Description
Technical field
The utility model relates to a kind of Nitrogen plant of stopping machine automatically, and it is mainly used in the production of nitrogen.
Background technology
The PSA Nitrogen plant of present Nitrogen plant manufacturer production generally all can be put certain surplus in design in the Nitrogen plant, and the user also will consider certain surplus in choosing equipment, so that when increasing with gas later on, does not need to increase new equipment again; Both are comprehensive, and Nitrogen plant nitrogen gas purity occurs through regular meeting and be higher than design load, and nitrogen flow is lower than design load in operation, can have the situation of low load with strong power, and energy dissipation is serious.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, and can effectively control the Nitrogen plant of the machine of stopping automatically of nitrogen flow.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Nitrogen plant of stopping machine automatically, comprise air compressor, reaction tower and air line, connect by air line between air compressor and the reaction tower, it is characterized in that: it also comprises nitrogen buffer tank, accurate filter, nitrogen flow meter, nitrogen storage jar and PLC controller; Described reaction tower has two, is connected with nitrogen buffer tank by air line respectively, and nitrogen buffer tank is connected with accurate filter by air line; Accurate filter is connected with reaction tower with the nitrogen storage jar respectively by air line; On the air line between accurate filter and the nitrogen storage jar nitrogen flow meter is installed, the nitrogen flow meter is installed on the air line between accurate filter and the reaction tower; The PLC controller is connected with the nitrogen storage jar.
Nitrogen buffer tank described in the utility model, accurate filter and nitrogen storage jar all are connected with blow-off line.
Air line described in the utility model is provided with valve.
Be provided with the carbonaceous molecular sieve bed in the reaction tower described in the utility model.
The utility model compared with prior art has following positive effect: reasonable in design, can control nitrogen flow, good energy-conserving effect effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 reaction tower, 2 air lines, 3 nitrogen buffer tanks, 4 accurate filters, 5 nitrogen flow meters, 6 nitrogen storage jars, 7 carbonaceous molecular sieve beds, 8 blow-off lines, 9 valves, 10 sound dampers, 11PLC controller, 12 air compressor.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1, present embodiment mainly is made up of reaction tower 1, air line 2, air compressor 12, nitrogen buffer tank 3, accurate filter 4, nitrogen flow meter 5, nitrogen storage jar 6 and PLC controller 11, connects by air line 2 between air compressor 12 and the reaction tower 1; Reaction tower 1 has two, is connected with nitrogen buffer tank 3 by air line 2 respectively, and nitrogen buffer tank 3 is connected with accurate filter 4 by air line 2; Accurate filter 4 is connected with reaction tower 1 with nitrogen storage jar 6 respectively by air line 2; On the air line 2 between accurate filter 4 and the nitrogen storage jar 6 nitrogen flow meter 5 is installed, on the air line 2 between accurate filter 4 and the reaction tower 1 nitrogen flow meter 5 is installed; The PLC controller is connected with the nitrogen storage jar; Be provided with carbonaceous molecular sieve bed 7 in the reaction tower 1.
In the present embodiment, nitrogen buffer tank 3, accurate filter 4 and nitrogen storage jar 6 all are connected with blow-off line 8.
In the present embodiment, air line 2 is provided with valve 9, comes the flow direction of gas in the control air pipeline 2 by the switch of by-pass valve control 9.
During use, 1 one work of two reaction towers, a regeneration.At first, air compressor 12 pressurized air of purifying treatment is imported by air line 2 reaction tower 1 of working the bottom, generation nitrogen reaction tower 1 in; After nitrogen comes out from the top of reaction tower 1,, enter nitrogen buffer tank 3 and cushion by air line 2; The nitrogen that buffering is come out passes through the filtration of accurate filter 4 again.Nitrogen after the filtration, a part enters the reaction tower 1 of not working by nitrogen flow meter 5 and air line 2, in reaction tower 1, pass through carbonaceous molecular sieve bed 7 from top to bottom, filter out underproof nitrogen, qualified nitrogen enters air line 2 from the bottom of this reaction tower 1, and the sound damper 10 through 2 mouthfuls of air lines enters in the middle of the atmosphere again; Another nitrogen enters in the nitrogen storage jar 6 by nitrogen flow meter 5 and air line 2, directly uses for the user.
This is a complete Nitrogen plant work period, and the sampling spot of nitrogen pressure is in nitrogen storage jar 6 exits, and the current signal that provides by pressure unit is sent in the middle of the PLC controller 11 by analog module.When the nitrogen pressure in the nitrogen storage jar 6 rises to the set(ting)value of PLC controller 11, the Nitrogen plant orderly closedown; If air pressure does not descend in the regular hour section, provide the compressed-air actuated air compressor 12 also can auto stop.When the nitrogen pressure in the nitrogen storage jar 6 drops to the set(ting)value of PLC controller 11, the Nitrogen plant normal boot-strap; When if air pressure drops to setting pressure, air compressor 12 starts operation voluntarily, thereby accomplishes truly energy-conservation.
In addition, need to prove, specific embodiment described in this specification sheets, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
