Improved cyclone bin for pentane gasification mixing tank

The utility model discloses an improved cyclone bin for a pentane gasification mixing tank, which comprises a cyclone bin positioned in the middle of the mixing tank, gas mixers are horizontally and fixedly mounted at positions close to the top and the bottom in the cyclone bin, and a cavity positioned in the cyclone bin is arranged between the two groups of gas mixers; a plurality of groups of outer spiral drainage grooves and inner spiral drainage grooves which vertically penetrate through the gas mixer are formed in the gas mixer in the circumferential direction of the gas mixer at equal intervals. According to the gas mixer, the outer spiral drainage groove and the inner spiral drainage groove are spirally formed in the gas mixer, the flowing airflow directions in the outer spiral drainage groove and the inner spiral drainage groove are opposite, cyclones in opposite directions can be formed in the cavity, gases with the opposite cyclones collide with each other, pentane is further dispersed in the collid
