Description

[Detailed description of the invention] The invention is an adsorption block used for gas purification. Specifically, the invention is an adsorption block used for gas purification. Or a rectangular box shape in which a plurality of sheets are stacked and fixed at intervals to form a suction paper, a pair of opposing side portions are open, and the other peripheral portion is sealed with a wall. The present invention relates to a suction block in which a large number of sheets of the suction paper are stacked in a hard case.

In this type of suction block, when the suction paper is stacked vertically, its own weight places a large load on the suction paper at the bottom of the stack, which is compressively deformed and is likely to close the gap. The paper was layered with absorbent paper in the direction.

When adsorbent papers are stacked horizontally in this way, changes in temperature and humidity caused by the supply of adsorption gas or desorption gas to these blocks cause the adsorption papers to expand and contract in the length direction (vertical direction), causing them to buckle. As a result, a gap was likely to be formed between the laminated adsorbent paper and the case wall. Recently, in order to improve gas permeability within the absorbent paper, this absorbent paper has been formed using soft paper, and the laminated absorbent paper is greatly deformed. This has led to the drawback that the adsorption/desorption efficiency is significantly deteriorated.

The object of the present invention is to eliminate such drawbacks and to prevent the above-mentioned drawbacks from occurring due to deformation of the absorbent paper even though absorbent paper is used.

In order to achieve this purpose, the adsorption block of the present invention uses two or more sheets of paper made of a mixture of a powdery or fibrous adsorbent material and another fibrous material with a space between them. The top and bottom of this case are fixed in a box-shaped hard case with a pair of opposing side parts open and the other peripheral part sealed with a wall. A large number of sheets of the absorbent paper are stacked in the stacking direction, and a thickness equivalent to about one to several sheets of the absorbent paper is elastically compressed in the stacking direction, so that the stacking direction is compressed by about 5%. This configuration adopts a structure in which the number of stacked sheets is divided vertically.

With this configuration, there is no risk of the suction paper deforming as it bends, and by dividing the sheets into sections as described above and stacking them up and down, the spacing between the suction papers at the bottom can be significantly reduced. There is no risk of a large compressive load being applied, and since it is compressed in the stacking direction, even if the stacked adsorbent paper expands and contracts in the vertical direction (which is practically slight), the top wall of the case and the stacked There is no longer any risk of creating a large gap between the top surface of the absorbent paper and the top surface of the absorbent paper.

Next, embodiments of the present invention will be described.

FIG. 1 shows the entire adsorption device, in which a filter 2 for adsorbing mist and an adsorption body 4 are provided in a sealed enclosure 1. The suction body 4 has a large number of suction blocks 3 arranged in a cylindrical shape, and is rotated in a fixed direction by a motor 13 around an axis A in the vertical direction. Reference numeral 5 denotes a part for supplying gas to be adsorbed into the sealed enclosure 1, which is connected to, for example, an exhaust port of a painting booth (not shown) via a duct. Reference numeral 6 denotes an outlet section for adsorbed gas, which is supplied from the supply section 5 into the chamber 1;
The gas that has passed through the filter 2 and then the adsorbent 4 to remove the adsorbed substances is discharged to the outside of the chamber 1, for example, into the adsorption port of the painting booth (not shown). They are connected via a duct. 7 and 7' are desorption ducts, which are disposed at predetermined positions in the rotating circumferential direction of the adsorbent 4 so as to face each other on the inside and outside in the radial direction;
The inner duct 7 is supplied with heated gas for desorption (approximately 120°C) from a predetermined heating device (not shown), and the outer duct 7' is supplied with heated gas for desorption (approximately 120°C) from the inner duct 7, which passes through the adsorbent 4 and is supplied to the outer duct 7'. A duct is connected to guide the desorption gas that has reached the duct 7' to a predetermined recovery device or combustion treatment device (not shown).

Next, the adsorption block 3 will be explained in detail. (See Figures 2 and 3) The adsorption block 3 has side surfaces facing each other in the radial direction of the adsorption body 4 open, and the other sides sealed with a wall made of thin iron plate (galvanized).

It is about 2.4m/m. When bonding these two sheets of paper 12, 12' together, the obstruction of ventilation of the sheets of paper 12, 12' by the adhesive is minimized at points along the wavy peaks of the first sheet of paper 12.
