Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, in particular to a high-efficiency oil-water separation filtering device. Background Art

[0002] In urban life and industry, a large amount of oil and water are discharged. In order to protect the environment, the discharged oil and water need to be separated and filtered. Oil-water separation is mainly based on the density difference or chemical properties of water and oil, and uses the principle of gravity sedimentation or other physical and chemical reactions to remove impurities or complete the separation of oil and water. Therefore, corresponding separation and filtration devices are used.

[0003] When using the device to separate oil and water, it does not have the function of accurately stratifying the oil and water. Therefore, when stratifying the oil and water, the oil and water cannot be completely separated, and the filtered oil and water need to be filtered twice, which reduces the filtration efficiency. For this reason, we provide a high-efficiency oil-water separation filter device to solve the above problems. Utility Model Content

[0006] The utility model is a high-efficiency oil-water separation and filtering device, comprising a tank body; a coalescing filter element and a separation filter element are arranged inside the tank body, and the coalescing filter element and the separation filter element are arranged symmetrically, a coalescing filter seat fixedly connected to the inner wall of the tank body is fixed at the bottom of the coalescing filter element, a separation filter seat fixedly connected to the inner wall of the tank body is fixed at the bottom of the separation filter element, an outlet pipe penetrating the bottom position of the tank body is fixed at the bottom of the separation filter seat, an inlet pipe penetrating the bottom position of the tank body is fixed at the bottom of the coalescing filter seat, and a drainage pipe connected to the interior of the tank body is fixed at the bottom of the tank body.

[0008] The utility model is further configured that the upper end surface of the tank body is provided with a tank cover, and the lower end surface of the tank cover is fixed with a flange 2 abutting against the flange 1.

[0011] The utility model is further configured that a support foot is fixed on the surface side of the lower part of the tank body, and a liquid level meter connected with the interior of the tank body is fixed on the bottom of the tank body.

Since the density of the oil and water is inconsistent, the water will settle at the bottom of the tank body 1, while the oil is on the water surface. When the oil exceeds the bottom surface of the separation filter element 4, the oil at this time will penetrate into the separation filter element 4, and then the oil will flow out from the position of the outlet pipe 601, thereby realizing efficient separation treatment of the oil and water.
