Technical Field
The invention relates to the technical field of graphite falling film absorbers, in particular to an intelligent graphite falling film absorber.
Background
The graphite falling film absorber is a falling film type gas absorption device mainly made of impermeable graphite. By impervious graphite is meant a graphite article that is impervious to fluid media such as gases, vapors, liquids, and the like. The graphite material is a special non-metallic material, not only has good physical and mechanical properties and processability, but also has excellent corrosion resistance and high thermal conductivity, so that the graphite material is an ideal material for manufacturing chemical anti-corrosion equipment. The graphite product as a structural material also contains some high molecular materials or other components to adapt to different use conditions.
The graphite falling film absorber consists of three parts, including gas-liquid distributor comprising gas and liquid inlet pipes, pressure stabilizing ring, liquid distributing pipe and other impervious graphite parts, absorbing and cooling section and gas-liquid separator. Graphite falling film absorbers are essentially in which the heat extracted and concurrent downward flow of the two gas absorbed and liquid absorbed streams is effected by a shell and tube heat exchanger circulating cooling water within the shell.
