Abstract
The invention discloses a dust re-scattering prevention module of a filter dust collector, which is characterized in that the dust re-scattering prevention module is arranged at the upper end part of a shell of the filter dust collector, so that the inflowing air generates down-flow around a plurality of filters in the shell. Further, the present invention discloses a dust collecting device, comprising: a housing; a plurality of filter bags extending vertically in the housing; and a dust re-scattering prevention module of the filter dust collector, which is arranged at the upper end part of the shell and enables the inflowing air to generate a downward air flow around the plurality of filter bags.
Description
Technical Field
The present invention relates to a dust re-scattering prevention module and a dust collection device including the same, and more particularly, to a dust re-scattering prevention module for a filter dust collector, which prevents dust accumulated in a lower portion of a dust collection device from being re-scattered by generating a down-flow in the dust collection device by air flowing into the dust collection device, and a dust collection device using the same.
Background
In order to collect particulate pollutants such as discharged dust, a filter dust collector is generally used in various industrial facilities.
This filter dust collector is provided with a bag filter (bag filter) and can efficiently filter fine dust particles and the like. When the filter is used, although there is an advantage that the dust collection efficiency can be improved by increasing the particle capturing rate, if the dust layer is excessively formed on the filter surface, pressure loss occurs, and therefore, it is necessary to periodically remove dust.
However, in the conventional dust filter collecting device, there is a problem that dust is again scattered when the dust layer on the filter surface is removed in the dust removing step or when air is introduced through the inlet port at the lower portion, and the dust collecting efficiency of the device is lowered.
More specifically, according to the structure of the conventional dust filter collector (see fig. 1), air containing dust can flow in through an inlet port at the lower part of the dust filter collector, and flow out through an outlet port at the upper part of the dust filter collector. In this configuration, when the air flows, the dust accumulated in the lower portion of the apparatus may be re-scattered, and the dust detached in the dust-removing step may be re-scattered without being deposited in the lower portion of the apparatus, thereby reducing the efficiency of the filter.
As one of attempts to solve these problems, an off-line dust removal method has been introduced in the prior art.
In the off-line dust removing method, the operation of the bag filter dust collecting device is stopped during the dust removing operation, and the dust removing efficiency is very high because of no upward air flow, but the operation of the equipment cannot be stopped every time the dust is removed because of industrial characteristics. However, in this case, since the above-described device is additionally provided, there is a problem that the overall installation cost of the bag filter dust collector increases by about 30% or more.
Korean granted patent No. 10-0764753, "center-filtering type bag filter dust collector (hereinafter, referred to as patent document 1)", discloses a method of removing dust by moving dust generated in a bag filter chamber to a cyclone chamber.
More specifically, patent document 1 discloses a structure in which air from which dust is first removed in a cyclone is smoothly moved to an upper bag filter, and dust falling from a pocket of the bag filter is smoothly lowered by the cyclone, thereby preventing dust and foreign matter from being accumulated in an upper bag filter chamber of a venturi tube.
However, according to the structure of patent document 1, the installation of an additional venturi in the center of the dust collecting device may increase the cost of the device, block the flow of the air flowing in, and reduce the installation efficiency.
Korean patent No. 10-1168680 entitled "dust collector dust scattering prevention device (hereinafter referred to as patent document 2)" discloses a structure that can confirm the dust collection state of a dust collector in real time and prevent dust from scattering due to a dust collection error.
In view of the above, patent document 2 discloses that a lifting body that lifts and lowers according to the pressure of the suction air sucked into the dust collector is provided, a marker body that lifts and lowers in conjunction with the lifting operation of the lifting body is provided, and the worker confirms the lifting and lowering of the marker body to confirm the dust collection state of the dust collector in real time.
That is, patent document 2 does not disclose a solution for fundamentally preventing the re-scattering of the dust generated by the updraft, and only discloses a post-treatment method when the re-scattering occurs.
Korean laid-open patent publication No. 2003-0089791, "bag filter dust collecting apparatus for preventing re-scattering and re-attachment (hereinafter, referred to as patent document 3)", discloses a structure for reducing the dust load of a bag filter by preventing dust clusters from re-scattering and re-attachment to the bag filter when dust collected by the bag filter is removed.
Specifically, patent document 3 discloses a conventional bag filter dust collecting device in which a funnel-shaped dust collecting plate is provided below a bag filter to collect dust removed, and the dust collecting plate and a dust storage tank are connected by a discharge pipe structure so that the dust collected on the collecting plate moves to the dust storage tank.
However, patent document 3 does not disclose a solution for fundamentally preventing re-scattering, and only discloses a method for reducing the amount of re-scattered dust by discharging the dust after dust removal to the outside.

Detailed Description
The dust re-scattering preventing module of the filter dust collector and the dust collecting device using the same according to the present invention may have various modified embodiments. Hereinafter, several of the embodiments will be specifically described in this specification with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments, and all modifications, equivalents, and alternatives within the technical spirit and scope of the present invention are to be understood as included.
In the following, the same or similar structures are given the same or similar reference numerals throughout the specification, and the same description will be replaced by the description given for the first time, even in different embodiments. The singular expressions include the plural expressions unless the context clearly indicates otherwise.
The "module" or "section" of the constituent elements used in the following description is for convenience of description, and does not have a mutually different meaning or function.
Fig. 2 is a schematic view of the dust collecting apparatus 100 equipped with a dust re-scattering prevention module 200 of a filter dust collector according to an embodiment of the present invention.
Since a large amount of dust needs to be disposed at once, a large number of filters need to be provided inside a large-scale dust collecting apparatus, and in order to effectively operate such a dust collecting apparatus, a filter bundle formed by bundling a plurality of filters can be arranged adjacently. Hereinafter, for convenience of description, a form in which a plurality of filters are bundled in a predetermined unit is collectively referred to as a "filter bundle" in the present specification.
According to an embodiment of the present invention, the dust collecting apparatus 100 includes a plurality of filter bundles disposed inside the housing 101. For example, as shown in FIG. 2, first filter bundle 130 and second filter bundle 140 may be adjacently disposed.
The upper side of the housing 101 may be configured with a first cover for covering the first filter bundle 130 and a second cover for covering the second filter bundle 140. When a user performs work such as replacement, repair, and cleaning of the filters, the user only needs to open the covers of the filters and perform work in units of filter bundles without stopping the operation of all the filters.
Referring to fig. 2, a filter dust collector dust re-scattering prevention module 200 may be provided at an upper end of the housing 101.
The dust re-scattering prevention module 200 is disposed at the upper end of the housing 101 so as to surround the filter.
As shown, the dust re-scattering prevention module 200 forms a gas collecting channel 102 on one side surface for air to flow in. The downward air current jetting surface 231, the downward air current collecting protrusion 241, and the like may be formed at the lower portion of the dust re-scattering prevention module 200.
Fig. 3 is an enlarged schematic view of the filter dust collector dust re-scattering prevention module 200 shown in fig. 2, and fig. 4 is a sectional view of the filter dust collector dust re-scattering prevention module 200 as viewed through line IV-IV of fig. 3.
Referring to fig. 3 and 4, a gas collecting channel 102 for allowing air to flow in is formed on the left side surface of the dust filter re-scattering prevention module 200.
The air flowing in through the air collection hood 102 can move along the filter protection wall 221 surrounding the filter to the interior of the device. Since the air pressure is strong when the air flows, the filter can be prevented from being damaged by the protection of the filter protection wall 211.
Then, a part of the air colliding with the curved filter protection wall 221 moves to the protection wall 221 on the rear side along the curved surface, and a part of the air is reflected to the protection walls 221 on both sides.
The air thus introduced is scattered all around and flows along the periphery of each filter.
The lower portion of the dust re-scattering prevention module 200 forms an air flow ejection surface 231. The central portion of the air ejection surface 231 forms an air ejection hole.
The air jet holes are formed at the same distance from the adjacent two filters.
According to an embodiment of the present invention, the gas flow injection surface 231 is inclined downward as it is farther from the filter, and injection holes may be formed at the lowermost end portion of the inclined injection surface 231.
Also, according to another embodiment of the present invention, an end portion (injection hole boundary) of the injection surface 231 may be formed with a protrusion protruding upward. Due to the protrusion of the air before the jet holes, larger dust can be filtered before the downdraft is formed.
As shown, the boundaries of the plurality of filter bundles may form descending air flow concentrating protrusions 241.
As described above, a plurality of filter bundles can be operated independently of each other in a large-scale dust collecting apparatus. When a plurality of filter bundles operate independently of each other, dust from one filter bundle may fly and flow into another filter, and according to the present embodiment, a strong down flow is generated at the boundary of the filter bundle, so that dust flying from one filter bundle can be prevented from flowing into the other filter bundle.
The downward air flow concentrating protrusion 241 may be formed in a protrusion shape protruding downward from an end (injection hole boundary) of the injection surface 231. The descending-air-flow concentrating protrusion 241 prevents the filter from being damaged due to collision with the filter.
According to another embodiment of the present invention, the downward air flow concentrating protrusion 241 may have protrusions spaced apart from each other with a predetermined gap therebetween. The protrusion may be arranged in a V-shape or U-shape with the lower end portion open. This makes it possible to generate a region of stronger downdraft at the filter bundle boundary at predetermined intervals.
Fig. 5 is a sectional view of a dust re-scattering prevention module 200 of a filter dust collector according to another embodiment of the present invention.
Referring to fig. 5, a central portion of the filter bundle or 4 filters may have a downdraft reinforcement protrusion 251 formed therebetween.
The descending-air-flow reinforcement protrusion 251 may be formed in a downwardly protruding annular protrusion shape at a portion (central portion) where the 4 sub-inclined surfaces 231 are gathered. The descending air flow reinforcement protrusion 251 prevents the filter from being damaged by the air flow colliding against the filter when the air flow descends, and prevents the dust from being re-scattered by forming a stronger descending air flow at the center of the plurality of filters.
According to the above-described embodiments, it is expected that the air flowing into the dust collecting device will descend around the filter to prevent the dust from re-scattering, the descending air flow collecting part is formed at the filter bundle boundary to prevent the dust from scattering to other filter bundles, the filter will be prevented from being damaged by the descending air flow, the dust re-scattering prevention module can be mounted on the conventional dust collecting device, and the efficiency of the device can be improved without replacing the conventional dust collecting device.
The dust re-scattering prevention module of the filter dust collector and the dust collecting apparatus using the same described above are not limited to the structure and method of the above-described embodiments, and all or a part of the embodiments may be selectively combined from the above-described embodiments to implement various modifications.
