Abstract

(57) [Summary] [Purpose] To improve the service life of a leaf disk filter element for a tar pitch filter by making it possible to easily and reliably perform regeneration processes such as removal of pitch solids and cleaning. [Structure] A filter element is constructed by placing perforated plates on both sides of a wire mesh and sintered filter media on the outside thereof, and its outer periphery is fixed with a rim that is bent into a U-shaped cross section. do. By removing this rim, the element can be disassembled.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to leaf disc filter elements for tar pitch filters. It is something.

0002

[Conventional technology]

Leaf disc filter elements used in tar pitch filters include: Perforated plates of approximately the same shape are placed on both outsides of the donut-shaped wire mesh, and It is known that a sintered filter media of approximately the same shape is arranged on the side. this If the tar pitch passes through the filter media and enters the wire mesh area, the tar pitch will be filtered out. is then passed through its inner opening and sent out of the aircraft.

0003 In this conventional example, the outer periphery of the leaf disc filter element with the above structure is It is welded and fixed all around.

0004

[Problem that the idea aims to solve]

By the way, with the leaf disc filter element mentioned above, after long-term use, If clogging occurs with pitch solids, it is very difficult to remove and clean the pitch solids. It has the disadvantage of being. In other words, conventionally, leaf disc filter elements Crush the pitch solids inside and outside by hitting it from the outside, and then release the crushed pitch from the inside opening. However, depending on this method, it is not possible to make it into a reusable state. This is because it is difficult to remove pitch solids. Therefore, the above Lee Fdisk filter elements are mostly used in a so-called disposable manner. Common.

[0005] This invention was made to solve the above-mentioned conventional drawbacks, and its purpose was to can easily and reliably perform regeneration processes such as removal of pitch solids and cleaning. Therefore, the leaf disc filter for tar pitch filters can significantly improve the service life. The objective is to provide router elements.

[0006]

[Means to solve the problem]

Therefore, with this devised leaf disc filter element for tar pitch filters, A perforated plate is placed on both sides of a wire mesh, and a sintered filter media is placed on the outside of the perforated plate. A leaf disc filter for tar pitch filters with a roughly donut plate arrangement. The outer periphery of the element is formed by a rim that is bent into a roughly U-shaped cross section. It is characterized by being stationary.

[0007]

[Effect]

In the above leaf disc filter element for tar pitch filter, the rim is cut off. By removing the wire mesh, perforated plate, and filter media, you can disassemble them individually. Recycling processes such as removal of solid matter and cleaning can be performed easily and reliably. In addition, the above-mentioned recycling process After processing, the above-mentioned wire mesh, perforated plate, and filter media are re-processed by rim processing. Fix the wires, etc. to each other and reuse them.

[0008]

【Example】

In Fig. 1, 1 is a wire mesh, and this wire mesh 1 is donut-shaped, and Perforated plates 2, 2 having substantially the same shape are arranged on both lower sides. Furthermore, the perforated plates 2, 2 Sintered donut-shaped filter media 3, 3 are arranged on the outside. Na Hubs 4, 4 are attached to the inner peripheral portions of the filter media 3, 3. Also the same In the figure, 5 indicates a spacer.

[0009] The outer periphery of the filter media 3, 3 is bent to have a roughly U-shaped cross section. A rim 6 is attached, and this rim 6 connects the perforated plates 2 and 2. The outer peripheries of the router media 3 and 3 are fixed in a pressed state using the so-called caulking method. There is.

0010 The above wire mesh 1, perforated plates 2, 2, filter media 3, 3, hub 4, and spacer 5 is preferably made of stainless steel such as SUS304 in consideration of corrosion resistance. Moreover, the rim 6 is made of aluminum alloy, copper alloy, etc. in consideration of workability. Although it is preferable to form such a structure, the present invention is not particularly limited thereto.

[0011] The leaf disc filter element shown above has multiple sheets stacked vertically. Each leaf disc filter element is attached to the filter in the same state. In the filter media 3, the tar pitch starts from the side surface of the filter media 3, 3. Pass through the router media 3, 3 and the perforated plates 2, 2 and reach the wire mesh 1 part inside them. Then, it passes through the inner opening 10 and is sent out of the machine.

0012 The above leaf disc filter element for tar pitch filters uses regeneration treatment. To do this, remove the rim 6 and separate the parts 1, 2, and 3. Pitch solids are removed, washed, roasted, etc. After the playback process is finished, the new Using the new rim 6, each of the above parts 1, 2, and 3 is fixed again by the caulking method. It is then provided for reuse.

[0013]

[Effect of the idea]

According to the above leaf disc filter element for tar pitch filter, the filter Remove pitch solids and clean each part, including the router media, as a single unit. Since cleaning can be performed, extremely good removal and cleaning effects can be obtained. roasted again Even in some cases, the excess carbon content has already been removed, so there is no risk of ignition caused by carbon. Good roasting can be performed without ignition.

[0014] As a result of the above, it becomes possible to use it for a long time even if it is reused, and The service life until the entire product is discarded is much longer than before.
