Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power generation equipment, in particular to a cyclone dust collector and a power generation system. Background Art
[0002] In modern wind power generation systems, the collector ring is one of the core components of the power generation system. Its function is to realize the energy transfer between the rotor and the stator of the power generation system. The collector ring is usually made of highly conductive materials to ensure efficient energy conversion. However, due to the friction when rotating at high speed, the carbon brushes on the collector ring will continue to wear, which not only reduces the efficiency of the power generation system, but also may cause the contact resistance between the collector ring and the carbon brush to increase, further affecting the performance of the power generation system.
[0003] Carbon powder produced by wear will accumulate in the collector ring system, especially in the relatively closed space of the collector ring chamber. At the same time, due to the compact layout between the non-drive side bearing and the encoder of the power generation system, the generation of oil mist becomes inevitable. These oil mists circulate in the closed space and are easily adsorbed with carbon powder to form conductive dirt. Over time, this dirt may cause carbon powder short circuit failure, which is a serious threat to the stable operation of the wind power generation system. At the same time, due to the conductivity of carbon powder itself, carbon powder is not allowed to flow in the air in the power system to avoid reducing the insulation performance between equipment. Therefore, it is necessary to filter and collect the carbon powder in engineering.
[0004] In existing cyclone dust collectors, the diameter of the cylinder, the size of the air inlet, and the diameter of the exhaust pipe of different sizes will affect the dust removal efficiency of the cyclone dust collector. Especially when the amount of carbon powder to be removed in the air is large and the range is wide, directly using the existing cyclone dust collector to remove the carbon powder inside the collector ring often cannot achieve a good dust removal effect. In this case, it is necessary to combine multiple smaller cyclone dust collectors to achieve better results.
[0005] However, when multiple conventional cyclone dust collectors with smaller volumes are assembled together, on the one hand, multiple devices are prone to mutual interference, not only the air volume of each device cannot be guaranteed, but also the overall dust removal efficiency of the cyclone dust collector is easily reduced. On the other hand, in order to centrally arrange the dust outlets of each cyclone dust collector as much as possible, the overall volume is larger, thereby limiting its scope of use.

DETAILED DESCRIPTION
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0025] Embodiment 1
[0026] See also Figure 1 and Figure 2 As shown, the utility model provides a cyclone dust collector, which includes: a dust removal mechanism 100, the dust removal mechanism 100 includes: a shell 110, a partition 114 is provided inside the shell 110, and in the height direction of the shell 110, the partition 114 divides the shell 110 into a suction chamber 111 and an installation chamber 112, wherein the suction chamber 111 is provided with an air suction port 1111, and the installation chamber 112 is provided with a dust inlet 1121; a plurality of cyclone dust collectors 120, a plurality of cyclone dust collectors 120 are connected to the installation chamber 112, one of the cyclone dust collectors 120 includes a barrel 123, a dust discharge port 122, an air guide pipe 121 and an air inlet pipe 124, a cavity with a wide upper part and a narrow lower part of a cone is formed inside the barrel 123, and the air inlet pipe 124 is arranged at the The cylinder 123 has an inclined side surface and is connected to the cavity. The air duct 121 is arranged at the top center of the cylinder 123 and connects the cavity with the suction chamber 111. The dust exhaust port 122 is located at the bottom of the cylinder 123 and is used to discharge foreign matter in the cavity. When the gas enters the cavity from the air inlet pipe 124, the gas rotates inside the cavity, and the impurity particles in the gas gather at the bottom of the cavity under the action of centrifugal force and gravity. The impurity particles finally fall out from the dust exhaust port 122, and the clean air is discharged from the air duct 121 at the top center. The air duct 121 is lower than the pipe mouth of the air inlet pipe 124 in the corresponding cavity, so that the dust-containing airflow can rotate along the outer wall of the air duct 121, thereby using centrifugal force to throw the dust to the inner wall of the cylinder 123, thereby achieving the purpose of separating air and dust. The suction mechanism 200 is connected to the air suction port 1111 , and is used to guide the gas to rotate in the cyclone dust collector 120 .
[0027] The cyclone dust collector described in the present invention enables the multiple cyclone dust collectors 120 inside the dust removal mechanism 100 to act simultaneously through the suction mechanism 200, and through the reasonable layout between the suction chamber 111 and the installation chamber 112 inside the shell 110, the multiple cyclone dust collectors 120 can operate independently and without interfering with each other. Based on this, compared with the existing conventional dust removal equipment, the present application has higher dust removal efficiency, more reasonable structural layout, smaller size and more stable operating effect. While collecting carbon powder, it avoids spending a lot of manpower to replace filters, reduces labor replacement costs, and has broad application prospects in wind power generation systems.
[0028] by Figure 1 The cyclone dust collector shown is a reference. In this embodiment, the shell 110 is preferably a rectangular box, and an air exhaust port 1111 and a dust inlet 1121 are provided on the right side wall at intervals, wherein the air exhaust port 1111 is used to connect the suction mechanism 200, and the dust inlet 1121 is used to absorb the air to be dust-removed. Furthermore, the suction mechanism 200 includes an air exhaust pipe 220 and a fan 210, and the shell 110 also includes a dust inlet pipe 117, and the air exhaust pipe 220 is connected between the fan 210 and the air exhaust port 1111, and one end of the dust inlet pipe 117 is connected to the dust inlet 1121, and the other end is arranged toward the area to be dust-removed. Specifically, the fan 210 in this embodiment is connected to the air exhaust port 1111 through the exhaust pipe 220, and the dust inlet pipe 117 is connected to the dust inlet port 1121. When the fan 210 is operating, the air to be dust-removed will flow through the dust inlet pipe 117, the dust inlet port 1121 and the air exhaust port 1111 in sequence, thereby realizing uninterrupted cyclic dust removal operation. Specifically, a protective shell is also provided on the outside of the fan 210 in this embodiment.
[0029] See also Figure 2 As shown, the partition 114 is horizontally connected to the interior of the shell 110 and is located in the upper and middle part of the shell 110. The periphery of the partition 114 is in contact with the inner wall of the shell 110, thereby forming two relatively closed spaces between the suction chamber 111 and the installation chamber 112. On the one hand, this structure can prevent undusted air from penetrating into the suction chamber 111 and affecting the dust removal effect. On the other hand, it also provides a location for the installation and fixation of multiple cyclone dust collectors.
[0030] In this embodiment, four small cyclone dust collectors 120 are horizontally spaced apart inside the housing 110. Figure 2The cyclone dust collector shown is a reference object. The four cyclone dust collectors 120 are arranged at intervals from left to right, and the air inlet pipes 124 corresponding to the four cyclone dust collectors 120 are all connected at the same height position. Furthermore, a fixing plate 116 is provided inside the installation cavity 112. The fixing plate 116 is arranged along the height direction of the shell 110. The fixing plate 116 is provided with connecting holes corresponding to the multiple air inlet pipes 124 one by one. The multiple air inlet pipes 124 are respectively passed through the multiple connecting holes and connected with the dust inlet port 1121. Based on this, not only can the free ends of multiple air inlet pipes 124 be connected and fixed, but also under the stopping action of the fixed plate 116, impurities such as carbon powder in the gas to be removed can all enter the corresponding cyclone dust collector through the air inlet pipe 124, thereby avoiding other problems caused by dust such as carbon powder contaminating the interior of the installation cavity 112. Specifically, the fixed plate 116 in this embodiment extends along the height direction of the shell 110, and its edges are all connected to the inner wall of the installation cavity 112.
[0031] During actual use, based on the different spacing distances between multiple cyclone dust collectors 120 and the dust inlet 1121, their suction capacities for the gas to be dusted are also different, that is, the cyclone dust collector 120 that is closest to the dust collector is more likely to absorb the gas to be dusted. Based on this, in order to ensure the efficiency of the multiple cyclone dust collectors 120, this embodiment is designed at the actual working position of the corresponding air inlet pipe 124. Specifically, the multiple cyclone dust collectors 120 in this embodiment are arranged at intervals in the installation cavity 112, and in the arrangement direction gradually away from the dust inlet 1121, the air inlet pipes 124 corresponding to the cyclone dust collectors 120 are arranged in sequence from top to bottom. Furthermore, for the cyclone dust collector 120 farthest from the dust inlet 1121, the length of its air inlet pipe 124 is relatively long, so setting it at a relatively lower position can slowly guide the flow direction of the gas, thereby making the gas flow process smoother, thereby ensuring that the gas smoothly enters the cyclone dust collector 120, and for the cyclone dust collector 120 closest to the dust inlet 1121, it can be set at a relatively upper position, when a large amount of gas flows through, its bend will stop the excessive gas, thereby achieving the effect of flow limiting and diversion. Furthermore, in this embodiment, the air inlet pipe 124 is connected to one end of the cylinder 123 and is horizontally arranged, so that the airflow entering the cavity is directly tangent to the cylinder 123. Based on this, when the gas enters the corresponding cyclone dust collector, it can flow horizontally and tangentially along the inner wall of the cyclone dust collector, thereby forming a circular rotating movement path inside it, thereby making the gas to be removed fully contact with the cylinder 123, thereby improving its dust removal efficiency.
[0032] See also Figure 2As shown, similarly, based on the different positions of the multiple cyclone dust collectors 120 from the air outlet 1111, the forces acting on them by the suction mechanism 200 are also different, that is, the cyclone dust collector 120 farthest from the air outlet 1111 sucks the least air, and is therefore prone to a phenomenon of reduced utilization efficiency due to insufficient air volume. Correspondingly, the cyclone dust collector 120 closest to the air outlet 1111 is also prone to a phenomenon of reduced dust removal efficiency due to excessive suction air velocity. In order to ensure that the air volume of the above-mentioned multiple cyclone dust collectors 120 under the action of the suction mechanism 200 can be uniform and stable, the present embodiment provides a plurality of diverter plates 130 inside the suction chamber 111, and the plurality of diverter plates 130 are respectively arranged between two adjacent air ducts 121, and the suction chamber 111 is divided into a plurality of suction channels, and the two ends of a suction channel are respectively connected to an air duct 121 and at least part of the air outlet 1111. Furthermore, multiple diverter plates 130 evenly divide the operating area of the exhaust port 1111, thereby ensuring that there is no significant difference in the gas flow rate and flow velocity in each suction channel, thereby stabilizing the air flow rate and operating efficiency inside the multiple cyclone dust collectors 120, thereby achieving the best dust removal effect and fully utilizing energy.
[0033] See also Figure 2 As shown, a dust discharge port 122 is also provided at the bottom of the cyclone dust collector; a receiving plate 115 is also provided inside the shell 110, and the receiving plate 115 is horizontally arranged to separate the shell 110 into a dust collecting chamber 113, and the dust collecting chamber 113 is arranged at the bottom of the installation chamber 112, and the dust collecting chamber 113 is connected to a plurality of the dust discharge ports 122. In this embodiment, when the corresponding cyclone dust collector 120 completes the operation, the separated carbon powder and other impurity particles can fall through the dust discharge port 122 into the dust collecting chamber 113 under the action of gravity, thereby facilitating the centralized treatment of the above impurities. Furthermore, in this embodiment, a recovery drawer is provided inside the dust collecting chamber 113, and the recovery drawer can be pulled out and connected to the shell 110. When the cyclone dust collector is finished working, the operator can discharge the waste by pulling out the drawer.
[0034] Embodiment 2
[0035] This embodiment provides another cyclone dust collector, whose general structure and principle are the same as those in the first embodiment, and will not be described in detail here. In this embodiment, a special structure of the shell 110 is used to replace the diverter plate 130 in the first embodiment, thereby achieving the same diversion effect with a simpler structure and production and processing cost. Specifically, at least part of the shell 110 at the suction chamber 111 in this embodiment is tilted, and the volume of the suction chamber 111 gradually increases in the direction of gas flow. Further, Figure 3The cyclone dust collector shown is a reference, and the air intake port 1111 is arranged on the right side of the shell 110. Therefore, in the direction from right to left, the upper surface of the shell 110 extends in a direction gradually approaching the partition 114, thereby making the volume of the suction chamber 111 in the same direction gradually decrease. Based on this structural setting, the cyclone dust collector 120 farthest from the air intake port 1111 in this embodiment can still have a large wind speed and flow rate.
[0036] Embodiment 3
[0037] This embodiment provides a power generation system, which includes at least one cyclone dust collector in the first embodiment.
[0038] In summary, the cyclone dust collector and power generation system described in the present invention enable the multiple cyclone dust collectors 120 inside the dust removal mechanism 100 to act simultaneously through the suction mechanism 200, and through the reasonable layout between the suction chamber 111 and the installation chamber 112 inside the shell 110, the multiple cyclone dust collectors 120 can operate independently and without interfering with each other. Based on this, compared with the existing conventional dust removal equipment, the present application has higher dust removal efficiency, more reasonable structural layout, smaller size and more stable operating effect. While collecting carbon powder, it avoids spending a lot of manpower to replace filters, reduces labor replacement costs, and has broad application prospects in wind power generation systems.
[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
