Abstract

This utility model discloses a venturi atomizer, including venturi tube; the air flow rotational structure which can disturb air flow and generate rotation in the inlet, the inner wall of outlet of venturi tube is provided with two spraying nozzles, the outer side of each spraying nozzle is connected with perfusion tube which is installed outside of venturi tube. The structure of this utility model is simple, the liquid can be effectively atomized no matter whether the gas flow rate is fast or slow, and the atomization is fine.

Description

Venturi scrubber
Technical field
The utility model relates to a kind of atomizer, particularly venturi scrubber that liquid juice is injected into gas pipeline, makes it rapidly atomizing and mix with air-flow of being used for.
Background technology
At present, the normal drive nozzle of being installed that adopts of atomizer carries out pressure atomization to liquid, and its gas pipeline is made turbulent disturbance by the simple geometric shape.But this atomizer is because the bulk of gas pipeline is less, and the jet length of nozzle is shorter, causes the atomizing effect of liquid undesirable.In addition, when air velocity was reduced to a certain degree, the simple geometric shape also was not enough to make turbulent disturbance, so traditional atomizer does not have the effect of atomizing sometimes at all.
The utility model content
The purpose of this utility model is to provide a kind of venturi scrubber, and is not only simple in structure, and no matter the gas flow rate speed can both effectively atomize to liquid, and atomizing effect is good.
The purpose of this utility model is achieved in that a kind of venturi scrubber, comprise Venturi tube, has the air-flow rotational structure that makes flow perturbation and produce rotation in the import of Venturi tube, on the outlet internal perisporium of Venturi tube at least two spray nozzles are being set, all outer with the being arranged on Venturi tube woven hose of the outboard end of each spray nozzle links to each other.
Because the air-flow rotational structure is arranged at the arrival end of Venturi tube, just can make air-flow quicken rotation in the time of in air-flow enters this arrival end, even when air velocity is low, still can keep the stronger disturbance effect of air-flow, simultaneously, Venturi tube plays the effect that improves the air-flow central speed, and produces strong disturbance in the air-flow periphery; A plurality of in addition nozzles are positioned at the Venturi tube outlet, and the liquid of a plurality of nozzle ejection meets at together and clashes into mutually, together just can produce strong atomizing along with swiftly flowing eddy airstream flows.The utility model is by increasing the air-flow rotational structure, the atomizing of atomizer under various working and the effect of mixing have been improved, it is not only simple in structure, and no matter the gas flow rate speed can both effectively atomize to liquid, atomizing effect is good, and the speed of atomizing is higher, and the mixed state of gas and drop is more stable, thereby can also save the injection volume of liquid, increase economic efficiency.

The specific embodiment
A kind of venturi scrubber, as Fig. 1, Fig. 2, shown in Figure 3, comprise Venturi tube 2, has the air-flow rotational structure 1 that makes flow perturbation and produce rotation in the import of Venturi tube 2, as shown in Figure 1 and Figure 2, said air-flow rotational structure 1 is the uniform helical blade that tilts to extend to tube hub that is being provided with on the import internal perisporium of Venturi tube 2.As shown in Figure 4, said air-flow rotational structure 1 is to cooperate suit a cylinder, the uniform tangential swirl groove 8 that is being provided with on the axial inner peripheral surface of cylinder in the import of Venturi tube 2.Even if use this structure can make air-flow when low-speed flow is crossed Venturi tube 2, still can produce the whirlpool disturbance, strengthen atomizing effect; On outlet 5 internal perisporiums of Venturi tube 2 at least two spray nozzles 3 are being set, all outer with the being arranged on Venturi tube woven hose 4 of the outboard end of each spray nozzle 3 links to each other.As Fig. 4, shown in Figure 5, said spray nozzle 3 is 3-6, and each spray nozzle 3 is uniform twist to be arranged on outlet 5 internal perisporiums of Venturi tube 2, and the center line of each spray nozzle 3 is all crossing with the center line of Venturi tube 2.Clash into mutually from the drop of spray nozzle 3 ejections, further strengthen atomizing; Simultaneously, the operating mode effect of the heavy caliber nozzle that a plurality of spray nozzles 3 are more suitable than single total injection volume is good, and especially when the liquid injection volume was tending towards reducing, the adaptability of a plurality of spray nozzles was stronger than single injector.In the port of export center of Venturi tube 2 drop is being set and is dispersing circular cone 6, drop is dispersed the middle part of the tip of circular cone 6 towards Venturi tube 2.Above-mentioned drop is dispersed the downstream that circular cone 6 is positioned at a plurality of spray nozzle 3 joints, direct and its generation bump of central gas stream, improve gas pipeline periphery air velocity, the effect that makes atomizing and mix is strengthened rapidly, avoid drop directly to be brought into the downstream simultaneously by the center high velocity air, thereby prolong travel distance and the holdup time of drop in atomizer, improved atomizing effect, it also can be other block that is positioned at Venturi tube 2 port of export centers, plays bump and deflecting action that drop is dispersed circular cone 6.For preventing that spray nozzle 3 from stopping up, and is installed with filter 7 on the woven hose 4.
In sum, the utility model atomizer combines multiple atomizing principles, than conventional atomizers better atomizing effect is arranged, and especially be fit to change under the operating mode occasion to gas pipeline filling liquid.With high pressure gas pipeline filling ethylene glycol is example, pipe diameter is less, utilization rotation of the utility model atomizer and pressure reduction produce stronger turbulent disturbance, make full use of injection and effect of impact that a plurality of spray nozzles 3 make the liquid generation of being sprayed, and drop disperses bump, compression and deflecting actions that the miscarriage of the 6 pairs of central gas of circular cone is given birth to, makes ethylene glycol atomizing fully rapidly, and not only atomization speed is faster, atomizing effect is more stable, and can save ethylene glycol, have very big economic benefit.
