Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and purification equipment, in particular to a spark separator and a dust removal and purification equipment. Background Art

[0002] In some dust removal projects, a large number of spark particles are generated due to the production process. For example, some welding processes generate sparks, plasma cutting processes generate a large number of metal slag splashes, and grinding wheels generate spark particle splashes during grinding. In the dust removal system of the above production processes, there is a risk of fire caused by sparks entering the interior of the dust collector. In such a dust removal system, corresponding equipment for capturing and treating spark particles in advance is required at the front end of the dust collector.

[0003] Existing spark separators mostly use principles such as cyclone, inertial collision, and water mist to eliminate the sparks generated during cutting and welding processes. Using a cyclone cylinder to eliminate sparks has a large floor area and increases the system resistance; the spark separator with inertial collision has a simple structure and occupies a small space, but the effect is not obvious; the water mist spark separator has a good effect, but it increases the secondary pollution of water, and the water-containing flue gas will affect the subsequent high-efficiency purification.

[0029] The present utility model provides a spark separator and a dust removal and purification device. Among them, the dust removal and purification device includes a spark separator. In the dust removal and purification device, the spark separator is horizontally arranged, that is, the air flow direction in the spark separator is horizontal and intersects with the gravity direction. The spark separator is used to eliminate or remove the spark particles in the spark-containing gas generated in production and manufacturing, so as to reduce the probability of risks such as fire during the dust removal and purification work on these spark-containing gases.

[0030] Figure 1 This is the structure of the spark separator in an embodiment of the present utility model. For the convenience of description, the drawings only show the structures related to the embodiments of the present utility model.

[0031] Please refer to Figure 1 and Figure 2 , the spark separator 100 includes a housing 110, a cyclone cone 120 and a plurality of cyclone vanes 130.

[0032] Please also refer to Figure 3 , the housing 110 includes a separation housing 111 in the shape of a conical tube structure and an air outlet and dust outlet housing 112 connected to one end of the separation housing 111. An air inlet 113 is formed at one end of the separation housing 111 away from the air outlet and dust outlet housing 112. An air outlet 114 and a dust outlet 115 are formed at the end of the air outlet and dust outlet housing 112 away from the separation housing 111. The dust outlet 115 is at least partially located at the lowest position of the air outlet and dust outlet housing 112.

[0033] The cyclone cone 120 is arranged in the separation housing 111 and is spaced from the inner wall of the separation housing 110. The outer diameter of the cyclone cone 120 gradually increases along the direction from the air inlet 113 to the dust outlet 115. The orthographic projection of the air outlet 114 on the large end face of the cyclone cone 120 is located within the large end face of the cyclone cone 120.

[0034] Specifically, the cyclone cone 120 is in the shape of a frustum of a cone or a shape similar to a frustum of a cone. In other embodiments, the cross-sectional shape of the cyclone cone 120 can also be a polygon, a shape similar to a circle, etc. It should be noted that the "similar" in "similar to a frustum of a cone" and "similar to a circle" means similar or close, that is, "similar to a frustum of a cone" and "similar to a circle" respectively refer to shapes similar to the frustum of a cone and shapes similar to a circle.

[0035] A plurality of cyclone vanes 130 are fixedly arranged at intervals along the circumferential direction of the cyclone cone 120. Each cyclone vane 130 is spirally arranged in the direction from the air inlet 113 to the dust outlet 115. At least part of the plurality of cyclone vanes 130 is fixedly connected to the inner wall of the separation housing 111. That is, an air flow channel extending in the spiral direction is formed between every two adjacent cyclone vanes 130, the surface of the cyclone cone 120, and the inner wall of the separation housing 111. Among them, the cyclone vanes 130 can be fixedly connected to the separation housing 111 through threaded fasteners installed on the side wall of the separation housing 111, or can be fixedly connected to the separation housing 111 by welding or other means, and can also be fixedly connected between the two through other convenient connection methods. Therefore, the cyclone cone 120 is fixed in the separation housing 111 through the cyclone vanes 130.

[0036] When the above-mentioned spark separator 100 is in use, after the airflow with sparks enters the separation housing 111 through the air inlet 113, a spiral airflow with a gradually increasing spiral radius in the direction from the air inlet 113 to the air outlet 114 is formed under the guiding action of the air flow channel. Thus, under the dual action of the specific gravity difference and the centrifugal force, the particles with sparks will be thrown out onto the inner wall of the separation housing 111, rotate along the inner wall of the separation housing 111, and finally be discharged through the dust outlet 115 under the action of their gravity. The airflow after removing the spark particles will enter the air outlet and dust housing 112 along the cyclone channel and be discharged through the air outlet 114 into the next-stage gas purification process.

[0037] Specifically, a plurality of cyclone vanes 130 are all inclined in the spiral direction relative to the diameter direction of the cyclone cone 120 to increase the centrifugal force of the airflow in the separation housing 111, which is beneficial to improving the separation effect.

[0038] Making the orthographic projection of the air outlet 114 on the large-end end face of the cyclone cone 120 be located within the end face of the large end of the cyclone cone 120 can ensure that the airflow passing through the cyclone cone 120 in the separation housing 111 will not directly rush out of the air outlet 114, reducing the probability of the airflow carrying spark particles at the air outlet 114, which is beneficial to further improving the filtering effect.

[0039] The above-mentioned spark separator 100 and the dust removal and purification equipment. There is only one cyclone cone 120 and multiple cyclone vanes 130 fixed on the cyclone cone 120 inside the entire spark separator 100. The structure is simple, which is beneficial to reducing the volume. At the same time, the above-mentioned spark separator 100 uses the cyclone cone 120 and the spiral vanes to make the air flow rotate at a high speed, and makes full use of the dual effects of the air flow speed, the relatively large specific gravity of the spark particles and the centrifugal force in the separation housing 111 to produce a separation effect, so as to separate the spark-carrying particles from the spark-carrying air flow, and the entire separation process will not cause pollution to the surrounding environment, water resources, etc. Therefore, the above-mentioned spark separator 100 has the advantages of a relatively small volume, a better separation effect and being more environmentally friendly.

[0040] In some embodiments, the connection line between the air inlet 113 and the air outlet 114 coincides with the central axis of the separation housing 111. That is, the separation housing 111 and the air outlet and dust removal housing 112 are coaxially arranged. Further, the cyclone cone 120 and the separation housing 111 are coaxially arranged. In this way, an air flow with uniform distribution and uniform flow velocity can be formed inside the outer housing 110, so that the separation effect is better and the spark separation work is more reliable.

[0041] In some embodiments, the large end of the separation housing 111 is detachably connected to one end of the air outlet and dust removal housing 112 away from the air outlet 114. Separating the outer housing 110 into two parts, namely the separation housing 111 and the air outlet and dust removal housing 112, and forming them separately is beneficial to reducing the processing difficulty of the outer housing 110. At the same time, the separation housing 111 and the air outlet and dust removal housing 112 are set to be detachably connected to facilitate the installation of the cyclone cone 120 and the cyclone vanes 130 inside the separation housing 111, making the manufacture of the spark separator 100 more simple. Of course, in other embodiments, the separation housing 111 and the air outlet and dust removal housing 112 can also be connected by means such as welding and integral molding process.

[0042] Specifically, the large end of the separation housing 111 is detachably connected to one end of the air outlet and dust removal housing 112 away from the air outlet 114 through a flat flange 116. Of course, in other embodiments, the large end of the separation housing 111 can also be detachably connected to one end of the air outlet and dust removal housing 112 away from the air outlet 114 in other ways, such as sleeving one of the separation housing 111 and the air outlet and dust removal housing 112 on the other and fastening them with threaded fasteners, or respectively setting internal and external threads at one end of the two and detachably connecting them by means of thread matching, etc.

[0043] In some embodiments, the air outlet and dust outlet housing 112 includes a dust outlet housing body 1121 and an air outlet housing body 1122 in the shape of a funnel. One end of the dust outlet housing body 1121 is connected to the large end of the air outlet housing body 1122, and the other end is connected to the large end of the separation housing 111. A dust outlet 115 is formed in the side wall of the dust outlet housing body 1121. The port at the small end of the dust outlet housing body 1121 serves as the air outlet 114.

[0044] In this way, the high-speed rotating airflow flowing out of the cyclone channel will directly contact the inner walls of the dust outlet housing body 1121 and the air outlet housing body 1122, so as to throw the unseparated spark particles in the airflow onto the inner walls of the dust outlet housing body 1121 and the air outlet housing body 1122, and slide along the inner walls to be discharged through the dust outlet 115. At the same time, the gas after removing the spark particles will change direction under the action of the inner walls of the dust outlet housing and the air outlet housing body, and thus be discharged through the air outlet 114, so as to further improve the separation effect.

[0045] Further, in some embodiments, the inner diameter of the dust outlet housing body 1121 is greater than or equal to the inner diameter of the large end of the separation housing 111. In this way, it can be ensured that the spark particles thrown onto the inner wall of the separation housing 111 under the action of centrifugal force can smoothly slide into the air outlet and dust outlet housing 112, and be discharged through the dust outlet 115 under the drive of the airflow, reducing the probability of the spark particles being stuck in the separation housing 111 and causing the spiral channel to be blocked, so as to ensure the high separation efficiency and use reliability of the spark separator.

[0046] Further, in some embodiments, one side edge of the dust outlet 115 is located on the large end face of the air outlet housing body 1122. That is, the dust outlet 115 is located at the edge part of the air outlet housing body 1122 away from the separation housing 111, so as to ensure that the spark particles falling on the inner wall of the air outlet housing body 1122 can smoothly and stably slide into the dust outlet 115, reducing the probability of the spark particles splashing and depositing in the air outlet and dust outlet housing 112, and making the separation effect and use reliability better.

[0047] In some embodiments, the end face of the small end of the cyclone cone 120 is a spherical surface 121. In this way, the airflow with sparks entering from the air inlet 113 will smoothly enter the conical surface of the cyclone cone 120 along the spherical surface 121 after contacting the spherical surface 121, reducing the probability of forming a turbulent flow after the airflow contacts the end face of the small end of the cyclone cone 120, and further improving the spark separation effect.

[0048] In some embodiments, the spark separator further includes an air outlet pipe 140. The air outlet pipe 140 is disposed through the air outlet 114. One end of the air outlet pipe 140 extends to directly above the dust outlet 115, and at least part of the dust outlet 115 is shielded in the gravity direction of the air outlet pipe 140. The other end of the air outlet 114 extends to the outside of the air outlet and dust outlet housing 112.

[0049] In this way, one end of the air outlet pipe 140 located inside the air outlet and dust removal housing 112 protrudes from the inner wall of the air outlet housing body 1122, and can at least block a part of the dust outlet 115 in the vertical direction, so as to ensure that the high-speed rotating air flow coming out of the spiral channel rebounds after contacting the inner wall of the dust removal housing body 1121 or the inner wall of the air outlet housing body 1122. As a result, the air flow removing the spark particles turns back and enters the air outlet pipe 140 for discharge, which can prevent the probability that the air flow takes away some spark particles from the air outlet 114. While further improving the separation effect, the safety risk during the dust removal and purification of the gas with sparks is further reduced.

[0050] In some embodiments, the spark separator further includes an ash discharging pipe fitting 150. One end of the ash discharging pipe fitting 150 is fixed to the bottom of the air outlet and dust removal housing 112 and is communicated with the dust outlet 115. The port of the ash discharging pipe fitting 150 at the end far from the dust outlet 115 is smaller than the dust outlet 115. That is, when the spark separator 100 is in use, the ash discharging pipe fitting 150 has a structure with a large upper end and a small lower end, so as to facilitate the spark particles in the air outlet and dust removal housing 112 to enter the ash discharging pipe fitting 150 more quickly and easily. The small end of the ash discharging pipe fitting 150 can directly collect the spark particles and send them into the ash bucket placed on the ground, or be connected to the ash bucket placed on the ground through a pipeline, which is convenient for the collection of spark particles and the cleaning of the waste residue in the ash bucket, and improves the convenience of use of the spark separator.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
