The vacuum powder storage tank is filled with low-temperature liquefied gas (oxygen, nitrogen, argon and the like). The traditional air supply mode adopts a vacuum powder storage tank to supply air through an air supply device of a pressure reducer after passing through a vaporizer. First, the cryogenic liquefied gas in the storage tank is vaporized into a gaseous gas at normal temperature, and the device for converting the cryogenic liquefied gas into the gaseous gas is called a vaporizer. The low-temperature liquefied gas vaporizer generally adopts an air bath vaporizer made of aluminum tilted sheets, which is a technological process for realizing liquid-to-gas conversion by realizing heat exchange between atmosphere and low-temperature liquefied gas, and in the vaporization process, moisture in the air can be condensed and frosted. After the air bath type vaporizer works for a long time, vaporization capacity is gradually reduced, so that temperature is gradually reduced after vaporization, and timing switching is needed.
