The specific implementation mode is as follows:

the following detailed description of the embodiments of the utility model is made with reference to the accompanying drawings:

the aerator comprises at least one aeration pipe 1 which is horizontally arranged below the liquid level, a plurality of aeration holes 10 are arranged on the pipe wall of the aeration pipe, and baffles 3 are respectively vertically arranged on the two sides of the pipe; when a plurality of aeration pipes are arranged, the first type is arranged in parallel along the horizontal direction, a main air inlet pipe is branched to be connected with air supply, and a baffle is arranged between every two aeration pipes; the second plurality of aeration pipes share a pair of baffles; and in the third mode, two baffles are arranged between two aeration pipes to form a return channel 6.

As shown in fig. 3, the baffle can be arranged in various ways:

one is that two sides of each aeration pipe are respectively provided with a baffle, referring to the first aeration pipe on the left side of the attached figure 3;

one is that a plurality of aeration pipes share a pair of baffles, see three aeration pipes on the right side of the attached figure 3;

one is that a baffle is arranged between two aeration pipes, which are shown in the left 2 and the left 3 of the attached figure 3;

in another type, two baffles are arranged between two aeration pipes, which are shown in the left 1 and the left 2 of the attached figure 3.

The part of the upper end of the baffle plate higher than the liquid level can restrain the air bubbles from being tightly converged among the baffle plates and colliding with each other to form an air bubble hedging dense area and increase the dissolution of oxygen (see figure 6), and in general, the air bubbles and the front baffle plate and the rear baffle plate form a closed box body 30 (see figure 5) or a gas stripping channel or a backflow channel (see figure 6); the special case is: when the embodiment is applied to engineering production lines such as an oxidation ditch for sewage treatment and the like, the aeration pipe and the baffle plate are arranged along the direction of water flow, and a front baffle plate and a rear baffle plate are not suitable to be arranged so as not to increase the overflowing resistance.

Bubbles emitted by a plurality of aeration holes or aeration heads on each aeration pipe form a plurality of strands of upward gas-liquid flows along a gas stripping channel formed by the baffle plate, and a hedging dense area 2 is formed at the liquid level; when a plurality of aeration pipes are adjacently arranged, the liquid level can form a hedging dense area similar to a grid array, so that the impact breakage of bubbles is intensified, and the dissolved oxygen efficiency is improved.

When a plurality of aeration pipes are arranged in parallel along the horizontal direction, a main gas pipe 5 can be branched to be connected with gas supply (see the attached figure 5), the other ends of the aeration pipes can also be mutually communicated to balance the pressure among the pipes (see the attached figures 1 and 2), and a section of downward tail pipe (see the dotted line part in the attached figure 1) can also be arranged in the horizontal pipeline system.

Further, as shown in fig. 4, the embodiment of the multi-layer aeration pipe is as follows: the multi-stage system is formed by overlapping more than two layers of aeration pipes 1, a gas collecting hood 31 is arranged between the multiple layers of aeration pipes, the gas collecting hood has the function of completely collecting undissolved gas of a lower-layer device, and then the gas is led out from an interstage gas conveying pipe 50 to be directly used as a gas source of a later-stage device, and the later-stage device is arranged right above the former-stage device or arranged beside the former-stage device in a staggered mode.

The gas pipe 5 supplies gas to the aeration pipe at the bottommost layer, undissolved gas is completely collected by the gas collecting hood 31, the liquid level in the gas pipe is gradually pressed down, when the liquid level is lower than any part of the pipe orifice of the interstage gas pipe 50, the gas starts to enter the gas pipe, when the pipe orifice is horizontally arranged downwards, a stable internal working liquid level 00 is formed near the position slightly lower than the pipe orifice, and bubbles are converged into the hedging dense area 2 and are continuously collided and dissolved; then undissolved gas enters a gas transmission main pipe at the next stage through an interstage gas transmission pipe 50 to be used as a gas source; by analogy, the layers can be stacked step by step; the working level of the uppermost layer may be set at ambient level 0.

The last level of multilayer combination, the working liquid level of the top layer can be established at the environment liquid level 0, so that after the multi-level device is dissolved layer by layer, the dissolving efficiency of oxygen is improved, the utilization rate of gas energy is also improved, and the occupation of the liquid level is reduced by times.

The components of the multilayer device can be fixed or float through a bracket floating body and the like, and the details are not repeated.

As shown in attached figures 5 and 6, the plate-frame type aerator comprises the following embodiments: two baffles 3 are arranged between two aeration pipes 1 to form a return channel 6, a bottom plate 33 is arranged below the aeration pipes to form a U-shaped groove together with the baffles on the two sides, front and rear baffles are arranged in the front and rear of the device to form a box body 30, the upper edge of the box body is higher than the environmental liquid level 0 and is also higher than the baffles 3 in the box body, and the front and rear baffles are provided with holes at the U-shaped groove part to be communicated with the surrounding liquid.

The return channel extends downwards to a designated depth in the liquid through the continuous telescopic extension pipe 60, so that the liquid with a large amount of gas fully dissolved in the top layer can be conveyed to the lower layer depth, the replacement and circulation of the upper liquid layer and the lower liquid layer are facilitated, and the overall dissolving efficiency is improved.

The aeration pipe aerates in the U-shaped groove to form an air-lifting effect, the gas-liquid flow gushes out from the upper end of the U-shaped groove to form a bulge higher than the liquid level 0, the bulge is limited by the upper edge of the box body and cannot flow out, and the gas-liquid flow can only flow into a return channel 6 beside the box body, and the gas-liquid flow 4 is collided to form a collision dense area 2 (see the attached figure 6); liquid is supplemented from the front baffle plate and the rear baffle plate at the opening of the U-shaped groove part; the extension pipe 60 can be extended to a designated depth in the liquid where the pressure inside and outside the pipe is balanced and there is no pressure at the bottom of the pipe at any depth when the liquid above the liquid level flows in at the top, so the upper layer of gas-rich liquid can be smoothly injected into the liquid environment at the designated depth, suitable for the integral equilibrium dissolution of a deeper and larger liquid pool
