Multifunctional combined atomizing lance

Abstract

The invention relates to a multifunctional combined atomizing lance, mainly comprising a combined atomizing spraying head, a compression nut, a multilayer flow divider, an outer lance tube, a medium conduct, an inner lance tube, a center lance tube, a combined lance seat and a pipe joint. The multifunctional combined atomizing lance can simultaneously atomize liquid fuel with different physical properties and independently combust or combust the liquid fuel in a mixed mode by adopting different atomizing modes. The combined atomizing spraying head is not only provided with a mechanical atomizing swirl slot and a swirl chamber, but also provided with a medium atomized oil hole, vapor hole and mixed hole structure. Various fluids enter the multilayer flow divider though self pipeline first and then enter the combined atomizing spraying head for atomizing. Fuel with lower viscosity is strongly rotated, atomized and sprayed by a center spray hole, contacted with the outside atmosphere and broken into fine oil drop to form oil mist, fuel oil with higher viscosity enters the combined atomizing spraying head, is sheared by vapor and rotated at high speed; and oil flow is impacted to generate a fluid film at an oil gun output and broken by the action of surface tension, thereby forming small granules. The multifunctional combined atomizing lance has high atomizing quality.

Description

technical field [0001] The invention relates to an atomizing spray gun, in particular to a multifunctional combined atomizing spray gun capable of simultaneously or separately atomizing different liquid fuels. Background technique [0002] The atomizing spray gun is the core equipment of the boiler burner. Before the liquid fuel is burned, it usually needs to be atomized into fine particles by the atomizer. The liquid particles are surrounded by air, and when they reach a certain temperature, they will react violently and form combustion. Therefore, the quality of the atomization is very important. The combustion process of the fuel has a greater influence. [0003] At present, the atomization spray guns commonly used on various oil burners mainly have two types of atomization, namely, mechanical atomization (including centrifugal type and rotary cup type) and medium atomization. The medium atomization is mainly used for fuels with low viscosity such as light diesel oil, an...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two main types of atomization spray guns commonly used on various oil burners, namely mechanical atomization (including centrifugal type and rotary cup type) ) and medium atomization, the mechanical atomization of the mechanical atomization spray gun is mainly used for fuels with low viscosity such as light diesel oil, and the medium atomization is mainly used for heavy oil, residual oil and other fuels with high viscosity and large spray gun output. The fuel with physical properties needs to use spray guns with different atomization forms, and for burners that need to burn different fuels, the spray guns must be replaced artificially, and the time interval for replacing the spray guns will cause the burner to be out of service, which will bring problems to the operation. inconvenient
