Description

[Detailed description of the invention] This invention is an adsorption device in which an adsorption layer is formed by filling an adsorption column with an adsorbent such as activated carbon, and a fluid to be treated is passed through this adsorption layer to perform deodorization, etc.
This invention relates to an adsorption device that makes effective use of adsorbent and saves labor in replacing it.

Conventionally, there are two types of multilayer adsorption devices: vertical and horizontal types. The vertical type, as shown in FIG. This support member 2 is filled with an adsorbent such as activated carbon to form an adsorption layer 3 in any number of stages, and the support member 2 is covered with exhaust gas, waste water, etc. from the inlet 4 to the outlet 5. The processing fluid is passed through and deodorized by contact with the adsorbent. By the way, since the adsorbent is filled into the adsorption layer 3 through the inlet 6 provided above the adsorption layer 3, it is difficult to level the upper surface of the adsorption layer 3, and the thickness of the adsorption layer 3 in the fluid flow direction (up and down) There are problems such as uneven flow (direction) and drift, and in order to level the top surface, it must be done through the input port 6, which makes the work complicated. In addition, the adsorbent outlet 7
is provided at the bottom of the adsorption layer 3, but the bottom surface of the adsorption layer 3 is also horizontal because it is necessary to make the thickness uniform in the direction of water flow. Bad sex.

In the horizontal type, as shown in FIG. 2, a plurality of adsorption layers 3 are formed by supporting an adsorbent in a sandwiched state by a support member 2 within an adsorption cylinder 1. With this structure, since the discharge port 7 must be shaped like a hopper, the fluid does not come into contact with the adsorbent that has entered the hopper, and that portion becomes a dead space.

With the above points in mind, the purpose of this invention is to stack the cylindrical adsorption layers at an angle, thereby making effective use of the adsorbent and saving labor for replacing it.

This invention will be explained below based on the attached FIG. 3 showing an embodiment thereof.

As shown in the figure, a cylindrical body 10 such as a cylinder or a square cylinder
The upper and lower surfaces of the holder are covered with a breathable member 11 such as a wire mesh, and an adsorbent 12 is filled therein to form an adsorbent layer A, and the plurality of adsorbent layers A are placed between the upper edge of the lower one and the bottom of the upper one. A portion of the edges are connected through a valve, and the layers are stacked one after another by tilting so that the upper and lower surfaces of each layer face each other. Although the embodiment is of a two-layer type, it is of course possible to use two or more layers.

A semi-cylindrical plate 13 closes the periphery of the facing surfaces of adjacent adsorption layers A, so that the fluid that has passed through the lower adsorption layer A flows into the upper adsorption layer A without leaking.

An on-off valve 14 is provided at the connecting portion of the adjoining adsorption layers A, and by opening this valve 14,
The adsorbent 12 in the upper adsorption layer A is transferred to the lower adsorption layer A.
It is possible to fall inside. An adsorbent inlet 15 is formed at the top of the upper surface of the uppermost adsorption layer A, and an adsorbent outlet 16 is formed at the lowermost part of the lowermost adsorption layer A.

In addition, in the figure, 17 is an inlet of the fluid to be treated, 18
is an outlet, and 19 is a support frame of the adsorption device.

The adsorption device of this invention is constructed as described above,
In the adsorption action, the fluid to be treated, such as exhaust gas or waste water, flows in from the inlet 17, passes through the adsorption layer A, and is discharged from the outlet 18, as in the conventional case, and is deodorized by contact with the adsorbent 12. At this time, since the thickness of the adsorption layer A in the fluid flow direction (between the upper and lower surfaces) is constant,
The adsorption action is carried out smoothly without any drifting.

When replacing the adsorbent 12, the valve 1
4 is opened to communicate each adsorption layer A, and the discharge port 16 is opened.
The adsorbent 12 is extracted from the adsorbent, and new adsorbent is supplied to the uppermost adsorption layer A from the input port 15. In other words, since the adsorbent 12 closer to the inlet 17 normally reaches the saturated adsorption amount earlier,
Since the adsorbent 12 near the 7 side is discharged, the adsorbent 12 in the part where the final treatment is performed is always new, making it possible to perform very efficient treatment. At this time, since the discharge port 16 is located at the mouth of the hopper-shaped portion, the adsorbent 12 can be smoothly discharged without needing to be scraped out. In addition, the input port 16
Since the hopper is also located at the top of the inverted hopper-shaped portion, the entire area of the cylindrical body 1 is uniformly filled with the adsorbent 12 by simply introducing the adsorbent 12.

As mentioned above, according to the adsorption device of this invention,
The upper and lower surfaces of the cylindrical body are covered with a permeable material such as a wire mesh, and an adsorbent is filled therein to form an adsorption layer. The upper and lower surfaces of the adsorbent layers are stacked one after another so that they are connected at a portion, and the upper and lower surfaces of the adsorbent layers are stacked one after another so that the edges of the opposing surfaces of the adjacent adsorbent layers are closed. In addition to forming an adsorbent inlet, an adsorbent outlet is formed at the bottom of the lower surface of the lowermost adsorption layer, and an on-off valve is provided in the communication section of the adsorption layer, so that the adsorption in the flow direction of the fluid to be treated is possible. The layer thickness is constant and there is no dead space, so efficient adsorption processing can be performed, and the adsorbent is extremely easy to replace.
