Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to intelligent crude oil sewage treatment equipment. Background Art

[0002] Typically, oilfield crude oil wastewater treatment involves pumping oily wastewater into a sedimentation and de-oiling tank for initial sedimentation and separation. Crude oil above the oil-water interface overflows through an overflow tank, while wastewater below the oil-water interface settles before secondary reinjection. Sludge is discharged through a sludge pipe at the bottom of the tank. This natural sedimentation method for crude oil wastewater treatment can generally only handle large oil particles with a diameter of 50 microns or more. Because smaller particles are difficult to settle quickly, suspended oil particles with a diameter of 10-30 microns must be discharged with the wastewater, wasting crude oil and impacting the environment.

[0003] The prior art discloses a crude oil wastewater treatment device designed to address the problem of discharging wastewater containing suspended oil particles with a diameter of 10-30 microns. The device comprises a water distribution and collection tube within a settling tank, a sewage pipe connected to the water distribution tube, a dissolved air water pipe, and an oil collection tank, a central mud discharge pipe connected to the water collection tube, a drainage pipe, and an outlet pipe, all connected in sequence to the outlet pipe, a shutoff valve, a filter, a flowmeter, a clean water shutoff valve, a dissolved air pump, a check valve, a bubble separator, a dissolved air water pressure reducing valve, and a dissolved air water pipe. The dissolved air pump in this crude oil wastewater treatment device draws clean water from the collection tube and air from the settling tank, forming a dissolved air-water mixture. This mixture is suddenly released by a spring release, generating a large number of tiny bubbles that adhere to suspended matter or crude oil particles in the oily wastewater before being discharged from the tank. This invention can treat crude oil wastewater containing suspended oil particles with a diameter of 10-30 microns with excellent treatment effectiveness and high efficiency, reducing crude oil waste and meeting environmental protection requirements.

[0004] However, the existing technology, especially this solution, still has the following problems: the fixed oil collecting tank in the existing solution cannot adapt to liquid level fluctuations, and the collection efficiency drops sharply when the oil layer is thin; high-viscosity oil easily adheres to the tank wall to form hard oil scale, and the existence of flow dead zones in the edge area will also affect the discharge efficiency after crude oil wastewater treatment. Summary of the Invention

[0005] The purpose of the present invention is to provide a technical solution to improve the efficiency of impurity discharge by operating a flexible frame through a dynamic diversion mechanism, so as to solve the problems in the prior art raised in the above background technology.

[0006] To achieve the above object, the present invention adopts the following technical solutions: An intelligent crude oil wastewater treatment device, comprising: The settling box and the treatment chamber are located at the bottom of the settling box. Two sets of aeration pipes are installed inside the treatment chamber. Untreated crude oil wastewater enters from the wastewater inlet pipe at the bottom of the treatment chamber. The impurities generated after being treated by the two sets of aeration pipes reach the liquid surface of the settling box. A discharge pipe for discharging the impurities is provided on the inner wall of the settling box. A flexible guide frame is provided above the interior of the sedimentation box. The flexible guide frame is located at one end of the discharge pipe and can be deformed to generate a guiding flow path. A water pump is provided inside the sedimentation box at the other end of the discharge pipe. The water pump generates water flow on the liquid surface of the sedimentation box to push impurities out of the discharge pipe.

[0007] Preferably, the two aeration tube groups are aeration tube group one and aeration tube group two, the aeration tubes of aeration tube group one and aeration tube group two are arranged alternately, the aeration tube group includes a tube group frame and multiple groups of aeration tubes, and the aeration tubes are connected side by side inside the tube group frame.

[0008] Preferably, the spacing between the multiple groups of aeration tubes of the aeration tube group one can be adjusted, and the aeration tube group one is provided with an equidistant variable distance structure for adjusting the spacing between the multiple groups of aeration tubes. A flexible cloth surface is provided between the tube group frame and the aeration tubes of the aeration tube group one, and a flexible cloth surface is provided between two groups of aeration tubes in the aeration tube group one; the spacing between the multiple groups of aeration tubes of the aeration tube group two cannot be adjusted, and the flexible cloth surface is used to block the flow direction of untreated crude oil wastewater. The crude oil wastewater can be fully aerated after passing through the aeration tube group one and the aeration tube group two.

[0009] Preferably, flexible pipes are provided at both ends of the aeration tubes of the aeration tube group one, and the aeration tubes are connected to the tube group frame through the flexible pipes. The provision of the flexible pipes allows the spacing between the multiple groups of aeration tubes in the aeration tube group one to be adjusted, and the size of the adjustable spacing between the multiple groups of aeration tubes is positively correlated with the content of suspended oil particles contained in the crude oil wastewater. The sewage inlet pipe is provided with a detection sensor for detecting the content of suspended oil particles contained in the crude oil wastewater and the diameter distribution of the suspended oil particles.

[0010] Preferably, the interior of the sedimentation tank is provided with a plurality of groups of vertically arranged water pumping pipes, and the sedimentation tank is provided with a control pump for driving the water pumping pipes. The water pumping pipes are located at one end of the bottom of the sedimentation tank and are used to control the liquid level inside the sedimentation tank. A water pump pipe is provided in the middle of the water pumping pipes for extracting impurities floating on the liquid surface, and the water pump pipes are provided with a plurality of groups of inlets along the vertical direction.

[0011] Preferably, multiple groups of liquid level sensors are distributed on the upper edge of the flexible guide frame. When the liquid level sensor detects that the impurity liquid level inside the flexible guide frame exceeds a set value, multiple groups of pumping pipes extract the impurities or liquid inside the sedimentation box to lower the liquid level.

[0012] Preferably, the flexible guide frame is configured as a frame structure that fits the shape of the inner wall of the sedimentation box. The flexible guide frame deforms in such a way that the width of one end close to the discharge pipe becomes smaller, while the width of the other end remains unchanged. During this process, the frame of the flexible guide frame is always in a vertical state, thereby generating a guiding flow path.

[0013] Preferably, the flexible guide frame is provided with multiple groups of traction bars along the inner wall, and the traction bars are arranged in a vertical direction. The multiple groups of traction bars are arranged in pairs on the inner wall of the flexible guide frame. The corresponding two groups of traction bars are pulled close together by traction ropes, and the two ends of the traction ropes are respectively connected to the corresponding two groups of traction bars. A winch for winding the traction rope is provided on the settlement box, and the traction rope pulls the traction bar to change the shape of the flexible guide frame.

[0014] Preferably, a reset structure is provided between the outer wall of the flexible guide frame and the settlement box. The reset structure is used to restore the shape of the flexible guide frame after deformation. The reset structure includes a spring and a pull rope structure. When the flexible guide frame needs to be reset after deformation and contraction, the traction rope is relaxed and the spring and pull rope structure can pull the outer wall of the flexible guide frame so that the flexible guide frame returns to a state of being in contact with the inner wall of the settlement box.

[0015] Preferably, the sewage inlet pipe is provided with a dispersion inlet at one end of the bottom of the treatment chamber. The dispersion inlet is used to disperse the crude sewage that initially enters the treatment chamber, so that the crude sewage is more evenly dispersed upward to the aeration tube group 1 and the aeration tube group 2. The dispersion inlet is arranged as multiple groups of inlet holes. Such an arrangement can improve the final aeration treatment effect of the crude sewage.

[0016] Technical effects and advantages of the present invention: The intelligent crude oil wastewater treatment equipment proposed by the present invention has the following advantages compared with the existing technology: This invention utilizes a dynamic diversion mechanism to manipulate the flexible guide frame to deform. A winch traction rope shrinks the frame width near the discharge pipe, creating a tapered diversion channel that forces scum to accumulate in the discharge pipe. A water pump works in tandem to generate a directional flow at the liquid surface in the sedimentation tank, pushing scum along the diversion channel. A backflow prevention design ensures that the traction bars and connection points constrain the flexible frame to maintain a vertical position during deformation, preventing scum from re-mixing from the bottom of the frame.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0020] Example: Figures 1 to 7 As shown, the present invention provides an intelligent crude oil wastewater treatment device, comprising: a sedimentation tank 11 and a treatment chamber 28. The treatment chamber 28 is located at the inner bottom of the sedimentation tank 11. Two sets of aeration pipes are provided inside the treatment chamber 28. Untreated crude oil wastewater enters through the sewage inlet pipe 12 at the bottom of the treatment chamber 28. Impurities generated after treatment by the two sets of aeration pipes reach the liquid surface of the sedimentation tank 11. A discharge pipe 16 for discharging the impurities is provided on the inner wall of the sedimentation tank 11. A flexible guide frame 31 is provided above the interior of the sedimentation box 11. The flexible guide frame 31 is located at one end of the discharge pipe 16 and can be deformed to generate a guiding flow path. A water pump 36 is provided inside the sedimentation box 11 at the other end of the discharge pipe 16. The water pump 36 pushes the water flow generated on the liquid surface of the sedimentation box 11 to discharge impurities from the discharge pipe 16.

[0021] Working Principle: A dynamic diversion mechanism guides the deformation of the flexible guide frame 31. A winch 35 pulls the rope 34 to shrink the width of the frame near the discharge pipe 16, forming a tapered diversion channel that forces scum to accumulate in the discharge pipe 16. A water pump 36 works in tandem to generate a directional flow at the liquid surface of the settling tank 11, pushing scum along the diversion channel. A backflow prevention design ensures that the pull bar 32 and connection point 33 constrain the flexible frame to maintain a vertical position during deformation, preventing scum from re-mixing from the bottom of the frame.

[0022] Zero-residue scum discharge. Frame deformation and directional water flow improve scum collection efficiency. Compared to traditional overflow tanks, the system reduces residual scum by adaptively adjusting liquid level fluctuations. A liquid level sensor 37 monitors the liquid level in real time, triggering the pump pipe 14 to adjust the liquid level and ensure the diversion channel remains at the effective working depth. Non-clogging operation, powered by pure hydraulic propulsion and without mechanical scrapers, eliminates the need for moving parts to contact highly viscous scum, eliminating jamming. This purely mechanical structure, combining flexible physical deformation with hydraulic synergy, achieves directional scum diversion and zero-residue discharge, overcoming the passive overflow limitations of traditional fixed oil collection tanks.

[0023] It should be noted that the above-mentioned impurities are oil-gas suspension mixtures formed when the gas generated by the aeration tube group adheres to suspended matter or crude oil particles in the oily wastewater, and are not real impurities. The impurities here can be recycled after being discharged.

[0024] The two aeration tube groups are aeration tube group 1 21 and aeration tube group 2 22 . The aeration tubes 23 of aeration tube group 1 21 and aeration tube group 2 22 are arranged in an alternating manner. The aeration tube group includes a tube group frame 26 and multiple groups of aeration tubes 23 . The aeration tubes 23 are connected side by side inside the tube group frame 26 .

[0025] The spacing between the multiple groups of aeration tubes 23 in the aeration tube group 1 21 can be adjusted. The aeration tube group 1 21 is provided with an equidistant variable distance structure 25 for adjusting the spacing between the multiple groups of aeration tubes 23. A flexible cloth surface 24 is provided between the tube group frame 26 of the aeration tube group 1 21 and the aeration tubes 23. A flexible cloth surface 24 is provided between two groups of aeration tubes 23 in the aeration tube group 1 21. The spacing between the multiple groups of aeration tubes 23 in the aeration tube group 2 22 cannot be adjusted. The flexible cloth surface 24 is used to block the flow direction of untreated crude oil wastewater. The crude oil wastewater can be fully aerated after passing through the aeration tube group 1 21 and the aeration tube group 2 22.

[0026] Flexible pipes 27 are provided at both ends of the aeration pipes 23 of aeration pipe group 1 21. These flexible pipes 27 connect the aeration pipes 23 to the pipe group frame 26. The provision of flexible pipes 27 allows for adjustable spacing between the multiple aeration pipes 23 in aeration pipe group 1 21. The adjustable spacing between the multiple aeration pipes 23 is positively correlated with the content of suspended oil particles in the crude oil wastewater. The sewage inlet pipe 12 is provided with a sensor for detecting the content and diameter distribution of suspended oil particles in the crude oil wastewater, and also includes a controller for controlling the adjustment mode of the equidistant variable pitch structure 25. Specifically, the sensor is configured as an optical sensor group or an acoustic sensor. The optical sensor group uses a laser diffraction particle size analyzer to measure the scattering angle distribution of laser light after it passes through the wastewater to invert particle size, or a turbidity sensor to detect suspended matter concentration by measuring the scattered light intensity. The acoustic sensor uses an ultrasonic attenuation spectrometer to measure the attenuation coefficient of high-frequency ultrasonic waves (1-10 MHz) propagating through the wastewater, which is correlated with particle concentration and particle size.

[0027] The interior of the sedimentation tank 11 is provided with a plurality of vertically arranged water pumping pipes 14, and the sedimentation tank 11 is provided with a control pump 17 for driving the water pumping pipe 14. The water pumping pipe 14 is located at one end of the bottom of the sedimentation tank 11 and is used to control the liquid level inside the sedimentation tank 11. A water pump pipe 15 is provided in the middle of the water pumping pipe 14 to extract impurities floating on the liquid surface. The water pumping pipe 15 is provided with a plurality of groups of inlets in the vertical direction. The length of the water pumping pipe 15 here is greater than the thickness of the impurities suspended on the liquid surface. The suspended impurities enter the interior of the water pumping pipe 15 and the water pumping pipe 14 through the inlet. The purpose of setting the plurality of inlets is to control the liquid level thickness of the impurities inside the sedimentation tank 11 through the water pumping pipe 15, and the water pumping pipe 15 extracts impurities on the liquid surface through the plurality of inlets. Specifically, a selection valve is provided on the water pumping pipe 14, that is, the water pumping pipe 14 can be selected to be drawn from the bottom of the water pumping pipe 14 or the water pumping pipe 15, so there are three extraction methods: extraction from the bottom of the water pumping pipe 14, extraction from the water pumping pipe 15, and extraction from both at the same time.

[0028] Multiple groups of liquid level sensors 37 are distributed on the upper edge of the flexible guide frame 31. When the liquid level sensor 37 detects that the liquid level of impurities inside the flexible guide frame 31 exceeds a set value, multiple groups of pumping pipes 14 extract the impurities or the liquid inside the sedimentation box 11 to lower the liquid level. The set value is set by the staff, and the set value height does not exceed the height of the upper edge of the flexible guide frame 31.

[0029] The flexible guide frame 31 is configured to conform to the shape of the inner wall of the sedimentation tank 11. The flexible guide frame 31 deforms in such a way that its width decreases at one end near the discharge pipe 16 while remaining constant at the other end. During this process, the frame of the flexible guide frame 31 remains vertical, thereby creating a guided flow path. Furthermore, the frame of the flexible guide frame 31 remains vertical to prevent the edge of the flexible guide frame 31 from tipping over, which could cause impurities to flow from the inside of the flexible guide frame 31 to the outside.

[0030] The flexible guide frame 31 is provided with multiple groups of traction bars 32 along the inner wall. The traction bars 32 are arranged in the vertical direction. The multiple groups of traction bars 32 are arranged in pairs on the inner wall of the flexible guide frame 31. The corresponding two groups of traction bars 32 are pulled close together by traction ropes 34. The two ends of the traction ropes 34 are respectively connected to the corresponding two groups of traction bars 32. A winch 35 for winding the traction ropes 34 is provided on the sedimentation box 11. The traction ropes 34 pull the traction bars 32 to change the shape of the flexible guide frame 31.

[0031] Specifically, the traction bar 32 is provided with multiple groups of connection points 33, and the traction rope 34 is also connected to the connection points 33 through multiple groups of connection ropes. The connection points 33 are arranged as follows: Figure 4 The purpose of setting up multiple groups of connection points 33 is to keep the flexible guide frame 31 in an upright state during the deformation process.

[0032] A reset structure is provided between the outer wall of the flexible guide frame 31 and the sedimentation box 11. The reset structure is used to restore the shape of the flexible guide frame 31 after deformation. The reset structure includes a spring and a pull rope structure. When the flexible guide frame 31 needs to be reset after deformation and contraction, the traction rope 34 is relaxed and the spring and pull rope structure can pull the outer wall of the flexible guide frame 31 so that the flexible guide frame 31 returns to a state of being in contact with the inner wall of the sedimentation box 11.

[0033] Specifically, in actual use, the deformation contraction and deformation reset states of the flexible guide frame 31 are cyclical operations. The purpose of the deformation of the flexible guide frame 31 is to generate a flow path that permanently guides the discharge of impurities. After the impurities on the liquid surface are discharged, the flexible guide frame 31 restores its original shape and prepares for the next operation.

[0034] The sewage inlet pipe 12 is provided with a dispersion inlet 13 at one end of the bottom of the treatment chamber 28. The dispersion inlet 13 is used to disperse the crude sewage that initially enters the treatment chamber 28, so that the crude sewage is more evenly dispersed upward to the aeration tube group 1 21 and the aeration tube group 2 22. The dispersion inlet 13 is provided with multiple groups of inlet holes. Such a configuration can improve the final aeration treatment effect of the crude sewage.

[0035] In summary, the present invention has the following comprehensive effects: Aeration optimization mechanism features two staggered aeration tube groups: aeration tube group 1 (21) with adjustable spacing and aeration tube group 2 (22) with fixed spacing, creating an aeration gradient. A flexible fabric surface (24) guides wastewater flow, enhancing contact between oil particles and air bubbles. Intelligent spacing adjustment: Based on real-time sensor data from the wastewater inlet pipe (12), including oil content and particle size distribution, a controller drives the equidistant variable spacing structure (25) to adjust the spacing between aeration tube group 1 (21). Spacing is positively correlated with oil content. Dynamic scum collection is achieved through a flexible guide frame (31): A winch (35) pulls the rope (34) to control deformation, contracting near the discharge pipe (16). Combined with a water pump (36), it generates a directional flow, guiding scum toward the discharge pipe (16). Pull bars (32) and connection points (33) ensure the frame remains upright during deformation, preventing scum from leaking sideways. Layered precise pumping and drainage, multi-stage pumping system: vertical pumping pipe 14 is equipped with pumping pipe 15 with multiple entrance heights, which can selectively extract: bottom sludge, through the bottom of the pumping pipe 14; surface scum, through the inlet of the pumping pipe 15; mixed liquid, extracted simultaneously; liquid level sensor 37 linkage: real-time monitoring of the scum layer thickness, triggering the pumping system to maintain the set liquid level height.

[0036] Aeration efficiency is significantly improved. Dynamic adjustment of the spacing between aeration tubes allows for adaptability to varying oil particle concentrations. For example, at high concentrations, narrowing the spacing enhances aeration. The flexible fabric 24 blocks chaotic water flow, extending oil-gas contact time and improving the removal rate of 10-30μm oil particles. Scum collection achieves zero residue, with the directional contraction of the flexible frame and the propulsion of the water pump 36 improving scum collection efficiency. The vertical anti-rollover design of the frame prevents scum back-mixing and reduces residue. Intelligent stratification processing: The multiple inlets of the pump pipe 14 independently control the scum layer thickness, and the liquid level sensor 37 automatically maintains the optimal separation interface. Strong anti-interference performance: optical and acoustic dual sensor calibration minimizes oil particle detection errors. Distributed inlets 13 evenly distribute water flow to resist flow fluctuations and optimize maintenance costs. The connection between the aeration tubes and the flexible pipe 27 allows for spacing adjustment without disassembly. A reset mechanism, featuring a spring and pull cord, automatically returns the flexible frame to its initial state, minimizing manual intervention.

[0037] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
