Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and particularly relates to an electrolytic flotation device. Background Art

[0002] The electrolytic flotation device is a device that uses electrolytic flotation to treat wastewater. It is mainly used for the treatment of oily wastewater. The electrolytic device electrolyzes the wastewater under the action of a DC electric field to generate very small electrolytic bubbles that intercept flocs in the wastewater, reduce the specific gravity of the flocs, and cause them to float to form scum floating on the water surface. The scum is scraped away by a slag discharger and taken to a slag discharge tank for discharge.

[0003] However, in existing electrolytic flotation devices, the separation effect of scum and wastewater is not good. A large amount of flocculants tend to settle at the bottom of the wastewater after separation from the scum, and the subsequently discharged water contains a large amount of scum and flocculants. Summary of the Invention

[0004] The purpose of this application is to provide an electrolytic flotation device to solve the above-mentioned technical problems existing in the prior art.

[0005] This application is implemented as follows:

[0006] An embodiment of the present application provides an electrolytic flotation device, comprising a cell body, a first baffle, a second baffle, an electrolytic device and a scraper; the cell body is provided with a water inlet, a drain outlet and a slag trough; the first baffle is fixed in the cell body, dividing the interior of the cell body into a first area connected to the water inlet and a second area connected to the drain outlet, the first baffle has a water outlet connecting the first area and the second area, the width of the water outlet is less than half the width of the first baffle, and the slag trough is arranged in the second area and is located above the drain outlet; the second baffle is installed in the cell body, located above the second area, and one end of the second baffle is connected to the upper end of the first baffle, and the other end is located above the slag trough; the electrolytic device is installed in the first area, located below the water outlet; the scraper is installed in the cell body, and the scraper of the scraper is configured to move from the first area to the upper surface of the second baffle, and push the slag on the upper surface of the second baffle into the slag trough.

[0007] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0008] In the present application, a first partition is used to separate the interior of the tank body into a first area and a second area, the electrolysis device is installed in the first area, and the wastewater in the first area enters the second area through the water outlet on the first partition. Even if bubbles on the surface of the scum accidentally burst and cause the flocs to fall back into the wastewater in the first area, since the width of the water outlet is smaller than the width of the tank body, the size of the water outlet is smaller, which can extend the path of the flocs located on the side of the water outlet to flow to the water outlet to a certain extent, prolong the flow time of the flocs, thereby increasing the probability of the electrolytic bubbles re-intercepting the flocs, allowing the flocs to re-surface and be scraped away by the scraper, thereby reducing the number of flocs ultimately discharged from the drain.

[0009] In addition, a second partition connected to the first partition is provided above the second area. After the scraper of the scraper scrapes the scum to the surface of the second partition, the scum flows on the surface of the second partition, thereby preventing the scum from falling into the second area and reducing the number of flocs discharged from the drain.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0021] An embodiment of the present application provides an electrolytic flotation device, including a cell body 100 , a first baffle 300 , a second baffle 400 , an electrolysis device 500 , and a scraper 600 .

[0022] refer to Figure 1 and Figure 2 As shown, the tank body 100 is hollow and has a water inlet 110, a water outlet 120, and a slag trough 200. Wastewater is transported from the water inlet 110 to the tank body 100 for treatment, and the treated wastewater is discharged from the water outlet 120. The scum generated during the wastewater treatment process is stored in the slag trough 200 for centralized discharge.

[0023] refer to Figure 7As shown, the first baffle 300 is fixed within the tank body 100, dividing the interior of the tank body 100 into a first area 130 connected to the water inlet 110 and a second area 140 connected to the drain outlet 120. The first baffle 300 has a water inlet 310 connecting the first area 130 and the second area 140. The width of the water inlet 310 is less than half the width of the first baffle 300. The first baffle 300 blocks the first area 130 and the second area 140, making the two areas independent. Sewage enters the first area 130 from the water inlet 110, then passes through the water inlet 310 into the second area 140, and is finally discharged through the drain outlet 120. The slag chute 200 is located in the second area 140 and above the drain outlet 120.

[0024] The second baffle 400 is installed in the tank body 100 and is located above the second area 140. One end of the second baffle 400 is connected to the upper end of the first baffle 300, and the other end is located above the slag chute 200. Figure 5 and Figure 6 The electrolytic flotation device provided in the embodiment of the present application is placed on the ground for use. The upper end of the first baffle 300 refers to the upper, higher end, that is, the end of the first baffle 300 away from the bottom of the cell body 100.

[0025] refer to Figure 5 and Figure 6 As shown, electrolysis device 500 is installed in first area 130 and located below water outlet 310. Electrolysis device 500 is used to provide a DC electric field in the wastewater to electrolyze the wastewater and generate electrolytic bubbles. Water outlet 310 is located above electrolysis device 500 to prevent it from obstructing water outlet 310 and affecting the flow of wastewater between first area 130 and second area 140.

[0026] The scraper 600 is used to remove scum from the surface of the wastewater. The scraper 600 includes a scraper 610 that directly contacts and displaces the scum. The scraper 610 is configured to move from the first region 130 to the upper surface of the second separator 400 and push the scum from the upper surface of the second separator 400 into the scum discharge chute 200.

[0027] When using the electrolytic flotation device provided in the embodiment of the present application, it is necessary to pay attention to the water level of the wastewater in the first area 130, so that the scum on the surface of the wastewater is located at the corresponding height position of the scraper 610, to ensure that the scraper 610 can extend downward to the bottom of the scum and even continue to extend downward into the water body adjacent to the bottom of the scum to contact the scum. Therefore, in the process of the scraper 610 moving from the first area 130 to the second partition 400, the scraper 610 can push the scum on the surface of the wastewater in the first area 130 to move to the upper surface of the second partition 400. The scraper 610 continues to move on the upper surface of the second partition 400, pushing the scum to the end position of the second partition 400 away from the first area 130. This end of the second partition 400 is located above the slag discharge trough 200. After the scum falls from the end of the second partition 400, it falls directly into the slag discharge trough 200 below.

[0028] Since the second partition 400 is directly connected to the upper end of the first partition 300, after the scraper 610 pushes the scum on the surface of the wastewater in the first area 130 to the upper surface of the second partition 400, the scum continues to move on the upper surface of the second partition 400 until it falls into the scum discharge trough 200. The scum will not fall into the second area 140 below the second partition 400, thereby reducing the number of flocs in the second area 140 and reducing the number of flocs finally discharged from the drain outlet 120.

[0029] After the scum is pushed to the upper surface of the second partition 400 by the scraper 610, the second partition 400 can provide the scum with a forward path directly to the scum discharge trough 200, making the handling of the scum more convenient; and, even if part of the scum is out of the range of action of the scraper 610 on the second partition 400, under the pushing action of other scum, the detached scum can also be pushed by the subsequent scum to move toward the scum discharge trough 200. During the movement, the scum in front and the scum in the back will gradually accumulate and compact, squeezing out a certain amount of water.

[0030] Furthermore, the first partition 300 separates the first region 130 from the second region 140. The two regions are connected only by the water inlet 310. Wastewater or flocs in the first region 130 can only enter the second region 140 through the water inlet 310. Most of the flocs in the first region 130 float to the water surface under the action of the electrolytic bubbles generated by the electrolysis device 500, forming scum. This scum is then scraped to the upper surface of the second partition 400 by the scraper 610. However, because the scraper 610 is scraping away the scum, the water beneath it provides unstable support. The scraper 610 can easily disturb the scum, causing bubbles on the scum's surface to burst or merge, reducing the buoyancy of the flocs. This causes the flocs to fall back into the wastewater in the first region 130, where they then follow the flow of the wastewater toward the second region 140.

[0031] Because the water outlet 310 is relatively small, some flocs may come into contact with areas of the first separator 300 not provided with the water outlet 310 during their flow to the second region 140 before flowing toward the water outlet 310. This can, to a certain extent, prolong the flow path of the flocs, thereby increasing their flow time. During this period of floc flow, the electrolytic bubbles generated by the electrolysis device 500 are more likely to re-intercept the flocs, allowing the flocs to resurface and be carried away by the scraper 610. This reduces the amount of flocs that flow to the second region 140 and reduces the amount of flocs ultimately discharged from the drain outlet 120.

[0032] The longer the flocs remain in the first region 130, the greater the probability that they will be captured by the electrolytic bubbles and the greater the probability that they will float to the surface. The provision of the first baffle 300 and the smaller water outlet 310 provide an obstacle to the flow of the flocs, thereby extending the flocs' residence time in the first region 130 and increasing the probability that they will float to the surface again.

[0033] The slag chute 200 is fixed inside the pool body 100 , and the top of the slag chute 200 is open to receive slag dropped from the end of the second partition plate 400 above.

[0034] The scraper 600 is generally provided with a plurality of scrapers 610, which circulate and continuously scrape the scum on the surface of the wastewater in the first area 130 to the upper surface of the second partition 400. Figure 3 and Figure 4 As shown, the scraper 600 further includes a drive motor 620 and a transmission belt 630. The scraper 610 is mounted on the surface of the transmission belt 630. The drive motor 620 drives the transmission belt 630, thereby driving the scraper 610 to move in a circular motion. The movement path of the scraper 610 can cover the entire second partition 400 or only the front half of the second partition 400 near the first area 130. In both cases, the scum can be pushed into the slag discharge chute 200.

[0035] In some preferred embodiments of the present application, the second baffle 400 includes a horizontal section 410 and an inclined section 420 connected in sequence along the direction from the first region 130 to the second region 140. The end of the inclined section 420, remote from the horizontal section 410, extends toward the top of the tank body 100. The direction from the first region 130 to the second region 140 is the direction in which the scraper 610 scrapes the scum away from the second baffle 400. Due to the inclined configuration of the inclined section 420 of the second baffle 400, the end of the inclined section 420, remote from the horizontal section 410, gradually rises and eventually rises above the liquid level. As the scum moves along the upper surface of the second baffle 400, water in the scum flows back into the first region 130 under the action of gravity along the second baffle 400, thereby draining the water. This reduces the water content of the scum in the scum trough 200 and improves the separation of the scum from the wastewater.

[0036] At the same time, since the inclined section 420 is gradually raised, the resistance encountered by the scum during movement increases, the movement speed decreases, and the scum gradually accumulates on the inclined section 420. The scum is squeezed against each other, thereby achieving the effect of squeezing and dehydration, further reducing the water content between the scum.

[0037] Furthermore, during use of the electrolytic flotation device provided in an embodiment of the present application, in order to facilitate the scraper 610 to scrape the scum on the surface of the wastewater onto the second baffle 400, it is necessary to control the wastewater water level in the first area 130 so that the horizontal section 410 of the second baffle 400 is located slightly below the junction of the water surface and the scum. At the same time, the end of the inclined section 420 away from the horizontal section 410 needs to be higher than the water surface, so that the dehydration effect of the scum is better. Moreover, by adjusting the temperature and humidity of the external environment, the water vapor in the scum exposed to the atmosphere can be evaporated, thereby further reducing the water content between the scum.

[0038] In some specific embodiments, the second partition plate 400 further includes a guide section 430 connected to the inclined section 420. Figure 7 and Figure 8 As shown, the wire segment is bent toward the slag chute 200 to provide a guide for the slag, and the slag can fall into the slag chute 200 along the guide segment 430 .

[0039] In some preferred embodiments, a flap 700 is rotatably connected to the tank body 100, which can be referred to Figure 8 As shown, the flap 700 is located on the upper surface of the inclined section 420, and the width direction of the flap 700 is parallel to the width direction of the second partition 400. The flap 700 is located on the moving path of the scraper 610. The flap 700 can rotate under the push of the scraper 610 to avoid the scraper 610, and the scraper 610 can smoothly pass over the flap 700.

[0040] The flap 700 is located on the moving path of the scraper 610, that is, the flap 700 is located on the moving path of the scum. In the process of the scraper 610 pushing the scum to move on the upper surface of the second partition 400, the flap 700 can rotate to avoid the scraper 610, so that both the scraper 610 and the scum can smoothly pass over the flap 700. The flap 700 is located on the upper surface of the inclined section 420, which can prevent the scum above the inclined section 420 from falling back to the horizontal section 410 or even the first area 130 under the action of gravity, thereby further reducing the floc content in the wastewater in the first area 130.

[0041] In some preferred embodiments, a portion of the flap 700 near the inclined section 420 is hollowed out. The hollowed-out structure can facilitate the water filtered from the scum to flow back into the first area 130 , thereby reducing the water content in the slag trough 200 .

[0042] The hollowed-out structure on the flap 700 may be a filter structure provided on the flap 700. For example, a corresponding mounting opening is provided on the flap 700, and the filter is installed at the mounting opening. In other embodiments, the hollowed-out structure may also be a corresponding through hole provided directly on the flap 700.

[0043] After the flap 700 rotates under the push of the scraper 610, the flap 700 may or may not be reset after the pushing force of the scraper 610 disappears. In some embodiments, after the flap 700 is separated from the scraper 610, the flap 700 can be reset to the state before rotation to cooperate with the next scraper 610. The flap 700 is connected to an elastic member, such as a spring, to achieve the reset effect. In other embodiments, after the flap 700 is separated from the scraper 610, the flap 700 does not reset, and the flap 700 remains in the rotated state until the next scraper 610 continues to push the flap 700 to rotate. The rotatable flap 700 does not cause excessive obstruction to the movement of the scraper 610, and at the same time, it can prevent the scum from falling back into the first area 130 under the action of gravity.

[0044] In some embodiments, the width of the second partition 400 remains constant. In other embodiments, the width of the second partition 400 gradually decreases from the first region 130 to the second region 140. As the scraper 610 gradually pushes the scum on the upper surface of the second partition 400 to above the scum discharge chute 200, the scum is gradually squeezed together due to the decreasing width of the second partition 400, and the degree of squeezing becomes increasingly stronger. The squeezed scum can squeeze and dehydrate the water in the scum, thereby further reducing the water content in the scum.

[0045] The electrolysis device 500 is entirely disposed in the first area 130. In some preferred embodiments, the electrolysis device 500 is disposed adjacent to the first separator 300. The proximity of the electrolysis device 500 to the first separator 300 allows the electrolytic bubbles generated by the electrolysis device 500 to be disposed adjacent to the first separator 300, thereby increasing the probability that flocs that have re-entered the wastewater will resurface, thereby reducing the number of flocs that pass through the water outlet 310.

[0046] The electrolysis device 500 includes a plurality of spaced-apart electrode plates, which serve as negative and positive plates, respectively, for providing a DC electric field in the wastewater to electrolyze the wastewater and generate electrolytic bubbles. Figure 6 As shown, the electrode plate of the electrolysis device 500 is provided with a plurality of through holes, which can increase the reaction area and establish a water flow channel; moreover, these through holes can also reduce the turbulent kinetic energy of the water flow, avoid the flocs from breaking, and make the volume of the flocs as large as possible to facilitate the scraper 610 to push it onto the second partition 400.

[0047] The water inlet 110 and the water outlet 310 are located at opposite ends of the first region 130, with the water inlet 110 positioned near the bottom of the tank body 100, and the water outlet 310 positioned in a portion of the first baffle 300 away from the bottom of the tank body 100. That is, the water outlet 310 is positioned away from the bottom of the tank body 100. The water inlet 110 and the water outlet 310 are positioned as far apart in height as possible to extend the water flow path, allowing the electrolytic bubbles ample time to capture flocs, improving the electrolytic flotation effect, and producing more scum with good floating properties, thereby reducing the probability of the scum re-entering the wastewater.

[0048] In addition, the water inlet 310 and the water inlet 110 are located at opposite ends of the first partition 300 in the width direction. The water inlet 310 and the water inlet 110 are also spaced as far apart as possible in the width direction to further improve the flow path of the water flow and increase the residence time of the flocs in the first area 130.

[0049] In some embodiments, the slag chute 200 communicates with the external environment through a slag outlet 150 on the sidewall of the tank body 100, and the slag in the slag chute 200 is discharged to the outside through the slag outlet 150. The bottom of the slag chute 200 is inclined so that the slag in the slag chute 200 can slide out of the slag outlet 150 under the action of gravity. The bottom of the slag chute 200 is inclined, and the portion of the bottom of the slag chute 200 near the slag outlet 150 is at the lowest position, thereby ensuring that the slag in the slag chute 200 can flow toward the slag outlet 150 under the action of gravity.

[0050] When the second partition plate 400 is provided with the inclined section 420 , the moisture content of the slag in the slag chute 200 is further reduced. By tilting the bottom of the slag chute 200 , the slag can be discharged smoothly even without water lubrication.

[0051] In some embodiments of this application, reference may be made to Figures 5 to 7 As shown, a portion of the second baffle 400 extends above the first region 130, forming an eave above the water outlet 310. When the scraper 610 pushes the scum to the upper surface of the second baffle 400, even if the scum is disturbed and sinks back into the wastewater, the location where it sinks into the wastewater is farther from the water outlet 310 on the first baffle 300. This prolongs the time it takes for the flocs to reach the water outlet 310, allowing the electrolytic bubbles more time to re-intercept the flocs and allow them to float back up.

[0052] Preferably, the slag chute 200 includes an adjustment plate 210 slidably mounted on the wall of the slag chute 200. The adjustment plate 210 moves along the depth direction of the slag chute 200 in coordination with the wall of the slag chute 200 to adjust the depth of the slag chute 200. The slag chute 200 is located in the second region 140. By adjusting the depth of the slag chute 200, the distance between the upper notch of the slag chute 200 and the water level in the second region 140 can be adjusted, so that scum on the surface of the wastewater in the second region 140 falls into the slag chute 200.

[0053] Even if most of the scum has been processed in the first area 130, some may still pass through the water inlet 310 and enter the second area 140. The depth of the scum trough 200 is adjustable. If excessive scum accumulates on the surface of the second area 140, the scraper 610 can be used to temporarily remove the scum from the first area 130, clear the scum trough 200, and then adjust the trough walls 200 so that the opening is below the water level in the second area 140. This allows scum on the surface of the wastewater in the second area 140 to flow into the trough 200, thereby clearing the scum in the second area 140. This step is performed separately from the normal wastewater treatment process to prevent the wastewater in the second area 140 from increasing the water content of the scum that falls from the second baffle 400 into the scum trough 200.

[0054] In actual use, the second partition 400 blocks the second area 140, and it is not convenient for the operator to directly handle the scum in the second area 140. By adjusting the trough wall of the slag trough 200, the scum can be quickly and conveniently handled, further reducing the floc content in the wastewater.

[0055] In addition, since the second baffle 400 extends above the first area 130, after the scum falls into the first area 130, it cannot continue to float to the surface of the wastewater due to the obstruction of the second baffle 400 above. Instead, the scum flows through the water outlet 310 into the second area 140 and floats on the surface of the wastewater in the second area 140. In conjunction with the depth-adjustable scum discharge trough 200, the scum is processed to prevent the scum from sinking back into the wastewater in the first area 130, passing through the water outlet 310 into the second area 140 before floating, and finally sinking to the bottom of the second area 140 and being discharged through the drain outlet 120.

[0056] In some embodiments, the adjustment plate 210 is connected to an operating rod 800. Figure 6 As shown, the operating rod 800 extends outside the tank body 100 , and the operator can control the depth of the slag chute 200 by controlling the movement of the operating rod 800 directly outside the tank body 100 .

[0057] Furthermore, a transparent window 160 is provided on the side wall of the pool body 100, and the transparent window 160 corresponds to the adjustment plate 210. The operator can directly observe the position of the adjustment plate 210 through the transparent window 160, so as to facilitate the position adjustment of the adjustment plate 210; the operator can also observe the scum on the surface of the wastewater in the second area 140 through the transparent window 160 to determine the timing for cleaning the scum.

[0058] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
