A new safety-based self-adjustment system for nitrogen and hydrogen compressors and its working method

Abstract

The invention discloses a new safety-based nitrogen-hydrogen compressor self-regulating system and a working method thereof, comprising a gas cabinet, a Roots blower and a nitrogen-hydrogen compressor, wherein the nitrogen-hydrogen compressor is once closed once, twice once and one short circuit. In the self-adjusting state, the first circuit, the second circuit and the self-adjusting shortcut are linked with the height of the gas cabinet; the inlet and outlet pipes of the Roots fan are connected with the fan safety water seal; the height of the gas cabinet is as low as possible. The alarm and the low-low alarm are respectively linked with the nitrogen-hydrogen compressor once, twice, and a short-cut; the nitrogen-hydrogen compressor is provided with a DCS control system, and the DCS control system is provided with a gas cabinet height detector , to realize the detection of the height of the gas cabinet. By transforming the short circuit of the gas compressor and combining with the combined use of the safety water seal of the Roots blower, the invention eliminates the possibility of ultra-low and negative pressure pumping of the gas-generating gas cabinet, improves the safety of the production process, and achieves intrinsic safety. Purpose.

Description

Technical field[0001]The present invention relates to the field of chemical industry, and in particular, to a safety-based nitrogen hydrogen compressor self-tuning new system and its working methods.Background technique[0002]Small nitrogen fertilizer enterprises have still accounted for a large proportion in nitrogen fertilizer industry in my country. In my country's currently running small nitrogen fertilizer enterprises, gas compression is almost entirely using a nitrogen hydrogen compressor. A nitrogen hydrogen compressor is compared to other types of compressors, the minimum investment is the most mature, and it is normal, so it has a huge proportion in my country's small nitrogen fertilizer enterprises. However, as the state has strengthened the requirements of safety production requirements, the artificial manual adjustment of the circuit has become a bottleneck restricting the safe development of the industry. my country's small nitrogen fertilizer industry gas compression be...
