Description

Technical Field

[0001] This utility model belongs to the field of oil-water separation technology, specifically an oil-water separation device. Background Technology

[0002] Oil-water separation mainly relies on the density difference or chemical properties of water and oil, utilizing the principle of gravity sedimentation or other physicochemical reactions to remove impurities or separate oil and water. Known oil-water separation methods mainly include gravity separation, centrifugal separation, electrostatic separation, adsorption separation, and flotation separation, among which gravity separation is the most widely used.

[0003] Due to the different relative densities of oil, gas, and water, an oil-water mixture with a certain composition will form a specific ratio of oil, gas, and water phases when the system is in equilibrium under certain pressure and temperature. When the relatively lighter components are in a laminar flow state, the heavier component droplets settle according to the motion law of Stokes' law. Gravity sedimentation separation equipment is designed based on this basic principle. According to Stokes' law, the sedimentation velocity is directly proportional to the square of the radius of water in the oil, directly proportional to the density difference between oil and water, and inversely proportional to the viscosity of the oil. By increasing the density of water, widening the density difference between oil and water, and decreasing the viscosity of the oil, the sedimentation separation velocity can be increased, thereby improving the separation efficiency. In existing technologies, ordinary treatment equipment is mostly an integrated structure of a single sedimentation tank, which cannot add or remove treatment modules according to the actual processing capacity. Moreover, the feeding and discharging of ordinary treatment equipment is not convenient, especially the discharge end, which generally suffers from slow speed. Summary of the Invention

[0004] The first technical problem that this utility model aims to solve is that most ordinary treatment equipment is an integrated structure of a single sedimentation tank, which makes it impossible to add or remove treatment modules according to the actual treatment volume.

[0005] The second technical problem that this utility model aims to solve is that the feeding and discharging of materials in ordinary processing equipment is not convenient enough, especially at the discharge end, where it is generally slow.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0007] An oil-water separator includes a processing tank, an end cap, a U-shaped groove, a screw, a handle, an inner protruding ring, a filter screen fixing frame, an outer protruding ring, a pre-filtration zone, a post-filtration zone, an inlet pipe, a safety valve mounting position, an outlet pipe, a bypass pipe mounting position, and a valve. The screw is rotatably connected to the outside of the processing tank's port. The end cap has a U-shaped groove, which presses against the processing tank. The screw flips up and enters the U-shaped groove to be fixed with a nut. The handle is mounted on the end cap. An inner protruding ring is located inside the processing tank, and an outer protruding ring is located outside the filter screen fixing frame. The outer protruding ring and the inner protruding ring cooperate to fix the filter screen on the filter screen fixing frame. The filter screen fixing frame divides the inside of the treatment tank into a pre-filtration zone and a post-filtration zone. The filter screen is blocked between the pre-filtration zone and the post-filtration zone. The upper and lower sides of the treatment tank are respectively provided with an inlet pipe and an outlet pipe. A safety valve mounting position is provided on the side of the inlet pipe, and a safety valve is installed on the safety valve mounting position. A bypass pipe mounting position is provided on the side of the outlet pipe, and a bypass pipe is installed on the bypass pipe mounting position. Valves are provided on both the inlet pipe and the outlet pipe.

[0008] Preferably, there are multiple processing tanks, with the input pipes of the multiple processing tanks converging into a single input main pipe, and the output pipes of the multiple processing tanks converging into a single output main pipe.

[0009] Preferably, a valve is also provided on the bypass pipe.

[0010] Preferably, a pressure rod is fixed on the underside of the end cap, and when the end cap is fixed by screws, the pressure rod presses against the outer protruding ring.

[0011] Preferably, a sealing gasket is provided on the lower side of the end cap and the upper side of the inner protrusion ring.

[0012] Preferably, the treatment tank is a reducing pipe, with the inner diameter of the treatment tank gradually decreasing from top to bottom.

[0013] Preferably, an electric heating mantle is provided on the outside of the processing tank, and the power supply line of the electric heating mantle is connected to a power source.

[0014] Preferably, the bottom side of the filter fixing frame has mounting holes, and screws are provided on the base plate, with the screws fixed at the mounting holes.

[0015] This utility model discloses an oil-water separation device. This device employs a multi-tank assembly configuration, allowing for the addition or removal of processing units based on throughput. Furthermore, after sedimentation (utilizing natural gravity settling and relying on the density difference between oil and water for natural stratification), pressure can be increased from above the liquid via the input pipe, enhancing the water output rate. A filter screen located in the middle of the system effectively blocks large solid particles. Structurally, this utility model features a filter screen fixed to a filter screen frame, dividing the processing tank into a pre-filtration and post-filtration zone. The filter screen is positioned between these two zones. Input and output pipes are located on the upper and lower sides of the processing tank, respectively. A safety valve mounting position is located on the side of the input pipe, where a safety valve is installed. A bypass pipe mounting position is located on the side of the output pipe, where a bypass pipe is installed. Valves are also installed on both the input and output pipes. This utility model offers greater flexibility in adapting to process requirements and improves the water output rate.

[0016] In this invention, because the output pipes have a confluence structure, each output pipe can only output in a concentrated manner. To address this issue, bypass pipes are provided, allowing for separate outputs from each bypass pipe. Regarding the function of increasing the water output rate by pressurizing the liquid from above using the input pipe, if the system is in a closed state, pressurizing the system would lead to an increase in system pressure. However, in this invention, an output pipe is located at the bottom of the system. Therefore, when pressurizing the liquid from above using the input pipe, the output pipe acts as a pressure relief channel and will not cause the system pressure to rise; it will only promote water output.
