Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a deodorizing filter used to treat malodorous components in malodorous gases by using microorganisms or enzymes that perform deodorizing action.

[Conventional technology]

Human waste treatment plants, sewage treatment plants, waste treatment plants, slaughterhouses, food factories, fish iliac treatment plants, pig farms, poultry farms,
Odors are a problem in pulp manufacturing plants.

Such malodorous components generally include ammonia, hydrogen sulfide, methyl sulfide, mercaptan,
The main component is amines, and all of them contain nitrogen atoms as in ammonia and amines, and sulfur atoms as in hydrogen sulfide, methyl sulfide, and mercaptans.

Conventionally, combustion methods, activated carbon adsorption methods, cleaning methods, etc. have been known as deodorization methods to remove these malodorous components, but in recent years, biological deodorization methods using microorganisms have become popular due to their low running costs, etc. It has attracted attention because of its advantages, and the development of such devices is progressing.

For example, Japanese Patent Application Laid-open No. 62-221354 proposes impregnating a paper filter with a large number of through holes with a microbial solution that has a deodorizing effect, and disposing this filter as a cassette in a foul-smelling air flow path. has been done.

The cassette body is made into a block shape by stacking a plurality of corrugated cardboards such that the through holes formed in the inner board and the liner board are all aligned in the same direction, and this block-shaped paper filter The cassette body is impregnated with or adhered to a bacterial enzyme solution or a solution consisting of an enzyme solution and a bacterial solution that performs a deodorizing action, and is placed in the foul-smelling air passage.

[The problem that the idea aims to solve]

However, when the filter made of cardboard shown in JP-A No. 62-221354 is exposed to high humidity or high moisture content, the laminated cardboard will swell, become soft, and the adhesive portions will adhere. This causes a decrease in strength, resulting in deformation such as peeling or bending, and in severe cases, the cardboard loses its shape.
There is a risk that it will no longer function as a filter.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a deodorizing filter that can maintain the shape of cardboard well and provide effective gas-liquid contact for a long period of time.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a deodorizing filter made of cardboard to which microorganisms or enzymes that perform a deodorizing effect are attached or impregnated. This is housed in a cylindrical frame equipped with a bottom material made of a rod-like body, a net-like body, or a lattice-like body, and a bar member is removably hung over the upper opening of the cylindrical frame, and the lower part of the cylindrical frame is A means of transportation may also be provided.

[Effect]

According to the present invention, the cardboard housed in the cylindrical frame is supported by the bottom material so as not to impede the air permeability of the through holes, and its side surfaces are restrained by the cylindrical frame. Further, a bar member is hung over the upper opening of the cylinder frame, and even if the cardboard swells due to moisture and an expansion force acts on the cylinder frame, the cylinder frame can be prevented from expanding.

Further, the deodorizing filter made of stacked cardboard boxes and housed in the cylinder frame is taken in and out of the deodorizing device together with the cylinder frame. Can be moved easily.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing a first embodiment of the deodorizing filter of the present invention, and FIG. 2 is a perspective view of the same. In the figure, 1 is a cardboard laminate.

The corrugated board laminate 1 is made into a block shape by laminating a large number of corrugated boards such that the small through holes 2a formed by the core paperboard 3 and the liner paperboard 4 of the corrugated boards are all aligned in the same direction up and down. be. In addition, these blocks may be stacked vertically in multiple layers.

In the figure, reference numeral 5 denotes a cylindrical frame that has approximately the same shape as the corrugated board laminate 1 and is slightly longer in the front-rear direction, and has open upper and lower surfaces. A breathable bottom material 6 made of a rod-like body, a net-like body, or a lattice-like body is attached to the bottom opening of the cylinder frame 5.

The material used for the cylinder frame 5 may be a synthetic resin such as polypropylene resin, polyethylene resin, or acrylic resin, or one or more materials made of metal such as stainless steel or a compound thereof.

Although it may be integrally molded as a cylindrical body from such a material, as another embodiment, as shown in FIG. 4, the side plates may be connected by screws 7 or the like so that the whole can be folded.

On the other hand, the bottom material 6 is a flat plate with holes in a mesh or lattice shape formed using the same material as the cylinder frame 5, and a plurality of rod-shaped bodies or pipes laid in parallel or in a lattice shape. This may be held at the lower part of the cylinder frame 5.

The bottom material 6 can be held on the cylinder frame 5 by bending the lowermost end of the cylinder frame 5 inward into an L-shape to form a flange 5a and supporting the bottom material 6, as shown in the figure; , by fixing the bottom material 6 to the cylinder frame 5 by adhesive, welding, screwing, etc.

It is important to increase the aperture ratio of the bottom material 6 so that the gas can disperse and enter all the small through holes 2a of the cardboard 2 housed in the cylinder frame 5.

A bolt through hole 8 is formed in the upper left and right sides of the cylinder frame 5, and a bolt 9 serving as a bar member is inserted into the through hole 8 and detachably hung from the upper surface opening, and a nut 10 is provided at the outer end. Screw together.

FIG. 2 shows a state in which the corrugated bolt laminate 1 is housed in such a cylindrical frame 5.
The side surface without the small through hole 2a is joined to the inner wall surface of the cylinder frame 5, and the lower surface is supported by the bottom material 6.

The cardboard laminate 1 is attached or impregnated with microorganisms or an enzyme solution that performs a deodorizing effect, and the method for attaching or impregnating the microorganism solution is to directly use a solution obtained by culturing microorganisms in a liquid medium, or to use a culture method in which microorganisms are cultured in a fixed medium. Dissolve the substance in water and impregnate it by spraying or dipping.

Microorganisms that carry out the deodorizing action include those selected from cellulose-degrading bacteria, filamentous bacteria, sulfur bacteria, atmospheric nitrogen-fixing bacteria, rhizobia, sulfur bacteria, streptobacteria, yeast, and pseudomonas bacteria. Depending on the situation, a plurality of microorganisms may be mixed.

Then, the deodorizing filter of the present invention, in which the corrugated cardboard laminate 1 is housed in the cylinder frame 5, is arranged in the malodorous air passage of the deodorizing device so that the small through holes 2a face the air flow direction, and the malodorous air is passed through.

At this time, the foul-smelling air collides with the stage pump stack 1 through the bottom material 6 in the flow path, disperses and enters the through hole 2a, and comes into contact with the wall of the hole 2a.
Here, it comes into contact with microorganisms that have a deodorizing effect and is deodorized.

Since the side surface of the corrugated board laminate 1 without the small through holes 2a is firmly restrained by the cylinder frame 5, the laminated cardboard 2 will not be peeled off or deformed. The bolts 9 can prevent deformation of the cylinder frame 5.

Since the expansion of laminated cardboard due to moisture occurs largely in the stacking direction, it is desirable to align the direction of the bar members with the stacking direction of the cardboard, as shown in Figures 1 and 2. Doing so also prevents the cardboard from slipping out upwards.

On the other hand, the used cardboard laminate 1 is attached to the cylinder frame 5
After taking it out from the deodorizing device, it can be easily disposed of by removing the bolt 9 and extracting it from the cylinder frame 5 and burning it or composting it.

3a and 3b show another embodiment of how to attach the bar member provided on the upper part of the cylinder frame 5, in which a through hole 11 is formed at the upper left and right sides of the cylinder frame 5, and the side of the through hole 11 is A locking portion consisting of a narrow diameter horizontally elongated cut groove 12 is provided. On the other hand, a cylindrical metal rod 13 is used as the bar member, and both ends of the metal rod 13 are partially formed to be thin so that they can fit into the cut grooves 12. Further, a notch 16 is formed on the outer peripheral edge of the cut groove 12 so that both ends of the metal rod 13 do not protrude from the side surface of the cylinder frame 5. When installing the metal rod 13, the metal rod 1
3 through the through hole 11, and the thinly formed portion is inserted into the cut groove 12 and locked.

Furthermore, as another embodiment, as shown in FIG. 5, rotating members 14 such as casters, rollers, bearings, etc.
can also be provided at the lower end of the cylinder frame 5 as a moving means. In addition, such means of transportation are shown in Figures 6 and 7.
As shown in the figure, a slide member 15 such as a long rail may be used. The example in FIG. 6 uses a U-shaped rail, and the example in FIG. This is the case.

By providing such a moving means, the cylinder frame 5 can be smoothly moved in and out of the deodorizing device 16.

On the other hand, by forming uneven surfaces (not shown) on the upper and lower ends of the deodorizing filter of the present invention and making the uneven surfaces fit together so that they can be stacked, the single deodorizing filter can be made smaller. , it is extremely easy to handle.

〔Effect of the invention〕

As described above, the deodorizing filter of the present invention is a deodorizing filter made of cardboard that is attached or impregnated with microorganisms or enzymes that perform a deodorizing effect. Even if a large number of layers are used, the shape of the cardboard can be maintained well.
As a result, effective gas-liquid contact can be obtained for a long period of time even in high humidity conditions or high water content conditions, and deodorizing performance is improved. According to the second aspect of the present invention, the filter can be handled very easily.
