Abstract

PROBLEM TO BE SOLVED: To simplify a post-treatment process by converting a recovered halogenated hydrocarbon to a decomposed material with a catalyst while suppressing the quantity of the generation of an intermediate product in the decomposition step and fixing the decomposed material by adsorption to efficiently suppress the generation of the intermediate product. SOLUTION: The halogenated hydrocarbon vaporized in a thermal distillation chamber 21 is introduced into a catalytic reaction vessel 31, causes decomposition reaction by contact with an activated catalyst 60 and as a result, is converted to a halide with the removal of hydrocarbon. The hydrocarbon is recovered. Further a hydrogen source 100 is fed to the catalytic reaction vessel 31 through a pipe line 101 with a pump 102 while controlling the flow rate with a flowmater 103 to efficiently convert the intermediate product such as carbon tetrachloride, dioxin to a halide. Next, the halide is transported to an adsorption vessel 41 by a pump 43. An adsorbent 61 is peaked in the adsorption vessel 41 and adsorbs the transported halide. Waste gas after the halide is removed is discharged through a discharge port 44.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an apparatus and a method for treating general waste and industrial waste, and more particularly to an apparatus and a method for treating equipment having an organic halide-containing foamed resin in a structure.

[0002]

2. Description of the Related Art Conventionally, when a waste electrical home appliance is disposed of, it is treated as general waste when discarded by a general consumer, and as industrial waste when disposed of by a business or the like. As described above, although the treatment of the same waste home electric appliances was different depending on the disposal source, the landfill treatment was mainly used in both cases.

Among the above-mentioned waste home appliances, for example, a waste refrigerator uses a foamed polyurethane resin as a heat insulating material. As a foaming agent for the foamed polyurethane resin, for example, monofluorotrichloromethane (hereinafter, CFC-
11) and difluorodichloromethane (hereinafter CFC-
12). As a result, the landfill treatment increases the volume, while the crushing treatment may release organic halides such as CFC-11 and CFC-12.

[0004] Since the discovery of the ozone hole, CFC-11 and CFC-12, which are relatively stable substances, diffuse into the stratosphere without being decomposed when released into the atmosphere. Since it is decomposed by ultraviolet rays and causes destruction of the ozone layer, its use and treatment as specified CFCs are internationally regulated.

[0005] Therefore, in the treatment of waste home electric appliances and the like that may release the specific CFCs into the atmosphere, it is required to dispose of the specific CFCs after decomposing and detoxifying the specific CFCs in advance, rather than simply landfilling. .

[0006] It has been considered to use HCFC-22 or HFC-134a instead of specific CFCs such as CFC-11 and CFC-12, but these CFCs also have an ozone depletion potential of zero. However, it is not necessarily harmless to the depletion of the ozone layer, and it is required to reduce its use in stages. In this way, even for wastes that include the emission of halogenated hydrocarbons, including wastes that use foamed polyurethane resin containing these alternative CFCs as a foaming agent, the alternative CFCs are decomposed and made harmless. Processing is required.

[0007]

However, many intermediate products are generated in the process of decomposing and detoxifying specific CFCs and CFC substitutes. If these intermediate products are stabilized without being decomposed into final decomposed products, there is a problem that even if an attempt is made to decompose or adsorb with a catalyst or an adsorbent, they are discharged to the atmosphere without being adsorbed.

Further, when the decomposition and adsorption of the intermediate product are to be more complete, a separate post-treatment means is required, which causes a problem that the apparatus becomes complicated.

Further, in some cases, if exhaust gas detoxified as a final decomposition product returns to the reaction tank again, there is a problem in that the exhaust gas may come into contact with the catalyst to produce a fluorocarbon compound or the like again. There is.

[0010] The present invention has been made to address such a problem, and is more efficient in the process of decomposing and detoxifying specific CFCs (CFC-based) and alternative CFCs (HCFC-based, HFC-based). It is an object of the present invention to provide a waste disposal apparatus and method capable of suppressing generation of an intermediate product.

And a second step of converting the recovered halogenated hydrocarbon into a decomposed product by a catalyst while reducing the amount of an intermediate product generated in the decomposition process, and adsorbing and immobilizing the decomposed product.

In the waste treatment apparatus of the present invention, equipment having a halogenated hydrocarbon-containing foamed resin as a part of a structural material is, for example, a foamed resin using a halogenated hydrocarbon as a foaming agent, particularly a polyurethane resin. Equipment incorporating a heat insulating material, such as a refrigerator and an air conditioner.

Means for recovering the halogenated hydrocarbon from the equipment include a method of mechanically crushing the equipment and a method of steaming and carbonizing. At the time of carbonization, a temperature adjusting means and a carrier gas introducing means such as a nitrogen gas or a rare gas can be provided.

In the waste treatment apparatus of the present invention, intermediate products generated in the process of decomposing halogenated hydrocarbons do not react with adsorbents other than halides such as hydrochloric acid and hydrofluoric acid adsorbed and fixed on the adsorbent. Refers to a compound. Specific examples include carbon tetrachloride, dioxin, trichlene, dichloromethane and the like.

In order to reduce the amount of such an intermediate product, when decomposing a halogenated hydrocarbon, (a) adding a hydrogen source, and (b) contacting an adsorbent, Generation of products can be suppressed, and a cleaner exhaust gas can be discharged through an adsorption step performed in a later stage. In addition, when a hydrogen source is added and decomposed, and the gas before adsorption flows back into the adsorbent, an intermediate product may be formed again.Therefore, a means for preventing this backflow, for example, a check valve or the like is provided. This is very important.

In the means for adding a hydrogen source, water and a hydrocarbon compound can be used alone or as a mixture as the hydrogen source. By adding the hydrogen source, an intermediate product such as carbon tetrachloride that does not react with the adsorbent becomes hydrochloric acid or hydrofluoric acid. In order to sufficiently react the intermediate product, the temperature of the catalyst is preferably set to 300 ° C. or higher. Further, the amount of hydrogen to be added is preferably larger than the stoichiometric amount sufficient to generate hydrochloric acid or hydrofluoric acid by reacting with the halogenated hydrocarbon. Is preferred. When gasifying a hydrogen source, it is preferable to have means for controlling the temperature to a temperature equal to or higher than the temperature at which the substance vaporizes.

Examples thereof include calcium carbonate and calcium hydroxide.

The calcium-based adsorbent is used in a mixture with a halogenated hydrocarbon decomposition catalyst, but is preferably used in a mixing ratio that allows the catalyst and the adsorbent to have the same life. This is because it is desirable to replace the catalyst with the adsorbent at the same time. The mixing ratio can be determined by measuring the change in the decomposition rate of the halogenated hydrocarbon and the adsorption rate of the halide. In addition, the rate of adsorption with halides is improved by setting the temperature of the adsorbent to 300 ° C. or higher. The mode of mixing may be uniform mixing or lamination.

Embodiment 2 A catalytic reaction tank 31 according to the waste treatment apparatus of the present invention will be described with reference to FIG. FIG. 4 is a diagram showing an outline of a preferable apparatus for adding a hydrogen source. As shown in FIG. 4, a substance containing a hydrogen source passed through a flowmeter 103 through a pump 102 is used to gasify a substance containing a hydrogen source 100 into a pipe 101 between the flowmeter 103 and the catalyst reaction tank 31.

On the other hand, when the catalyst and the adsorbent are mixed and filled in the catalytic reaction tank, the calcium adsorbent, for example, calcium carbonate is nearby as shown in FIG. React
Since free chlorine ions are eliminated, it becomes difficult to generate carbon tetrachloride.

FIG. 8 shows the change in the CFC decomposition rate and the adsorbent adsorption rate over time when the same amount of catalyst and adsorbent are mixed and filled at the volume ratio. In addition, the adsorbent adsorption rate was shown by the hydrogen chloride removal rate. According to FIG. 8, it can be seen that the adsorbent adsorption rate is significantly lower than the reduction of the CFC decomposition rate of the catalyst. On the other hand, in general, when a chemical adsorbent undergoes an adsorption reaction and changes to a completely different substance and becomes stable, the reaction hardly occurs any more, so the amount of adsorbent and the amount of adsorption are proportional. In a relationship. FIG. 9 shows the lapse of time between the amount of the adsorbent and the adsorption rate. It can be seen that when the amount of the adsorbent doubles, the adsorption rate decreases, for example, about twice after 120 minutes. . Therefore, when calcium carbonate is mixed into the catalyst reaction tank, it is understood that it is better to make the amount of the adsorbent larger than the amount of the catalyst, assuming that replacement is performed at the same time.

Embodiment 6 The treatment temperature of the catalyst reaction tank 31 according to the waste treatment apparatus of the present invention will be described with reference to FIGS. 10A and 10B. FIG. 10-a and FIG. 10-b show the change in the adsorption rate of hydrogen chloride depending on the temperature conditions for the calcium-based adsorbents CaCO ₃ and Ca (OH) ₂ . Fig. 10-a
10 and FIG. 10B, it can be seen that the adsorption rate is improved at about 300 ° C. or higher.

FIG. 11 shows a case where the catalyst 60 and the adsorbent 61 are uniformly mixed with each other, and FIG. 12 shows a case where the catalyst 60 and the adsorbent 61 are respectively laminated and mixed. FIG. 11 shows an example in which the catalyst 60 and the adsorbent 61 are arbitrarily mixed. After the decomposition of the chlorofluorocarbon by the catalyst 60, the radicalized halogen immediately comes into contact with the surrounding adsorbent 61 to form a halogen compound. The effect that a product is hardly generated is obtained.

FIG. 12 shows that the catalyst 6
0, adsorbent 61, catalyst 60, and adsorbent 61 are added in this order. However, fluorocarbon is decomposed by the first catalyst 60, and then the radicalized halogen is brought into contact with adsorbent 61 to form a halogen compound to produce intermediate compounds. When the product is generated, it is decomposed again and adsorbed, whereby an effect of preventing the intermediate product from being discharged to the downstream side of the catalytic reaction tank can be obtained.

[0045]

As described above, the waste decomposition apparatus or method of the present invention decomposes halogenated hydrocarbons recovered from equipment having a halogenated hydrocarbon-containing foamed resin as a part of its structural material. Since there is a means or a step of adsorbing and immobilizing the decomposed product while reducing the generated amount of the intermediate product in the process while decomposing the decomposed product by the catalyst, the generated amount of the intermediate product can be largely suppressed.
As a result, the waste decomposition treatment apparatus of the present invention can simplify the post-treatment process for treating an intermediate product.
