AI Technical Summary
In existing ammonia synthesis equipment, high-frequency vibrations caused by gas pulses lead to equipment wear and safety risks, while existing buffers are either costly or have low buffering efficiency.
Design a synthetic ammonia feed buffer mechanism to convert the kinetic energy of gas pulsation into elastic potential energy and the compressive potential energy of the circulating gas buffer tank. Utilize elastic buffer components to attenuate vibrations, including a flow reduction component and an elastic buffer component, combined with a shock absorber and a flow deflector to convert kinetic energy step by step.
It significantly attenuates high-frequency vibrations, improves buffering efficiency and effectiveness, reduces pulse energy consumption, extends equipment life, and reduces maintenance requirements.
