Liquid mouth connects annular groove；The graphite cover plate covered on graphite cylinder is additionally provided with feed zone, the company of offering on the graphite cover plate
The air inlet of the inner chamber of logical graphite cylinder.
The utility model sets the outlet of annular groove upward, and absorbing liquid, can be along ring after inlet enters annular groove
Shape groove is distributed, and is overflowed to after absorbing liquid is full of annular groove from the top end face of inner cylinder in graphite cylinder, due to absorbing liquid edge
The top end face of inner cylinder is overflowed in hybrid chamber, and absorbing liquid can be uniformly distributed in hybrid chamber, then into graphite block
In material hole.In the utility model, the top end face of inner cylinder is also arranged to triangular-notch weir, triangular-notch weir can make absorbing liquid more equal
Overflow to evenly in hybrid chamber.
Further, the top end face of the inner cylinder is less than the top end face of outer barrel, and the graphite cover plate is resisted against the top of outer barrel
On face.This is designed to ensure that the top end face of inner cylinder has the liquid film of certain altitude, ensures that absorbing liquid can be evenly into mixed
Close intracavitary.
Further, overflow pipe, the inner chamber connection material hole of overflow pipe are provided with the upper surface of graphite block.Overflow pipe is set
Putting can ensure that the intracavity bottom of graphite cylinder has certain liquid storage amount, to ensure the time of contact of gas and liquid, improve gas
The efficiency of liquid mixing.
The utility model can be such that absorbing liquid is circumferentially uniformly distributed along inwall, improve the uniform cloth liquid effect of overflow pipe, increase
The falling film absorption ability of addition platform equipment；Absorption area is also add simultaneously, turn avoid wound of the high-temperature gas to graphite cylinder
Evil, protects graphite cylinder.
