Energy gradient utilization type hydrogen thermal compression system

Abstract

The invention relates to an energy gradient utilization type hydrogen thermal compression system. The system comprises 1-100 stages of hydrogen thermal compressors located in different working temperature intervals and a high-pressure hydrogen total pipe, wherein the hydrogen thermal compressors are provided with low-pressure hydrogen inlets, high-pressure hydrogen outlets and 1-100 metal hydride reaction beds; the low-pressure hydrogen inlets are connected with a low-pressure hydrogen pipeline, and the high-pressure hydrogen outlets are connected with the high-pressure hydrogen total pipe through a high-pressure hydrogen pipeline; an external heat source sequentially passes through multiple stages of the hydrogen thermal compressors through an external heating pipeline from the high working temperature interval to the low working temperature interval; and an interstage heat exchange pipeline is arranged between each two adjacent hydrogen thermal compressors, and an inner-stage heat exchange pipeline is arranged in each stage of the hydrogen thermal compressor. According to the energy gradient utilization type hydrogen thermal compression system, by adequately utilizing reaction heat released during hydrogen absorption of the reaction beds of the hydrogen thermal compressors by virtue of metal hydride as well as sensible heat released during a cooling operation, the thermal efficiency of each hydrogen thermal compressor is improved, and the range and selectivity of waste heat utilization are expanded.

AI Technical Summary

Benefits of technology

This patented technology provides two types of systems for effectively handling large amounts of excessive temperature swings from one type of refrigeration machine (heat pump) used on another type of material being processed or stored. These systems are designed differently depending upon how much work it performs compared against what other machines they were previously installed without affecting their performance significantly over time. By doing this, these technologies help improve the overall effectiveness of the process by allowing more efficient usage of wasted resources like fuel while also reducing environmental concerns associated therewith.

Problems solved by technology

Technological Problem: Current methods for compressing high pressure hydrogen have limitations such as poor performance at higher temperatures due to heat transfer from one stage to another during operation (which can lead to reduced reliability). Additionally, current method requires multiple stages of compression resulting in lower efficiencies than desired.
