Description

Technical Field

[0001] The invention relates to the field of industrial waste treatment equipment, and more specifically to a waste emulsion sludge treatment equipment. Background Art

[0002] Emulsion is a high-performance semi-synthetic metal processing liquid. Its main components include water, mineral oil, surfactants, extreme pressure additives, etc. It is suitable for the processing of metals and their alloys, and is used to solve problems such as chip adhesion, tool wear, and surface contamination of workpieces during processing. Emulsion will inevitably deteriorate during long-term use, producing sediment or sludge and other substances, and produce odors that spread throughout the workshop, affecting the workshop operating environment. Since waste emulsion sludge has a certain viscosity, odor, is toxic and flammable, it is a hazardous waste and therefore needs to be handled with caution.

[0003] At present, a few companies are trying to filter the waste emulsified liquid slag and send it to the boiler system for combustion. However, since the fuel contains solid slag and is very viscous, the feeding system is prone to blockage and wear, and the combustion is incomplete. Most companies use chemical methods to break the emulsion. This treatment method requires special equipment and processes, is very costly, and will produce a large amount of sewage, causing secondary pollution.

[0004] After searching, the Chinese patent publication number is: CN104962305A, and the publication date is: October 7, 2015. It discloses a production process for making briquette coal from emulsion waste oil sludge and coking system dust ash. Coking coal is intercepted from a belt conveyor sent to a coke oven coal tower, and 14-17% of emulsion waste oil sludge, 16-20% of coking system dust ash, and 65-68% of coking coal are sent to a primary mixer for stirring. The stirred materials are sent to a secondary mixer for stirring. The secondary stirred materials are sent to a buffer bin through a belt conveyor, and the discharge from the buffer bin is sent to a high-level silo through a bucket elevator. The discharge from the high-level silo enters a quantitative feeder, and the quantitative feeder quantitatively feeds the materials into a molding machine for molding. The molded briquette is sent to the belt conveyor of the coal tower through a belt conveyor, and is sent to the coal tower together with the coking coal to enter the coke oven for coking. Although the invention provides a relatively low-cost method for treating waste emulsion sludge, the treatment process is relatively complicated, and the use of coking coal as fuel not only increases the treatment cost, but the performance of the final product coal shape is not improved compared with the original coking raw materials, and the calorific value of the waste emulsion sludge is not fully utilized. Summary of the invention

[0005] 1. Technical problem to be solved by the invention

[0006] Aiming at the problems in the prior art that waste emulsion sludge is difficult to treat, the treatment process is complicated, the cost is high, and secondary pollution is easily generated during the treatment process, the present invention provides a waste emulsion sludge treatment equipment. The equipment mixes the waste emulsion sludge and additives transported by the raw material feeding system and the additive feeding system into powdered combustible particles through a mixing system. The treatment process is simple and the cost is low. The product after treatment maintains the calorific value of the waste emulsion sludge and is a good fuel.

[0007] 2. Technical solution

[0008] In order to achieve the above object, the technical solution provided by the present invention is:

[0009] A waste emulsion sludge treatment device comprises: a support frame, the support frame is used to support and fix various systems of the device; a raw material feeding system, the raw material feeding system is used to quantitatively transport the waste emulsion sludge to the mixing system; an additive feeding system, the additive feeding system is used to quantitatively transport the additive to the mixing system; the mixing system, the mixing system is located below the raw material feeding system and the additive feeding system, and the waste emulsion sludge input by the raw material feeding system and the additive input by the additive feeding system are mixed and pulverized into combustible powder particles; and a discharging system is fixedly installed at the bottom of the mixing system to output the final product of the mixing system. There are two groups of support frames. One group is a "mouth-shaped" support frame for supporting and fixing the additive feeding system. There is a circular top beam on the top of the "mouth-shaped" support frame, and the main part of the additive feeding system is fixed in the top beam; the other group is a "eye-shaped" support frame for fixing the raw material feeding system and the mixing system, which is located on one side of the "mouth-shaped" support frame. One side of the "eye-shaped" support frame is used to install the vertical lifting device of the raw material feeding system, and the top beam is used to install the horizontal moving device of the raw material feeding system. The horizontal guide rail is installed on the second crossbeam from top to bottom, and the third crossbeam from top to bottom is used for fixed installation of the mixing system. Below the third crossbeam, at the outer bottom of the mixing system, the discharging system is installed. The discharging system consists of a discharging valve and a discharging pipe. The discharging system is connected to the bottom of the mixing system, and the discharge of the product material is controlled by the discharging valve. The discharging valve is closed when mixing starts, and opened when mixing is completed to start discharging.

[0010] Furthermore, the mixing system comprises: a mixing chamber cylinder, which is a cylindrical cavity and is fixedly mounted on a support frame below the raw material feeding system; a mixing chamber upper cover, which is cooperatively mounted on the upper end of the mixing chamber cylinder to seal the mixing chamber cylinder; a raw material inlet, which is opened at the edge of the mixing chamber upper cover to receive the waste emulsion sludge transported by the raw material feeding system into the mixing chamber cylinder; and an exhaust gas outlet, which is opened on the mixing chamber upper cover to discharge the waste emulsion sludge in the mixing chamber cylinder. residual waste gas; an ash inlet, which is opened on the side wall of the mixing chamber cylinder, and receives the additives transported by the additive feeding system into the mixing chamber cylinder; a main shaft, the lower end of which is rotatably fixed to the bottom of the mixing chamber cylinder; a braking device, which is fixedly connected to the lower bottom surface of the mixing chamber cylinder to provide power for the rotation of the main shaft; a mixing device, which is transmission-connected to the upper end of the main shaft, and as the main shaft rotates, the waste emulsion sludge and additives in the mixing chamber cylinder are mixed to form powdery particles.

[0011] Furthermore, the mixing system also includes a deodorizing device, which includes: a tee, the intersection of which is fixedly connected to the upper end of the main shaft in an inverted T shape; an addition port, which is connected to the pipe opening in the vertical direction of the tee and extends to the outside of the mixing chamber cylinder; a deodorant nozzle, which is connected to the pipe opening in the horizontal direction of the tee. The emulsion deodorant is added through the addition port of the tee, flows out from the pipeline connected to the deodorant nozzle after being diverted by the tee pipeline, and because the tee is fixedly connected to the upper end of the main shaft, the deodorizing device rotates when the main shaft rotates, and the added emulsion deodorant can be evenly sprinkled on the material in the mixing chamber cylinder to enhance the deodorizing effect.

[0012] Furthermore, the mixing device includes: a planetary gear box, which is connected to the upper end of the main shaft through the sun gear therein; a planetary shovel mechanism, which is connected to the planetary gear of the planetary gear box through the upper end of the rotating shaft, the transverse shaft is fixedly connected to the lower end of the rotating shaft, the planetary shovel is fixedly connected to the lower side of the transverse shaft, and the shovel tip of the planetary shovel contacts the bottom of the mixing chamber cylinder; a grinding wheel mechanism, which is fixedly connected to the outer side of the gear ring of the planetary gear box through a connecting rod, the grinding wheel is rotatably connected to one end of the connecting rod, and the grinding wheel curved surface contacts the bottom of the mixing chamber cylinder. The sun gear is a driving wheel, which is connected to the main shaft through a driving method, the planetary gear meshes with the sun gear, and the planetary shovel mechanism is connected to the planetary gear through a driving method. When the main shaft rotates, the planetary gear drives the planetary shovel mechanism to rotate, and the planetary shovel on it rotates around the main shaft while rotating itself. The grinding wheel rotates around the main shaft driven by the gear ring to grind the material stirred by the planetary shovel and crush the large pieces of material in the material.

[0013] Furthermore, the mixing device also includes a side scraper mechanism, which is fixedly connected to the outer side of the ring gear of the planetary gear box through a fixed rod; the side scraper is fixedly connected to the end of the fixed rod and contacts the side bottom end of the mixing chamber cylinder. As the main shaft rotates, the ring gear drives the side scraper mechanism to rotate, and the side scraper is in contact with the cylinder wall. When rotating, the waste emulsion sludge retained and adhered to the cylinder wall is continuously scraped off to prevent the waste emulsion sludge from being retained and accumulated on the cylinder wall. At the same time, the bottom of the side scraper also stirs the material at the bottom edge of the mixing chamber cylinder. Since the side scraper is set in contact with the bottom end of the cylinder wall, after stirring, the material at the bottom edge of the mixing chamber cylinder will be pushed to the middle part for the rolling disc to be rolled.

[0014] Furthermore, the raw material feeding system includes: a metering barrel, which is quantitatively loaded with waste emulsion sludge; a pulley, which carries and transports the metering barrel; a lifting platform, which is slidably connected to a side of the support frame to drive the pulley to rise and fall; a translation claw, which is slidably connected to a top crossbeam of the support frame and translates under the drive of the circuit, and drives the pulley to translate on the translation slide rail through the interference between the claw and the metering barrel during translation; a translation slide rail, which is fixedly connected to the bottom of the top crossbeam of the support frame and cooperates with the pulley to limit the moving trajectory of the pulley; a tilting device, which is arranged at the translation slide rail just above the raw material inlet, and flips and dumps the metering barrel after clamping it. The lifting platform and the translation claws are both controlled by the motor. The lifting platform's limit position is the translation rail. The pulley can smoothly enter the translation rail at this position. The right claw of the translation claw is used to push the quantitative barrel to the tipping device when interfering with the quantitative barrel. The left claw is used to push the quantitative barrel back to the lifting platform after the quantitative barrel has dumped the waste emulsion sludge. The distance between the left and right claws should be larger than the barrel diameter of the quantitative barrel, so that it will not interfere with the movement trajectory of the quantitative barrel during tipping. The tipping device is located at the end of the translation rail, above the mixing system. When the pulley and the quantitative barrel transported by the translation claw move to the tipping device, a clamping arm is provided on the tipping device. After clamping the quantitative barrel, the clamping arm rotates to dump the waste emulsion sludge.

[0015] Furthermore, it also includes an intermediate silo, which is funnel-shaped, with a bottom opening connected to the raw material inlet, and a top opening located below the tipping device, and a heating device is wrapped around the lower half of the intermediate silo. The funnel-shaped intermediate silo can guide the waste emulsion sludge transported by the raw material feeding system to the raw material inlet when the raw material is unloaded. The heating device of this solution is a heating wire, which heats the intermediate silo to reduce the amount of waste emulsion sludge adhering to and remaining in the intermediate silo.

[0016] Furthermore, the additive feeding system includes: an ash storage bin, which is fixed on the upper side of the mixing system through a support frame and is used to store additives; a screw feeder, the feeding end of which is connected to the ash outlet at the bottom of the ash storage bin; and an ash outlet pipe, one end of which is connected to the discharge end of the screw feeder and the other end is connected to the ash inlet. The transport tank truck transports the fly ash additive to the ash storage bin, and the fly ash is transported by the screw feeder. The screw feeder can set the parameters for transporting the fly ash additive according to the parameters of the weighing feeder, thereby accurately controlling the quality of the fly ash transported to the mixing system.

[0017] Furthermore, the equipment of the present application adopts the following process to treat waste emulsion sludge:

[0018] 1. Quantitative collection: Use a quantitative bucket to collect a certain amount of waste emulsion sludge and place it on a pulley;

[0019] 2. Raw material loading: Start the lifting platform, lift the pulley to the height of the translation slide rail, start the translation claw, translate the pulley to the tipping device, start the tipping device, clamp and flip the quantitative barrel, pour the waste emulsion sludge into the intermediate silo, and enter the mixing chamber cylinder through the intermediate silo;

[0020] 3. Additive feeding: Start the screw feeder, and according to the feeding amount of waste emulsion sludge, convey a certain amount of additives into the ash discharge pipe in proportion, and convey them to the mixing chamber cylinder through the ash inlet;

[0021] 4. Mixing: Start the brake device to drive the mixing device to operate. The roller squeezes the waste emulsion sludge while rotating to squeeze out the water and oil in the waste emulsion sludge. The planetary shovel revolves around the main axis while rotating to fully mix the additive with the squeezed waste emulsion sludge. Continue this step for a certain period of time until the mixture of the waste emulsion sludge and the additive becomes a powdery granular material.

[0022] 5. Discharging: The mixed powdery granular materials are discharged through the discharging system and packed in barrels or bags.

[0023] The water content of the raw material, i.e., waste emulsion sludge, is ≤50%; the additive is fly ash, the water content of the added fly ash is ≤1%, wherein the content of particles with a particle size of ≤1 mm is ≥90%; the ratio of the mass of the waste emulsion sludge added to the mixing system to the mass of the fly ash transported to the mixing system is 1:(1-5); and the mixing process lasts for 10-30 minutes.

[0024] 3. Beneficial effects

[0025] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0026] (1) The waste emulsion sludge treatment equipment of the present invention adds waste emulsion sludge and fly ash into a mixing system in a certain mass ratio through a raw material feeding system and an additive feeding system. After a certain period of mixing, rolling and stirring in the mixing system, the waste emulsion sludge and fly ash form combustible powder particles that are output by a discharging system. The final treated product has a low water content and a certain calorific value, and can be fully burned as a fuel. During combustion, the combustion equipment and the feeding system will not be blocked, and the waste emulsion sludge, an industrial hazardous waste, is successfully turned into treasure. When the equipment treats the waste emulsion sludge, no new chemical reaction is involved, so no new industrial hazardous substances are generated. The process flow is simple, the treatment cost is low, and it is suitable for industrial application.

[0027] (2) The waste emulsion sludge treatment equipment of the present invention is provided with a closed mixing system. When the waste emulsion sludge and fly ash are mixed, no odor and dust will be emitted, thereby ensuring the working environment of the workshop; the exhaust gas outlet is connected to the exhaust gas treatment equipment, and the dust and gas emitted during the mixing process are treated and discharged after meeting the standards; since the equipment does not produce a chemical reaction when treating the waste emulsion sludge, the mixing system is closed for mixing, which ensures the workshop environment and does not pose a safety hazard; the process of treating the waste emulsion sludge by the equipment has little erosion effect on the mixing system and other systems, and the maintenance cost of the equipment is greatly reduced;

[0028] (3) The waste emulsion sludge treatment equipment of the present invention is provided with a deodorizing device, which can add an emulsion deodorizer into the mixing system. As the main shaft rotates, the emulsion deodorizer is evenly sprinkled on the material in the mixing chamber cylinder, thereby achieving the purpose of enhancing the deodorizing effect. The waste emulsion sludge that has been stored for too long is difficult to mix and treat. When mixing, adding an emulsion deodorizer with a mass of 3‰ of the mass of the waste emulsion sludge can reduce the difficulty of mixing and treatment, and obtain a qualified treatment product.

[0029] (4) A waste emulsion sludge treatment device of the present invention, after the waste emulsion sludge and fly ash are fed into a mixing system according to a certain ratio, the grinding wheel of the mixing device separates the water and oil in the waste emulsion sludge, and the planetary shovel mechanism fully stirs and mixes the waste emulsion sludge and fly ash, so that the water and oil are fully absorbed by the fly ash, and the large pieces of material continue to be crushed by the grinding wheel. After repeated treatment for a period of time, a stable powdered granular product with a water content of ≤10% can be obtained. The product obtained by the mixing device has a certain calorific value, is combustible, and burns fully with a high combustion rate. It can be used as a fuel and can improve the efficiency of heating equipment such as furnaces;

[0030] (5) The waste emulsion sludge treatment equipment of the present invention is provided with a side scraper mechanism, which can timely scrape off the waste emulsion sludge retained and adhered to the cylinder wall during the mixing process to prevent its continuous accumulation from affecting the operation of the mixing device and the product quality; the side scraper mechanism can also stir the material at the bottom edge of the cylinder and push it to the center of the cylinder, ensuring that the materials in the mixing chamber are evenly mixed, and there is no dead angle in the mixing process, thereby ensuring the quality of the mixed product;

[0031] (6) In the waste emulsion sludge treatment equipment of the present invention, the raw material feeding system can quantitatively and stably transport the waste emulsion sludge to the top of the mixing system for feeding. The raw material feeding process is automatically controlled by a motor, which saves time and effort. The amount of raw material fed each time is a fixed value, which is convenient for quality control when the additive is fed. The lifting and translation process of the feeding is stable, and the waste emulsion sludge will not spill out to pollute the equipment and workshop environment. The present application improves the tipping device in the raw material feeding system so that the raw material can be tipped 180° when dumping, which greatly reduces the feeding quality error caused by the waste emulsion sludge being easily adhered to the barrel wall due to its high viscosity, and facilitates the subsequent calculation operations such as additive batching and final output control.

[0032] (7) A waste emulsion sludge treatment device of the present invention is provided with an intermediate silo to prevent the quantitative barrel of the raw material feeding system from overflowing and spilling outside the mixing system when dumping the waste emulsion sludge. The lower part of the intermediate silo is provided with a heating device, which can heat the waste emulsion sludge in the intermediate silo to ensure its fluidity and reduce its retention and adhesion in the intermediate silo; a weighing feeder is provided at the bottom of the intermediate silo connected to the raw material inlet, which can weigh and control the quality of the waste emulsion sludge entering the mixing system each time, which is convenient for calculating other process parameters of the equipment and also convenient for controlling the final output; the weighing feeder and the heating device can cooperate to heat the waste emulsion sludge before entering the mixing system to a specified temperature, so that the final powder particle product is not easy to clump and agglomerate, thereby improving the use quality of the product;

[0033] (8) A waste emulsion sludge treatment device of the present invention, the screw feeder in the additive feeding system can accurately control the mass of the fly ash additive to be transported according to the mass of the waste emulsion sludge finally fed into the mixing system by the raw material feeding system, ensure that the material ratio input into the mixing system is within a given range, and ensure the quality of the final mixed product;

[0034] (9) The waste emulsion sludge treatment equipment of the present invention adopts a corresponding process to treat the waste emulsion sludge. The treatment process is short in time. It only takes 10 to 30 minutes to mix the waste emulsion sludge with fly ash into combustible particles that can be fully burned as fuel. The calorific value of the mixed product is between 5 and 15 MJ / kg. The process flow is simple. After the process parameters are calculated and set for the initial treatment of the same type of waste emulsion sludge, there is no need to repeatedly calculate the process parameters for subsequent treatment. It is convenient and has a high processing speed, which is suitable for industrial production needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0048] Example 1

[0049] A waste emulsion sludge treatment device of this embodiment, such as Figure 1 As shown, including:

[0050] A support frame 5, the support frame 5 is used to support and fix various systems of the device;

[0051] A raw material feeding system 1, wherein the raw material feeding system 1 is used to quantitatively transport the waste emulsion sludge to the mixing system 3;

[0052] An additive feeding system 2, the additive feeding system 2 is used to quantitatively transport additives to the mixing system 3;

[0053] A mixing system 3, the mixing system 3 is located below the raw material feeding system 1 and the additive feeding system 2, and mixes the waste emulsion sludge input from the raw material feeding system 1 with the additive input from the additive feeding system 2 to form a combustible powdery particle;

[0054] The discharging system 4 is fixedly installed at the bottom of the mixing system 3 to output the final product of the mixing system 3 .

[0055] In the existing waste emulsion treatment, chemical treatment is mostly used. After demulsification, flocculation, flotation, water treatment and other processes, the waste emulsion is finally treated and discharged. This treatment method first requires special equipment, and a series of chemical reactions are carried out in the equipment. It is difficult for the treated products and accompanying materials to meet the emission standards, and the emission increases the environmental burden. Moreover, according to detection and analysis, the calorific value of industrial waste emulsion sludge is about 20MJ / kg. It is also a waste of resources to only discharge it after treatment. The present application designs a treatment device for waste emulsion sludge, which aims to mix waste emulsion sludge and additives in a specific proportion range through two feeding systems, make the waste emulsion sludge into a combustible powdered fuel, and make full use of the potential calorific value of the waste emulsion sludge. In addition, the mixing process of the present application does not involve chemical reactions, and no additional pollutants are generated. Through mixing treatment, the problem of solid residue and viscosity in the waste emulsion sludge affecting combustion is solved, and the calorific value of the final product is 5-15MJ / kg.

[0056] The waste emulsion sludge treatment equipment of this embodiment has two groups of support frames 5. One group is a "mouth-shaped" support frame 5 for supporting and fixing the additive feeding system 2. The top of the "mouth-shaped" support frame 5 has an annular top beam, and the main part of the additive feeding system 2 is fixed in the top beam; the other group is a "mesh-shaped" support frame 5 for fixing the raw material feeding system 1 and the mixing system 3, which is located on one side of the "mouth-shaped" support frame 5. One side of the "mesh-shaped" support frame 5 is used to install the vertical lifting and lowering of the raw material feeding system 1. The top beam is used to install the horizontal moving device of the raw material feeding system 1, the horizontal guide track is installed on the second crossbeam from top to bottom, and the third crossbeam from top to bottom is used to fix the mixing system 3. Below the third crossbeam, the outer bottom of the mixing system 3, is installed with a discharge system 4. The discharge system 4 of this embodiment is composed of a discharge valve and a discharge pipe. The discharge system 4 is connected to the bottom of the mixing system 3, and the discharge of the product material is controlled by the discharge valve. The discharge valve is closed when mixing starts, and opened when mixing is completed to start discharging.

[0057] The raw material feeding system 1 of this embodiment is used to transport a certain amount of waste emulsion sludge to the mixing system 3. The additive feeding system 2 transports a corresponding proportion of additives to the mixing system 3 according to the mass of the waste emulsion sludge transported by the raw material feeding system 1 to the mixing system 3. The additive is fly ash, and the mass ratio of the waste emulsion sludge to the fly ash is 1:(1-5). The higher the water content of the waste emulsion sludge, the greater the mass of the corresponding added fly ash. When the water content of the waste emulsion sludge transported by the raw material feeding system 1 is ≤ % water content, the mass of the fly ash transported by the additive feeding system 2 is the same as the mass of the waste emulsion sludge added. When the water content of the waste emulsion sludge transported by the raw material feeding system 1 is between 45% and 50%, the additive feeding system The mass of fly ash transported by system 2 is 5 times the mass of waste emulsion sludge added. When the water content of waste emulsion sludge transported into mixing system 3 is between 10% and 45%, the added mass ratio of fly ash increases with the increase of water content; after waste emulsion sludge and fly ash are transported to mixing system 3 according to the corresponding mass ratio, mixing system 3 is started to mix the feed. The feed is mixed, rolled and stirred in mixing device 3. The mixing process lasts for 10 to 30 minutes. Waste emulsion sludge and fly ash are fully mixed and pulverized to finally form combustible powder particles, which are discharged by discharging system 4. The water content of the final product is less than 10%, it is not sticky when grasped by hand, and it has a certain calorific value and can be fully burned as fuel.

[0058] Example 2

[0059] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of embodiment 1, such as Figure 5 As shown, the mixing system 3 comprises:

[0060] The mixing chamber barrel 33 is a cylindrical cavity, which is fixedly mounted on the support frame 5 below the raw material feeding system 1;

[0061] The mixing chamber upper cover 30 is mounted on the upper end of the mixing chamber cylinder 33 to seal the mixing chamber cylinder 33;

[0062] A raw material inlet 31 is provided at the edge of the upper cover 30 of the mixing chamber, and receives the waste emulsion sludge transported by the raw material feeding system 1 into the mixing chamber barrel 33;

[0063] An exhaust gas outlet 32 ​​is provided on the mixing chamber upper cover 30 to discharge the excess exhaust gas in the mixing chamber barrel 33;

[0064] The ash inlet 34 is provided on the side wall of the mixing chamber cylinder 33 to receive the additive transported by the additive feeding system 2 and enter the mixing chamber cylinder 33;

[0065] A main shaft 353, the lower end of which is rotatably fixed to the bottom of the mixing chamber cylinder 33;

[0066] A brake device 35, which is fixedly connected to the outer lower surface of the mixing chamber cylinder 33 and provides power for the rotation of the main shaft 353;

[0067] The mixing device 37 is connected to the upper end of the main shaft 353 by driving means. As the main shaft 353 rotates, the waste emulsion sludge and additives in the mixing chamber barrel 33 are mixed to form powdery particles.

[0068] Waste emulsion sludge is very smelly and toxic, and fly ash is easy to generate dust. Therefore, when the two are mixed, they cannot be operated in an open environment. This embodiment is provided with a mixing chamber cylinder 33 of a cylindrical cavity type, and a mixing chamber upper cover 30 is added to allow the two to be mixed in a closed environment. Since the waste emulsion sludge has a large viscosity and the fly ash is fine dust, the fluidity of the two in a closed environment is very poor. Therefore, the raw material inlet 31 is set at the edge of the mixing chamber upper cover 30 near the ash inlet 34. When the waste emulsion sludge and fly ash are added to the mixing chamber cylinder 33, the mixing chamber cylinder 33 is opened. The fly ash will roughly wrap the waste emulsion sludge, making it convenient for the mixing device 37 to mix the two; the main shaft 353 is arranged in the middle of the mixing chamber cylinder 33, and is driven to rotate by the brake device 35 arranged on the outer bottom surface of the mixing chamber cylinder 33. The brake device 35 is composed of a motor, a transmission belt and a reduction gearbox. The reduction gearbox is connected to the motor through the transmission belt, and the main shaft 353 is connected to the reduction gearbox; the mixing device 37 is a device for mixing the waste emulsion sludge and the fly ash, and operates under the drive of the main shaft 353.

[0069] When the waste emulsion sludge and the additive fly ash are added to the mixing system 3, after the mixing starts, the structure of the mixing system 3 is closed, the raw material inlet 31 and the ash inlet 34 are not connected to the workshop environment, and the discharge valve of the discharge system 4 is also closed during mixing. Only the waste gas outlet 32 ​​is connected to the waste gas treatment equipment, and the particulate dust and odor emitted by the mixing are removed and discharged after dust and odor removal. Therefore, the working environment of the workshop where the equipment is located is guaranteed during the mixing process. In addition, since the mixing process is a series of physical changes such as mixing, rolling and stirring, and does not involve chemical reactions, there is no need to A large amount of heat or gas will be generated, and the closed mixing system 3 will not have any safety risks. When the equipment of the present application treats waste emulsion sludge, the cost consumed is only the electricity to maintain the operation of the equipment and the added fly ash. Fly ash is the industrial waste residue discharged by coal-fired power plants and is also a resource that needs to be processed and utilized. Therefore, the equipment operation cost is very low. Compared with other waste emulsion sludge treatment equipment, this equipment does not involve chemical reactions, so it is more environmentally friendly and economical, and the equipment will not be corroded by various compound preparations, has a longer service life, and greatly reduces the equipment maintenance cost.

[0071] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of embodiment 2, such as Figure 5 and Figure 6 As shown, the mixing system 3 further includes a deodorizing device 36, and the deodorizing device 36 includes:

[0072] A tee pipe 360, wherein the intersection of the tee pipe 360 ​​is inverted T-shaped and fixedly connected to the upper end of the main shaft 353;

[0073] The adding port 361 is connected to the vertical pipe opening of the three-way pipe 360, and the adding port 361 extends to the outside of the mixing chamber barrel 33;

[0074] The deodorant nozzle 362 is connected to the horizontal pipe opening of the three-way pipe 360.

[0075] In order to reduce the processing pressure of the waste gas treatment equipment connected to the waste gas outlet 32 ​​and ensure that the discharged waste gas meets the emission standards, an emulsion deodorant can be added during mixing. The emulsion deodorant is added through the addition port 361 of the tee pipe 360, and flows out from the pipeline connected to the deodorant nozzle 362 after the diversion of the tee pipe 360 ​​pipeline. Since the tee pipe 360 ​​is fixedly connected to the upper end of the main shaft 353, the deodorizing device 36 also rotates when the main shaft 353 rotates. The added emulsion deodorant can be evenly sprinkled on the material in the mixing chamber barrel 33 to enhance the deodorizing effect.

[0076] In actual production, it is found that after the waste emulsion sludge is stored for 48 hours, its odor gradually becomes heavier and its viscosity increases. During the mixing process, the mixing and powdering effect is not ideal. The final product is a sticky block. When it is burned, there is a lot of residue and it cannot be fully burned. The addition of emulsion deodorant can solve this problem. Although there are many brands of existing emulsion deodorants, the deodorization mechanism is basically the same. They all deodorize by chemically reacting with the waste emulsion sludge. When treating the waste emulsion sludge stored for more than 48 hours, the emulsion deodorant is added to the mixing system 3 through the deodorizing device 36. The added mass of the emulsion deodorant is 3‰ of the added mass of the waste emulsion sludge. As the main shaft 353 rotates, the added emulsion deodorant evenly reacts with the material in the mixing chamber barrel 33. While deodorizing, it reduces the difficulty of mixing during the mixing process. The final product is powdery, non-sticky, and fully burned.

[0077] Example 4

[0078] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of embodiment 2 or 3, such as Figure 7 , Figure 8 and Fig. 9 As shown, the mixing device 37 comprises:

[0079] A planetary gear box 370, wherein the planetary gear box 370 is connected to the upper end of the main shaft 353 by a sun gear therein;

[0080] A planetary shovel mechanism 372, wherein the planetary shovel mechanism 372 is drivingly connected to the planetary wheel through the upper end of the rotating shaft 3720, the horizontal shaft 3721 is fixedly connected to the lower end of the rotating shaft 3720, the planetary shovel 3722 is fixedly connected to the lower side of the horizontal shaft 3721, and the shovel tip of the planetary shovel 3722 contacts the bottom of the mixing chamber cylinder 33;

[0081] The grinding wheel mechanism 373 is fixedly connected to the outer side of the gear ring of the planetary gear box 370 through a connecting rod 3730, and the grinding wheel 3731 is rotatably connected to one end of the connecting rod 3730, and the curved surface of the grinding wheel 3731 contacts the bottom of the mixing chamber barrel 33.

[0082] The planetary gear box 370 is an existing mechanical structure, and the ring gear thereof is a planetary gear system, wherein a plurality of planetary gears rotate around a sun gear, and the planetary gears also rotate on their own. The sun gear is a driving gear, which is connected to the main shaft 353 by transmission, and the planetary gears mesh with the sun gear. The planetary shovel mechanism 372 is connected to the planetary gear by transmission. When the main shaft 353 rotates, the planetary gear drives the planetary shovel mechanism 372 to rotate, and the planetary shovel 3722 thereon rotates around the main shaft while rotating itself. The planetary shovel mechanism 372 of this embodiment is provided with three planetary shovels 3722. Compared with the traditional rotary stirring, the planetary shovel 372 2 has a more varied rotation trajectory, and the material in the mixing chamber barrel 33 can be stirred more comprehensively and thoroughly, and the mixing effect of the material is better. The grinding wheel 373 rotates around the main shaft 353 driven by the ring gear, and grinds the material after being stirred by the planetary shovel 3722, and crushes the large pieces of material in the material. In this embodiment, two grinding wheel mechanisms 373 and two planetary shovel mechanisms 372 are provided, and the grinding wheel mechanism 373 and the planetary shovel mechanism 372 are arranged adjacent to each other. The material crushed by the grinding wheel 3731 is further stirred and mixed by the planetary shovel mechanism 372 thereafter, and then squeezed and crushed by the grinding wheel 3731.

[0083] When the waste emulsion sludge is kneaded by the mixing device 37, the water and oil therein are crushed and precipitated by the grinding wheel 3731. Subsequently, under the sufficient stirring of the planetary shovel 3722, the precipitated water and oil are fully wrapped and absorbed by the fly ash. The large particles formed after the fly ash absorbs the water or oil and the original block residue in the waste emulsion sludge are crushed again under the continued rolling of the grinding wheel 3731. The mixing is repeated in this way. When the added mass ratio of the waste emulsion sludge to the fly ash is within the specified range and the mixing time is up to the standard, the mixing device 37 of this embodiment can process the waste emulsion sludge into stable powder particles with a water content of ≤10% and no stickiness. This product has a certain calorific value, is combustible, and burns fully. Using it as a fuel can greatly improve the efficiency of heating equipment such as furnaces.

[0084] Example 5

[0085] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of embodiment 4, such as Figure 7 and Fig.10 As shown, the mixing device 37 also includes a side scraper mechanism 371, which is fixedly connected to the outer side of the ring gear of the planetary gear box 370 through a fixing rod 3710; the side scraper 3711 is fixedly connected to the end of the fixing rod 3710 and contacts the bottom end of the side of the mixing chamber barrel 33.

[0086] The material added to the mixing chamber barrel 33 will be squeezed by the roller 3731, and part of it will be squeezed toward the barrel wall. Since the waste emulsion sludge has a certain viscosity, the roller 3731 and the planetary shovel 3722 at the barrel wall cannot contact it. The waste emulsion sludge squeezed toward the barrel wall may be retained and adhered to the barrel wall. If the untreated waste emulsion sludge is left for too long, its viscosity will increase greatly. The waste emulsion sludge adhered to the barrel wall will accumulate continuously, which will not only affect the operation of the mixing device 37, but also the waste emulsion sludge condensed into hard lumps on the barrel wall will not be easy to break after falling off, which will affect the combustion effect of the product. Therefore, the present embodiment is provided with a side scraper mechanism 371, which moves along with the main shaft 353 The gear ring drives the side scraper mechanism 371 to rotate, and the side scraper 3711 is in contact with the cylinder wall. When rotating, the waste emulsion sludge retained and adhered to the cylinder wall is continuously scraped off to prevent the waste emulsion sludge from being retained and accumulated on the cylinder wall. At the same time, the bottom of the side scraper 3711 also stirs the material at the bottom edge of the mixing chamber cylinder 33. Since the side scraper 3711 is arranged in contact with the bottom end of the cylinder wall, after stirring, the material at the bottom edge of the mixing chamber cylinder 33 will be pushed to the middle part for rolling by the rolling disc 3731, which further ensures the mixing effect of the materials in the mixing system 3, ensures the qualified rate and high quality rate of the mixed products, and greatly reduces the output rate of low-quality products with poor combustion effect.

[0087] Furthermore, the present embodiment has two side scraper mechanisms 371, two grinding wheel mechanisms 373, and two planetary shovel mechanisms 372, which are arranged on the planetary wheel box 370. Mechanisms of the same type are not arranged adjacent to each other. When the main shaft 353 rotates, each mechanism can evenly act on the material in the mixing chamber barrel 33, further ensuring the uniformity of the quality of the mixed product.

[0088] Example 6

[0089] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of any one of embodiments 1 to 5, such as Figure 3 and Figure 4 As shown, the raw material feeding system 1 comprises:

[0090] A quantitative barrel 10, wherein the quantitative barrel 10 is quantitatively loaded with waste emulsion sludge;

[0091] A trolley 12, wherein the trolley 12 carries and transports the quantitative barrel 10;

[0092] A lifting platform 11, wherein the lifting platform 11 is slidably connected to a side of the support frame 5, and drives the pulley 12 to rise and fall;

[0093] A translation claw 13, wherein the translation claw 13 is slidably connected to a top crossbeam of the support frame 5, and is translated under the drive of the circuit, and the pulley 12 is driven to translate on the translation rail 14 by the interference between the claw and the quantitative barrel 10 during translation;

[0094] A translation rail 14, which is fixedly connected to the bottom of the top crossbeam of the support frame 5 and cooperates with the pulley 12 to limit the movement track of the pulley 12;

[0095] The tilting device 15 is arranged at the translation slide rail 14 just above the raw material inlet 31, and is used to clamp the metering barrel 10 and then flip and tilt it.

[0096] The metering barrel 10 has a fixed capacity and can be loaded with the same mass of waste emulsion sludge each time for loading. The metering barrel 10 loaded with waste emulsion sludge is placed on the pulley 12, and the pulley 12 is placed on the lifting platform 11. When loading, the motor is started, and the lifting platform 11 drives the pulley 12 and the metering barrel 10 to the position of the translation slide rail 14. At this time, the movement trajectory of the claw of the translation claw 13 interferes with the metering barrel 10, so that when the translation claw 13 is translated, the claw can drive the metering barrel 10 to move, and when the metering barrel 10 moves, it drives the pulley 12. A pulley is installed at the bottom of the pulley 12, which can just enter the translation slide rail 14. Finally, the translation claw 13 smoothly brings the metering barrel 12 to the position of the tilting device 15 for tilting operation.

[0097] The lifting platform 11 and the translation claw 13 of this embodiment are both controlled by a motor. The upper limit position of the lifting platform 11 is the translation rail 14. The pulley 12 can smoothly enter the translation rail 14 at this position. The right claw of the translation claw 14 is used to push the quantitative barrel 10 to the tipping device 15 when interfering with the quantitative barrel 10. The left claw is used to push the quantitative barrel 10 back to the lifting platform 11 after the quantitative barrel 10 has dumped the waste emulsion sludge. The distance between the left and right claws is larger than the barrel diameter of the quantitative barrel 10, so that it will not interfere with the movement trajectory of the quantitative barrel 10 during tipping.

[0098] The tipping device 15 is arranged at the end of the translation slide rail 14, and is located above the mixing system 3. When the pulley 12 and the metering barrel 10 transported by the translation claw 13 move to the tipping device 15, a clamping arm is provided on the tipping device 15. After clamping the metering barrel 10, the clamping arm rotates to dump the waste emulsion sludge.

[0099] It is found in production operation that, due to the certain viscosity of the waste emulsion sludge, the waste emulsion sludge cannot be completely poured out when the tipping angle is small, and a large amount of it remains on the wall of the quantitative barrel 10. The excessive amount of residue is not convenient for calculating the mass of the additive. In view of this, the tipping device 15 is further improved in this embodiment:

[0100] When the pulley 12 runs to the position of the tipping device 15, the track of the part where it is located can be flipped, and the tipping track is connected to the translation slide rail 14. A stepper motor is fixedly connected to the crossbeam of the support frame 5 where the translation slide rail 14 is connected to the tipping track. The output shaft of the stepper motor is transmission-connected to the tipping track. When the pulley 12 runs to the tipping track, the clamping arm clamps the metering barrel 10. At this time, the metering barrel 10, the pulley 12 and the tipping track are all fixed by the clamping arm. The stepper motor is started to rotate the tipping track, so that the metering barrel 10 is tilted 180° and then dumped. The waste emulsion sludge can be more thoroughly delivered to the mixing system 3, and only a small amount remains on the barrel wall of the metering barrel 10. The residual amount will not affect the quality of the calculated additive feeding.

[0101] Example 7

[0102] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of embodiment 6, such as Fig.11 As shown, it also includes an intermediate silo 6 , which is funnel-shaped, with a bottom opening connected to the raw material inlet 31 and a top opening located below the tilting device 15 .

[0103] The funnel-shaped intermediate silo 6 can prevent the raw materials in the metering barrel 10 from overflowing and spilling outside the mixing system 3 when the raw materials are discharged, and guide the waste emulsion sludge transported by the raw material feeding system 1 to the raw material inlet 31.

[0104] Example 8

[0105] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of embodiment 7, such as Fig.11 As shown, the lower half of the intermediate silo 6 is enclosed by a heating device 61 .

[0106] The heating device 61 can be a heating component such as a heating wire. In this embodiment, a heating wire is used, and the heating wire is wrapped around the lower half of the intermediate silo 6. After the raw material feeding system 1 pours the waste emulsion sludge into the intermediate silo 6, the waste emulsion sludge with high viscosity is easy to adhere to and remain on the side wall of the intermediate silo 6, especially since the diameter of the lower half of the intermediate silo 6 is small, and the fluidity of the waste emulsion sludge is very poor. The heating wire heats the intermediate silo 6, and the waste emulsion sludge can restore its fluidity after being heated, thereby ensuring smooth unloading.

[0107] Because the waste emulsion sludge has a part of mass loss in the quantitative barrel 10 and the intermediate silo 6 before entering the mixing system 3, in order to ensure the accuracy of the calculation of the mass of the additive added when the additive is loaded, a weighing feeder is provided at the bottom of the intermediate silo 6 connected to the raw material inlet 31. The weighing feeder is an existing mechanism that can weigh the amount of material discharged and accurately control the amount of material discharged. By setting up the weighing feeder, the influence of the mass loss of the waste emulsion sludge during transportation on the result of calculating the amount of additive added can be eliminated, thereby ensuring the quality of the mixed product.

[0108] The temperature of the waste emulsion sludge is controlled by the heating device 61 to reach 120-230°C before being sent to the mixing system 3. Compared with the product directly sent to the mixing system 3 for mixing through the raw material feeding system 1, the product after mixing is less likely to clump and agglomerate. The product directly sent to the mixing system 3 for mixing without heating has the phenomenon of clumping and agglomeration, which affects its use as fuel. A low heating temperature is selected for waste emulsion sludge with low water content, and a high heating temperature is selected for waste emulsion sludge with high water content.

[0109] Since the mixing chamber cylinder 33 is a closed structure, when the heated waste emulsion sludge is added to the mixing system 3, the mixing process can be maintained at a relatively high temperature, accelerating the evaporation of water in the material, and further ensuring that the water content of the product reaches the combustible standard.

[0110] The weighing feeder can cooperate with the heating device 61. After the waste emulsion sludge is added to the intermediate silo 6, the weighing feeder will temporarily store it for a period of time and heat it with the heating wire. When the temperature reaches 120-230°C, weighing and feeding are carried out. Since the mass of each loading of the quantitative barrel 10 is constant, the mass of the waste emulsion sludge transported to the intermediate silo 6 is also basically the same (slightly affected by the retention of the barrel wall). Therefore, when the weighing feeder controls the feeding each time, the feeding value can be set to be close to the mass of the loading of the quantitative barrel 10 and less than the fixed value of the mass of the loading of the quantitative barrel 10. With the cooperation of the raw material feeding system 1, there will be neither an increase in the accumulation of materials in the intermediate silo 6 nor an insufficient amount of feeding. At this time, the feeding mass of the additive feeding system 2 is also easier to calculate, which simplifies the calculation difficulty of the processing parameters of the equipment and makes the output of the waste emulsion sludge treated by the equipment easier to control.

[0111] Example 9

[0112] The waste emulsion sludge treatment equipment of this embodiment is further improved on the basis of any one of embodiments 1 to 8, such as Figure 2 As shown, the additive feeding system 2 includes:

[0113] An ash storage bin 20, which is fixed above the mixing system 3 through a support frame 5 and is used to store additives;

[0114] A screw feeder 21, wherein a feeding end of the screw feeder 21 is connected to an ash outlet 201 at the bottom of the ash storage bin 20;

[0115] An ash discharging pipe 22 , one end of which is connected to the discharging end of the spiral feeder 21 , and the other end of which is connected to the ash inlet 34 .

[0116] The transport tank truck transports the fly ash additive and stores it in the ash storage bin 20. The fly ash is transported by the screw feeder 21. After being transported to the ash outlet pipe 22, the fly ash falls into the mixing system 3 from the ash material inlet 34. The screw feeder 21 is an existing powder material transportation mechanism, which can weigh, control and steadily transport the transported materials. The feeding value of the screw feeder 21 for the fly ash mass is set according to the waste emulsion sludge added mass value set by the weighing feeder in the intermediate silo 6, thereby achieving an accurate ratio of the waste emulsion sludge and fly ash in the mixing system 3, ensuring the quality of the mixed product of this equipment.

[0117] Example 10

[0118] A waste emulsion sludge treatment device of this embodiment is further improved on the basis of any one of embodiments 1 to 9, and uses the following process to treat waste emulsion sludge:

[0119] 1. Quantitative collection: Use a quantitative bucket 10 to collect a quantitative amount of waste emulsion sludge and place it on a pulley 12;

[0120] 2. Raw material loading: Start the lifting platform 11, lift the pulley 12 to the height of the translation slide rail 14, start the translation claw 13, translate the pulley 12 to the tipping device 15, start the tipping device 15, clamp and flip the metering barrel 10, pour the waste emulsion sludge into the intermediate silo 6, and enter the mixing chamber cylinder 33 through the intermediate silo 6;

[0121] 3. Additive feeding: Start the screw feeder 21, and according to the feeding amount of the waste emulsion sludge, feed a fixed amount of additives into the ash discharge pipe 22 in proportion, and then feed them into the mixing chamber cylinder 33 through the ash inlet 34;

[0122] 4. Mixing: The brake device 35 is started to drive the mixing device 37 to operate. The roller 3731 squeezes the waste emulsion sludge while rotating to squeeze out the water and oil in the waste emulsion sludge. The planetary shovel 3722 revolves around the main shaft 353 while rotating to fully mix the additive with the squeezed waste emulsion sludge. This step is continued for a certain period of time until the mixture of the waste emulsion sludge and the additive becomes a powdery granular material.

[0123] 5. Discharging: The mixed powdery granular material is discharged through the discharging system 4 and packed into barrels or bags.

[0124] The water content of the raw material, i.e. the waste emulsion sludge, is ≤50%. If the water content of the waste emulsion sludge is greater than 50%, a large amount of additives need to be added during the mixing process to absorb the water, and the final product cannot meet the fuel combustion requirements. In actual production, the waste emulsion sludge with too high a water content (greater than 50%) needs to be dehydrated before being added to the equipment.

[0125] The additive is fly ash. The water content of the fly ash added by the equipment is ≤1%, among which the content of particles with a particle size of ≤1mm is ≥90%. After many experiments, it was found that when the water content of the added fly ash is greater than 1%, the mixed product is easy to agglomerate, which is not conducive to combustion. If the particle size of the added fly ash is large, the mixing effect is very poor during the mixing process, and the particle size of the final product is large and cannot be fully burned.

[0126] The equipment first uses the quantitative barrel 10, and the mass of the waste emulsion sludge collected each time is a fixed value, which reduces the task of setting other process parameters that need to be adaptively adjusted during continuous production; the quantitative barrel 10 placed on the pulley 12 is stably transported to the tipping device 15 through the lifting platform 11 and the translation slide rail 14, and then the quantitative barrel 10 is tipped 180 degrees to ensure that the waste emulsion sludge therein is almost completely poured into the intermediate silo 6, and only a small amount adheres to the barrel wall, which has little effect on the subsequent mixing operation and can be ignored; the waste emulsion sludge added to the intermediate silo 6 is heated by the heating device 61 After heating, its fluidity is greatly increased, and it will not adhere too much to the side wall of the intermediate silo 6. According to the different water contents of the waste emulsion sludge from low to high, the heating device 61 heats it to 120-230°C, and then the heated waste emulsion sludge is quantitatively added to the mixing system 3 by the weighing feeder. The product of the pre-heated waste emulsion sludge for mixing operation is less likely to clump and agglomerate when stored; according to the mass of the raw materials transported by the weighing feeder, the mass of the fly ash transported by the screw feeder 21 is set accordingly, and the mass of the waste emulsion sludge added to the mixing system 3 is equal to the mass of the fly ash transported to the mixing system 3. The mass ratio of the waste emulsion sludge and the fly ash is 1: (1-5), and the amount of fly ash added is from low to high according to the water content of the added waste emulsion sludge. If the amount of fly ash added is too small, the mixed product will have a high water content, a large viscosity, and cannot be fully burned. If the amount of fly ash added is too large, the mixed product will have less combustible components and the product will not be easy to burn. After the waste emulsion sludge and fly ash are added to the mixing system 3 according to the ratio, the mixing device 37 mixes the materials in the mixing chamber cylinder 33, and the mixing process lasts for 10 to 30 minutes. The mixing process of the waste emulsion sludge with low water content lasts for a shorter time. The mixing process of waste emulsion sludge with high water content lasts for a long time. If the mixing process time is too short, the materials in the mixing chamber barrel 33 will not be completely mixed, affecting the combustion effect of the final product. If the mixing process time is too long, it will waste time. The final mixed product is discharged by the discharge valve at the bottom of the mixing chamber barrel 33, and is barreled or bagged and sent to the combustion equipment for combustion. The water content of the mixed product is less than 10%, and the content of particles with a particle size of ≤10mm in the mixed product is ≥88%. It is not sticky when grabbed by hand, and has a certain calorific value of 5-15MJ / kg, which can be fully burned as fuel.

[0127] When the waste emulsion sludge treatment equipment performs the first mixing treatment on the treated waste emulsion sludge and sets the corresponding parameters, in the subsequent treatment process of the same kind of treated raw materials, according to the previously set process parameters, the additives are fed first and then the raw materials are fed, so that the mixing effect is better during mixing. After the mixing is completed, less waste emulsion sludge adheres to the barrel 33 of the mixing chamber.

[0128] In a specific application, waste emulsion sludge with a water content of 25% and an oil content of 30% is treated, the water content of the added fly ash is ≤1%, the content of particles with a particle size of ≤1mm is about 96%, the ratio of the feeding mass of the waste emulsion sludge to the feeding mass of the fly ash is 1:2.5, the mixing process lasts for 25 minutes, the water content of the mixing product is less than 10%, the content of particles with a particle size of ≤10mm is 88%, it is not sticky when grasped by hand, and the calorific value is measured to be 5MJ / kg.

[0129] In a specific application, waste emulsion sludge with a water content of 18% and an oil content of 45% is treated, the water content of the added fly ash is ≤1%, the content of particles with a particle size of ≤1mm is about 96%, the ratio of the feeding mass of the waste emulsion sludge to the feeding mass of the fly ash is 1:2, the mixing process lasts for 20 minutes, the water content of the mixing product is less than 10%, the content of particles with a particle size of ≤10mm is 88%, it is not sticky when grasped by hand, and the calorific value is measured to be 9MJ / kg.

[0130] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
