Abstract
The utility model discloses an air-assist atomizing nozzle which comprises a steel pipe and a sprayer. The sprayer is arranged at one end of the steel pipe, the end of the steel pipe is embedded into a sprayer cavity, and a spray hole communicated with the sprayer cavity is formed in the end of one side of the sprayer far away from the steel pipe. The air-assist atomizing nozzle is characterized in that a spoiler is arranged at the front end of the end of the steel pipe embedded into the sprayer cavity, a through hole communicated with a flow guide hole and the spray hole is formed in the spoiler, and an included angle beta is formed between the center axis of the through hole and the center axis of the flow guide hole and is an acute angle. The flow direction of gas-liquid mixtures passing the flow guide hole is changed by the spoiler, the gas-liquid mixtures move forwards in an accelerating manner by the aid of the through hole in the spoiler, so that the gas-liquid mixtures can be atomized for the first time, the gas-liquid mixtures are atomized for the second time when sprayed out by the spray hole, and the atomization coefficient of the obtained gas-liquid mixtures is high.
Description
Technical field
The utility model relates to a kind of gas and helps formula atomizer, and especially a kind of gas-liquid mixed gas effective, that atomization coefficient is high helps formula atomizer.
Background technology
The atomizer of domestic frequent use at present is mainly comprised of nozzle and steel pipe two parts, the perforate of steel pipe core, steel pipe one end is embedded in the cavity of nozzle interior, on a side end face away from steel pipe on this nozzle, be provided with spray-hole, the hole UNICOM of this spray-hole and steel pipe core, because nozzle inside diameter is far smaller than the diameter in the hole of steel pipe core, thereby the liquid of gas-liquid mixed is atomization ejection when spray-hole sprays.But in reduction of nitrogen oxide course of reaction, because the atomization coefficient of the gas-liquid mixture by spray-hole is still on the low side comparatively speaking, therefore exist and easily in spray-hole position, form crystallization, thereby the problem of obstruction spray-hole affects the normal operation of system.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gas and helps formula atomizer, has the advantages that gas-liquid mixed is effective, atomization coefficient is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of gas helps formula atomizer, comprise steel pipe and shower nozzle, described steel pipe core has the pod apertures connecting along its axis direction, described steel tube end part is embedded in shower nozzle cavity, and shower nozzle is welded in steel tube end part, described shower nozzle is provided with the spray-hole that penetrates into shower nozzle cavity on the end away from steel pipe one side, described nozzle inside diameter is much smaller than shower nozzle cavity internal diameter, its innovative point is: described in the steel tube end part front end that is embedded in shower nozzle cavity be provided with a spoiler, described spoiler cross section is consistent with shower nozzle cavity cross section, on described spoiler, have the through hole that connects pod apertures and spray-hole, described through-hole diameter is much smaller than shower nozzle cavity internal diameter, and between described through hole central axis and pod apertures central axis, angle β is an acute angle.
Further, in described shower nozzle cavity, be provided with positive stop lug boss, described positive stop lug boss is arranged at spoiler front end, and described spoiler is against on positive stop lug boss, and the shower nozzle cavity internal diameter of described positive stop lug boss position is less than the shower nozzle cavity internal diameter of steel pipe position.
Further, between described positive stop lug boss and spray-hole, exist certain distance to form mixing chamber.
Further, described shower nozzle is hemispherical away from the inner wall of end of steel pipe one side.
The utility model has the advantage of: by the steel tube end part front end in being embedded in shower nozzle cavity, be provided with a spoiler, and on spoiler, have a through hole that connects pod apertures and spray-hole, between this through hole central axis and pod apertures central axis, angle β is an acute angle, thereby utilize spoiler to change by the flow direction of the gas-liquid mixture of pod apertures, utilize the through hole on spoiler to play the object that gas-liquid mixture acceleration is advanced, thereby realize the object to the atomization for the first time of gas-liquid mixture, thereby gas-liquid mixture is atomization for the second time while spraying through spray-hole, the atomization coefficient that now obtains gas-liquid mixture is higher.
For further making the gas-liquid mixture after atomization for the first time fully mix, in shower nozzle cavity, be provided with positive stop lug boss, this positive stop lug boss is arranged at spoiler front end, spoiler is against on positive stop lug boss, the shower nozzle cavity internal diameter of this positive stop lug boss position is less than the shower nozzle cavity internal diameter of steel pipe position, now guarantee to exist certain distance to form mixing chamber between positive stop lug boss and spray-hole, thereby utilize mixing chamber fully to mix.
For making gas-liquid mixture not have dead angle in spray-hole position, shower nozzle is to hemispherical away from the inner wall of end of steel pipe one side.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Diagram is the structural representation that a kind of gas of the utility model helps formula atomizer.
In figure: 1-steel pipe, 2-shower nozzle, 3-pod apertures, 4-shower nozzle cavity, 5-spray-hole, 6-spoiler, 7-through hole, 8-positive stop lug boss, 9-mixing chamber.
The specific embodiment
Gas of the present utility model helps formula atomizer mainly to comprise steel pipe 1 and shower nozzle 2.Steel pipe 1 core has the pod apertures 3 connecting along its axis direction, and steel pipe 1 end is embedded in shower nozzle cavity 4, and shower nozzle 2 is welded on steel pipe 1 end.On the end of shower nozzle 2 away from steel pipe 1 one sides, be provided with the spray-hole 5 that penetrates into shower nozzle cavity 4, these spray-hole 5 diameters are much smaller than shower nozzle cavity 4 internal diameters.For increasing by the atomization coefficient of the gas-liquid mixture of spray-hole 5, steel pipe 1 end front end in being embedded in shower nozzle cavity 4 is provided with a spoiler 6, these spoiler 6 cross sections are consistent with shower nozzle cavity 4 cross sections, on spoiler 6, have the through hole 7 that connects pod apertures 3 and spray-hole 5, these through hole 7 diameters are much smaller than shower nozzle cavity 4 internal diameters, and between through hole 7 central axis and pod apertures 3 central axis, angle β is an acute angle.
Adopt said structure, utilize spoiler 6 to change by the flow direction of the gas-liquid mixture of pod apertures 3, utilize the through hole 7 on spoiler 6 to play the object that gas-liquid mixture acceleration is advanced, thereby realize the object to the atomization for the first time of gas-liquid mixture, thereby gas-liquid mixture is atomization for the second time while spraying through spray-hole 5, and the atomization coefficient that now obtains gas-liquid mixture is higher.
For further making the gas-liquid mixture after atomization for the first time fully mix, in shower nozzle cavity 4, be provided with positive stop lug boss 8, this positive stop lug boss 8 is arranged at spoiler 6 front ends, spoiler 6 is against on positive stop lug boss 8, shower nozzle cavity 4 internal diameters of these positive stop lug boss 8 positions are less than shower nozzle cavity 4 internal diameters of steel pipe 1 position, now guarantee that 5 of positive stop lug boss 8 and spray-holes exist certain distance to form mixing chamber 9, thereby utilize mixing chamber 9 fully to mix.
For making gas-liquid mixture not have dead angle in spray-hole 5 positions, shower nozzle 2 is to hemispherical away from the inner wall of end design of steel pipe 1 one sides.
