External argon cooling and oil removing system for glove box

Abstract

The invention relates to an external argon cooling and oil removing system for a glove box. The system comprises a glove box used for casting lithium ingots in an argon atmosphere and further comprises a first pipe and a second pipe which are arranged at the two ends of the glove box respectively, and a first cooler, a cyclone oil remover and a second cooler are sequentially connected between the first pipe and the second pipe. The inlet end of the cyclone oil remover is connected with the outlet end of the first cooler, the outlet end of the cyclone oil remover is connected with the inlet end of the second cooler, and the first cooler and the second cooler are both filled with oil removal filter elements. According to the device, oil stains in argon can be effectively removed through the first cooler, the cyclone oil remover and the second cooler, meanwhile, the first cooler and the second cooler can play a role in cooling argon, cooling after metal lithium casting is facilitated, the cyclone oil remover can remove the oil stains in the argon under the centrifugal effect generated by cyclone, and under the effect of cyclone, argon can flow directionally, so that the oil removal efficiency is improved, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a glove box argon external cooling and degreasing system. Background technique [0002] Metal lithium ingots are generally cast in a glove box and cooled in the glove box. Since metal lithium is easy to oxidize, they will be cast under the protection of inert gas in the glove box. [0003] At present, in order to obtain metal lithium with low impurity content and high purity, it is necessary to purify argon gas. However, the current general treatment is to reduce water, oxygen, and nitrogen, and in order to remove oxygen and nitrogen, a specific chemical reaction device needs to be installed. However, in During the lithium metal casting production process, an oil seal is also required to prevent the oxidation of liquid lithium metal. Therefore, the inert protective gas argon often carries oil stains, which are easily polluted and discolored during the cooling process of ...

[0003] At present, in order to obtain metal lithium with low impurity content and high purity, it is necessary to purify argon gas. However, the current general treatment is to reduce water, oxygen, and nitrogen, and in order to remove oxygen and nitrogen, a specific chemical reaction device needs to be installed. However, in During the lithium metal casting production process, an oil seal is also required to prevent the oxidation of liquid lithium metal. Therefore, the inert protective gas argon often carries oil stains, which are easily polluted and discolored during the cooling process of metal lithium. Direct chemical oxidation is used. The product It is very easy to be brought back into the glove box by the inert protective gas, and it is easy to cause secondary pollution to metal lithium
