Nitrogen-hydrogen compressor self-adjusting system based on safety and working method thereof

Abstract

The invention discloses a nitrogen-hydrogen compressor self-adjusting system based on safety and a working method thereof. The system comprises a gas holder, a Roots blower and a nitrogen-hydrogen compressor. A first-return first-near path and a second-return first-near path of the nitrogen-hydrogen compressor are in a self-adjusting state, and a first-return first-self-adjusting near path and a second-return first-self-adjusting near path are interlocked with a height of the gas holder. An inlet pipeline and an outlet pipeline of the Roots blower are connected with blower safety water seal. The height of the gas holder is interlocked with the one-return one-near path and the two-return one-near path of the nitrogen-hydrogen compressor according to low alarm and very low alarm. A DCS control system is arranged in the nitrogen-hydrogen compressor, and a gas holder height detector is arranged in the DCS control system to detect the height of the gas holder. In the invention, the near path of the gas compressor is reconstructed, and the safe water seal of the Roots blower is combined for use so that a possibility of ultralow pressure and negative pressure pumping of a gas-making gas holder is avoided, safety of a production process is improved, and a purpose of intrinsic safety is achieved.

Description

technical field [0001] The invention relates to the technical field of the chemical industry, in particular to a new safety-based self-adjustment system for a nitrogen-hydrogen compressor and a working method thereof. Background technique [0002] Small nitrogen fertilizer enterprises still account for a relatively large proportion of the nitrogen fertilizer industry since their development in my country. Among all the small nitrogen fertilizer enterprises currently in operation in my country, almost all gas compression uses nitrogen and hydrogen compressors. Compared with other types of compressors, nitrogen-hydrogen compressors have the smallest investment, the most mature technology, and normal operation, so they occupy a huge proportion in my country's small nitrogen fertilizer enterprises. However, as the country's requirements for safe production are increasingly strengthened, the problem of manual adjustment of the circuit has become a bottleneck restricting the safe ...
