Abstract
The utility model discloses a kind of novel airless injection apparatus, comprise the upper outlet body that steam inlet is arranged on top, connecting plate, upper mounted plate, bottom plate and lower cover, three nozzles are installed between connecting plate and upper mounted plate, side is provided with intakeport, upper mounted plate and bottom plate are provided with three diffusing tubes, of the present utility modelly to be a little: improved novel evacuated sparger, work jet is thinner, air-water two phase flow has good mass transfer effect, interference is not produced between multiple jets, water jet kinetic energy rejection is little, increase mass transfer area, manufacture vacuum capacity is large.In oils industry, the novel vacuum system be made up of multiinjector many expanders sparger and condenser compared with traditional level Four or Pyatyi vapor pump, stable performance, reliability is strong, and steam and water consumption reduce, and noise is low, and waste water production is little; Working steam pressure requires low, and Security improves, and safety class requires to reduce.
Description
Technical field
The utility model relates to novel evacuated injector device in a kind of vacuum system be used in grain and oil manufacture.
Background technique
Steam jet ejector is connected with the system of being evacuated, and in steam jet ejector, working steam is expanded under vacuum conditions by Laval nozzle, and potential energy is kinetic energy, forms the cold steam jet of supersonic speed at nozzle exit.Due to the Involving velocity of cold steam jet, working steam carries out momentum and mass exchange with pumped gas, mutually mixes.Mixed gas, through supersonic diffuser, forms shock wave at the venturi of Diffuser or the outlet port of extending section.Due to the pressurization of shock wave, make the pressure of pumped gas and working steam mixed flow be elevated to the back pressure value of design, and flow into condenser.Traditional emitter construction is single nozzle list expander, and when rate of air sucked in required is larger, water spray bore needs very large, and water jet is thick, and cause air water mass transfer insufficient, water jet kinetic energy can not be fully used.For solving this difficult problem, devise a kind of novel vacuum ejector.
Summary of the invention
The purpose of this utility model be to provide a kind of air water mass transfer fully, water-jet flows the airless injection apparatus of being fully used novel.
The purpose of this utility model is achieved through the following technical solutions: this novel airless injection apparatus comprises steam inlet and is arranged on the upper outlet body at top, connecting plate, upper mounted plate, bottom plate and lower cover, be provided with between connecting plate and upper mounted plate three nozzles (, side is provided with intakeport, and upper mounted plate and bottom plate are provided with three diffusing tubes.
Of the present utility modelly to be a little: improved novel evacuated sparger, work jet is comparatively thin, and air-water two phase flow has good mass transfer effect, does not produce interference between multiple jets, and water jet kinetic energy rejection is little, increases mass transfer area, manufactures vacuum capacity large.In oils industry, the novel vacuum system be made up of multiinjector many expanders sparger and condenser compared with traditional level Four or Pyatyi vapor pump, stable performance, reliability is strong, and steam and water consumption reduce, and noise is low, and waste water production is little; Working steam pressure requires low, and Security improves, and safety class requires to reduce.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1, upper outlet body 2, connecting plate 3, nozzle 4, upper mounted plate 5, diffusing tube 6, fixed plate 7, lower cover 8, intakeport.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail.
On figure, this kind of novel airless injection apparatus comprises steam inlet and is arranged on the upper outlet body 1 at top, connecting plate 2, upper mounted plate 4, bottom plate 6 and lower cover 7, three nozzles 3 are installed between connecting plate 2 and upper mounted plate 4, side is provided with intakeport 8, and upper mounted plate 4 and bottom plate 6 are provided with three diffusing tubes 5.
