Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a purifying dryer mainly used in a laboratory or the like, and relates to a purifying dryer which vaporizes and cleans samples such as chemicals and dioxin adhered to glass containers and ceramics by high-temperature drying.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as a dryer for drying chemicals attached to a glass container or the like, a dryer that stores a container or the like in a refrigerator and dries with warm air circulating in the refrigerator has been used. At this time, by heating the hot air to a temperature of about 100 ° C to 250 ° C with a heater, it is possible to dry even hard-to-dry chemicals.

[0003]

[Problems to be solved by the invention]

 However, in this type of conventional dryer, the chemicals once vaporized become fine particles and are circulated in the refrigerator together with the warm air because they are dried by warm air circulating in the refrigerator. Therefore, when the dried container is taken out, the fine particles may adhere to the container again.

On the other hand, a container used for a device for measuring a sample such as dioxin needs to be completely cleaned because even small particles affect the measured value. However, this type of conventional drying apparatus was not suitable for high-precision cleaning because it was not possible to control the vaporized fine particles from the container as described above.

[0005] In addition, when chemicals and samples attached to containers and the like are toxic, such as dioxin, even a small amount of fine particles can be discharged from the chamber due to environmental problems. Not preferred.

Accordingly, the present invention has been devised to solve the above-mentioned problem, and it is possible to completely clean a container to which a chemical or the like is attached, and to reliably remove vaporized fine particles removed from the container or the like. The purpose of the present invention is to provide a purifying type dryer that can be collected in the air.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a first means of the present invention is a purifying dryer for blowing heated drying air P2 into the storage 10, and an air supply system purifier 20 for purifying the supply air P1; The air purified by the air supply system purifier 20 is heated to convert it into drying air P2, and the drying air P2 is blown into the storage 10; An exhaust fan 11 for discharging P2 and vaporized fine particles out of the refrigerator and an exhaust cleaner 40 for cooling the discharged air and purifying it again are provided.

[0008] The air purifier 20 of the second means is provided with a polyurethane filter 21, an activated carbon filter 23 and an ULPA filter 24, and the exhaust purifier 40 is provided with an activated carbon filter 42 and a HEPA filter. That is, the filter 43 is provided.

The heating blower 30 of the third means has a meandering air supply pipe 31 disposed above the heater 32, and sets the temperature in the refrigerator to 100 ° C. to 500 ° C.

A fourth means is to mount a water-cooled hot air cooler 41 on the exhaust system purifier 40 as means for solving the problem.

[0011]

[Embodiment of the invention]

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

FIG. 1 is a schematic view of a purification type dryer of the present invention, wherein reference numeral 10 denotes a storage, 20 denotes an air supply system purifier, 30 denotes a heating blower, and 40 denotes an exhaust system purifier.

The storage 10 is provided with an exhaust fan 11 and a heating blower 30 inside. The storage 10 stores glass containers, pottery, other appliances, and the like, and is heated by the heating blower 30. The dried air P2 is blown into the storage to dry the containers and equipment. The illustrated storage 10 has a shelf 12 provided therein.

The air supply system cleaner 20 is a device that purifies the outside air supplied to the storage 10 in advance. In the air supply system cleaner 20, a polyurethane filter 21 is arranged on the outside air intake side, and the air purified by the polyurethane filter 21 is further purified by the activated carbon filter 23 and the ULPA filter 24. In the illustrated example of the air supply system cleaner 20, a supply pump 22 is interposed between a polyurethane filter 21 and an activated carbon filter 23. According to this air supply system cleaner 20, clean air (U.S. Fed. Std. 209E class 100 or less) that has passed through a 0.1 μm ULPA filter 24 is supplied into the storage 10.

The heating blower 30 is a device that heats the air purified by the air supply system cleaner 20 to convert the air into drying air P 2, and blows the drying air P 2 into the storage 10. The heating blower 30 has a meandering air supply pipe 31 disposed above a heater 32. According to such an air supply pipe 31, it is possible to blow the drying air P2 sufficiently heated in a short time into the storage 10. Further, the heating blower 30 can set the temperature in the storage 10 from 100 ° C. to 500 ° C.

The heated drying air P2 dries the containers and instruments in the storage 10 and vaporizes attached chemicals and test samples such as dioxin. Further, the vaporized chemicals, test samples, and the like are forcibly discharged to the exhaust system cleaner 40 together with the drying air P2 by the exhaust fan 11 provided in the storage 10.

The exhaust system purifier 40 is a device that once cools the drying air P2 and the vaporized fine particles in the storage 10 with a cooler, and purifies the air again. The exhaust system purifier 40 is provided with an activated carbon filter 42 and a HEPA filter 43. According to the exhaust system purifier 40, the exhaust air P3 that has passed through the 0.3 μm HEPA filter 43 is discharged from the exhaust system purifier 40. At this time, by using the water-cooled hot-air cooler 41 as the cooler, the drying air P2 heated to 100 ° C. to 500 ° C. can be cooled in a short time.

[0018]

[Effect of the invention]

 The present invention has achieved its original purpose by being configured as described above.

That is, the air supply system purifier 20 for purifying the supply air P 1, and the air purified by the air supply system purifier 20 is heated and converted into the drying air P 2, and the drying air P 2 A heating blower 30 for blowing air into the refrigerator 10 and an exhaust system purifier 40 for cooling the drying air P2 and the vaporized fine particles in the refrigerator 10 and purifying the vaporized particles again to provide chemicals and the like. The container can now be dried and completely cleaned.

Further, since the air supply system cleaner 20 is provided with the polyurethane filter 21, the activated carbon filter 23 and the ULPA filter 24, the container in the storage 10 is not affected by the dirt of the outside air. Since only the deposits adhering to the equipment and instruments can be vaporized, there is no danger of secondary contamination due to the introduction of outside air.

Moreover, since the activated carbon filter 42 and the HEPA filter 43 are provided in the exhaust system purifier 40, the vaporized fine particles can be reliably collected and prevented from being discharged to the outside air.

Furthermore, a heating blower 30 having a meandering air supply pipe 31 disposed above the heater 32 is provided, and the temperature in the refrigerator is set to 100 ° C. to 500 ° C., so that the supply air P 1 for the outside air temperature is reduced. Since the temperature of the drying air P2 can be heated in a short time, the time required for cleaning can be shortened.

Then, the drying air P2 heated to a high temperature can be cooled in a short time by the water-cooled hot air cooler 41 mounted on the exhaust system purifier 40, and the processing time of the dryer of the present invention is reduced. It became possible to do.

As described above, according to the present invention, it is possible to completely clean the container to which the chemicals and the like are attached, and also to surely collect the vaporized fine particles removed from the container and the like, and further treat the particles. There are various practically useful effects such as a reduction in time.
