Acetylene gas cylinder acetone supplementing device

Abstract

The invention relates to an acetylene gas cylinder acetone supplementing device, and belongs to the technical field of gas production and split charging. By aiming at the problem that the acetone supplementing of the existing acetylene gas cylinder is not precise enough, the invention provides the acetylene gas cylinder acetone supplementing device, which can realize precise filling. The acetylenegas cylinder acetone supplementing device comprises a nitrogen gas cylinder, an acetone raw material tank, an acetone supplementing tank, a weighbridge and a controller, wherein the nitrogen gas cylinder is respectively connected with a first gas inlet of the acetone raw material tank and a second gas inlet of the acetone supplementing tank; an acetone outlet of the acetone raw material tank is connected with an acetone inlet of the acetone supplementing tank through a hose; an supplementing outlet extends to the bottom of the acetone raw material tank through a pipeline; an acetone filling opening is formed in the acetone supplementing tank; the acetone filling opening extends to the bottom of the acetylene supplementing tank through a pipeline; the acetone filling opening is connected with the gas cylinder through a hose; an electromagnetic valve is arranged between the acetone filling opening and the gas cylinder; the weighbridge is arranged at the bottom of the gas cylinder and isconnected with the controller; the controller is connected with the electromagnetic valve.

Description

Technical field [0001] The invention belongs to the technical field of gas production and packaging, and specifically relates to an acetone supplementing device for an acetylene gas cylinder. Background technique [0002] The storage of acetylene gas is different from other gases. Acetylene is stored in acetylene gas cylinders by dissolving acetone, and the inside of the acetylene gas cylinder is also provided with filler made of calcium silicate; in the repeated use of acetylene gas cylinders, the consumption of acetone is the It is inevitable that too little acetone will directly reduce the amount of dissolved acetylene, making the cylinder unable to fully utilize; however, the amount of acetone should not be too large. Too much acetone will either cause too much dissolved acetylene and increase the pressure, which will not meet the requirements. Before each filling of acetylene, it is necessary to ensure that the amount of acetone inside the bottle is appropriate. Summary of ...

[0002] The storage of acetylene gas is different from other gases. Acetylene is dissolved in acetone and stored in the acetylene gas cylinder, and the interior of the acetylene gas cylinder is also equipped with calcium silicate filler; in the repeated use of the acetylene gas cylinder, the consumption of acetone is at the Inevitably, too little acetone will directly reduce the amount of dissolved acetylene, making the steel cylinder unable to be fully utilized; but the amount of acetone should not be too large, too large will cause too much dissolved acetylene, increase the air pressure, and cannot meet the requirements, so Before each filling of acetylene, it is a necessary step to ensure that the amount of acetone inside the bottle is appropriate
