Abstract

PURPOSE:To enhance adsorbing efficiency, by forming water passing fine gaps between adsorbent particles by heat-meltable fiber chips between which adsorbent particles are mutually interposed before melting and solidifying said chips. CONSTITUTION:An adsorbing plate material 1 is prepared by a method wherein number less adsorbent particles comprising activated carbon or activated clay are mutually interposed between numberless heat meltable fiber chips which are, in turn, melted and solidified in a porous state to form water passing fine gas between adsorbent particles. A desired number of through-holes 2 are provided to the adsorbing plate material 1 and plural numbers of the adsorbing plate materials 1 are laminated so as to mutually communicate corresponding through- holes 2 thereof to constitute a laminated adsorbing plate 3. Furthermore, by mutually communicating the corresponding through-holes 2 of the adsorbing plate materials 1, water passing channels 6 each having a large diameter part 4 and a small diameter part 5 are formed to the laminated adsorbing plate 3 at plural places.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an adsorbent for water purification that is made of adsorbent particles as a base material and is used for adsorbing and removing impurities in water or an aqueous solution.

(Prior art) Conventionally, when removing trace amounts of chlorine ions and other faint odor substances contained in water using activated carbon or activated clay,
Particles of activated carbon or activated clay are passed through an adsorbent layer on which they are deposited and adsorbed, but when using such an adsorbent, special care must be taken in handling to maintain the adsorbent layer in a stable state. For this reason, activated carbon particles and activated clay particles are sometimes solidified by binding them with a binder, but when they are solidified, the activated carbon particles and activated clay particles inevitably become too dense compared to when they are filtered as a sediment layer. , the filtration resistance of the liquid that permeates through the solid body becomes large.

(Objective of the Invention) The present invention solves the above-mentioned problems, solidifies adsorbent particles such as activated carbon and activated clay, makes handling easier, and has a large adsorption capacity and low filtration resistance. It was developed for the purpose of being an efficient adsorbent for water purification.

(Structure of the Invention) The present invention uses heat-fusible fiber chips in which numerous adsorbent particles are interposed between each other to form slits for water passage between each adsorbent particle to fuse and assimilate the particles, and to form the required amount on the plate surface. In a laminated adsorption material made of a plurality of adsorption plates each having a number of through holes, a passageway having a plurality of large diameter portions and small diameter portions is formed by communicating the corresponding through holes of each adsorption plate material. The present invention will now be described in detail with reference to the illustrated embodiments.

(1) In this method, countless adsorbent particles such as activated carbon or activated clay are fused and assimilated into a porous form with countless thermofusible fiber chips interposed between each other to create slits for water passage between each adsorbent particle. The suction plate material (1) is a hard suction plate material with a required number of through holes (2) provided therein.

In addition, the adsorption plate material shown in the figure (1 N is a composite fiber having a polypropylene fiber as a core and a polyethylene film with a lower melting point formed on the circumferential surface thereof, is cut into pieces of about 1 to lon+n+, and is made up of countless thermofusible fiber chips and adsorbent particles. The weight ratio is l:9
Mix well in a mold so that the ratio is about 1:15 to 1:15, and heat-melt fiber chips are interposed between each adsorbent particle, and at least the surface of the heat-melt fiber chips is melted while being slightly compressed. After being heated to a certain degree, it is cooled and fused and assimilated to form a hard porous adsorption plate material with a packing density of 0.4 to 0.7 g/cc. Then, a plurality of these suction plates (1) are stacked with the corresponding through holes (2) of each suction plate (1) communicating with each other, and the laminated suction plate (3) is stacked.
), but the corresponding through hole (2) of each suction plate material (1)
) By making the comrades communicate with each other, a water passage (
6), each through hole (2) has a large diameter part 14) and a small diameter part (5), as shown in FIGS. 1, 2, and 4. Either the suction plate material (1) has a truncated conical cross section, or the suction plate material (1) has a small diameter through hole (2) and the suction plate material (1) has a large diameter through hole (2) as shown in Fig. 3.
1) are arranged alternately during stacking, with the large-diameter through-hole (2) serving as the large-diameter portion (4), and the small-diameter through-hole (2) forming the large-diameter portion (4).
2) portion may be used as the small diameter portion (5). Furthermore, even when using a laminated suction plate (3) provided with a through hole (2) having a truncated conical cross section and a large diameter part (4) and a small diameter part (5), the first implementation shown in FIG. As shown in the example, the large diameter part (4) of the through hole (2) can be used as a conduit (6) in a continuous abacus manner, as in the second embodiment shown in Fig. 2. It can also be used as a water passageway (6) in which the small diameter part (5) continues to the large diameter part (4) so as to be located in the center of the large diameter part (4), or as a fourth embodiment shown in FIG. The water passage (6) may be formed by eccentrically connecting the small diameter part (5) to the large diameter part (4) as shown in FIG.
and a small diameter portion (5), the retention time of the fluid sent from one end of the passageway (6) to the other end is increased, and the adsorption performance is enhanced.

With this structure, adsorbent particles such as activated carbon or activated clay are fused with heat-fusible plastic fiber chips to form a solidified product that is easy to handle. It is extremely easy to handle compared to other adsorbent particles, and since the pores for water passage are located between the adsorbent particles, a sufficient adsorption area is ensured for contact with water or impurities in the liquid that permeates through the pores for water passage. Moreover, since the through-holes (2) of each adsorption plate material (11) form a communication channel (6), the filtration resistance does not become excessive. (4) has a small diameter part (5), and has a structure in which the cross-sectional area of the flow path changes or is bent according to the communication direction, so the water or liquid flowing in the flow path (6) is A turbulent flow as conceptually shown is generated, which increases the residence time of the fluid and creates favorable conditions for it to permeate through the laminated adsorbent material (3), greatly increasing the adsorption effect. It becomes.

(Effects of the Invention) As is clear from the above description, the present invention solidifies countless adsorbent particles without deteriorating adsorption performance, making it easy to handle and having multiple large diameter parts and small diameter parts. Since the passageway is formed using a laminated adsorbent material, the filtration resistance is small and the adsorption efficiency is extremely high.Also, by laminating adsorption plates with the required number of holes, the passageway can have multiple large diameter parts. Since the small diameter part is formed, it has the advantage that it is easy to manufacture and can be provided at low cost, and it will greatly contribute to the development of the industry as it solves the problems of conventional adsorption moons for water purification.
