Description

Technical Field

[0001] The invention relates to the technical field of Fischer-Tropsch synthesis slag wax, and in particular to an oxidation and self-ignition device for Fischer-Tropsch synthesis slag wax. Background Art

[0002] Fischer-Tropsch synthesis slag wax is a type of solid waste generated in the Fischer-Tropsch synthesis process. In the Fischer-Tropsch synthesis process, substances such as catalysts and activated clay are used. During the reaction, these substances may mix with the product paraffin to form slag wax. Slag wax mainly contains paraffin, deactivated clay, a small amount of catalyst and residue. Specifically, the catalyst solid powder content in the slag wax may reach 10-90%, and its particle size is 1-200 microns. The content of the wax component may be between 90-10%, and its melting point ranges from 80-120°C. Because the slag wax contains combustible substances such as paraffin, it is easy to accumulate heat and spontaneously combust when exposed to the air for a long time, so it is regarded as a relatively dangerous solid waste.

[0003] When the spontaneous combustion of Fischer-Tropsch slag wax is detected, the Fischer-Tropsch slag wax is placed in a specific storage device to cause the Fischer-Tropsch slag wax to spontaneously combust and dissolve. However, the existing device makes it difficult to reprocess the solid residue of the Fischer-Tropsch slag wax after the Fischer-Tropsch slag wax is dissolved, which causes the solid residue after spontaneous combustion to affect the environment.

[0016] By adopting this scheme, the Fischer-Tropsch synthesis slag wax falls from the dropping port into the dropping barrel located in the heating position (i.e., the heating chamber).

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 7As shown, an embodiment of the present invention provides a Fischer-Tropsch synthesis slag wax oxidation and self-ignition device, which includes a shell 10 and a combustion component 20, a discharge component 30 and a processing component 40 arranged in the shell 10. The top of the shell 10 has a discharge port 101, the combustion component 20 has a heating chamber and a first drainage channel connected to the bottom of the heating chamber, the combustion component 20 includes a lifting component 22 and a discharge barrel 21 with a drainage gap 212 at the bottom, the discharge barrel 21 can be raised and lowered by the lifting component 22 and has a heating position located in the heating chamber and a discharge position located above the heating chamber; the processing component 40 has a processing chamber that is interconnected and a second drainage channel connected to the bottom of the processing chamber, the processing chamber is located on one side of the discharge position and has a liquid supply channel above its opening, the discharge component 30 is rotatably arranged at the discharge position and has a clamping area for clamping the discharge barrel 21, so as to drive the discharge barrel 21 to rotate and pour the slag wax in the discharge barrel 21 and the dissolved residue into the processing chamber.

[0033] In this embodiment, the Fischer-Tropsch synthesis slag wax falls from the drop port 101 into the drop barrel 21 located in the heating position (i.e., the heating chamber). The heating of the drop barrel 21 by the heating chamber causes the Fischer-Tropsch synthesis slag wax in the drop barrel 21 to spontaneously combust and dissolve. The dissolved liquid falls from the drainage gap 212 and is discharged from the first drainage channel. The solid residue remaining after spontaneous combustion remains in the drop barrel 21. Thereafter, the drop barrel 21 is lifted as a whole to the unloading position by the lifting assembly 22 to separate the solid residue and the liquid. The drop barrel 21 at the unloading position is detachably clamped by the discharge assembly 30, and the solid residue in the drop barrel 21 is unloaded by the rotation of the discharge assembly 30. The drop barrel 21 rotates and pours the solid residue into the processing chamber. At the same time, the liquid supply channel supplies processing liquid to the inside of the processing chamber. The processing liquid processes the solid residue and is discharged from the second drainage channel together. With such arrangement, the self-ignition of the Fischer-Tropsch slag wax can be assisted (combustion-supported) by the heating chamber to ensure the reliability of its combustion and dissolution, the unloading of the blanking barrel 21 can be achieved through the lifting component 22 and the discharging component 30 to achieve timely discharge of the solid residue produced after combustion, thereby avoiding the accumulation of the solid residue in the blanking barrel 21, and the reprocessing of the solid residue can be achieved through the processing component 40 to avoid the situation where the directly discharged solid residue will affect the environment, thereby effectively reducing the impact of the Fischer-Tropsch slag wax residue on the environment.

[0034] It is understandable that the maximum width of the liquid discharge gap 212 at the bottom of the blanking barrel 21 should be smaller than the size of the solid residue to ensure the stopping effect on the solid residue. The small-sized solid residue can be directly discharged along with the liquid.

[0035] like Figure 2 , Figure 3 and Figure 5As shown, the lifting assembly 22 is two groups and symmetrically arranged on both sides of the combustion assembly 20 in the radial direction. The lifting assembly 22 includes a first drive assembly and a lifting rod group. The housing 10 has a mounting seat 11. The first drive assembly includes a first drive motor 221 arranged on the mounting seat 11 and a drive shaft 222 connected to the output end of the first drive motor 221. The lifting rod group is arranged on the drive shaft 222 and forms a triangular support area with the drive shaft 222. The outer peripheral edge of the top of the blanking barrel 21 corresponds to the two lifting assemblies 22 and is provided with two adapter blocks 211. The top of the triangular support area has a support groove for supporting the adapter block 211. The shape of the triangular support area is an isosceles triangle. The two bottoms of the triangular support area can be relatively close or far away synchronously to adjust the position of the support groove in the vertical direction. This arrangement is conducive to achieving the lifting of the blanking barrel 21 while ensuring the stable support of the blanking barrel 21. It can be understood that the support groove can directly support the adapter block 211, or it can be assisted by the adapter to support the adapter block 211.

[0036] Specifically, the lifting assembly 22 includes two groups of symmetrically arranged lifting rods 223 and sliding nuts 224. The outer periphery of the driving shaft 222 is provided with two sections of external threads at intervals along its length direction. The two sliding nuts 224 are respectively threadedly connected to the two sections of external threads. One ends of the two lifting rods 223 are respectively hinged to the corresponding sliding nuts 224, and the other ends of the two lifting rods 223 are hinged to each other to form a support groove for supporting the adapter block 211.

[0037] In this embodiment, when the position of the blanking barrel 21 in the vertical direction needs to be adjusted, the first drive motor 221 is started, and the first drive motor 221 drives the drive shaft 222 to rotate. Due to the threaded connection between the sliding nut 224 and the outer periphery of the drive shaft 222, the two sliding nuts 224 located on the same drive shaft 222 will move relative to each other synchronously and adjust the height of the triangular support area, thereby realizing the adjustment of the position of the blanking barrel 21 in the vertical direction. This arrangement facilitates the rapid adjustment of the triangular support area, and improves the convenience of adjustment on the basis of ensuring the reliability of adjustment.

[0038] It can be understood that the two groups of lifting components 22 are started and stopped synchronously to ensure effective lifting and support of the blanking barrel 21 .

[0039] Furthermore, the lifting assembly 22 further includes a limiting rod 225, which is fixedly arranged on the mounting seat 11 and passes through the two sliding nuts 224. This arrangement prevents the sliding nut 224 from rotating around the axis of the driving shaft 222, thereby ensuring the reliability and stability of the sliding thread of the sliding nut 224.

[0040] It is understandable that any one of the lifting assemblies 22 includes at least two limiting rods 225 to enhance the limiting effect of the limiting rods 225 on the sliding nut 224 .

[0041] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the discharge assembly 30 includes a limit block group, a clamping support assembly and a second drive assembly. The limit block group is located above the heating chamber and is arranged around the unloading position. The limit block group has at least a guide gap 301 for avoiding the lifting assembly 22 and the blanking barrel 21 from rising and falling. The clamping support assembly is arranged below the limit block group and has a plurality of rotatable clamping support ends. When the plurality of clamping support ends are rotated into the opening below the unloading position, the plurality of clamping support ends jointly support the bottom of the blanking barrel 21 in the unloading position. The second drive assembly is arranged in the shell 10 and is drivingly connected to the limit block group to drive the limit block group to rotate and drive the blanking barrel 21 to unload.

[0042] In this way, by setting the guide gap 301, it is avoided that the limit block group will block the lifting of the blanking barrel 21, and the reliability of lifting the blanking barrel 21 is ensured. The blanking barrel 21 is supported by multiple clamping support ends, and it is avoided that the blanking barrel 21 will fall out from the bottom of the limit block group when the blanking barrel 21 needs to be rotated to discharge, and the reliability of rotation discharge is ensured.

[0043] The second driving assembly drives the limit block group to rotate at an angle greater than 90° to ensure the dumping effect of the solid residue in the blanking barrel 21 .

[0044] Specifically, the limit block group includes multiple limit blocks 31 and multiple transfer rods 32. When the limit block group surrounds the unloading position, the multiple limit blocks 31 are distributed at intervals along the circumference of the blanking barrel 21. The second driving assembly is drivingly connected to at least one limit block 31 on the side close to the processing assembly 40. The tops of every two limit blocks 31 are connected by a transfer rod 32, and a transfer rod 32 is correspondingly arranged above any guide gap 301. The multiple clamping support ends of the clamping support assembly are distributed at the bottom of the multiple limit blocks 31.

[0045] This arrangement facilitates the second driving assembly to drive the overall rotation of the limit block group, and further facilitates the driving of the blanking barrel 21 mounted inside the limit block group. At the same time, a transfer rod 32 is correspondingly arranged above any guide gap 301 to limit the lifting height of the blanking barrel 21, and the reliability and stability of the clamping of the blanking barrel 21 are further improved in conjunction with the multiple clamping support ends arranged at the bottom.

[0046] Furthermore, the card-mounted support assembly includes multiple rotating motors 33 and a support plate 34 fixedly arranged at the output end of the rotating motor 33. A rotating motor 33 is correspondingly embedded in any one of the limit blocks 31. The support plate 34 is located at the bottom of the limit block 31. Any one of the support plates 34 forms a corresponding card-mounted support end; the second drive assembly includes a second drive motor 35 and a drive rod 36 fixedly connected to the end of the second drive motor 35. The drive rod 36 passes through at least one limit block 31 and is fixedly connected to the limit block 31.

[0047] In this embodiment, the limit block group includes four limit blocks 31 and two transfer rods 32, wherein the two limit blocks 31 are located on a side close to the processing component 40, and the tops of the two limit blocks 31 on this side are respectively connected to the tops of the other two limit blocks 31 through two transfer rods 32, and two guide gaps 301 for avoiding the transfer blocks 211 are formed between the two limit blocks 31 on this side and the other two limit blocks 31. Correspondingly, there are four rotating motors 33, and the four rotating motors 33 are respectively embedded in the bottom of the four limit blocks 31 and the output ends protrude from the bottom of the limit blocks 31. There are four support plates 34 and they are respectively fixedly mounted on the output ends of the four rotating motors 33. The four support plates 34 can rotate synchronously, that is, they simultaneously avoid the bottom opening of the area enclosed by the limit block group or simultaneously rotate to below the bottom opening of the area enclosed by the limit block group. With this arrangement, the blanking barrel 21 that rises to the unloading position can be limited by four limit blocks 31, and the blanking barrel 21 can be clamped in the limit block group by two transfer rods 32 and four support plates 34, thereby ensuring the reliability of lifting and rotating unloading.

[0048] In this embodiment, the combustion assembly 20 further includes a heating cylinder 23 and a first liquid discharge pipe 24 connected to the bottom of the heating cylinder 23. The area inside the heating cylinder 23 forms a heating chamber, and the area inside the first liquid discharge pipe 24 forms a first liquid discharge channel. The radial dimension of the bottom of the heating cylinder 23 gradually decreases in the direction from the heating cylinder 23 to the first liquid discharge pipe 24. The end of the first liquid discharge pipe 24 that is away from the heating cylinder 23 passes through the shell 10. The top of the shell 10 also has a smoke exhaust port 102 for exhausting smoke generated by combustion. It can be understood that the number and setting position of the smoke exhaust port 102 can be adaptively adjusted according to actual conditions.

[0049] The shape of the blanking barrel 21 in this embodiment is adapted to the heating barrel 23, so as to improve the heating effect of the heating barrel 23 on the blanking barrel 21. The radial dimension of the bottom of the heating barrel 23 is limited, which is conducive to promoting the movement of the fluid and avoiding accumulation. On the other hand, the smoke in the housing 10 is discharged through the smoke exhaust port 102 to avoid accumulation affecting the structure or ambient temperature in the housing.

[0050] Among them, the Fischer-Tropsch synthesis slag wax oxidation self-ignition device also includes a first heating component, a temperature monitoring module 50 and a control module. The first heating component is arranged in the heating chamber to heat the heating chamber. The temperature monitoring module 50 is electrically connected to the heating chamber to monitor the actual temperature in the heating chamber. The control module is electrically connected to the temperature monitoring module 50 and the first heating component to adjust the first heating component according to the temperature conditions monitored by the temperature monitoring module 50; the control module is electrically connected to the lifting component 22 and the discharge component 30 to control the lifting, clamping support and rotation unloading of the blanking barrel 21.

[0051] In this way, the self-ignition temperature of the Fischer-Tropsch synthesis slag wax is monitored by the temperature monitoring module 50, which is conducive to ensuring the safety of the self-ignition of the Fischer-Tropsch synthesis slag wax and reducing the heating cost. At the same time, understanding the conditions and mechanism of the self-ignition of the Fischer-Tropsch synthesis slag wax when storing the Fischer-Tropsch synthesis slag wax is helpful to optimize the production process, and to timely discover and solve potential quality problems, thereby ensuring the stability and reliability of the product.

[0052] On the other hand, the electrical connection between the control module and the first heating component, the lifting component 22 and the discharge component 30 facilitates the operator to semi-automatically control the Fischer-Tropsch synthesis slag wax oxidation self-ignition device, thereby improving the convenience of operation.

[0053] Preferably, the temperature monitoring module 50 is a thermocouple, which is fixedly mounted on the mounting seat 11 in the housing 10, and the detection end of the thermocouple contacts the outer periphery of the heating cylinder 23, so as to monitor the temperature in the heating chamber, so as to monitor the spontaneous combustion temperature of the Fischer-Tropsch slag wax. The first heating component is an electric heating wire laid on the inner wall of the heating chamber. It can be understood that the Fischer-Tropsch slag wax oxidation spontaneous combustion device also includes a power supply for powering electrical equipment such as the electric heating wire.

[0054] It is understandable that the selection of the temperature monitoring module 50 can be adaptively adjusted according to actual conditions and is not limited to thermocouples, which are not exemplified here. A heat insulation board is installed at the outer position of the housing 10 near the first drive motor 221 to isolate the high temperature generated by the first heating component.

[0055] like Figures 1 to 3 as well as Figure 6As shown, the treatment component 40 includes a first liquid storage tank 41, a second liquid storage tank 42, a second heating component, a treatment cylinder 43 and a second liquid discharge pipe 44 connected to the bottom of the treatment cylinder 43. The area inside the treatment cylinder 43 forms a treatment chamber, and the area inside the second liquid discharge pipe 44 forms a second liquid discharge channel. The first heating component is arranged in the treatment chamber to heat the treatment chamber. The radial dimension of the bottom of the treatment cylinder 43 gradually decreases in the direction of the treatment cylinder 43 toward the second liquid discharge pipe 44. The end of the second liquid discharge pipe 44 away from the treatment cylinder 43 passes through the shell 10. The first liquid storage tank 41 and the second liquid storage tank 42 are spaced apart at the top of the shell 10 and are used to store water and catalyst respectively. The bottoms of the first liquid storage tank 41 and the second liquid storage tank 42 are both connected with a liquid drop pipe 45. The openings of the two liquid drop pipes 45 are both located above the treatment chamber and facing the treatment chamber. The areas inside the first liquid storage tank 41, the second liquid storage tank 42 and the liquid drop pipe 45 form a liquid supply channel. With this arrangement, the operator can add catalyst and water to the processing chamber while pouring the solid residue into the processing chamber, thereby realizing the reprocessing of the solid residue and avoiding the direct discharge of the solid residue and the impact on the environment. On the other hand, the heating in the heating chamber is realized by the second heating component, and the hydrolysis liquid is heated to a certain degree to perform a hydrolysis reaction. During the hydrolysis process, the organic matter reacts with water to generate a hydrolysis product, further improving the treatment effect of the solid residue. Preferably, the second heating component is an electric heating wire laid on the inner wall of the processing chamber.

[0056] It is understandable that the type and amount of the catalyst can be selected according to the amount of specific residue and reaction conditions, and the catalyst can be an acid or a base. In this embodiment, a solenoid valve can be provided at the first drain pipe 24 and the second drain pipe 44 to control the opening and closing of the first drain channel and the second drain channel.

[0057] Among them, spontaneous combustion of Fischer-Tropsch slag wax will produce CO, CO2, C2H4, and C2H6. Specifically, CO is produced during spontaneous combustion of Fischer-Tropsch slag wax, and during the oxidation and heating of Fischer-Tropsch slag wax, the CO generation rate does not change significantly with the fluctuation of gas temperature before 120°C. When the temperature exceeds 120°C, the CO generation of each coal sample increases rapidly. Specifically, when the temperature is less than 90°C, the temperature of the slag wax is relatively low, and the reaction between the slag wax molecules and oxygen is mainly physical adsorption, and the reaction proceeds slowly, resulting in the amount of CO generated not changing significantly with temperature. After the temperature gradually rises to 120°C, the oxidation reaction of the slag wax is mainly chemical adsorption and chemical reaction, and the reaction intensity between the slag wax molecules and oxygen will become more intense, increasing the amount of CO generated, and causing the amount of CO generated to show an exponential increase trend with temperature. Among them, according to the changing trend of CO generation with temperature, it can be concluded that CO gas can be used as an indicator gas for predicting the spontaneous combustion process of slag wax. The variation trend of CO2 production in Fischer-Tropsch slag wax with temperature is similar to that of CO, which also shows a trend of first slowly rising and then exponentially increasing. Comparing the production of CO and CO2 under the same conditions, it is found that the production of CO2 is much higher than that of CO. This is because CO is the product of incomplete oxidation of coal, and part of CO will also be oxidized to form CO2 during the spontaneous combustion of coal. Therefore, the production of CO2 in the coal sample during the low-temperature oxidation process is much higher than that of CO. When the Fischer-Tropsch slag wax is dissolved, no C2H4 gas is detected in the initial stage of low-temperature oxidation, which indicates that there is no C2H4 gas in the pores of the slag wax. It also shows that the reaction of slag wax with oxygen at a lower temperature (<90°C) will not generate C2H4 gas. As the temperature of the slag wax continues to rise, the concentration of C2H4 is also gradually and rapidly increasing, and the concentration shows a monotonically increasing trend. When the slag wax temperature exceeds 120°C, the concentration of C2H4 gas will increase rapidly. A small amount of C2H6 gas is produced in the initial stage of dissolution of Fischer-Tropsch slag wax, and the C2H6 concentration gradually increases with the increase of slag wax temperature. Unlike CO and CO2 gases, the change trend of C2H6 gas with increasing temperature in the low temperature stage (<90°C) is relatively obvious.

[0058] In summary, the present invention provides a Fischer-Tropsch synthesis slag wax oxidation self-ignition device. When in use, the Fischer-Tropsch synthesis slag wax to be treated is placed in the blanking barrel 21 through the blanking port 101. At this time, the first heating component (electric heating wire) starts to auxiliary heat the heating chamber in the heating barrel 23. The Fischer-Tropsch synthesis slag wax is in a dissolved state. The temperature monitoring module 50 (thermocouple) detects the temperature in the heating barrel 23 to determine the temperature at which the Fischer-Tropsch synthesis slag wax is dissolved. The liquid produced by the dissolution will fall from the drainage gap 212 and be discharged through the first drainage pipe 24 (first drainage channel). The solid residue is stored in the blanking barrel 21. The smoke generated during the dissolution process is discharged from the smoke exhaust port 102. After that, the first drive motors 221 of the two lifting components 22 both drive the drive shaft 222 to rotate. The two sliding nuts 224 of the same lifting component 22 approach each other to adjust the triangular support area. The two sliding nuts 224 drive the drop through the cooperation of the lifting rod 223 and the adapter block 211. The barrel 21 moves up to the unloading position, and the blanking barrel 21 is separated from the heating barrel 23 until the blanking barrel 21 completely enters the bottom of the limit block group or the top of the blanking barrel 21 abuts against the transfer rod 32, and the rotating motor 33 is started to drive the support plate 34 to rotate. Multiple support plates 34 rotate to the bottom opening of the limit block group and support the bottom of the blanking barrel 21. Then, the second drive motor 35 drives the drive rod 36 to rotate and drives the limit block group as a whole and the blanking barrel 21 clamped inside the limit block group to rotate together, and the rotation angle exceeds 90°, so as to dump the solid residue in the blanking barrel 21 into the processing barrel 43. At the same time, the water inside the first liquid storage tank 41 flows into the processing barrel 43 and mixes with the residue. The catalyst inside the second liquid storage tank 42 is injected into the processing barrel 43 to form a hydrolyzate. Then, the second heating component (electric heating wire) is started to heat the hydrolyzate to a certain degree to perform a hydrolysis reaction. During the hydrolysis process, organic matter reacts with water to generate hydrolysis products.

[0059] Compared with the prior art, this embodiment sets up a temperature monitoring module 50, thereby clarifying the auto-ignition temperature of the Fischer-Tropsch slag wax during use, improving safety protection when storing the Fischer-Tropsch slag wax, reducing costs, and improving the economic benefits of the enterprise. At the same time, understanding the conditions and mechanism of auto-ignition of the Fischer-Tropsch slag wax when storing the Fischer-Tropsch slag wax is helpful to optimize the production process, and can timely discover and solve potential quality problems, thereby ensuring the stability and reliability of the product; further, through the mutual cooperation of the combustion component 20, the discharge component 30 and the processing component 40, when the Fischer-Tropsch slag wax is detected for auto-ignition, the combustion component 20 can assist the combustion of the Fischer-Tropsch slag wax, and then the dissolved residue is poured into the processing component 40 through the discharge component 30, and then the Fischer-Tropsch slag wax residue can be processed in the processing component 40, effectively reducing the impact of the Fischer-Tropsch slag wax residue on the environment and saving valuable resources.

[0060] Preferably, the solid residue of Fischer-Tropsch synthesis slag wax can also be first subjected to thermochemical treatment, and then the treated residue is calcined at high temperature and then cooled to obtain a crude catalyst, and then the crude catalyst is washed with an organic solvent and dried. The crude catalyst after washing and drying can be acid-washed and its pH value is adjusted to 6.5-7.5, and then the product is dried to obtain a catalyst for water treatment.
