Description

[Detailed description of the invention] A filter tube made by sintering fine particles such as alumina, which has high heat resistance and chemical resistance, can be used as a device for removing particles contained in a fluid, or as a ceramic filter tube filled with quicklime. It can be used in a heat source device, etc. that utilizes the heat of reaction between quicklime and water by injecting water. Due to its low strength, it is usually installed in a device in a cantilevered state using sealing means such as a gasket, but with such a configuration, the efficiency of the fluid flowing through the device is low. It is difficult to provide a high flow of water, and the packing used for supporting the filter tube also has problems such as aging and elution of components.
The high heat resistance and chemical resistance of the sintered ceramic filter tube cannot be fully utilized.

The purpose of this invention is to provide a separation and reaction device that takes full advantage of the unique properties of the sintered ceramic filter tube (hereinafter simply referred to as filter tube) and prevents excessive stress from being applied to the filter tube. The purpose of this proposal is as follows, and the main purpose of the proposal can be explained with reference to figures.

In the figure, 1 and 2 are filter tubes of equal length, 3 is a curved glass tube connecting the lower ends 1a and 2a of the filter tubes 1 and 2, and 4 and 5 are the filter tubes 1 and 2.
It is a straight glass tube connected to the upper ends 1b, 2b of 2. Filter pipes 1 and 2, bent pipe 3, and straight pipes 4 and 5
constitutes a U-shaped tube 6 in which one filter tube is connected to each parallel portion.

7 is a container made of the same material as the glass portion of the U-shaped tube 6;
is placed inside this vessel 7 and is suspended and supported by the top 8 of the vessel 7. The cross-sectional shape of the vessel body 7 is generally circular as shown in the figure, but it may be made into another shape, for example, an oval shape, if necessary. Numerals 9 and 10 are fluid inlet and outlet portions provided on the vessel body 7, and 11 is a fluid outlet connected to a drain pipe or the like.

The container body 7 can be provided with a portion that guides the flow of fluid between the filter tubes 1 and 2. Third
The figures and FIG. 4 show a case in which this guidance is performed by a diaphragm 12.

The direction of fluid flow through the walls of the filter tubes 1, 2 is the direction in which the fluid flows into the filter tubes 1, 2 or the direction in which the fluid flows out from the filter tubes 1, 2, but if the device is used as a separator, In this case, the flow direction is selected so that the fluid to be separated flows from the U-shaped tube 6 into the container body 7.

The equipment used for the separation or reaction is cleaned by backwashing using a suitable medium and made ready for the next use.

The device according to the present invention described above has a high space utilization rate and is designed to prevent excessive stress from being applied to the filter tube. Excessive stress is not applied to the filter tubes 1 and 2 because the amount of horizontal expansion and contraction that occurs at the top 8 of the vessel body 7 is equal to the amount of horizontal expansion and contraction that occurs at the bent tube 3 of the U-shaped tube 6. This is because the following conditions are satisfied, and the condition that the expansion and contraction occurring in the U-shaped tube 6 occurs in the vertical direction without any deviation between the two legs.
