Description

Technical Field

[0001] The present invention relates to the technical field of resources and environment, and particularly to a resource - harmless treatment device and method with an oil droplet treatment function. Background Technique

[0002] Oil - containing sludge is a waste generated during the production processes of industries such as oil extraction, oil refining, and chemical engineering. It contains a large amount of petroleum substances, as well as components such as sediment and water. If directly discharged or landfilled without treatment, the harmful substances in the oil - containing sludge will seep into the soil, change the physical and chemical properties of the soil, affect the living environment of microorganisms in the soil, reduce soil fertility, and even cause poor growth or death of vegetation, thereby destroying the ecological balance. At the same time, the petroleum resources in the oil - containing sludge will also be wasted, and thus the sustainable utilization of resources cannot be achieved. Therefore, oil - containing sludge needs to be comprehensively treated for resource - harmless treatment.

[0003] In the existing technology, although the existing resource - harmless treatment equipment can comprehensively treat oil - containing sludge to achieve environmental protection and resource recovery during actual use, its effect in water treatment is poor. The main reason is that the conditioning tank cannot break the emulsion film on the surface of all the emulsified oil droplets in the oil - containing sludge entering it. As a result, after the pretreated oil - containing sludge is separated by a three - phase separator, the water obtained contains tiny - sized and emulsification - stable oil droplets. The water mixed with emulsified oil droplets will affect the treatment effect of the water purification equipment, and then reduce the use effect of the resource - harmless comprehensive treatment equipment.

[0004] Therefore, we propose a resource - harmless treatment device and method with an oil droplet treatment function to solve the problems raised in the above - mentioned background technique. Summary of the Invention

[0005] The purpose of the present invention is to provide a resource - harmless treatment device and method with an oil droplet treatment function to solve the problem that the existing resource - harmless treatment equipment has a poor effect in water treatment, which will lead to a reduction in the use effect of the resource - harmless comprehensive treatment equipment and then reduce the use efficiency of the resource - harmless comprehensive treatment equipment.

Then let the oil enter the oil recovery device for purification and recovery, and let the solid enter the pyrolysis furnace for pyrolysis and reduction.

[0016] S2. At the same time, put the residue obtained by pyrolysis into the solidification machine for solidification and stabilization treatment, and then landfill it. At the same time, let the water first enter the demulsification reaction tank for demulsification treatment of the residual emulsified oil droplets, and then let the treated water enter the water purification device for purification treatment, and then discharge it; S3.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the auxiliary mechanism, the present invention can improve the water treatment effect of the resource - harmless treatment device with an oil droplet treatment function, that is, it can treat the emulsified oil droplets mixed in the water separated from the three-phase separator, so as to ensure the water treatment effect of the subsequent water purification device, which not only improves the use effect of the resource - harmless comprehensive treatment device, but also improves the use efficiency of the resource - harmless comprehensive treatment device. When it is necessary to treat the water discharged from the outlet end of the three-phase separator, at this time, by using the cooperation of the control cabinet, another water pump and the corresponding two water pipes, the water discharged from the outlet end of the three-phase separator can be conveyed to the demulsification tank.

[0018] 2. Subsequently, the present invention can realize pumping out the demulsifier liquid in the liquid storage tank and transporting it to the inside of the shunt pipe by using the cooperation of the control cabinet, one of the water pumps, the corresponding two water pipes, one of the first electric valves, the flow sensor, the flow threshold preset in the control cabinet, and the three-way pipe. At the same time, the amount of the demulsifier liquid entering the inside of the shunt pipe is monitored in real time. Then, by using the cooperation of the shunt pipe and the nozzle, the demulsifier liquid transported from the flow sensor can be evenly scattered on the water in the demulsification tank.

[0019] 3. When the amount of the liquid entering the inside of the shunt pipe reaches the flow rate set by the control cabinet, no more demulsifier liquid will be input into the inside of the three-way pipe at this time. At the same time, the control cabinet will use the cooperation of the fan, the two air pipe bodies, and the other first electric valve to realize transporting all the residual demulsifier liquid inside the three-way pipe, the shunt pipe, the flow sensor, and all the nozzles to the demulsification tank. Then, by using the cooperation of the control cabinet, the generator, and the transducer, the demulsifier and the emulsified oil droplets in the water can be fully contacted, and then the emulsified oil droplets can be converted into free oil droplets.

[0020] 4. By setting the treatment mechanism, the present invention can realize the comprehensive treatment of oily sludge for resource utilization and harmlessness. When it is necessary to treat the oily sludge, first, by using the cooperation of the conditioning tank and chemical agents such as demulsifier and flocculant in appropriate proportions, the chemical conditioning operation of the oily sludge can be realized. Then, by using the cooperation of the opened manual valve, the cam rotor pump, and the two conveying pipes, the conditioned oily sludge inside the conditioning tank can be pumped away and transported to the inside of the three-phase separator. Then, by using the cooperation of the three-phase separator, the conditioned oily sludge can be split into three phases: oil, water, and solid.

[0021] 5. When it is necessary to purify and recover the oil discharged from the oil outlet end of the three-phase separator, at this time, by directly using the cooperation of the control cabinet, the oil pump, the two oil pipes, and the oil recovery treatment equipment, the oil from the oil outlet end of the three-phase separator can be transported to the oil recovery equipment for purification treatment. When it is necessary to carry out solidification and stabilization treatment on the solid waste discharged from the discharge end of the three-phase separator, at this time, by directly using the cooperation of the control cabinet, the pyrolysis furnace, the solidifying machine, and additives such as cement and lime in appropriate proportions, the solid waste discharged from the discharge end of the three-phase separator can be pyrolyzed first and then solidified.

[0022] 6. When the water discharged from the water outlet end of the three-phase separator undergoes preliminary treatment operations, at this time, by directly using the cooperation of the control cabinet, two connecting pipes, a centrifugal pump, and a water purification device, the water entering the second electric valve can be pumped away and purified. When the oil recovery device is performing oil purification treatment and the pyrolysis furnace is performing solid waste pyrolysis operations, both generate tail gas that needs to be treated. At this time, by directly using the cooperation of the three gas collecting pipes, the tail gas pipe, and the tail gas treatment device, the position of the tail gas transported to the interior of the tail gas treatment device can be disposed of.

The placement table 303 and the liquid storage tank 310 are both placed on the top of the base 1. The water inlet end of the shunt pipe 312 movably penetrates through the bottom of the top cover 306. Each nozzle 313 and the two fixing rings 311 are both inside the demulsification tank 305. The water outlet end of the water pipe 302 installed at the water outlet end of one of the water pumps 301 is connected to the output end of one of the first electric valves 316. The water inlet end of the water pipe 302 installed at the water inlet end of one of the water pumps 301 is connected to the water outlet end of the liquid storage tank 310.

[0027] In this embodiment, when it is necessary to treat the water discharged from the water outlet end of the three-phase separator 205, another water pump 301 is directly started by using the control cabinet 216 at this time. The started water pump 301 will, with the cooperation of the corresponding two water pipes 302, directly transport all the water discharged from the three-phase separator 205 into the internal of the demulsification tank 305.

[0029] In this embodiment, when treating oily sludge, first connect the control cabinet 216 to an external power supply. Then, put the oily sludge into the internal of the conditioning tank 201, and at the same time, put chemical agents such as demulsifiers and flocculants in appropriate proportions into the internal of the conditioning tank 201. Then, use the control cabinet 216 to start the conditioning tank 201, so that the oily sludge is fully mixed with the chemical agents inside the conditioning tank 201 for chemical conditioning. When the oily sludge completes the conditioning operation, use the control cabinet 216 to close the conditioning tank 201. Then, open the manual valve 202, and at the same time, use the control cabinet 216 to start the cam rotor pump 203. The started cam rotor pump 203 will pump out the conditioned oily sludge in the conditioning tank 201 through the cooperation of two delivery pipes 204 and the manual valve 202 and transport it to the internal of the three-phase separator 205. When there is no more oily sludge to be pumped out from the internal of the conditioning tank 201, use the control cabinet 216 to close the cam rotor pump 203. Then, use the control cabinet 216 to start the three-phase separator 205. The started three-phase separator 205 will split the conditioned oily sludge into three phases: oil, water, and solid, and then discharge them from the corresponding outlets respectively. When it is necessary to purify and recover the oil discharged from the oil outlet end of the three-phase separator 205, directly use the control cabinet 216 to start the oil pump 206. The started oil pump 206 will directly transport it to the internal of the oil recovery equipment 208 through the cooperation of two oil pipes 207. When no oil enters the internal of the oil recovery equipment 208, directly use the control cabinet 216 to close the oil pump 206. Then, start the oil recovery equipment 208 for purification and recovery, and then collect the purified oil. When it is necessary to carry out solidification and stabilization treatment on the solid waste discharged from the discharge end of the three-phase separator 205, directly send all the solid waste discharged from the discharge end of the three-phase separator 205 into the pyrolysis furnace 218. Then, the control cabinet 216 starts the pyrolysis furnace 218, that is, uses the high-temperature heating of the pyrolysis furnace 218 to pyrolyze and reduce the solid waste. Then, put all the residues after the pyrolysis of the solid waste into the internal of the solidifying machine 217, and at the same time, put additives such as cement and lime in appropriate proportions into the internal of the solidifying machine 217. After that, the control cabinet 216 starts the solidifying machine 217, so that all the substances in the solidifying machine 217 are fully mixed together to undergo a chemical reaction to form a solidified body. Then, take out the formed solidified body from the internal of the solidifying machine 217 and then landfill it. At the same time, when the oil recovery equipment 208 is carrying out oil purification treatment, tail gas will also be generated. When the pyrolysis furnace 218 is carrying out solid waste pyrolysis operation, tail gas will also be generated. And these tail gases will be directly transported to the tail gas treatment equipment 212 through the cooperation of three gas collecting pipes 210 and the tail gas pipe 211, and then be purified and treated. Finally, the treated tail gas (meeting the standards) will be discharged into the environment. When the water completes the preliminary demulsification treatment, directly use the control cabinet 216 to open the second electric valve 319 and start the centrifugal pump 214At this time, the centrifugal pump 214 that is started will, in cooperation with the two connecting pipes 215 and the opened second electric valve 319, directly pump out the water that has been preliminarily treated inside the demulsification tank 305 and transport it to the water purification device 213. When the preliminarily treated water enters the interior of the water purification device 213, at this time, the water purification device 213 will further treat the water, and then discharge the qualified water.

[0030] The effects achieved and working principle of the entire mechanism are as follows: When treating oily sludge, first connect the control cabinet 216 to an external power supply. Then put the oily sludge into the conditioning tank 201, and at the same time put chemical agents such as demulsifiers and flocculants in appropriate proportions into the conditioning tank 201. Next, use the control cabinet 216 to start the conditioning tank 201, so that the oily sludge is fully mixed with the chemical agents inside the conditioning tank 201 for chemical conditioning. When the oily sludge completes the conditioning operation, use the control cabinet 216 to close the conditioning tank 201. Then open the manual valve 202, and at the same time use the control cabinet 216 to start the cam rotor pump 203. The started cam rotor pump 203 will, through the cooperation of the two delivery pipes 204 and the manual valve 202, pump out the conditioned oily sludge in the conditioning tank 201 and transport it to the inside of the three-phase separator 205. When there is no more oily sludge to pump out from the conditioning tank 201, use the control cabinet 216 to turn off the cam rotor pump 203. Then use the control cabinet 216 to start the three-phase separator 205. The started three-phase separator 205 will separate the conditioned oily sludge into three phases: oil, water, and solid, and then discharge them from the corresponding outlets respectively. When it is necessary to purify and recover the oil discharged from the oil outlet end of the three-phase separator 205, directly use the control cabinet 216 to start the oil pump 206. The started oil pump 206 will, with the cooperation of the two oil pipes 207, directly transport it to the inside of the oil recovery device 208. When there is no oil entering the inside of the oil recovery device 208, directly use the control cabinet 216 to turn off the oil pump 206. Then start the oil recovery device 208 for purification and recovery, and then collect the purified oil. When it is necessary to carry out solidification and stabilization treatment on the solid waste discharged from the discharge end of the three-phase separator 205, directly send all the solid waste discharged from the discharge end of the three-phase separator 205 into the pyrolysis furnace 218. Then use the control cabinet 216 to start the pyrolysis furnace 218, that is, use the high-temperature heating of the pyrolysis furnace 218 to reduce the amount of the solid waste by pyrolysis. Then put all the residues formed after the pyrolysis of the solid waste into the inside of the solidifying machine 217, and at the same time put additives such as cement and lime in appropriate proportions into the inside of the solidifying machine 217. After that, use the control cabinet 216 to start the solidifying machine 217, so that all the substances in the solidifying machine 217 are fully mixed together to undergo a chemical reaction to form a solidified body. Then take out the formed solidified body from the inside of the solidifying machine 217 and landfill it. At the same time, when the oil recovery device 208 is carrying out oil purification treatment, it will also generate tail gas. When the pyrolysis furnace 218 is carrying out solid waste pyrolysis operation, it will also generate tail gas. And these tail gases will be directly transported to the tail gas treatment device 212 through the cooperation of the three gas collecting pipes 210 and the tail gas pipe 211, and then be purified and treated. Finally, the treated tail gas (meeting the standards) will be discharged into the environment. When it is necessary to treat the water discharged from the water outlet end of the three-phase separator 205,At this time, directly use the control cabinet 216 to start another water pump 301. The started water pump 301, in cooperation with the corresponding two water pipes 302, will directly transport all the water discharged from the three-phase separator 205 into the interior of the demulsification tank 305. When no water enters the interior of the demulsification tank 305, directly use the control cabinet 216 to turn off another water pump 301. Then, turn on the flow sensor 314, set the flow threshold (set according to the actual situation), one of the first electric valves 316, and one of the water pumps 301. At the same time, use the generator 317 (set an appropriate frequency according to the actual situation) to start all the transducers 318. The started water pump 301, in cooperation with the corresponding two water pipes 302, will first extract the demulsifier liquid from the liquid storage tank 310, then transport it into the interior of the opened first electric valve 316, then into the interior of the tee 315, and then into the interior of the flow sensor 314. When the liquid passes through the interior of the flow sensor 314, the flow sensor 314 will record it in real time and transmit the flow data recorded each time to the control cabinet 216 in the form of an electrical signal. The liquid passing through the interior of the flow sensor 314 will enter the interior of the shunt pipe 312, then be shunted into the interior of each spray head 313, and then evenly sprayed into the water in the interior of the demulsification tank 305. At this time, the ultrasonic waves generated by all the started transducers 318 will make the water and the demulsifier liquid in the demulsification tank 305 fully mixed, that is, use the demulsifier liquid to convert the residual emulsified oil droplets in the water into free oil droplets. When the flow data received by the control cabinet 216 is the same as the flow threshold preset by the control cabinet 216, at the same time, the control cabinet 216 will close one of the first electric valves 316 and one of the water pumps 301, then start the fan 307 and open the other first electric valve 316. The started fan 307, in cooperation with the filter mesh 308, will first filter and then inhale the air in the environment, then transport it into the interior of the air pipe body 309, then into the interior of the opened other first electric valve 316, and then into the interior of the tee 315. That is, use the continuously entering air into the interior of the tee 315 to transport all the residual demulsifier liquid in the tee 315, the shunt pipe 312, the flow sensor 314, and all the spray heads 313 into the demulsification tank 305. When the fan 307 has been started for a period of time, directly use the control cabinet 216 to turn off the fan 307, the other first electric valve 316, and the generator 317. Then, use the control cabinet 216 to open the second electric valve 319 and start the centrifugal pump 214. The started centrifugal pump 214, in cooperation with the two connecting pipes 215 and the opened second electric valve 319, will directly extract the preliminarily treated water in the interior of the demulsification tank 305 and transport it to the water purification device 213. When the preliminarily treated water enters the interior of the water purification device 213, the water purification device 213 will further treat the water, and then discharge the qualified water. That is, through the coordinated operation of the components of the entire comprehensive treatment device,It can realize the resource utilization and harmless treatment of oily sludge.
