Abstract
The utility model discloses an air supply system for chemical plants. The system comprises an air compressor, a refrigeration dryer, an air storing tank, a nitrogen generating set and a nitrogen storing tank which are sequentially connected through pipelines. The system is characterized in that an instrument air outlet is formed in the air storing tank and connected with instruments through instrument air pipelines. The air supply system disclosed by the utility has the advantages that air is directly adopted to be supplied to the instruments, so that the nitrogen resource is saved and the air using cost of the plants is reduced.
Description
Technical field
The utility model relates to air feed equipment field, chemical plant, particularly a kind of chemical plant air supply system.
Background technique
In chemical industry, the chemical property of nitrogen is stable, and mainly as shielding gas, substitution gas, washing gas, safety guarantee gas, instrument usefulness gas etc., existing chemical plant all is as full station-service gas, especially instrument gas basically with nitrogen.Because the instrument sealing is relatively poor, cause nitrogen to leak easily, make factory with this increase of pneumatolytic.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art and defective, and a kind of chemical plant air supply system is provided, and this system can be chosen as it at different gas equipments air or nitrogen are provided, and greatly reduces the use amount of nitrogen, to address the above problem.
The technical problem that the utility model solved can realize by the following technical solutions:
The chemical plant air supply system, comprise the air compressor, cooling driers, air reservoir, nitrogen generator group, the nitrogen storage tank that connect successively, connect by pipeline between them, it is characterized in that, offer instrument usefulness gas outlet on described air reservoir, described instrument usefulness gas outlet is connected with each instrument with the tracheae line by instrument.
Owing to adopted technological scheme as above, the utility model directly adopts air to give the instrument air feed, has saved the nitrogen resource, reduced factory with pneumatolytic this.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Figure 1, the chemical plant air supply system comprises the air compressor 100 that connects by pipeline successively, cooling driers 200, air reservoir 300, nitrogen generator group 400 and nitrogen storage tank 500, air reservoir 300 tops offer instrument usefulness gas outlet 310, the outlet 310 of instrument usefulness gas is connected with instrument 620 with tracheae line 320 by instrument, instrument is with switch valve 330 is installed on the tracheae line 320, when switch valve 330 is opened, air in the air reservoir 300 can be offered instrument 620 uses, greatly reduce originally with pneumatolytic, nitrogen storage tank 500 is connected with nitrogen gas equipment 610, make this chemical plant air supply system to be chosen as it air or nitrogen are provided at different gas equipments, improved the utilization rate of nitrogen greatly, also reduced the use amount of nitrogen, reduced production costs.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
