Description

Technical Field

[0001] This invention belongs to the field of oil sludge pyrolysis treatment technology, specifically an oil sludge pyrolysis resource utilization treatment device and process flow. Background Technology

[0002] Oily sludge is oily waste and belongs to HW08 category of hazardous waste. It is flammable and toxic, and the toxic substances in oily sludge are difficult to degrade, causing serious harm to the ecology and human health.

[0003] A patent with publication number CN106698881A discloses an oil sludge resource utilization system. The system includes: an oil sludge feeding device (A) with an oil sludge inlet and an oil sludge outlet; a pyrolysis device (B) with an oil sludge inlet, a pyrolysis waste residue outlet, and a pyrolysis steam outlet; a pyrolysis steam cooling device (D) with a pyrolysis steam inlet, a cooling liquid outlet, and a cooling gas outlet; and a tail gas treatment device (E) with a cooling gas inlet and an exhaust port. The oil sludge outlet of the oil sludge feeding device (A) is connected to the oil sludge inlet of the pyrolysis device (B), the pyrolysis steam outlet of the pyrolysis device (B) is connected to the pyrolysis steam inlet of the pyrolysis steam cooling device (D), and the cooling gas outlet of the pyrolysis steam cooling device (D) is connected to the cooling gas inlet of the tail gas treatment device (E). The system provided in this disclosure can recycle oil sludge after vacuum negative pressure pyrolysis treatment.

[0004] In current technologies, the sludge inside oil fields contains a large amount of oily wastewater used to balance oil pressure. When the sludge is mixed with the oily wastewater, it will expand its volume by 2-3 times, thereby increasing the costs of transportation, storage, and disposal. Moreover, when the water content of the sludge is too high, water vapor will directly accumulate inside the furnace, causing the furnace temperature to remain below 350 degrees Celsius, which prevents the sludge from undergoing effective pyrolysis.

[0005] Therefore, the present invention provides an apparatus and process flow for the resource utilization of oil sludge through pyrolysis. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Firstly, the technical solution adopted by the present invention to solve its technical problem is as follows: The oil sludge pyrolysis resource utilization treatment device of the present invention includes a water vapor evaporator and a high-temperature heater fixedly installed on the outer surface of the water vapor evaporator, and a condensation box fixedly installed on the back of the water vapor evaporator. An arc-shaped heating plate detachably installed on the outer surface of the water vapor evaporator is fixedly connected to the output end of the high-temperature heater. The outer surface of the condensation box is fixedly installed on one side surface of the high-temperature heater. A motor is symmetrically fixedly installed on the top surface of the water vapor evaporator and at the two side edges. A transmission rod is fixedly connected to the output end of the motor. Multiple sets of stirring strips are fixedly connected to the outer surface of the transmission rod. The condensation box has two-part differentiation hollow grooves inside. Spiral condensing tubes are fixedly connected to the upper and lower sides of the differentiation hollow grooves. The interior of the differentiation hollow grooves is filled with clean water adhering to the outer surface of the spiral condensing tubes.

[0008] Preferably, a vent pipe is fixedly connected to the top surface of the condenser, and an exhaust fan is fixedly connected to the other end of the vent pipe and installed on the top surface of the water vapor evaporator.

[0009] Preferably, two sets of feed pipes are symmetrically fixedly installed on the outer surface of the water vapor evaporator and at the top edge position. A limiting plate is fixedly connected to the bottom outer surface of the transmission rod. A transmission track is movably sleeved on the outer surface of the transmission rod and at the inner wall of the limiting plate. Multiple sets of interlaced transmission plates are fixedly snapped onto the outer surface of the transmission track. A triangular dividing groove is provided on the outer surface of the interlaced transmission plate and at one edge position.

[0010] Preferably, a support frame is provided on the bottom surface of the water vapor evaporator, a hydraulic rod is fixedly installed on the front of the water vapor evaporator, a limit groove is provided on the front of the water vapor evaporator and on the bottom surface of the hydraulic rod, a closed baffle is fixedly installed on the output end of the hydraulic rod and movably sleeved on the inner wall of the limit groove, and a sludge discharge channel is fixedly installed on the outer surface of the water vapor evaporator.

[0011] Preferably, four sets of circulating water pumps are symmetrically fixedly installed on both sides of the condenser and at the edge of the two-component hollow trough. A filter sponge layer is provided on the bottom inner wall of the condenser, and a drain port is provided on the outer surface of the condenser and at one edge of the filter sponge layer.

[0012] Secondly, a process flow for the resource utilization of oil sludge through pyrolysis includes the following steps: S1. Use a grab bucket to send large pieces of oily sludge into the shredder. After pre-treatment by the shredder, the sludge is discharged and then evaporated through the water vapor evaporation tank. The treated oily sludge is then sent to a temporary storage room to await subsequent calcination treatment. S2. Use a grab bucket to send pre-treated or non-pre-treated small pieces of sludge to the material hopper of the feeding platform, and weigh the sludge using the belt weighing scale inside the material hopper. Send the weighed material to the hydraulic feeder. S3. Meanwhile, some packaged materials are transported by forklift to the loading position of the vertical lift. The vertical lift delivers the materials to the loading platform and then transfers them to the material pile above the hydraulic feeder or belt weigher for stacking. S4. The material is pushed into the rotary kiln by the hydraulic feeder for heating treatment. If the material has a low calorific value, a low calorific value burner is used for heating, and vice versa, a high calorific value burner is used for heating. The exhaust gas is discharged from the corresponding exhaust gas port. S5. The material discharged from the rotary kiln passes through the water extraction tank and is then pulled out by the water extraction chain conveyor and sent into the material pool. After further treatment, it meets the standards for discharge into the natural environment and is then discharged outdoors.

[0013] Preferably, step S2 further includes the following step: The grab bucket is used to deliver pre-treated or non-pre-treated small pieces of material to the hopper of the loading platform; and the belt weighing scale on the bottom surface of the hopper automatically weighs the loose material placed on the belt and continuously passing through the belt, and delivers the material out of the hopper; the belt weighing scale can automatically and continuously measure the bulk solid material conveyed by the belt conveyor, and can measure the instantaneous conveying volume and total cumulative volume passing through the weighing frame; the belt weighing scale delivers the material to the hydraulic feeder.

[0014] Preferably, step S4 further includes the following step: The material is pushed into the rotary kiln by a hydraulic feeder. The kiln has a certain inclination to transport the sludge material. At this time, the high-temperature furnace gas generated when the fuel is produced in the kiln flows in the opposite direction to the flow of the furnace charge. The entire roasting process is divided into three sections: the preheating zone, the roasting reaction zone, and the cooling zone. The material is added from the high end of the kiln, and the slag after combustion is discharged from the bottom end. When the material has a low calorific value, a low calorific value burner is used for heating, and vice versa. The exhaust gas is discharged from the corresponding exhaust gas port.

[0015] Preferably, step S4 further includes the following step: In the rotary kiln, the oily sludge waste sequentially goes through the ignition section, the combustion section, and the burnout section. The high-temperature flue gas generated by combustion enters the secondary combustion chamber for further combustion, and the generated slag is discharged from the system by the slag discharger. The flue gas from the outlet of the secondary combustion chamber sequentially enters the waste heat boiler and the semi-dry quench tower for cooling.

[0016] Preferably, step S4 further includes the following step: The flue gas from the semi-dry quench tower outlet enters the neutralization reaction tower, where acidic gases are neutralized by quicklime and dioxins are adsorbed by activated carbon, both of which are removed to a certain extent. The flue gas then enters a two-stage bag filter to reduce the dust concentration. The flue gas from the bag filter outlet is purified in a two-stage spray absorption tower, where acidic gases, particulate matter, and dioxins are effectively controlled and removed. Under the action of the induced draft fan, the flue gas is discharged into the atmosphere through a chimney, meeting emission standards.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses an oil sludge pyrolysis resource utilization treatment device and process flow, wherein the oil sludge is fed into the interior of a water vapor evaporator through a feed pipe, and the interior of the water vapor evaporator is completely sealed. At this time, a high-temperature heater is used to heat the oil sludge inside the water vapor evaporator through an arc heating plate, so that the interior of the water vapor evaporator is kept at a high temperature of 140°C. At this time, a motor is used to stir the oil sludge inside the water vapor evaporator through a stirring bar on the outer surface of the transmission rod. The flowing oil sludge pushes the high-temperature oil sludge on the inner wall of the water vapor evaporator, and the low-temperature oil sludge is fully mixed with the high-temperature oil sludge. As the temperature of the oil sludge continues to rise, the oil vapor, light oil vapor, and water vapor inside the oil sludge will gradually evaporate from the interior of the oil sludge and accumulate inside the water vapor evaporator. This achieves the effect of heating the oil sludge at high temperature and stirring the heated oil sludge. The dispersed and stirred oil sludge will gradually release the water vapor and oil vapor inside, thereby reducing the moisture content of the oil sludge. 2. The oil sludge pyrolysis resource utilization device and process flow described in this invention involves the following steps: After evaporation, the oil vapor, light oil vapor, and water vapor accumulate inside the water vapor evaporation tank. A blower is used to extract these substances from the tank, and a venting pipe then guides them into the condenser. A spiral condenser tube circulates the oil vapor, light oil vapor, and water vapor. A low-temperature water source inside the hollow tank cools the surface of the spiral condenser tube, allowing the heated oil vapor, light oil vapor, and water vapor to rapidly pass through the tube. The system interacts with the low-temperature water source inside the hollow tank for heat exchange. The oil, gas, light oil, gas, and water vapor that have absorbed heat will gradually liquefy. Later, employees use a special oil and gas collection tank to recover the liquefied oil, gas, light oil, gas, and water vapor. This achieves the goal of filtering out liquid and gas using high temperature, and then condensing and liquefying the oil, gas, light oil, gas, and water vapor through a liquefaction and condensation device for easy collection later. It also reduces the direct emission of evaporated liquid and gas into the air, thus reducing air pollution. After the employees collect the liquefied liquid and gas, they use a filter sponge layer to filter out some oil or sludge particles inside the liquid and gas. 3. The oil sludge pyrolysis resource utilization treatment device and process flow of the present invention, when the two sets of motors rotate the transmission rod, will drive the transmission track on the outer surface of the transmission rod to rotate together with the rotation of the transmission rod. At this time, the two different volumes of the staggered transmission plates on the outer surface of the transmission track can form a scraping state on the oil sludge. As the staggered transmission plates slide continuously inside the oil sludge, the oil sludge on one side of the water vapor evaporator is pushed to the other side, so that the oil sludge in the middle of the water vapor evaporator will move with the movement of the staggered transmission plates, thereby increasing the thorough mixing of the oil sludge inside the water vapor evaporator. It achieves the effect of using the staggered transmission plates to push the oil sludge back and forth under the push of the transmission track, thereby increasing the repeated mixing treatment of the oil sludge. The rotation of the staggered transmission plates and the stirring bar can also effectively reduce the formation of coagulation and coking of oil sludge inside the heating tank.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0022] like Figures 1 to 4 and Figure 6 As shown, an embodiment of the present invention provides an oil sludge pyrolysis resource utilization treatment device, comprising a water vapor evaporator 14 and a high-temperature heater 13 fixedly installed on the outer surface of the water vapor evaporator 14, and a condenser 12 fixedly installed on the back of the water vapor evaporator 14. An arc-shaped heating plate 131, detachably installed on the outer surface of the water vapor evaporator 14, is fixedly connected to the output end of the high-temperature heater 13. The outer surface of the condenser 12 is fixedly installed on one side surface of the high-temperature heater 13. Two sets of feed pipes 141 are symmetrically fixedly installed on the outer surface of the water vapor evaporator 14 at its top edge. Motors 142 are symmetrically fixedly installed on the top surface of the water vapor evaporator 14 at both side edges. A transmission rod 143 is fixedly connected to the output end of the motor 142. Multiple sets of stirring strips 144 are fixedly connected to the outer surface of the transmission rod 143. A gas guide pipe is fixedly connected to the top surface of the condenser 12. 121. A blower 122 is fixedly connected to the other end of the air duct 121 and is installed on the top surface of the water vapor evaporator 14. The condenser box 12 has two-component hollow troughs 123 inside. Spiral condenser tubes 124 are fixedly connected to the upper and lower surfaces of the hollow troughs 123. The hollow troughs 123 are filled with a substance attached to the outer surface of the spiral condenser tubes 124. A air duct 121 is fixedly connected to the top surface of the condenser box 12. A blower 122 is fixedly connected to the other end of the air duct 121 and is installed on the top surface of the water vapor evaporator 14. Four sets of circulating water pumps 125 are symmetrically fixedly installed on the two sides of the condenser box 12 and at the edge of the two-component hollow troughs 123. A filter sponge layer 126 is provided on the inner wall of the bottom of the condenser box 12. A drain port 127 is provided on the outer surface of the condenser box 12 and at one edge of the filter sponge layer 126.

[0023] The oil sludge is fed into the water vapor evaporator 14 through the feed pipe 141, ensuring that the interior of the water vapor evaporator 14 is completely sealed. The high-temperature heater 13 heats the oil sludge inside the water vapor evaporator 14 using the arc-shaped heating plate 131, maintaining the interior of the water vapor evaporator 14 at a constant temperature of 140°C. The motor 142 then stirs the oil sludge inside the water vapor evaporator 14 using the stirring bar 144 on the outer surface of the transmission rod 143. The flowing oil sludge pushes the high-temperature oil sludge on the inner wall of the water vapor evaporator 14, allowing the low-temperature oil sludge to mix thoroughly. As the temperature of the oil sludge continues to rise, the oil vapor, light oil vapor, and water vapor inside the oil sludge gradually evaporate and accumulate inside the water vapor evaporator 14. This achieves the effect of heating the oil sludge at high temperature and stirring it after heating. The dispersed and stirred oil sludge gradually releases the internal water vapor and oil vapor, thereby reducing the moisture content of the oil sludge. The evaporated oil vapor, light oil vapor, and water vapor accumulate inside the water vapor evaporator 14. At this time, the exhaust fan 122 extracts the oil vapor, light oil vapor, and water vapor from inside the water vapor evaporator 14, and the gas guide pipe 121 pumps the oil vapor, light oil vapor, and water vapor into the condenser 12. The spiral condenser 124 circulates the oil vapor, light oil vapor, and water vapor. Meanwhile, the low-temperature water source inside the hollow separator 123 cools the surface of the spiral condenser 124, causing the heated oil vapor, light oil vapor, and water vapor to quickly react with the hollow separator as they pass through the spiral condenser 124. The low-temperature water source inside tank 123 undergoes heat source interaction treatment. The oil vapor, light oil vapor, and water vapor that have absorbed heat will gradually liquefy. Later, employees use a special oil vapor collection tank to recover the liquefied oil vapor, light oil vapor, and water vapor. This achieves the goal of filtering out liquid vapor using high temperature, and then condensing and liquefying the oil vapor, light oil vapor, and water vapor through a liquefaction condensation device, which facilitates later collection and reduces the direct emission of evaporated liquid vapor into the air, thus reducing air pollution. After the employees collect the liquefied liquid vapor, they use the filter sponge layer 126 to filter out some oil stains or oil sludge particles inside the liquid vapor.

[0024] like Figures 1 to 5 As shown, two sets of feed pipes 141 are symmetrically fixedly installed on the outer surface of the water vapor evaporator 14 at the top edge. A limiting plate 145 is fixedly connected to the bottom outer surface of the transmission rod 143. A transmission track 146 is movably sleeved on the outer surface of the transmission rod 143 at the inner wall of the limiting plate 145. Multiple sets of interlaced transmission plates 147 are fixedly snapped onto the outer surface of the transmission track 146. A triangular dividing groove 148 is provided on the outer surface of the interlaced transmission plate 147 at one edge.

[0025] When the two sets of motors 142 rotate the transmission rod 143, they will drive the transmission track 146 on the outer surface of the transmission rod 143 to rotate together with the transmission rod 143. At this time, the two different volumes of the staggered transmission plates 147 on the outer surface of the transmission track 146 can form a scraping state on the sludge. As the staggered transmission plates 147 slide continuously inside the sludge, they push the sludge on one side of the water vapor evaporator 14 to the other side, so that the sludge in the middle of the water vapor evaporator 14 will move with the movement of the staggered transmission plates 147, thereby increasing the thorough mixing of the sludge inside the water vapor evaporator 14. The staggered transmission plates 147, driven by the transmission track 146, make the sludge move back and forth in a staggered manner, thereby increasing the repeated mixing of the sludge. The rotation of the staggered transmission plates 147 and the stirring bar 144 can also effectively reduce the condensation and coking of the sludge inside the heating tank.

[0026] like Figures 1 to 3 As shown, a support frame 11 is provided on the bottom surface of the water vapor evaporator 14, a hydraulic rod a2 is fixedly installed on the front of the water vapor evaporator 14, a limit groove a1 is provided on the front of the water vapor evaporator 14 and on the bottom surface of the hydraulic rod a2, a closed baffle a3 is fixedly installed on the output end of the hydraulic rod a2 and is movably sleeved on the inner wall of the limit groove a1, and a sludge discharge channel a4 is fixedly installed on the outer surface of the water vapor evaporator 14. After the water vapor in the evaporator 14 has evaporated, the hydraulic rod a2 moves the closed baffle a3 upward, causing the sludge inside the evaporator 14 to flow out into the sludge discharge channel a4 under its own gravity. The flow rate and volume of the sludge can be controlled by the opening size of the closed baffle a3, eliminating the need for manual opening by employees to control the amount of sludge conveyed. This avoids the situation where employees might open the opening too large at once, causing a large amount of sludge to be discharged rapidly under its own gravity, resulting in excessive impact on the sludge and preventing its effective recycling. Example

[0027] like Figure 7 As shown, a process flow for the resource utilization of oil sludge through pyrolysis includes the following steps: S1. Use a grab bucket to send large pieces of oily sludge into the shredder. After pre-treatment by the shredder, the sludge is discharged and then evaporated through the water vapor evaporation tank 14. The treated oily sludge is sent to the temporary storage room and awaits subsequent calcination treatment. S2. Use a grab bucket to send pre-treated or non-pre-treated small pieces of sludge to the material hopper of the feeding platform, and weigh the sludge using the belt weighing scale inside the material hopper. Send the weighed material to the hydraulic feeder. S3. Meanwhile, some packaged materials are transported by forklift to the loading position of the vertical lift. The vertical lift delivers the materials to the loading platform and then transfers them to the material pile above the hydraulic feeder or belt weigher for stacking. S4. The material is pushed into the rotary kiln by the hydraulic feeder for heating treatment. If the material has a low calorific value, a low calorific value burner is used for heating, and vice versa, a high calorific value burner is used for heating. The exhaust gas is discharged from the corresponding exhaust gas port. S5. The material discharged from the rotary kiln passes through the water extraction tank and is then pulled out by the water extraction chain conveyor and sent into the material pool. After further treatment, it meets the standards for discharge into the natural environment and is then discharged outdoors.

[0028] like Figure 7 As shown, S2 further includes the following steps: The grab bucket is used to deliver pre-treated or non-pre-treated small pieces of material to the hopper of the loading platform; and the belt weighing scale on the bottom surface of the hopper automatically weighs the loose material placed on the belt and continuously passing through the belt, and delivers the material out of the hopper; the belt weighing scale can automatically and continuously measure the bulk solid material conveyed by the belt conveyor, and can measure the instantaneous conveying volume and total cumulative volume passing through the weighing frame; the belt weighing scale delivers the material to the hydraulic feeder.

[0029] like Figure 7 As shown, S4 also includes the following steps: The material is pushed into the rotary kiln by a hydraulic feeder. The kiln has a certain inclination to transport the sludge material. At this time, the high-temperature furnace gas generated when the fuel is produced in the kiln flows in the opposite direction to the flow of the furnace charge. The entire roasting process is divided into three sections: the preheating zone, the roasting reaction zone, and the cooling zone. The material is added from the high end of the kiln, and the slag after combustion is discharged from the bottom end. When the material has a low calorific value, a low calorific value burner is used for heating, and vice versa. The exhaust gas is discharged from the corresponding exhaust gas port. In the rotary kiln, the oily sludge waste sequentially goes through the ignition section, the combustion section and the burnout section. The high-temperature flue gas generated by combustion enters the secondary combustion chamber for further combustion, and the generated slag is discharged from the system by the slag discharger. The flue gas from the outlet of the secondary combustion chamber sequentially enters the waste heat boiler and the semi-dry quench tower for cooling. The flue gas from the semi-dry quench tower outlet enters the neutralization reaction tower, where acidic gases are neutralized by quicklime and dioxins are adsorbed by activated carbon, both of which are removed to a certain extent. The flue gas then enters a two-stage bag filter to reduce the dust concentration. The flue gas from the bag filter outlet is purified in a two-stage spray absorption tower, where acidic gases, particulate matter, and dioxins are effectively controlled and removed. Under the action of the induced draft fan, the flue gas is discharged into the atmosphere through a chimney, meeting emission standards.

[0030] Working principle: The oil sludge is fed into the water vapor evaporator 14 through the feed pipe 141, making the interior of the water vapor evaporator 14 completely sealed. At this time, the high temperature heater 13 heats the oil sludge inside the water vapor evaporator 14 to the arc heating plate 131, keeping the interior of the water vapor evaporator 14 at a high temperature of 140°. At this time, the motor 142 stirs the oil sludge inside the water vapor evaporator 14 through the stirring bar 144 on the outer surface of the transmission rod 143. The flowing oil sludge pushes the high temperature oil sludge on the inner wall of the water vapor evaporator 14, and makes the low temperature oil sludge and the high temperature oil sludge fully mixed. As the temperature of the oil sludge continues to rise, the oil vapor, light oil vapor and water vapor inside the oil sludge will gradually evaporate from the interior of the oil sludge and accumulate inside the water vapor evaporator 14. This achieves the effect of heating the oil sludge with high temperature and stirring the heated oil sludge. The dispersed and stirred oil sludge will gradually discharge the water vapor and oil vapor inside, thereby reducing the moisture content of the oil sludge. The evaporated oil vapor, light oil vapor, and water vapor accumulate inside the water vapor evaporator 14. At this time, the exhaust fan 122 extracts the oil vapor, light oil vapor, and water vapor from inside the water vapor evaporator 14, and the gas guide pipe 121 pumps the oil vapor, light oil vapor, and water vapor into the condenser 12. The spiral condenser 124 circulates the oil vapor, light oil vapor, and water vapor. Meanwhile, the low-temperature water source inside the hollow separator 123 cools the surface of the spiral condenser 124, causing the heated oil vapor, light oil vapor, and water vapor to quickly react with the hollow separator as they pass through the spiral condenser 124. The low-temperature water source inside tank 123 undergoes heat source interaction treatment. The oil and gas, light oil and gas, and water vapor that have absorbed heat will gradually liquefy. Later, employees use a special oil and gas collection tank to recover the liquefied oil and gas, light oil and gas, and water vapor. This achieves the goal of filtering out liquid and gas using high temperature, and then condensing and liquefying the oil and gas, light oil and gas, and water vapor through a liquefaction condensation device, which facilitates later collection and reduces the direct emission of evaporated liquid and gas into the air, thus reducing air pollution. After the employees collect the liquefied liquid and gas, they use the filter sponge layer 126 to filter out some oil stains or oil sludge particles inside the liquid and gas. When the two sets of motors 142 rotate the transmission rod 143, they will drive the transmission track 146 on the outer surface of the transmission rod 143 to rotate together with the transmission rod 143. At this time, the two different volumes of the staggered transmission plates 147 on the outer surface of the transmission track 146 can form a scraping state on the sludge. As the staggered transmission plates 147 slide continuously inside the sludge, they push the sludge on one side of the water vapor evaporator 14 to the other side, so that the sludge in the middle of the water vapor evaporator 14 will move with the movement of the staggered transmission plates 147, thereby increasing the thorough mixing of the sludge inside the water vapor evaporator 14. The staggered transmission plates 147, driven by the transmission track 146, make the sludge move back and forth, thereby increasing the repeated mixing of the sludge. The rotation of the staggered transmission plates 147 and the stirring bar 144 can also effectively reduce the condensation and coking of the sludge inside the heating tank.
