Description

Aeration structure on a membrane support

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to an aeration structure on a membrane support.

Background Art

In the submerged membrane sewage treatment system, perforated tubes are mostly used to provide disturbance and aeration and oxygenation for sewage. The bottom of the membrane module used in the traditional MBR membrane bioreactor is generally aerated with perforated tubes. Most of the gas is used for mud and water mixing, and a small part is used to increase the dissolved oxygen in the water. Since the flocs in the activated sludge are small and easy to break up during stirring, the density is light, and the sludge concentration is below 20,000 mg/L, and the appropriate concentration is about 8,000 mg/L. If it exceeds 30,000 mg/L, the sludge is thick and has no sedimentation concentration, which is difficult to improve in the submerged membrane treatment system. Therefore, the existing membrane module design aeration method is suitable for the biochemical method, and the gas volume is based on a gas-water ratio of 12:1, and the hydraulic retention time is about 6 hours.

For example, the patent publication number CN201521006342.0 discloses an aeration device for a high-concentration suspended solids submerged membrane module, which has a simple structure, is easy to manufacture, has a low manufacturing cost, and can be applied to a hollow fiber membrane separation water system with high-concentration suspended solids. However, this technical solution still has shortcomings, as follows:

This solution has multiple air outlets inside, but during use, sludge may accumulate above the air outlets, and the air outlets are easily contaminated and blocked by sludge for a long time, thus affecting the aeration work. Secondly, the bubble range of the air outlet is only directly above it, and the aeration range is limited. To this end, we propose an aeration structure on a membrane support to solve the above-mentioned problems.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with Figures 1-6.

Embodiment 1, referring to FIGS. 1-4 , in order to solve the problem of limited aeration range of the existing air outlet 202 , the utility model discloses an aeration structure on a membrane support.

include,

The membrane support assembly 100 further includes a stainless steel support 101, with aeration pipes 102 connected to both sides of the stainless steel support 101, two water production pipes 103 connected to the center of the stainless steel support 101, and two membrane stacks 104 connected to the inner side of the stainless steel support 101;

The dispersion component 200 also includes a bronchial tube 201, which is located on the inner side of the aeration tube 102. An air outlet 202 is connected to the top of the bronchial tube 201. The bronchial tube 201 cooperates with the air outlet 202 to aerate different areas. A first baffle 203 is arranged above the air outlet 202. Connecting rods 204 are connected to both sides of the first baffle 203. The bubbles are preliminarily dispersed by the first baffle 203 to increase the aeration range. A second baffle 205 is arranged above the first baffle 203. A center block 206 is arranged above the second baffle 205. A fixed block 207 is arranged above the center block 206. The second baffle 205 cooperates with the center block 206 to perform secondary aeration dispersion to increase the aeration range.

The specific working principle is: first, the stainless steel bracket 101 is placed in the treatment pool that needs to be treated with sewage, and then the aeration pipe 102 is connected so that air begins to enter from the inside of the bronchus 201. The air flows out through the air outlet 202 and contacts the water flow to form bubbles. The bubbles in the central area flow directly upward, while the bubbles at the edge hit the top of the first baffle 203 and flow toward both sides along the first baffle 203. After that, a part of the center hits the top of the second baffle 205 and continues to be diverted. Finally, the bubbles flow upward along the first baffle 203, the second baffle 205 and the center block 206 respectively, and are divided into six streams, thereby greatly increasing the aeration range.

Embodiment 2, referring to FIGS. 2-3 , in order to solve the problem that the existing gas outlet 202 is easily blocked due to long-term immersion in sludge, based on the same concept as the above-mentioned embodiment 1, the aeration structure on the membrane support further includes:

The anti-blocking component 300 also includes a filter screen 301, which is located inside the stainless steel bracket 101. The filter screen 301 blocks sludge to prevent it from contacting the air outlet 202. A vibration spring 303 is connected to the top of the filter screen 301, and a vibration plate 302 is connected to the top of the vibration spring 303. The vibration plate 302 cooperates with the vibration spring 303 to prevent sludge from accumulating on the top of the filter screen 301 and causing blockage. Rotating rods 304 are connected to both sides of the filter screen 301, and a closing block 305 is connected to the outer side of the rotating rod 304. A temporary storage box 306 is connected to the bottom of the closing block 305. The sludge is sealed by the closing block 305 to prevent the sludge from flowing back to the top.

The filter screen 301 is installed in an integrated manner with the stainless steel bracket 101. The filter screen 301 has a conical structure. The filter screen 301 forms a rotating structure with the closing block 305 through the rotating rod 304. Torsion springs are provided on both sides of the rotating rod 304. The filter screen 301 cooperates with the stainless steel bracket 101 to filter the sludge to prevent the sludge from directly contacting the air outlet 202.

The filter 301 forms a spring vibration structure through the vibration spring 303 and the vibration plate 302. The vibration plates 302 are evenly and equidistantly distributed on both sides of the filter 301. The width of the vibration plate 302 is consistent with the width of the filter 301. The vibration plate 302 cooperates with the vibration spring 303 to shake the sludge to prevent the sludge from accumulating on the top of the filter 301.

The specific working principle is as follows: as mentioned above, during the aeration process, the filter screen 301 covers the air outlet 202 to prevent it from directly contacting the sludge. When sludge enters the interior of the stainless steel bracket 101, it first contacts the filter screen 301, and the filter screen 301 itself is a conical structure. The sludge then moves toward both sides along the filter screen 301 and accumulates above the closing block 305. When some sludge is more stubborn, the bubbles rise to lift up the vibration plate 302, and the vibration spring 303 under the vibration plate 302 pulls it to reset, so that the vibration plate 302 is continuously raised and lowered, so that the sludge and the filter screen 301 are dispersed during the vibration process until all fall above the closing block 305. When too much sludge accumulates, the closing block 305 rotates downward, so that all the sludge falls into the temporary storage box 306, and the torsion springs on both sides of the rear rotating rod 304 drive the closing block 305 to reset and seal the sludge.

Embodiment 3, referring to FIGS. 5-6 , in order to solve the problem of fixed aeration range in the prior art, based on the same concept as the above-mentioned embodiment 1, the aeration structure on the membrane support further includes:

The auxiliary component 400 also includes an auxiliary block 401, which is located on both sides of the bronchus 201. A connecting block 402 is connected to the top of the auxiliary block 401. The auxiliary block 401 cooperates with the connecting block 402 to limit the sliding block 404, so as to carry out subsequent work. The inner side of the connecting block 402 is connected to the sliding block 404, the center of the sliding block 404 is connected to the rotating block 403, and the top of the rotating block 403 is connected to the spiral block 405. The spiral block 405 is rotated by the collision of bubbles, thereby driving the rotating block 403 to rotate, driving the bubbles to the surroundings, and increasing the aeration range.

The auxiliary block 401 is installed in an integrated manner with the stainless steel bracket 101. The auxiliary blocks 401 are symmetrically distributed on both sides of the air outlet 202. The connection method between the auxiliary block 401 and the connecting block 402 is a hot-melt connection. The connection method between the connecting block 402 and the sliding block 404 is a sliding connection. The auxiliary block 401 cooperates with the stainless steel bracket 101 to limit the connecting block 402, thereby limiting the rotating block 403 to ensure subsequent work.

The sliding block 404 rotates integrally with the rotating block 403. The rotating block 403 is in a circular shape. The spiral blocks 405 are evenly and equidistantly distributed on both sides of the rotating block 403. The spiral blocks 405 rotate by the circulation of bubbles, thereby driving the rotating block 403 to rotate, so that the bubbles move toward the surroundings to increase the aeration range.

The specific working principle is as follows: as described above, when the bubbles move upward, they hit the top of the spiral block 405, thereby driving the spiral block 405 to rotate. When the spiral block 405 rotates, it drives the rotating block 403 to rotate. The rotating block 403 rotates through the sliding block 404. During the rotation, the spiral block 405 continuously drives the bubbles to the surroundings to form a circular aeration range. At the same time, a part of the bubbles rise directly from the center direction of the rotating block 403 to prevent the formation of dead corners.

The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
