DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting device for collecting dust and the like, and more particularly to a dust collecting device suitably used for sucking and collecting harmful dust such as dioxins.

[0002]

2. Description of the Related Art In recent years, aggressive environmental measures have been promoted, and harmful dusts such as dioxins generated in refuse incineration facilities have been regarded as a problem. In particular, when cleaning or repairing the incinerator of the refuse incineration equipment, there is a concern that dust such as dioxins remaining in the incinerator may deteriorate the working environment of the worker. Conventionally, when working in an incinerator with the refuse incineration facility stopped, the work has been performed while ventilating the inside of the incinerator using a ventilator for repair or the like installed in the refuse incineration facility in advance.

[0003]

The above-mentioned conventional ventilation equipment for repairs is extremely effective when ventilating a wide range of waste incineration equipment mainly including incinerators. However, there is a limit in the case of collecting dust locally in an incinerator, for example.

Accordingly, an object of the present invention is to provide a dust collecting apparatus having a high dust collecting ability such as dust.

[0005]

In order to solve the above-mentioned problems, a dust collector according to the present invention is configured as described in claim 1. Here, the terms described in claim 1, other claims and the detailed description of the invention are interpreted as follows. (1) “Dust and the like” includes not only dust itself but also various kinds of dust, dust, pollen, pathogens such as viruses, tobacco particles, and the like. (2) In the “step shape”, in addition to the step shape, for example, a plurality of plate-like pieces are slid in a parallel state, and another plate-like piece is arranged to protrude from one plate-like piece. Also includes the form. (3) The term “inclination” includes not only a linear gradient but also a curvilinear gradient.

According to the first aspect of the present invention, the porous baffle member is arranged so as to sequentially block the flow of air containing dust and the like, and the air containing dust and the like flows into the dust collecting section. After that, it comes into contact with the porous baffle member sequentially. Then, every time the air containing the dust or the like comes into contact with the baffle member, the dust or the like is sieved and collected by the hole of the baffle member. Therefore, by providing a baffle member having a hole having a diameter corresponding to dust to be collected,
A high dust collecting effect for dust and the like can be obtained. In addition, since the baffle members are arranged stepwise, a rectifying action can be given to the flow of air.

Further, the dust collecting apparatus of the present invention is configured as described in claim 2. According to the dust collecting device of the second aspect, the filter member of the dust collecting section is arranged inclined, and the filter member can be efficiently installed in a predetermined installation area. Therefore, it is possible to increase a contact area where air including dust and the like comes into contact with the filter member, and it is possible to effectively collect dust and the like by the filter member. In addition, the efficient arrangement of the filter member allows the dust collecting portion to be designed compact.

The dust collecting apparatus of the present invention is configured as described in claim 3. According to the dust collecting device of the third aspect, in the first dust collecting section, dust and the like are sieved and collected by the hole of the baffle member each time air including the dust and the like contacts the baffle member. In the second dust collecting section, the filter member is efficiently installed in a predetermined installation area to increase the contact area where air including dust and the like comes into contact with the filter member, and the filter member effectively removes the dust and the like. Can be collected. Since the first dust collecting unit and the second dust collecting unit are combined, dust and the like not collected by the baffle member of the first dust collecting unit flow into the second dust collecting unit and are collected by the filter member. You. Therefore, a high dust collecting effect of dust and the like can be obtained.

The dust collector of the present invention is configured as described in claim 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of a dust collector according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the dust collector of the present embodiment. 2 shows a side view of the dust collector of FIG. 1, and FIG. 3 shows a rear view of the dust collector of FIG. In the present embodiment, a case will be described in which air containing harmful dusts such as dioxins is taken in by a dust collector in an incinerator to collect dust, and then exhausted into the incinerator as clean air.

As shown in FIGS. 1 to 3, the dust collector 1 is formed in a box shape, and casters 3 are attached to four places on the bottom surface of the main body 2. On the back side of the main body 2, a handle 7 for movement is attached. Therefore, the operator can easily move the dust collecting device 1 by operating the handle 7. The casters 3 correspond to the self-propelled means of the present invention.

The main body 2 is formed in three vertical stages in the order of a first dust collecting part 10, a second dust collecting part 20, and a third dust collecting part 30 from below to above (in the figure). I have. On the front side of the main body 2, the inspection doors 16, 26, 3 are located at positions corresponding to the first dust collection unit 10, the second dust collection unit 20, and the third dust collection unit 30, respectively.
6 (each having a handle 16a, 26a, 36a) is provided, and the inspection doors 16, 26, 36 can be opened to inspect the inside of the dust collection units 10-30. In addition, a dust collecting box (not shown) for cleaning is installed on the lower surface (in the figure) of the first dust collecting section 10.

A lower position on the back side of the main body 2 (the first dust collecting section 1)
0) is provided with a fan type blower (intake port) 4,
An exhaust port 8 is provided on the upper surface of the main body 2 (third dust collecting section 30). Therefore, the air flows from the intake port of the blower 4 in FIG.
Air is taken in the direction of the arrow 40 in the middle, and is exhausted from the exhaust port 8 in the direction of the arrow 46 in the figure. By removing the upper mounting plate 9 on the back side of the main body 2, the exhaust port can be secured on the back side of the main body 2. On the back side of the main body 2, a differential pressure gauge 5 for displaying the pressure loss (differential pressure) of the second dust collecting section 20,
An on / off switch 6 for the blower 4 is provided.

Next, the first dust collector 10, the second dust collector 20,
The configuration inside the third dust collection unit 30 will be described in detail with reference to FIGS. 1 to 5. FIG. 4 is a perspective view of a baffle member of the first dust collection unit 10, and FIG. 5 is a perspective view showing a configuration of the second dust collection unit 20.

First, the first dust collecting section 10 is provided with four baffle members 11 as shown in FIG. The baffle member 11 is formed of a plate-like piece, and has a vertical portion 12 and inclined portions 13 and 14. The inclined portions 13 and 14 are formed to be inclined by an angle θ with respect to a plane orthogonal to the vertical portion 12. In addition, a plurality of holes 15 (for example, a circular shape having an inner diameter of 4 mm) are formed at predetermined intervals over the entire surface of the baffle member 11. Each of the baffle members 11 is arranged in parallel with each other so that each vertical portion 12 is orthogonal to the flow of air sucked from the air inlet of the blower 4, and a predetermined gap is formed between the baffle members 11. Have been.
Note that the state in which the baffle members 11 are arranged in this way corresponds to “sequentially interrupting the flow of air” of the present invention.

As shown in FIG. 2, the more the baffle member 11 is located farther from the intake port of the blower 4, the more (in the figure)
It is arranged shifted upward. The state in which the baffle member 11 is arranged in this way corresponds to the “stepped” of the present invention. Since the baffle member 11 is provided with the inclined portions 13 and 14 and the baffle member 11 is arranged in a stepped manner, the flow of the air passing through the first dust collection portion 10 is adjusted so that the air flows smoothly into the second dust collection portion 20. Can be.

As shown in FIG. 5, the second dust collecting section 20 includes
A flat plate-like wire netting plate 21 and a filter plate 24 having substantially the same size are provided. Frame 22 of wire mesh plate 21
A wire mesh 23a is attached to the
5 is provided with a filter medium 23b. Then, two sets of the wire mesh plate 21 and the filter plate 24 are overlapped to form one set of filter members 28, and a total of eight sets of filter members 28 are installed.

A guide rail 27 corresponding to each filter member 28 is provided, and the wire mesh plate 21 and the filter plate 24 are individually slidable along the guide rail 27. For example, the wire mesh plate 21 and the filter plate 24 can be easily removed by sliding in the direction of arrow 50 in FIG. Thus, the wire mesh plate 21
In addition, since the filter plate 24 is detachably configured, it is possible to easily cope with the case where the wire mesh plate 21 and the filter plate 24 are cleaned.

Each of the filter members 28 is disposed so as to be linearly inclined with respect to the flow of air containing dust (in the direction of arrow 41 in FIG. 2).
8 are arranged in such a manner that the inclination of them is continuous without interruption (a form in which no gap is formed in the flow of air). Because the filter member 28 is arranged at an angle,
The filter member 28 can be efficiently installed in the cross section of the second dust collection unit 20. Therefore, the contact area where the air containing the dust contacts the filter member 28 can be increased. In addition, since the filter member 28 is formed in an inclined shape, when the switch 6 is turned off to stop dust collection, dust such as dioxins collected easily falls to the first dust collection unit 10 side. Therefore, the filter member 28
Is easy to clean.

Further, since the filter member 28 is arranged so as to have a continuous inclination, the filter member 28 can be brought into uniform contact with air. , The pressure loss (differential pressure) is reduced, and the flow rate of air passing through the second dust collecting section 20 can be increased.

The wire netting plate 21 is provided on the lower surface side of the filter member 28 (on the side of the first dust collecting portion 10).
The air passing through 0 is arranged so as to contact the wire mesh plate 21 before the filter plate 24. Further, a predetermined interval t is formed between the wire mesh 23a of the wire mesh plate 21 and the filter medium 23b of the filter plate 24. Since the wire mesh plate 21 and the filter plate 24 of the filter member 28 are arranged as described above, dust such as dioxins can be collected between the wire mesh 23a and the filter medium 23b. By changing the interval t between the wire mesh 23a and the filter medium 23b, the amount of dust collected by the filter member 28 changes.

Further, each of the filter members 28 has a horizontal surface which is the same as that of the baffle member 11 installed in the first dust collection unit 10.
Are arranged so as to be substantially parallel and orthogonal to the horizontal plane of the vertical portion 12. By arranging the filter member 28 in this manner, dust in the air that has passed through the baffle member 11 comes into uniform contact with the filter member 28. Accordingly, it is possible to prevent the clogging of dust or the like from being biased depending on the position where the filter member 28 is disposed, and it is possible to perform dust collection using the filter 28 member efficiently.

Next, a filter member 31 is provided in the third dust collecting section 30. The filter member 31 is disposed such that the dust collection surface 31a is orthogonal to the flow of air containing dust (arrow 45 in FIG. 2).

Next, the operation of the dust collector 1 and the dust collector 1
The flow of air in the inside will be described in detail with reference to FIGS. FIG. 6 is an explanatory diagram showing the arrangement of the baffle members, and FIG. 7 is an explanatory diagram showing the arrangement of the filter members. In FIG. 6, four baffle members 1 are shown for explanation.
Only two pieces out of one are described, and the number of holes 15 is omitted.

First, predetermined hoses are connected to the intake port and the exhaust port 8 of the blower 4 and both hoses are inserted into the incinerator. Then, the switch 6 is turned on to start the blower 4. As a result, the first dust collecting section 10 has the configuration shown in FIG.
An air flow in the direction of the arrow 40 is formed. Then, as shown in FIG. 6, in the first dust collection unit 10, air containing dust such as dioxins collides with the surface of the baffle member 11 on the intake port side. Then, the dust that cannot pass through the hole 15 falls downward (in the figure) and falls into a dust collection box (not shown).
Will be collected. Further, for example, the dust that has passed through the hole 15 of the vertical portion falls in the direction of the arrow 42 in the figure, passes through the hole 15 of the next baffle member 11 (the direction of the arrow 43), and is arranged stepwise and inclined. Due to the effect of the baffle member 11 having the portions 13 and 14, the baffle member 11 is separated from the one that rises with the flow of air in the direction of arrow 41. Dust can be separated in this manner because a predetermined gap is formed between the baffle members 11 as described in the configuration of the baffle members 11. And finally, 4
Due to the effect of the one baffle member 11, the baffle member 11 is separated into one that is collected in the dust collection box and one that flows into the second dust collection part 20.

In the dust collector 1 of the present embodiment, the baffle member 1 is located at a position away from the air inlet of the blower 4.
The position of the baffle member 11 is shifted upward in FIG. 6, but the arrangement shape is not limited as long as the baffle members 11 are arranged stepwise. For example, the baffle member 11 located farther from the air inlet of the blower 4 may be arranged to be shifted downward (in FIG. 6). This is the first dust collection unit 10 shown in FIG.
This is because, as can be seen from the shape, air taken in the direction of the arrow 40 flows out in the direction of low pressure (toward the second dust collecting section 20) regardless of the arrangement of the baffle member 11 and the like.

Next, the air flowing into the second dust collecting section 20 moves in the direction of arrow 41 in FIG.
Collision 8 The dust such as dioxins is deposited on the wire mesh 23a of the wire mesh plate 21 and the filter material 23b of the filter plate 24.
(Interval t). The dust that has passed through the filter medium 23b of the filter plate 24 flows into the third dust collection unit 30 along with the flow of air in the directions of arrows 44a and 44b. When the indicated value of the differential pressure gauge 5 becomes equal to or more than an appropriately determined value, the switch 6 is turned off and the blower 4 is stopped. Then, the inspection door 26 is opened to open the wire mesh plate 21 and the filter plate. 24 is cleaned.

Next, the air containing dust that has passed through the second dust collector 20 moves in the direction of arrow 45 in FIG. 2 and collides with the filter member 31 of the third dust collector 30. And the second
Dust that could not be collected by the filter member 28 of the dust collection unit 20 is collected by the filter member 31 and exhausted as clean air from the exhaust port 8 in the direction of the arrow 46 (inside the incinerator).

According to the dust collector 1 configured as described above, a high dust collecting effect can be obtained by providing the baffle member 11 having a hole having a diameter corresponding to dust such as dioxins. Also, four pieces of baffle member 1
Because of the provision of 1, it is possible to obtain an even higher dust collection effect than in the case where one piece of baffle member is provided, for example.

Further, the filter members 28 are arranged so as to be linearly inclined with respect to the flow of air containing dust, and furthermore, are arranged in such a manner that the inclination of the filter members 28 is continuous. In addition to increasing the contact area where the dust-containing air contacts the filter member 28, the filter member 28 can be uniformly contacted with the dust-containing air, and further passes through the second dust collecting unit 20. The flow rate of passing air can be increased.

The dust collecting device 1 is connected to the first dust collecting section 10 and the second dust collecting section 10.
Since the dust collecting unit 20 and the third dust collecting unit 30 are configured in three stages in this order, a high dust collecting effect can be obtained. Further, since the baffle member 11 is provided in the first dust collection unit 10, coarse particles of dust are removed (collected) by the baffle member 11, and
Clogging of the filter member 28 of the dust collecting section 20 can be prevented. Therefore, the dust collector 1 can be used efficiently.

Further, since the casters 3 are attached to the bottom surface of the main body 2, the dust collector 1 can be relatively easily moved and used.

It should be noted that the present invention is not limited to the above-described embodiment, and various applications and modifications are conceivable. In the above embodiment, the dust collecting apparatus 1 is configured by combining the first dust collecting section 10, the second dust collecting section 20, and the third dust collecting section 30 in this order. It is also possible to configure only the two dust collecting units 20. Further, the dust collecting apparatus 1 is divided into a first dust collecting section 10, a second dust collecting section 20, and a third dust collecting section 3.
The three dust collectors are arranged in three vertical rows in the order of 0.
0 can also be arranged in the horizontal direction.

Although the dust collector 1 for collecting dust such as dioxins in the air in an incinerator has been described, the present invention can also be applied to a dust collector for collecting various dusts in various facilities. it can. In that case, the first dust collector 1
The shape, inner diameter, number, etc. of the holes 15 of the baffle member 11 of 0,
The filter member 28 of the second dust collector 20 and the third dust collector 3
This can be dealt with by appropriately changing the type of the zero filter member 31 and the materials of various constituent members as needed.

Although the first dust collecting section 10 is provided with the four baffle members 11, the number of the baffle members can be variously changed as required. Further, the shape, the inner diameter, the number, and the like of the holes 15 of the baffle member 11 can be appropriately changed. Further, the inclination angle θ of the inclined portions 13 and 14, the degree of displacement of each baffle member 11, and the like can be variously changed. Further, a step-like baffle member can be formed by one piece of member.

Further, although eight sets of filter members 28 are provided in the second dust collecting section 20, the number and size of the filter members 28 can be variously changed as necessary. In addition, wire mesh 23
The distance t between a and the filter medium 23b can be changed as appropriate. Further, the types and the like of the filter members 28 and 31 are not limited, and can be variously changed as needed.

Although the wire netting plate 21 and the filter plate 24 are both formed in a flat plate shape, the filter member 28 is arranged linearly inclined, but may be curvedly inclined. Further, the inclination angle of the filter member 28 can be appropriately changed.

Although the wire netting plate 21 and the filter plate 24 are configured to be detachable by sliding on the guide rail 27, the arrangement of the wire netting plate 21 and the filter plate 24 is not limited, and may be variously changed as necessary. be able to.

Although the first dust collecting section 10 is provided with the fan type blower 4 for sucking air, the means for sucking air can be variously changed as required. For example,
It may be an electric dust collection type. Further, the blower 4 may be installed on the exhaust port 8 side of the third dust collection unit 30.

Although the caster 3 is mounted on the bottom surface of the main body 2 so that the dust collecting device 1 can be freely moved, the means for moving the dust collecting device 1 is not limited. For example, it may be a wheel on which a driving device is mounted.
