Description
Technical field
The utility model belongs to the spraying equipment technical field, relates to a kind of atomizer, especially relates to a kind of liquid gas two phase atomizers.
Background technology
Atomizer is a kind of can the atomization of liquid ejection, and evenly is suspended in airborne device.Its operation principle is through internal pressure; The liquid of inside is squeezed in the nozzle, and nozzle interior is placed with the nozzle core of a similar iron plate, and swiftly flowing liquid knockout is on nozzle core; The bounce-back back forms atomizing particle, and the atomizing particle of generation is through the jet expansion ejection.Because its good atomized spray effect, atomizer is widely used in many industries and fields such as plant protection, the making of air-conditioning temperature-reducing, and even location on a large scale.Along with air-polluting is on the rise, it is outstanding unusually that environmental protection problem seems, atomizer in the utilization in environmental protection, spray for dust suppression field more and more widely.But because the restriction of technical conditions, not only the atomizing particle diameter is bigger for existing atomizer, and the distribution of spraying is inhomogeneous, and because the mixing of liquids and gases is abundant inadequately, and spray orifice often has droplet and drips when spraying, and atomizing effect is not good simultaneously.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example, the Chinese patent document discloses a kind of atomizer [application number: 200910100510.5], comprises nozzle core, is arranged on nozzle core anterior front nozzle cover and valve; Said front nozzle is covered with preceding cavity; Have nozzle bore in the cavity before said, said nozzle core has inlet opening and air admission hole on the surface, and said inlet opening communicates with preceding cavity; Said air admission hole links to each other with valve; The front end of said valve is a broadening formation, and said valve front end sleeve is connected in the nozzle bore, leaves the slit that liquid is flowed out between said valve front end and the nozzle bore.
Such scheme has improved prior art to a certain extent, and gas and liquid are fully mixed, and has avoided liquid to drip from nozzle bore.But this nozzle arrangements is complicated, not only exists the atomizing particle diameter bigger, the uneven defective of the distribution of spraying, and also formed atomized liquid is unstable, and atomizing effect is poor.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, can make gas fully mix, reduce the good liquid gas two of diameter, the atomizing effect of atomizing particle atomizer mutually with liquid.
For achieving the above object; The utility model has adopted following technical proposal: this liquid gas two phase atomizers, comprise fluid chamber, air chamber, hybrid chamber and spray orifice, and described fluid chamber and air chamber all communicate with hybrid chamber; Described hybrid chamber communicates with spray orifice; On fluid chamber and air chamber, be respectively equipped with liquid inlet and gas access, described spray orifice outer end is provided with diffusion tip, and described diffusion tip is connected with spray orifice and communicates.
In above-mentioned liquid gas two phase atomizers, described spray orifice is a circular configuration, and described diffusion tip is that a truncated cone-shaped structure and a less end end face are connected with spray orifice.
In above-mentioned liquid gas two phase atomizers, described fluid chamber is arranged on the outside of air chamber.
In above-mentioned liquid gas two phase atomizers, described gas access is located on the end face of air chamber away from spray orifice one end, and described liquid inlet is located on the side of fluid chamber.
In above-mentioned liquid gas two phase atomizers, described air chamber is a cylindrical structural.
In above-mentioned liquid gas two phase atomizers, described fluid chamber is an annulated column shape structure.
In above-mentioned liquid gas two phase atomizers, described hybrid chamber is the truncated cone-shaped structure, and the end face of the end that hybrid chamber is bigger communicates with fluid chamber and air chamber, and the end face of the end that hybrid chamber is less communicates with spray orifice.
In above-mentioned liquid gas two phase atomizers, the longitudinal center line of described fluid chamber, air chamber, hybrid chamber, spray orifice and diffusion tip overlaps.
Compared with prior art; The advantage of this liquid gas two phase atomizers is: reasonable in design, simple in structure; The structure that fluid chamber and air chamber communicate with hybrid chamber; Gas and liquid are fully mixed in hybrid chamber, be arranged on the diffusion tip of spray orifice front end, can reduce atomizing particle diameter, reach better atomizing effect.
