Description
Technical field
The utility model belongs to the gas-fired equipment field, and it relates to a kind of natural gas peak-shaving device with intelligent flow control device.
Background technique
The characteristics of natural gas transmission and distribution be the upstream aerogenesis relatively evenly and downstream usefulness gas is inhomogeneous, peaking problem is very outstanding.As shown in Figure 1, China's peak regulation mode commonly used is to build some large-scale natural gas high pressure tanks 4, by rock gas high pressure tank 4 and admission line 1, outlet pipe 2, valve 31,32,33, reduction valve 5 is formed rock gas high pressure tank peak adjusting device, with the gas low ebb time, unnecessary rock gas is charged into rock gas high pressure tank 4 store, with the gas peak time, the rock gas of rock gas high pressure tank 4 stored is released the deficiency that remedies air demand.During peak regulation, the pressure of rock gas high pressure tank 4 can only be reduced to the force value of outlet pipe 2 at the most, cause rock gas high pressure tank 4 interior remaining a large amount of rock gases can't emit the input peak regulation, thereby the utilization ratio of rock gas high pressure tank 4 is not high.For satisfying the peak regulation requirement, have to throw huge fund and build many rock gas high pressure tanks 4 again, cause the huge consumption of state's financial capacity and take valuable land resources.
In addition, some large and medium-sized gases of China are many at present based on artificial coal gas, developed and had certain scale, have the low pressure gasholder group that peak regulation is used, design pressure is generally 1～6kPa (gauge pressure), and natural gas transmission and distribution and working pressure are than artificial coal gas height, rock gas low-pressure pipe network pressure is generally 30～50kPa (gauge pressure), therefore, behind artificial coal gas conversion rock gas, the low pressure gasholder group that original peak regulation is used or discardedly maybe need drop into a large amount of funds it is carried out key technological transformation.
For this reason, the inventor was August 9 calendar year 2001 in the applying date once, the patent No. is ZL01252963.X, denomination of invention is for providing the high-pressure natural gas that utilizes admission line 1 input as power source in the utility model patent of " novel natural gas peak adjusting device ", on the basis of original rock gas high pressure tank peak adjusting device, adopt the rock gas in the injection booster A suction rock gas high pressure tank 4 and promote its pressure and import new design that outlet pipe 2 carries out natural gas peak-shaving more as shown in Figure 2, a kind of novel natural gas peak adjusting device of this model utility, it comprises rock gas high pressure tank peak adjusting device, it is characterized in that also comprising by the valve on the pipeline 34,35,36 and by connecting tube 6, its left end links to each other with admission line 1 by flange 11 valves 34, right-hand member is welded on the gland 12 with holes, jet pipe 7, its left end links to each other with connecting tube 6 with packing ring 13 by gland 12 with holes and is supported on the suction chamber 8 left end sleeves 14, suction chamber 8, its left end is welding sleeve 14 and is linking to each other with gland 12 with holes by bolt, right-hand member links to each other with mixing tube 9 by welding, mixing tube 9, its left end links to each other with suction chamber 8 right parts by welding, right-hand member links to each other with diffuser pipe 10 by welding, diffuser pipe 10, its left end links to each other with mixing tube 9 right-hand members by welding, the injection increasing apparatus that right-hand member is connected to form by flange 11 ' and valve 36.
Though this utility model patent has improved the utilization ratio of gas holder, strengthened peak modulation capacity, but this utility model patent still exists deficiency, the Flow-rate adjustment that mainly is injection booster A is to be undertaken by the Flow-rate adjustment of the valve 34,35 that is attached thereto, thereby flow adjustment range is little, degree of regulation is also relatively poor, and energy loss is bigger in the Flow-rate adjustment, and adaptability is relatively poor.
