Problems solved by technology

[0005] However, there are differences in rigidity and durability between ceramic filters and filters using filter cloth made of fiber materials, so the method of installing them on the partition wall of the dust collection device will also be different
Therefore, in the dust collecting device, there is a problem that the selection range of the filter is limited.

no. 1 Embodiment approach 〕

[0023] One embodiment of the present invention will be described in detail below.

[0024] (the overall structure of the filter)

[0025] figure 1 It is a schematic diagram showing the filter 100 according to the first embodiment. The filter 100 has a vertically long shape as a whole. Most of the filter 100 constitutes a cylindrical filter unit 150 . The total length of the filter unit 150 is about 1 to 10 m. The diameter of the filter unit 150 is about 10 to 17 cm.

[0026] The filter 100 includes an attachment portion 160 on the top of the filter portion 150 . The filter part 150 is comprised from the filter cloth 101 formed in cylindrical shape. The bottom of the filter cloth 101 is closed, and the filter cloth 101 is a vertically long bag shape with an upper part opened. In addition, a frame (namely, a holder 120 ) for maintaining the shape of the filter cloth 101 is provided on the filter unit 150 .

[0027] The filter cloth 101 is made of heat-resistant material....

no. 2 Embodiment approach 〕

[0055] Another embodiment of the present invention will be described below. In addition, for convenience of description, components having the same functions as those described in the above-mentioned embodiments are denoted by the same reference numerals, and redundant descriptions are omitted.

[0056] The overall structure of the filter 200 according to the second embodiment is the same as that of the filter 100 according to the first embodiment, but the structure of the attachment part is different. Below, use Figure 4 The attachment part of the filter 200 is demonstrated in detail. exist Figure 4 In , the structure near the attachment part of the filter 200 and the simple plate 3 are shown.

[0057] The belt portion 202 is connected to the top of the cylindrical filter cloth 201 . Here, the band portion 202 is a band-shaped portion formed on the top of the cylindrical portion. The belt portion 202 may be formed by extending the filter cloth 201 directly, or may be f...

no. 3 Embodiment approach 〕

[0063] The overall structure of the filter 300 according to the third embodiment is the same as that of the filter 200 according to the second embodiment, but the structure of the attachment part is different. Below, use Figure 5 The attachment part of the filter 300 is demonstrated in detail. exist Figure 5 In , the structure near the attachment part of the filter 300 and the simple plate 3 are shown.

[0064] The belt portion 302 is connected to the top of the cylindrical filter cloth 301 . Here, the band portion 302 is a band-shaped portion formed on the top of the cylindrical portion. The belt portion 302 may be formed by extending the filter cloth 301 directly, or may be formed by connecting another cloth material. A detent 303 made of metal is fixed to the belt portion 302 . The detent 303 is an annular member that fits into the circular opening 3 a of the simple plate 3 . The bayonet pin 303 has elasticity, and when it fits in the opening part 3a, the filter clo...

Abstract

The present invention provides a filter replacement method of a dust collecting device capable of expanding the selection range of the filter and expanding the application range of the dust collecting device. The filter replacement method of the dust collecting device of the present invention includes the step of installing a second filter (100) instead of the first filter installed in the dust collecting device, and the first filter and the second filter have a cylindrical filter. The rigidity of the filter part (150) of the first filter and the filter part of the second filter is different from that of the attachment part (160) provided on the upper part of the filter part.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2019-019927 filed on February 6, 2019. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The present invention relates to a method for replacing a filter of a dust collecting device for collecting and separating dust or toxic gas from exhaust gas, the dust collecting device and the filter. Background technique [0003] In order to remove dust, toxic gases, etc. in the exhaust gas discharged from sewage sludge, waste incinerators, metal smelting equipment, etc., exhaust gas treatment equipment equipped with dust collectors in the form of partitions is used. In the partition type dust collecting device, the inside of the housing is divided into a dust collecting room and a clean room. Furthermore, the partition wall is provided with a filter which collects the dust contained in the filtering object gas which flows from the dust collect...
