Description
The present application claims priority based on Japanese patent application No. 2016-. The entire contents of this Japanese application are incorporated by reference into this specification.
Technical Field
The present invention relates to a member for protecting and mounting a ceramic filter, and for example, relates to a member for protecting and mounting a ceramic filter used in a partition type dust collecting apparatus.
Background
In order to remove coal dust, toxic gas, and the like from exhaust gas discharged from sewage sludge incinerators, incinerators for garbage such as municipal waste, incinerators for industrial waste, metal smelting facilities, and the like, exhaust gas treatment facilities including a partition wall type dust collecting device are used.
In the partition wall type dust collecting device provided in the exhaust gas treatment facility, the soot is separated on the outer surface of the partition wall and accumulated on the collecting body, except for the initial stage where the amount of the soot to be collected is small. The dust collection rate is very high regardless of the particle diameter but the pressure loss in the collection body increases with the passage of time, so that it is necessary to remove the accumulated soot at appropriate intervals to maintain continuous operation.
As a method for removing the accumulated soot, the following methods are known: a method of shaking off the soot accumulated on the outer surface by instantaneously blowing compressed air from the upper part of the filter medium to the inner surface by a backwashing mechanism such as a pulse jet method.
However, the collector of the partition type dust collecting apparatus widely uses a bag filter of a filter medium made of natural fibers or synthetic fibers, but has a problem of limited use temperature (i.e., limited temperature at which exhaust gas can be treated).
As a filter medium capable of coping with exhaust gas of low temperature to high temperature by overcoming the problem, a ceramic filter has been used in recent years.
However, although the ceramic filter has very high heat resistance (about 900 ℃ C. at the maximum) and is not limited by the use temperature (that is, the temperature at which exhaust gas can be treated is not limited), the ceramic filter has a problem that it is easily broken by external factors such as vibration and impact at the time of transportation, installation, and operation, and an earthquake because the ceramic filter has very brittle characteristics and low strength.
Further, the ceramic filter is limited in length of a product compared to a bag filter using a filter medium made of natural fiber or synthetic fiber due to manufacturing reasons, and thus has the following problems: in order to have the same exhaust gas treatment capacity as the bag filter, it is necessary to use a higher number of filter media than the bag filter.
Therefore, various protection mechanisms for reinforcing the ceramic filter have been proposed (see patent documents 1 to 3).
Among them, patent document 1 describes a combined fixing device for a ceramic filter, which vertically presses the ceramic filter between upper and lower support members by an elastic force of a spring provided at a lower end of the ceramic filter. Further, patent document 2 describes a combined fixing device for a ceramic filter, in which a receiving table and an upper plate are coupled and fastened by a coupling mechanism having a spring, thereby fixing the ceramic filter via a lower packing and an upper packing.
In addition, although the combined fixing device for a ceramic filter described in patent documents 1 to 2 can achieve a certain object of reinforcing the ceramic filter, it is necessary to perform maintenance on the ceramic filter on a module-by-module basis, and particularly, when the ceramic filter is used, the number of filter media used is increased compared to a bag filter, and thus, there is a problem that maintenance requires a lot of time.
On the other hand, patent document 3 describes a holder for reinforcing a ceramic filter from an inner surface of a hollow portion of the ceramic filter. Specifically, as shown in fig. 4, the holding member R is inserted into the hollow portion of the ceramic filter 1 through the opening portion that opens into the hollow portion of the ceramic filter 1, abuts against the inner surface of the hollow portion of the ceramic filter 1, and presses the inner surface outward, thereby reinforcing the ceramic filter 1.
It is considered that the holder R of the reinforced ceramic filter 1 described in patent document 3 can achieve a certain object of reinforcing the ceramic filter 1 by one piece.
However, in the ceramic filter 1, for manufacturing reasons, the inner surface of the hollow portion of the ceramic filter 1 has poor dimensional accuracy and has variations in dimensions. Therefore, even if the holder R is accurately formed to a size in consideration of thermal expansion, there is a problem that the ceramic filter 1 is damaged or cracked due to thermal expansion of the holder R.
In addition, the ceramic filter 1 is generally used by fixing the flange 11 of the ceramic filter 1 to a plate member made of a steel plate called an ejector plate 2, which partitions the inside of the housing of the partition wall type dust collecting device and has a plurality of holes 21 for mounting the ceramic filter 1, but has the following problems: due to distortion in the production of the flange 11 of the ceramic filter 1 or deformation of the ejector plate 2 caused by operation at high temperatures, a gap is likely to be formed between the flange 11 of the ceramic filter 1 and the ejector plate 2 beyond the sealing ability of the sealing member 3, and the sealing performance is lowered (thereby, soot, toxic gas, and the like contained in exhaust gas are not removed by the ceramic filter 1 but leak to the cleaning chamber side partitioned by the ejector plate 2 in the housing of the partition type dust collecting apparatus through the gap), or the ceramic filter 1 is broken or cracked due to an uneven load.
In addition, in the conventional partition wall type dust collecting device, the diameter of the hole 21 for mounting the ceramic filter 1 is set to be close to the diameter of the ceramic filter 1, and thus even if a gap is generated between the flange 11 of the ceramic filter 1 and the ejector plate 2, the leakage amount of the exhaust gas can be suppressed. However, when the ejector plate 2 is manufactured in this manner, when the ceramic filter 1 is installed, the ceramic filter 1 having a small strength is likely to be damaged by contact with the ejector plate 2, and thus there is a problem that the workability in installation is lowered.

Disclosure of Invention
The present invention has been made in view of the problems of the ceramic filter used in the conventional partition wall type dust collecting device, and an object of the present invention is to provide a member for protecting and mounting a ceramic filter, which can reinforce and manufacture a ceramic filter having an unstable size in a unit of one ceramic filter, and can stably mount the ceramic filter to an ejector plate.
In order to achieve the above object, a ceramic filter protective mounting member according to the present invention is a ceramic filter protective mounting member for mounting a ceramic filter to an ejector plate, the ceramic filter protective mounting member comprising: a fixing member which is present between the flange of the ceramic filter and the ejector plate and is mounted to the ejector plate; a support member disposed on an outer surface of the ceramic filter on a side opposite to the flange to support the ceramic filter; and a connecting member connecting the fixing member and the support member.
At this time, the support member may be disposed at the bottom of the ceramic filter to support the ceramic filter.
And, the support member may fasten an outer circumferential surface of the ceramic filter to support the ceramic filter.
The connecting member may include a tension applying member for applying a tension to the ceramic filter in a longitudinal direction thereof.
Also, the fixing member may be formed to have an annular shape of a hole into which the ceramic filter is inserted, and a diameter of the hole is smaller than a diameter of a hole of the ejector plate for mounting the ceramic filter.
A load support member that supports the load of the ceramic filter placed in a horizontal position via the support member or the connection member may be attached to the support member or the connection member.
Effects of the invention
According to the ceramic filter protection mounting member of the present invention, the ceramic filter protection mounting member is composed of: a fixing member which is present between the flange of the ceramic filter and the ejector plate and is mounted to the ejector plate; a support member disposed on an outer surface of the ceramic filter on a side opposite to the flange to support the ceramic filter; and a connecting member that connects the fixing member and the support member. By attaching the ceramic filter to the ejector plate by using the ceramic filter protective attachment member, the ceramic filter having an unstable size can be reinforced and manufactured for each unit, and specifically, the ceramic filter can be stably attached to the ejector plate while reliably absorbing vibration and impact at the time of transportation, installation, and operation, and impact force applied by external factors such as an earthquake or thermal stress applied by deformation of the member due to temperature change at the time of operation.
Further, since the support member is disposed at the bottom of the ceramic filter to support the ceramic filter, even if the ceramic filter is cracked or broken by any chance, the cracked or broken ceramic filter is supported by the support member disposed at the bottom of the ceramic filter, and thus the crack can be prevented from being enlarged or the broken ceramic filter can be prevented from dropping. Further, it is possible to prevent soot, toxic gas, and the like contained in the exhaust gas from instantaneously leaking to the cleaning chamber side due to a large opening formed in a portion of the ceramic filter where breakage occurs.
Further, since the support member fastens the outer peripheral surface of the ceramic filter to support the ceramic filter, the same operational effect as that obtained when the support member is disposed at the bottom of the ceramic filter can be obtained for the portion of the ceramic filter supported by the support member, and the ceramic filter can be supported by a simple structure.
Further, since the connecting member includes a tension applying member that applies tension in the longitudinal direction of the ceramic filter, it is possible to reliably absorb vibration and impact during transportation, installation, and operation, and impact force applied by an external factor such as an earthquake or thermal stress applied by deformation of the member due to temperature change during operation, and to stably support the ceramic filter.
Further, since the fixing member is formed in an annular shape having a hole into which the ceramic filter is inserted, and the diameter of the hole is smaller than the diameter of the hole of the ejector plate for mounting the ceramic filter, it is possible to eliminate an accident that the ceramic filter is damaged by contact with the ejector plate when the ceramic filter is installed, and to improve the operability at the time of installation.
Further, since the load support member for supporting the load of the ceramic filter placed in a lateral direction via the support member or the connection member is attached to the support member or the connection member, the ceramic filter can be stably placed in a lateral direction.

Detailed Description
Hereinafter, embodiments of the member for protecting and mounting a ceramic filter according to the present invention will be described with reference to the drawings.
Fig. 1 shows a first embodiment of a member for protecting and mounting a ceramic filter according to the present invention.
The protective attachment member 4 of the ceramic filter 1 is used to fix and attach the flange 11 of the ceramic filter 1 to a plate member made of a steel plate called an ejector plate 2, which divides the inside of the housing of the partition wall type dust collecting device and has a plurality of holes 21 for attaching the ceramic filter 1.
The ceramic filter protective attachment member 4 is composed of: a fixing member 41 which is present between the flange 11 of the ceramic filter 1 and the ejector plate 2 and is attached to the ejector plate 2; a support member 42 that is disposed on an outer surface of the ceramic filter 1 on the side opposite to the flange and supports the ceramic filter 1; the connecting member 43 connects the fixing member 41 and the support member 42.
In this case, a conventional common partition wall type dust collecting device in which the ceramic filter 1 is attached to the ejector plate 2 partitioning the inside of the housing can be widely used.
At this time, in particular, when newly installed, the shape of the hole 21 formed in the ejector plate 2 for mounting the ceramic filter 1 may be formed larger than a conventional hole in consideration of the relationship with the fixing member 41 for protecting the mounting member 4 described later.
This eliminates the possibility of breakage of the ceramic filter 1 due to contact with the ejector plate 2 when the ceramic filter 1 is installed, and improves the operability during installation.
As the ceramic filter 1, a ceramic filter 1 having a bottom (which may be an integrated ceramic filter as in the present embodiment or a ceramic filter having a bottom opening closed by another member) having a flange 11 at an opening portion, which is commonly used in the conventional partition wall type dust collecting apparatus, can be used.
The fixing member 41 is constituted by a ring-shaped member having a hole 41a into which the main body portion of the ceramic filter 1 is inserted and made of metal such as iron or stainless steel.
The hole 41a of the fixing member 41 is preferably formed to have a diameter smaller than the diameter of the hole 21 of the ejector plate 2 for mounting the ceramic filter 1 and as close as possible to the diameter of the ceramic filter 1.
This eliminates the risk of breakage of the ceramic filter 1 due to contact with the thimble plate 2 when the ceramic filter 1 is installed, improves the operability during installation, and suppresses the amount of soot, toxic gas, and the like contained in the exhaust gas that leaks into the cleaning chamber side partitioned by the thimble plate 2 in the housing of the partition wall type dust collecting device through the gap without being removed by the ceramic filter 1 even when the gap is generated between the flange 11 of the ceramic filter 1 and the fixing member 41.
The fixing member 41 is installed on the ejector plate 2 by the fixing member 41 being provided on the ejector plate 2 via the seal member 31 such that the fixing member 41 exists between the flange 11 of the ceramic filter 1 and the ejector plate 2, and then the fixing member 41 is mounted on the ejector plate 2 by the fixing member 5.
Here, the sealing member 32 is also present between the flange 11 of the ceramic filter 1 and the fixing member 41.
The fixing member 5 is configured to absorb deformation of the components due to temperature change during operation by implanting a bolt member 52 such as a stud bolt provided on the ejector plate 2 to fasten the pressure plate 51 provided in contact with the upper end surface of the ceramic filter 1 (flange 11) and providing a spring member 53 between the pressure plate 51 and the fixing member 41.
This can prevent the ceramic filter 1 from being damaged or cracked due to an uneven load generated by the deformation of the components, particularly the ejector plate 2.
Since the pressure plate 51 constituting the fixing member 5 includes the venturi tube 6 inserted into the hollow portion of the ceramic filter 1 through the opening portion of the ceramic filter 1, compressed air can be blown into the hollow portion of the ceramic filter 1 through the venturi tube 6, and backwashing for shaking off the soot accumulated on the outer surface of the ceramic filter 1 can be performed.
The support member 42 is made of metal such as iron or stainless steel, and is configured to be disposed on an outer surface of the ceramic filter 1 on the side opposite to the flange so as to be able to support the ceramic filter 1.
Specifically, as shown in the present embodiment, the support member 42 may be disposed at the bottom of the ceramic filter 1 to support the ceramic filter 1.
Therefore, the support member 42 is formed in a hemispherical shape (cup shape) along the outer peripheral shape of the bottom portion of the ceramic filter 1, but wires or strips may be crossed to support the bottom portion of the ceramic filter 1.
In the case of using a ceramic filter 1 in which the bottom opening of the cylindrical ceramic filter 1 is closed with another member, the other member closing the bottom opening may also serve as the support member 42.
Thus, even if a crack or breakage occurs in the ceramic filter 1, since the ceramic filter 1 in which the crack or breakage occurs is supported by the support member 42 disposed at the bottom of the ceramic filter 1, the crack can be prevented from being enlarged, and the broken ceramic filter 1 can be prevented from falling off. Further, it is possible to prevent soot, toxic gas, and the like contained in the exhaust gas from instantaneously leaking to the cleaning chamber side due to a large opening formed at a position where the ceramic filter 1 is broken.
As shown in fig. 2(a) and 2(b) of the embodiment 2 of the member for protecting and mounting a ceramic filter according to the present invention, the support member 42 may be configured to support the ceramic filter by fastening the outer peripheral surface of the ceramic filter 1 at an appropriate position in the longitudinal direction of the ceramic filter 1.
Therefore, the support member 42 is formed in an annular shape along the outer peripheral surface shape of the ceramic filter 1, and the outer peripheral surface of the ceramic filter 1 is fastened by a fastening member 42a constituted by a spring member, a clamp member, or the like.
In consideration of the operation of the ceramic filter 1 against vibration or the like, the portion of the ceramic filter 1 fastened by the support member 42 may be set to a position of 1/2 or more, preferably 2/3 or more, of the entire length of the ceramic filter 1 with respect to the flange 11.
As a result, the same operational effects as those obtained when the support member 42 is disposed at the bottom of the ceramic filter 1 can be obtained for the portion of the ceramic filter 1 supported by the support member 42, and the ceramic filter 1 can be supported by a simple structure.
In order not to obstruct the gas flow of the ceramic filter 1, specifically, in order not to obstruct the removal or backwashing of soot, toxic gas, and the like in the exhaust gas, the connecting member 43 is made of a wire, a strip, or a chain made of metal such as iron or stainless steel, and a plurality of (for example, about 3 to 6) connecting members 43 are arranged at the same angular intervals to connect the fixing member 41 and the supporting member 42. In this case, it is preferable that the fixing member 41 and the supporting member 42 are connected so that the connecting member 43 is in a state of being applied with tension.
Further, a tension applying member 43a made of a spring member for applying tension to the ceramic filter 1 in the longitudinal direction may be provided at an appropriate position of the connecting member 43 (on the side of the support member 42 in the present embodiment).
The tension applying member 43a can reliably absorb vibration and impact at the time of transportation, installation, and operation, and impact force applied by an external factor such as an earthquake or thermal stress applied by deformation of the member due to temperature change at the time of operation, and can stably support the ceramic filter 1.
In the above embodiment, the example in which the ceramic filter 1 is used in the vertical direction was described, but the ceramic filter 1 may be used in the horizontal direction by using the protective mounting member 4 of the ceramic filter.
In this case, as shown in fig. 3, which is a 3 rd embodiment of the ceramic filter protective mounting member according to the present invention, a load support member for supporting a load of the ceramic filter 1 placed transversely through the support member 42 or the connection member 43 may be mounted on the support member 42 or the connection member 43, and specifically, a load support member 71 for supporting a load of the ceramic filter 1 from above or a load support member 72 for supporting a load of the ceramic filter 1 from below may be mounted.
This enables the ceramic filter 1 to be stably placed in the horizontal direction.
As described in the above embodiments, by attaching the ceramic filter 1 to the ejector plate 2 by the ceramic filter protective attachment member 4, the ceramic filter 1 having an unstable size can be reinforced and manufactured on a unit basis, and specifically, the ceramic filter 1 can be stably attached to the ejector plate 2 while reliably absorbing vibration and impact at the time of transportation, installation, and operation, and impact force applied by external factors such as an earthquake or thermal stress applied by deformation of the member due to temperature change at the time of operation.
Therefore, it is preferable that the protective mounting member 4 of the ceramic filter is mounted in advance not only at the time of operation but also at the time of transportation or installation of the ceramic filter 1, thereby absorbing vibration and impact at the time of transportation or installation to prevent cracking or breakage of the ceramic filter 1.
Although the ceramic filter protective mounting member according to the present invention has been described above with reference to a plurality of embodiments, the present invention is not limited to the structure described in the above embodiments, and the structure may be appropriately changed without departing from the gist of the present invention, and for example, the structures described in the respective embodiments may be appropriately combined.
Further, the ceramic filter protective attachment member of the present invention is not dependent on the basic structure of the partition type dust collecting device such as the ejector plate, and therefore, can be easily applied not only to a newly installed partition type dust collecting device but also to an already installed partition type dust collecting device.
The ceramic filter protection mounting member of the present invention has the following characteristics: the ceramic filter with unstable size can be reinforced and manufactured by taking one ceramic filter as a unit, and the ceramic filter can be stably installed on the ejector plate. Therefore, the ceramic filter can be suitably used as a member for protecting and mounting a ceramic filter of a partition type dust collector.
