Description

Technical Field

[0002] Petroleum coke is a solid carbonaceous material obtained by high-temperature treatment of the heavy oil part (such as residual oil and heavy oil) produced in the process of petroleum refining. It is widely used in aluminum electrolysis, power and steel industries. During the production and processing of petroleum coke, fine particles and gaseous substances will be generated. These fumes contain a large amount of fine particulate matter (PM). These fine particles will be suspended in the air for a long time and easily enter the respiratory tract of humans and animals, endangering health and polluting the environment.

[0003] In the prior art, during the production and processing of petroleum coke, it is often necessary to purify the exhaust smoke through a purification device, such as a petroleum coke smoke purification device disclosed in China Publication No. CN221815602U. However, the above purification device still has the following technical problems during use: Since the purification device is directly connected to the exhaust port of the smoke, and the flow rate of the smoke during the exhaust process is usually different, after the smoke enters the purification device, the purification effect of the purification device for smoke with different flow rates is different, as shown below: When the smoke exhaust velocity is too high, the fine particles in the smoke will stay on the filter medium surface for too short a time, and will not have enough time to contact with the filter medium, thereby reducing the filter medium's capture efficiency for the fine particles in the smoke and reducing the purification effect; When the smoke exhaust flow rate is too low, the fine particles in the smoke will stay on the surface of the filter medium for too long, causing excessive accumulation of particles on the surface of the filter medium and forming blockage, which not only affects the subsequent purification effect, but also requires frequent cleaning of the filter medium, increasing unnecessary workload.

[0015] The present invention is provided with a high-efficiency heat-conducting mechanism. During the purification process, the rotation of the rotating rod will cause the multiple rollers on it to periodically contact and push the push plate to move, thereby driving the first piston block to reciprocate in the suction channel, thereby realizing continuous pumping in and out of the heat-conducting silicone oil, thereby allowing the heat-conducting silicone oil to circulate. Through the continuously flowing heat-conducting silicone oil, the friction heat generated by the relative rotation of the rotating inner ring and the fixed outer ring is more effectively transferred to the columnar telescopic block, thereby making the extension and shortening of the columnar telescopic block more significantly controlled by the rotating rod speed, thereby ensuring the adjustment accuracy of the purification space size and improving the purification effect of smoke and dust.

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0020] Example: Refer to Figures 1 to 5 , a petroleum coke dust purification device, comprising: A purification box 1, an air inlet pipe 11 is fixedly connected to one side wall of the purification box 1, and a plurality of filter holes 12 are provided in a rectangular array on two opposite side walls of the purification box 1; In actual use, the air intake pipe 11 is connected to the exhaust port of smoke, so that the smoke enters the purification box 1 directly through the air intake pipe 11 after being discharged, and is further filtered and purified through the multiple filter holes 12.

[0021] The regulating mechanism 2 includes two movable plates 21 which are airtightly slidably connected to the inner wall of the purification box 1. The movable plates 21 and the purification box 1 form a purification space and can be adaptively adjusted in size according to the flow rate of petroleum coke smoke. Reset springs 22 are respectively arranged between the opposite sides of the two movable plates 21 and the inner wall of the purification box 1. A flow box 23 is symmetrically arranged in the purification box 1 and between the two movable plates 21. The flow box 23 is fixedly connected to the inner wall of the purification box 1 through a first support rod. The upper and lower ends of the flow box 23 are fixedly connected with columnar telescopic blocks 24, which are made of shape memory alloy. One end of the columnar telescopic block 24 away from the flow box 23 is fixedly connected to the movable plates 21 at the corresponding position. A rotating rod 25 which is controlled by the flow rate during smoke transportation is arranged inside the purification box 1. The friction heat generating mechanism 4 is disposed between the rotating rod 25 and the columnar telescopic block 24 , and is used to adjust the temperature and deformation degree of the columnar telescopic block 24 according to the rotation speed change of the rotating rod 25 .

[0022] Specifically, the shape memory alloy used in the columnar telescopic block 24 is a copper-based multi-stage shape memory alloy, which is a special type of shape memory alloy that has multiple reversible shape memory effects, that is, during the temperature change process, the alloy can undergo multiple stages of phase change, thereby achieving multiple shape recovery.

[0023] Specifically, an annular telescopic plate 3 is sleeved on the circumference of the columnar telescopic block 24, and the annular telescopic plate 3 is fixedly connected to the flow box 23. The annular telescopic plate 3 is used to limit the deformation range of the columnar telescopic block 24, so that the columnar telescopic block 24 can only be telescoped along the axial direction when the temperature changes.

[0024] The friction heat generating mechanism 4 includes a U-shaped plate 41 fixedly connected to the inner wall of the purification box 1, and the rotating rod 25 passes through and is rotatably connected to the U-shaped plate 41. The part of the rotating rod 25 extending into the air intake pipe 11 is provided with axial flow fan blades 42, and the part of the rotating rod 25 extending into the purification box 1 is fixedly connected with a rotating inner ring 43. The circumferential side of the rotating inner ring 43 is provided with a fixed outer ring 44 in contact with the rotating inner ring 43. The rotating inner ring 43 is made of high carbon steel, and the fixed outer ring 44 is made of metal aluminum. Heat dissipation holes are provided at the contact position between the rotating inner ring 43 and the fixed outer ring 44. A high-efficiency heat conduction mechanism 5 is also provided between the fixed outer ring 44 and the flow box 23, which is used to efficiently transfer the heat generated when the rotating inner ring 43 rotates relative to the fixed outer ring 44 to the columnar telescopic block 24, so as to ensure that the columnar telescopic block 24 can be controlled by the rotation speed of the rotating rod 25.

[0025] Specifically, the heat dissipation holes (not marked in the figure) opened here can dissipate heat between the rotating inner ring 43 and the fixed outer ring 44. The heat received by the elastic telescopic block 24 is equal to the friction heat generated between the rotating inner ring 43 and the fixed outer ring 44 minus the heat released, thereby avoiding heat accumulation caused by continuous frictional heat generation and making it impossible to control the temperature of the elastic telescopic block 24 due to the rotation speed of the rotating rod 25.

[0026] In view of the problem that after smoke enters the purification device in the prior art, the purification effect of the purification device for smoke at different flow rates is different. When the flow rate is too high when the smoke is discharged, there is not enough time for the smoke to contact the filter medium, thereby reducing the capture efficiency of the filter medium for fine particles in the smoke. When the flow rate is too low when the smoke is discharged, excessive accumulation of particles on the surface of the filter medium causes blockage. In the present invention, by setting an adjustment mechanism 2, when the smoke is transported to the inside of the purification box 1 through the air inlet pipe 11 for purification, the impact force generated by the smoke transporting airflow can drive the axial flow fan blades 42 to rotate, and further drive the rotating rod 25 to rotate: It is to be noted that, since the shape memory alloy used in the columnar telescopic block 24 is a copper-based multi-stage shape memory alloy, it can perform multiple reversible shape memory effects when the temperature changes, so that when the rotation speed of the rotating rod 25 is within different ranges, the columnar telescopic block 24 will be extended or shortened to different degrees; When the exhaust velocity of smoke and dust is too high, the velocity of smoke and dust when it enters the purification box 1 is high, so that the rotation speed of the rotating rod 25 is faster, and the friction force is further overcome to drive the relative rotation speed between the rotating inner ring 43 and the fixed outer ring 44 to be faster, so that during the rotation of the rotating inner ring 43, the friction between the rotating inner ring 43 and the fixed outer ring 44 generates a large amount of heat (it should be noted that the heat dissipation efficiency will change accordingly due to the heat generated by friction, but the change is negligible), and the heating effect of the annular heat conductive sheet is greater, so that the columnar expansion and contraction at the upper and lower ends of the flow box 23 The temperature of the block 24 is relatively high, so that the columnar telescopic block 24 expands and stretches, and when the degree of temperature increase of the columnar telescopic block 24 is within different ranges, the length of extension of the columnar telescopic block 24 is different, so that the two movable plates 21 can overcome the elastic force of the return spring 22 and move away from each other, so that the purification space in the purification box 1 is increased, the time for smoke to pass through the purification box 1 is prolonged, the residence time of smoke in the purification box 1 is prolonged, and the contact time of smoke with the filter hole 12 is longer, thereby improving the capture efficiency of particulate matter and improving the purification effect; When the smoke exhaust flow rate is too low, the flow rate when it enters the purification box 1 is low, which makes the rotation speed of the rotating rod 25 slower, driving the relative rotation speed between the rotating inner ring 43 and the fixed outer ring 44 slower, and the heat generated by friction is smaller, so that the temperature of the columnar telescopic block 24 is relatively low, causing the columnar telescopic block 24 to shrink and shorten, and when the degree of temperature reduction of the columnar telescopic block 24 is within different ranges, the shortening length of the columnar telescopic block 24 is different, so that the two movable plates 21 are able to approach each other under the elastic force of the return spring 22, thereby reducing the purification space in the purification box 1, shortening the time for smoke to pass through the purification box 1, shortening the residence time of smoke in the purification box 1, and shortening the contact time between smoke and the filter hole 12, avoiding excessive accumulation of particles on the surface of the filter medium, preventing blockage, and ensuring the purification effect.

[0027] The efficient heat conduction mechanism 5 includes an annular flow guide box 51 fixedly installed inside the purification box 1, the annular flow guide box 51 is fixedly connected to the inner wall of the purification box 1 away from the air inlet pipe 11 through a second support rod, the fixed outer ring 44 is fixedly connected to the inner wall of the annular flow guide box 51, and the fixed outer ring 44 extends to the inside of the annular flow guide box 51, both sides of the annular flow guide box 51 are connected with a liquid inlet pipe 52 and a liquid discharge pipe 53, the liquid inlet pipe 52 and the liquid discharge pipe 53 are connected with the inside of the flow box 23 at the corresponding position, the liquid inlet pipe 52 is fixedly connected with a suction channel 54, and the suction channel 54 is airtightly slidably connected with a first piston block 55, the first A first spring 56 is provided between the piston block 55 and the inner wall of the suction channel 54, and a push rod 57 is fixedly connected to one end of the first piston block 55 away from the liquid inlet pipe 52, one end of the push rod 57 extends to the outside of the suction channel 54 and is fixedly connected to a push plate 58, a plurality of L-shaped rods 59 distributed in a circular array are fixedly connected to the rotating rod 25, a roller 510 is rotatably connected to one side of the L-shaped rod 59 close to the push plate 58, and the roller 510 rolls in contact with the push plate 58, and one-way valves are provided at positions on both sides of the suction channel 54 in the liquid inlet pipe 52, and the annular guide box 51, the liquid inlet pipe 52, the flow box 23 and the discharge pipe 53 are filled with thermal conductive silicone oil.

[0028] Specifically, thermally conductive silicone oil has good thermal conductivity and can effectively conduct heat.

[0029] Specifically, the one-way valve is set so that when the first piston block 55 moves in the suction channel 54, the thermal conductive silicone oil in the annular guide box 51 can only be pumped into the suction channel 54, and the thermal conductive silicone oil in the suction channel 54 can only be pumped out into the flow box 23, thereby avoiding the backflow of the circulating flow of the thermal conductive silicone oil.

[0030] Specifically, the upper and lower ends of the flow box 23 are fixedly connected with an annular heat conductive plate in contact with the columnar telescopic block 24, and the annular heat conductive plate extends to the interior of the flow box 23 to ensure the heating effect of the thermal silicone oil on the annular heat conductive plate. The rotating rod 25 and the annular flow guide box 51 except the rotating inner ring 43 and the fixed outer ring 44, the other areas of the flow box 23 except the annular heat conductive plate, the liquid inlet pipe 52 and the liquid discharge pipe 53 are all made of polyurethane foam material with good thermal insulation performance, thereby ensuring that the heat generated by friction can be well transferred to the annular heat conductive plate through the thermal silicone oil, and further transfer the heat to the columnar telescopic block 24, avoiding heat loss during the conduction process.

[0031] Specifically, a first partition 6 is fixedly connected to a position between the liquid inlet pipe 52 and the liquid discharge pipe 53 in the flow box 23, so that the thermal conductive silicone oil can first enter the flow box 23 from the liquid inlet pipe 52 when flowing, and be discharged from the liquid discharge pipe 53 on the other side of the first partition 6 to the inside of the annular guide box 51 when it flows almost one circle in the flow box 23, thereby ensuring that the thermal conductive silicone oil can fully transfer heat to the columnar telescopic blocks 24 fixed at the upper and lower ends of the flow box 23 during the flow process, thereby ensuring the heating effect of the annular heat conductive plate on the columnar telescopic blocks 24.

[0032] Specifically, the discharge pipe 53 is fixedly connected with a buffer channel 7, and a second piston block 71 is airtightly slidably connected in the buffer channel 7. A second spring 72 is provided between the second piston block 71 and the inner wall of the buffer channel 7. When the first piston block 55 moves in the inlet pipe 52 and the thermal conductive silicone oil in the annular guide box 51 is pumped into the inlet pipe 52, the elastic force of the second spring 72 will cause the second piston block 71 to move in the buffer channel 7. When the first piston block 55 is reset in the suction channel 54 under the elastic force of the first spring 56, since the elastic coefficient of the first spring 56 is greater than the elastic coefficient of the second spring 72, the hydraulic pressure of the thermal conductive silicone oil will overcome the elastic force of the second spring 72, so that the second piston block 71 is reset in the buffer channel 7. In the process of continuous suction and flow of the thermal conductive silicone oil, a buffering effect is exerted on the thermal conductive silicone oil, so that the thermal conductive silicone oil is always in a filled state, thereby ensuring its heat conduction effect.

[0033] It is worth mentioning that the present invention provides a high-efficiency heat-conducting mechanism 5. During the purification process, the friction heat generated by the relative rotation between the rotating inner ring 43 and the fixed outer ring 44 will be directly transferred to the heat-conducting silicone oil in the annular guide box 51. The heat-conducting silicone oil further transfers the heat to the columnar telescopic block 24 through the annular heat-conducting sheet. During this process, the rotation of the rotating rod 25 will cause the multiple rollers 510 on it to periodically contact and push the push plate 58 to move, further causing the first piston block 55 to move in the suction channel 54, and when the roller 510 is not in contact with the push plate 58, the first piston block 55 is elastically moved in the first spring 56. The piston 55 is reset under the action of force, and the reciprocating movement of the first piston block 55 in the suction channel 54 realizes the continuous pumping in and out of the thermal conductive silicone oil, so that the thermal conductive silicone oil can circulate in the annular guide box 51, the liquid inlet pipe 52, the flow box 23, and the liquid discharge pipe 53. Through the continuous flow of the thermal conductive silicone oil, the friction heat generated by the relative rotation of the rotating inner ring 43 and the fixed outer ring 44 is more effectively transferred to the columnar telescopic block 24, so that the extension and shortening of the columnar telescopic block 24 is more obviously controlled by the rotation speed of the rotating rod 25, thereby ensuring the adjustment accuracy of the purification space size and improving the purification effect of smoke and dust.

[0034] A speed sensor 8 is provided on the U-shaped plate 41, and the speed sensor 8 includes a Hall effect sensor and an arc magnet fixedly connected to the rotating rod 25. An annular heating plate, an annular cooling plate and a temperature sensor 81 are fixedly connected to the interior of the annular guide box 51. A microcontroller 82 is fixedly connected to the outer wall of the annular guide box 51. A feedback unit is provided inside the microcontroller 82. The speed sensor 8, the temperature sensor 81 and the annular heating plate are all electrically connected to the microcontroller 82.

[0035] It should also be noted that when the rotating rod 25 rotates, the arc-shaped magnet thereon will drive the magnetic field to change. When the magnetic field passes through the Hall effect sensor, the electron flow inside the Hall effect sensor will be deflected, generating a voltage signal related to the magnetic field strength. During the purification process, the speed sensor 8 will detect the speed data of the rotating rod 25 and the temperature sensor 81 will detect the temperature data of the thermal conductive silicone oil to the feedback unit through an electrical signal. The feedback unit detects whether the speed of the rotating rod 25 is the same as the corresponding temperature of the thermal conductive silicone oil by comparing the speed data and the temperature data. When the temperature of the thermal conductive silicone oil is lower than the temperature corresponding to the speed of the rotating rod 25, the annular heating plate heats the thermal conductive silicone oil. When the temperature of the thermal conductive silicone oil is higher than the temperature corresponding to the speed of the rotating rod 25, the annular cooling plate cools the thermal conductive silicone oil until the temperature of the thermal conductive silicone oil is the same as the temperature corresponding to the speed of the rotating rod 25, thereby realizing accurate control of the temperature of the thermal conductive silicone oil by the speed of the rotating rod 25, thereby making the control of the size of the purification space in the purification box 1 more accurate.

[0036] The present invention can be explained by the following operation mode: The air inlet pipe 11 is connected to the exhaust port of smoke, so that the smoke can directly enter the purification box 1 through the air inlet pipe 11 after being discharged, and further be filtered and purified through the multiple filter holes 12; When the smoke is transported to the inside of the purification box 1 through the air intake pipe 11 for purification, the impact force generated by the airflow during the smoke transportation can drive the axial flow blades 42 to rotate, and further drive the rotating rod 25 to rotate: when the flow rate of smoke is too high when it is discharged, the heat generated by the friction between the rotating inner ring 43 and the fixed outer ring 44 is relatively large. Since the columnar telescopic block 24 is made of shape memory alloy, it can expand and stretch, so that the purification space in the purification box 1 is increased, and the contact time of smoke and filter holes 12 is longer, thereby improving the capture efficiency of particulate matter; and when the flow rate of smoke is too low when it is discharged, the heat generated by the friction between the rotating inner ring 43 and the fixed outer ring 44 is relatively small, so that the purification space in the purification box 1 is reduced, and the contact time of smoke and filter holes 12 is shorter, thereby avoiding excessive accumulation of particles on the surface of the filter medium; The rotation of the rotating rod 25 causes the multiple rollers 510 thereon to periodically contact and push the push plate 58 to move, further causing the first piston block 55 to move in the suction channel 54, so that the first piston block 55 reciprocates in the suction channel 54, realizing continuous pumping in and out of the thermal conductive silicone oil, thereby allowing the thermal conductive silicone oil to circulate in the annular guide box 51, the liquid inlet pipe 52, the flow box 23, and the liquid discharge pipe 53, and more effectively transferring the generated friction heat to the columnar telescopic block 24; When the temperature of the thermally conductive silicone oil is lower than the temperature corresponding to the rotation speed of the rotating rod 25, the annular heating plate heats the thermally conductive silicone oil. When the temperature of the thermally conductive silicone oil is higher than the temperature corresponding to the rotation speed of the rotating rod 25, the annular cooling plate cools the thermally conductive silicone oil until the temperature of the thermally conductive silicone oil is the same as the temperature corresponding to the rotation speed of the rotating rod 25, thereby improving the control accuracy of the rotation speed of the rotating rod 25 on the temperature of the thermally conductive silicone oil.
