Совершенствование конструкции насадочных аппаратов за счет равномерного распределения газового потока

Abstract

The modern technical level of solving the problem of efficient operation of adsorbers due to the uniform distri-bution of gas inside the apparatus is considered in detail and ways to improve the adsorbers are proposed. The disadvantages of modern designs of adsorbers and the areas of their use are noted. A brief critical analysis of the designs of devices for uniform loading of adsorbent is given. Based on the analysis and experimental studies, the design of the apparatus has been developed, which ensures a uniform distribution of gas flows inside the apparatus. The objective of the experimental studies was to evaluate the characteristics of the developed design of the apparatus for gas adsorption from gas mixtures. Simplicity of dense uniform loading of adsorbent, increase of process efficiency, low hydraulic resistance of the device are provided. To solve these tasks, an experimental setup has been developed to study the efficiency of the adsorption process using the example of adsorption silica gel of water vapor from a mixture with air. It has been experimentally confirmed that the device has competitive advantages. The design provides a tightly packed adsorbent layer, without voids, which means that the uniformity of the load layer in terms of wear and moisture is ensured. In the design of the adsorber, the possibility of entrainment of adsorbent particles during reverse purging is excluded. The design allows you to flexibly change the performance. The total cross-sectional area of the adsorbent increases in proportion to the vertically number of adsorption baskets. An increase in the number of cycles of the adsorption process will entail an increase in the adsorption capacity of the adsorbent. The design of the device helps to reduce energy consumption, reduce capital costs and increase the productivity of the adsorption plant. The introduction of the adsorber into the technology will ensure reliable operation, energy efficiency and high quality of the process.
