Description
Technical Field
The utility model belongs to the technical field of the nozzle, in particular to liquid combustion nozzle.
Background
At present, the liquid burner on the market generally has the problem that the liquid can not be ensured to be fully combusted, so that various liquid combustion nozzle structures exist on the market at present, and the liquid combustion efficiency is improved as much as possible. Most of the nozzles of the liquid burner burn because the initial speed of gas-liquid ejection is too high and the gas-liquid ejection is not completely atomized; secondly, the spray hole distribution range of the existing liquid burner nozzle is small, so that the atomization angle is insufficient, and the atomization effect is general.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a liquid combustion nozzle with a novel structure, thereby it adopts the structural mode of reposition of redundant personnel spheroid and combustible liquid collision deceleration to reduce the initial velocity and improve the atomization quality.
The purpose of the utility model and the technical problem thereof are realized by adopting the following technical scheme. According to the utility model provides a liquid combustion nozzle, including the nozzle outer tube, suit in the nozzle inner tube of nozzle outer tube inside, form the air current passageway between nozzle outer tube and the nozzle inner tube, the nozzle inner tube includes combustible liquid import pipeline section, venturi section, the combustible liquid export pipeline section that communicate in proper order, and the pipe internal diameter of combustible liquid import pipeline section is greater than combustible liquid export pipeline section; the outlet end face of the nozzle outer pipe is provided with a plurality of spray holes distributed in an annular array, a shunting ball body is fixedly arranged in a mixing chamber formed between the outlet end face of the nozzle outer pipe and the combustible liquid outlet pipe section, and the shunting ball body is arranged right opposite to the outlet of the nozzle inner pipe.
The purpose of the utility model is further realized by adopting the following technical measures.
The foregoing liquid combustion nozzle wherein the diameter of said splitter sphere is equal to the diameter of the throat of said venturi section.
Borrow by above-mentioned technical scheme, the utility model discloses a mode that high-speed spun combustible liquid collided each other in reposition of redundant personnel spheroid and the nozzle inner tube reduces combustible liquid initial velocity, and then from each orifice blowout under reposition of redundant personnel spheroidal sphere guide effect, has not only reduced whole nozzle blowout combustible liquid initial velocity, has improved the atomization quality, has still guaranteed great atomizing angle.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 2, a liquid combustion nozzle of the present invention includes an outer nozzle tube 1 and an inner nozzle tube 2 sleeved inside the outer nozzle tube 1, and an air flow channel 3 for compressed combustion-supporting gas to pass through is formed between the outer nozzle tube 1 and the inner nozzle tube 2. The nozzle inner pipe 2 comprises a combustible liquid inlet pipe section 21, a Venturi pipe section 22 and a combustible liquid outlet pipe section 23 which are sequentially communicated, and the inner diameter of the combustible liquid inlet pipe section 21 is larger than that of the combustible liquid outlet pipe section 23, so that the combustible liquid is accelerated. The outlet end face of the nozzle outer tube 1 is provided with a plurality of spray holes 4 distributed in an annular array, and a mixing chamber 5 formed between the outlet end face of the nozzle outer tube 1 and the combustible liquid outlet pipe section 23 is internally and fixedly provided with a shunting ball 6. The shunting ball body 6 is fixed on the outlet end face of the nozzle outer tube, and the shunting ball body 6 is arranged right opposite to the outlet of the nozzle inner tube 2; the axis of the shunt sphere 6 coincides with the axis of the nozzle inner tube 2 to ensure that the combustible liquid sprayed out of the nozzle inner tube evenly impinges on the shunt sphere. Preferably, the diameter of the splitter sphere 6 is equal to the throat diameter of the venturi section 22.
The working principle of the utility model is as follows:
when the jet nozzle works, compressed combustion-supporting gas is introduced into the airflow channel 3 between the inner pipe and the outer pipe of the jet nozzle, combustible liquid is introduced into the inner pipe 2 of the jet nozzle, the combustible liquid enters the Venturi tube section 22 through the combustible liquid inlet tube section 21 to realize acceleration, and the inner diameter of the tube of the combustible liquid inlet tube section 21 is larger than that of the combustible liquid outlet tube section 23, so that the combustible liquid is jetted out from the inner pipe outlet of the jet nozzle at a high speed, the liquid in the range of the flow dividing sphere directly impacts the flow dividing sphere 6, and part of the combustible liquid radially diffused from the outlet of the combustible liquid outlet tube section 23. The splitter sphere 6 not only reduces the initial velocity of the combustible liquid when it is sprayed out from the spray holes 4, but also guides the combustible liquid so that it is sprayed out from the spray holes 4 distributed in a circular array as uniformly as possible. As shown in figure 2, the utility model discloses set up the orifice that multilayer annular array distributes, increased combustion-supporting gas, combustible liquid mixture's injection scope, improved the atomizing angle.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art can easily modify, change or modify the above embodiments according to the technical spirit of the present invention without departing from the scope of the present invention.
