Abstract

(57) [Summary] [Purpose] To provide a device for safely and reliably recovering cheaply used phylon gas by using used service cans. [Structure] A motor 20, a compressor 18, a high-pressure hose 17, etc. are used to send the chlorofluorocarbon collected in a fan condenser 15 installed at the upper part to produce liquefied chlorofluorocarbon gas, which is made to flow into a transparent storage container 4 and an inflow opening / closing valve 6 and a decompression opening / closing valve. 14 and container internal pressure meter 7 and discharge on-off valve 5
By attaching the base valve 2 to the used service can 1 and making the reused service can 3 and putting liquefied CFC gas in it for reuse, and collecting the CFC gas released for decompression, there is no waste. And

Description

[Detailed description of the device]

[Field of Industrial Application] The present invention is an apparatus for preparing the reused by entering the recovered CFC gas into a used service can in a liquefied state.

[Prior Art] Conventionally, there have been various recovery and reuse devices for CFC gas recovery devices or recovery devices, but all of them are expensive and cannot be easily cleaned inside the storage container, etc. I had thrown away his service can.

[Problems to be Solved by the Invention] [0003] This invention is intended to develop a reuse device cheaply, easily and safely.

[Means for Solving the Problems] Now, with reference to the drawings, (a) a screw valve 2 having an inside valve 11 installed inside a service can valve screw portion 10 of a used service can 1 It is well known that a packing 12 is attached to the screw part 10 and a paint lock is applied to the screw part 10 to further perform a pressure test and a leak test. Finally, a vacuum is drawn and the reused service can 3 make. (B) The discharge opening / closing valve 5 is attached to the lower part of the transparent storage container 4, and the reuse service can 3 is connected to the lower part thereof. As is well known, it is more effective if the filter 13 is installed inside. (C) A liquefied chlorofluorocarbon gas inflow opening / closing valve 6 is attached to the upper part, and a lid 8 having an inflow passage leading to the inside of the storage container 4, a vessel internal pressure meter 7 and a pressure reducing passage communicating with the vessel internal pressure reducing opening / closing valve 14 is formed by a band 9. . As is well known, a fan condenser 15, a high-pressure meter 16, and a high-pressure hose 17 are connected to the upper part of the liquefied chlorofluorocarbon gas inflow opening / closing valve 6 to form a compressor 18 and a chlorofluorocarbon recovery hose 19, and 20 is a compressor. It is a motor that moves. Further, the container internal pressure reducing / opening valve 14 is connected to a device for recovering specific CFC gas named as the invention of Japanese Patent Application No. 5-610509 or a recovery device found in Japanese Patent Application No. 5-12987 so that it is not released into the atmosphere. is there.

[Operation] With the above configuration, when the compressor 20 is operated by the motor 20 and the recovered CFC gas is sent to the fan condenser 15, it becomes liquefied in the fan condenser and the liquefied CFC gas inflow valve 6 is opened, and the storage container 4 is opened. It is well known that the container internal pressure reducing valve 14 and the discharge on-off valve 5 are closed at this time, and the liquefied CFC gas inflow valve 6 is closed because the liquefied CFC gas accumulated in the storage container 4 has a high pressure. Open the container internal pressure reducing valve 14 and release it into the specified CFC gas recovery tool 21.22 etc. to reuse the internal pressure of the storage container to the allowable pressure of the service can and close the pressure reducing valve 14 and attach it to the lower part of the transparent storage container 4. Open the discharge on-off valve 5 and put it in the reuse service can connected below it to prepare for reuse of CFCs. Can be obtained.

[Effect of consideration] Therefore, it is possible to reuse the used service can, and to secure the work safety by depressurizing, and it is useless because the CFC gas released at the time of depressurizing is recovered. It is possible to put liquefied fluorocarbon gas into the reuse service can 3 reliably while watching

1. When a plurality of (a), (b) and (c) devices are arranged and used, continuous operation is possible. As described above, CFCs can be easily and cheaply and safely recovered and reused, which has the effect of preserving the global environment.
