Description

Technical Field

[0001] This utility model relates to a high-efficiency induced coalescence oil removal device, belonging to the field of chemical equipment technology. Background Technology

[0002] Induced coalescence oil removal devices are physical equipment that uses the principle of "coalescing" to separate oil and water. The core of this process involves using a special "coalescing material" (usually a hydrophobic and oleophilic medium) to induce tiny oil droplets in the wastewater to collide and merge, coalescing into larger droplets. These larger droplets then utilize the density difference (oil is lighter than water) to achieve rapid flotation and separation. However, during the separation process, turbulence can easily occur in the oil-water mixture during transport, affecting the separation efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a highly efficient induced coalescence oil removal device to solve the problems mentioned in the background art.

[0006] Preferably, the flow stabilizing pressure plate consists of an mounting sleeve, a steering knuckle, an inclined pressure plate, a glass guide plate, a triangular horizontal mounting block, a steering linkage, a float, and a horizontal cross plate.

Detailed Implementation

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] like Figures 1-4 As shown, a high-efficiency induced coalescence oil removal device includes an inlet 1, a one-way valve 2, an air inlet 3, a coalescence corrugated plate 4, an oil collection weir pipe 5, an outlet 6, a flow stabilizing plate 7, and a separation box 16. The inlet 1 pipeline is installed on the left side of the separation box 16 to position the one-way valve 2 and the air inlet 3. The coalescence corrugated plate 4 is installed at the lower end of the center position of the separation box 16. The oil collection weir pipe 5 is connected and installed at the upper right end of the coalescence corrugated plate 4. The outlet 6 is installed on the right side of the separation box 16. The flow stabilizing plate 7 is positioned at the lower end of the inlet 1 pipeline.

[0013] The water inlet 1 water inlet pipe is equipped with an air inlet pipe at a 30-degree angle to the water flow direction. This pipe is equipped with a one-way valve to prevent water backflow. During the process of water flowing into the equipment, a slight negative pressure is formed in the narrow air inlet pipe, which draws in air. The air reaches the bottom of the equipment through the pipe and is released to form bubbles. The bubbles encapsulate oil particles in the water, helping the oil droplets in the water to float to the surface.

[0014] The flow stabilizing pressure plate 7 consists of an mounting sleeve 8, a steering knuckle 9, an inclined pressure plate 10, a glass guide plate 11, a triangular horizontal mounting block 12, a steering linkage 13, a float 14, and a horizontal plate 15. The mounting sleeve 8 is positioned and installed with the inclined pressure plate 10 via the steering knuckle 9. The glass guide plate 11 is installed at the lower end of the inclined pressure plate 10. The triangular horizontal mounting block 12 is fixed to the inclined pressure plate 10 with screws. The triangular horizontal mounting block 12 is positioned and installed with the float 14 via the steering linkage 13. The float 14 is horizontally mounted with the horizontal plate 15 in the left-right direction. The design of the steering knuckle 9 enables the inclined pressure plate 10 to swing up and down. The smooth surface and low friction coefficient of the glass guide plate 11 enable the stable movement of the oil-water mixture towards the coalescing corrugated plate 4 at an inclined angle. The floating traction of the float 14 ensures the stability of the inclined pressure plate. The design and installation of the horizontal plate 15 improves the floating stability of the float 14 and ensures the stability of the flow guidance.

[0015] The corrugated coalescing plate 4 has a corrugation depth of 5-8 mm, a wavelength of 10-15 mm, and a surface micro-pit density of 200-500 pits / cm². It includes at least three levels of corrugated coalescing plates with tilt angles of 15°-30°, and the plate surface has honeycomb-shaped micro-pits and a hydrophobic and oleophilic coating.

[0016] Specific usage: A high-efficiency induced coalescence oil removal device. Oily wastewater enters the bottom of the device through the inlet. Due to the flow velocity of the water, negative pressure is generated at the air inlet, drawing in air. A one-way valve prevents backflow caused by changes in water pressure and volume. Air bubbles are formed at the bottom of the device, helping oil particles in the water to float. The inclined pressure plate of the flow stabilizing plate, together with the float and horizontal plate, guides the water flow. The oil-water mixture passes through the coalescence corrugated plate to separate the oil and water. Based on the difference in material density, the oil is discharged through the oil collection weir pipe on the top, while the water flows from the bottom into the buffer tank and is finally discharged through the outlet. Bubbles are generated by self-absorbing air. The flow channel of the induced oil removal and coalescence module has an asymmetrical structure that is wider at the top and narrower at the bottom. The cross-sectional area of ​​the upper flow channel is 30%-50% larger than that of the lower one. In the asymmetrical flow channel, the oil droplets undergo acceleration and deceleration flow, inducing collision and coalescence of oil droplets. The microstructure surface captures submicron oil droplets and coalesces and grows. The oil phase achieves autonomous floating and separation in the gravity separation chamber. The design and installation of the steering knuckle of the flow stabilizer plate enables the inclined pressure plate to swing up and down. The smooth surface of the glass guide plate and the low coefficient of friction enable the oil-water mixture to move stably towards the coalescing corrugated plate at an angle. The floating pontoon traction inclined pressure plate ensures the stability of the inclined pressure plate. The design and installation of the horizontal plate improves the floating stability of the pontoon and ensures the stability of the flow guide.

[0017] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
