Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to pulverized coal from which fine powder has been removed.

[0002]

[Prior art]

 Fine powder is mixed in pulverized coal or the like obtained by cutting wood into sawdust and firing.

[0003] Pulverized coal and the like have a very large outer surface as compared to a lump of charcoal because they are finer than a lump of charcoal. Therefore, if the inner surface of the porous body is brought into direct contact with air, the adsorbing power can be increased. Although it can be used, it contains fine powder that emits dust and smoke, so it is used in bags made of non-woven fabrics, etc., so its adsorption power is reduced.

[0004]

[Problems to be solved by the invention]

 The problem to be solved is to remove fine powder from pulverized coal etc. to make it easy to handle, but if air is blown directly onto it, it will be scattered and if crushed, it will generate fine powder again Therefore, it can be stored in a container to prevent this, and can blow air directly, making it easy to collect, replace, replenish, and treat charcoal fragments and charcoal particles after adsorbing substances contained in the air. It is to be.

[0005]

[Means for Solving the Problems]

 The purpose of the present invention is to prevent pulverized coal or the like from flowing out to the outside even if air is directly blown on the coal granules and fine charcoal pieces after washing and drying with running water and to prevent them from being crushed. By combining charcoal grains and fine charcoal pieces with filters and containers to form a trinity, air can be blown directly directly, and after adsorption of air content, collection, replacement, replenishment, and disposal Etc. can be easily performed.

[0006]

[Embodiment of the Invention] Washing and drying of pulverized coal and the like and storage of charcoal particles and fine charcoal pieces in filters and containers are realized in a small number of steps.

[0007]

【Example】

 Cedar is one of the softest carbon materials except paulownia, but the Minamimaki-mura Forestry Association in Minamimaki-mura, Hatsura-gun, Gunma Prefecture has commercialized it by cutting and thinning cedar mainly into sawdust and firing and carbonizing it. I have.

In the open air, 200 ml 30 g of trade name deodorized coal was placed in a wire mesh washing container having a wire diameter of 0.18 mm and a mesh of 40 mesh / inch, and tap water was jetted for 15 seconds and washed thoroughly with running water at a distance of 10 cm. .

Due to the wet adhesion caused by containing water, the fine charcoal pieces do not flow away from the sieve eyes due to the close contact with the charcoal pieces or with the coal particles, and the fine powder whose adhesion force has lost the water flow is washed away, and After 5 to 10 seconds, the black water containing the fine powder was absorbed into the soil, and after 10 to 15 seconds, the black water did not flow out.

The weight of the washing container was 140 g, and the total weight of the washing container and the container immediately after washing was 280 g. Thus, the wet coal powder was 140 g.

Half a day after repeating this 10 times, the pulverized coal weighs 70 g per serving, and when the pulverized coal is spread and shaded for 2 hours, the pulverized coal weighs 50 g. Began individualization by drying.

After further drying in the sun for 2 hours, the weight returned to 30 grams, and individual fine pieces of charcoal could be identified.

[0013] No change in weight corresponding to the fine coal powder that flowed out with the black water could be found. The water content is unknown.

When the charcoal particles and fine charcoal pieces for 10 times were collected and bottled, the volume was 1900 ml. The charcoal pieces were not crushed with a light rub.

[0015] A cardboard box 22 cm long and 7 cm wide and 7 cm deep is made. The center of the bottom is cut out with a diameter of 16 cm. The top cover is cut out with a hole having a diameter of 20 cm. A wire mesh having a wire diameter of 0.18 mm and 40 mesh / inch was stuck.

[0016] The two-ply nonwoven fabric is cut into four sides of 34cm, and the center is glued with cardboard that has been punched out into 22cm on four sides, 20cm in inner side, and 1cm in width, stretched and pasted, and laid on the bottom of a cardboard box. Was.

A stainless steel cylinder having a top outer diameter of 21 cm, a bottom outer diameter of 18.5 cm, an inner diameter of 17 cm, and a height of 7 cm was placed on the nonwoven fabric in the box.

A hollow steel disc having an outer diameter of 18 cm, an inner diameter of 16.5 cm, and a width of 0.75 cm has a wire diameter of 0.2 mm. A wire mesh of 1 mm 100 mesh / inch was cut into a diameter of 17.5 cm, attached and pasted, and installed at a height of 1 cm from the bottom of the cylinder.

[0019] 45 ml of 300 ml of charcoal grains and charcoal pieces bottled on a wire mesh in a cylinder were weighed and charged, and the center thickness was adjusted to 1 cm.

An upper lid to which a wire mesh was attached was hung and fixed.

The equipment used above is as follows.

[Table 1]

This adsorption filter is placed between two lightweight blocks, covered with a cylinder having a diameter of 19 cm and a height of 42 cm, and while blowing air from a height of 50 cm with AC 100 V and 45 W, 30 g of flour is spooned in small amounts for 5 minutes. When sprayed, a very small amount adhered to the 40 mesh / inch wire mesh for the inner wall and lid of the cylinder, but all flour was adsorbed by the charcoal pieces and charcoal particles, and although some charcoal pieces became cloudy, most of them remained black was. Twenty grams is 20,000 mg, 20,000,000 μg.

The used charcoal particles and charcoal pieces adsorbing the flour were put into a non-woven fabric laid in a paper box from a cylinder, the upper part was tied up, and discarded together with combustible waste.

The equipment used was as follows.

[Table 2]

[0025] The wire mesh when the powdered coal or the like is washed is a filter, the wire mesh attached to the lid of the container is also a filter, and the bottom wire mesh for preventing runoff and the nonwoven fabric on the bottom are also filters. And charcoal pieces are also filters.

This is an adsorption filter in which the properties of each filter are combined for each purpose, thereby adsorbing fine dust, odors, pollutants and the like in the air as a whole.

[Effect of the invention]

 As described above, the adsorption filter of the present invention does not involve dust and smoke due to fine powder, so it is easy to handle.After use, transfer the used product from the container to a nonwoven underlay to prevent charcoal pieces from spilling. The waste can be treated as it is simply by changing and tying the upper part. In the embodiment, cardboard was used for the outer container.However, by making the outer container made of plastic or steel, it is possible to wash the most contaminated lid wire mesh, and to replace the charcoal grains / charcoal pieces and the underlay for replacement. Repeated and continuous use can be performed simply by preparing the nonwoven fabric.

In FIG. A blower was installed at B, but the thickness of the non-woven fabric was increased and the wind direction was changed. If a suction machine is installed in Hei, the amount of adsorption will increase, and if the wind power is increased by using Otsu and Hei together, the suction power and amount will be several times higher. The weight ratio of fine powder to pulverized coal is negligible, and the one with low weight has a large internal surface per weight, but the total surface area is small if the weight itself is small. Charcoal is essentially fuel, thinned wood in forestry management is industrial waste, and pulverized coal production is the reuse of industrial waste. If air can be blown directly onto the fine coal, etc. from which the fine powder has been removed, it will adsorb the content regardless of the type of substance that can be physically adsorbed without generating dust. Even if it is cigarette smoke, even if it is nitrogen oxides, sulfur dioxide, hydrocarbons, carbon monoxide, suspended particulate matter, diesel vehicle exhaust particulates, dioxins, smoke emissions, unpleasant odor substances, etc. Those that can be adsorbed will be adsorbed to the about without specifying the target. Adsorb pollutants in the air to products that reuse industrial waste, and after adsorbing them, they are primarily fuels, and because they are fine porous bodies, they can burn at high speeds and ensure high temperatures, and are most desirably incinerated. The most remarkable effect of the present invention is that it can be incinerated with the adsorbed material. Ventilation fans are equipment that transfers indoor contaminated air to the outdoors, but the fact that they do not differ qualitatively from the idea of illegal dumping, which transfers unnecessary waste to other places, is an example of unpleasant odors and smoke emission from restaurants, etc. It is not necessary to see. The use of the adsorption filter according to the present invention is significant by installing it at the exhaust port of the ventilation fan, the vertical part of the air duct inside the building, and the like.
