Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and more specifically to an apparatus for treating heavy oily wastewater. Background Technology

[0002] The main difference between heavy oil and other crude oils lies in its viscosity and density. Heavy oil contains fewer light fractions and has a higher content of gums and bitumen. Due to its high viscosity and poor fluidity, heavy oil requires the injection of high-temperature steam into the reservoir to enhance its fluidity. In addition to its high viscosity, heavy oil also has a high density. Light oil, or low-density crude oil, has a density below 880 kg / m³, typically around 840 kg / m³, while the average density of heavy oil is 900 kg / m³, and some extra-heavy oils have densities above 990 kg / m³. The density difference between oil and water in heavy oil spills is small, and the crude oil particles can sometimes remain suspended in water for extended periods.

[0003] The oil-water mixture extracted by surface pumping equipment is called produced fluid, and the wastewater obtained after oil-water separation is called heavy oil wastewater. Heavy oil wastewater contains more impurities, including not only its own gum and bituminous material but also a significant amount of mud and sand. Viscosity reducers are often added during development, further complicating the composition of heavy oil wastewater. The wastewater is also highly emulsified; the gum and bituminous material in heavy oil wastewater have natural emulsifying properties, easily forming oil-in-water emulsions centered around tiny oil droplets, making demulsification of heavy oil wastewater more difficult.

[0004] In the existing heavy oil wastewater treatment process, the first step is to pass the collected heavy oil wastewater into an electrochemical advanced catalytic oxidation device for oil-water separation. The second step is to introduce it into a coagulation sedimentation tank to remove viruses and bacteria, thus avoiding the disinfection process. The third step is to introduce it into a dual-filter media and adsorption column for purification.

[0005] In the above three-step processing steps, when purifying the material using dual-filter media and adsorption columns, the existing dual-filter media and adsorption device structure are difficult to replace quickly and clean afterwards, affecting the final purification efficiency and effect. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a device for treating heavy oily wastewater, which has a simple overall structure, is easy to operate, and can quickly replace its purification components and perform subsequent cleaning operations.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0008] An apparatus for treating heavy oily wastewater includes a main body, a protective side plate, a first purification structure, and a second purification structure fixedly connected to the surface of the main body. An outlet pipe is fixedly connected to the bottom of the second purification structure. A conveying pipe is fixedly connected between the first and second purification structures. Support seats are fixedly installed on the back of both the first and second purification structures, and these support seats are also fixedly connected to the surface of the main body. Each of the first and second purification structures includes a conveying box, a limiting cylinder, a filter cartridge, and a connecting joint. The limiting cylinder and the connecting joint are detachably connected. The filter cartridge and the limiting cylinder are fixedly connected. The limiting cylinder is also embedded inside the conveying box. A protective clamp is fixedly connected to the back of the limiting cylinder, and a fixing buckle is fixedly connected to the back of the protective clamp. A guide clamp is fixedly installed on the outside of the filter cartridge.

[0009] Furthermore, the main body of the device is vertically arranged in a "Z" shape, with an open front and protective side panels protruding along the top and bottom outer sides of the main body, forming a semi-enclosed arrangement for the first and second purification structures.

[0010] Furthermore, two sets of support bases are provided, located on the top and bottom surfaces of the front of the main body of the device.

[0011] Furthermore, the guide clamp is an arc-shaped plate located inside the conveyor box on one side, below the protective clamp, and the protective clamp is an arc-shaped plate that partially surrounds the limiting cylinder.

[0012] Furthermore, the fixing buckle is L-shaped and is fixedly connected to the protective clamp while its outer end is fixedly fastened to the surface of the main body of the device.

[0013] Furthermore, the limiting cylinder is vertically arranged in a cylindrical shape, and the filter cylinder is a honeycomb filter cylinder.

[0014] Furthermore, it also includes a method of using an apparatus for treating heavy oily wastewater, the method comprising the following steps:

[0015] S1, the first purification structure and the second purification structure are connected by a guide pipe and fixed by a support 6;

[0016] S2, the purification column containing dual filter media and the resin filter column are respectively embedded in the limiting cylinders of the first purification structure and the second purification structure, and the sewage is introduced through the connector in the first purification structure.

[0017] S3, the introduced wastewater is first filtered through the limiting cylinder and filter cylinder in the first purification structure, and then introduced through the guide pipe into the limiting cylinder and filter cylinder in the second purification structure for secondary filtration, and finally discharged through the guide pipe at the bottom of the second purification structure.

[0018] S4. After filtration is complete, tighten the connector and remove the purification column and resin filter column of the dual filter media from the limiting cylinder for cleaning or replacement.

[0019] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows:

[0020] This invention achieves both convenient operation of the purification structure and a protective enclosure effect through the open-set main body of the device and the protective side plates on the outer side. Two sets of support seats are set on the top and bottom surfaces of the front of the main body of the device, which provide support for the two sets of purification structures.

[0021] In this invention, after the wastewater is purified by the purification components in the first purification structure, it flows downward and is discharged through the filter cartridge. At this time, the guide clamps are used to guide the flow of wastewater, and the protective clamps are used to enhance the protection of the limiting cylinder.

[0022] This invention uses a fixing buckle to fix the purification structure and the main body of the device, a limiting cylinder to facilitate the limiting and fixing of external purification components, and a filter cartridge to facilitate the discharge of purified wastewater.

These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0031] See Figure 1-4 As shown, an apparatus for treating heavy oily wastewater includes a main body 1. A protective side plate 2, a first purification structure 3, and a second purification structure 4 are fixedly connected to the surface of the main body 1. An outlet pipe 5 is fixedly connected to the bottom end of the second purification structure 4. A guide pipe 9 is fixedly connected between the first purification structure 3 and the second purification structure 4. Support seats 6 are fixedly installed on the back of both the first purification structure 3 and the second purification structure 4, and the support seats 6 are also fixedly connected to the surface of the main body 1. Both the first purification structure 3 and the second purification structure 4 include a conveying box 7, a limiting cylinder 12, a filter cartridge 14, and a connecting joint 10. The limiting cylinder 12 and the connecting joint 10 are detachably connected. The filter cartridge 14 and the limiting cylinder 12 are fixedly connected. The limiting cylinder 12 is also embedded inside the conveying box 7. A protective clamp 11 is fixedly connected to the back of the limiting cylinder 12. A fixing buckle 13 is fixedly connected to the back of the protective clamp 11. A guide clamp 8 is fixedly installed on the outside of the filter cartridge 14. The main body 1 of the device is vertically arranged in a "Z" shape. The front is open. The protective side plate 2 protrudes along the top and bottom outer sides of the main body 1, forming a semi-enclosed arrangement for the first purification structure 3 and the second purification structure 4. The open arrangement of the main body 1 and the protective side plate 2 on the outer side facilitate the operation of the purification structure while providing a protective enclosure.

[0032] Two sets of support seats 6 are provided, located on the top and bottom surfaces of the front of the main body 1 of the device. The support seats 6 provide support for the two sets of purification structures. The guide clamp 8 is an arc-shaped plate located inside the conveying box 7 on one side, below the protective clamp 11. The protective clamp 11 is an arc-shaped plate that partially surrounds the limiting cylinder 12. After the sewage is purified by the purification components in the first purification structure 3, it flows downward and is discharged through the filter cylinder 14. At this time, the guide clamp 8 guides the flow of sewage, and the protective clamp 11 enhances the protection of the limiting cylinder 12.

[0033] The fixing buckle 13 is L-shaped and is fixedly connected to the protective clamp 11. At the same time, its outer end is fixedly fastened to the surface of the device body 1. The fixing buckle 13 achieves the effect of fixing the purification structure and the device body 1.

[0034] The limiting cylinder 12 is vertically arranged in a cylindrical shape, and the filter cylinder 14 is a honeycomb filter cylinder. The limiting cylinder 12 facilitates the limiting and fixing of the external purification components, and the filter cylinder 14 facilitates the discharge of purified wastewater.

[0035] It also includes a method of using an apparatus for treating heavy oily wastewater, the method comprising the following steps:

[0036] S1, the first purification structure 3 and the second purification structure 4 are connected by the guide pipe 9 and fixed by the support seat 6;

[0038] S3, the introduced wastewater is first filtered through the limiting cylinder 12 and filter cylinder 14 in the first purification structure 3, and then introduced into the limiting cylinder 12 and filter cylinder 14 in the second purification structure 4 through the guide pipe 9 for secondary filtration, and finally discharged through the guide pipe 9 at the bottom of the second purification structure 4.

[0039] S4. After filtration is complete, tighten the connector 10 to remove the purification column and resin filter column of the dual filter media in the limiting cylinder 12 for cleaning or replacement.

[0040] Users embed the external purification components, including purification columns with dual filter media and resin filter columns, into the limiting cylinders 12 of the two sets of purification structures. Wastewater is introduced through the connector 10, and the wastewater is purified by the purification components in the two sets of limiting cylinders 12. When replacing or cleaning the purification components, the purification components in the limiting cylinders 12 can be removed and cleaned or replaced separately by disassembling the connector 10. Alternatively, the entire purification structure and the main body 1 of the device can be separated for cleaning and replacement.
