Abstract
The invention discloses an ultra-fine bubble generator which comprises a cavity, a gas inlet, a bubble outlet and a liquid inlet. The ultra-fine bubble generator is characterized in that the cavity is in a heart shape, and a convex part is arranged in the cavity; the gas inlet is positioned on a symmetric axis of the convex part of the inner circle of the cavity; the bubble outlet, the gas inlet and the symmetric axis of the convex part are arranged on the same straight line; and the liquid inlet is arranged in the direction which is tangent with the inner circle of the cavity and is perpendicular to the bubble outlet, the gas inlet and the symmetric axis of the convex part. The invention has simple structure, wide application range, energy saving and low cost.
Description
Technical field
The present invention relates to a kind of bubble generator, is a kind of device that relies on the liquids and gases interaction to produce superfine air bubble specifically.
Background technology
Traditional bubble generator is under external force, relies on the high speed rotation of impeller that gas and liquid are carried out the powerful mixing stirring, and gas breaking is become minute bubbles.The bubble that traditional bubble generator not only produces is excessive, and power consumption is very big, simultaneously because bubble is excessive in liquid the time of staying too short and influence the dissolving of gas.
Application number is that 200610140565.5 Chinese patent discloses a kind of bubble generator, adopt gas-liquid together to add, utilize gas different with density of liquid, the centrifugal force difference that produces when the mixture of the two rotates at a high speed, thereby with bubble and fluid separation applications, this method is because the separation of bubble is relevant with rotary speed, so bubble is big or small inhomogeneous; Fashionablely need other device could work again when adopting gas-liquid to add respectively, this has not only increased cost, and in case the device damage that adds, bubble generator just can not be worked, and makes the scope of application be limited to.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of ultra-fine bubble generator, utilize hydrodynamics and aerodynamic principle, in airtight heart type cavity with flow velocity faster under the water conservancy diversion of liquid at guiding device fast rotational form empty negative pressuren zone, gas is sucked and forms gas column from the gas access, liquid is fast rotational and mobile to the bubble outlet gradually under the water conservancy diversion of cavity inside lug boss in cavity, owing to adopt heart type cavity, end is provided with lug boss in the gas access, the outside at cavity forms the tow-away zone, make liquid to flow in vigor bubble exit, thereby need not add other devices; In the gentle bubble of cavity inside exit, the liquid that fast rotational moves cuts into very trickle bubble with gas, because bubble forms under negative pressure state, the pressure of bubble internal gas is less than the pressure sum of extraneous normal atmosphere (An) and liquid, cause the micro air bubble of generation to continue under external pressure to diminish, finally become superfine air bubble.Concrete scheme is:
A kind of bubble generator comprises cavity, gas access, bubble outlet, liquid inlet,
Described cavity is a heart type, lug boss is arranged in the cavity, described gas access is positioned on the symmetry axis of the round lug boss of cavity, the symmetry axis of described bubble outlet, gas access, lug boss is same straight line, described liquid inlet be arranged on cavity in the tangent direction of circle and vertical with the symmetry axis of bubble outlet, gas access, lug boss.
In order to obtain better technique effect, on the inwall of gas access, be provided with screw thread, described screw thread and screw spin, the arranged outside gas interface of air inlet, the internal diameter of described gas interface is greater than the diameter of gas access; Gas enters cavity along the slit between screw and the screw thread from the outside, has prolonged the path that gas enters cavity like this, makes the air inlet become continuously uniform and stable, thereby the superfine air bubble that the bubble exit is produced is uniform and stable continuously; Can also utilize the gap of air inlet place screw thread and screw to control air inflow, reach the effect of adjusting the air inlet amount.
Advantage of the present invention is: 1. simple in structure; 2. be widely used; 3. energy-conservation; 4. cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a left view;
Fig. 3 is the gas access enlarged drawing.
The specific embodiment
Specify the present invention below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the present invention includes and comprise heart type cavity, gas access 1, bubble outlet 2, liquid inlet 3, in the described heart type cavity lug boss 5 is arranged, described gas access 1 is positioned on the symmetry axis of the round lug boss 5 of cavity, the symmetry axis of described bubble outlet 2, gas access 1, lug boss is same straight line, described liquid inlet 3 be arranged on cavity in circle point of contact 4 and vertical with the symmetry axis of bubble outlet 2, gas access 1, lug boss 5.
As shown in Figure 3, the inwall of described gas access 1 is provided with screw thread 11.Described screw thread 11 spins with screw 12, the arranged outside gas interface 13 of air inlet 1, and the inside diameter D of described gas interface is greater than the diameter d of gas access.
Claims (2)
1. bubble generator, comprise cavity, gas access, bubble outlet, liquid inlet, it is characterized in that: described cavity is a heart type, lug boss is arranged in the cavity, described gas access is positioned on the symmetry axis of the round lug boss of cavity, the symmetry axis of described bubble outlet, gas access, lug boss is same straight line, described liquid inlet be arranged on cavity in the tangent direction of circle and vertical with the symmetry axis of bubble outlet, gas access, lug boss.
