Description

Technical Field

[0001] This utility model relates to a high-pressure gas supply system for a nitrogen generator. Background Technology

[0002] High-pressure air is a widely used "power source" and "process medium" in industrial workshops, mainly applied in scenarios such as power drive and automation control, surface treatment and cleaning, process assistance and special processing.

[0003] The core function of a high-pressure gas nitrogen generator in a workshop is to produce high-purity nitrogen (usually 95%~99.999%) by separating air, and to store or use it directly in a high-pressure form (such as 10~40 MPa). It is mainly used in metal processing and heat treatment, chemical and energy security, and electronic manufacturing.

[0004] In the existing technology, the nitrogen generator has only one air supply pipeline, and this pipeline simultaneously supplies high-pressure air to both the industrial workshop and the nitrogen generator. This often leads to excessive load on the air compressor in this pipeline, affecting the service life of the air compressor. At the same time, the amount of high-pressure air required by the nitrogen generator is often insufficient. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a high-pressure gas supply system for a nitrogen generator.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-pressure gas supply system for a nitrogen generator, including a nitrogen generator, wherein a main gas supply pipeline and an auxiliary gas supply pipeline are connected in parallel to the gas inlet of the nitrogen generator, and the main and auxiliary gas supply pipelines are respectively composed of an air compressor, a gas storage tank, a dryer and a filter connected in sequence along the airflow direction.

[0007] Preferably, a one-way valve is provided on the main gas supply pipeline in front of the connection point where it is connected in parallel with the auxiliary gas supply pipeline, and the one-way valve is located behind the filter of the main gas supply pipeline.

[0008] Preferably, the main gas supply pipeline is also connected to a high-pressure gas supply pipeline leading to the workshop between its filter and the one-way valve.

[0009] Preferably, each of the condensate drain outlets of the dryer is connected to an exposed main drain pipe, the end of each main drain pipe is connected to an automatic drain valve, and the drain outlet of each automatic drain valve is connected to a drain hose.

[0010] Preferably, a main drain switch valve is installed on the main drain pipe in front of the automatic drain valve.

[0011] Preferably, the side of the main drain pipe is connected to a branch drain pipe in front of the automatic drain valve.

[0012] Preferably, each of the branch drain pipes is equipped with a branch drain switch valve.

[0013] Compared with the prior art, the present invention has the following advantages: the high-pressure air supply system of the nitrogen generator adopts two parallel air supply pipelines to supply air simultaneously. The two air supply pipelines are the main air supply pipeline and the auxiliary air supply pipeline, which can increase the supply of high-pressure air, so that the high-pressure air volume can meet the needs of both the industrial workshop and the nitrogen generator. In addition, the load on the air compressor of a single air supply pipeline is reduced and it is not easy to be damaged.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0017] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] like Figure 1 As shown, this embodiment provides a high-pressure gas supply system for a nitrogen generator, including a nitrogen generator 1. A main gas supply pipe 2 and an auxiliary gas supply pipe 3 are connected in parallel to the gas inlet of the nitrogen generator. The main and auxiliary gas supply pipes are each connected in sequence along the airflow direction by an air compressor 4, a gas storage tank 5, a dryer 6, and a filter 7.

[0020] In this embodiment of the present invention, a one-way valve 8 is provided on the main gas supply pipeline in front of the connection point where it is connected in parallel with the auxiliary gas supply pipeline. The one-way valve is located behind the filter of the main gas supply pipeline.

[0021] In this embodiment of the present invention, a high-pressure gas supply pipeline 10 leading to workshop 9 is also connected between the filter and the one-way valve on the main gas supply pipeline.

[0022] In this embodiment of the utility model, the drain outlet of the condensate of the dryer is connected to an exposed main drain pipe 11, the end of the main drain pipe is connected to an automatic drain valve 12, and the drain outlet of the automatic drain valve is connected to a drain hose 13.

[0023] In this embodiment of the utility model, a main drain switch valve 14 is installed on the main drain pipe in front of the automatic drain valve.

[0025] In this embodiment of the utility model, each branch drain pipe is equipped with a branch drain switch valve 16.

[0026] In this embodiment of the utility model, the working principle of the high-pressure air supply system for the nitrogen generator is as follows: two parallel air supply pipelines are used to supply air simultaneously. The two air supply pipelines are the main air supply pipeline and the auxiliary air supply pipeline, which can increase the supply of high-pressure air, so that the high-pressure air volume can meet the needs of both the industrial workshop and the nitrogen generator. In addition, the load on the air compressor of a single air supply pipeline is reduced, making it less prone to damage.

[0027] In the main and auxiliary air supply pipelines, the condensate from the dehumidified air by the dryer is discharged through the drain hose of the automatic drain valve. At this time, the main drain valve is normally open and the branch drain valve is normally closed.

[0028] When maintenance is required, the branch drain valve can be opened to drain water simultaneously using the branch drain pipe.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
