Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a deodorizing element for indoor cleaning, in which the uneven lines of the folds of the deodorizing element are deepened to enhance the adsorption capacity.

[Prior Art] Recently, a deodorizing device is installed as a part of air conditioning equipment to improve the habitability in the interior of automobiles and the like, and the material odors such as seats and linings that tend to get stuck in the interior and various paints It is designed to remove odor, smoking odor, body odor, etc. As one of the deodorizing elements used in the deodorizing device, it is easy to handle and has a small airflow resistance. Therefore, a lattice type or circular hole honeycomb type activated carbon element is used. Is used.

[Problems to be solved by the invention]

By the way, the deodorizing element is generally extruded from a die by mixing a powdered coal with an appropriate amount of a binder, and molded into a lattice-shaped plate or a honeycomb-shaped plate, which is placed in a firing activation furnace at a required temperature and atmosphere. Originally activated, it has the advantage that it is easier to use than granular or lumpy ones, but on the one side, when extruding through a die, the inner surface of each lattice hole or honeycomb hole is smooth As a result, the porosity characteristic of activated carbon is reduced, the contact area with the treated odor is reduced, and a sufficient adsorption effect cannot be obtained. It cannot be changed, requires a large set area for the processing capacity, and has the inconvenience that the size of the vent hole cannot be reduced below a certain level (the contact area cannot be increased).

[Means for solving problems]

The present invention provides a deodorizing element that eliminates such drawbacks, a binder material is prepared by blending pulp and hot-melt fibers, and the binder material and activated carbon powder are formed into paper to form a belt-shaped activated carbon paper, A large number of corrugated strips that are corrugated in the width direction are provided on the activated carbon paper with a heat roll, and rectangular folds are formed continuously by pleating. Then, slits are provided in the fold ridges and the fold valleys so that both side edges are left, and a large number of ventilation passages are formed by the uneven strips of the flat portion of each fold ridge, and end plates are fixed to both ends thereof.

[Action]

The dirty air in the room flows from the outer circumference of the deodorizing element toward the inside. The odor is removed by the activated carbon in the activated carbon paper when passing through a large number of air passages formed by the sharp uneven lines provided in the flat portion of each adjacent fold mountain. The hot-melt fibers mixed as a binder are melted by a hot roll to hold the activated carbon paper in a roll shape and form a sharp uneven line. In addition, the melting of the hot-melt fiber strengthens the bond between the pulp and the activated carbon powder and contributes to the improvement of the rigidity of the activated carbon paper.

〔Example〕

The deodorizing element in FIG. 1 is activated carbon paper 2, inner cylinder 3 and end plate 4.
It consists of and. The inner cylinder 3 is formed by forming a punched iron plate or a wire mesh having a porous shape into a cylindrical shape, and the activated carbon paper 2 is provided around the inner cylinder 3.
Is provided. The activated carbon paper 2 has a band shape with a thickness of about 0.2 mm to 1 mm. The activated carbon paper 2 is made by mixing wood pulp and hot-melt fibers such as polypropylene or polyethylene in an appropriate ratio to form a binder material. It is manufactured by paper-making the binder material and activated carbon powder. Then, as shown in detail in FIG. 2, after a required number of recessed ridges 5 and ridges 6 sharply corrugated in the width direction are formed in the longitudinal direction, mountain portions 7 are alternately formed in the longitudinal direction. Ridge ridges 9 which are fold-folded into a rectangular shape are continuously provided so as to form the valleys 8. Further, slits 11 are provided on the fold lines of the fold ridges 7 and the fold valleys 8 leaving both side edges 10 left. Has been.

When arranged around the inner cylinder 3, the corrugated recesses 5 of the adjacent folds 9 contact each other and the protrusions 6 face each other, or the protrusions 6 contact each other and the recesses 5 face each other. , A number of ventilation paths 12 are formed along each fold mountain 9. The sharp concavo-convex stripes 5 and 6 provided on the flat portion of the fold ridge 9 are obtained by passing the strip-shaped activated carbon paper through a hot corrugated roll having a melting point of the hot-melt resin blended as a binder or higher. At this time, the resin melted by heat strongly binds the pulp around it with the activated carbon powder, and is widely dispersed in the activated carbon paper 2 to improve the paper strength. Further, the activated carbon paper 2 is held in a roll shape.

When the vehicle is used, dirty air enters from the entire outer periphery of the deodorizing element 1, and when passing through a large number of air passages 12 along each adjacent fold mountain 9, various odors are adsorbed and deodorized, and then the vehicle is restarted. Return to the room.

As another embodiment, as shown in FIG. 3, slits 11 provided on the fold line of the fold folds 7 and the fold troughs 8 which are fold-folded.
By using the upper and lower surfaces as the upper and lower surfaces and compressing the folds 9 and fixing the end plates 14 in the shape of a square plate to both side surfaces thereof, it can be used as a square deodorizing element 13.

〔The invention's effect〕

As described above, the present invention is provided with the corrugated rolls in the widthwise direction of the activated carbon powder and the activated carbon paper which has been made by blending the pulp and the hot-melting resin as the binder material, and the corrugated rolls are formed into the elements by the pleating process. The molten resin is widely distributed in the activated carbon paper by the rolls, and it serves as a binder to combine the pulp and activated carbon powder to form uneven lines in the width direction, and by forming a number of ventilation channels along the adjacent fold ridges. The ventilation resistance can be reduced, and the filling of the adsorbent (activated carbon powder) can be improved to expand the contact surface area. Further, the distributed resin improves paper strength and rigidity, which facilitates handling.
