Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and relates to a device and method for electro-oxidation treatment of sodium phenolate sewage. Background Art

[0002] In the process of oil exploitation and processing, due to the presence of a small amount of phenolic compounds in crude oil, alkaline substances are added for neutralization during the desalting and dehydration process. The reaction between phenolic compounds and sodium hydroxide produces sodium phenolate, resulting in sodium phenolate in the wastewater. Sodium phenolate sewage is an industrial wastewater containing high concentrations of phenol and its derivatives, with characteristics such as high toxicity, high chromaticity, and difficult degradation, causing serious harm to the environment and ecosystem. Therefore, electro-oxidation treatment of sodium phenolate sewage is required.

[0003] Currently, when electro-oxidation treatment is carried out on sodium phenolate sewage, since oil and other large impurities in the sewage need to be removed before electro-oxidation treatment, chemicals are used for oil removal through a certain ratio of mixing. Through the chemical reaction after mixing, impurities or oil stains are precipitated and polymerized to form a jelly-like substance for filtration and removal. However, in the existing method of adding chemicals, manual weight ratio addition is required, and manual measurement and ratio are needed each time, which is rather cumbersome in operation and has a low treatment efficiency.

[0014] The present invention also provides a method for electro-oxidation treatment of sodium phenoxide sewage, and the specific steps are as follows:

[0015] S1: Sodium hydroxide, a coagulant, and a flocculant are respectively added into the three blanking cylinders from right to left. The chemicals in the blanking cylinders enter the injection trough through the discharge ports.

[0016] S2: The pipeline of the sodium phenoxide sewage is connected to the liquid inlet pipe, and the sodium phenoxide sewage will enter the rightmost chamber through the liquid inlet pipe.

[0017] S3: Pull the right connecting rod forward, the first elastic member is compressed. When the connecting rod moves forward, it drives the connecting rack to move forward.

Then, according to the above operation, the connecting rod is pulled to move for the addition of the medicament. Repeating this process, after passing through the three chambers on the right, the sewage reacts with sodium hydroxide, coagulant, and flocculant in sequence, causing the internal oil impurities to form flocs.

[0019] S5: When the liquid extraction pump on the left operates, it can transport the sewage and flocs through the connecting pipe to above the material guiding frame. The flocs are blocked by the filter screen, and the sewage passes through the filter screen and enters the leftmost chamber.

[0020] S6: Connect the power supply of the connecting wire to make the conductive plate discharge, decompose the refractory organic matter remaining in the mineralization of the sewage to purify the water quality, make the sewage reach the discharge standard, open the valve at the drainage port, and discharge the purified water to complete the treatment of the sodium phenolate sewage.

[0021] The present invention has the following advantages: 1. When treating the sodium phenolate sewage, the present invention can add the medicament through the injection groove on the feeding block. Each time the added medicament just fills one injection groove, ensuring the consistency of the added amount of the medicament. There is no need for manual weighing, which is more convenient in operation and has higher treatment efficiency.

[0022] 2. When adding the sewage, the sewage will first enter the material guiding cylinder, and then the impurities mixed in the sewage can be separated through the screen, avoiding impurities from entering the chamber and affecting the treatment of the sewage. Description of the Drawings

Detailed implementation manners

[0034] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but do not limit the present invention.

[0035] A sodium phenoxide sewage electro-oxidation treatment device, as Figures 1-5 shown, includes a treatment box body 1, a separator plate 2, a sealing cover 21, a feeding frame 5, a filter screen 6, a liquid inlet pipe 7, a liquid extraction assembly, an electrolysis assembly and a feeding mechanism.

Three sealing covers 21 are connected to the top right side of the treatment box body 1. The three sealing covers 21 respectively block the three chambers on the right side of the treatment box body 1. A feeding frame 5 is connected to the upper right side of the leftmost chamber. A filter screen 6 is arranged at the rear side of the bottom of the feeding frame 5. The middle of the right side of the treatment box body 1 is communicated with a liquid inlet pipe 7. A drain port is opened on the left side of the treatment box body 1, and a valve is arranged at the drain port. A liquid extraction assembly is arranged on the treatment box body 1 for transmitting sewage. An electrolysis assembly for electrolyzing sewage is arranged in the leftmost chamber. A feeding mechanism for adding medicine is arranged on the sealing cover 21.

[0036] As Figure 2As shown in the figure, the liquid pumping assembly includes a liquid pump 31 and a connecting pipe 32. Three liquid pumps 31 are evenly spaced and connected to the rear side of the processing frame body 1. The liquid inlet end and the liquid outlet end of the liquid pump 31 are both connected to a connecting pipe 32. The liquid inlet end of the liquid pump 31 is arranged on the right side, and the liquid outlet end of the liquid pump 31 is arranged on the left side. The connecting pipes 32 on both sides of the liquid pump 31 are respectively connected to two adjacent chambers, so that when the liquid pump 31 operates, it can discharge the sewage in the right chamber into the left chamber through the connecting pipe 32. The connecting pipe 32 on the left side of the left liquid pump 31 is aligned above the material guiding frame 5.

[0037] As Figure 2 shown in the figure, the electrolysis assembly includes a connecting frame 41, a conductive plate 42 and a connecting wire 43. The connecting frame 41 is connected to the upper left part of the leftmost chamber. The conductive plates 42 are connected to both the front and rear sides of the connecting frame 41. The lower part of the conductive plate 42 extends into the leftmost chamber. The connecting wire 43 is connected to the conductive plate 42.

[0038] As Figure 4 and Figure 5 shown in the figure, the feeding mechanism includes a feeding cylinder 81, an outer cylinder 82, a feeding block 83, a first gear ring 84, a bottom plate 85, a connecting rod 86, a first elastic member 87, a connecting rack 88 and a top plate 89. The feeding cylinder 81 is connected to the top of the cover 21. The lower part of the feeding cylinder 81 is connected to the outer cylinder 82. The outer cylinder 82 passes through the cover 21 and extends into the processing frame body 1. The bottom of the feeding cylinder 81 is connected to the top plate 89. An outlet is provided on the right side of the top plate 89. The bottom of the outer cylinder 82 is connected to the bottom plate 85. A discharge port is provided on the left side of the bottom plate 85. The feeding block 83 is rotatably connected inside the outer cylinder 82. Two feeding grooves are evenly spaced on the feeding block 83. The top of the feeding groove can rotate to align with the outlet, and the bottom of the feeding groove can rotate to align with the discharge port. The outer ring of the feeding block 83 is connected to the first gear ring 84 through a one-way clutch. The connecting rack 88 is slidably connected to the right side of the outer cylinder 82. The connecting rack 88 meshes with the first gear ring 84. The connecting rod 86 is connected to the front side of the connecting rack 88. The connecting rod 86 is slidably connected to the outer cylinder 82. A first elastic member 87 is connected between the connecting rod 86 and the outer cylinder 82. The first elastic member 87 is a compression spring.

[0039] When it is necessary to treat sodium phenolate sewage, this device can be used for treatment. Initially, sodium hydroxide, a coagulant, and a flocculant are respectively added into three feeding cylinders 81 from right to left. The chemicals in the feeding cylinders 81 will enter the injection trough through the discharge ports. During use, first connect the pipeline of the sodium phenolate sewage to the liquid inlet pipe 7. Subsequently, the sodium phenolate sewage will enter the rightmost chamber through the liquid inlet pipe 7. After it is full, stop adding the sodium phenolate sewage. Then, the connecting rod 86 on the right can be pulled forward, and the first elastic member 87 is compressed. When the connecting rod 86 on the right moves forward, it drives the connecting rack 88 to move forward. The forward movement of the connecting rack 88 drives the first gear ring 84 to rotate. The rotation of the first gear ring 84 drives the feeding block 83 to rotate. When the connecting rack 88 moves until it disengages from the first gear ring 84, the feeding block 83 just rotates 180 degrees. At this time, the chemicals in the feeding block 83 will be added into the chamber, thus achieving the effect of adding chemicals. After adding the chemicals, release the connecting rack 88. At this time, under the action of the first elastic member 87, the connecting rack 88 resets and drives the first gear ring 84 to reverse. At this time, under the action of the one-way clutch, the feeding block 83 will not rotate. After the chemicals are added into the chamber, they react with the sewage in the chamber. After the reaction, the operation of the liquid extraction pump 31 can be controlled to send the sewage into the next chamber through the communicating pipe 32. Then, according to the above operation, pull the connecting rod 86 to move to add the chemicals. Repeat this process. After passing through the three chambers on the right, the sewage will react with sodium hydroxide, the coagulant, and the flocculant in sequence, so that the phenolic substances in the sewage react with the alkali to form sodium phenolate, and then the pollutants in the sewage form flocs through the coagulant. Finally, the flocs are connected to each other to form flocculent masses through the flocculant. When the liquid extraction pump 31 on the left operates, it can transport the sewage and the flocculent masses to above the guide frame 5 through the communicating pipe 32. The flocculent masses will be blocked by the filter screen 6, and the sewage will pass through the filter screen 6 and enter the leftmost chamber. At this time, the connecting wire 43 can be electrified to make the conductive plate 42 discharge, decomposing the refractory organic matter with mineralization residues in the sewage, thereby purifying the water quality and making the sewage meet the discharge standard. Then, open the valve at the drainage port to discharge the purified water. In this way, this device can be used for sewage treatment work, and during operation, the addition of sodium hydroxide, the coagulant, and the flocculant can be carried out quantitatively without manual weighing and addition, making the operation more convenient.

[0040] Such as Figure 6As shown in the figure, it further includes an impurity cleaning mechanism. The impurity cleaning mechanism includes a material guiding cylinder 91, a spiral feeding disk 92, a screen 93, a driving motor 94 and a material guiding plate 95. The material guiding cylinder 91 is connected to the right sealing cover 21. The material guiding cylinder 91 is communicated with the liquid inlet pipe 7. The driving motor 94 is installed on the top of the material guiding cylinder 91. The output shaft of the driving motor 94 is connected with the spiral feeding disk 92. The spiral feeding disk 92 is located inside the material guiding cylinder 91. The bottom of the material guiding cylinder 91 is connected with the screen 93. The front and rear sides of the upper part of the material guiding cylinder 91 are both connected with the material guiding plate 95. Openings are formed on the front and rear sides of the upper part of the material guiding cylinder 91. The upper part of the spiral feeding disk 92 is aligned with the openings, and the openings are aligned with the material guiding plate 95.

[0041] When adding sewage, the sewage will first enter the material guiding cylinder 91. The impurities mixed in the sewage will be blocked by the screen 93, while the sewage will pass through the screen 93. Subsequently, the driving motor 94 can be controlled to drive the spiral feeding disk 92 to rotate. When the spiral feeding disk 92 rotates, it will convey the impurities on the screen 93 upward. After being conveyed above the material guiding cylinder 91, they will pass through the openings above the material guiding cylinder 91 and enter the material guiding plate 95, and be discharged through the material guiding plate 95. In this way, the impurities mixed in the sewage can be treated.

[0042] As Figure 7 As shown in the figure, it further includes a transmission mechanism. The transmission mechanism includes a floating frame 101, a guide rod 102, a pressure receiving frame 103 and a pressing rod 104. Guide rods 102 are connected to the left and right sides of the bottom of the sealing cover 21. A floating frame 101 is slidably connected between the two guide rods 102. The floating frame 101 can slide up and down in the chamber. The rear side of the top of the floating frame 101 is connected with a pressing rod 104. The rear side of the connecting rack 88 is connected with a pressure receiving frame 103. When the pressing rod 104 moves upward, it will contact and press the pressure receiving frame 103 to move.

[0043] When the sewage enters the chamber, the buoyancy of the sewage will drive the floating frame 101 to move upward. When the floating frame 101 moves upward, it will drive the pressing rod 104 to move upward. When the pressing rod 104 moves upward, it will contact and press the pressure receiving frame 103 to move forward. The forward movement of the pressure receiving frame 103 drives the connecting rack 88 to move forward. In this way, the effect of automatically driving the connecting rack 88 to move can be achieved, making the operation more convenient.

[0044] As Figure 8As shown in the figure, it further includes a control feeding mechanism. The control feeding mechanism includes an L-shaped rack 111, a sealing frame 112, a sealing plate 113 and a second gear ring 114. The right side of the floating frame 101 on the right is connected with the L-shaped rack 111. The left side inside the liquid inlet pipe 7 is connected with the sealing frame 112. The sealing plate 113 is rotatably connected inside the sealing frame 112. After the sealing plate 113 rotates 180 degrees, it can cooperate with the sealing plate 113 to block the liquid inlet pipe 7. The outside of the sealing plate 113 is connected with the second gear ring 114. The second gear ring 114 is located at the moving track of the L-shaped rack 111, so that the L-shaped rack 111 can drive the second gear ring 114 to rotate when moving.

[0045] When the floating frame 101 moves upward, it will drive the L-shaped rack 111 to move upward. When the L-shaped rack 111 moves upward, it will engage with the second gear ring 114 and drive the second gear ring 114 to rotate. When the second gear ring 114 rotates, it will drive the sealing plate 113 to rotate. When the sealing plate 113 rotates, it will gradually cooperate with the sealing frame 112 to block the inside of the liquid inlet pipe 7. At this time, the chamber is already filled with sewage. In this way, the liquid inlet pipe 7 can be automatically blocked after the chamber is filled with sewage.

[0046] As Figure 8 As shown in the figure, it further includes a locking mechanism. The locking mechanism includes a clamping plate 121, a clamping column 122 and a second elastic member 123. The top right rear side of the rightmost floating frame 101 is connected with the clamping plate 121. A jack is opened in the upper part of the clamping plate 121. The right lower part of the rightmost material discharging cylinder 81 is slidably connected with the clamping column 122. The rear side of the clamping column 122 is frustum-shaped. When the clamping plate 121 moves upward, it will squeeze the conical surface of the clamping column 122. A second elastic member 123 is connected between the clamping column 122 and the material discharging cylinder 81. The second elastic member 123 is a connecting spring.

[0047] When the floating frame 101 moves upward, it will drive the clamping plate 121 to move upward. After the clamping plate 121 moves upward, it will pass through the cover 21 and contact the clamping column 122. When the clamping plate 121 moves upward to contact the conical surface of the clamping column 122, when the clamping plate 121 continues to move upward, it will squeeze the clamping column 122 to move forward through the conical surface, and the second elastic member 123 is compressed until the jack on the clamping plate 121 moves to align with the clamping column 122. At this time, under the action of the second elastic member 123, the clamping column 122 resets and is stuck at the jack, thereby fixing the clamping plate 121 and the floating frame 101. After all the sewage in the chamber is treated and discharged, just pull the clamping column 122 to disengage from the jack. In this way, it can be avoided that the floating frame 101 moves downward and causes the sealing plate 113 to rotate when the sewage is not completely discharged.

[0048] As Figure 9As shown in the figure, it further includes a stirring rod 131 and a servo motor 132. The servo motor 132 is installed on the right side outside the processing box body 1. The output shaft of the servo motor 132 passes through the processing box body 1 and is connected to the stirring rod 131. The stirring rod 131 is located in the three chambers on the right side, and the left side of the stirring rod 131 is rotatably connected to the leftmost partition plate 2.

[0049] After adding the medicament into the chamber to react with the sewage, the operation of the servo motor 132 can be controlled to drive the stirring rod 131 to rotate. When the stirring rod 131 rotates, it can stir the sewage and the medicament in the chamber, so that the sewage and the medicament can react better.

[0050] As Figure 10 shown in the figure, it further includes a lifting mechanism. The lifting mechanism includes a guide sleeve 141, a connecting rope 142, a pull rod 143 and a floating block 144. The guide sleeve 141 is connected to the front side of the right cover 21. The pull rod 143 is slidably connected in the guide sleeve 141. A connecting rope 142 is connected between the top of the pull rod 143 and the front side of the clamping column 122. A part of the connecting rope 142 is located in the guide sleeve 141, so that the guide sleeve 141 can guide the connecting rope 142. The bottom of the pull rod 143 is connected to the floating block 144.

[0051] When there is sewage in the rightmost chamber, the sewage will drive the floating block 144 to float. At this time, the floating block 144 will not pull the clamping column 122. After all the sewage is discharged, the floating block 144 sinks and pulls the pull rod 143 to move downward. The downward movement of the pull rod 143 pulls the clamping column 122 to move forward through the connecting rope 142. In this way, after the sewage is discharged, the clamping column 122 can be automatically pulled to move forward and separated from the clamping plate 121, without manual operation of moving the clamping column 122, and the operation is more convenient.

[0052] This embodiment also provides a method for electro-oxidation treatment of sodium phenoxide sewage, and the specific steps are as follows:

[0053] S1: Add sodium hydroxide, coagulant and flocculant into the three feeding cylinders 81 from right to left respectively. The medicament in the feeding cylinder 81 enters the injection groove through the discharge port;

[0054] S2: Connect the pipeline of the sodium phenoxide sewage to the liquid inlet pipe 7, and the sodium phenoxide sewage will enter the rightmost chamber through the liquid inlet pipe 7;

[0055] S3: Pull the right connecting rod 86 forward, the first elastic member 87 is compressed. When the connecting rod 86 moves forward, it drives the connecting rack 88 to move forward. The forward movement of the connecting rack 88 drives the first gear ring 84 to rotate. The rotation of the first gear ring 84 drives the feeding block 83 to rotate until the connecting rack 88 moves away from the first gear ring 84, and the feeding block 83 rotates 180 degrees. The medicament in the feeding block 83 will be added into the chamber, achieving the effect of adding the medicament;

[0056] S4: After the medicament is added into the chamber, it reacts with the sewage in the chamber. After the reaction, the liquid extraction pump 31 is controlled to operate, and the sewage is sent into the next chamber through the connecting pipe 32. Then, according to the above operation, the connecting rod 86 is pulled to move for the addition of the medicament. Repeating this way, after passing through the three chambers on the right, the sewage reacts with sodium hydroxide, coagulant and flocculant in sequence, causing the internal oil impurities to form flocs;

[0057] S5: When the liquid extraction pump 31 on the left operates, it can transport the sewage and flocs to above the material guiding frame 5 through the connecting pipe 32. The flocs are blocked by the filter screen 6, and the sewage passes through the filter screen 6 and enters the leftmost chamber;

[0058] S6: Connect the power supply to the connecting wire 43 to make the conductive plate 42 discharge, decompose the refractory organic matters remaining in the mineralization of the sewage to purify the water quality, make the sewage reach the discharge standard, open the valve at the drainage port to discharge the purified water, and complete the treatment of the sodium phenolate sewage.

[0059] The above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention.
