Description
Technical Field
[0001] This invention discloses a feeding system, particularly a highly efficient and environmentally friendly dense-phase feeding system, which fills a container with two or more layers of adsorbent. It is widely used in various industrial devices such as pressure swing adsorption (PSA), temperature swing adsorption (TSA), and the loading and unloading of various solid catalysts. Background Technology
[0002] The dense-phase feeding / unloading technology of catalysts or adsorbents is widely used in reaction units or raw material refining units in many fields such as petrochemicals, coal chemicals, chemicals, metallurgy, pharmaceuticals, and food, and has become a development area in the skid-mounted field.
[0003] Currently, catalyst or adsorbent loading schemes suffer from low automation, loose loading density, and poor loading effect, making it difficult to guarantee the performance or service life of catalysts or adsorbents. Since catalysts and adsorbents have limited lifespans, they typically need to be replaced every 3-5 years. Due to the influence of on-site equipment density and explosion-proof requirements, efficient loading and unloading operations have always been a starting point for continuous breakthroughs in the industry.
[0004] Dense phase feeding technology is continuously evolving towards high efficiency and energy saving, complete sets of equipment, advanced control, and integrated skid-mounted systems. Verification of the filling density of dense phase feeders is the core technological foundation for this entire innovation, providing direct data support for achieving full automation, eliminating the need for cranes and manpower, and continuously advancing integrated skid-mounted systems. This provides new technical ideas and directions for the systematization, integration, and engineering development of research results, promoting technological progress and industrial development in the dense phase feeding industry and related fields.
