JPH07144146A - Device for separating residual gas from gas vessel - Google Patents

Abstract

PURPOSE:To surely separate residual gas to recover a gas by causing gas vessels in which the residual gas is sealed to flow down into noncombustible liquid and crushing the gas vessels in the noncombustible liquid. CONSTITUTION:Gas vessels 3 in which a gas remains are thrown in a hopper 4 and flowed down into a passage of a chute 5, and are pushed by a ratchet 153 with the transfer of a chain belt 121 to flow down into noncombustible liquid 1, and crushed by the engagement of cutting blades of crushing fixtures 191, 192 and broken down into fragments 28. When the gas vessels 3 are crushed, the gas remaining in the vessels is discharged therefrom and flows out into the noncombustible liquid 1 and rises to enter the 1st hood 29. The liquid entrained in the gas is removed by a liquid removing device 32 and the gas alone is sent to a desired place through a vent cylinder 30. The gas blowed out to outside the 1st hood 29 is caught by the 2nd hood 34 and sent to a desired place from vent holes 37, 38. Fragments 28 are sent to outside a casing 2 by a conveyor 26 and stored in a pan 27.

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an apparatus for separating residual gas from a gas container.

[0002]

2. Description of the Related Art When a gas container such as a gas cylinder in which a gas such as a gas is enclosed is discarded as waste, it is required to make a hole in the container and degas it before discarding it.
At that time, before cutting or crushing, using a sharp knife by hand, after making a hole in the container and releasing gas such as gas to the atmosphere, it was cut or crushed by a cutting or crushing device If the gas was not completely removed, there was a risk of fire and explosion due to the residual gas. Further, gas such as gas cannot be collected and is released to the atmosphere, which deteriorates the working environment.

[0003]

In a gas container to be discarded as waste, the degassing is not sufficient and there is a problem. Some local governments select whether or not the recovered gas container is degassed, and the ungassed container is degassed by workers by conventional means, and is ready for recycling. In recent years, due to the problem of global environmental pollution, it has been decided to completely abolish specific CFCs, which are ozone-depleting substances, and highly flammable gas has begun to be used as a substitute for CFCs for general household spray cylinders. Therefore, the work of venting a large amount of gas containers becomes more dangerous (ignition and explosion), and the atmospheric emission of gas is becoming a new pollution and a health problem for workers.

Therefore, the present invention is intended to provide an apparatus for separating residual gas from a gas container capable of ensuring a safe and clean working environment.

[0005]

[0006] Further, a degassing tube for guiding a separated residual gas body provided in contact with the surface of the nonflammable liquid to the predetermined location is provided in the first hood, and an upper surface of the casing is provided above the first hood. A second hood having a gas vent hole to be fixed is fixed, a conveyor unit that conveys the fragments of the gas container to the outside of the housing is provided below the pair of crushing tools, and the chute is formed by a plurality of paths. In addition, a device for separating the residual gas from the gas container is configured so that the gas container is sent by moving the feed claw.

[0007]

The present invention is constructed as described above, and the gas container is flown down by the feed claws in the chute having a plurality of passages, and the gas container is crushed by the pair of crushing tools installed in the noncombustible liquid. The residual gas is separated, the separated gas rises in the incombustible liquid, is captured by the first hood, and is fed to a predetermined place by the gas vent cylinder.
