Description

It is a kind of using air compressor as empty nitrogen mutually for the nitrogen supply system of compressor standby host
Technical field
It is a kind of using air compressor as empty nitrogen mutually for the nitrogen supply system of compressor standby host, belong to space division system technology neck Domain.
Background technology
When air separation unit produces nitrogen, general four nitrogen compressors are run simultaneously can meet production requirement, and four nitrogen Press wherein one is empty nitrogen mutually for compressor.In nitrogen compressor daily maintenance or nitrogen compressor failure process, System nitrogen demand cannot be met so that total system reduces produce load influences product yield simultaneously(Influence hydrazine yield about 2t/ h).
Utility model content
Still it can meet when repairing, safeguard the technical problem to be solved by the utility model is to provide a kind of nitrogen compressor The nitrogen supply (NS) system of system nitrogen demand.
In order to solve the above technical problems, technical solution used by the utility model:It is a kind of using air compressor as sky Nitrogen is mutually for the nitrogen supply system of compressor standby host, including empty nitrogen compressor, empty nitrogen compressor standby host, nitrogen compressor outlet header, oil removing Device, nitrogen storage tank, cyclone separator, the sky nitrogen compressor, the nitrogen of empty nitrogen compressor standby host enter nitrogen compressor outlet header Afterwards Nitrogen pipe network is re-fed by oil expeller, nitrogen storage tank, cyclone separator successively;
The sky nitrogen compressor one side is equipped with the first air into piping, the first nitrogen into piping, and it is empty that opposite side is equipped with first Gas goes out piping, the first nitrogen goes out piping, the sky nitrogen compressor standby host one side be equipped with the second air into piping, the second nitrogen into Pipe, opposite side goes out piping equipped with the second air, the second nitrogen goes out piping, and first air goes out piping, the second air goes out piping It is connected with external instrument air storage tank, it is total with nitrogen compressor outlet that first nitrogen goes out piping, the second nitrogen goes out piping Pipe connects, and first nitrogen provides nitrogen into piping into piping, the second nitrogen by air separation unit.
First air goes out piping, the second air goes out piping, the first nitrogen goes out piping, the second nitrogen goes out piping and is all provided with There is showering guilding valve.
Compared to the prior art the utility model has the advantages that:The utility model is by increasing nitrogen inlet/outlet pipe Line transform air compressor of the prior art as sky nitrogen compressor standby host, in the case where not increasing equipment cost, increases The supply of nitrogen so that nitrogen compressor repair, safeguard when nitrogen supply (NS) amount can also be guaranteed, while also avoid Because nitrogen amount deficiency causes the fluctuation of system and then influences product yield.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
In figure, 1 is empty nitrogen compressor, and 2 be empty nitrogen compressor standby host, and 3 be nitrogen compressor outlet header, and 4 be oil expeller, and 5 are Nitrogen storage tank, 6 be cyclone separator, and 11 go out to match somebody with somebody into piping, 13 for the first nitrogen into piping, 12 for the first air for the first air Pipe, 14 go out piping for the first nitrogen, and 21 go out to match somebody with somebody into piping, 23 for the second nitrogen into piping, 22 for the second air for the second air Pipe, 24 go out piping for the second nitrogen.
Specific embodiment
As shown in Figure 1, it is a kind of using air compressor as empty nitrogen mutually for the nitrogen supply system of compressor standby host, including empty nitrogen pressure Contracting machine 1, empty nitrogen compressor standby host 2, nitrogen compressor outlet header 3, oil expeller 4, nitrogen storage tank 5, cyclone separator 6, the sky nitrogen Compressor 1, the nitrogen of empty nitrogen compressor standby host 2 enter after nitrogen compressor outlet header 3 successively by oil expeller 4, nitrogen storage tank 5, Cyclone separator 6 is re-fed into Nitrogen pipe network;
1 one side of sky nitrogen compressor is equipped with the first air into piping 11, the first nitrogen into piping 12, and opposite side is equipped with the One air goes out piping 13, the first nitrogen goes out piping 14,2 one side of sky nitrogen compressor standby host be equipped with the second air into piping 21, Second nitrogen is into piping 22, and opposite side goes out piping 23 equipped with the second air, the second nitrogen goes out piping 24, and first air goes out to match somebody with somebody Pipe 13, the second air go out piping 23 and are connected with external instrument air storage tank, and first nitrogen goes out piping 14, the second nitrogen Go out piping 24 to connect with nitrogen compressor outlet header 3, first nitrogen is into piping 12, the second nitrogen into piping 22 by space division Device provides nitrogen.
First air goes out piping 13, the second air goes out piping 23, the first nitrogen goes out piping 14, the second nitrogen goes out to match somebody with somebody Pipe 24 is equipped with showering guilding valve.
The sky nitrogen compressor 1 and empty nitrogen compressor standby host 2 should close simultaneously when opening nitrogen inlet valve, nitrogen outlet valve Air inlet valve, air outlet valve are closed, similarly should simultaneously close off nitrogen inlet when opening air inlet valve, air outlet valve Valve, nitrogen outlet valve, it is ensured that only pipeline works all the way for nitrogen pipeline, air line.Empty nitrogen compressor 1 and empty nitrogen compressor are standby The use of machine 2 determines compressed air or nitrogen according to practical condition.
It is to transform air compressor as sky nitrogen compressor standby host 2 compared with prior art in the present invention, in addition existing An existing empty mutual standby host of nitrogen in technology, starts work in nitrogen deficiency together, and other three nitrogen of the prior art The nitrogen outlet of press is equally communicated to nitrogen compressor outlet header 3.
Above-described embodiment is the explanation to the utility model structure and unrestricted, is not departing from the utility model principle premise Lower made deformation is also within the scope of protection of the utility model.
