[0020] The embodiments of the utility model will be described in detail below with reference to the drawings. It should be clear that the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] As Figs. 1-2 Indicated, in some illustrative embodiments, an adjustable agglomeration sludge reactor is provided, applied in the biochemical tank of the wastewater treatment plant of the petroleum chemical enterprise, comprising: cyclone pipe 100, adjusting overflow pipe 200, water inlet pipeline 300, overflow pipeline 400, water outlet pipeline 500, fixed side flange 600, moving side flange 700, adjusting bolt assembly 800, submersible pump 900, centrifugal pump 1000, first pressure gauge 1100, second pressure gauge 1200, first flowmeter 1300, second flowmeter 1400 and support telescopic rod 1500.

[0022] The cyclone tube 100 is used to separate the wastewater discharged from the biochemical tank 1600, and the activated sludge in an abnormal state is separated to the overflow pipe 400 for later unified treatment, and the sludge in a good state is discharged through the effluent pipe 500 and returned to the biochemical tank 1600.

[0023] The water inlet pipe 300 is used to transport the petrochemical wastewater from the biochemical tank 1600 to the cyclone tube 100, and the side of the cyclone tube 100 is provided with the feed inlet 110, and the water inlet pipe 300 is connected with the feed inlet 110.

[0024] Specifically, the water inlet pipe 300 includes a front section pipe 310 and a rear section pipe 320. One end of the front section pipe 310 is connected with the liquid outlet of the submersible pump 900, and the other end of the front section pipe 310 is connected with the liquid inlet of the centrifugal pump 1000. The submersible pump 900 is located in the biochemical tank 1600 and is used to extract wastewater containing activated sludge. The liquid outlet of the centrifugal pump 1000 is connected with the rear section pipe 320, and the rear section pipe 320 is connected with the feed inlet 110 through a flange to send the wastewater into the cyclone tube 100.

[0025] The submersible pump 900 extracts the petrochemical wastewater containing activated sludge from the biochemical tank 1600, and the wastewater is transported to the centrifugal pump 1000 through the front section pipe 310. The centrifugal pump 1000 pressurizes the wastewater to increase its pressure and flow rate. The pressurized wastewater is pumped into the feed inlet 110 of the cyclone tube 100 through the rear section pipe 320. By pressurizing through the centrifugal pump 1000, the delivery pressure and flow rate of the wastewater can be significantly improved, ensuring that the wastewater can be quickly and effectively transported to the cyclone tube 100. The combination of the submersible pump 900 and the centrifugal pump 1000 can optimize energy consumption. The submersible pump 900 is responsible for pumping water from a lower position, while the centrifugal pump 1000 is responsible for providing the necessary pressure. Both work together to improve the energy efficiency of the overall system.

[0026] The bottom of the cyclone tube 100 is provided with the underflow port 120, and the effluent pipe 500 is connected with the underflow port 120. The outlet of the cyclone tube 100 has two, which are the overflow port 130 and the underflow port 120. The overflow port 130 is the bottom end pipe port of the adjusting overflow pipe 200, and the top end pipe port of the adjusting overflow pipe 200 is connected with the overflow pipe 400.

[0027] The first pressure gauge 1100 is arranged on the feed inlet 110, and the second pressure gauge 1200 is arranged on the adjusting overflow pipe 200. The first flow meter 1300 is arranged on the rear section pipe 320, and the second flow meter 1400 is arranged on the effluent pipe 500.

[0028] The submersible pump 900 pumps the wastewater from the biochemical tank 1600, and firstly passes through the centrifugal pump 1000. The actual pressure value can be measured by the first pressure gauge 1100 on the feed inlet 110. Different pressure conditions will affect the split ratio and separation effect. The first flow meter 1300 is arranged on the water inlet pipeline 300, which can record the total flow into the cyclone tube 100 under the current conditions. Flow is one of the important factors affecting the cyclone separator. The first flow meter 1300 and the first pressure gauge 1100 record different flow and pressure values under different conditions.

[0029] The activated sludge for treating petrochemical wastewater enters the cyclone tube 100 through the water inlet pipeline 300. Under the action of centrifugal force, the activated sludge rotates at high speed in the cyclone tube 100. Under different pressure conditions, the rotation speed in the cyclone tube 100 is different, which will result in different split ratios. The agglomerated sludge in good condition will gradually move downward through high-speed rotation and be discharged from the underflow port 120. The sludge in abnormal condition is mostly sludge aging and sludge disintegration. Such sludge has small density and will form inner cyclone to be discharged from the overflow port 130.

[0030] The activated sludge in good condition will return to the biochemical tank 1600 from the underflow port 120 through the water outlet pipeline 500. The second flow meter 1400 is arranged on the water outlet pipeline 500. The reading can be taken after the overall device is stable. The value is the underflow flow. The overflow flow can be calculated by the first flow meter 1300 and the second flow meter 1400, so the split ratio of the overflow port 130 and the underflow port 120 can be determined.

[0031] The activated sludge in abnormal condition will be discharged from the cyclone tube 100 through the adjusting overflow pipe 200 from the overflow pipeline 400. Then the sludge in abnormal condition is uniformly treated and eliminated. The second pressure gauge 1200 is arranged on the adjusting overflow pipe 200 to monitor the pressure value of the adjusting overflow pipe 200, so as to ensure the normal operation of the overall device.

[0032] In the face of different petrochemical enterprise sewage treatment plant, the activated sludge state in the biochemical pool 1600 is inconsistent, and the separation effect of the cyclone tube 100 may not be optimal, so a detachable adjustable overflow pipe 200 is designed in this embodiment. Specifically, the top of the cyclone tube 100 is provided with a support pipe 140 which is in communication with the internal space of the cyclone tube 100, and the top end port of the support pipe 140 is provided with a fixed side flange 600. The top end port of the adjustable overflow pipe 200 is connected with the overflow pipe 400, and the bottom end port of the adjustable overflow pipe 200 penetrates through the support pipe 140 and extends into the cyclone tube 100. The bottom end port of the adjustable overflow pipe 200 is the overflow port 130 of the cyclone tube, and the adjustable overflow pipe 200 is provided with a movable side flange 700. The fixed side flange 600 and the movable side flange 700 are connected through an adjusting bolt assembly 800, the height of the movable side flange 700 is adjusted through the adjusting bolt assembly 800, and then the distance between the fixed side flange 600 and the movable side flange 700 is adjusted, and finally the extension depth of the overflow port 130 is adjusted.

[0033] In this embodiment, the fixed side flange 600 and the movable side flange 700 are connected to form an adjustable area. Since the adjustable overflow pipe 200 is connected to the movable side flange 700, the adjustable overflow pipe 200 can be made deeper into the cyclone tube 100 by reducing the distance between the movable side flange 700 and the fixed side flange 600, and the overflow port 130 will be deeper into the cyclone tube 100. If you want to take out the adjustable overflow pipe 200 by a distance, you can increase the distance between the fixed side flange 600 and the movable side flange 700, so that the overflow port 130 will be closer to the top end of the cyclone tube 100. Changing the depth of the overflow port 130 will directly affect the split ratio of the cyclone tube 100, and directly affect the separation efficiency of the adjustable agglomeration sludge reactor of the present application.

[0034] If the ideal separation effect is still not achieved, different pipe diameters of the adjustable overflow pipe 200 can also be replaced. The pipe diameter of the adjustable overflow pipe 200 is also one of the important factors affecting the split ratio. The structure design of the movable side flange 700, the support pipe 140 and the fixed side flange 600 makes the replacement of the adjustable overflow pipe 200 convenient, and the appropriate pipe diameter and overflow port depth can be determined through experimental test for different water quality.

[0035] The adjusting bolt assembly 800 includes a bolt 810, a first nut 820, a second nut 860, a guide telescopic rod 830, a scale 840 and a marker block 850.

[0036] The mobile flange 700 is provided with a threaded hole, and the bolt 810 is fixed to the mobile flange 700 in a threaded connection manner, and the head of the bolt 810 is located at the top of the mobile flange 700, and the rod of the bolt 810 passes through the threaded hole. The fixed flange 600 is provided with a through hole, and the bottom end of the rod of the bolt 810 passes through the through hole and is screwed with the second nut 860, and the first nut 820 is arranged on the rod of the bolt 810, and the first nut 820 and the second nut 860 are located on the upper and lower sides of the fixed flange 600, respectively.

[0037] When it is necessary to adjust the distance between the fixed flange 600 and the mobile flange 700, the first nut 820 and the second nut 860 are screwed, and the position of the fixed flange 600 on the bolt 810 is adjusted by adjusting the positions of the two nuts on the bolt 810, so as to finally adjust the distance between the fixed flange 600 and the mobile flange 700. By adjusting the relative positions of the first nut 820 and the second nut 860 on the bolt 810, the depth of the overflow port 130 can be changed, providing a large adjustment range and adjustment flexibility, and the operator only needs to use a simple tool such as a wrench to easily screw the nut, without the need for complex equipment, so that the adjustment process is quick and simple. At the same time, the threaded connection can provide stable fixing effect after adjustment, and is not easy to loosen due to vibration and other factors, ensuring the stability of long-term operation of the equipment. Compared with other adjustment mechanisms such as hydraulic or pneumatic systems, the threaded adjustment assembly is more compact, saves installation space, has a simple structure, is not easy to damage, and even if it needs to be replaced, the cost is relatively low.

[0038] The guide telescopic rod 830 is arranged between the fixed flange 600 and the mobile flange 700, the fixed end of the guide telescopic rod 830 is connected with the fixed flange 600, and the mobile end of the guide telescopic rod 830 is connected with the mobile flange 700, so that the movement of the mobile flange 700 during adjustment is along the axial direction of the guide telescopic rod 830, thereby realizing accurate guiding and supporting. The scale 840 is arranged on the lower surface of the mobile flange 700 and moves together with the mobile flange 700, and the marker block 850 is arranged on the fixed part of the guide telescopic rod 830, facilitating reading of the scale 840. The scale 840 provides direct visual feedback, and the operator can easily read and adjust the distance without the need for additional measuring tools

[0039] The support telescopic rod 1500 is a telescopic rod structure, usually composed of multiple telescopic pipe segments, which can adjust the length as needed. The moving end of the support telescopic rod 1500 is connected with the overflow pipeline 400, and the fixed end of the support telescopic rod 1500 is arranged on the ground through a pedestal, which is a stable support structure for ensuring the stability of the support telescopic rod 1500 during adjustment and operation. The support telescopic rod 1500 provides stable support and ensures the stability of the entire overflow pipeline system during operation.

[0040] In this embodiment, the activated sludge in good condition is returned to the biochemical tank 1600, and the activated sludge in abnormal condition is separated and eliminated. By adjusting the pipe diameter of the adjusting overflow pipe 200 and the depth of the overflow port 130, the split ratio of the cyclone pipe 100 can be adjusted, and different separation effects can be achieved through different split ratios. The most suitable separation ratio can be found for different water qualities to achieve ideal separation effect, greatly improving the separation efficiency of the oil and chemical enterprise wastewater treatment plant and saving energy and reducing consumption.

[0041] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
