Problems solved by technology

[0003] During the welding process, excess argon gas containing impurities will be discharged into the air, which will not only cause waste of argon gas, but also cause pollution to the environment because these impurities are mostly dust, carbon monoxide, carbon dioxide, etc.

Embodiment 1

[0017] Such as figure 1 As shown, an argon gas recovery method for argon arc welding includes the following steps: (a) Collection: Recover argon gas during welding. The argon gas is filtered and buffered and stored. When argon gas is recovered, a suction hood is used Cover the welding machine, collect the argon gas during electric welding, and connect it to the buffer tank through a pipe equipped with a fan; (b) Impurity removal: absorb and remove the impurity gas and smoke in the argon gas, and remove the argon in the buffer tank. The gas is sent to the absorption tower and the argon purifier in turn, the packing in the absorption tower is 13x molecular sieve, and the argon passing through the absorption tower is purified by the argon purifier; (c) storage: the purified argon is pressurized to 0.3 -0.5MPa and store.

Abstract

The invention discloses an argon arc welding argon recovery method and an argon recovery apparatus thereof, and relates to the field of gas recovery. The recovery method comprises the steps of collection, impurity removal and storage. The recovery apparatus sequentially comprises a suspended hood fan, a buffering tank, an absorption tower, an argon purifier and a storage tank from front to back, all parts are connected through a pipeline, and a packing in the absorption tower is 13x molecular sieve. The apparatus adopting the method utilizes a filter device to remove dusts in argon, and utilizes the absorption tower and the argon purifier to remove impurity gases in the recovered argon, so the purity of argon in the storage tank is guaranteed.

Description

Technical field [0001] The invention relates to the field of gas recovery, in particular to an argon recovery method for argon arc welding and an argon recovery device. Background technique [0002] Argon arc welding is a welding technology that uses argon as a shielding gas. During the welding process, argon prevents the welding material from contacting oxygen in the air, and prevents the welding material from oxidizing. [0003] During the welding process, excess argon containing impurities will be discharged into the air, which will not only cause waste of argon, but also cause pollution to the environment because these impurities are mostly dust, carbon monoxide, carbon dioxide, etc. Therefore, it is necessary to purify and recover the discharged argon. Summary of the invention [0004] In order to solve the above-mentioned shortcomings of the prior art, the present invention provides an argon recovery method for argon arc welding and an argon recovery device. The method and th...
