JPH0427416A - Honeycomb shaped deodorant filter - Google Patents

Abstract

PURPOSE:To increase air permeating efficiency and cleaning efficiency by allowing porous glass filters to erect and attach to the corrugate working paper and allowing a honeycomb sphaped dry type deodorant body to be impregnated and absorbed into a solution incorporating flavonoid to be a natural deodorant ingredient. CONSTITUTION:The honeycomb shaped deodorant filter is obtained by honeycombed with the corrugated working paper 6 erected and attached substantially with the porous glass fibers to produce dry type deodorant body 1, or impregnate and absorbed dry type body 1 into the aqueous solution of flavonoid being the natural deodorant to produce wet type deodorant body 2. Also, before impregnated into flavonoid solution, the dry deodorant body 1 and the wet deodorant body 2 are laminated to produce conjugated materials 3, 4. When the porous glass fiber 5 reaches a saturated condition, and even if once absorbed bad smell ingredient is desorbed, reabsorption by flavonoid to be the natural deodorant is carried out. The relevant flavonoid has a non-reversible chemical absorption function and high continuous stability without desorption action of odorous components.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a honeycomb deodorizing filter.

(Prior art) Some conventional deodorizing filters include a honeycomb molded body made by attaching porous glass fibers that have excellent adsorption performance for basic malodorous components to corrugated paper. has a physical adsorption ability that releases the adsorbed components when they reach a saturated state, so although they are fast-acting, they lack long-term stability.

(Problems to be Solved by the Invention) In view of the above-mentioned problems, the present invention makes it possible to maintain stable adsorption performance by adsorbing the odor components again even if they are released in a saturated state. The purpose of the present invention is to provide a honeycomb-shaped deodorizing filter.

(Means for Solving the Problems) In order to achieve the above object, the present invention takes the following technical measures.

That is, the first method is to impregnate and absorb a dry deodorizing body 1 made of honeycomb-shaped corrugated paper 6 to which porous glass fibers 5 are substantially erected, and then soaked in an aqueous solution of flavonoids, which are natural deodorizing ingredients. The second method is to use the wet deodorizing material 2 as a dry deodorizing material 2 before impregnating it with flavonoids.
and the wet deodorizing body 2 described in the first means were laminated to form a composite 3°4.

(Function) According to the present invention, a dry deodorizing body 1 made of honeycomb-shaped corrugated paper 6 to which porous glass fibers 5 are attached is impregnated and absorbed into an aqueous solution of flavonoids, which are natural deodorizing ingredients, to moisten the dry deodorizing body 1. Since the deodorizing body 2 is used as a natural deodorizing body 2, even if the porous glass fibers 5 reach a saturated state and release the malodorous components that have been adsorbed, they are re-adsorbed by flavonoids, which are natural deodorizing components. Since the flavonoid has irreversible chemisorption ability, it has no desorption effect and has high sustained stability.

Moreover, when the wet deodorizing body 2 dries, it can be regenerated by immersing it in the flavonoid aqueous solution again and absorbing it.

(Example) Embodiments of the present invention will be described below based on the drawings.

In the drawings, FIGS. 1 to 4 are schematic diagrams showing a honeycomb deodorizing filter.

1 is a dry deodorizing body before being impregnated with flavonoids, and 0.5 g of porous glass fiber 5 is attached to corrugated paper 6.
It is a honeycomb-shaped deodorizing filter with a size of 55 mφ x 20 flTII.

Examples using the dry deodorizing body 1 of this size will be shown below.

Figure 2 shows the dry deodorizing material 1 at a temperature of 25°C at a concentration of 3 to 3.
20wt%, amount 40+nj! A wet deodorizing body 2 is obtained by immersing the flavonoid in an aqueous flavonoid solution and allowing it to stand for one day.

FIG. 3 shows a composite 3 of 2 sheets of wet deodorizing bodies each having a size of 55 mmφ×5 bodies impregnated with an aqueous flavonoid solution under the above conditions and the dry deodorizing body 1 shown in FIG. 1.

FIG. 4 shows a composite 4 in which the dry deodorizer 1 is sandwiched between two wet deodorizers 2 shown in FIG. 3.

In the present invention, porous glass fibers having the following characteristics are particularly used.

Main components: 810□ 96-t% or more Fiber length = 10
μm1~5am Pore diameter: 50 Å or less Specific surface area: 400 pores/g or more Pore volume: 0.4~0.6 cd7g If the above characteristics are not met, the adsorption performance as a filter will drop significantly, so deodorization and purification will be required. Low efficiency and inappropriate.

The dry deodorizing body 1, wet deodorizing body 2, and composite body 3.4 of these used in the present invention are each preferably made of a honeycomb-shaped corrugated paper 6 having the following structure, for example.

That is, as shown in FIG. 5, porous glass fibers 5 are attached on at least one side of seven examples of smooth paperboard of the corrugated paper 6, and porous glass fibers 5 are attached on at least one side of the corrugated paperboard 8 side of the corrugated paper 6. The processed paper 6 with porous glass fibers 5 attached thereto, and the processed paper 6 with porous glass fibers 5 attached on at least one side of the smooth paperboard 7 and the corrugated paperboard 8 have improved air permeation efficiency and purification efficiency. Especially good from the outside.

Moreover, as mentioned above, since the porous glass fibers 5 are substantially attached to the corrugated paper 6 in an upright manner, even when immersed in an aqueous solution of flavonoids, flavonoids are not present in the processed paper 6 itself nor in the small pores of the glass fibers 5. It is also impregnated with water and absorbed efficiently.

Next, the corrugated paper 6 used in the present invention is preferably one that retains its shape even when impregnated with an aqueous solution of flavonoids and has high water content.

More specific examples of the present invention will be described below.

In a certain container (capacity 501), honeycomb deodorizing bodies 1, 2, 3.4 as shown in FIGS. 1 to 4 were installed as an air cleaning model in an atmosphere with an initial ammonia concentration of 200 ppm, The results of an ammonia deodorizing performance test in which the ammonia removal rate was repeatedly measured after 2 hours are shown in the table below.

However, as a target concentration, ammonia concentration was also measured without a deodorizing filter.

(Next leaf) As can be seen from the table above, compared to the comparative example dry deodorizer 1 before impregnation with flavonoids, the wet deodorizers 2 and composites 3 and 4 impregnated with flavonoids (examples) have less ammonia. The removal rate is high, especially wet deodorizing body 2 used alone,
It can be said that the composite 4 in which the dry deodorizing body 1 is sandwiched between two wet deodorizing bodies 2' having a walking length has a deodorizing performance close to 100%.

(Effects of the Invention) In the honeycomb-shaped deodorizing filter of the present invention, the dry deodorizing body 1 has a wet deodorizing body 2, that is, a corrugated paper 6, and porous glass fibers 5 are substantially attached in an upright manner to form a honeycomb shape.
By using a product impregnated and absorbed in an aqueous solution of flavonoids, which are natural deodorizing ingredients, the desorption effect of the porous glass fiber 5 can be sufficiently captured, and it is fast-acting and
It has excellent long-term stability.

Moreover, when the flavonoid-impregnated wet deodorizing bodies 2 and 2' are dried, they can be regenerated by immersing them in the flavonoid aqueous solution again and absorbing them.
