Description
Technical field
The utility model belongs to the environmental protection equipment technical field, is specifically related to a kind of novel jet flow aerating apparatus, relates in particular to a kind of high-efficiency jet flow aeration device that is applicable to rectangular wastewater tank.
Background technology
Aeration is to utilize aerobic biodegradable principle to carry out a biochemical treatment process of sewage disposal, and traditional aerator designs aerator according to two film (moisture film, air film) theories, as mechanical blast aeration, impeller aerator, aeration oxygen replenishing pump etc.Jet-flow aeration is to utilize principle of water-jet to carry out gas, water mixing, to reach the aeration purpose.The tradition efflux aerator adopts the butterfly structure, uniform all around circular distribution, for general big sink drainage, this type of efflux aerator commonly used, but for the aerator and rectangle sewage reaction tank of arranged, its stirring, aeration act on each crossing interface and the aeration central point is unbalanced.Equally, also exist imbalance in the different depth of water degree of depth, this can bring influence to the aeration effect.
Summary of the invention
For overcoming above-mentioned defective, the purpose of this utility model provides a kind of novel rectangle aerobic reaction pond that is applicable to and uses the jet-flow aeration equipment of efficient, high oxygen transfer efficiency and dynamic efficiency.
The defective that the utility model exists at prior art according to air film, liquid film common phase film transition principle altogether, can produce micro-bubble, according on the large-scale simulator experiment basis and a kind of novel rectangular efflux aerator of design improvement.
The technical scheme that realizes the utility model purpose is such: high-efficiency jet flow aeration device is a circular configuration, the middle part is provided with water inlet and reaches air intake structure down, the bottom is provided with some supports in order to install and fix at the bottom of pond, aerobic reaction pond, be distributed with 3～12 jet aerators that communicate with last water inlet and following air intake structure in the circular configuration, the distribution angle of jet aerator is determined according to aerobic reaction pond long-width ratio; Each jet aerator is provided with two nozzles, the air water mixing nozzle of promptly inotropic water jet nozzle and dispersion pattern.
Usually, the utility model to the ejector air feed, forms air water turbulent flow mixing section by gas blower between two nozzles, and air and water thorough mixing have improved oxygen transfer efficiency effectively.
Advantage of the present utility model is: aerating apparatus can make the stirring of rectangle aerobic reaction pond, oxygenation even relatively, effective, effective simultaneously raising air utilization ratio, dynamic efficiency and mixing efficiency, reduction gas blower power consumption, the installed capacity of minimizing gas blower, reduction running cost.
The utility model device possesses favorable applicability, is applicable to the use of all kinds of sewage aerobic reaction tanks of large, medium and small type.
Description of drawings
Accompanying drawing 1 is the two dimensional structure synoptic diagram of present embodiment efflux aerator; Accompanying drawing 2 is A-A ' cross-sectional view of Fig. 1.
In the accompanying drawing, the 1-water-in; The 2-air inlet port; The 3-water jet nozzle; 4-air water mixing nozzle; The 5-lower cover; The 6-upper cover plate; The 7-support; 8-air water turbulent flow mixing section.
Embodiment
Below in conjunction with drawings and Examples the utility model further is illustrated.
Embodiment: shown in accompanying drawing 1,2, present embodiment is a circular configuration, the device middle part is provided with water-in 1 and reaches air inlet port 2 down, the bottom is provided with some supports 7 in order to install and fix at the bottom of pond, aerobic reaction pond, be distributed with ten jet aerators that communicate with last water-in 1 and following inlet mouth 2 in the circular configuration, the distribution angle of jet aerator is determined according to aerobic reaction pond long-width ratio; Each jet aerator is provided with two nozzles, the air water mixing nozzle 4 of promptly inotropic water jet nozzle 3 and dispersion pattern; 8 is air water turbulent flow mixing section, current and air-flow from 1 and 2 in air water turbulent flow mixing section 8 form supercharging turbulent flow gas-water mixture, air water mixed solution bubble is dispersed into small mist, and passes through air water mixing nozzle 4, reached the requirement of aerobic reaction its high fast direction aerobic reaction pond; Present embodiment also comprises cover plate 6,5 up and down.
Because sewage plant (factory) needs because of limiting or design whole the arrangement, the aerobic reaction pond often is not regular square, rectangle or circle.Present embodiment is applied to the rectangle Aerobic Pond, and long 20 meters, wide 16 meters, the most reasonable approach is 6 jet-flow aeration equipment of cloth.But the area that each jet aerator equipment need be served in theory is 8 meters * 6.67 meters, and non-square or circle.Therefore for adapting to this variation, as shown in Figure 1, during the jet-flow aeration equipment design of present embodiment, the distribution of ten jet aerators is not uniform, count counterclockwise from A ' edge, its angle is respectively 35 °, 33.5 °, 43 °, 33.5 °, 35 ° (second half symmetries with it that distribute) between any two.A-A ' axle was with to grow the limit parallel when present embodiment was installed, and so just can revise the jet-flow aeration problem of uneven distribution that the reason that differs owing to the Aerobic Pond size causes substantially.
Present embodiment, the diameter of efflux aerator are 1.4 meters, water inlet pipe caliber ∮ 250mm, and the water jet caliber is ∮ 80mm, the minimum place of nozzle caliber is ∮ 40mm; Air water mixing nozzle caliber is ∮ 150mm, and funnel profile of jet hole band helps air water and disperses up and down.
The utility model apparatus structure is simple, promptly helps the simplification of manufacturing process, helps reducing the decay of water-jet energy and gas energy again.There is multiple medium (water, gas and pollutent) to exist in actual use in the sewage,, quickened the biochemical action of aerobic microbiological in the mud, improve wastewater treatment efficiency through the jet-flow aeration effect.
