[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example: See Figure 1-8 The present invention provides a technical solution: an unattended oil and gas mixed transportation process device, including a mixed transportation component and an intelligent sensor control system, the mixed transportation component is used to realize oil and gas mixed transportation, the mixed transportation component includes a plurality of oil and gas mixed transportation pumps 1 and a dirty oil recovery component 3, the plurality of oil and gas mixed transportation pumps 1 are connected in series through a pipeline 6, the plurality of oil and gas mixed transportation pumps 1 are equipped with a control valve, the intelligent sensor control system is used to control the control valve to make the oil and gas mixed transportation pump 1 run, the pipeline 6 is also provided with a dirty oil recovery component 3 and a buffer tank 2, the buffer tank 2 is used for oil and gas separation, and a buffer 4 is also provided between the dirty oil recovery component 3 and the pipeline 6, the buffer 4 is used to prevent the dirty oil from flowing back;

[0035] The oil-gas mixed transport pump 1 is used to achieve oil-gas mixed transport. In this embodiment, two oil-gas mixed transport pumps 1 are connected in series, and three pumps can also be set. The waste oil recovery component 3 is used to treat oil-containing sludge. The oil-containing waste oil contains oil of a certain purity. The sludge can be removed by the waste oil recovery component 3 to achieve the function of extracting oil. Recycling this part of oil can reduce the waste of oil, and this part of oil can be used in a concentrated manner later to prevent a large amount of oil loss. The control valve is used to control the outlet and inlet volume of the oil-gas mixed transport pump 1. In the process of oil-gas mixed transport, The generated dirty oil is transmitted to the position of the dirty oil recovery component 3. Before reaching the dirty oil recovery component 3, it will first pass through the buffer 4. When the dirty oil recovery component 3 is not in the state of conveying dirty oil to the dirty oil recovery component 3, the buffer 4 plays the role of temporarily storing the dirty oil in the middle to prevent the dirty oil from flowing back into the pipeline of the previous process, which can effectively prevent the dirty oil from flowing back and polluting the clean and processed oil. Or when the dirty oil recovery component 3 fails, the buffer 4 is used to prevent the dirty oil from continuing to be introduced into the dirty oil recovery component 3, which can reduce the further loss of the dirty oil recovery component 3.

[0036] The oil-gas mixed transport pump 1 can achieve large displacement and high oil-gas ratio oil-gas mixed transport, with a flow rate exceeding 5000m3 / d, of which the liquid flow rate is 200m 3 / d, oil and gas are directly transported to the oil and gas mixed transport pump, which reduces the process flow and capital investment, and is automatically controlled. The site is unattended, which reduces labor costs and realizes oil and gas mixed transportation, which can effectively reduce the emission pollution of associated gas and greatly improve the operation efficiency. The dirty oil recovery component 3 includes a dirty oil tank 31, and a rotating shaft 32 and two groups of reaction barrels 34 are arranged inside the dirty oil tank 31. The rotating shaft 32 is vertically arranged, and one end of the rotating shaft 32 is fixedly connected to the output shaft of the motor 35. The motor 35 is arranged on the top of the dirty oil tank 31, and a slide groove 33 is opened on the two opposite surfaces of the rotating shaft 32 in the vertical direction. A spiral groove 36 is opened on the inner wall of the dirty oil tank 31. The outer walls of the two groups of reaction barrels 34 are respectively slidably connected to the two slide grooves 33 through the first slider, and the outer walls of the two groups of reaction barrels 34 are slidably connected to the spiral groove 36 through the second slider. An oil inlet 37 and an oil outlet 38 are arranged on the top of the dirty oil tank 31, and a stirring component 5 is arranged inside the two groups of reaction barrels 34;

[0037] The dirty oil tank 31 serves as the outer shell of the entire dirty oil recovery component 3 to support and protect the equipment. The rotating shaft 32 is used to drive two groups of reaction barrels 34, so that the two groups of reaction barrels 34 can make spiral motion inside the dirty oil tank 31. The two groups of reaction barrels 34 are divided into barrel A and barrel B. In the initial state, the reaction barrel 34 is filled with clean water. The reaction barrel 34 is used to separate water, sludge and oil to achieve the effect of separating oil and sludge, so that the oil with a certain purity in the sludge can be recovered. The reaction barrel 34 is divided into two barrels. When barrel A is in a reaction state, barrel B is in a static state and does not work. Bucket A in a reaction state is used to stratify water, oil and sludge, while barrel B in a static state is used to receive the water in the stratification of barrel A. After the process of pumping oil and discharging sludge is completed, barrel B and barrel A exchange positions due to the drive of the rotating shaft 32. At this time, barrel B serves as a reaction. The reaction barrels 34 are used, and barrel A is used to receive the water in the layers in barrel B. In this way, oil is repeatedly recovered from multiple batches of oily sludge. Clean water is used to separate the oil and sludge into layers, with water in the middle layer, oil in the upper layer of the water, and sludge in the lower layer of the water. After stratification, it is convenient to separately treat the three layers. Compared with one reaction barrel 34, the two groups of reaction barrels 34 do not need to repeatedly take out and put in water, and there are certain difficulties in taking away the water in the middle layer. The two groups of reaction barrels 34 can effectively solve the problem of treating the water in the middle layer. The oil layer and the sludge layer will not be affected by guiding them away, and guiding away and filling another reaction barrel 34 with water are achieved synchronously, which greatly improves the utilization efficiency of clean water. The motor 35 is used to drive the rotating shaft 32 to rotate, and the rotation of the rotating shaft 32 is used to drive the two groups of reaction barrels 34 to make spiral motion around the rotating shaft 32, such as Figure 2, barrel A is on the right side of the rotating shaft 32, and barrel B is on the left side. When the rotating shaft 32 rotates, barrel A will rotate around the rotating shaft 32 to the position of barrel B, and barrel B will rotate around the rotating shaft 32 to the position of barrel A. Barrels A and B will not rotate on their own. The slide groove 33 and the spiral groove 36 jointly realize the spiral transposition function of the two groups of reaction barrels 34 when the rotating shaft 32 rotates. The stirring component 5 is used to add medicine to the inside of the reaction barrel 34. The addition of medicine is used to achieve the stratification of oil, water and sludge. The stirring component 5 is also used to fully mix the medicine and the oil-containing sludge during the dosing process to obtain the best reaction effect. The two groups of reaction barrels 34 can save time for changing clean water, and at the same time effectively solve the problem that the water in the middle layer is difficult to guide away, so that the use efficiency of clean water is improved.

[0038] The two groups of reaction barrels 34 are arranged at different heights inside the dirty oil tank 31, and the oil inlet 37 and the oil outlet 38 are both arranged above the higher group of reaction barrels 34;

[0039] The rotating shaft 32 can realize the displacement of the two groups of reaction barrels 34, so that the two groups of reaction barrels 34 are at different heights. The two groups of reaction barrels 34 at different heights use the principle of communicating vessels to guide water away. The oil inlet 37 and the oil outlet 38 are both arranged above the higher group of reaction barrels 34. Figure 2 Above barrel A are the oil inlet 37 and the oil outlet 38. The barrel at a higher position is the barrel in the reaction state. The oil inlet and the oil outlet are set relative to the reaction barrel 34. The oil inlet is used to introduce oily sludge, and the oil outlet is used to suck away the stratified oil to complete the oil recovery.

[0040] A heating coil 39 is provided at the bottom of the reaction barrel 34, and the stirring assembly 5 includes a fixed shaft 51, the top of the fixed shaft 51 penetrates and extends to the top of the dirty oil tank 31, and the bottom of the fixed shaft 51 is fixedly connected to the reaction barrel 34. A plurality of stirring rods 52 are provided on the fixed shaft 51, and the interiors of the fixed shaft 51 and the stirring rod 52 are both hollow. A feed inlet 53 is provided at the top of the fixed shaft 51, and a plurality of discharge ports 54 are distributed on the fixed shaft 51 and the stirring rod 52;

[0041] The heating coil 39 is used to heat the clean water inside barrel A so that the temperature inside barrel A is under reaction conditions, so that the drug reaction effect is better, so as to obtain a better stratification effect. The fixed shaft 51 is used as the input end for drug feeding and as the supporting part of the stirring rod 52. The fixed shaft 51 is used as the drug feeding end, and the stirring rod 52 is used as the drug discharging end. At the same time, the stirring rod 52 is used to stir the oily sludge. Several discharge ports 54 are used to allow the drugs to be fully dispersed in various directions inside the reaction barrel 34. High-pressure impact drug feeding and several discharge ports 54 allow the drugs to be diffused to the greatest extent. At the same time, high-pressure impact is also used to drive the stirring rod 52 to rotate with the fixed shaft 51 as the axis. While the high-pressure impact drug feeding, with the rotation of the stirring rod 52 and the distribution of several discharge ports 54, the drugs can enter the interior of the sludge. While the sludge is dispersed, the contact area between the drug and the sludge can be larger, which is conducive to further improving the reaction effect of the drugs and effectively improving the stratification effect of the oily sludge.

[0042] The feed port 53 is used for high-pressure impact feeding of medicine;

[0043] The fixed shaft 51 includes a plurality of first connecting shafts 511 and a plurality of second connecting shafts 512, which are alternately arranged. The diameter of the second connecting shaft 512 is smaller than that of the first connecting shaft 511. One end of the stirring rod 52 is fixedly connected to the sleeve 55. The sleeve 55 is sleeved on the second connecting shaft 512. Both ends of the sleeve 55 are in contact with and connected to the end of the first connecting shaft 511. A first opening is opened at one end of the stirring rod 52, and a second opening 56 is provided on the sleeve 55. The middle part of the second connecting shaft 512 is disconnected, and the first opening and the second opening 56 are connected correspondingly. A rotating drum 57 is provided at one end of the second opening 56. The height of the rotating drum is greater than the length of the disconnection in the middle of the second connecting shaft 512. The outer side of the rotating drum is slidably connected to the inner wall of the second connecting shaft 512. A spiral blade is provided at the top of the rotating drum, and the middle part of the top of the rotating drum is connected to the second opening.

[0044] A plurality of first connecting shafts 511 and second connecting shafts 512 together form a fixed shaft 51. The second connecting shaft is provided to facilitate driving the stirring rod 52. The two ends of the sleeve 55 are used for limiting between the first connecting shaft 511, and play the role of receiving the stirring rod 52 and the internal rotating drum 57. The middle disconnection of the second connecting shaft and the second channel are used to connect one end of the stirring rod 52 with the rotating drum 57 inside the second connecting rod. The rotating drum 57 serves as an intermediate component, and the two ends of the rotating drum 57 will not be separated from the two disconnected sections of the second connecting shaft 512. The two ends of the entire fixed shaft 51 are fixed and the rotating drum 57 is The action prevents the disconnected second connecting shafts 512 from detaching, and the spiral blades 58 are used to bear the high-pressure impact force, which causes the drum 57 to rotate inside the second connecting shaft 512, thereby causing the sleeve 55 and the stirring rod 52 to rotate along with the drum 57. In other words, the high-pressure impact force is used to feed the medicine by high-pressure impact, and is also used to drive the drum 57 to rotate while feeding the medicine, thereby causing the stirring rod 52 to rotate, so that the medicine can break up the sludge as the stirring rod 52 rotates and further fully contact with the oil-containing sludge, which is beneficial to improving the sludge being broken up and making the oil-containing sludge stratification effect better.

[0045] The inner wall of the reaction barrel 34 is fixedly connected to a plurality of baffles, which are arranged obliquely relative to the axis of the reaction barrel 34, and the plurality of baffles and the plurality of stirring rods 52 are arranged alternately;

[0046] When the oily sludge is suspended in the water, the rotation of the stirring rod 52 causes the oily sludge to rotate as well, and the plurality of baffles 59 further play a role in breaking up the oily sludge, thereby achieving a better effect of separating the oil from the sludge.

[0047] A grille plate 61 is provided inside the dirty oil tank 31, and the grille plate 61 includes an inner plate 611 and an outer plate 612. The inner plate 611 is fixedly connected to the rotating shaft 32, and the outer side of the outer plate 612 is fixedly connected to the inner wall of the dirty oil tank 31. A first annular channel 62 is provided between the inner plate 611 and the outer plate 612, and a second annular channel is provided on the top of the dirty oil tank 31. The fixed shaft 51 passes through the first annular channel 62 and the second annular channel. A fixed sleeve of the fixed shaft 51 is provided with a limit block 1 63 and a limit block 2 64. The limit block 1 63 is slidably connected to the inner side of the top of the dirty oil tank 31, and the limit block 2 64 is slidably connected to the outer side of the top of the dirty oil tank 31.

[0048] The grille plate 61 is used to filter out large impurities such as large stones when the oily sludge enters barrel A from the oil inlet 37. When barrels A and B exchange positions, the first annular channel 62 is used to move the fixed shafts 51 in the two groups of reaction barrels 34 in the first annular channel, and the second annular channel is also used to move the fixed shaft 51. The limit block 1 63 and the limit block 2 64 are used to limit the fixed shaft 51 so that the fixed shaft 51 will not move up and down axially by itself.

[0049] The portion of the fixed shaft 51 between the upper surface of the reaction barrel 34 and the limit block 63 is retractable; the portion of the fixed shaft 51 between the upper surface of the reaction barrel 34 and the limit block 63 is retractable and is used to correspond to the high and low positions of the two groups of reaction barrels 34 when the A and B barrels are exchanged. When it is located at the position of the A barrel, the position of the fixed shaft 51 between the upper surface of the reaction barrel 34 and the limit block 63 is in a compressed state; when it is located at the position of the B barrel, the position of the fixed shaft 51 between the upper surface of the reaction barrel 34 and the limit block 63 is stretched.

[0050] A connecting channel 321 is provided inside the rotating shaft 32. Both ends of the connecting channel 321 respectively penetrate the first slider and are connected to the two groups of reaction barrels. Solenoid valves are provided inside both ends of the connecting channel 321. The connecting channel 321 is used to guide the water inside the relatively higher reaction barrel 34 into the relatively lower reaction barrel 34.

[0051] The connecting channel 321 utilizes the principle of communicating vessels to guide the water at a high position into the reaction barrel 34 at a low position. That is, after the water and petroleum sludge are stratified, the connecting channel can be used to guide the water in barrel A into barrel B. After the rotating shaft 32 rotates to exchange the positions of barrels A and B, the recycled water guided into barrel B is used as the next reaction environment circulation. The solenoid valve is used to control the closing of the connecting channel 321. The water in the reaction environment can be effectively recycled through the connecting channel 321 without being discharged, thereby effectively reducing the waste of water resources.

[0052] Working principle of the present invention: The process of the oil-gas mixed transportation device is as follows: In the process of oil-gas mixed transportation, the oil-containing sludge generated is used to recover the oil through the dirty oil tank 31, and the sludge is filtered out from the oil by stratification to reduce the waste of oil. The oil recovery is completed through the steps of adding water, heating, adding oil, adding medicine, stirring, standing, sucking oil, guiding water, and removing sludge: clean water is added to barrel A as a reaction environment, and the clean water is heated by the heating coil 39. The temperature of the reaction environment is conducive to improving the stratification effect. The oil-containing sludge is introduced into the inside of barrel A through the oil inlet, and larger particulate impurities are intercepted by the grille plate 61. The remaining oil-containing sludge is mixed with the clean water preliminarily, and the medicine is introduced from the feed port 53 by high-pressure impact feeding. The medicine is used to separate the sludge and the oil, and the medicine is sprayed into the reaction environment through the discharge port on the fixed shaft 51 and the stirring rod 52. At the same time, the impact force of the high-pressure gas and the medicine causes the spiral blade 58 to be pushed, so that the rotor The cylinder 57 rotates, so that the stirring rod 52 rotates inside the A barrel, so that the drug can not only be dispersed in the areas of various directions inside the A barrel, but also the contact area between the drug and the oily sludge can be increased, and the sludge can be broken up so that the drug can be fully mixed with the sludge, so that the reaction speed is faster, which is beneficial to improving the reaction efficiency and can effectively save the time for the stratification of oil, water and sludge. The stirring of adding drugs is carried out simultaneously. After standing for a certain period of time, the oil in the upper layer, the water in the middle layer and the sludge in the lower layer are obtained in the A barrel. The oil in the upper layer is sucked away by suction through the oil outlet 38, and the clean water in the middle layer is guided to the B barrel through the connecting channel 321. Finally, the sludge in the lower layer is removed, that is, the processing and recovery of a batch of oil is completed. At this time, the motor 35 rotates to rotate the rotating shaft 32, and the B barrel is displaced to the bottom as the rotating shaft 32 rotates, and the B barrel is displaced to the top as the rotating shaft 32 rotates, and the B barrel processes the next batch of oily sludge.
