Embodiment 1

[0030] Such as figure 1 As shown, a filter module for oil-water separation includes a filter element. The filter element is a cylindrical structure. It has a cavity, and 4 drain pipes are arranged in the cavity. The upper ends of the 4 drain pipes extend out of the cavity and reach above the filter element. It is an organic lipophilic and hydrophobic material filter layer. A channel for oil and water to be treated to circulate is provided between the shell layer 3 and the first filter layer 1. Mesh plates 7 for oil and water to enter are provided at both upper and lower ends of the channel.

Embodiment 2

[0032] A filter residue screen is also arranged on the inner wall of the mesh plate 7 .

[0033] The first filter layer 1 is a PP layer, a polyurethane layer, and a graphene-based oil-absorbing layer. The materials described below are all existing materials.

[0034] The graphene-based oil-absorbing layer is one of a modified graphene layer, a graphene-based carbon sponge layer, a graphene-based nickel foam layer, and a graphene-based porous ceramic layer. Among them, the graphene-based carbon sponge layer has good elasticity and oil absorption capacity. Because of its elasticity, the absorbed oil can be pressed out or sucked out for recycling.

[0035] A second filter layer 6 is sheathed outside the first filter layer 1, and the second filter layer 6 is a filter layer of inorganic lipophilic and hydrophobic materials.

[0036] The second filter layer 6 is an activated carbon layer, a clay layer, a zeolite layer, and a silicon dioxide layer.

Embodiment 3

[0038] Similar to Embodiment 1, the shell layer 3 has a cavity structure and a plurality of branch holes 8 are uniformly arranged on the inner wall surface of the shell layer 3 , and the plurality of branch holes 8 communicate with the cavity structure of the shell layer 3 . In practice, when oil and water are separated, grease is easy to condense, which is not conducive to adsorption and recovery. In order to solve this problem, the shell layer 3 is set in a cavity structure and the inner wall surface of the shell layer 3 is evenly provided with a plurality of branch holes 8. Through Water vapor is introduced into the shell layer 3, so that the water vapor overflows from multiple branch holes 8, and the oil-water mixture increases the temperature of the oil-water, preventing the oil from coagulating. In addition, the increase of the oil-water temperature can also reduce the degree of emulsification of the emulsified oil, which solves the problem of The problem of oil-water sep...

Abstract

The invention discloses an oil-water separation filter module which comprises a filter core, wherein the filter core is of a barrel-shaped structure; the filter core is sequentially in sleeve connection with an inner shell layer, a first filter layer and an outer shell layer from inside to outside; the inner shell body comprises a cavity, a liquid draining pipeline is arranged in the cavity, the upper end of the liquid draining pipeline extends out of the cavity and extends above the filter core, the upper end of the liquid draining pipeline is connected with an oil pump, the first filter layer is an organic oleophylic hydrophobic material filter layer, a channel for oil water to be treated to flow is arranged between the outer shell layer and the first filter layer, and net-shaped platesfor the oil water to enter the channel are arranged at the upper end and the lower end of the channel. The oil-water separation filter module disclosed by the invention has the advantages of ingeniousand reasonable structure arrangement and ability in effectively improving oil-water separation quality and purity.

Description

technical field [0001] The invention relates to the field of oil-water separation, in particular to an oil-water separation module, an oil-water separation system and a method. Background technique [0002] In recent years, the exploitation and utilization of oil, industrial production and domestic waste will inevitably bring a series of serious pollution problems to the water environment, and the water body is polluted. At present, less than half of the total discharge of industrial and urban sewage in my country has undergone centralized treatment, and most of the rest are directly discharged into rivers, resulting in the deterioration of a large number of water resources. The severe situation of high cost and low efficiency of water treatment has caused a large number of small and medium-sized enterprises to take risks and discharge sewage directly, and the problem of water resource pollution is hard to return. The research, development and large-scale application of new...
