1. radial bed container comprises:

  • Cylindrical substantially shell of tank, said shell has vertical longitudinal axis, loam cake and lower cover;

    The outer basket of cylindrical substantially porous, said outer basket is arranged in the said shell along said longitudinal axis with one heart, and is attached at least one in said loam cake and the lower cover;

    Basket in the cylindrical substantially porous, said in basket along said longitudinal axis is arranged on said porous with one heart outside basket in, and be attached to the loam cake of said container and at least one in the lower cover;

    In the form of a ring outer tunnel substantially, said outer tunnel along said longitudinal axis be arranged on said shell of tank and outside between the basket, and have and can carry the cross section flow area of supplying with fluid or product fluid;

    Cylindrical substantially internal channel, said internal channel is arranged in the said interior basket along said longitudinal axis, and has the cross section flow area that can carry supply fluid or product fluid;

    In the form of a ring bed substantially, said bed is made up of one deck active material at least, the said active material of one deck at least be arranged on said in basket with said outer basket between annulus in;

    Wherein;

    Carry the cross section flow area of said passage of said supply fluid proportional with the mass velocity of said supply fluid, and proportionality constant is more than or equal to 0.7 and smaller or equal to 1.4 with the ratio of the mass velocity of said product fluid with the ratio of the cross section flow area of the said passage of carrying said product fluid;

    AndSaid cyclic bed has bed height and bed transmission length, and said bed height is confirmed as with the bed transmission length and made under the technological work condition of the fluid that is adopted, and the pressure on the length of said internal channel and outer tunnel changes each smaller or equal to 10% of bed pressure drop.
