Releaser 5 (jet) structure

The releaser 5 mainly functions to release the mixed dissolved air water in a high-pressure supersaturated state and ensure that the mixed dissolved air water has a jet effect when being released into river water.

Specifically, as shown in fig. 2 and 3, the releaser 5 includes a nozzle 51, a pressure reducing disk 52, and a communicating ring 53, and the pressure reducing disk 52 may be made of stainless steel 304 or the like. The communication ring 53 is screwed loose from the nozzle 51 by the thread of the inner wall, thereby adjusting the relative position. Between the nozzle 51 and the communicating ring 53, there is a decompression disc 52 with a decompression hole in the shape of an inverted cone, and the decompression disc 52 is fixed with the nozzle 51 by the screw thread of the inner wall.

More specifically, as shown in fig. 5, at least one pressure reducing hole is provided on the annular edge of the pressure reducing plate 52 for allowing the mixed dissolved air water to pass through, and the number of the pressure reducing holes can be flexibly set as required, preferably 3 pressure reducing holes.

The water inlet pipe 1 is communicated with the communicating ring 53, and parameters can be adjusted according to actual requirements to obtain appropriate (angle, aperture and the like) jet effect. During adjustment, the communicating ring 53 can be unscrewed, the pressure reducing disc 52 can be directly adjusted through the water outlet of the nozzle 51 by using a square wrench, the communicating ring 53 can be screwed after adjustment is completed, and the operation is simple and does not need to be disassembled.

Further, the pressure reducing disk 52 can be screwed up and down by a square wrench through a straight hole in the middle of the nozzle 51.

further, as shown in fig. 2 to 4, there is a gap between the nozzle 51 and the pressure reducing disk 52, and the size of the gap space is flexibly adjusted according to the size of the angle α and the angle β in fig. 2, so that the degree of squeezing the mixed liquid flowing out from the pressure reducing hole is controlled to allow the mixed liquid to remain a large pressure and to be flushed out.

more specifically, after the mixed dissolved air water is delivered to the communicating ring 53, the mixed dissolved air water is first discharged to the gap between the nozzle 51 and the pressure reducing disk 52 through the pressure reducing holes of the pressure reducing disk 52, and is pressed, the degree of pressing is affected by the size of the gap and the angle α β, and then the mixed dissolved air water is rapidly discharged into the river through the small holes of the nozzle 51 in a high pressure supersaturated state, and for example, the angle α between the inner side of the nozzle 51 and the axis is set to α, the angle β between the inverted conical surface of the pressure reducing disk 52 and the axis is set to 30 to 60, the angle adjustment range of α is preferably 25 to 70, the width range of the gap between the nozzle 51 and the pressure reducing disk 52 is preferably 1 to 8mm, and, when 3 pressure reducing holes are provided on the pressure reducing disk 52, as shown in fig. 5, w represents the "pressing" diameter "of the pressure reducing disk 52, that is, that the projection distance from the inner edge of one pressure reducing hole along the center to the inner edge of the symmetrical pressure reducing holes is smaller, that is also referred to the relative distance of the inner edge of the pressure reducing hole, D3 represents the larger, that is, the mixed liquid is allowed to pass through.

It should be noted that, compared with the conventional method, the high-pressure gas-dissolving water in the conventional method is extruded and released through the gap spaces for many times, and is finally released into the polluted river channel at normal pressure. And according to the utility model discloses, mix the dissolved air water and still keep high pressure supersaturation state efflux to the river course the inside as far as possible after the secondary extrusion. Specifically, the steam-containing water is subjected to primary extrusion when flowing through the pressure reducing hole, and is subjected to secondary extrusion when passing through the gap between the nozzle 51 and the pressure reducing disk 52. Through the secondary extrusion, the high-pressure supersaturated state can be kept as much as possible, and the jet flow is jetted into a river channel.

Further, conventionally, the release device 5 is used to rapidly decompress to generate "micro bubbles", and then the oxygenation is achieved by means of gas-liquid exchange, in the process, the pressure of the dissolved gas water is basically released inside the release device 5, the flow rate of the liquid is reduced to be very low, and the oxygenation efficiency is affected because the gas in the dissolved gas water is basically formed into bubbles and continuously enriched and formed into large bubbles to be dissipated into the air in the subsequent transmission process. Comparatively speaking, the utility model discloses a through 5 high pressure jets out supersaturation mixed dissolved air water of releaser, the in-process is because obvious gradient difference (take the air as the example and mix dissolved oxygen DO concentration in the dissolved air water and can reach 30mg/L theoretically when the DO of water is 0mg/L, the DO of polluting the river course water is generally at 0 ~ 2mg/L) and the turbulent effect that the high-speed ejection produced, just realize oxygenating fast through liquid-liquid exchange mode with polluting the river course water when mixing dissolved air water and basically not reaching and producing a large amount of microbubbles, consequently, it is better to dash the oxygen effect. In the traditional mode, air is taken as an example, when DO of the incoming water is 0mg/L, the DO of the water outlet of the releaser is generally 6-8 mg/L which is greatly different from a theoretical value;

further, the structure of the releaser 5 of the present invention can be adjusted by design to form a similar "micro bubble" release as the conventional one, but obtain a better micro bubble effect. That is, compare the low transmission process of the ordinary pressure velocity of flow of traditional mode and enrich front end release characteristics such as loss easily, the utility model discloses thereby can release more dissolved gas and produce more better microbubble effects when terminal obviously. In addition, experimental data can be further seen below.

In addition, compare with the conventional mode, the utility model discloses 5 structures of releaser are simpler, and adjust the convenient maintenance that realizes more easily.

meanwhile, the utility model discloses a structural design and adjustable realization, on the one hand keep fine oxygenating effect, and on the other hand is, compare with the mode that direct through-hole efflux was gone out, the utility model discloses can be according to the improvement area demand of river course improvement scheme and the effect demand of oxygenating, alpha, β angle, H isoparametric of releaser 5 are calculated in the design, the design size of nozzle 51 aperture D1D 2 is being cooperated, adjusts the actual fluidic flow and speed in a flexible way, realizes oxygenating the balanced management and control of area and flow, ensures to realize the effect that many 5 distributing type of releaser of group arrange.

Because, as described above, most of the dissolved oxygen instantaneously diffuses out of the surrounding fluid in time with liquid-liquid exchange before escaping; moreover, the liquid performance updating probability is obviously increased through the strong radial shearing force generated during quick ejection and the stirring action of severe turbulent flow; further, as the jet is formed, the aeration affected area increases. Under the condition, the dissolving speed of oxygen can be effectively controlled, a better effect is achieved, and the phenomena of oxygen enrichment and the like can be effectively avoided, so that the treatment effect of river pollution is effectively improved.

Also, the microbial agents may be distributed uniformly and widely throughout the river as the water flows through the releaser 5, for example: river bottom, river course, surface, corner, etc. and the area of pollution control is larger, and the area of influence of microbial inoculum placement can perfectly coincide with the area of aeration and oxygen flushing. According to the experimental measurement and calculation, through the adjustment and control of the integrated aerator, the project can realize the perfect matching degree between the bacterial adding amount and the oxygen adding amount and the influence area, ensure that the microbial flora can be in the best degradation activity after being released, and play the best aeration pollution control effect. Therefore, the treatment effect of river pollution is further improved.

In addition, the number, the jet flow direction and the distribution of the aeration releasers 5 and the putting amount of microorganisms are flexibly adjusted according to specific environment and water quality conditions, in other words, according to actual conditions and a test model, the method calculates and more pertinently puts in the sewage treatment, can more effectively keep the microbial biomass and the activity which are adaptive to the actual pollution concentration of the black and odorous riverway, realizes accurate control and accurate putting, obviously reduces the using amount of the microbial agent, further improves the treatment effect of the riverway pollution, is simpler to operate, and obviously reduces the cost.

To sum up, the utility model discloses not only can improve the treatment effect of river pollution to the installation is simple and easy, low in manufacturing cost, and effective festival reduces the microbial inoculum quantity.

and (3) analyzing an experimental result:

1) the biggest difference between the mode 1 and the mode 2 is that the latter is front end release, and the former is designed and adjusted to be end release, and the comparison of the two data means that the end release mode can pull the position of the releaser farther to obtain the same effect, but actually, no substantial DO effect breakthrough is obtained, which means that the conventional method for considering the oxygenation effect of the river aeration by the air flotation principle is limited to a certain extent;

2) in the mode 3, the jet flow and the tail end release can obviously obtain the effect of realizing rapid oxygen transfer at different positions along the jet flow direction, and the increase of the time DO before and after shows that the oxygen utilization rate of the mode is high, so that a larger oxygen influence area is obtained on the whole, the oxygenation effect is more ideal, and the mode 3 is substantially more advanced than the modes 1 and 2;

3) in the test process, the high-concentration mixed gas-dissolved water in the mode 1 and 2 is dispersedly released, and larger bubbles can be often seen to float upwards and release from the water bottom; the reason is that the oxygen concentration at the water outlet is high, the influence area is small, dissolved oxygen cannot be rapidly diffused out due to the concentration difference, but large bubbles are continuously formed to escape due to the excessive enrichment caused by the influence of the actual environment such as slow flow rate of a black and odorous river channel, and the experiment is mutually verified with the deduction of the test data, so that the aeration of the river channel is designed in the existing air floatation mode, and the oxygenation effect is not ideal; in contrast to the method 3, the high-concentration mixed dissolved air water is released in a jet flow manner, so that most of the dissolved oxygen is instantly diffused out along the jet flow direction through liquid-liquid exchange with surrounding fluid before escaping; on the other hand, strong radial shear force and violent turbulent stirring action are generated during jet flow, and the dissolution and diffusion speed of oxygen is faster, which is adapted to the growth rule of DO in the data; along with the injection stroke, the aeration influence area is large, and the phenomena of oxygen enrichment and the like cannot occur;

by the above, we can see that, compare the aeration mode of air supporting principle, the utility model discloses with the mode of efflux + terminal mode design, oxygen solubility, oxygen utilization ratio will improve greatly, and area of influence and effect are also showing more moreover.
