Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a deodorizing filter that processes malodorous components in malodorous gases using microorganisms or enzymes that perform a 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 by stacking a plurality of corrugated cardboard sheets such that the small through holes formed by the insert paperboard and the liner paperboard 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 the cassette body is placed in the foul-smelling air passage.

The foul-smelling air collides with the cardboard laminate in the flow path, disperses into the through holes, and comes into contact with the walls of the holes, where it comes into contact with the microorganisms that perform the deodorizing action and is deodorized.

[The problem that the idea aims to solve]

In order to impregnate or adhere to such a cardboard filter a bacterial enzyme solution that performs a deodorizing action or a solution consisting of an enzyme solution and a bacterial solution and place it in the odor air path, the cardboard filter is preliminarily coated with a bacterial solution that performs a deodorizing action, etc. In some cases, a cardboard filter is impregnated with or adhered to and then placed in a deodorizing device to allow foul-smelling air to pass through. In other cases, a cardboard filter is placed in a deodorizing device and then impregnated with or adhered to by means such as spraying with a bacterial solution that has a deodorizing effect. It is conceivable that the odor may be attached and the foul-smelling air may be allowed to pass through.

However, in the former case, the weight of the cardboard filter increases due to impregnation or adhesion with bacterial fluid, which impairs workability when installed in a deodorizing device, and the cardboard structure is destroyed when handling wet cardboard. There is also a risk of causing Furthermore, if a wet cardboard filter impregnated with or attached with bacterial fluid or the like is dried by natural drying or artificial drying, the filter becomes relatively easy to handle, but it takes time and effort.

On the other hand, in the latter case, although it is very easy to install the cardboard filter in the deodorizing device, there is a problem in that it takes time to spray or sprinkle water to impregnate the filter with bacterial liquid or the like.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a deodorizing filter that allows microorganisms or enzymes that perform a deodorizing action to be easily attached to a cardboard filter and is easy to handle.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention uses a cardboard deodorizing filter in which a large number of cardboard boxes are stacked so that small through holes open upward and downward, and microorganisms or enzymes that perform the deodorizing action are attached to the cardboard deodorizing filter. Dry microorganisms or enzymes and embed them in a water-soluble substance to form an enclosure.
The gist is that this enclosure is inserted into a small through hole of a filter.

[Effect]

According to the present invention, a cardboard filter with an envelope set therein is disposed in a deodorizing device, and water is sprayed from the top of the filter. When water hits the cardboard filter, the cardboard becomes wet and the enclosure is also supplied with moisture from the damp cardboard. Since the outer material constituting the envelope is water-soluble, it is dissolved by the action of water, and the microorganisms and the like contained within are released. The released microorganisms adhere to the walls of the through-holes of the damp cardboard and are activated by the supply of moisture. Some microorganisms and the like flow out of the deodorizing filter due to sprayed or sprinkled water, but by spraying or sprinkling the water that has flowed out again, it is possible to attach the microorganisms or enzymes that perform the deodorizing effect.

〔Example〕

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

FIG. 1 is a perspective view showing one embodiment of the deodorizing filter of the present invention, and numeral 1 in the figure is a cardboard laminate.

As shown in FIG. 2, the corrugated board laminate 1 is made by laminating a large number of corrugated boards such that the through holes 2a formed by the core paperboard 3 and the liner paperboard 4 of the corrugated boards 2 are all aligned in the same vertical direction. It is made into a block shape. 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.

On the other hand, the bottom material 6 is made of a flat plate with holes in a mesh or lattice shape formed using the same material as the cylinder frame 5, as well as a plurality of rods or pipes arranged in parallel or in a lattice shape. Lay it down and attach it to the cylinder frame 5.
It may be held at the bottom of the .

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

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.

The corrugated board laminate 1 is inserted into the cylinder frame 5 from the upper opening and stored. The side surface of the corrugated board laminate 1 that does not have the small through hole 2a is joined to the inner wall surface of the cylinder frame 5, and the bottom surface is connected to the bottom material. Supported by 6.

In the figure, 7 is an enclosure formed by concentrating a solution of microorganisms or enzymes that perform a deodorizing action, and then drying it by low-temperature drying or freeze-drying to form a powder, and embedding it in a substance 8 that dissolves in water. The size of the enclosure 7 is such that it can be inserted into the small through hole 2a of the cardboard 2.

For example, A with a corrugated board height of about 4.8 mm.
When inserting into the small through hole 2a of the corrugated board 2 called a flute, the cross-sectional diameter of the enclosure 7 is approximately 4.5 mm, and the height of the steps of the corrugated board 2 is approximately 2.5 mm.
When inserted into a corrugated board called a flute, the cross-sectional diameter of the envelope 7 is about 2.2 mm, and for a so-called C flute with a step height of about 3.7 mm, the cross-sectional diameter of the envelope 7 is about 3.4 mm. , step height is 1.2mm
The so-called "E flute" has a cross-sectional diameter of the enclosure 7 of about 1 mm. Here, if the enclosure body 7 has a large diameter, it may be a capsule-shaped container for the water-soluble substance 8, and a powder such as a microorganism may be embedded in this container.

Suitable materials for the water-soluble substance 8 include starch, agar, gelatin, polysaccharide, and the like.

On the other hand, the microorganisms that carry out the deodorizing action are those selected from cellulose-degrading bacteria, filamentous bacteria, sulfur bacteria, air nitrogen-fixing bacteria, rhizobia, sulfur bacteria, actinomycetes, yeast, and pseudomonas bacteria. Plural microorganisms may be mixed if necessary.

The enclosure 7 in which microorganisms or enzymes are embedded is inserted into the through holes 2a of the cardboard 2 constituting the laminate 1 as a filter. The insertion amount is
An enclosure 7 is inserted and installed at a rate of one for every 100 small through-holes, and the stacked body 1 of the cardboard 2 is housed in the cylindrical frame 5 to serve as a deodorizing filter.

To install the enclosure 7, place the corrugated cardboard laminate 1 into the cylinder frame 5.
This can be done either before or after storage.

The deodorizing filter of the present invention is disposed in the malodor air path of the deodorizing device so that the small through holes 2a face the direction of air flow, and water is sprayed by a water sprinkling device provided within the device.

When water is applied to the cardboard filter, the cardboard 2 becomes wet, and the water-dissolved substance 8 that embeds powdered microorganisms etc. is also splashed with water, and water is supplied from the damp cardboard. .

When moisture is supplied to the substance 8, the substance 8 dissolves in the water, and the microorganisms contained therein are released and adhere to the walls of the through holes 2a of the damp cardboard 2.

Microorganisms and the like are activated by the supply of moisture, and the foul-smelling air collides with the cardboard laminate 1 through the bottom material 6 in the flow path, disperses and enters the through-holes 2a, and the As a result of coming into contact with the wall of the hole 2a, it comes into contact with the microorganisms that perform the deodorizing action and is deodorized.

Some microorganisms may flow out of the deodorizing filter by spraying or sprinkling water, but by spraying or sprinkling the flowed water again, the microorganisms that flowed out can be attached.

Since the side surface of the corrugated board laminate 1 without the small through holes 2a is firmly restrained by the cylindrical frame 5, the stacked corrugated boards 2 will not be peeled off or deformed.

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 pulling it out from the cylinder frame 5 and burning it or composting it.
