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
