[0001] This utility model relates to the field of water treatment technology, and in particular to a pollution-resistant oilfield produced water filtration and treatment device. Background Technology
[0002] During the oilfield extraction process, a large amount of produced water is generated. This produced water contains a variety of impurities, such as suspended solids, oil, and heavy metal ions. If discharged directly, it will cause serious pollution to the surrounding environment.
[0003] Currently, existing oilfield produced water filtration and treatment devices have some shortcomings, such as poor filtration effect, difficulty in effectively removing various pollutants, and easy clogging, which affect treatment efficiency and service life of the device.
[0004] To address these issues, a pollution-resistant oilfield produced water filtration and treatment device is proposed. Utility Model Content
[0005] In order to overcome the shortcomings of existing technologies and solve the problems of poor filtration effect and difficulty in effectively removing various pollutants, this utility model provides a pollution-resistant oilfield produced water filtration and treatment device.
[0006] This utility model is achieved using the following technical solution:
[0007] A pollution-resistant oilfield produced water filtration and treatment device includes a treatment tank and a base. The base is fixed to the bottom of the treatment tank. The upper left and right sides of the treatment tank are respectively provided with an inlet and an outlet. A sewage pipe is connected to the inlet. The treatment tank is provided with a partition, which includes a left partition and a right partition. The partition is fixed inside the treatment tank and divides the treatment tank into three areas, from left to right: a primary filtration tank, a purification tank, and an effluent tank.
[0008] The upper part of the left partition is provided with a connecting port, which connects the primary filter tank and the purification tank. The bottom of the right partition is provided with a notch, which connects the purification tank and the effluent tank.
[0009] The treatment tank is located on the back of the primary filter and has an overflow port. The height of the overflow port is lower than that of the inlet and the connecting port.
[0010] The primary filter tank is equipped with a slag-lifting basket, and the upper end of the slag-lifting basket is symmetrically equipped with two handles. The inner wall of the primary filter tank is symmetrically equipped with two locking blocks, and the slag-lifting basket is locked in the primary filter tank by the locking blocks.
[0011] The height of the slag removal basket is located at the lower end of the water inlet.
[0012] The purification tank is equipped with a filtration device, which includes a water dropper and a filter box. The water dropper is fixed on the inner wall of the purification tank and located at the lower end of the connecting port. A fine filter screen is fixed at the bottom of the water dropper.
[0013] The filter box is fixed to the inner wall of the purification tank and located below the water hopper. The filter box is filled with activated carbon.
[0014] The top of the processing box is provided with a top cover, and the top cover is provided with two inspection ports, and the inspection ports are provided with inspection covers;
[0015] The top of the inspection cover is provided with guide posts, and there are four guide posts, which are fixed around the lower surface of the inspection cover. The upper surface of the inspection cover is provided with a handle.
[0016] The front of the processing box has three viewing windows, which are vertically positioned and located in the left, center, and right areas of the processing box.
[0017] The present invention has the following advantages over the prior art:
[0018] 1. By installing partitions inside the treatment tank, the interior of the treatment tank is divided into a primary filter tank, a purification tank, and an effluent tank. The primary filter tank uses a slag removal basket for initial filtration to intercept larger impurities. The purification tank uses a fine filter screen in the hopper and an activated carbon filter box for further refinement and adsorption filtration, which can effectively remove various impurities from the oilfield produced water and improve water quality.
[0019] 2. By installing a sludge removal basket inside the primary filter tank, which can be installed and removed through the inspection port, the problem of large solid impurities clogging the treatment tank in the primary filter tank is effectively prevented. In addition, the overflow port avoids equipment failure and water quality deterioration caused by excessive water volume. At the same time, each filter component can be cleaned and replaced regularly, ensuring the long-term stable operation of the equipment and giving it a strong anti-pollution capability.

Detailed Implementation
[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] The present invention will be further described below with reference to the accompanying drawings.
[0028] like Figures 1 to 5 As shown, a pollution-resistant oilfield produced water filtration and treatment device includes a treatment tank 1 and a base 2. The base 2 is fixed to the bottom of the treatment tank 1. The upper left and right sides of the treatment tank 1 are respectively provided with an inlet 12 and an outlet 13. A sewage pipe 14 is connected to the inlet 12 for introducing oilfield produced water into the treatment tank 1. The treatment tank 1 is provided with a partition, including a left partition 15 and a right partition 16. The partition is fixed inside the treatment tank 1 and divides the treatment tank 1 into three areas, from left to right: a primary filter tank, a purification tank, and an effluent tank. This partition design allows the produced water to be filtered and treated according to a specific process, improving the treatment effect.
[0029] The upper end of the left partition 15 is provided with a connecting port 151, which connects the primary filter tank and the purification tank, so that the water that has been initially filtered by the primary filter tank can enter the purification tank through the connecting port 151 for further purification. The bottom of the right partition 16 is provided with a notch, which connects the purification tank and the effluent tank. The water treated by the purification tank flows into the effluent tank through the notch and is finally discharged from the effluent outlet 13.
[0030] The treatment tank 1 is located on the back of the primary filter tank and has an overflow port 17. The height of the overflow port 17 is lower than that of the inlet 12 and the connecting port 151. When the water flow rate at the inlet 12 is too large and the water level in the primary filter tank exceeds the height of the overflow port 17, the excess water will be discharged from the overflow port 17 to prevent the water level in the primary filter tank from being too high and causing water to flow back to the inlet 12. It also avoids the filtration effect being affected by excessive water volume.
[0031] The primary filter tank is equipped with a slag removal basket 3. The upper end of the slag removal basket 3 is symmetrically provided with two handles 31. The handles 31 are designed to facilitate the removal of the slag removal basket 3 from the primary filter tank for cleaning. The inner wall of the primary filter tank is symmetrically provided with two locking blocks 18. The slag removal basket 3 is locked in the primary filter tank by the locking blocks 18. The locking blocks 18 ensure that the slag removal basket 3 can be stably placed in the primary filter tank.
[0032] The height of the slag removal basket 3 is located at the lower end of the water inlet 12. This design allows water flowing in from the water inlet 12 to first enter the slag removal basket 3, where larger impurities are intercepted, thus playing a preliminary filtering role.
[0033] The purification tank is equipped with a filtration device, which includes a water dropper 41 and a filter box 4. The water dropper 41 is fixed on the inner wall of the purification tank and located at the lower end of the connecting port 151. Water flowing into the purification tank from the primary filtration tank through the connecting port 151 will first fall into the water dropper 41. A fine filter screen 42 is fixed at the bottom of the water dropper 41. The fine filter screen 42 can further filter out small impurities from the water.
[0034] The filter box 4 is fixed on the inner wall of the purification tank and located below the water dropper 41. The filter box 4 is filled with activated carbon, which has good adsorption properties and can adsorb pollutants such as oil and organic matter in the water, further purifying the water quality.
[0035] The top of the processing box 1 is provided with a top cover 5, and the top cover 5 is provided with two inspection ports 51, and the inspection ports 51 are provided with inspection covers 6; through the inspection ports 51, various components inside the processing box 1 can be inspected and repaired.
[0036] The top of the inspection cover 6 is provided with guide posts 61. There are four guide posts 61, which are fixed around the lower surface of the inspection cover 6. The guide posts 61 can ensure that the inspection cover 6 is accurately aligned with the inspection port 51 during installation, and at the same time play a certain supporting role. The upper surface of the inspection cover 6 is provided with a handle 62, which makes it easy to open and close the inspection cover 6.
[0037] The front of the treatment tank 1 has three viewing windows 11, which are vertically positioned and located in the left, center, and right areas of the treatment tank 1, respectively corresponding to the primary filtration tank, the purification tank, and the effluent tank. Through the viewing windows 11, the water level and filtration status of each area inside the treatment tank 1 can be observed intuitively, facilitating timely understanding of the device's operating status.
[0038] The working principle of this utility model is as follows: When in use, the sewage source is turned on, and the oilfield produced water flows into the primary filter tank of the treatment tank 1 through the sewage pipe 14 from the inlet 12. The water first enters the slag basket 3, and larger impurities are intercepted by the slag basket 3.
[0039] When the water level in the filter tank rises to the height of the connecting port 151, the water flows into the purification tank through the connecting port 151 and falls into the water dropper 41. It passes through the fine filter screen 42 at the bottom of the water dropper 41 to filter out small impurities. The water after passing through the fine filter screen 42 continues to fall and enters the filter box 4. The activated carbon in the filter box 4 adsorbs pollutants such as oil and organic matter in the water, further purifying the water quality. The purified water flows into the outlet tank through the gap at the bottom of the right partition 16 and is finally discharged from the outlet 13.
[0040] During operation, staff can observe the water level and filtration status of each area in the treatment tank 1 through the viewing window 11. When it is found that there are too many impurities in the slag basket 3, the slag basket 3 can be lifted out for cleaning through the handle 31. When it is necessary to inspect or repair other components inside the device, the inspection cover 6 can be opened and the inside of the treatment tank 1 can be entered through the inspection port 51 for operation.
[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
