Description

Technical Field

[0001] This utility model relates to the field of oil-based rock debris oily sludge treatment technology, specifically a tailings recovery device. Background Technology

[0002] Oil-based cuttings are rock particles ground or crushed by drill bits during oil and shale gas drilling, and are waste products brought to the surface along with oil-based drilling fluid. Oil-based drilling cuttings, oily sludge from oil tanks, and oily sludge accumulated in oil sludge ponds contain pollutants such as petroleum hydrocarbons, heavy metals, and organic matter. If not treated promptly, they can cause serious pollution to the surrounding soil and groundwater, and must be treated through reduction, harmlessness, and resource recovery. Currently, the most widely used treatment method for oil-based rock cuttings and oily sludge is thermal phase separation (including thermal desorption, thermal cracking, thermal drying, etc.). Through heating and auxiliary means, the evaporable part of the target material is separated. Then, the separated vapor is condensed and recovered. The oil and water in the vapor are separated by sedimentation and collected separately. The remaining non-condensable gas is returned to the combustion chamber as auxiliary fuel. After the oil content of the treated solid tailings meets the environmental protection requirements, it is discharged by the discharge device and can be used as reducing soil for oilfield paving, highway construction, or as a building material for comprehensive utilization.

[0003] The tailings discharged from thermal phase separation devices such as thermal desorption furnaces and dry distillation pyrolysis furnaces are generally 300℃-400℃ and must be cooled down to about 100℃. Since the high-temperature tailings contain some high-temperature oil vapor, they are prone to combustion and explosion when exposed to oxidizing media such as air. Therefore, direct cooling with oxidizing media such as air is not advisable. Existing tailings cooling devices generally use rotary coolers and jacketed circulating water to indirectly cool the high-temperature tailings. In the actual cooling process, after the high-temperature tailings just exiting the discharge port enter the rotary cooler, the oil vapor in the tailings condenses and mixes with the tailings to form oil sludge, which adheres to the inner wall of the rotary cooler. This severely reduces the heat transfer efficiency of the cooler, resulting in the tailings discharged from the rotary cooler still having a high temperature. Tailings with excessively high temperatures will affect subsequent conveying and recycling equipment. Conversely, conveying them to the material yard for natural accumulation and cooling not only prolongs the working cycle of tailings recycling and transportation and delays the overall efficiency of oily sludge treatment, but also occupies space and causes dust pollution due to wind.

[0004] Chinese patent document CN219934406U discloses a cooling treatment system for oil-based rock cuttings distillation residue. The system includes a mixer and a cooling water supply system. One end of the mixer is provided with a dry residue inlet and a cooling water inlet, and the other end is provided with a steam outlet and a dry residue outlet. The cooling water supply system is connected to the cooling water inlet. The cooling water supply system sends cooling water into the mixer from the cooling water inlet. After the water fully contacts and evaporates in the mixer, it flows out from the steam outlet. The high-temperature dry residue enters the mixer from the dry residue inlet and is cooled down by fully contacting the cooling water before being sent out from the dry residue outlet. Although the above-mentioned cooling device directly cools the high-temperature dry slag through water evaporation and heat absorption, and its cooling efficiency is better than that of the indirect cooling rotary cooler, the following problems exist in actual use: 1. Because the dry slag inlet and the cooling water inlet are located on the upper left side of the agitator, and the steam outlet is located on the upper right side of the agitator, and the agitator is a relatively closed horizontal cylinder, the dry slag will accumulate in the lower part of the agitator cavity and cannot be spread out flat. The heat of the dry slag in the accumulation center is relatively difficult to dissipate. At the same time, the steam generated by the high-temperature dry slag in the left side of the agitator cavity cannot be discharged from the steam outlet in time. When the steam in the left side of the cavity reaches saturation, it will no longer absorb heat, resulting in low overall cooling efficiency of the equipment; 2. Because the heat dissipation path of the high-temperature dry slag in the agitator is short, the dry slag reaches the dry slag outlet on the right side of the agitator before it has been sufficiently cooled, resulting in the tail slag still having a high temperature when it leaves the dry slag outlet; 3. The tail slag outlet of the equipment is located low, and it needs to be transported to the packaging device for packaging or loading and transporting by other conveying devices, which poses problems of occupying space and causing dust pollution. In addition, the existing tailings cooling device has a horizontally placed cylinder as the agitator, which makes it difficult to clean the accumulated tailings inside after shutdown. Summary of the Invention

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1:

[0020] As attached Figure 1As shown, this utility model provides a tailings recycling device, including a frame 1, a cooling chamber 2, a cooling hopper 3, a cooling conveying device 4, a cooling water supply device 5, a dust removal device 6, a vertical frame 7, a slag storage bin 8, and a discharge device 9. A cooling hopper 3 is fixedly installed on the upper left side of the frame 1, and a cooling hopper outlet 301 is provided at the lower end of the cooling hopper 3. A cooling conveying device 4, capable of conveying high-temperature tailings to the upper right, is fixedly installed on the upper right side of the frame 1. The cooling conveying device 4 includes an L-shaped chain frame 401 and an outer conveyor belt. The scraper chain of the scraper 402 is mounted on the L-shaped chain frame 401, forming a flat section 403 and an inclined section 404. The flat section 403 is arranged approximately horizontally, while the inclined section 404 is arranged inclined from left to right. The left side of the flat section 403 extends below the cooling hopper outlet 301, and the right end of the flat section 403 is connected to the left end of the inclined section 404. A cooling chamber 2 is provided above the cooling hopper 3 and the cooling conveying device 4, and a tailings inlet 2 is provided on the left side of the cooling chamber 2. 01 is equipped with a fixed feed guide 202. The right end of the feed guide 202 can be connected to the tailings inlet of the oil-based rock cuttings thermal phase separation device. The right end of the feed guide 202 is connected to the inner cavity of the cooling chamber 2 through the tailings inlet 201. The cooling hopper 3 is located below the tailings inlet 201. The inner cavity of the cooling chamber 2 above the cooling hopper 3 is equipped with a hopper water mist cooling pipe 10. The hopper water mist cooling pipe 10 is located above the tailings inlet 201. Correspondingly, a conveyor frame water mist cooling pipe 11 is provided above the cooling conveying device 4. A tailings outlet 203 is provided on the cooling chamber 2 located at the lower right end of the cooling conveying device 4. The cooling water supply device 5 is connected to the water mist cooling pipe 10 of the hopper and the water mist cooling pipe 11 of the conveying frame. A steam outlet 204 is provided at the upper end of the cooling chamber 2 and a dust removal device 6 is installed. A vertical frame 7 is provided below the tailings outlet 203. A slag storage bin 8 is fixedly installed on the upper part of the vertical frame 7. A discharge device 9 is fixedly installed on the vertical frame 7 below the slag storage bin 8. A packaging device 12 and a parking space for transport vehicles are provided below the discharge device 9.The feed guide trough 202 can connect to the tailings inlet of the oil-based rock cuttings thermal phase separation device and isolate the high-temperature tailings from the air. The high-temperature tailings are introduced into the cooling hopper 3 through the tailings inlet 201. The water mist cooling pipe 10 in the hopper initially cools the high-temperature tailings in the cooling hopper 3. The cooling water evaporates and absorbs a large amount of heat from the tailings. After contacting the cooling water, the high-temperature tailings fall from the cooling hopper outlet 301 and are evenly spread on the chain belt flat section 403. They are then uniformly conveyed by the conveying scraper 402 on the scraper chain to the upper end of the chain belt inclined section 404. At the same time, the water mist cooling pipe 11 of the conveyor frame further cools the high-temperature tailings on the chain belt flat section 403 and the chain belt inclined section 404. The high-temperature tailings are directly cooled by the evaporation and heat absorption of the cooling water. When it falls onto the flat section 403 of the chain conveyor, it tumbles and is evenly spread, which can effectively prevent the accumulation of high-temperature tailings. During the conveying process, the long scraper chain conveyor is simultaneously cooled evenly again by the water mist cooling pipe 11 of the conveyor frame. The water vapor formed can be discharged in time from the steam outlet 204. The evaporated water vapor carries dust and a small amount of oil mist into the steam outlet 204 at the upper end of the cooling chamber 2, where it is removed by the dust removal device 6. The cooled tailings enter the slag storage bin 8 and are transported to the packaging device 12 or transport vehicle through the discharge device 9. This effectively solves the problems of tailings accumulating in the agitator and not dissipating heat, water vapor not being able to be discharged in time, resulting in the tailings still having a high temperature after processing, low cooling efficiency, and the inability to pack or load the tailings immediately.

[0021] Example 2:

[0022] As attached Figure 1As shown, the difference between this embodiment and Embodiment 1 is that the cooling conveying device 4 further includes a left chain belt shaft 406, a right chain belt shaft 407, and an upper chain belt shaft 408. An L-shaped chain belt frame 401 is fixedly installed on the frame 1. The L-shaped chain belt frame 401 includes a chain belt crossbeam 4011 and a chain belt inclined frame 4012. The chain belt crossbeam 4011 is arranged approximately horizontally, while the chain belt inclined frame 4012 is arranged with a left-lower, right-higher inclination. The right end of the chain belt crossbeam 4011 is fixed to or connected to the lower end of the chain belt inclined frame 4012. A support grid plate 405 is fixedly installed above the chain belt crossbeam 4011. The chain belt flat section 403 is located at the upper end of the support grid plate 405 and can slide to the right along the upper end of the support grid plate 405. The left chain belt shaft 406 is located at the left end of the chain belt crossbeam 4011, and the right chain belt shaft 407 is located at the right end of the chain belt crossbeam 4011. The upper chain belt... The belt shaft 408 is located at the upper end of the chain belt inclined frame 4012. The upper right end of the chain belt cross frame 4011 is provided with a chain belt tensioning wheel 409. The scraper chain belt is installed on the left chain belt shaft 406, the right chain belt shaft 407, and the upper chain belt shaft 408 and is tensioned by the chain belt tensioning wheel 409. The scraper chain belt above the chain belt cross frame 4011 forms a chain belt flat section 403. The scraper chain belt to the left of the chain belt inclined frame 4012 forms a chain belt inclined section 404. The material conveyor water mist cooling pipe 11 includes a cooling horizontal pipe section and a cooling inclined pipe section. The cooling horizontal pipe section and the cooling inclined pipe section are fixedly installed on the chain belt cross frame 4011 and the chain belt inclined frame 4012 respectively by the frame rod. The cooling horizontal pipe section is located above the chain belt flat section 403 and is arranged parallel to the chain belt flat section 403. The cooling inclined pipe section is located above the chain belt inclined section 404 and is arranged parallel to the chain belt inclined section 404. The chain belt flat section 403 can be arranged horizontally, or the right end can be slightly raised at a small angle and arranged approximately horizontally. This allows the cooling water sprayed from the high-temperature tailings on the upper layer of the chain belt flat section 403 to flow to the left side of the chain belt flat section 403, so that the high-temperature tailings can come into contact with the cooling water more and cool down as quickly as possible. The cooling horizontal pipe section and cooling inclined pipe section of the water mist cooling pipe 11 of the conveyor frame are arranged parallel to the chain belt flat section 403 and the chain belt inclined section 404 of the cooling conveyor device 4, respectively, to increase the cooling area of ​​the high-temperature tailings and effectively spray water to cool the high-temperature tailings on the scraper chain belt.

[0023] Example 3:

[0024] As attached Figure 1As shown, the difference between this embodiment and embodiments 1 and 2 is that the cooling water supply device 5 includes a water storage tank 501, a booster pump 502, and a water supply vertical pipe 503. The water storage tank 501 and the booster pump 502 are located outside the cooling chamber 2. The water supply vertical pipe 503 is fixedly installed on the left side of the inner cavity of the cooling chamber 2. The inlet of the booster pump 502 is connected to the water storage tank 501 through a pipeline. The outlet of the booster pump 502 is connected to the hopper water mist cooling pipe 10 and the conveyor frame water mist cooling pipe 11 through the water supply vertical pipe 503 respectively. Atomizing nozzles are evenly spaced at the bottom of the hopper water mist cooling pipe 10 and the conveyor frame water mist cooling pipe 11. The booster pump 502 delivers cooling water from the water storage tank 501 to the atomizing nozzles of the hopper water mist cooling pipe 10 and the conveyor frame water mist cooling pipe 11 through the water supply riser pipe 503. Utilizing the high latent heat of water vaporization, the high-temperature tailings are directly cooled by absorbing heat through water evaporation. This method has the effect of using less water and only requiring a small amount of water to cool the slag. At the same time, it consumes less power, does not require high-power rotary equipment, and does not require a large amount of circulating cooling water, thus significantly reducing power consumption and greatly reducing the operating cost of the equipment.

[0025] Example 4:

[0026] As attached Figure 1 As shown, the difference between this embodiment and embodiments 1-3 is that a heat exchanger 13 is provided between the steam outlet 204 and the dust removal device 6. The steam outlet 204 is connected to the cold source inlet end of the heat exchanger 13, and the cold source outlet end of the heat exchanger 13 is connected to the lower port of the dust removal device 6. A steam discharge pipe 14 is fixedly installed on the upper port of the dust removal device 6. The heat exchanger 13 is provided with several horizontally arranged heat exchange tubes. The left and right sides of the heat exchanger 13 are the heat source inlet and the heat source outlet, respectively. The heat source inlet can be connected to the high-temperature flue gas pipe 15 of the oil-based rock cuttings thermal phase separation device, and the heat source outlet can be connected to the flue gas fan 16 of the oil-based rock cuttings thermal phase separation device. The high-temperature flue gas from the oil-based rock debris thermal phase separation device is used by heat exchanger 13 to heat the steam discharged from steam outlet 204, raising the steam temperature from 100°C to 200°C. This ensures that the oil mist is completely vaporized, preventing it from sticking to or clogging the dust removal device 6 above. The heated dust-laden steam enters the dust removal device 6, where the dust-laden gas is filtered to trap the dust. Under the influence of gravity, the dust falls from the cold source outlet end of heat exchanger 13 through the cold source inlet end and steam outlet 204 onto the inclined section 404 of the chain belt in the lower cooling chamber 2. Together with the tailings, the dust is sent from the inclined section 404 of the chain belt through the tailings outlet 203 into the slag storage bin 8, resulting in better performance.

[0027] Example 5:

[0028] As attached Figure 1As shown, the difference between this embodiment and embodiments 1-4 is that the top of the slag storage bin 8 is provided with a bin inlet 801 and a bin exhaust port 802. A dust collector is provided at the top of the bin exhaust port 802. The tail slag outlet 203 of the cooling chamber 2 is connected to the inner cavity of the slag storage bin 8 through the bin inlet 801. The bottom of the slag storage bin 8 is provided with a bin outlet 803 and is connected to the upper inlet of the discharge device 9. The lower part of the discharge device 9 is provided with a first material pipe 901 and a second material pipe 902.

A loading port is provided on the upright body 7 corresponding to the lower end of the second material pipe 902. The lower end of the second material pipe 902 is connected to the loading port. The parking space for the transport vehicle is located below the loading port. The discharge device 9 enables switching between bagging and loading discharge methods. The transport vehicle is equipped with a sealed box, and the top of the sealed box has a feed inlet. The loading port can be connected to the feed inlet of the sealed box through a telescopic joint, making it more convenient and faster to transfer the tailings in the slag storage bin 8 via the transport vehicle.

[0029] Example 6:

[0030] As attached Figure 1 , 2 As shown, the difference between this embodiment and embodiments 1-5 is that the lower part of the cooling conveying device 4 is provided with a conveying housing, and the lower left part of the conveying housing is provided with a cleaning port with a cleaning door 17. The lower end of the cleaning door 17 is hinged to the lower left end of the conveying housing through a hinge shaft 1701, and the upper end of the cleaning door 17 is fixedly installed on the upper left part of the conveying housing through a quick connection locking device. The quick connection locking device is a horizontal quick clamp 1702 or a quick buckle.
