An integrated operation model of flotation, adsorption and impurity removal is adopted to quickly complete the flotation treatment of oily wastewater.

Description

Technical Field

[0001] The invention relates to the technical field of chemical wastewater treatment, in particular to a chemical wastewater treatment reaction device. Background Art

[0002] Chemical wastewater is wastewater generated in the chemical industry, among which oily wastewater is wastewater generated during certain chemical reactions. This type of wastewater contains a large amount of grease and other related pollutants, and these greases will solidify after cooling. Therefore, in order to prevent oily wastewater from causing serious pollution to water bodies, soil and air, and affecting the ecosystem and human health, it is necessary to flotation treat the oily wastewater before discharging it to effectively remove grease and other pollutants in the water, thereby reducing the pollution of water bodies by sewage and protecting the ecological environment.

[0003] At present, there are the following disadvantages in the flotation treatment of oily wastewater: 1. When flotating oily wastewater, small bubbles are usually introduced into the wastewater first, so that the bubbles combine with oil droplets to form an oil droplet-bubble complex, so that the volume of oil impurities increases and the buoyancy is enhanced, so that they float to the water surface quickly. The above operation usually uses only small bubbles of the same size to float oily wastewater, and oil droplets of different sizes have different buoyancy and rising speeds during the flotation process. Small bubbles of a single size cannot effectively capture larger or smaller oil droplets, resulting in reduced separation efficiency, and poor adaptability to the flow rate of oily wastewater, thereby limiting its application scope; 2. After the flotation of oily wastewater is completed, a scraper is needed to concentrate the bubbles with oil and then scrape them off. Scraping the bubbles only by a scraper requires fine adjustment of the height, angle and speed of the scraper, thereby increasing the complexity of the operation, and the scraper will damage the bubbles during the scraping process, so that part of the oil may return to the water phase, causing the treated water quality to be polluted again, affecting the flotation effect.

First, through one-time synchronous fixation and centralized installation, the operation complexity is reduced, and then the bubbles are adapted to different oil droplets through step-by-step flotation. The air outlet position is switched by rotation to achieve uniform distribution of bubbles, so that the two cooperate to achieve more thorough oil-water separation to meet higher emission standards. Finally, after the flotation is completed, the upper sewage is directly extracted to cool and solidify the oil and filter it layer by layer, effectively reducing the risk of re-pollution, thereby optimizing the separation of oil and solid impurities, and simplifying the subsequent treatment process, thereby achieving efficient, convenient and environmentally friendly sewage treatment.

[0018] 2. The chemical wastewater treatment reaction device can fix all conical carriers synchronously at one time through the main body mechanism, and directly install all parts in the treatment tank at one time by moving the central drum, and provide positioning for the central drum during the installation process, which can significantly reduce the time and manpower required for installation, reduce the complexity of operation, and improve work efficiency.

[0020] 4. The chemical wastewater treatment reaction device, through the coordinated use of the suction mechanism and the impurity removal mechanism, directly extracts the upper sewage after flotation, so that the sewage and the grease after flotation are pumped to the top, and then the grease after flotation is cooled and solidified. At the same time, the extracted sewage is filtered layer by layer, and the solidified grease is automatically discharged after filtration, which can reduce the risk of re-contamination of grease, and effectively separate grease and solid impurities, reducing the secondary pollution that may be generated in the sewage treatment process. At the same time, through solidification and automatic discharge, the subsequent grease treatment process can be simplified and the complexity of the system can be reduced.

[0036] See also Figure 2 , Figure 3 and Figure 6 The matching part 43 includes a conical carrier plate 431, an annular filter plate 432, a socket 433 and a spring plug rod 434. A plurality of conical carrier plates 431 located in the treatment tank 2 are arranged in a linear array from top to bottom on the outer ring wall of the central rotating cylinder 411. An annular filter plate 432 is fixedly installed on the outer ring wall of the conical carrier plate 431. A plurality of filter holes (not shown in the figure) are evenly distributed on the upper end surface of the annular filter plate 432. A plurality of lock holes are opened in a circular array on the inner ring wall of the conical carrier plate 431. Sockets 433 corresponding to the lock holes are opened through the central rotating cylinder 411. A spring plug rod 434 is slidably installed in the socket 433.

[0037] See also Figure 2 , Figure 3 and Figure 7 The alignment part 44 includes an isolation plate 441, a collecting inclined plate 442, a liquid inlet 443, an alignment block 444, a connecting column 445 and a transmission rod 446. The isolation plate 441 located directly below the conical carrier plate 431 is installed on the central rotating cylinder 411 through a bearing, and an alignment groove is penetrated through the upper end surface of the isolation plate 441. The collecting inclined plate 442 connected to the central rotating cylinder 411 through a bearing is fixedly installed on the upper end surface of the isolation plate 441.

The connecting column 445 is fixedly installed on the lower end surface of the central rotating cylinder 411, and the transmission rod 446 is fixedly installed on the lower end surface of the connecting column 445.

[0038] During the specific operation, before installing the central rotating cylinder 411, the center of the conical carrier plate 431 is first passed through the central rotating cylinder 411, and the conical carrier plate 431 is placed at the corresponding insertion hole 433. After the positions of all the conical carrier plates 431 are determined, the central insert cylinder 421 is first inserted from the upper end of the central rotating cylinder 411, so that the lower end of the central rotating cylinder 411 squeezes all the circumferential spring plug rods 434 on the same horizontal plane outward at the same time, thereby pushing the spring plug rods 434 out of the insertion hole 433 and inserting them into the corresponding lock hole, so as to fix the position of the conical carrier plate 431, and when the fixed circular plate 422 is in contact with the upper end of the central rotating cylinder 411, the fixed circular plate 422 is fixed to the central rotating cylinder 411 with bolts, so as to fix the position of the central insert cylinder 421.

[0039] After the installation of the conical carrier plate 431 is completed, the central drum 411 can be directly hoisted into the processing tank 2 by an external crane, and during the descent of the central drum 411, the installation position of the central drum 411 is determined by aligning the alignment grooves on the isolation plate 441 with the alignment blocks 444, so that all parts can be installed in the processing tank 2 at one time by moving the central drum 411, which significantly reduces the time and manpower required for installation and reduces the complexity of operation, while ensuring the uniform position and alignment of the carrier plate and other components, making subsequent maintenance and inspection more convenient.

[0040] See also Figure 2 , Figure 3 and Figure 7 The flotation section 45 includes a central rotating rod 451, a stirring rod 452, an air outlet valve 453 and an air inlet pipe 454. The central rotating rod 451 is fixedly installed on the lower end surface of the transmission rod 446. The lower end of the central rotating rod 451 passes through the lower end surface of the processing tank 2 and is connected thereto through a bearing. A plurality of stirring rods 452 are evenly fixedly installed on the central rotating rod 451. A plurality of air outlet valves 453 are evenly distributed on the stirring rod 452 in an array. An air cavity connected to the air outlet valve 453 is commonly provided in the plurality of stirring rods 452 and the central rotating rod 451. An air inlet pipe 454 connected thereto is rotatably plugged into the lower end of the air cavity.

[0041] During specific operation, when it is necessary to perform flotation treatment on the oily wastewater, the oily wastewater to be treated is first directly injected into the treatment tank 2 through the liquid inlet 443, and when the wastewater liquid level reaches the connecting column 445, the injection of wastewater is stopped, and then the external air pump is started to provide airflow to the air inlet pipe 454, and the airflow will move to the air outlet valve 453 through the air cavity in the several stirring rods 452 and the central rotating rod 451, so that the airflow is ejected from the air outlet valve 453 and bubbles are formed, so as to perform flotation treatment on the oily wastewater, and then the size of the bubbles ejected from the air outlet valve 453 is controlled by controlling the output of the external air pump and the size of the air holes of the air outlet valve 453, so as to implement step-by-step flotation of the oily wastewater from large to small bubbles, so that the bubbles adapt to the buoyancy characteristics of oil droplets of different sizes, so as to more effectively improve the efficiency of oil-water separation.

[0042] During the flotation process, the first motor 412 is started to rotate the central drum 411 through the first gear set, and the central drum 411 will drive the multiple conical carrier plates 431 and the central rotating rod 451 to rotate synchronously, and the isolation plate 441 is locked with the collecting inclined plate 442 by the cooperation of the alignment groove and the alignment block 444. During the rotation of the central rotating rod 451, the gas outlet valve 453 is driven to rotate continuously through the stirring rod 452, so that the gas outlet position is continuously switched during the flotation process, so that the flotation bubbles are evenly distributed in the oily wastewater, reducing the flotation dead corners in the treatment tank 2, which helps to make full use of the treatment space and improve the wastewater treatment efficiency.

[0043] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The extraction part 51 includes a liquid pump 511, a liquid discharge pipe 512 and a connecting pipe 513.

The liquid discharge pipe 512 connected to the liquid discharge end of the liquid pump 511 is fixedly installed on the upper end surface of the processing tank 2. The connecting pipe 513 is fixedly installed on the extraction end of the liquid pump 511. The lower end of the connecting pipe 513 passes through the lower end surface of the central insert cylinder 421 and then passes through the central rotating cylinder 411.

[0044] See also Figure 2 , Figure 3 and Figure 7 The suction part 52 includes a scraper 521, adsorption holes 522 and a connecting cavity 523. A scraper 521 with a cavity inside and symmetrical front and back is fixedly installed on the outer ring wall of the connecting column 445. A plurality of adsorption holes 522 are evenly distributed on the scraper 521 in an array manner. A connecting cavity 523 connected to the cavity of the scraper 521 is opened at the center of the connecting column 445, and the lower end of the connecting pipe 513 is rotatably inserted into the upper end of the connecting cavity 523.

[0045] During specific operation, when the flotation section 45 is flotating the oily wastewater, the liquid pump 511 is started to provide suction to the connecting cavity 523 through the connecting pipe 513. At the same time, the rotating section 41 rotates the connecting column 445, thereby driving the scraper 521 to rotate with the central drum 411 as the center point. During the rotation of the scraper 521, the wastewater is extracted upward from the adsorption hole 522 through suction. During the extraction process, the upper layer of wastewater will rise synchronously with the emulsion or oil surface formed at the upper end of the wastewater after flotation.

[0046] Then, the liquid pump 511 discharges the mixed sewage after extraction into the upper end of the treatment tank 2 through the liquid discharge pipe 512. At this time, the external refrigerator (not shown in the figure) is started to provide a cold air flow for the upper half of the treatment tank 2. When the sewage falls to the top of the conical carrier plate 431, the oil after flotation will be cooled and solidified, and the sewage will carry the solidified oil along the inclined surface of the conical carrier plate 431 to the annular filter plate 432, so that the annular filter plate 432 filters the solidified oil. Then the sewage needs to be filtered by multiple layers of annular filter plates 432, so as to filter the sewage extracted upward layer by layer to more effectively separate the oil and solid impurities.

[0047] See also Figure 2 and Figure 3 The filter part 61 includes a debris removal hole 611, a supporting cross bar 612 and a debris removal plate 613. The debris removal holes 611 corresponding to the conical carrier plate 431 are fixedly installed on the processing tank 2, and an electronic valve is arranged in the debris removal hole 611. The supporting cross bar 612 corresponding to the debris removal holes 611 is fixedly installed on the inner ring wall of the processing tank 2, and the debris removal plate 613 for scraping the upper end surface of the conical carrier plate 431 and the annular filter plate 432 is fixedly installed at the lower end of the supporting cross bar 612.

[0048] See also Figure 2 and Figure 3 The recovery part 62 includes a collecting square tube 621 and a connecting tube 622. The collecting square tube 621 located at the lowest point of the contact between the collecting inclined plate 442 and the processing tank 2 is fixedly installed on the outer ring wall of the processing tank 2. The collecting square tube 621 is connected to the processing tank 2 through the connecting tube 622, and the lower end of the connecting tube 622 is located above the stirring rod 452.

[0049] During specific operation, when the annular filter plate 432 is filtering the solidified grease, the electronic valve in the impurity discharge hole 611 is in a closed state to prevent sewage from being discharged. At this time, the rotating part 41 will rotate with the annular filter plate 432 and the conical carrier plate 431, so that the impurity discharge plate 613 scrapes the impurities attached to the surfaces of the annular filter plate 432 and the conical carrier plate 431. After the annular filter plate 432 completes the filtration, the electronic valve is opened, and the impurities scraped from the impurity discharge plate 613 are extracted through an external extractor, so that the solidified grease after filtration is automatically discharged, which can reduce the risk of re-contamination of grease and reduce the secondary pollution that may be generated during sewage treatment.

[0050] The filtered sewage will fall onto the upper end surface of the collecting inclined plate 442, and flow along the inclined surface of the collecting inclined plate 442 into the collecting square tube 621. At this time, the flotation treatment of the oily sewage has been completed, and the pumping pump 511 stops extracting the sewage, and then opens the discharge hole 3 to discharge the treated sewage, and the filtered sewage will be discharged through the connecting pipe 622 and the discharge hole 3, and the next group of sewage can be floated.

[0051] See also Figure 1-Figure 7 Working principle: When the oily wastewater needs to be flotated, the oily wastewater to be treated is first directly injected into the treatment tank 2 through the liquid inlet 443, and when the wastewater liquid level reaches the connecting column 445, the injection of wastewater is stopped, and the flotation part 45 is used to perform step-by-step flotation of the oily wastewater with bubbles from large to small, and the rotating part 41 cooperates with the flotation part 45 to make the flotation bubbles evenly distributed in the oily wastewater.

[0052] During the flotation of the oily wastewater by the flotation section 45, the pumping pump 511 is started to carry the emulsion or oil surface formed at the upper end of the wastewater after flotation through the upper layer of the wastewater through the suction mechanism 5, and the wastewater drawn upward is filtered layer by layer through the matching section 43 to more effectively separate grease and solid impurities.

[0053] At the same time, the impurity removal plate 613 scrapes the impurities attached to the surfaces of the annular filter plate 432 and the conical carrier plate 431. After the annular filter plate 432 completes the filtration, the electronic valve is opened, and the impurities scraped from the impurity removal plate 613 are extracted through an external extractor, so that the solidified grease after filtration is automatically discharged, and the filtered sewage will enter the flotation area through the recovery part 62. The discharge hole 3 is opened to discharge the treated sewage, and the flotation of the next group of sewage can be carried out.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
