Problems solved by technology

[0005] At present, among the PSA purification devices that have been practically used, most of them are to cool down the gas to be adsorbed in advance, and the temperature of the adsorbent caused by the heat release during the adsorption process increases, resulting in a smaller adsorption capacity and poor adsorption capacity. The phenomenon of poor effect is lack of corresponding effective measures to control it, so the final effect is not ideal

Abstract

The invention relates to the technical field of gas treatment, and discloses a liquid carbon dioxide spray type pressure-variable temperature-controlled adsorption tower, which includes a tower body, a pressure control subsystem, a spray subsystem and an adsorption subsystem; the adsorption subsystem includes an adsorption bed and an adsorption Bed fixed plate; the adsorption bed is distributed in the tower body at intervals along the vertical direction, and its two ends are fixedly connected with the tower body through the adsorption bed fixed plate; the spray subsystem includes spray main pipe, spray branch pipe and spray pipe; spray main pipe Fixed in the tower body, the spray branch pipes are equally spaced and parallel in the annular area of ​​the spray main pipe. The spray pipes are arranged in the vertical direction, and one end is connected with the spray main pipe or the spray branch pipe. Both chambers are connected to the pressure control subsystem. Its beneficial effects are: while the mixed gas is adsorbed and purified, the temperature of the adsorption bed is lowered, the temperature of the adsorbent is reduced, and the service life of the adsorbent is prolonged. control.

Description

technical field [0001] The invention relates to the technical field of gas treatment, in particular to a liquid carbon dioxide spray type pressure-variable-temperature-controlled adsorption tower. Background technique [0002] Pressure swing adsorption technology is a new gas separation technology that has emerged in the industry in recent years. It mainly uses the difference in the adsorption characteristics of gas components on solid adsorbents and the characteristics of the adsorption capacity changing with pressure, and realizes the separation or separation of gases by changing the pressure. Purification, so the regeneration speed is fast and the energy consumption is low. It is an energy-saving gas separation technology. [0003] The key to pressure swing adsorption is physical adsorption. Physical adsorption is mainly caused by the interaction between adsorbate and adsorbent molecules. There is no chemical reaction in this process. The adsorption process unfolds very ...
