Description

TECHNICAL FIELD

[0001] The present application relates to the field of sewage treatment, in particular to a silane coupling agent production wastewater recycling treatment device and method. BACKGROUND

[0002] As an important fine chemical, silane coupling agent has been widely used in the fields of building materials, energy and power, electronics, new energy vehicles, and metal ore dressing. The wastewater produced in the production process of silane coupling agent contains various pollutants, including unreacted silane compounds (such as silanol, siloxane, etc.), organic solvents (such as methanol, ethanol, acetic acid, etc.), heavy metal ions (such as chromium, nickel, lead, etc.), and oil substances. These pollutants have different physical and chemical properties, among which unreacted silane compounds have high biological toxicity and are difficult to degrade, and heavy metal ions can cause cumulative pollution to the environment.

[0003] At present, the main methods for treating silane coupling agent production wastewater include pretreatment, chemical oxidation, biological treatment, advanced treatment by physical and chemical methods, and resource recovery. In the pretreatment stage, large suspended solids are removed by a grid pool, and then the suspended solids and colloidal substances are coagulated into larger particles in the conditioning pool after coagulation and sedimentation, and a gas flotation device is used for separation. For example, the Chinese patent with publication number CN117945493B sets up a movable sleeve to make the bubbles in the conduit evenly disperse in the gas flotation cavity, accelerates the separation effect of waste residue and wastewater, and thus improves the purification efficiency. And through subsequent chemical oxidation treatment, biological treatment and other steps, the wastewater meets the discharge standard.

[0004] Because the types of suspended solids in silane coupling agent production wastewater are various and the densities are different, such as silane particles, emulsified oil, silane compounds, long-chain alcohols, etc., and the states of the flocculants formed after treatment of suspended solids with different densities are different, the flocculants formed by suspended solids with smaller density are loose and large in volume, and the flocculants formed by suspended solids with larger density are tight and small in volume. The bubbles generated by the traditional gas flotation device are too large to easily disperse the loose flocculants, and the bubbles are too small to easily reduce the floating speed of the flocculants, and the separation effect of the gas flotation device on suspended solids with different densities is poor. The subsequent treatment and separation of suspended solids are difficult, which is not conducive to the recycling of suspended solids and may cause harm to the environment. SUMMARY

[0005] In order to improve the poor separation effect of the gas flotation device on suspended solids with different densities in the prior art, which leads to difficult subsequent treatment, the present application provides a silane coupling agent production wastewater recycling treatment device and method.

[0006] The silane coupling agent production wastewater recycling treatment device provided by the present application adopts the following technical scheme: The application discloses a silane coupling agent production wastewater recycling treatment device, which comprises a pool body, the pool body comprises a grid pool and a slag scraping pool, a water inlet is formed in the grid pool, a water outlet is formed in the slag scraping pool, a detector for analyzing the components of wastewater is arranged in the grid pool, a comprehensive treatment pool is arranged between the grid pool and the slag scraping pool, and an air flotation assembly for treating wastewater is arranged in the comprehensive treatment pool. The air flotation assembly comprises a spiral frame arranged in the comprehensive treatment pool, an air flotation pipe is arranged in the spiral frame, a plurality of air injection heads are uniformly and spacedly arranged on the air flotation pipe, a pressure dissolved air tank is arranged on the side wall of the pool body, and the pressure dissolved air tank is connected with the air flotation pipe. A dosing assembly for feeding medicaments into wastewater is arranged on the comprehensive treatment pool, the dosing assembly comprises a medicament box arranged on the comprehensive treatment pool. An adjusting assembly for adjusting the opening size of the air injection head is arranged on the spiral frame, and a slag scraping assembly for scraping flocculation is arranged on the slag scraping pool.

[0007] According to the above technical scheme, because the densities of suspended matters in silane wastewater are different, after the medicaments are fed, the suspended matters with different densities form flocculation with different volumes, when the bubble diameter is close to the particle size of the flocculation, the adhesion effect is the highest, the floating speed of the flocculation can be improved, when the bubble is too large, the loose flocculation is easily dispersed, and when the bubble is too small, the floating speed of the flocculation is small; meanwhile, because the bubble size has a certain influence on the mixing effect of the medicaments, the smaller the bubble diameter is, the larger the specific surface area is, and the mixing effect of the medicaments is better, so the amount of the medicaments can be reduced.

[0008] When the silane coupling agent production wastewater is introduced into the grid pool, the grid in the grid pool screens out larger impurities, the detector in the grid pool analyzes the types and proportions of the suspended matters in the silane wastewater, the medicament box feeds the medicaments into the comprehensive treatment pool through a medicament injection pipe, the medicament box controls the medicament feeding amount according to the data of the detector, and the medicament feeding amount is matched with the content of the suspended matters in the wastewater; when the wastewater is introduced into the comprehensive treatment pool, the medicament box uniformly disperses the medicaments into the comprehensive treatment pool, the mixing effect of the medicaments and the wastewater is effectively improved, and the interference on the loose flocculation is reduced.

[0009] The pressure gas dissolving tank passes gas into the air float pipe, and forms bubbles through the air jet head arranged on the air float pipe. The adjusting assembly adjusts the opening size of the air jet head on the air float pipe, so that the size of the bubbles is distributed from small to large along the bottom to the top of the comprehensive treatment tank. The air jet head generates small bubbles first. The small bubbles are adsorbed on small flocculation bodies, the small flocculation bodies quickly float to the water surface and flow into the slag scraping tank. The small bubbles are adsorbed on large flocculation bodies. Since the adsorption effect is poor and the bubble diameter is small, the large flocculation bodies float slowly. When the large flocculation bodies float to a certain height, they are adsorbed by slightly larger bubbles generated by the air jet head. The slightly larger bubbles are adsorbed on the large flocculation bodies, so that the large flocculation bodies float to the water surface and flow into the slag scraping tank. The slag scraping assembly arranged on the slag scraping tank separates and recovers flocculation bodies of different volumes. Since the bubbles at the bottom of the comprehensive treatment tank are small, it is difficult for the small bubbles to make the precipitates float, thereby effectively accelerating the separation of the precipitates and the flocculation bodies in the wastewater. At the same time, the bubbles of different diameters make the flocculation bodies of different volumes have different floating speeds, so that the small flocculation bodies float to the water surface first, and the large flocculation bodies float to the water surface later, thereby separating the flocculation bodies of different volumes, improving the separation effect of the device, effectively improving the water quality of the treated wastewater, and reducing the harm to the environment.

[0038] The air floatation device in the prior art uses bubbles of uniform size to adsorb and float flocculation, but flocculation bodies of different densities have different sizes, and the adsorption effect of bubbles of different sizes on flocculation bodies of different sizes is different. Larger bubbles are easy to damage flocculation bodies of larger size and loose structure, and smaller bubbles have a slower floating speed on flocculation bodies, and the specific surface area of small bubbles is larger, which can improve the reaction effect of reagents on suspended solids in wastewater, correspondingly reduce the amount of reagents, save the amount of reagents, and reduce the difficulty of subsequent recovery and treatment of excess reagents in wastewater. For example, the silane coupling agent production wastewater contains heavy metal ions and organic matter, and the flocculation bodies formed by the heavy metal ions have a diameter of 100-500 μm.

The flocculation bodies formed by the organic matter have a diameter of 10-100 μm, and the micro-bubbles with a diameter of 45-60 μm have a poor floating effect on the flocculation bodies formed by the organic matter. The micro-bubbles with a diameter of 20-50 μm have a better adsorption effect on the flocculation bodies formed by the organic matter, but the micro-bubbles with a diameter of 20-50 μm have a poor floating effect on the heavy metal ions, such as the hydrolysis product of the silane coupling agent.

[0039] The detector 112 in the grid pool 11 detects the density and content of the wastewater, and adjusts the amount of reagents in the reagent tank 31 through the controller.

The vertical groove 3711 on the driving pipe 371 abuts against the connecting pipe 33, so that the spray head 34 on the connecting pipe 33 descends along the spiral frame 21. The reagents in the reagent tank 31 are introduced into the nozzle 35 through the spray pipe 36, and the nozzle 35 uniformly sprays the reagents in the comprehensive treatment pool 13 along the spiral frame 21. Compared with the prior art in which a stirring device is used to stir the reagents and wastewater, the device fully mixes the reagents and wastewater through the cooperation of the propeller and the spray head 34, reduces the interference of the stirring device on the flocculation bodies, and is beneficial to the rapid aggregation of the flocculation bodies.

[0040] When the connecting pipe 33 moves to the bottom of the comprehensive treatment pool 13, the position is the initial position of the connecting pipe 33. Before the connecting pipe 33 reaches the initial position, the pressure dissolved air tank 24 is not opened, and the air floatation pipe 22 does not generate bubbles. After the connecting pipe 33 reaches the initial position, the controller starts the pressure dissolved air tank 24 to aerate the air floatation pipe 22. At this time, the air outlet of the air jet head 23 on the air floatation pipe 22 is smallest, and the diameter of the generated bubbles is smallest.

[0041] The adjusting assembly 4 adjusts the opening size of the air jet head 23 and matches the opening size of the air jet head 23 with the height of the connecting pipe 33 on the threaded rod 32 during the upward movement of the connecting pipe 33 from the bottom of the comprehensive treatment tank 13, so that the air bubbles generated by the air jet head 23 farther away from the bottom of the comprehensive treatment tank 13 are larger; if the connecting pipe 33 does not reach the initial position, the air float pipe 22 is aerated, the reaction time of the medicament and the wastewater is shorter, and the suspended matter in the wastewater has not formed stable flocculating bodies, and if the top of the comprehensive treatment tank 13 is taken as the initial position, the large air bubbles generated are easy to disperse the loose and large flocculating bodies just formed.

[0042] During the upward movement of the connecting pipe 33 from the initial position, the small air bubbles generated by the air jet head 23 first adhere to the flocculating bodies with small volumes and make the flocculating bodies with small volumes quickly float to the water surface and flow to the slag removal tank 12, and due to the different sizes of the air bubbles generated by the air jet heads 23 at different heights, when the small air bubbles at the bottom of the comprehensive treatment tank 13 adhere to the flocculating bodies with large volumes, the flocculating bodies with large volumes float slowly, and after the flocculating bodies with large volumes float to a certain height, the slightly larger air bubbles continue to adhere to the flocculating bodies with large volumes and drive the flocculating bodies with large volumes to further float, until the flocculating bodies float to the water surface and flow to the slag removal tank 12; the device separates the flocculating bodies with different volumes by setting different sizes of air bubbles at different heights, effectively improves the separation of suspended matters with different densities, thereby reducing the difficulty of subsequent treatment of different suspended matters, effectively improves the effluent water quality of the wastewater, and reduces the harm of harmful substances in the wastewater to the environment.

The adjusting blocks 42 and the moving plate 44 are both provided with adjusting holes 421, and when the adjusting holes 421 are concentric with the air jet heads 23, the air bubbles generated by the air jet heads 23 are the largest. The electric push rod 45 is electrically connected with the detector 112, and the cable connected to the electric push rod 45 is connected with the external power supply device through the inside of the spiral frame 21. The adjusting assembly 4 further comprises a synchronizing member for driving the wedge-shaped block 41 to move and a resetting member 46 for resetting the adjusting blocks 42.

[0046] Since the wastewater contains various kinds of suspended solids, different kinds of suspended solids have different densities, for example, the density ranges of two kinds of suspended solids are 0.9-1.05 g / cm³ and 0.95-1.1 g / cm³ respectively, the intersection of the density ranges of the two kinds of suspended solids is 0.95-1.05 g / cm³, the air flotation assembly 2 generates bubbles of a corresponding size for the suspended solids with a density range of 0.95-1.05 g / cm³, and takes 1 g / cm³ as a boundary, and separates the suspended solids by controlling the size of the bubbles, the device can effectively separate suspended solids with different densities, but at the same time, the processing efficiency of the suspended solids outside the density range will be reduced.

[0049] When the connecting pipe 33 rotates, the wedge-shaped block 41 on the medicine spraying head 34 abuts against the adjusting block 42 on the spiral frame 21, the wedge-shaped block 41 pushes the adjusting block 42 to move in the spiral frame 21, the protrusions on the moving plate 44 fix the adjusting block 42, the adjusting hole 421 on the adjusting block 42 is dislocated from the air jet head 23, so as to adjust the opening size of the air jet head 23, so that the air jet head 23 close to the top of the comprehensive treatment tank 13 generates larger bubbles.

[0050] When the density and content of the suspended matter change, the air jet head 23 needs to generate bubbles with a size suitable for the density and content of the suspended matter; the electric push rod 45 is started, the electric push rod 45 drives the moving plate 44 to move, and the adjusting hole 421 on the moving plate 44 is dislocated from the air jet head 23, so as to adjust the opening size of the air jet head 23, so as to change the size range of the bubbles generated by the air jet head 23, and make the bubble size suitable for the suspended matter.
