Description
Technical field
The utility model specifically a kind of two-stage is bled mixing jet aerator, belongs to water pollutions processing technology field.
Background technology
Underground water as the important component part of human living space, for the mankind provide the Freshwater resources of high-quality.But along with being on the rise of China's environmental pollution, mankind's activity causes underground pollution to expand to planar from point-like.Underground water, except self is contaminated, becomes again the important medium of soil pollution.Current Organic Contamination of Groundwater has become study hotspot both domestic and external.Ejector is widely used in water treatment field, existing ejector is primarily of nozzle, suction chamber, diffuser pipe three part composition, it is a kind of multi-usage aeration mode utilizing jet flow negative pressure principle to grow up, volatile contaminant in underground water such as tetracol phenixin can be evaporate in air, thus it is separated from water.But the ejector of this structure is merely able to carry out an air-breathing mixing, current and air can not be made fully to merge, and the bubble produced is fine and smooth not, can not volatile constituent in water be evaporate in air well.
Summary of the invention
For above-mentioned background technology Problems existing, the utility model provides a kind of two-stage to bleed mixing jet aerator, and after current and air can be made fully to mix, the bubble of formation is less, makes the water containing a large amount of volatile organic contaminant more volatile in air.
To achieve these goals, a kind of two-stage of the utility model is bled mixing jet aerator, comprise water-in, mixed flow nozzle and water outlet, described mixed flow nozzle inside is provided with injection trunnion, the two is fit with one heart, the afterbody of described injection trunnion is fixedly mounted on the afterbody of mixed flow nozzle, described mixed flow nozzle is made up of mixing section and supercharging storehouse, described mixing section is communicated with supercharging storehouse, the diameter in described supercharging storehouse reduces from tail end gradually to front end, described water-in is communicated with the mixing section of mixed flow nozzle by spraying trunnion, described mixing section top offers inlet mouth, described mixed flow nozzle front end is provided with the injection storehouse be connected with supercharging storehouse, front end, described injection storehouse is communicated with water outlet, described injection trunnion is bullet shaped, the diameter in described injection storehouse increases from tail end gradually to front end, filter screen is respectively equipped with in described injection storehouse and supercharging storehouse.
Preferably, the grid order number of filter screen is 16 ~ 20 orders.
Further, inlet mouth is located at above the water jet of injection trunnion.
Preferably, mixed flow nozzle is that liquid mixing stirs nozzle.
Compared with prior art, injection trunnion of the present utility model is bullet shaped, and current are when spraying injection trunnion, and the jet power produced is larger, the dispersion more of water flow jet, thus merges more abundant with air in mixing section.In addition, injection storehouse of the present utility model diameter increases from tail end gradually to front end, make the direction of dispersion of flow wider, the advantageously volatilization of pollutant component in water, spray in storehouse and be also provided with filter screen, the effect that there is cutting and filter, when being formed after steam-water mixing vacuole rolls into a ball after current and air mixed, this vacuole group is when flowing to water outlet, Linear cut is carried out through the filter screen sprayed in storehouse, thus cut and be divided into numerous little vacuole, advantageously in volatile organic matter as tetracol phenixin evaporate in air from water.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of two-stage is bled mixing jet aerator, comprise water-in 1, mixed flow nozzle and water outlet 8, described mixed flow nozzle inside is provided with sprays trunnion 2, the two is fit with one heart, the tail end (in Fig. 1, " left side " is tail end) of described injection trunnion 2 is fixedly mounted on the tail end of mixed flow nozzle, described mixed flow nozzle is made up of mixing section 4 and supercharging storehouse 5, described mixing section 4 is communicated with supercharging storehouse 5, described water-in 1 is communicated with the mixing section 4 of mixed flow nozzle by spraying trunnion 2, the diameter in described supercharging storehouse 5 reduces from tail end gradually to front end (Fig. 1, " right side " is front end), described mixing section 4 top offers inlet mouth 3, described mixed flow nozzle front end is provided with the injection storehouse 6 be connected with supercharging storehouse 5, front end, described injection storehouse 6 is communicated with water outlet 8, it is characterized in that, described injection trunnion 2 is bullet shaped, the diameter in described injection storehouse 6 increases from tail end gradually to front end, filter screen 7 is respectively equipped with in described injection storehouse 6 and supercharging storehouse, filter screen 7 can be larger in filtered water stream particle, make water quality better.
As preferred version of the present utility model, the grid order number of described filter screen 7 is 16 ~ 20 orders, and optimal selection is 18 orders, ensures, while filter screen 7 cuts bubble, to cause resistance to current, simultaneously can also particle further in filtered water.
As improvement of the present utility model, described inlet mouth 3 is located at above the water jet of injection trunnion 2.
