Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a demulsification device for treating wastewater in a factory. Background Technology

[0002] During factory production, a large amount of wastewater containing emulsions is generated. Emulsions are stable dispersion systems composed of oil, water, and surfactants, among other things. Their stable structure makes it difficult to effectively separate oil and water using conventional solid-liquid separation methods. Directly discharging wastewater containing emulsions not only wastes water resources but also causes serious environmental pollution.

[0003] Chinese patent application CN221459990U discloses a demulsification treatment device for oily wastewater. This patent application solves the problem that the amount of demulsifier added is not fixed and is mostly controlled manually. Moreover, the demulsifier is added directly from above, which makes it easy for it to float on the oil layer, thus affecting the mixing efficiency between the demulsifier and the material, and even causing incomplete mixing, which affects the quality of the material after demulsification. However, the above patent still has the following shortcomings:

[0004] (1) When demulsifier is added, high-viscosity demulsifier is prone to forming a "wall-hanging layer" on the pipe wall, which leads to a reduction in the effective flow area of ​​the pipe or even blockage;

[0005] (2) After the demulsifier is added to the sewage, it is difficult to mix and contact with the sewage quickly, so that the demulsifier can fully react with the sewage, which affects the demulsification effect;

[0006] (3) Because the stable structure of the emulsion is difficult to completely destroy, the surface of the oil droplets is always coated with surfactants, which makes it difficult for the oil droplets to aggregate after collision and they remain dispersed in the water in a small particle size state. According to Stokes' law, the smaller the oil droplet size, the greater the resistance during the floating process and the slower the floating speed. This makes the oil-water separation efficiency low and the demulsification time significantly prolonged.

[0007] To address this issue, we propose a demulsification device for wastewater treatment in factories. Summary of the Invention

[0018] Beneficial effects

[0019] This invention provides a demulsification device for treating wastewater in factories. Compared with the prior art, it has the following advantages:

[0020] Beneficial effects:

[0021] (1) By setting up an impact vibration mechanism, the impact rod is used to circulate and impact the feed pipe, causing the feed pipe to vibrate, thereby allowing the demulsifier in the feed pipe to be discharged quickly, avoiding the demulsifier from adhering to the pipe wall due to high viscosity and forming a "wall-hanging layer", increasing the effective flow area of ​​the pipeline and effectively preventing blockage.

[0022] (2) By setting up the agent dispersing component, when the impact vibration mechanism is working, the horizontal reciprocating movement of the impact rod drives the rotating paddle to rotate in both directions, which quickly disperses the demulsifier discharged from the feed pipe, allowing it to quickly integrate into the sewage and fully react with the sewage. Compared with the traditional stirring method, the demulsifier can flow irregularly in the sewage through the forward and reverse circulation and rotation, which significantly shortens the reaction start-up time and improves the demulsification efficiency and effect.

[0023] (3) By setting up the horizontally moving intermittently rotating component, it is linked with the impact vibration mechanism. When the vertical plate moves horizontally, it can synchronously drive the rotating plate to move horizontally periodically and rotate 90 degrees. The movement and rotation of the rotating plate will generate shear force along the direction of water flow. The combined motion of the rotating plate will cause the emulsion to form turbulent vortex. The oil droplets collide frequently in the turbulence. After the shear force destroys the stable structure of the emulsion, the exposed oil droplet surface is more likely to agglomerate into larger oil droplets through collision. At the same time, the centrifugal force generated by the rotation will exert a radial force on the oil droplets, causing them to break away from the original stable suspension state and accelerate their upward movement.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention provides three technical solutions, specifically including the following embodiments:

[0036] Example 1

[0037] Please see Figures 1-5 A demulsification device for treating wastewater in a factory includes a demulsification cylinder 1, which is conical in shape. The top of the demulsification cylinder 1 is connected to a feed pipe 2, the bottom of which extends into the interior of the demulsification cylinder 1. The top of the feed pipe 2 is connected to a hopper 5, into which a demulsifier is poured. The demulsifier then enters the demulsification cylinder 1 through the feed pipe 2 to react with the wastewater. The demulsifier is specifically PAMAM dendritic molecular demulsifier, which has viscosity. PAMAM dendritic molecular demulsifier exhibits a dendritic branch structure. This unique structure gives it high surface activity, enabling it to be efficiently adsorbed at the oil-water interface, destroying the interfacial film of the stable emulsion system, breaking the emulsion state between oil and water, and promoting the coalescence and separation of oil droplets, thereby achieving the demulsification treatment of wastewater. The demulsification cylinder 1 is equipped with an impact vibration mechanism 3 that vibrates the feed pipe 2 to accelerate the feeding.

[0038] The impact vibration mechanism 3 includes a base 31 fixed to the top of the demulsifying cylinder 1. A first groove 32 is provided on the top of the base 31, and a slide block 33 is slidably connected inside the first groove 32. A second groove 34 is provided on the top of the slide block 33. The first groove 32 and the second groove 34 are specifically dovetail grooves. The dovetail grooves prevent the slide block 33 and the movable seat 35 from falling off during sliding. The movable seat 35 is slidably connected inside the second groove 34. A horizontal bar 36 is fixed to one side of the movable seat 35, and a vertical plate 37 is fixed to one end of the horizontal bar 36. An impact rod 38 is fixed to one side of the vertical plate 37. A horizontal groove 39 is provided through the top of the demulsifying cylinder 1, and the vertical plate 37 slides inside the horizontal groove 39. The horizontal groove 39 provides space for the horizontal movement of the vertical plate 37, and the dimensions of the vertical plate 37 and the horizontal groove 39 are compatible. A side plate 310 is fixed to one side of the base 31, and a fixing rod 311 is fixed to one side of the side plate 310. A rotating plate 312 is rotatably connected to the outer surface of the fixed rod 311 via a pin. A square plate 313 is fixed to the bottom of the rotating plate 312, and a square plate 314 is fixed to the top of the movable seat 35. A small inclined surface is provided on one side of the square plate 313 and one side of the square plate 314. When the two inclined surfaces are in contact, the rotating plate 312 can be raised. A trapezoidal block 315 is fixed to the top of the slide seat 33, and a connecting rod 316 is fixed to the other side of the movable seat 35. One end of the connecting rod 316 passes through the trapezoidal block 315 and extends to the outside of the trapezoidal block 315. The outer surface of the connecting rod 316 is slidably connected to the inner surface of the trapezoidal block 315. A spring 317 is sleeved on the outer surface of the connecting rod 316. The spring 317 is configured to provide force to the impact rod 38. When the spring 317 is released, the impact rod 38 impacts to the right. A drive assembly 4 is provided on the base 31 and the slide seat 33 to drive the slide seat 33 to slide horizontally.

[0039] One end of spring 317 is fixed to one side of the movable seat 35, and the other end of spring 317 is fixed to one side of the trapezoidal block 315. The inclined surface of the rotating plate 312 contacts and presses against the inclined surface of the trapezoidal block 315. After the inclined surface of the rotating plate 312 contacts the inclined surface of the trapezoidal block 315, the rotating plate 312 can be raised.

[0040] The drive assembly 4 includes a rack 41 fixed to one side of the slide 33, a U-shaped plate 42 fixed to one side of the base 31, a gear 43 rotatably connected to one side of the base 31, the gear 43 meshing with the rack 41, and a motor 44 fixed to one side of the U-shaped plate 42. The motor 44 is a three-phase asynchronous motor that can rotate in both directions, is controlled by an external switch, and is electrically connected to an external power supply. The motor 44 drives the gear 43 to rotate.

[0041] By setting the impact vibration mechanism 3, the impact rod 38 is used to circulate and impact the feed pipe 2, causing the feed pipe 2 to vibrate. This allows the demulsifier in the feed pipe 2 to be discharged quickly, preventing the demulsifier from adhering to the pipe wall due to its high viscosity and forming a "wall-hanging layer". This increases the effective flow area of ​​the pipeline and effectively prevents blockage.

[0042] One side of the demulsifying cylinder 1 is connected to a water inlet pipe 8, and the top of the water inlet pipe 8 is connected to a liquid hopper 9. Wastewater is poured into the liquid hopper 9 and then flows into the demulsifying cylinder 1 through the water inlet pipe 8. The other side of the demulsifying cylinder 1 is connected to an oil drain pipe 10, which is connected to the oil inlet of an external oil pump. After the external oil pump is started, the oil floating on the upper layer after demulsification can be extracted. The bottom of the demulsifying cylinder 1 is connected to a drain pipe 11, which is used to discharge the wastewater after demulsification. Valves 12 are installed on both the drain pipe 11 and the oil drain pipe 10. A viewing window 13 is installed on one side of the demulsifying cylinder 1. The viewing window 13 is made of glass material, and the viewing window 13 is set to observe the amount of wastewater added inside the demulsifying cylinder 1.

[0043] Example 2

[0044] Based on Example 1, see Figure 6 As shown, the demulsifier cylinder 1 is equipped with a material dispersing assembly 6 that rapidly disperses the demulsifier discharged from the feed pipe 2. The material dispersing assembly 6 includes a rotating rod 61 rotatably connected between the inner walls of the demulsifier cylinder 1. A rotating paddle 62 is fixed on the rotating rod 61. The rotating paddle 62 is located to the lower left of the feed pipe 2. Being close to the feed pipe 2 can better disperse the demulsifier. A gear 63 is fixed on the rotating rod 61. A rod seat 64 is fixed on the impact rod 38. A vertical rod 65 is fixed to the bottom of the rod seat 64. A support plate 66 is fixed to the bottom of the vertical rod 65. An installation rod 67 is fixed to the bottom of the support plate 66. A rack 68 is fixed to the bottom of the installation rod 67. The rack 68 meshes with the gear 63.

[0045] With the addition of the material dispersing component 6, when the impact vibration mechanism 3 is working, the horizontal reciprocating movement of the impact rod 38 drives the rotating paddle 62 to rotate in both directions, quickly dispersing the demulsifier discharged from the feed pipe 2 and allowing it to quickly integrate into the wastewater, fully contacting and reacting with the wastewater. Compared with the traditional stirring method, the forward and reverse rotation method allows the demulsifier to flow irregularly in the wastewater, significantly shortening the reaction start-up time and improving the demulsification efficiency and effect.

[0046] Example 3

[0047] Based on Example 2, see Figures 7-9As shown, the interior of the demulsifying cylinder 1 is equipped with a horizontally moving intermittent rotating assembly 7. The horizontally moving intermittent rotating assembly 7 is used to form turbulent flow between the emulsion and the sewage. The horizontally moving intermittent rotating assembly 7 includes a square rod 71 fixed to one side of the inner wall of the demulsifying cylinder 1. The square rod 71 is configured to provide support for the entire device. One end of the square rod 71 is fixed with a U-shaped seat 72. A slider 73 is slidably connected to the inner surface of the U-shaped seat 72. A rotating seat 74 is rotatably connected to the top of the slider 73.

[0048] Two wing plates 75 are fixed on the rotating base 74. A fixing block 76 is fixed on one side of the slider 73. A rotating block 77 is rotatably connected to the top of the fixing block 76. A connecting ear 78 is fixed on one side of the rotating base 74. A slide rod 79 is slidably connected to the inner surface of the rotating block 77. One end of the slide rod 79 is rotatably connected to the connecting ear 78 through a pin. A circular plate 710 is fixed on the slide rod 79. A second spring 711 is sleeved on the slide rod 79. One end of the second spring 711 is fixed to one side of the circular plate 710. The other end of the second spring 711 is fixed to one side of the rotating block 77. Two limiting posts 712 are fixed on the top of the slider 73. The setting of the limiting posts 712 can prevent the two wing plates 75 from rotating excessively, so that the two wing plates 75 rotate 90 degrees each time, avoiding excessive rotation angle, which would affect the reaction between the demulsifier and the sewage. Two connecting plates 713 are fixed on one side of the U-shaped base 72.

[0049] The tops of the two connecting plates 713 are fixed with columns 714. The purpose of the columns 714 is to change the angle of the two wing plates 75. Each time the column 714 is in contact, the two wing plates 75 can be rotated 90 degrees. The wing plates 75 are in contact and pressed with the columns 714. The top of the rotating seat 74 is fixed with a cylinder 715. The top of the cylinder 715 is fixed with a top plate 716. The bottom of the top plate 716 is fixed with a bottom rod 717. The bottom of the bottom rod 717 is fixed with a rotating plate 718. The rotating plate 718 is located in the sewage. The setting of the rotating plate 718 can generate shear force along the water flow direction. The combined motion of the rotating plate causes the emulsion to form a turbulent vortex. One side of the vertical plate 37 is fixed with an L-shaped plate 719. One side of the L-shaped plate 719 is fixed with one side of the slider 73.

[0050] By setting up the horizontally moving intermittently rotating component 7, which is linked with the impact vibration mechanism 3, the vertical plate 37 can synchronously drive the rotating plate 718 to perform periodic horizontal movement and 90-degree self-rotation when moving horizontally. The movement and rotation of the rotating plate 718 will generate shear force along the direction of water flow. The combined motion of the rotating plate 718 will cause the emulsion to form turbulent vortices. Oil droplets collide frequently in the turbulence. After the shear force destroys the stable structure of the emulsion, the exposed oil droplet surface is more likely to agglomerate into larger oil droplets through collision. At the same time, the centrifugal force generated by the rotation will exert a radial force on the oil droplets, causing them to break away from the original stable suspension state and accelerate their upward movement.

[0051] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0052] During operation, wastewater is poured into hopper 9 and enters demulsifying cylinder 1 through inlet pipe 8. The wastewater level is observed through sight window 13. When the required level is reached, wastewater addition is stopped. Demulsifier is poured into hopper 5 and then enters demulsifying cylinder 1 through feed pipe 2. Motor 44 is started, which drives gear 43 to rotate. Gear 43 drives rack 41 to move to the right, which in turn drives slide 33 to move to the right. Slide 33 then drives moving seat 35 to move to the right, causing square plate 313 to contact and press against square plate 314, thereby causing moving seat 35 to move to the right. The connecting rod 316 slides within the second chute 34 while simultaneously sliding within the trapezoidal block 315, compressing the first spring 317. The first spring 317 stores energy. When the inclined surface of the rotating plate 312 contacts and presses against the inclined surface of the trapezoidal block 315, the rotating plate 312 rotates and lifts, causing the first square plate 313 to separate from the second square plate 314. At this time, the movable seat 35, in a state of energy storage, drives the crossbar 36 and the impact rod 38 to impact to the right. The impact rod 38 acts on the feed pipe 2, causing it to vibrate. The high-viscosity demulsifier in the feed pipe 2 flows out more rapidly. The impact rod 38 is horizontal... During the movement, rack 68 moves synchronously, which in turn drives gear 63 to rotate in both directions. This, in turn, drives rotating rod 61 and rotating paddle 62 to rotate in both directions. When rotating paddle 62 rotates, it rapidly disperses the demulsifier discharged from feed pipe 2, allowing the demulsifier to quickly and fully integrate into the wastewater for demulsification. During the horizontal movement of vertical plate 37, slider 73 slides synchronously in U-shaped seat 72. When wing plate 75 contacts and presses against one of the columns 714, column 714 causes wing plate 75 and rotating seat 74 to rotate 90 degrees, thereby driving rotating plate. The 718 rotates 90 degrees synchronously. During the horizontal reciprocating movement, the 718 continuously moves horizontally and rotates 90 degrees intermittently. The 718 generates shear force during its movement. The combined motion of the 718 causes the emulsion to form turbulent vortices. Oil droplets collide frequently in the turbulence. After the shear force destroys the stable structure of the emulsion, the exposed oil droplet surface is more likely to agglomerate into larger droplets through collision. After demulsification is completed, the oil floats above the sewage. Open the valve 12 on the oil drain pipe 10 to discharge the sludge oil, and open the valve 12 on the drain pipe 11 to discharge the sewage.

[0053] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
