Abstract

The invention discloses a pressure swing adsorption apparatus, which comprises: a first adsorption and desorption member communicated to a gas source and a first gas discharge system; a first pressurization machine communicated to the first adsorption and desorption member; a first gas detection device communicated to the first pressurization machine; a second adsorption and desorption member communicated to the first gas detection device and a second gas discharge system; a second pressurization machine communicated to the second adsorption and desorption member; a second gas detection devicecommunicated to the second pressurization machine; and a gas storage tank communicated to the second gas detection device. According to the present invention, with the pressure swing adsorption apparatus, the water contents in the process gas at different parts can be simultaneously detected, the important significance is provided for the timely and accurate positioning of the leakage point, andthe leakage point can be timely found so as to prolong the service life of the pressure swing adsorption apparatus.

Description

technical field [0001] The invention belongs to the field of pressure swing adsorption gas separation and purification, and in particular relates to a pressure swing adsorption device capable of monitoring the water-carrying problem in the pressure swing adsorption process. Background technique [0002] PSA gas separation and purification technology has become a production process and an independent unit operation process in the large chemical industry. Since the pressure swing adsorption relies on the change of pressure to realize the regeneration of the adsorbent, the regeneration speed is fast and the energy consumption is low, which belongs to the energy-saving gas separation technology. However, at present, there is a common problem in large-scale pressure swing adsorption devices, which is the pulverization of the adsorbent. One important reason is that the leakage of the heat exchanger or the fluctuation of the raw gas cannot be detected in time, which leads to the l...
