Multi-group adsorption equipment for purifying impure helium

The utility model belongs to the field of helium purification, particularly relates to multi-group adsorption equipment for purifying impure helium, and provides the following scheme aiming at the problems that the existing equipment for purifying impure helium is poor in purification effect, cannot remove some particulate matters contained in helium, and is low in purification efficiency and inconvenient to use. The device comprises a gas storage tank, a first adsorption tank and a second adsorption tank, the left side of the first adsorption tank is fixedly connected with a gas suction pump, the input end of the gas suction pump is fixedly connected with a gas inlet pipe, and one end of the gas inlet pipe is fixedly connected with the top of the gas storage tank. Particle impurities and harmful substances in impure helium can be filtered and adsorbed through a filter screen and an activated carbon screen plate, subsequent purification is facilitated, the purification time can be shortened through a cooling
