Description

Technical Field

[0001] The invention relates to the technical field of waste treatment in organosilicon production, and in particular to waste treatment equipment in organosilicon production. Background Art

[0002] The slurry residue formed during the production of silicone is mostly high-boiling substances and a small amount of chlorosilane monomers, as well as some silicon powder and catalysts.

[0003] At present, high-temperature cracking method is used to treat the pulp residue formed in the production process of organosilicon. The high-temperature cracking method usually requires the use of a reactor. During the operation, the temperature in the reactor will be raised to a high temperature range of 300-900℃. When such temperature conditions are reached, the Si-Si bond inside the high-boiling product will break, and then produce gaseous silane monomers. This high-temperature cracking method has unique advantages. On the one hand, it has relatively loose requirements on raw materials. When treating high-boiling products such as waste materials from organosilicon production, it is not necessary to remove some of the solid impurities in advance. On the other hand, it can crack almost all silanes and has a wide range of applicability.

[0004] However, when the slurry residue formed in the production process of silicone is treated by high-temperature pyrolysis, the temperature is high, and a lot of carbon deposits will form on the inner wall of the reactor.

[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] like Figure 1 and Figure 4 As shown, the present invention provides a waste treatment device for silicone production, including a supporting mechanism 1, a reaction mechanism 2 and a rotating mechanism 3. The reaction mechanism 2 includes a reaction tube 21 and a heating component 22. The reaction tube 21 is connected to the supporting mechanism 1. The reaction tube 21 has a feed port, a discharge port and an exhaust port. The heating component 22 is connected to the reaction tube 21 for heating the reaction tube 21. The rotating mechanism 3 includes a rotating shaft 31, an auger component 32 and a driving component 33. The rotating shaft 31 can rotate through the reaction tube 21. The auger component 32 is built into the reaction tube 21 and connected to the rotating shaft 31. The driving component 33 is connected to the rotating shaft 31 and the supporting mechanism 1 for driving the rotating shaft 31 to rotate.

[0043] The slurry formed in the production process of organic silicon is introduced into the reaction tube 21 through the feed port, and the reaction tube 21 is heated by the heating component 22, and the temperature of the slurry in the reactor is controlled at 300-900°C. The slurry is reacted and cracked into gaseous silane monomers in the reaction tube 21, and the silane monomers are discharged from the exhaust port; during the heating process of the heating component 22, the driving component 33 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the auger component 32 to rotate. The auger component 32 can scrape off the attachments on the inner wall of the reaction tube 21 to avoid carbon deposition on the inner wall of the reaction tube 21 and affect heat transfer. At the same time, the rotating auger component 32 can push the material to move from the feed port to the discharge port, and can discharge the substances formed in the high-temperature cracking reaction process from the discharge port.

[0044] Taking the temperature of 500° C. as an example, at this time, the slurry formed in the production process of organic silicon is cracked to form methyltrichlorosilane and dimethylsilane; it should be understood that when the slurry is treated by high-temperature cracking reaction, some additives can be added to the reaction tube 21 to promote the reaction.

[0045] In order to collect the gaseous products formed during the high-temperature cracking process, for this purpose, such as Figure 1 and Figure 3 As shown, in one of the embodiments, the waste treatment equipment for silicone production also includes a condensation mechanism 4, which includes a condenser 41 and an exhaust assembly 42, the air inlet end of the condenser 41 is connected to the exhaust port, and the air inlet end of the exhaust assembly 42 is connected to the air outlet end of the condenser 41.

[0046] During the high-temperature cracking of the slurry, gaseous silane monomers are formed, and the exhaust component 42 is started to exhaust the gas in the reaction tube 21 outward. When the gas passes through the condenser 41, the gaseous silane monomers are pre-cooled and liquefied to form a liquid product, which can separate the silane monomers from the gas. The gas extracted by the exhaust component 42 is subsequently discharged after harmless treatment.

[0047] It should be understood that the condenser 41 may be a water-cooled condenser 41, an evaporative condenser 41, a plate condenser 41, etc.; the exhaust component 42 may be an exhaust fan, an exhaust pump, etc.

[0048] It should be understood that the condenser 41 has a drain port at the bottom, through which the liquefied product is discharged.

[0049] It should be understood that the heating component 22 can be an electric heating tube, a steam heating jacket, a gas heating device, etc.; the number of the heating components 22 can be one or more, etc. In one embodiment, the number of the heating components 22 is multiple, and the multiple heating components 22 are distributed at intervals along the circumference of the reaction tube 21.

[0050] It should be understood that the reaction tube 21 can be made of quartz, stainless steel, etc.; the cross section of the reaction tube 21 can be circular, square, polygonal, etc.

[0051] In order to break up the material being transported by the auger assembly 32, Fig.12 As shown, in one embodiment, the auger assembly 32 includes at least one first auger 321 and at least one second auger 322. The first auger 321 and the second auger 322 are both connected to the reaction tube 21 and are arranged at intervals. The first auger 321 and the second auger 322 have opposite rotation directions.

[0052] By setting the first auger 321 and the second auger 322, the first auger 321 pushes the pulp residue to move from the feed port toward the discharge port in the reaction tube 21. During the process of the first auger 321 pushing the pulp residue to move, the pulp residue is squeezed and compressed. When the pulp residue moves to the second auger 322, since the rotation direction of the second auger 322 is opposite to that of the first auger 321, it will push the pulp residue in the reverse direction, which can break up the compressed pulp residue and make it fluffy, so as to facilitate uniform heating of the pulp residue, accelerate the speed of high-temperature cracking of the pulp residue, and avoid incomplete reaction.

[0053] It should be understood that the first auger 321 and the second auger 322 may be spiral bars.

[0054] Since it is necessary to push the pulp residue from the feed port to the discharge port through the auger assembly 32, for this purpose, Fig.12As shown, in one embodiment, the pitch of the first auger 321 is smaller than that of the second auger 322 , and the axial length of the first auger 321 along the rotating shaft 31 is greater than that of the second auger 322 .

[0055] Through the above arrangement, when the rotating shaft 31 rotates, it will synchronously drive the first auger 321 and the second auger 322 to rotate. Since the pitch of the first auger 321 is smaller than that of the second auger 322, and the length of the first auger 321 is greater than that of the second auger 322, the driving force applied to the pulp by the first auger 321 is greater than the driving force applied to the pulp by the second auger 322. While the second auger 322 breaks up the pulp, the pulp can pass through the second auger 322 under the push of the first auger 321, so that the pulp can move along the axial direction of the rotating shaft 31 under the push of the auger assembly 32, so that the pulp can move smoothly from the feed port to the discharge port.

[0056] It should be understood that the first auger 321 and the second auger 322 in the auger assembly 32 may be one, two or more. Fig.12 As shown, in one of the embodiments, there are multiple first auger 321 and multiple second auger 322, and multiple second auger 322 are combined to form a second auger 322 unit. The number of second auger 322 units in the auger assembly 32 is multiple, and multiple second augers 322 in the second auger 322 unit are distributed at intervals along the circumference of the rotating shaft 31, and the second auger 322 units and the first auger 321 are alternately distributed along the axial direction of the rotating shaft 31.

[0057] In this embodiment, the first auger 321 adopts a small pitch + long stroke design to form a high compression ratio conveying section. By increasing the spiral angle, the axial movement speed of the material is reduced, so that a greater axial thrust is obtained per unit length, which is particularly suitable for processing high-viscosity, easy-to-sediment slurry materials; the second auger 322 unit adopts a large pitch with a circumferential multi-spiral structure to form a discrete processing section. Its increased radial component can realize centrifugal diffusion of the material, and cooperate with the circumferentially distributed multiple second augers 322 to form a shear field, which effectively solves the material agglomeration phenomenon; the first auger 321 and the second auger 322 units that are alternately distributed axially The elements form a pulsating conveying mode from compression to release, wherein pressure accumulates at the first auger 321, and the pressure is reduced by multi-spiral diversion at the second auger 322 unit, which prevents blockage caused by excessive compression and maintains the pressure gradient required for continuous conveying; the second auger 322 units distributed at circumferential intervals form an asymmetric flow field, and their circumferential phase difference θ=360° / n (when n≥3) can generate vortex secondary flow, which makes the material self-cleaning while moving axially. Actual measurements show that this design can reduce the wall residue by 42%; the system aspect ratio can be flexibly adjusted by increasing or decreasing the number of alternating units.

[0058] In order to drive the pulp residue to move along the axial direction of the reaction tube 21 through the first auger 321, the pitch of the first auger 321 needs to be set relatively small. The relatively small pitch will result in a relatively small distance between adjacent spirals of the first auger 321. During the high-temperature cracking process, carbon may accumulate and pulp residue may adhere in the gap between adjacent spirals of the first auger 321. For this reason, Figures 4 to 11 As shown, in one embodiment, the reaction tube 21 has an opening relative to the first auger 321; the reaction mechanism 2 also includes a cleaning component 23, the cleaning component 23 includes a sliding portion 231, a plurality of cleaning portions 232 and a driving member 233, the sliding portion 231 is slidably connected to the outer wall of the reaction tube 21 along the axial direction of the reaction tube 21, and slides to close the opening, the sliding portion 231 has a plurality of slots connected to the reaction tube 21, the plurality of cleaning portions 232 are slidably inserted in the plurality of slots, the plurality of cleaning portions 232 are used to be inserted into the gap of the first auger 321 to clean the gap of the first auger 321, and the driving member 233 connects the reaction tube 21 and the plurality of cleaning portions 232, and is used to drive the plurality of cleaning portions 232 to slide in and out of the reaction tube 21.

[0059] When it is necessary to clean the first auger 321, stop feeding into the feed port of the reaction tube 21, and then start the driving member 233. The driving member 233 drives the cleaning portion 232 to slide relative to the slot and slide into the reaction tube 21, and the cleaning portion 232 is inserted into the gap between adjacent spirals in the first auger 321. The driving component 33 is started. The driving component 33 drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the first auger 321 to rotate. The first auger 321 squeezes the cleaning portion 232. Since the cleaning portion 232 is connected to the reaction tube 21 by sliding along the axial direction of the reaction tube 21 through the sliding portion 231, the first auger 321 pushes the cleaning portion 232 to move along the axial direction of the reaction tube 21, and the first auger 321 rotates relative to the cleaning portion 232. The cleaning portion 232 cleans the rotating first auger 321. After cleaning, the cleaning portion 232 is driven to slide out of the reaction tube 21 by the driving member 233.

[0060] By setting the sliding part 231, the sliding part 231 is slidably connected with the reaction tube 21. The sliding part 231 can allow the cleaning part 232 to slide in and out of the reaction tube 21, and the cleaning part 232 can drive the sliding part 231 to move along the axial direction of the reaction tube 21. When the sliding part 231 slides, it can always seal the opening of the reaction tube 21 to prevent the slurry residue in the reaction tube 21 from overflowing out of the opening; at the same time, when the driving part 233 drives the cleaning part 232 to slide out of the reaction tube 21, it is always inserted in the slot and closes the slot to prevent the slurry residue from overflowing out of the slot.

[0061] It should be understood that the opening is located at the top of the reaction tube 21, and may also be located at other positions.

[0062] It should be understood that the sliding part 231 can be slidably connected to the reaction tube 21 through a sliding groove and a slider, or a limit rod can be provided on the reaction tube 21 to limit the sliding direction of the sliding part 231 to prevent the sliding part 231 from rotating relative to the reaction tube 21.

[0063] It should be understood that the driving member 233 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0064] It should be understood that the plurality of slots on the sliding portion 231 are spaced apart along the axial direction of the reaction tube 21 , and the cleaning portions 232 may correspond to the slots one by one, or a plurality of cleaning portions 232 may be inserted into one slot.

[0065] It should be understood that when the multiple cleaning parts 232 clean the gaps in the spiral of the first auger 321 , the greater the number of cleaning parts 232 , the smaller the distance the multiple cleaning parts 232 need to move when cleaning the gaps in the first auger 321 .

[0066] It should be understood that the sizes of the multiple cleaning parts 232 can be the same or different, and the cleaning parts 232 can be block-shaped, rod-shaped, etc. Specifically, in one embodiment, the sizes of the multiple cleaning parts 232 gradually increase along the conveying direction of the first auger 321, and the increase in size is a gradual increase in the size along the axial direction of the reaction tube 21.

[0067] In this embodiment, multiple cleaning parts 232 clean the gap in the first auger 321 in turn, and because the size is gradually increased, the gap in the first auger 321 can be cleaned gradually, and the cleaning force is gradually increased to avoid excessive single cleaning force causing the cleaning part 232 to get stuck in the first auger 321.

[0068] Since the first auger 321 pushes the cleaning part 232 to move along the axial direction of the reaction tube 21, the cleaning part 232 needs to slide relative to the driving member 233. Figure 4 and Figure 8 As shown, in one embodiment, the cleaning assembly 23 also includes a connecting portion 234, which connects the multiple cleaning portions 232; the driving member 233 is slidably connected to the connecting portion 234 along the axial direction of the reaction tube 21, and is connected to the multiple cleaning portions 232 through the connecting portion 234, and can drive the multiple cleaning portions 232 to slide in and out of the reaction tube 21 through the connecting portion 234.

[0069] In this embodiment, by providing a connecting portion 234, the driving member 233 can drive multiple cleaning portions 232 to slide in and out of the reaction tube 21 through the connecting portion 234. When the cleaning portion 232 cleans the first auger 321, the first auger 321 will push the cleaning portion 232 to move along the axial direction of the reaction tube 21, so that the cleaning portion 232 drives the connecting portion 234 to move along the axial direction of the reaction tube 21, and drives the connecting portion 234 to slide relative to the driving member 233, so that the driving member 233 can drive the cleaning portion 232 to slide in and out of the reaction tube 21 through the connecting portion 234, and can avoid the driving member 233 from obstructing the connecting portion 234 and the cleaning portion 232.

[0070] When the cleaning portion 232 cleans the first auger 321, the first auger 321 drives the connecting portion 234 to move along the axial direction of the reaction tube 21. After the cleaning portion 232 completes the cleaning of the first auger 321, the first auger 321 will push the connecting portion 234 and the reaction tube 21 to continue sliding. When the cleaning portion 232 slides and abuts the second auger 322, since the second auger 322 and the first auger 321 have opposite rotation directions, the second auger 322 will push the cleaning portion 232 and the connecting portion 234 to move in the opposite direction, so that the cleaning portion 232 is subjected to two opposite forces until it is destroyed. In order to avoid the cleaning portion 232 from being destroyed, for this purpose, Figure 4 and Figure 5 As shown, in one of the embodiments, the reaction mechanism 2 also includes a limiting component 24, which is arranged on the moving path of the connecting part 234 or the sliding part 231, and is electrically connected to the driving member 233. When the connecting part 234 or the sliding part 231 slides and abuts against the limiting component 24, the connecting part 234 controls the movement of the driving member 233, and enables the driving member 233 to drive the multiple cleaning parts 232 to slide out of the reaction tube 21.

[0071] By setting a limit component 24, the limit component 24 is set on the moving path of the connecting part 234 or the sliding part 231. When the cleaning part 232 cleans the first auger 321, it will push the connecting part 234 and the sliding part 231 to gradually approach the limit component 24. When the sliding part 231 or the connecting part 234 abuts against the limit component 24, the limit component 24 controls the driving member 233 to move, and the driving member 233 drives the multiple cleaning parts 232 to slide out of the reaction tube 21 through the connecting part 234, so as to prevent the cleaning part 232 from sliding and abutting against the second auger 322.

[0072] It should be understood that the limit assembly 24 can be a limit switch, a travel switch 241, a photoelectric switch, etc.

[0073] By providing the travel switch 241 , when the connecting portion 234 or the sliding portion 231 slides and abuts against the travel switch 241 , the travel switch 241 is triggered, and the travel switch 241 drives the plurality of cleaning portions 232 to slide out of the reaction tube 21 .

[0074] Since the limiting assembly 24 is located outside the reaction tube 21, it will be corroded by the temperature of the reaction tube 21 and may fail. Figures 4 to 11 As shown, in one embodiment, the cleaning component 23 also includes a fixed seat 235 and a limiting seat 236, the fixed seat 235 is connected to the plurality of cleaning parts 232, the limiting seat 236 is connected to the reaction tube 21, and the reaction mechanism 2 also includes a mechanical limiting structure 25, the mechanical limiting structure 25 includes a plurality of sleeves 251, a plurality of limiting rods 252, a slide bar 253, at least one first elastic part 254 and at least one second elastic part 255, the sleeve 251 is connected to the fixed seat 235, and a through hole is radially opened on the peripheral wall of the sleeve 251, one end of the limiting rod 252 is slidably inserted in the sleeve 251, and the other end is connected to the connecting part 234, the connecting part 234 is connected to the plurality of cleaning parts 232 via the limiting rod 252, the sleeve 251, and the fixed seat 235, and the slide bar 253 is relatively The limit seat 236 is provided and slidably inserted in turn into the through holes of the multiple sleeves 251. The slide bar 253 has multiple through slots 253a relative to the limit rod 252. The multiple through slots 253a correspond to the limit rod 252 one by one. The multiple through slots 253a are spaced apart along the length direction. The through slots 253a can allow the limit rod 252 to pass through. The slide bar 253 blocks the limit rod 252 from sliding close to the fixed seat 235. After the slide bar 253 slides, the through slot 253a slides to the corresponding limit rod 252, so that the limit rod 252 can slide through the through slot 253a. The first elastic portion 254 connects the fixed seat 235 and the connecting portion 234, and is used to provide elastic force for the fixed seat 235 and the connecting portion 234 to approach each other. The second elastic portion 255 connects the slide bar 253 and the sleeve 251.

[0075] When the limiting assembly 24 fails, the sliding portion 231 or the connecting portion 234 slides against the limiting assembly 24, and the sliding portion 231 and the connecting portion 234 continue to slide, and the slide bar 253 abuts against the fixed seat 235. The slide bar 253 slides relative to the sleeve 251 under the obstruction of the fixed seat 235 until the through groove 253a of the slide bar 253 slides to the relative limiting rod 252. At this time, the elastic restoring force of the first elastic portion 254 drives the limiting rod 252 to pass through the sleeve 251 and further insert into the sleeve 251. In the sleeve 251, under the action of the elastic restoring force of the first elastic part 254, the fixing seat 235 and the multiple cleaning parts 232 are driven to slide out of the reaction tube 21. When the limiting component 24 fails, the cleaning part 232 can be driven to slide out of the reaction tube 21, and the cleaning part 232 continues to move and abuts against the second auger 322. By setting the second elastic part 255, the second elastic part 255 can drive the slide bar 253 to be in a position to block the limiting rod 252 when the sliding sleeve is not subjected to external force.

[0076] After the mechanical limiting structure 25 is set, when the connecting portion 234 or the sliding portion 231 slides against the limiting component 24, if the limiting component 24 is stably fixed, the limiting component 24 will block the sliding of the connecting portion 234 and the sliding portion 231. Figure 7 As shown, in one embodiment, the limit assembly 24 includes a travel switch 241 and a third elastic portion 242 , the travel switch 241 is arranged on the sliding path of the connecting portion 234 or the sliding portion 231 , and the third elastic portion 242 connects the cleaning portion 232 and the travel switch 241 .

[0077] By setting the travel switch 241, when the connecting part 234 or the sliding part 231 slides and abuts against the travel switch 241, the travel switch 241 controls the action of the driving member 233, and the driving member 233 drives the cleaning part 232 to slide out of the reaction tube 21; by setting the third elastic part 242, when the travel switch 241 fails, the third elastic part 242 can allow the connecting part 234, the sliding part 231 and the travel switch 241 to slide when the travel switch 241 is abutted, so as to prevent the travel switch 241 from hindering the continued movement of the connecting part 234 and the sliding part 231.

[0078] When the cleaning part 232 cleans the first auger 321, the first auger 321 pushes the cleaning part 232 to slide along the axial direction of the reaction tube 21. When the connecting part 234 or the sliding part 231 slides and abuts the limiting component 24, the driving part 233 drives the cleaning part 232 to slide out of the reaction tube 21. At this time, the sliding part 231, the connecting part 234 and the cleaning part 232 are at a certain distance from the initial position. In order to facilitate the next cleaning of the first auger 321, in one of the embodiments, the cleaning component 23 also includes a first elastic member 237. The first elastic member 237 is connected to the connecting part 234 and / or the sliding part 231, and is also connected to the reaction tube 21, and is used to provide elastic force for the sliding part 231 and the connecting part 234 to reset after sliding.

[0079] In this embodiment, by providing the first elastic member 237, when the cleaning portion 232 cleans the first auger 321, the first auger 321 pushes the cleaning portion 232, the sliding portion 231 and the connecting portion 234 to slide along the axial direction of the reaction tube 21. During the sliding process of the cleaning portion 232, the sliding portion 231 and the connecting portion 234, the first elastic member 237 is stretched. The first elastic member 237 is stretched and accumulates elastic restoring force. When the driving member 233 drives the cleaning portion 232 to slide out of the reaction tube 21, the cleaning portion 232 is disengaged from the first auger 321, and the cleaning portion 232 loses the force pushed away from the initial position by the first auger 321. At this time, the elastic restoring force of the first elastic member 237 acts, and the first elastic member 237 pushes the sliding portion 231, the cleaning portion 232 and the connecting portion 234 to slide and reset, so as to facilitate the next time the driving member 233 drives the cleaning portion 232 to clean the first auger 321.

[0080] It should be understood that the first elastic member 237 can be a spring, an elastic strip, an elastic rod, etc.

[0081] It should be understood that the first elastic member 237 can be directly connected to the reaction tube 21 or indirectly connected to the reaction tube 21. In one embodiment, the first elastic member 237 is connected to the insulation component 26 and connected to the reaction tube 21 via the insulation component 26.

[0082] When the reaction tube 21 is heated by the heating assembly 22, in order to prevent heat from leaking outward, Figure 2 and Figure 4 As shown, in one embodiment, the reaction mechanism 2 further includes a heat insulating component 26, which is sleeved on the reaction tube 21 and forms a fixed cavity with the reaction tube 21; the heating component 22 is built in the fixed cavity.

[0083] In this embodiment, by setting up the insulation component 26, the insulation component 26 and the reaction tube 21 form a fixed cavity, and the heating component 22 is built into the fixed cavity. The heat generated by the heating component 22 during heating can be confined in the fixed cavity, reducing heat loss to the outside.

[0084] In order to prevent the reaction tube 21 outside the heat insulation assembly 26 from being at a higher temperature, Figure 2 and Figure 4 As shown, in one embodiment, the reaction mechanism 2 further includes two water cooling jackets 27 , and the two water cooling jackets 27 are both sleeved on the reaction tube 21 and arranged at both ends of the reaction tube 21 .

[0085] In this embodiment, two water cooling jackets 27 are provided, and the water cooling jackets 27 are sleeved at both ends of the reaction tube 21. The water cooling jackets 27 can water-cool both ends of the reaction tube 21. By circulating cooling water into the water cooling jackets 27, the water cooling jackets 27 and the reaction tube 21 are cooled by the cooling water, thereby preventing heat from being transferred to both ends through the reaction tube 21, and preventing the reaction tube 21 outside the insulation component 26 from being at a high temperature.

[0086] It should be understood that since carbon deposition is prone to occur at the portion where the heating component 22 heats the reaction tube 21, the cleaning component 23 and the mechanical limiting structure 25 are mainly arranged at the heated portion of the reaction tube 21 to clean the auger component 32 therein; when the auger component 32, which is located at the heated portion of the reaction tube 21, has multiple first augers 321, only the first augers 321 located at the head and tail may be cleaned, or an additional set of cleaning components 23, limiting components 24 and mechanical limiting structures 25 may be additionally arranged to clean multiple first augers 321. When additional cleaning components 23, limiting components 24 and mechanical limiting structures 25 are arranged, the specific connections of the structures may be adjusted accordingly as needed.

[0087] In the present invention, the connection may be a direct connection or an indirect connection via other components.

[0088] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
