Parts for protective installation of ceramic filters

Abstract

PROBLEM TO BE SOLVED: To provide a protection attachment member of a ceramic filter which can reinforce the ceramic filter having an unstable manufacturing dimension one by one and enables the ceramic filter to be stably attached to a thimble plate.SOLUTION: A protection attachment member 4 of a ceramic filter comprises: a fixing member 41 which is disposed between a flange 11 of a ceramic filter 1 and a thimble plate 2 and attached to the thimble plate 2; a support member 42 which is disposed on an anti-flange side outer surface of the ceramic filter 1 and supports the ceramic filter 1; and a connection member 43 which connects the fixing member 41 with the support member 42.SELECTED DRAWING: Figure 1

Description

[0001] This application claims priority based on Japanese Patent Application No. 2016-145336 filed on July 25, 2016. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The present invention relates to a component for protection and installation of a ceramic filter, for example, to a component for protection and installation of a ceramic filter used in a partition type dust collector. Background technique [0003] In order to remove coal dust, toxic gases, etc. in the exhaust gas discharged from sewage sludge incinerators, municipal garbage incinerators, industrial waste incinerators, metal smelting equipment, etc., use exhaust gas treatment with a partition type dust collector equipment. [0004] In the partition-type dust collector of this waste gas treatment facility, coal dust is separated on the outer surface of the partition and accumulated on the collection body except in the initial stage when the collected...

Problems solved by technology

[0015] On the other hand, due to manufacturing reasons of the ceramic filter 1, the dimensional accuracy of the inner surface of the hollow part of the ceramic filter 1 is poor, and there are variations in dimensions.

Therefore, even if the size of the retainer R is accurately manufactured in consideration of thermal expansion, there may be problems such as damage or cracking of the ceramic filter 1 due to thermal expansion of the retainer R.

[0016] In addition, the ceramic filter 1 usually fixes the flange 11 of the ceramic filter 1 in the frame of the partition type dust collector and has a plurality of holes 21 for installing the ceramic filter 1, which is called a thimble. Plate 2 is used on a plate member made of steel plate, but it has the following problems: due to distortion when manufacturing flange 11 of ceramic filter 1 or deformation of ejector plate 2 caused by operation at high temperature, etc., it is easy to protrude beyond sealing member 3. The sealing ability of the ceramic filter 1 produces a gap between the flange 11 and the thimble plate 2, so that the sealing performance is reduced (thereby, the coal dust and toxic gas contained in the exhaust gas will not be removed by the ceramic filter 1, Instead, it leaks through the gap to the side of the clean room partitioned by the ejector plate 2 in the frame of the partition type dust collector), or the ceramic filter 1 is damaged or cracked due to partial load

However, if the ejector plate 2 is produced in this way, when the ceramic filter 1 is installed, accidents that the ceramic filter 1 with low strength will come into contact with the ejector plate 2 and be damaged easily occur, so there is a problem that the operability at the time of installation is reduced.
