity, thereby effectively achieving the effect of dust suppression.
