Description
Technical field
The present invention relates to a kind of vortex street atomizer, belong to environmental protection depositing dust, spraying equipment technical field such as agricultural spray medicine, the micro-above-water method of fire-fighting etc.
Background technology
At present; the dust of below the 10um particle diameter produced in industrial processes; be difficult to natural subsidence; not only the healthy of workman is had a strong impact on; also can cause dangerous dust explosion; simultaneously along with air-polluting is on the rise, atomizer is in environmental protection, and the utilization in spray for dust suppression field is also more and more extensive.But due to the restriction of technical conditions, the poor effect of the drop absorption respirable dust after existing nozzle atomization.A large amount of agricultural chemicals all will spray every year in China, improves agricultural chemicals to the deposit efficiency of crop, can reduce the formulation rate of agricultural chemicals, reduce environmental pollution.Micro-above-water method technology also needs to improve water smoke to the attachment of comburant, improves the efficiency of fire extinguishing.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses a kind of liquid gas two-phase atomizer [application number: 201220000554.8], comprise fluid chamber, air chamber, hybrid chamber and spray orifice, described fluid chamber and air chamber all communicate with hybrid chamber, described hybrid chamber communicates with spray orifice, fluid chamber and air chamber are respectively equipped with liquid inlet and gas access, and described spray orifice outer end is provided with diffusion tip, and described diffusion tip is connected with spray orifice and communicates.
Such scheme improves prior art to a certain extent, and gas and liquid can be made fully to mix, and diffusion atomizing effect is also better.But this liquid gas two-phase atomizer does not clash into atomization, can not form vortex street water smoke.The effect of the drop absorption respirable dust after atomization is poor, and atomizing effect is not very desirable.Such scheme can improve pesticide droplet and drip adhesive rate to comburant to crops, the micro-water smoke of fire-fighting.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of vortex street atomizer, and it can make gas-liquid two-phase fully mix, reduce the diameter of atomizing particle, form atomization vortex street, and drop that shock be atomized can be made with anion, the adhesive ability of raising droplet.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of vortex street atomizer, and it comprises:
Nozzle body;
Venturi tracheae, venturi tracheae is arranged in nozzle body, and the venturi section of venturi tracheae has liquid phase inlet hole;
Air inlet, air inlet is connected on nozzle body, and air inlet is connected with the import of venturi tracheae;
Inlet, inlet is also connected on nozzle body, and inlet is connected with the liquid phase inlet hole of venturi tracheae;
Shower nozzle, nozzle connecting is connected on nozzle body, and shower nozzle is connected with the outlet of venturi tracheae;
Impact head, impact head is arranged on the exit of shower nozzle, and forms atomized spray passage between the outlet of shower nozzle and impact head.
Further, impact head is connected with shower nozzle by some connecting rods, forms atomized spray passage between connecting rod.
Further, contraction-like gradually in impact head direction of some connecting rods.
Further in order to produce the Karman vortex street phenomenon causing atomization well, dispersing head is frustum cone structure.
Maximum making a concerted effort is reached when spraying further in order to be conducive to, just can reach higher jet velocity and atomizing effect without the need to too high pressure when this vortex street atomizer is worked, the longitudinal center line of air inlet, nozzle body, shower nozzle, venturi tracheae and impact head is on same straight line.
Make nozzle body have very strong yield strength and good wearability further, nozzle body is made up of SUS303 stainless steel.
Further in order to enable shower nozzle high temperature resistant, shower nozzle is made up of carbofrax material.
Further, the inner passage of inlet and/or air inlet is cylindrical channel.
After have employed technique scheme, the intermediate gas flow path of nozzle body is designed to venturi tracheae, when gas is through venturi section, gas flow rate reaches maximum, static pressure is minimum, now venturi place can produce a pressure reduction, this pressure reduction is as the external suction of venturi upper liquid, passed through liquid phase inlet hole and sucked venturi tracheae, now liquid mixes with Vigorous gas, and because gas velocity is greater than liquid velocity, gas-liquid produces huge friction and shear action, liquid is drawn as the elongated silk of a rule, and liquid is by primary atomization; Break the droplet of line along with air-flow is along the air flue of nozzle body to spray outlet accelerated motion, has formed minute bubbles, when bubble arrives exit, external pressure reduces suddenly, and a large amount of air bubble expansion breaks, and produces cavitation phenomenon, it is torn the destruction of droplet continuation around, liquid secondary-atomizing; After gas-liquid impingement after secondary-atomizing to impact head, droplet clashes into atomization again, achieve three atomizations of liquid, it can make gas-liquid two-phase fully mix, and reduces the diameter of atomizing particle, forms atomization vortex street, and drop that shock is atomized can be made with anion, the present invention is suitable for environmental protection depositing dust, agricultural spray medicine, the micro-above-water method of fire-fighting, improves droplet to the adhesive ability of dust, crops, comburant, thus increases work efficiency.
