Cooling separation device type helium purification equipment

The utility model discloses cooling separation device type helium purification equipment which comprises a breather pipe, a primary condensation pipe shell and a secondary condensation pipe shell are sequentially and fixedly connected to the peripheral side face of the breather pipe, and a dehydration molecular sieve and sulfur-soaked activated carbon are connected to the interior of the end, close to the primary condensation pipe shell, of the breather pipe in a clamped mode. One end of a first guide pipe penetrates through the bottom of the part, located in the primary condensation pipe shell, of the ventilation pipe, the other end of the first guide pipe penetrates through the bottom of the primary condensation pipe shell, and one end of a second guide pipe penetrates through the bottom of the part, located in the secondary condensation pipe shell, of the ventilation pipe. According to the helium purification device, the primary condensation pipe shell, the secondary condensation pipe shell, the hydrogen s
