Description
Technical Field
The invention belongs to the technical field of carbon dioxide concentration devices, and particularly relates to a zeolite cylinder type rotating wheel for carbon dioxide concentration.
Background
At present, the greenhouse gas CO2Emission reduction is a big problem in air pollution control, which draws great attention of the international society. Wherein the adsorption process is the recovery of CO2The gas is usually used. At present, a PSA (Pressure Swing Adsorption) method is mainly adopted in an Adsorption method, but the system has large occupied area, high system resistance and higher requirement on Pressure resistance of related equipment.
If a single fixed adsorbent bed is used for operation, either temperature swing adsorption or pressure swing adsorption, the adsorption is intermittent due to the need for regeneration of the adsorbent. PSA pressure swing adsorption systems are typically loaded with granular activated carbon or silica gel, which has a relatively high resistance. Wherein, for the pressure swing adsorption cycle process, there are three main working steps: adsorption under pressure, decompression desorption and pressure increase. During the adsorption under pressure, the adsorption bed is introduced with the separated gas mixture under the highest pressure in the working process, wherein the strong adsorption component is selectively absorbed by the adsorbent, and the weak adsorption component flows out from the other end of the adsorption bed. During decompression desorption, several methods of decompression, vacuum pumping, flushing and replacement are selected according to the performance of the adsorbed component to regenerate the adsorbent. During pressure raising, decompression desorption is performed, the pressure is reduced to atmospheric pressure, flushing, vacuumizing or replacement is performed, after the regeneration of the adsorbent is completed, the adsorption bed is pressurized by the weak adsorption component until the adsorption pressure is reached, and then adsorption is performed under the pressure. FIG. 1 shows the change in adsorption loading of an adsorbent versus pressure during a pressure swing cycle. Therefore, when the pressure swing adsorption cycle is adopted, two or more adsorption beds are adopted industrially, so that the adsorption and regeneration of the adsorption beds are alternately (or sequentially) performed, and the continuity of the whole adsorption process is ensured, but the problems of complex system, large equipment floor area and the like are caused.
