Description

Technical Field

[0001] The invention relates to the technical field of sewage separation, in particular to an oil component enrichment and separation treatment device for oily sewage. Background Art

[0002] Petrochemical industry is the main source of oily wastewater. In onshore oil development, a large amount of oily wastewater is generated in each production link from drilling to oil production, especially secondary oil recovery with water injection as the main means and tertiary oil recovery with polymer solution injection as the main means. A large amount of oily wastewater is also generated in the petrochemical industry. With the rapid development of the national economy, especially the rapid development of industrial production, the amount of oily wastewater generated is increasing, the difficulty of treating oily wastewater is increasing, and the pollution caused by oily wastewater to the environment is becoming more and more serious;

[0003] The existing oil components are usually separated by mixing with flocculants and utilizing the density difference between oil and water to separate the oil and water. However, natural separation takes a long time and results in low separation efficiency. Summary of the invention

[0007] The sewage is first transported to the sedimentation chamber through the input port, where water and impurities are separated, and then the water mixed with oil is transported from the sedimentation chamber to the oil removal chamber, so that the water is deoiled in the oil removal chamber, so that the oil and water are separated. After the oil is separated, it rises to the side close to the impurity chamber, and then flows from the top of the oil removal chamber to the impurity chamber under the action of the treatment device, so that the oil falls into the impurity chamber, and the separated water is output through the oil removal chamber. Finally, the impurities in the sedimentation chamber are discharged through the impurity removal port, and the separated oil is output through the oil outlet.

[0010] Preferably, a No. 1 motor is provided in the conveying body, and the driving shaft of the No. 1 motor is connected to the rotating body. A nut is also provided inside the vibration chamber, and the nut is meshed with the worm. An airbag is provided at the bottom of the nut, and an air inlet is provided on the side of the airbag close to the outside of the body. A plurality of jet ports are provided on the inner wall of the oil removal chamber, and a plurality of the airbags are connected to the jet ports through pipes.

[0011] Preferably, the worm is composed of a fixed shaft and two spiral pieces, two movable grooves are symmetrically arranged on the fixed shaft, the spiral pieces are arranged in the movable grooves, and an electromagnetic spring is arranged between the spiral pieces and the movable grooves.

[0012] Preferably, a rotating shaft is provided in the body, a No. 2 motor is provided on the top of the body, a driving shaft of the No. 2 motor is connected to the rotating shaft, a blocking plate is provided on the shaft arm of the rotating shaft located in the sedimentation chamber, the blocking plate is connected to the sedimentation chamber, the rotating shaft is rotatably connected to the blocking plate, a plurality of penetration holes are provided on the blocking plate, and the blocking plate is arc-shaped.

[0013] Preferably, a plurality of stirring plates are provided on the shaft arm of the rotating shaft located in the oil removal chamber, and the stirring plates are rotatably connected to the oil removal chamber. A plurality of scraping plates are provided near the top of the oil removal chamber of the rotating shaft, and the bottom of the scraping plate extends into the oil removal chamber, and a plurality of bristles are provided at the bottom of the scraping plate.

[0014] Preferably, the diameter of the bottom of the oil removal chamber is larger than the diameter of the top of the oil removal chamber, and the diameter of the top of the oil removal chamber is larger than the diameter of the middle of the oil removal chamber.

[0015] Preferably, a hollow tube is provided inside the rotating shaft, a side of the hollow tube close to the oil removal chamber is provided with a plurality of connecting tubes, a water storage tank is provided outside the machine body, and the hollow tube is connected to the water storage tank through a pipeline.

[0016] The sewage is transported to the sedimentation chamber through the input port. At this time, the sewage is transported to the side of the baffle plate away from the oil removal chamber, and then the baffle plate blocks the impurities. The baffle plate is arc-shaped, so that after the sewage is stratified in the sedimentation chamber, the separated water will approach the arc top of the baffle plate, and then the water can penetrate through the permeation hole to the side of the baffle plate close to the oil removal chamber, thereby achieving the separation of water and impurities;

[0017] When the water and sewage are separated, the controller controls the No. 1 motor to drive, and the driving shaft of the No. 1 motor drives the rotating body to rotate, and then the worm and the auger rotate around the axis of the transmission pipe. When the auger rotates, the water in the sedimentation chamber is transported, and the water is transported to the oil removal chamber through the transmission pipe under the action of the auger;

[0018] When the worm rotates, the electromagnetic spring between the spiral piece and the moving groove is in a power-off state, and then the spiral piece extends out of the moving groove and is in a meshing state with the nut. Since an air bag is provided at the bottom of the nut, the nut moves vertically along the axis of the vibration chamber under the meshing action of the spiral piece. When the nut is in the process of rising, the air bag is in an inflated state, and air continuously enters the air bag; when the nut moves to the top of the vibration chamber, the controller controls the electromagnetic spring to energize, and then the electromagnetic spring contracts, and then the electromagnetic spring drives the spiral piece to contract into the moving groove. At this time, the spiral piece is disconnected from the nut, and then the nut loses the restriction of the spiral piece, and the nut falls under the action of gravity. During the falling process, the nut squeezes the air bag and hits the bottom of the vibration chamber. After being squeezed, the air bag outputs gas to the jet port, and then the vibration generated by the impact is transmitted to the oil removal chamber.

[0019] Several No. 1 motors are started in sequence under the control of the controller, and then several nuts fall in sequence when they move to the top of the vibration chamber, so that the gas ejected from the airbag is always ejected to the degreasing chamber without intermittent ejection;

[0020] During the process of conveying water and oil to the oil removal chamber, the controller controls the No. 2 motor to drive, and the driving shaft of the No. 2 motor drives the rotating shaft to rotate. During the rotation of the rotating shaft, the stirring plate is driven to rotate. When the stirring plate rotates, the water in the oil removal chamber is stirred, so that the water mixed with the oil moves to the side close to the inner wall of the oil removal chamber, and the gas sprayed by the airbag is sprayed from the jet nozzle provided on the inner wall of the oil removal chamber. When the sprayed gas encounters the stirring plate, it is broken up into small bubbles by the stirring plate, and the vibration generated by the falling nut is transmitted to the oil removal chamber. The vibration can increase the collision chance between oil droplets, prompting small oil droplets to gather into large oil droplets, accelerating their floating process, and through vibration, the viscosity of water can be reduced. The hysteresis allows the bubbles to entrain the oil droplets, helping the oil droplets to move to the water surface faster, thereby accelerating the efficiency of water-oil separation and reducing the time of oil-water separation; since the diameter of the bottom of the oil removal chamber is larger than the diameter of the top of the oil removal chamber and larger than the diameter of the middle of the oil removal chamber, the oil droplets move along the inner wall of the oil removal chamber under the action of the bubbles, so that after the oil droplets move to the water surface, when the oil droplets move from the bottom of the oil removal chamber to the middle of the oil removal chamber, the flow speed of the oil droplets is accelerated due to the narrowing of the diameter, and when the oil droplets move from the middle of the oil removal chamber to the top of the oil removal chamber, the flow speed of the oil droplets is slowed down due to the widening of the diameter, and then the flow speed of the oil droplets is limited, thereby improving the efficiency of oil-water separation;

[0021] When the rotating shaft rotates, the scraper plate is driven to rotate. Since the bottom of the scraper plate extends into the oil removal chamber, and bristles are arranged on the bottom of the scraper plate, when the scraper plate rotates, the bottom of the scraper plate extends into the oil and water separation, pushing the oil to the surface of the scraper plate as much as possible, and then flowing from the surface of the scraper plate to the impurity chamber, thereby separating the oil;

[0022] Due to the rotation of the stirring plate, the oil droplets and water flow to the side close to the oil removal chamber, and then the water close to the rotating shaft flows through the connecting pipe to the hollow pipe, and then the water is transported from the oil removal chamber to the water storage tank.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Driven by motor No. 1, the rotating body rotates in the transmission pipe and the vibration chamber, so that in the process of completing the sewage transportation, the worm and the nut are meshed, so that the worm drives the nut to rotate, and then the air bag is stretched when the nut rises, so that the air bag is inflated, and when the nut reaches the top of the vibration chamber, the spiral sheet shrinks to the moving groove on the fixed shaft under the action of the electromagnetic spring, so that the nut loses the meshing connection with the worm, and then the nut falls under the action of gravity, and squeezes the air bag to produce gas, and when the nut falls, it hits the vibration chamber to generate vibration, and the vibration is transmitted to the oil removal chamber. The vibration can increase the collision chance between oil droplets, prompting small oil droplets to gather into large oil droplets, and accelerate their floating process. In addition, through vibration, the viscosity of water can be reduced, so that the bubbles can entrain the oil droplets, helping the oil droplets to move to the water surface faster, thereby accelerating the efficiency of water and oil separation and reducing the time of oil-water separation.

[0025] 2. Since the diameter of the bottom of the oil removal chamber is larger than the diameter of the top of the oil removal chamber and larger than the diameter of the middle of the oil removal chamber, the oil droplets move along the inner wall of the oil removal chamber under the action of bubbles, so that after the oil droplets move to the water surface, when the oil droplets move from the bottom of the oil removal chamber to the middle of the oil removal chamber, the flow speed of the oil droplets is accelerated due to the narrowing of the diameter, and when the oil droplets move from the middle of the oil removal chamber to the top of the oil removal chamber, the flow speed of the oil droplets is slowed down due to the widening of the diameter, and then the flow speed of the oil droplets is limited, thereby improving the efficiency of oil-water stratification.

The rotating body 27 passes through the vibration chamber 26 and the transmission tube 25 in sequence. The rotating body 27 is composed of a worm 271 and an auger 272. The worm 271 is located in the vibration chamber 26, and the auger 272 is located in the transmission tube 25.

The spiral pieces 276 are arranged in the movable grooves. An electromagnetic spring is arranged between the spiral pieces 276 and the movable grooves.

[0043] Preferably, the diameter of the bottom of the oil removal chamber 22 is larger than the diameter of the top of the oil removal chamber 22 , and the diameter of the top of the oil removal chamber 22 is larger than the diameter of the middle of the oil removal chamber 22 .

[0044] Working principle of the present invention:

[0045] The sewage is transported to the sedimentation chamber 21 through the input port. At this time, the sewage is transported to the side of the baffle plate 12 away from the oil removal chamber 22, and then the baffle plate 12 blocks the impurities. The baffle plate 12 is arc-shaped, so that after the sewage is stratified in the sedimentation chamber 21, the separated water will approach the arc top of the baffle plate 12, and then the water can penetrate through the permeation hole to the side of the baffle plate 12 close to the oil removal chamber 22, thereby achieving separation of water and impurities;

[0046] When the water and sewage are separated, the controller controls the No. 1 motor to drive, and the driving shaft of the No. 1 motor drives the rotating body 27 to rotate, and then the worm 271 and the auger 272 rotate around the axis of the transmission pipe 25. When the auger 272 rotates, the water in the sedimentation chamber 21 is transported, and the water is transported to the oil removal chamber 22 through the transmission pipe 25 under the action of the auger 272;

[0047] When the worm 271 rotates, the electromagnetic spring between the spiral piece 276 and the moving groove is in a power-off state, and then the spiral piece 276 extends out of the moving groove and is in a meshing state with the nut 273. Since the air bag 274 is provided at the bottom of the nut 273, the nut 273 moves vertically along the axis of the vibration chamber 26 under the meshing action of the spiral piece 276. When the nut 273 is in the process of rising, the air bag 274 is in an inflated state, and air is continuously introduced into the air bag 274. When the nut 273 moves to the top of the vibration chamber 26, the air bag 274 is inflated. When the electromagnetic spring 276 is in the moving groove, the controller controls the electromagnetic spring to be energized, and then the electromagnetic spring contracts, and then the electromagnetic spring drives the spiral piece 276 to contract into the moving groove. At this time, the spiral piece 276 is disengaged from the nut 273, and then the nut 273 loses the restriction of the spiral piece 276, and the nut 273 immediately falls under the action of gravity. During the falling process, the nut 273 squeezes the airbag 274 and impacts the bottom of the vibration chamber 26. After being squeezed, the airbag 274 outputs gas to the jet port, and then the vibration generated by the impact is transmitted to the oil removal chamber 22;

[0048] Several No. 1 motors are started in sequence under the control of the controller, and then several nuts 273 fall in sequence when they move to the top of the vibration chamber 26, so that the gas sprayed by the airbag 274 is always sprayed into the degreasing chamber 22 without intermittent spraying;

[0049] In the process of conveying water and oil to the oil removal chamber 22, the controller controls the No. 2 motor to drive, and the driving shaft of the No. 2 motor drives the rotating shaft 11 to rotate. In the process of rotating the rotating shaft 11, the stirring plate 13 is driven to rotate. When the stirring plate 13 rotates, the water in the oil removal chamber 22 is stirred, so that the water mixed with the oil moves to the side close to the inner wall of the oil removal chamber 22, and the gas ejected by the airbag 274 is ejected from the jet nozzle provided on the inner wall of the oil removal chamber 22. When the ejected gas encounters the stirring plate 13, it is broken into small bubbles by the stirring plate 13, and the vibration generated by the falling nut 273 is transmitted to the oil removal chamber 22. The vibration can increase the collision chance between oil droplets, prompting small oil droplets to gather into large oil droplets, accelerating their floating process, and Vibration can reduce the viscosity of water, so that bubbles can entrain oil droplets and help them move to the water surface faster, thereby accelerating the efficiency of water-oil separation and reducing the time of oil-water separation. Since the diameter of the bottom of the deoiling chamber 22 is larger than the diameter of the top of the deoiling chamber 22 and larger than the diameter of the middle of the deoiling chamber 22, the oil droplets move along the inner wall of the deoiling chamber 22 under the action of bubbles, so that after the oil droplets move to the water surface, when the oil droplets move from the bottom of the deoiling chamber 22 to the middle of the deoiling chamber 22, the flow speed of the oil droplets is accelerated due to the narrowing of the diameter, and when the oil droplets move from the middle of the deoiling chamber 22 to the top of the deoiling chamber 22, the flow speed of the oil droplets is slowed down due to the widening of the diameter, and the flow speed of the oil droplets is restricted.

[0050] When the rotating shaft 11 rotates, the scraper plate 14 is driven to rotate. Since the bottom of the scraper plate 14 extends into the oil removal chamber 22, and bristles are arranged on the bottom of the scraper plate 14, when the scraper plate 14 rotates, the bottom of the scraper plate 14 extends into the oil and water separation, pushing the oil to the surface of the scraper plate 14 as much as possible, and then flowing from the surface of the scraper plate 14 to the impurity chamber 23, so as to separate the oil.

[0051] Due to the rotation of the stirring plate 13, the oil droplets and water flow to the side close to the oil removal chamber 22, and then the water close to the rotating shaft 11 flows through the connecting pipe to the hollow pipe 15, and then the water is transported from the oil removal chamber 22 to the water storage tank.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
