Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deodorizing element for indoor purification in which the uneven stripes of the folds of the deodorizing element are deeply combed and the adsorption capacity is enhanced.

[Conventional technology]

Recently, deodorizing bags have been used as part of air conditioning equipment to improve the livability of cars and other rooms. It is used as one of the deodorizing elements used in the deodorizing equipment to remove materials such as sheets and lining materials, various paints, smoking materials, and body odor that tend to get trapped indoors. Honeycomb-type activated carbon elements in the form of a lattice or circular hole honeycomb are used because of their ease of handling and low airflow resistance.

[The interlayer point that the invention attempts to solve]

By the way, the above-mentioned deodorizing element is generally made by extruding a raw material of powdered charcoal mixed with an appropriate amount of binder through a die, forming it into a lattice-shaped plate or a honeycomb-shaped plate, and then putting it into a firing activation furnace and heating it at the required temperature and atmosphere. It is made by activating under The problem is that the porosity, which is a characteristic of activated carbon, is reduced, and the contact area with the treated odor is reduced accordingly, making it difficult to obtain a sufficient adsorption effect. It is inconvenient that the 1ζ shape cannot be changed, a set area that is 1ζ larger than the processing capacity is required, and that the size of the ventilation 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, and includes blending pulp and heat-melting fibers as a binder material, forming a strip of activated carbon paper by forming the binder material and activated carbon powder, A large number of concave and convex stripes forming sharp waves in the width direction are provided on the activated carbon paper using a hot roll, and rectangular pleats are continuously formed in the shape of a chrysanthemum using a folding process. Then, slits are provided leaving the pleat ridges, the pleat troughs, and both side edges of Sζ, and a large number of air passages are formed by the uneven stripes of the flat part of each pleat, and end plates are fixed to both ends of the slits.

[Operation] Dirty indoor air flows from the outer periphery of the deodorizing element toward the inside. The activated carbon in the activated carbon paper passes through the flat portions of each adjacent pleat and is removed by the activated carbon in the activated carbon paper as it passes through a large number of air passages formed by sharply uneven stripes. The heat-melting fiber mixed as a binder is melted by a hot roll and holds the activated carbon paper according to the shape of the roll, forming sharp uneven stripes. Furthermore, the melting of the heat-melting fibers strengthens the bond between the pulp and the activated carbon powder, contributing to improving the rigidity of the activated carbon paper.

〔Example〕

The deodorizing element shown in Figure 1 consists of an activated carbon paper 2, an inner cylinder 3, and an end plate 4.
It consists of The inner cylinder 3 is made of a perforated punched iron plate or wire mesh formed into a cylindrical shape, and activated carbon paper 2 is placed around it.
is installed.

The activated carbon paper 2 is in the form of a belt with a thickness of about 0.2 to 1 mm, and is made by blending wood pulp and heat-melting fibers such as polypropylene or polyethylene in an appropriate ratio as a binder material. The binder material and activated carbon powder are made into paper. As shown in detail in FIG. 2, after the required number of grooves 5 and protrusions 6 which are sharply waved in the width direction are formed in the longitudinal direction, peaks 7 and ridges are formed alternately in the longitudinal direction. A rectangular pleat ridge 9 is continuously provided to form a trough 8, and a slit 11 is provided at the fold line between the pleat ridge 7 and the pleat trough 8, leaving both side edges 10. It is being

When arranged around the inner cylinder 3, the wavy grooves 5 of each adjacent pleat 9 are in contact with each other and the convex lines 6 are facing each other, or the convex lines 6 are in contact with each other and the concave lines 5 are facing each other. , a large number of ventilation paths 12 are formed along each pleat ridge 9. The sharp uneven strips 5.6 having one flat part of the pleats 9 are obtained by passing the strip-shaped activated carbon paper through a hot corrugated roll heated to a temperature equal to or higher than the melting point of the hot-melt resin blended as a binder. At this time, the resin melted by heat strongly binds the pulp surrounding it with the activated carbon powder, and is widely dispersed within the activated carbon paper 2, leading to an improvement in paper strength. Also, the activated carbon paper 2 is held in the roll shape.

During use, dirty air in the vehicle interior enters from the entire outer periphery of the deodorizing element 1, and various odors 2 passing through the numerous ventilation channels 12 along the adjacent pleats 9 are adsorbed, deodorized, and returned to the vehicle. Return to the room.

As another example, as shown in FIG. 3, the slits 11 provided on the fold lines of the folded crests 7 and troughs 8 are used as upper and lower surfaces, and the slits 11 are compressed on both sides. If the rectangular plate-shaped end plate 14 is fixed, it can be used as a rectangular deodorizing element 13.

〔Effect of the invention〕

As described above, in the present invention, sharp uneven stripes are formed in the width direction of activated carbon paper made by blending pulp and hot melt resin with activated carbon powder as a binder material using a hot corrugate roll, and the elements are made by pleating. The hot roll spreads the melted resin inside the activated carbon paper 2, which acts as a binder and binds the pulp and activated carbon powder, forming sharp uneven stripes in the width direction, resulting in a large number of concave and convex stripes along the adjacent pleats. By forming the ventilation path, the ventilation resistance can be reduced, and the filling of the adsorbent (activated carbon powder) can be improved, and the contact surface area can be expanded. In addition, the distributed resin improves paper strength and stiffness, making it easier to handle.
