Abstract
The utility model discloses a helium-nitrogen mixture recycling gas supply system. The system is connected to a gas receiver in a loop manner. A gas outlet pipeline of the gas receiver is connected with a gas consumption point through a pressure reduction and stabilization device and a dry filter. The gas consumption point is simultaneously connected to a low-pressure buffer tank used for precipitating impurities, and the gas consumption point and the low-pressure buffer tank are switched through a control valve arranged between the gas consumption point and the low-pressure buffer tank. A gas outlet pipeline of the low-pressure buffer tank is connected to a gas inlet pipeline of the gas receiver through gas storage bags, a diaphragm compression unit and an oil separator. Tail gas of the helium-nitrogen mixture can be fully recycled and utilized, and accordingly the helium-nitrogen mixture recycling gas supply system is energy-saving and environment-friendly, high gas quality can be guaranteed, and production cost is reduced greatly.
Description
Technical field
The utility model relates to a kind of air supply system, is specifically related to a kind of helium nitrogen mixed gas circulation and reclaims air supply system.
Background technology
The helium nitrogen mixed gas is by helium and nitrogen configuration as a kind of binary gas mixture, is applied in technical fields such as commercial production such as leak detection more.At present aborning, the helium nitrogen mixed gas tail gas after a large amount of the use adopts the mode of direct emptying mostly, and the helium waste that belongs to high value rare gas is serious, has certain potential safety hazard again.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and providing a kind of can recycle helium nitrogen mixed tail gas, reclaims air supply system with the helium nitrogen mixed gas circulation that reaches the purpose that reduces production costs.
Air supply system is reclaimed in a kind of helium nitrogen mixed gas circulation; Being the loop is connected on the air accumulator; The outlet pipe of said air accumulator is through subtracting stable-pressure device and device for drying and filtering and being connected with the gas point; This is connected the low pressure buffer jar that is used for precipitated impurities simultaneously with gas point, and said with gas point and the control valve realization switching of low pressure buffer jar through being provided with between it, the outlet pipe of said low pressure buffer jar is connected on the air inlet pipeline of air accumulator through reservoir hag, diaphragm type compressor group, oil eliminator.
The utility model can carry out abundant recycle with the helium nitrogen mixed gas tail gas after using, not only energy-conserving and environment-protective, and can guarantee the high-quality makings amount of using, significantly reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is further specified.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
Referring to Fig. 1; Air supply system is reclaimed in a kind of helium nitrogen mixed gas circulation that the utility model provided; Being the loop is connected on the air accumulator 1; The outlet pipe of said air accumulator 1 is through subtracting stable-pressure device 2 and device for drying and filtering 3 and being connected with gas point 4 (the helium nitrogen mixed gas tail gas after the use is through this place); This is connected the low pressure buffer jar 5 that is used to precipitate tiny particle such as dust, welding slag simultaneously with gas point 4, and said with gas point 4 and the control valve 6 realization switchings of low pressure buffer jar 5 through being provided with between it, the outlet pipe of said low pressure buffer jar 5 is connected on the air inlet pipeline of air accumulator 1 through reservoir hag 7, diaphragm type compressor group 8, oil eliminator 9.
Air accumulator 1 can adopt pressure to be less than or equal to the middle pressure air accumulator of 10.0Mpa as air supply source; Gaseous mixture by pipeline be delivered to subtract stable-pressure device 2 after; Reduce pressure into 6.0Mpa voltage stabilizing output, get into device for drying and filtering 3 and remove water treatment, gaseous mixture is transported to terminal usefulness gas point 4 through pipeline.
After gas uses; Deliver gas to low pressure buffer jar 5 through switching control valve 6; Tiny particle such as the dust in the gaseous mixture, welding slag gets into reservoir hag 7 at this post precipitation, when the gas of storage in the reservoir hag 7 has arrived certain gas flow (through the infrared ray locating alarming); Open diaphragm type compressor group 8, gaseous mixture is stored for future use by the high pressure entering air accumulator 1 that normal pressure rises to 10.0Mpa.
Claims (1)
