Description

Technical Field

[0001] The invention relates to the technical field of concentrated liquid reinjection equipment, and in particular to a nanofiltration concentrated liquid reinjection device. Background Art

[0002] At present, with the continuous improvement of environmental protection standards, the coal chemical industry is required to implement stricter environmental protection standards. The high-salt wastewater generated by the coal chemical industry contains not only a large amount of organic pollutants, but also a large amount of inorganic salts. Nanofiltration treatment through nanofiltration membrane can effectively and significantly reduce the concentration of inorganic salts in the wastewater, but the concentrated waste liquid obtained after nanofiltration (i.e., nanofiltration concentrate) still contains a large amount of organic pollutants. Direct discharge into surface water will cause pollution and the death of freshwater organisms; if discharged into the municipal sewage treatment system, it will cause a large number of microorganisms in the biological pool to die and water quality deteriorate, so the nanofiltration concentrate needs to be further treated.

[0003] The existing technology uses evaporation and crystallization to treat nanofiltration concentrate in the coal chemical industry. The evaporation and crystallization method concentrates organic matter and high-salt components. This method will produce a large amount of hazardous waste and impurities, and cannot achieve effective treatment of nanofiltration concentrate, and will cause waste of resources. Therefore, re-injection technology is now mostly used to treat nanofiltration concentrate.

[0004] Nanofiltration concentrate reinjection treatment technology is a technology that treats the concentrated liquid produced in the nanofiltration process and reinjects it into the ground; the nanofiltration concentrate reinjection treatment technology usually includes the following steps: 1. Concentrate collection: collect the concentrated liquid produced in the nanofiltration process and store it in a special container; 2. Pretreatment: pretreat the concentrate, such as adjusting the pH value, removing suspended matter, etc., to improve the subsequent treatment effect; 3. Deep treatment: use physical, chemical or biological methods to deeply treat the concentrate, such as reverse osmosis, electrodialysis, ion exchange, advanced oxidation and other technologies to remove harmful substances in the concentrate; 4. Reinjection: Reinject the treated concentrate into the landfill, usually directly vertically into the landfill, which can effectively remove organic pollutants such as COD (Chemical Oxygen Demand), ammonia nitrogen and total nitrogen in the nanofiltration concentrate, and the nanofiltration concentrate can also promote further degradation of the garbage.

[0005] In the above-mentioned step of reinjecting the nanofiltration concentrate into the landfill, the nanofiltration concentrate is easily affected by the shape, depth, size and other characteristics of different garbage piles in the landfill, which makes the nanofiltration concentrate contact with the garbage in different directions in the garbage pile uneven, and the liquid flow rate of the nanofiltration concentrate entering the garbage pile fluctuates greatly, resulting in the garbage in the garbage pile being unable to contact and react with the nanofiltration concentrate evenly and quickly, which seriously reduces the degradation speed and efficiency of the nanofiltration concentrate and the garbage, and further reduces the efficiency and effect of the nanofiltration concentrate reinjection treatment.

[0035] By setting the compression component 10, the rotation drive component 20 and the nanofiltration component 30 to work together, the automatic compression of the garbage and the automatic reinjection of the nanofiltration concentrate are realized; by setting a plurality of hole-retaining rods 12, the garbage block formed after compression has a plurality of pores inside, so that the nanofiltration concentrate can flow through the plurality of pores inside the garbage block, thereby ensuring the effect of the contact reaction between the inside of the garbage block and the nanofiltration concentrate; the present invention avoids the nanofiltration concentrate being affected by the shape, depth, size and other characteristics of different garbage blocks, so that the nanofiltration concentrate is in uniform contact with the garbage in different directions in the garbage block and the liquid flow rate of the nanofiltration concentrate entering the garbage block is stable, so that the inside of the garbage block is Garbage can be contacted and reacted with nanofiltration concentrate evenly and quickly, which improves the speed and efficiency of nanofiltration concentrate treatment and garbage degradation; by setting the compression cylinder 11 to have an avoidance state and a dumping state, the work of nanofiltration concentrate re-injection of the garbage compressor does not affect each other; the nanofiltration concentrate re-injection device proposed in the present invention can reuse waste resources, not only through physical and chemical effects with garbage, but also through the recycling of nanofiltration concentrate to promote the degradation of garbage waste, which has dual advantages; the present invention has a simple structure and low cost, is easy to assemble and subsequent maintenance, is environmentally friendly and has little pollution, and is suitable for large-scale promotion and use.

[0036] Optionally, in another embodiment of the present invention not shown in the figure, during the garbage compression process, the present invention further provides a perforated plate that cooperates with the perforated rod 12. When compressing the garbage block, the driving element directly applies pressure to the perforated plate to compress the garbage between the perforated plate and the first bottom plate 131 and the second bottom plate 133, and prevents the perforated rod 12 from being bent and damaged due to the force when the garbage is compressed.

[0037] like Figure 2 As shown, the bottom plate structure 13 includes: a first bottom plate 131, a first rotating arm 132, a second bottom plate 133 and a second rotating arm 134, and a plurality of hole-retaining rods 12 are telescopically arranged at intervals on the first bottom plate 131 and the second bottom plate 133; the first rotating arm 132 and the second rotating arm 134 are rotatably arranged on both sides of the compression cylinder 11, the first bottom plate 131 is arranged at one end of the first rotating arm 132, and the second bottom plate 133 is arranged at one end of the second rotating arm 134, and the opening and closing structure 14 is connected to the other end of the first rotating arm 132 and the other end of the second rotating arm 134 respectively; wherein the opening and closing structure 14 simultaneously drives the other end of the first rotating arm 132 and the other end of the second rotating arm 134 to move, driving the first bottom plate 131 and the second bottom plate 133 to rotate simultaneously to open and close the garbage outlet 113; the rotation directions of the first bottom plate 131 and the second bottom plate 133 are opposite.

[0038] By setting the first bottom plate 131 and the second bottom plate 133, the garbage outlet 113 can be effectively closed when the garbage is compressed to prevent the unprocessed garbage from scattering; at the same time, when the garbage block needs to be released, the first bottom plate 131 and the second bottom plate 133 can rotate in the opposite direction to quickly open the garbage outlet 113, so that the garbage block can smoothly enter the nanofiltration chamber 311; this not only improves the efficiency of garbage treatment, but also ensures that the garbage block can completely maintain its internal pore structure, which is beneficial to the penetration of nanofiltration concentrate.

[0039] like Figure 2 and Figure 6 As shown, the opening and closing structure 14 includes a guide frame 141 and a switch part 142. The outer periphery of the compression cylinder 11 is provided with a guide block 114, and the guide block 114 extends in the vertical direction; the guide frame 141 is slidably sleeved on the guide block 114, and is limitedly matched with the guide block 114; the guide frame 141 has an empty groove 143 inside, and the empty groove 143 is respectively slidably limitedly matched with the other end of the first rotating arm 132 and the other end of the second rotating arm 134; the switch part 142 is arranged on the outer periphery of the compression cylinder 11, and is used to lock the guide frame 141; In the embodiment, when the switch portion 142 locks the guide frame 141, the guide frame 141 is fixed, and the first bottom plate 131 and the second bottom plate 133 simultaneously close the garbage outlet 113; when the switch portion 142 releases the guide frame 141, the guide frame 141 moves downward along the guide block 114 under the action of gravity, and the other end of the first rotating arm 132 and the other end of the second rotating arm 134 slide relative to the empty groove 143 respectively and move downward at the same time, driving the first bottom plate 131 and the second bottom plate 133 to rotate in the opposite direction at the same time to open the garbage outlet 113.

[0040] By setting the guide frame 141 and the switch part 142, the bottom plate structure 13 can be automatically controlled. The guide frame 141 fixes the bottom plate structure 13 when the compression cylinder 11 is in the garbage compression state, and automatically slides down under the control of the switch part 142 when the garbage block needs to fall, thereby releasing the bottom plate structure 13. This reduces manual operations, improves the degree of automation of the device, and also ensures the orderly falling of the garbage blocks, preventing garbage blockage and a decrease in processing efficiency.

[0041] like Figure 4 and Figure 6As shown, the switch part 142 includes a positioning block 144 and a plug rod 145. The plug rod 145 is made of magnetic material. The positioning block 144 is fixedly arranged on the outer periphery of the compression cylinder 11, and the plug rod 145 is elastically arranged on the positioning block 144 through a spring; the guide frame 141 has a positioning hole, and the plug rod 145 is inserted into or extended from the positioning hole to lock or release the guide frame 141; the nanofiltration concentrated liquid recharging device also includes a control component 40, which is arranged on the nanofiltration cylinder 31 and is corresponding to the compression component 10; the control component 40 has an electromagnet 41, and in the tilted state, the compression cylinder 11 is in the tilted position. Above the pouring port 312, the electromagnet 41 of the control assembly 40 controls the insertion rod 145 to extend out of the positioning hole through the magnetic force to loosen the guide frame 141. The guide frame 141 moves downward along the guide block 114 under the action of gravity, driving the first bottom plate 131 and the second bottom plate 133 to rotate in the opposite direction at the same time to open the garbage outlet 113; in the avoidance state, the compression cylinder 11 does not block the pouring port 312, and the magnetic force of the electromagnet 41 does not affect the insertion rod 145. The spring drives the insertion rod 145 to extend into the positioning hole to lock the guide frame 141, and the first bottom plate 131 and the second bottom plate 133 close the garbage outlet 113 at the same time.

[0042] By providing the electromagnet 41 and the spring-driven plug 145, precise coordination between the compression component 10 and the nanofiltration component 30 is achieved; when the compression cylinder 11 is in a dumping state, the electromagnet 41 loosens the guide frame 141 through magnetic control of the plug 145, so that the garbage block falls smoothly into the nanofiltration cylinder 31; in the avoidance state, the electromagnet 41 does not affect the plug 145, and the guide frame 141 is kept fixed by the force of the spring, ensuring that the garbage block will not be released prematurely before dumping, thereby improving the consistency and stability of the overall processing flow and reducing energy consumption.

[0044] By setting up a detection controller 43 to detect the position status of the compression cylinder 11 and control the connection between the hook 45 and the swing arm 47, the electromagnet 41 is triggered to operate; this design not only realizes automatic control, but also slows down the movement of the swing arm 47 through the cooperation of the buffer pad 46 and the torsion spring, thereby protecting the stability and durability of the device.

[0045] Optionally, in another embodiment of the present invention not shown in the figure, the sling 44 can also be replaced by a telescopic rod to complete the retraction of the hook 45 and prevent the hook from being stuck due to excessive elastic force of the coil spring at one end of the swing arm 47, resulting in the problem of untimely release of the swing arm.

When the limiting protrusion 221 is located at the first end 212, the compression cylinder 11 is in a tilted state; when the limiting protrusion 221 is located at the second end 213, the compression cylinder 11 is in an avoidance state.

[0049] By setting up the use of the rotating drum 21 and the hydraulic cylinder 24, the compression drum 11 can be rotated smoothly and controllably; through the cooperation between the limiting protrusion 221 and the spiral groove 211, the compression drum 11 can be accurately switched between the dumping state and the avoidance state, ensuring the orderly treatment of the garbage blocks and the smooth injection of the nanofiltration concentrate, thereby improving the treatment efficiency.

[0050] like Figure 2 As shown, the nanofiltration component 30 also includes a drainage funnel 32, which is detachably arranged on the nanofiltration cartridge 31; the drainage funnel 32 has a drainage cavity inside, and the two ends of the drainage funnel 32 are respectively a first port and a second port, the first port and the second port are respectively connected to the drainage cavity, and the second port is connected to the pouring port 312, wherein the caliber of the first port is larger than the caliber of the second port, so as to guide the nanofiltration concentrate into the nanofiltration cavity 311.

[0051] The drainage funnel 32 is provided to facilitate the injection of the nanofiltration concentrate and avoid splashing of liquid droplets, and also ensure that the liquid can evenly cover the garbage blocks, thereby improving the uniformity and efficiency of the treatment; at the same time, the detachable design of the drainage funnel 32 facilitates the maintenance and cleaning of the device.

[0052] like Figure 1 and Figure 2As shown, the nanofiltration cartridge 31 includes a barrel 313, a side cover 314 and a locking block 315. The barrel 313 has a nanofiltration chamber 311 inside, and the upper part of the barrel 313 has a pouring port 312; the barrel 313 also has an operating port on the side wall, which is connected to the nanofiltration chamber 311, and the inner wall of the nanofiltration chamber 311 is cleaned through the operating port; the side cover 314 is detachably arranged on the barrel 313, and is used to open or seal the operating port; the locking block 315 is arranged on the outside of the barrel 313, and is used to fix the side cover 314 on the barrel 313.

[0053] By providing the cylinder 313, the side cover 314 and the locking block 315, it is convenient to clean the inside of the device and to remove and replace the garbage blocks, thereby improving the cleanliness and maintainability of the device; at the same time, the detachable design of the side cover 314 reduces the complexity of the operation and improves the convenience of use of the device.

[0054] like Figure 2 , Figure 4 and Figure 7 As shown, the nanofiltration concentrated liquid reinjection device also includes a waste liquid pool 50, which is arranged at the bottom of the cylinder 313; the bottom of the cylinder 313 is provided with a water-permeable groove 316, which is connected to the bottom of the nanofiltration chamber 311 and the waste liquid pool 50 respectively, and is used to drain the waste liquid at the bottom of the nanofiltration chamber 311 into the waste liquid pool 50, and the waste liquid pool 50 is used to collect waste liquid; wherein, the water-permeable groove 316 extends along the circumference of the cylinder 313, and the size of the water-permeable groove 316 is smaller than the minimum size of the garbage, so as to prevent the garbage in the nanofiltration chamber 311 from entering the waste liquid pool 50.

[0055] By setting up a waste liquid pool 50 for collecting treated waste liquid, the impact of direct discharge of waste liquid on the environment is avoided; the design of the permeable groove 316 ensures that the waste liquid can flow smoothly into the waste liquid pool 50 from the bottom of the nanofiltration chamber 311, while preventing the removal of garbage, ensuring the simultaneous treatment of garbage and waste liquid recovery, improving resource utilization, and reducing the burden on the environment.

[0056] The working process and principle of a specific embodiment of the present invention are now described in detail as follows:

[0057] The present invention provides a compression component 10 to compress garbage, and at the same time, retains pores in the compressed garbage block. After the compression is completed, the control component 40 can keep the garbage block aligned with the cylinder 313 and then fall, thereby ensuring the longitudinal passing capacity of the liquid in the garbage block; when using the compression component 10, the garbage is poured into the compression cylinder 11, and the hole-retaining rod 12 makes the garbage block compacted while retaining a large number of longitudinal passing holes, and the rotation drive component 20 works to drive the compression cylinder 11 to rotate above the cylinder 313. At this time, the insertion rod 145 is retracted into the positioning block 144 under the action of the control component 40, and the retractable hole-retaining rod 12 is retracted from the compressed garbage block. At this time, the garbage block is pressed against the first bottom under the action of gravity. The plate 131 and the second bottom plate 133 apply force, so that the first bottom plate 131 and the second bottom plate 133 have a tendency to rotate along the first rotating arm 132 and the second rotating arm 134. After the rod 145 is received in the positioning block 144, the rod 145 releases the vertical movement restriction on the guide frame 141. At this time, the guide frame 141 will slide vertically along the positioning block 144 under the action of the first rotating arm 132 and the second rotating arm 134 and gravity until the first bottom plate 131 and the second bottom plate 133 are fully opened. At this time, the garbage blocks fall into the cylinder 313 for stacking. Repeat the above operation until the number of garbage blocks in the cylinder 313 meets the re-injection requirements, and finally inject the coal chemical nanofiltration concentrate into the cylinder 313.

[0058] Specifically, in a specific embodiment of the present invention, the present invention can control the falling time of the garbage block by setting a control component 40 to prevent the garbage block from changing its stacking state in the cylinder 313 and affecting the passing effect of the pores. After the garbage is compressed, the lifting rod 23 is driven to descend, and the rotating cylinder 21 will move down synchronously at this time. When the limiting protrusion 221 slides along the spiral groove 211 to the first end 212 of the spiral groove 211, the compression cylinder 11 rotates 180 degrees, and a detection controller 43 is set on the inner side of the vertical plate 42. When the compression is completed, the lifting rod 23 is driven to descend, and the rotating cylinder 21 moves downward synchronously. When the limiting protrusion 221 slides along the spiral groove 211 to the first end 212 of the spiral groove 211, the compression cylinder 11 rotates 180 degrees, and a detection controller 43 is set on the inner side of the vertical plate 42. After the cylinder 11 rotates 180 degrees, the detection controller 43 detects the posture of the compression cylinder 11. When the compression cylinder 11 is aligned with the cylinder body 313, the hanging rope 44 is loosened, and the hook 45 moves downward under the action of gravity until it is disengaged from the clamping device at the bottom of the swing arm 47. At this time, the swing arm 47 will rotate under the elastic force of the coil spring until the swing arm 47 is in contact with the buffer pad 46 of the vertical plate 42, and then the electromagnet 41 on the inner side of the swing arm 47 repels the insertion rod 145, so that the insertion rod 145 is retracted into the positioning block 144, completing the falling of the garbage block.

[0059] Specifically, the permeable groove 316 and the drainage funnel 32 provided in the present invention can guide the coal chemical nanofiltration concentrate to prevent the nanofiltration concentrate from flowing to the outside of the device or accumulating in the cylinder 313 to cause additional pollution. At the same time, a diversion slope is provided on the outside of the cylinder 313. The nanofiltration concentrate can flow to the permeable groove 316 opened on the inside of the cylinder 313, and then flow to the diversion slope provided on the outside, and finally flow into the waste liquid pool 50 under the guidance of the diversion slope.

[0060] In summary, the present invention provides a nanofiltration concentrated liquid reinjection device, which realizes automatic compression of garbage and automatic reinjection of nanofiltration concentrated liquid by setting a compression component 10, a rotation drive component 20 and a nanofiltration component 30 to work together; by setting a plurality of hole-retaining rods 12, the garbage block formed after compression has a plurality of pores inside, so that the nanofiltration concentrated liquid can flow through the plurality of pores inside the garbage block, thereby ensuring the effect of contact reaction between the inside of the garbage block and the nanofiltration concentrated liquid; the present invention avoids the nanofiltration concentrated liquid being affected by the shape, depth, size and other characteristics of different garbage blocks, so that the nanofiltration concentrated liquid contacts the garbage in different directions in the garbage block evenly and the liquid flow rate of the nanofiltration concentrated liquid entering the garbage block is stable, so that the inside of the garbage block Garbage can be contacted and reacted with nanofiltration concentrate evenly and quickly, which improves the speed and efficiency of nanofiltration concentrate treatment and garbage degradation; by setting the compression cylinder 11 to have an avoidance state and a dumping state, the work of nanofiltration concentrate re-injection of the garbage compressor does not affect each other; the nanofiltration concentrate re-injection device proposed in the present invention can reuse waste resources, not only through physical and chemical effects with garbage, but also through the recycling of nanofiltration concentrate to promote the degradation of garbage waste, reuse the useful substances in the concentrate, and improve resource utilization, which has dual advantages; the present invention has a simple structure and low cost, is easy to assemble and subsequent maintenance, is environmentally friendly and has little pollution, and is suitable for large-scale promotion and use.
