Description

Technical Field

[0001] The invention relates to the technical field of oil drilling sludge treatment, in particular to a sludge flocculation and electroosmosis combined treatment system. Background Art

[0002] Compared with conventional water-driven oil production wastewater, oilfield produced water not only has the characteristics of conventional water-driven oil production wastewater such as high water temperature, high mineralization, high bacterial content, and large amounts of residual chemicals and other substances, but also the addition of polymers makes it have high viscosity, severe emulsification, strong ability to carry suspended solids, large resistance to the floating or sinking of oil droplets and solid particles, and severe adsorption loss of chemical adsorbents.

[0003] For example, the authorization announcement number "CN212800026U" is named a mixed flocculation treatment system for oily wastewater. The large amount of effluent from the electric flocculation purification device is diverted into a magnetic flocculator with a smaller processing capacity, thereby further reducing the hardness and improving the water quality, so that it can be used in circulating water systems or heat exchange systems and the like. However, in the existing mixed flocculation treatment system for oily wastewater, since flocculants are added into the sludge pool, the flocculants can accelerate the adsorption and sedimentation of suspended matter. Because the addition of flocculants is conventionally required to be manually dumped, and the location for dumping the flocculants is also close to the shore of the sludge pool, the flocculants can only be flocculated in a small range first and then gradually diffused to the middle of the sludge pool. Therefore, the delivery of flocculants is not uniform and sufficient, and the adsorption time in practice will also be longer, which affects the treatment efficiency of the mixed flocculation treatment system for oily wastewater.

[0004] At the same time, the existing mixed flocculation treatment system for oily wastewater uses flocculants to adsorb and collect in the sludge pool, and then diverts the overflow for treatment. This method is more suitable for oilfield sludge with a small treatment volume and low water content. When faced with oilfield sludge with a large treatment volume or high water content, the treatment effect of flocculant precipitation alone is always limited, which affects the poor treatment effect of the mixed flocculation treatment system for oily wastewater.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] Embodiment 1:

[0029] See also Figure 1-7 In the present embodiment, a sludge flocculation and electro-osmosis combined treatment system comprises a treatment base 1, a sludge pool 2 and an electro-osmosis tank 3. The sludge pool 2 is fixedly provided above one side of the treatment base 1. The sludge pool 2 is a funnel-shaped concrete pit. The interior of the sludge pool 2 is used for flocculation, adsorption and precipitation of oilfield water-containing sludge by flocculants. The electro-osmosis tank 3 is fixedly provided above the other side of the treatment base 1. The electro-osmosis tank 3 is arranged parallel to the sludge pool 2. The interior of the electro-osmosis tank 3 is used for polarization of water (liquid phase) in the soil into a liquid with positive surface charge in the electric field under the action of an external electric field, and moves to a place with low electric potential (cathode). A flocculant uniform injection structure 8 is provided above the sludge pool 2, an electro-osmosis treatment structure 5 is provided on the inner side of the electro-osmosis tank 3, a water-gas separation device 6 is fixedly provided on one end of the treatment base 1, and a waste liquid recovery device 9 is provided inside the other end of the treatment base 1.

[0030] The flocculant uniform injection structure 8 includes a support frame 81 and a flocculant treatment box 85. The support frame 81 is fixedly installed above the sludge pool 2. The support frame 81 is erected horizontally above the sludge pool 2. The top of the support frame 81 is fixedly connected to two vertical poles 82. The vertical poles 82 are used to set the horizontal guide rods 83 above the support frame 81. The inner sides of the two vertical poles 82 are fixedly connected to the guide rods 83.

[0031] The outer wall of the guide rod 83 is slidably connected to a slider 84, and the slider 84 can slide back and forth on the outside of the guide rod 83, so that the flocculant treatment box 85 can slide back and forth above the sludge pool 2. One side of the slider 84 is fixedly connected to the flocculation treatment box 85, and the lower end of the flocculation treatment box 85 is rotatably connected to a plurality of moving wheels 86. The moving wheels 86 can assist the flocculant treatment box 85 to slide horizontally more conveniently, so that the operator can easily push the flocculant treatment box 85 back and forth above the sludge pool 2.

[0032] A flocculant feeding structure 10 is provided on the outside of the flocculation treatment box 85, and the flocculant feeding structure 10 includes a fixed plate 101 and a feeding valve 104. The fixed plate 101 is fixedly connected to one side of the top of the flocculation treatment box 85. The fixed plate 101 is used to set the telescopic replenishing pipe 102 above the feed hopper 103. Under normal circumstances, the telescopic replenishing pipe 102 is made of a corrugated pipe, and the other end is connected to the flocculant raw material position. When the operator can replenish sufficient flocculant into the flocculation treatment box 85 through the telescopic replenishing pipe 102, a feed hopper 103 is fixedly opened at the front end of the flocculation treatment box 85.

[0033] A telescopic replenishing pipe 102 is fixedly connected to the inner side of the fixed plate 101, and the lower end of the telescopic replenishing pipe 102 is arranged opposite to the upper part of the feed hopper 103. When the staff pushes the flocculation treatment box 85 to slide along the upper part of the support frame 81, the two feeding valves 104 at the lower end can be manually opened, and the feeding valves 104 will discharge the flocculant downward along the lower end feeding port 105 by its own gravity. In this way, the flocculant treatment box 85 moving back and forth along the support frame 81 can also uniformly spread the flocculant on the inner side of the sludge pool 2 at the same time. The lower end of the flocculation treatment box 85 is fixedly connected to the two feeding valves 104, and the lowermost ends of the two feeding valves 104 are fixedly connected to the feeding port 105;

[0034] The fixed plate 101 is used to set the telescopic replenishing pipe 102 above the feed hopper 103. Under normal circumstances, the telescopic replenishing pipe 102 is made of a corrugated tube, and the other end is connected to the flocculant raw material position. The operator can replenish sufficient flocculant into the flocculation treatment box 85 through the telescopic replenishing pipe 102.

[0035] When the staff pushes the flocculation treatment box 85 to slide along the top of the support frame 81, the two feed valves 104 at the lower end can be manually opened. The feed valve 104 will discharge the flocculant downward along the lower feeding port 105 using its own gravity. In this way, the flocculant treatment box 85 moving back and forth along the support frame 81 can also simultaneously spread the flocculant evenly on the inner side of the sludge pool 2. In this way, the entire sludge pool can achieve uniform flocculant input in a short time, the flocculant adsorption and purification speed is accelerated, and the working efficiency of the sludge flocculation and electroosmosis combined treatment system is improved.

[0036] The electroosmosis treatment structure 5 includes a filter network 51 and a DC power supply 53. The filter network 51 is fixedly arranged at the inner bottom end of the electroosmosis tank 3. A flat anode 52 is fixedly embedded above the electroosmosis tank 3. The DC power supply 53 is fixedly installed in the middle of the top of the treatment base 1. The front end of the DC power supply 53 is fixedly connected to a positive terminal 54, and the positive terminal 54 is fixedly connected to a first wire 55. The DC power supply 53 is connected to the flat anode 52 above the electroosmosis tank 3 through the positive terminal 54 and the first wire 55. The first wire 55 is connected to the flat anode 52. The front end of the DC power supply 53 is fixedly connected to a negative terminal 56. Similarly, the DC power supply 53 is connected to the flat cathode on the filter network 51 through the negative terminal 56 and the second wire 57.

[0037] A filter pipe net 51 is horizontally laid in the electroosmosis tank 3, and a plane cathode is horizontally laid closely above the filter pipe net 51. The plane cathode and the filter pipe net 51 are buried in the sludge in the electroosmosis tank 3. The negative terminal 56 is fixedly connected to a second wire 57, and the other end of the second wire 57 is connected to the plane cathode above the filter pipe net 51. Through the DC power supply 53, under the action of the electric field, the direct current is used to make the water in the soil flow from the anode to the cathode, thereby reducing the water content of the sludge and improving its physical properties. This process involves the electroosmosis phenomenon, that is, under the action of an external electric field, the water (liquid phase) in the soil is polarized into a liquid with a positive charge on the surface in the electric field, and moves to a place with a low potential (cathode), thereby achieving the effect of discharging the water in the sludge;

[0038] The DC power supply 53 is connected to the plane anode 52 above the electroosmosis tank 3 through the positive terminal 54 and the first wire 55, and the first wire 55 is connected to the plane anode 52. Similarly, the DC power supply 53 is connected to the plane cathode on the filter pipe network 51 through the negative terminal 56 and the second wire 57. The filter pipe network 51 is horizontally laid in the electroosmosis tank 3, and the plane cathode is horizontally laid closely above the filter pipe network 51. The plane cathode and the filter pipe network 51 are both buried in the sludge in the electroosmosis tank 3. Under the action of the electric field, the DC power supply 53 uses direct current to make the water in the soil flow from the anode to the cathode, thereby reducing the water content of the sludge and improving its physical properties. This process involves the electroosmosis phenomenon, that is, under the action of the external electric field, the water (liquid phase) in the soil is polarized into a liquid with a positive charge on the surface in the electric field, and moves to a place with low electric potential (cathode), thereby reaching the point where the water in the sludge is discharged, and the water content in the sludge is further reduced by the electroosmosis principle, thereby improving the treatment effect of the sludge flocculation and electroosmosis combined treatment system.

[0039] The water-gas separation device 6 includes a connecting pipe 61 and a vacuum pump 63. The vacuum pump 63 is fixedly connected to one end above the processing base 1. The top of the vacuum pump 63 is fixedly connected to a water-gas separation tank 62. The other end of the water-gas separation tank 62 is fixedly connected to a connecting pipe 61. The other end of the connecting pipe 61 is connected to the filter pipe network 51.

[0040] The waste liquid recovery device 9 includes a waste liquid pipe 91 and a recovery box 93. The recovery box 93 is fixedly installed on the other side of the top of the processing base 1. A valve switch is provided on the rear side of the recovery box 93 to facilitate the discharge of the recovered waste liquid after opening. The side wall of the recovery box 93 is fixedly connected to the waste liquid pipe 91 through a water pump. The other end of the waste liquid pipe 91 is fixedly connected to one side of the inside of the sludge tank 2. A pump for extracting waste liquid is provided on the other side of the recovery box 93.

[0041] When the other end of the waste liquid pipe 91 is inserted into the middle layer inside the sludge pool 2, when the sludge is discharged into the electro-osmosis tank 3 and only the waste liquid remains to be recycled, the power supply is connected to start the pump so that the filtered waste liquid can pass through the filter layer 92 along the waste liquid pipe 91 and enter the recovery box 93 for storage. The filter layer 92 is fixedly installed at the end of the waste liquid pipe 91. The filter layer 92 adopts a metal steel mesh plate with a certain gap, which can isolate large pieces of debris and garbage inside the sludge pool from entering the recovery box 93.

[0042] A sludge conveying pipe 4 is fixedly installed above the processing base 1. The rear side of the sludge conveying pipe 4 is connected to the source of water-containing sludge generated by oil field excavation, so that the oil field water-containing sludge can be conveyed to the sludge pool 2 for storage and stacking through an external high-power pump. The end of the sludge conveying pipe 4 is arranged opposite to the top of the sludge pool 2.

[0043] Working principle:

[0044] The sludge flocculation and electroosmosis combined treatment system uses flocculants to perform preliminary purification and adsorption treatment of sludge. The function of flocculants is to adsorb particles and "bridge" between particles to promote particle aggregation and sedimentation. For example, commonly used flocculants include polyacrylamide, etc. These flocculants can effectively help suspended matter and colloidal particles aggregate into larger flocs, thereby facilitating subsequent solid-liquid stratification and separation treatment, and then further discharge water through electroosmosis;

[0045] Flocculant distribution and feeding structure of sludge flocculation and electroosmosis combined treatment system:

[0046] The support frame 81 is erected horizontally above the sludge pool 2, and the vertical rod 82 is used to set the horizontal guide rod 83 above the support frame 81. The slider 84 can slide back and forth outside the guide rod 83, so that the flocculant treatment box 85 can slide back and forth above the sludge pool 2. The moving wheel 86 can assist the flocculant treatment box 85 to slide horizontally more conveniently, so that the operator can easily push the flocculant treatment box 85 to move back and forth above the sludge pool 2;

[0047] Flocculant feeding structure of sludge flocculation and electroosmosis combined treatment system:

[0048] The fixed plate 101 is used to set the telescopic replenishing pipe 102 above the feed hopper 103. Under normal circumstances, the telescopic replenishing pipe 102 is made of a corrugated pipe, and the other end is connected to the flocculant raw material position. The operator can replenish sufficient flocculants into the flocculation treatment box 85 through the telescopic replenishing pipe 102. When the staff pushes the flocculation treatment box 85 to slide along the top of the support frame 81, the two feeding valves 104 at the lower end can be manually opened. The feeding valve 104 will discharge the flocculants downward along the lower feeding port 105 by its own gravity. In this way, the flocculant treatment box 85 moving back and forth along the support frame 81 can also evenly spread the flocculants on the inner side of the sludge pool 2 at the same time, so that the entire sludge pool can achieve uniform flocculant input in a short time, and the flocculant adsorption and purification speed is accelerated;

[0049] The electroosmotic treatment structure of the sludge flocculation and electroosmotic combined treatment system:

[0050] The DC power supply 53 is connected to the plane anode 52 above the electroosmosis tank 3 through the positive terminal 54 and the first wire 55, and the first wire 55 is connected to the plane anode 52. Similarly, the DC power supply 53 is connected to the plane cathode on the filter pipe network 51 through the negative terminal 56 and the second wire 57. The filter pipe network 51 is horizontally laid in the electroosmosis tank 3, and a plane cathode is horizontally laid closely above the filter pipe network 51. The plane cathode and the filter pipe network 51 are both buried in the sludge in the electroosmosis tank 3. Under the action of the electric field, the DC power supply 53 uses direct current to make the water in the soil flow from the anode to the cathode, thereby reducing the water content of the sludge and improving its physical properties. This process involves the electroosmosis phenomenon, that is, under the action of the external electric field, the water (liquid phase) in the soil is polarized into a liquid with a positive surface charge in the electric field, and moves to a place with low electric potential (cathode), thereby reaching the point where the water in the sludge is discharged;

[0051] Waste liquid recovery structure of sludge flocculation and electroosmosis combined treatment system:

[0052] A valve switch is provided at the rear side of the recovery box 93, which is convenient for discharging the recovered waste liquid after opening. The other end of the waste liquid pipe 91 is fixedly connected to one side of the interior of the sludge pool 2. A pump for extracting the waste liquid is provided on the other side of the recovery box 93. When the other end of the waste liquid pipe 91 is inserted into the middle layer inside the sludge pool 2, when the sludge is discharged into the electroosmosis tank 3 and only the waste liquid remains to be recovered, the pump is started by connecting the power supply so that the filtered waste liquid can be passed through the filter layer 92 along the waste liquid pipe 91 and enter the recovery box 93 for storage. A filter layer 92 is fixedly installed at the end of the waste liquid pipe 91. The filter layer 92 adopts a metal steel mesh plate with a certain gap, which can isolate large pieces of debris and garbage inside the sludge pool from entering the recovery box 93.

[0053] The rear side of the sludge conveying pipe 4 is connected to the source of the water-containing sludge produced by oil field excavation, so that the water-containing sludge of the oil field can be conveyed to the sludge pool 2 for storage and stacking through an external high-power pump.

[0054] Embodiment 2:

After the sludge in the sludge pool 2 has been treated with flocculant adsorption, the sludge transport pump 71 is started by connecting the power supply. The sludge transport pump 71 can transport the treated sludge in the sludge pool 2 along the sludge transport pipe 72 to the electroosmosis tank 3 for electroosmosis treatment. The sludge transport pump 71 is fixedly connected to the interior of the treatment base 1, and the two planes of the planar anode 52 and the planar cathode above the filter tube network 51 are parallel and arranged correspondingly, and the height of the sludge pool 2 is close to the height of the electroosmosis tank 3.

[0056] Working principle:

[0057] After the sludge in the sludge pool 2 has been treated with flocculant adsorption, the sludge conveying pump 71 is started by connecting the power supply. The sludge conveying pump 71 can convey the treated sludge in the sludge pool 2 to the electroosmosis tank 3 along the sludge conveying pipe 72 to prepare for electroosmosis treatment.
