Abstract

The invention relates to an adsorbent compressing device used in a pressure-swing absorber and an adsorbent compressing method thereof, and the invention relates to a molecular sieve compressing device in the pressure-swing absorber and a method thereof. The adsorbent compressing device solves the problem that the current adsorbent compressing devices cannot adjust height of an upper orifice plate so that the upper orifice plate is easily turned on its side, and a structure and an operation process are simple. A lower transverse plane of the upper orifice plate is an arc surface, a first through hole and several second through holes are arranged on the upper orifice plate along axial direction, the first through hole is positioned at a circle center of the upper orifice plate, an upper end of an elastic fixed rod is fixed at a lower end of a cover plate, the lower end of the elastic fixed rod is fixed at the upper transverse plane of the upper orifice plate, the elastic fixed rods are uniformly arranged along the circumference direction of the upper orifice plate, the upper end of a guide bar is fixedly connected to the lower end of an outlet duct, the upper orifice plate is sleeved on the guide bar, and a sealing head is positioned at the lower end of the upper orifice plate and enables threaded connection with the guide bar. The invention provides the adsorbent compressing device used in the pressure-swing absorber and the adsorbent compressing method for compressing the molecular sieve.

Description

technical field [0001] The invention relates to a compacting device and an adsorbent compacting method for an adsorbent in a pressure swing adsorption tower. Background technique [0002] Using straw and biological manure to ferment biogas, the calorific value of the combustion gas is relatively low, which is wasteful. The current method is usually to use the pressure swing adsorption process to separate, purify and recover methane. This process uses the selective absorption of carbon dioxide gas by the adsorbent to separate For methane, the methane recovery rate is relatively high. The problem in the existing method of compacting the adsorbent is that when the adsorption and desorption process steps are used, when the gas pressure is too high, the flow rate is too fast, or the weight of the upper orifice plate is not enough, the adsorption tower The upper orifice plate is pushed by the adsorbent, which will cause the center of the upper orifice plate to deviate, or even rol...
