Description

Dynamic interception purifier

Technical Field

The invention relates to the technical field of air purification, in particular to a dynamic intercepting purifier.

Background

The dynamic interception purifier can remove particulate matters in the exhaust gas. Chinese patent application publication No. CN100591405C discloses a "dynamic physical dynamic interception purifier, a manufacturing method thereof, and a special fixture", wherein spokes of the dynamic physical dynamic interception purifier adopt circular spokes for removing particulate matters in flowing air; however, when the circular spokes rotate along with the central disc, the circular spokes can impact particles at a high speed, and because the surfaces of the circular spokes are convex surfaces, the particles can rebound and disperse around after the convex surfaces impact the particles, only a part of the particles can be attached to the steel wire, the particles which are not attached can form a large amount of smoke, and particularly when the UV paint mist is treated, the smoke quantity is very large; because the adhesiveness of the solid particles is smaller than that of the liquid particles, the solid particles can not be removed basically when the particles to be removed are solid particles rather than liquid particles. This problem can also be present with square spokes or other polygonal spokes.

Disclosure of Invention

In view of this, in order to solve one of the technical problems in the related art to a certain extent, it is necessary to provide a dynamic intercepting purifier, which reduces the generation of finer particles, avoids the generation of a large amount of smoke, and greatly improves the intercepting effect.

The invention provides a dynamic intercepting purifier, which comprises a central seat and spokes with inner ends connected with the central seat, wherein the spokes can rotate around a rotation axis along with the central seat, and the spokes are provided with grooves, and the openings of the grooves face to the same direction as the rotation direction of the spokes.

Further, the groove has a front inner wall surface and a rear inner wall surface, the front inner wall surface and/or the rear inner wall surface being inclined with respect to the rotation surface of the spoke from an end portion close to the opening toward a groove bottom direction of the groove, wherein an upstream end in a flow direction of particulate matter is a front and a downstream end is a rear.

Further, the front inner wall surface and the rear inner wall surface are inclined in opposite directions with respect to the rotation surface of the spoke and the distance between the front inner wall surface and the rear inner wall surface gradually decreases in a direction away from the opening.

Further, a distance between an end of the front inner wall surface close to the opening and a groove bottom of the groove is L1, and a distance between an end of the rear inner wall surface close to the opening and a groove bottom of the groove is L2, wherein L2 is greater than or equal to L1.

Further, the groove is a substantially V-shaped groove or a U-shaped groove.

Further, the spoke comprises a first part and a second part, the first part and the second part are connected to form the groove, and the ends of the first part and the second part close to the opening are pointed.

Furthermore, the spokes are provided with ventilation openings approximately at the positions of the grooves.

Further, the slots extend along the length of the spoke towards the outer end of the spoke.

Further, the dynamic intercepting purifier further comprises an outer ring, the outer end of the spoke is connected to the outer ring, and a through hole is formed in the corresponding position of the groove of the outer ring, so that the particulate matters collected in the groove can be discharged out of the outer ring from the through hole under the action of centrifugal force along the groove.

Further, the multi-layer spoke layer comprises a plurality of spoke layers, and adjacent spoke layers are fixed through fixing rings.

According to the scheme, the spoke is provided with the grooves, the opening directions of the grooves are approximately the same as the rotating direction of the spoke, and in the high-speed rotating process of the spoke, particulate matters can enter the grooves from the openings and impact the inner wall surfaces of the grooves, so that even if the particulate matters are rebounded and dispersed, the particulate matters can still be collected by the grooves, and therefore a large amount of smoke of finer particulate matters can be avoided, and the intercepting effect is improved.

Referring to fig. 1, the embodiment of the present invention provides a dynamic intercepting purifier 100, which may include a central seat 10 and spokes 20, wherein the number of the spokes 20 may include a plurality of spokes, preferably 200 spokes, and it is understood by those skilled in the art that the number of the spokes 20 may be selected according to the comprehensive purifying effect (probability of contacting with the particulate matter 300) and the wind resistance influence. In order to avoid that the spokes 20 have a large wind resistance during rotation, the width of the spokes 20 is preferably not too large. The spokes 20 are connected to the central seat 10 at the inner ends thereof, the spokes 20 may extend radially outward, and a plurality of the spokes 20 are radially distributed. Referring to fig. 2, in order to improve the fixing effect of the spokes 20, the dynamic intercepting purifier 100 may further include an outer ring 30, and the outer ends of the spokes 20 are connected to the outer ring 30.

It can be understood that, referring to fig. 3, the dynamic intercepting purifier 100 provided by the present invention may further include a plurality of spoke layers 201, for example, two spoke layers 201, wherein the spokes 20 of the innermost spoke layer 201 are fixed on the central seat 10, the adjacent spoke layers 201 are fixed by the fixing ring 31, the spoke layers 201 of the outer layers include a larger number of spokes 20, and the spoke layers 201 of the inner layers include a smaller number of spokes 20, so that the dynamic intercepting purifier 100 may be provided with different spoke 20 densities at different radius areas, and it is ensured that the spoke 20 gaps at different radius areas are approximately the same, so that the purifying effect of the particulate matters 300 at different radius areas is substantially the same.

The center base 10 may be connected with a rotation driving motor 200, the rotation driving motor 200 drives the center base 10 to rotate around a rotation axis O, and since the inner ends of the spokes 20 are connected to the center base 10, the spokes 20 can rotate around the rotation axis O together with the center base 10, it is understood that the rotation speed can be adjusted according to the concentration of the particulate matters 300 in the air or the purification effect, and is not limited herein.

Referring to fig. 5-9, the spokes 20 have slots 210 with the openings 220 of the slots 210 facing in substantially the same direction of rotation M of the spokes 20, it being understood that substantially the same may be the case if the openings 220 are facing at an angle to the direction of rotation M, provided that the particulate matter 300 is able to pass from the openings 220 into the slots 210 during rotation. Taking the example of clockwise rotation in the upstream direction, when the spoke 20 rotates clockwise at a high speed around the rotation axis O along with the center seat 10, the rotation direction M is M, the rotation speed is V1, the gas with entrained particulate matters 300 flows to the dynamic interceptor purifier 100 at a speed V2, the upstream end of the gas flow direction N is forward, the downstream end is backward, and the speed of V1 is much higher than V2, so that the flow rate of the particulate matters 300 after reaching the dynamic interceptor purifier 100 is negligible with respect to the rotation speed of the spoke 20, the speed of the particulate matters 300 after reaching the dynamic interceptor purifier 100 is relatively negligible and is in a stationary state, the particulate matters 300 will quickly enter the groove 210 from the opening 220 of the groove 210 and impinge on the inner wall surface of the groove 210, and after the particulate matters 300 are impinged, the spoke 20 rotates at a very high speed, so that the dispersed particulate matters 300 can be quickly accommodated in the groove 210, avoiding the generation of a large amount of fine particles.

The spoke 20 can be made of a first part 21 and a second part 22, the first part 21 and the second part 22 are connected to form the slot 210, the ends 221 of the first part 21 and the second part 22 near the opening 220 are pointed, the thickness of the pointed ends 221 is very small, preferably not more than 0.3mm, furthermore, the spoke 20 can be approximately V-shaped (as shown in FIG. 5, FIG. 6 and FIG. 10) or U-shaped (as shown in FIG. 7 and FIG. 8), and the width of the spoke 20 can be reduced.

Wherein the first portion 21 and the second portion 22 are thin and narrow steel plates forged from iron wire, and the ends 221 of the first portion 21 and the second portion 22 can be welded together so that the gap between the first portion 21 and the second portion 22 forms the groove 210.

The slot 210 (fig. 5, 6, 10) may be generally V-shaped or U-shaped (fig. 7 and 8), although the shape of the slot 210 may be substantially the same as or different from the shape of the spoke 20. The groove 210 has a front inner wall surface 211 and a rear inner wall surface 212, the front inner wall surface 211 and the rear inner wall surface 212 can be main collision surfaces, and the front inner wall surface 211 and the rear inner wall surface 212 may be flat surfaces or concave arc surfaces. Preferably, the front inner wall surface 211 is inclined from the end 221 close to the opening 220 toward the groove bottom of the groove 210 with respect to the rotation plane Q of the spoke 20 by an inclination angle θ 1; the rear inner wall surface 212 is inclined from the end 221 close to the opening 220 toward the groove bottom of the groove 210 by an angle θ 2 relative to the rotation plane Q of the spoke 20, wherein the values of θ 1 and θ 2 may be different, preferably the same; the inclined front inner wall surface 211 and rear inner wall surface 212 facilitate soft collision of the particulate matter 300, the probability of the particulate matter 300 being dispersed is smaller, and the orientation after dispersion is more uniform, facilitating collection of the dispersed particulate matter 300 by the groove 210. Preferably, the included angle between front inner wall surface 211 and rear inner wall surface 212 is not greater than 90 °, which facilitates collection of particulate matter.

Specifically, the inclination directions of front inner wall surface 211 and rear inner wall surface 212 are opposite, and the distance between front inner wall surface 211 and rear inner wall surface 212 gradually decreases in the direction away from opening 220, and preferably, the values of θ 1 and θ 2 are the same, that is, front inner wall surface 211 and rear inner wall surface 212 are symmetrical. Optionally, as shown in fig. 9, the spoke 20 is provided with a ventilation opening 213 substantially at the bottom of the slot 210, when the ventilation opening 213 is provided, during the rotation of the spoke 20, the airflow can enter the slot 210 more conveniently, thereby facilitating the contact of the particulate matter with the front inner wall surface 211 and the rear inner wall surface 212, and the ventilation opening 213 can extend along the length direction of the slot along with the slot, so that the spoke 20 is substantially in a figure eight shape. In the molding process, the vent 213 may be opened after the first portion 21 and the second portion 22 are welded, or the vent 213 may be directly formed by spacing one side of the first portion 21 and one side of the second portion 22 apart from each other.

As shown in fig. 10, a distance between an end 221 of front inner wall surface 211 adjacent to opening 220 and a bottom of groove 210 is L1, and a distance between an end 221 of rear inner wall surface 212 adjacent to opening 220 and a bottom of groove 210 is L2, where L2 is greater than or equal to L1. As shown in fig. 10, when L2 is greater than L1, such that end 221 of rear inner wall surface 212 protrudes from end 221 of front inner wall surface 211, and the area of rear inner wall surface 212 is greater than the area of front inner wall surface 211, in the foregoing, although the flow velocity of particulate matter 300 reaching dynamic intercept purifier 100 is negligible with respect to the rotation speed of spoke 20, but still flows backward, most particulate matter 300 mainly collides with rear inner wall surface 212, and a small portion of particulate matter 300 collides with front inner wall surface 211, because the area of rear inner wall surface 212 is slightly large, particulate matter 300 is in contact with it, so as to improve the cleaning effect of particulate matter 300, when the inclination direction of front inner wall surface 211 and rear inner wall surface 212 is opposite, and the distance between front inner wall surface 211 and rear inner wall surface 212 gradually decreases toward the direction away from opening 220, during rotation, the front inner wall surface 211 generates a flabellum effect to make the airflow flow to the downstream end, so that the speed of the particulate matters 300 passing through the purifier 100 is increased, while the rear inner wall surface 211 generates a flabellum effect to make the airflow flow to the upstream section, so that the speed of the particulate matters 300 passing through the purifier 100 is reduced, if L2 is equal to L1, the speed is substantially offset, and if L2 is greater than L1, the rotating spokes 20 provide a power for the particulate matters 300 to flow in a reverse direction (i.e., to move to the upstream end).

Preferably, as shown in fig. 11, the slots 210 may extend along the length of the spokes 20 toward the outer ends of the spokes 20 and may extend to the outer ends 230 of the spokes 20, so that the slots 210 are elongated along the length of the spokes 20, and when the particles 300 are deposited on the inner surface of the slots 210, the spokes 20 generate centrifugal force F during high-speed rotation, and the particles 300 flow along the slots 210 toward the outer ends and are discharged out of the slots 210, thereby preventing the particles 300 from accumulating in the slots 210. Correspondingly, the outer ring 30 is provided with a through hole 310 at a corresponding position of the groove 210, and when the particulate matters 300 flow along the groove 210 to the outer end, the particulate matters 300 can be discharged out of the outer ring 30 through the through hole 310, so that the particulate matters 300 can be conveniently collected in the outer ring 30.
