Referring to Fig. 1, natural gas residual air retracting device after a kind of blowdown comprises filter 1, control valve 5, first blow-off pipe 4, separating barrel 6, second blow-off pipe 7, water inlet pipe 9, Pressure gauge 11, liquid level gauge 20, escape pipe 12, check-valves 14, first ball valve 10, second ball valve 13, the 3rd ball valve 8.
Filter 1 bottom is connected to first blow-off pipe 4, one end of first blow-off pipe 4 communicates with filter 1, the other end of first blow-off pipe 4 links to each other with separating barrel 6 middle parts, the impurity that contains natural gas after filtering through filter 1 can be discharged in the separating barrel 6, carries out natural gas residual air and reclaims.First blow-off pipe 4 is provided with control valve 5, can regulate the flow that the impurity that contains natural gas enters separating barrel 6, thereby reaches the effect of regulating gas pressure in the separating barrel 6, avoids separating barrel 6 internal pressures excessive.
Referring to Fig. 2, Fig. 3, separating barrel 6 comprises staving 16, bung 15, spherical tank net 17.Staving 16 and bung 15 select for use the metal that can satisfy the pressure-bearing condition to make, and the big I of staving 16 according to around environment be provided with, generally the pressure reduction by inlet pressure and outlet pressure calculates gained.Bung 15 is installed on staving 16 tops, forms airtight cavity, and spherical tank net 17 is arranged in the cavity.Spherical tank net 17 middle parts are the arc surface 18 to upper process, and arc surface 18 external diameter ends are equipped with filter screen 19, and filter screen 19 is circular, and filter screen 19 external diameters are identical with staving 16 internal diameters.
The bottom of separating barrel 6 links to each other with second blow-off pipe 7, and second blow-off pipe 7 is provided with the 3rd ball valve 8, and the impurity after handling through separating barrel 6 discharges by second blow-off pipe 7.
Separating barrel 6 tops are provided with water inlet pipe 9, escape pipe 12 and Pressure gauge 11.Water inlet pipe 9 one ends link to each other with outer water tube, and the other end of water inlet pipe 9 is arranged on separating barrel 6 inside, and water inlet pipe 9 is provided with first ball valve, 10, the first ball valves 10 in order to regulate the flow size of water in the water inlet pipe 9.Escape pipe 12 1 ends communicate with separating barrel 6 tops, and escape pipe 12 other ends link to each other with the outer low pressure pipe network, and are disposed with second ball valve 13, check-valves 14 on the escape pipe 12.Natural gas after separating barrel 6 filters is discharged from outside the separating barrel by escape pipe 12, enters into the outer low pressure pipe network.Pressure gauge 11 is used to detect the size of gas pressure in the separating barrel 6, guarantees that natural gas can enter into the outer low pressure pipe network smoothly.
Separating barrel 6 sides are provided with liquid level gauge 20, are used to observe the height of water level in the separating barrel 6.
In the utility model, the water inlet pipe 9 that is arranged on separating barrel 6 inside is positioned at arc surface 18 tops of spherical tank net 17, and water inlet pipe 9 mouths of pipe are downward.Water flows on the arc surface 18 of spherical tank net 17 through water inlet pipe 9 mouths of pipe, flows to filter screen 19 from arc surface 18 again, enters into separating barrel 6 inside by filter screen 19.4 of first blow-off pipes that extend into separating barrel 6 inside are positioned at arc surface 18 belows of spherical tank net 17, and first blow-off pipe, 4 mouths of pipe upwards.When the impurity that contains natural gas enters into separating barrel 6 inside by first blow-off pipe 4, the arc surface 18 at spherical tank net 17 middle parts can stop impurity, at the bottom of most of impurity is fallen to barrel, filter screen 19 on the spherical tank net 17 can filter the natural gas in the impurity simultaneously, and the natural gas that enters escape pipe 12 is met the demands.
The utility model is in off working state under most situation, promptly control valve 5, first ball valve 10, second ball valve 13, check-valves 14 and the 3rd ball valve 8 all are in closed condition.After having accumulated a certain amount of impurity in the filter 1, in the time of need carrying out blowdown to filter 1, the utility model is just started working.
The natural gas through filtration treatment is not passed in the filter 1 by air inlet pipe 2, and after filtering through filter 1, natural gas is transported to the outside network from the blast pipe 3 at filter 1 top, and the impurity after the filtration is then stayed filter 1 inside.After having accumulated a certain amount of impurity in the filter 1, will carry out blowdown to filter 1, thereby guarantee the normal operation of filter 1.
Before using the utility model, earlier air inlet pipe 2, blast pipe 3 are closed, open first ball valve 10, by water inlet pipe 9 a certain amount of water is poured in the separating barrel 6, operating personnel can be by the water level in liquid level gauge 20 definite separating barrels 6 of separating barrel 6 sides.
After pouring into a certain amount of water, close first ball valve 10, open second ball valve 13, again control valve 5 is opened certain angle, make the impurity that contains natural gas in filter 1, enter into separating barrel 6 inside by first blow-off pipe 4.
Owing to enter the below that first blow-off pipe, 4 mouths of pipe in the separating barrel 6 are positioned at spherical tank net 17, so 18 pairs of impurity of the arc surface at spherical tank net 17 middle parts play an effect that stops, most of impurity is fallen.Simultaneously, be mixed in natural gas in the impurity, carry out the second time and filter then by the filter screen on the spherical tank net 17 19.Natural gas after filtering for the second time enters into the escape pipe 12 that communicates with separating barrel 6 tops, and the check-valves 14 that is provided with on the escape pipe 12 is opened automatically, and natural gas just can enter into the outer low pressure pipe network smoothly.
After the discharging of the impurity in the filter 1 finished, when also no longer producing natural gas in the separating barrel 6, check-valves 14 just cut out automatically.After in case check-valves 14 cuts out, can respectively the control valve 5 and second ball valve 13 be closed, open the 3rd ball valve 8 simultaneously, the water that makes separating barrel 6 contain impurity is discharged outside the separating barrel 6 by second blow-off pipe 7, after water in separating barrel 6 all has been discharged, close the 3rd ball valve 8, filter 1 can recover to come into operation.
If when wanting separating barrel 6 washed, open first ball valve 10 and the 3rd ball valve 8, by the water in the water inlet pipe 9 filter screen on the spherical tank net 17 19 and staving 16 inwalls are washed, the water that wash passes through outside second blow-off pipe, the 7 discharge separating barrels 6.After flushing finishes, close first ball valve 10 and the 3rd ball valve 8 respectively.
The utility model can will once filter the impurity that is mixed with natural gas that is produced after the blowdown and refilter, and makes the natural gas in the impurity be reduced the production cost of enterprise by recycling fully, avoids environmental pollution.
