Background technology
In recent years, fast development along with Chinese national economy, gas products range of application constantly expands, consumption is continuously increased, new product is constantly released, and purity improves constantly, and the market demand constantly expands, output value growth rate is considerably beyond the growth rate of the national economy total value same period, and pure nitrogen gas, argon, oxygen are the gas that in commercial production, purposes is quite varied.After separating liquefaction in air, transported with liquid before this during entering subpackage, store, then use it is dispensed in gas cylinder by gas packaging device, other common dispensing apparatus are storage tanks, liquid pump, carburator, filling station, between connected by pipeline, after a batch gas cylinder subpackage completes, the gas of liquid or gaseous state also it is filled with in pipeline, must empty in time, otherwise can raise gas expansion because of temperature, manifold pressure is excessive to explode, therefore can cause the great wasting of resources and increase operation cost, and some gas is also not suitable for directly discharging, air pollution can be caused.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, it is provided that a kind of gas concentration unit, is reclaimed by gas remaining in pipeline, reaches to economize on resources and increase the purpose of benefit.
The technical solution of the utility model:
nullThe retracting device of residual gas in a kind of pipeline，Comprise storage tank、Liquid pump、Carburator、Filling station，Storage tank、Liquid pump、Carburator and filling station connect, with pipeline, the gas packaging device that composition is complete the most successively，A threeway is respectively set up on pipeline between described liquid pump and carburator and between carburator and the row of filling，It is respectively the first threeway and the second threeway，Last interface of first threeway connects the 3rd threeway after connecting the first air valve，3rd threeway is connected with the air inlet of compressor，The gas outlet of compressor connects the 4th threeway，4th threeway is connected with last interface of the second threeway after connecting the second air valve，Last interface of 4th threeway connects the 5th threeway after connecting the 3rd air valve，5th threeway is connected with air accumulator，Last interface of 5th threeway is connected with last interface of the second threeway after connecting the 4th air valve，Above-mentioned all of connected mode is all connected by pipeline.
5th air valve is set between described carburator and the second threeway.
The amount of capacity of described air accumulator is 2-5 times of common gas cylinder.
One air pressure monitoring device is set between described air accumulator and the 5th threeway.
Compared with prior art, this utility model increases some pipe-lines on original gas dispensing apparatus, connect a compressor and an air accumulator, by air valve and the ingenious setting of pipeline, achieve to be compressed in air accumulator the residual gas in pipeline and save, after the gas canful preserved in air accumulator, adjust air valve, between gas cylinder is filled.This utility model simple in construction cost is low, simple to operate practical, not only safety and environmental protection, and has saved resource, decreases operation cost of enterprises, adds the performance of enterprises, is worth of widely use.

Fig. 1 is this utility model structural representation.
Detailed description of the invention
Embodiment 1:
nullThe retracting device of residual gas in a kind of pipeline，As shown in Figure 1，Comprise storage tank 1、Liquid pump 2、Carburator 3、Filling station 4，Storage tank 1、Liquid pump 2、Carburator 3 and filling station 4 connect, with pipeline 5, the gas packaging device that composition is complete the most successively，A threeway 6 is respectively set up on pipeline 5 between described liquid pump 2 and carburator 3 and between carburator 3 and the row of filling 4，It is respectively the first threeway 61 and the second threeway 62，First last interface of threeway 61 connects the 3rd threeway 63 after connecting the first air valve 71，3rd threeway 63 is connected with the air inlet of compressor 8，The gas outlet of compressor 8 connects the 4th threeway 64，4th threeway 64 is connected with last interface of the second threeway 62 after connecting the second air valve 72，Last interface of 4th threeway 64 connects the 5th threeway 65 after connecting the 3rd air valve 73，5th threeway 65 is connected with air accumulator 9，Last interface of 5th threeway 65 is connected with last interface of the second threeway 62 after connecting the 4th air valve 74，Above-mentioned all of connected mode is all connected by pipeline 5，Between described carburator 3 and the second threeway 62, the 5th air valve 75 is set，Between described air accumulator 9 and the 5th threeway 65, an air pressure monitoring device is set.
Close keeping the first air valve 71 and the second air valve 72, in the case of 5th air valve 75 is opened, normally the gas in storage tank 1 is carried out subpackage, after subpackage, close the air valve of storage tank 1, open the first air valve the 71, the 3rd air valve 73, close the second air valve the 72, the 4th air valve 74, open compressor 8, by the residual gas pressure recovery in pipeline 5 to air accumulator 9, close compressor the 8, first air valve 71 and the 3rd air valve 73 after recovery；When the gas reclaimed in the air pressure monitoring device on air accumulator 9 shows air accumulator 9 reaches a certain amount of or fills when, the first air valve 71 and the 3rd air valve 73 is kept to close, and close the 5th air valve 75, open the second air valve 72 and the 4th air valve 74, gas in air accumulator 9 enters in filling station 4 subpackage air inlet bottle by the 4th air valve 74 after compressor 8 compression flows through the second air valve 72, after subpackage completes, close compressor the 8, second air valve 72 and the 4th air valve 74, open the 5th air valve 75.
