Abstract
In the gas pipe net system comprising gas source tank, compressor, main pipeline, pressure regulator and courtyard user pipeline, low pressure gas holder is set in the courtyard user pipeline and has bypass pipe communicated to rear courtyard user pipeline. The said gas holder can supply gas to rear user at the gas peak period and can store gas at the gas valley period for the peak regulation. The present invention has simple and reasonable structure and can maintain the stable gas pressure in user's end.
Description
The present invention relates to a kind of device that is used to store the city inflammable gas, particularly a kind of low pressure rear-end regulating peak gas pipe net system.
At present, the inflammable gas that use in China cities and towns mainly is to concentrate aerogenesis, air storage and pipe network gas transmission form, and it consists essentially of air storage, the air supply system that is made of source of the gas cabinet, compressor, the person in charge net, regulator, garden and indoor pipeline.Because the city gas consumption is inhomogeneous, the load variations of gas distribution system, gas network is very big.Evenly produce air feed and the inhomogeneous contradiction with gas of user for solving source of the gas factory, and guarantee usefulness gas peak user's needs, current gas distribution technological scheme all is at the pipe network front end gas storage holder peak regulation to be set, and compressed again machine boosts, and delivers to the user by pipe network.The ability of supplying gas of compressor, pipeline, controlling device etc. must be chosen definite by peak gas consumption numerical value in the pipe network system, so all corresponding increases such as bore, capacity and power of the said equipment in the existing gas pipe net system, the also corresponding raising of its investment cost all brings certain trouble for operation and maintenance.And its peak regulation effect is not ideal enough, and gas pressure is also stable inadequately.
The objective of the invention is to overcome outside the deficiency that has in the technology, propose a kind of reasonable in design, simple in structure, little investment, the operation and maintenance facility, supply gas pressure is stable, caisson and compressor, transmission and distribution network and the low pressure rear-end regulating peak gas pipe net system that the pressure governor peak load is little and energy consumption is low.
Purpose of the present invention can reach by adopting following technical proposal: in the gas distribution pipe network system that is made of source of the gas cabinet, compressor, gas line network, pressure governor and the indoor pipeline of garden, be positioned on the indoor pipeline of garden of pressure governor low pressure rear-end the low pressure air-storage chamber is set, air-storage chamber is placed in the rare safety zones extremely of personnel such as building top; Draw bypass tube is connected with rear end garden user pipeline from low pressure gas storage chamber bottom.By this bypass tube the user of rear end is carried out peak air feed, low ebb gas storage and peak-shaving.For obtaining better effect is provided with reservoir hag and top band balancing weight thereof in described low pressure air-storage chamber top board, this panel edges is provided with some uniform rollers and moves up and down along the corresponding positioning guide rail of vertically setting up.
Accompanying drawing 1 is a systematic square frame schematic representation of the present invention
Accompanying drawing 2 is the structural representation of system of the present invention mesolow air-storage chamber.
Below in conjunction with embodiment and accompanying drawing the present invention is described in further detail.The air demand of certain town gas pipe network system is 5 cubic meters per day, wherein civilian is 74%, industrial is 26%, adopt a source of the gas gas holder, three compressors, 6 cover controlling devices and mesolow secondary network system come transmission ﹠ distribution coal gas, and source of the gas factory pressurizing point outlet gas pressure is 50 kPas, and surge-chamber outlet gas pressure is 1.5 kPas.Routinely its peak hour calculated flow rate of design of pipe networks be 7067 cubic metres/time.Now low pressure rear-end is a load cell with housing-group, Lou Dong, sets up 70 of the low pressure air-storage chambers of different size respectively in homes such as building tops, wherein: 100 cubic metres 26,50 cubic metres 34,20 cubic metres 10.Under this condition pipe network system peak hour calculated flow rate reduce to 4131 cubic metres/time.The contrast of pipe network system capital equipment parameter of the embodiment of the invention and design routinely is referring to subordinate list.Above-mentioned low pressure air-storage chamber is by brick or give the chamber body (1) of system block structure, and the top board (4) of reservoir hag that is placed in one (2) and top band balancing weight (3) thereof and four positioning guide rails (5) that are erected in chamber body (1) inboard constitute.The edge of top board (4) is evenly equipped with four rollers (6), and each roller (6) contacts with relative positioning guide rail (5) respectively, and drives top board (4) along its scroll-up/down.Chamber body (a 1) bottom bypass tube of installing (7) is connected with the garden user pipe of rear end.Adopt pipe network system transmission ﹠ distribution coal gas of the present invention with the gas low ebb time, to carry out air storage by all the low pressure air-storage chambers to the rear end, with the gas peak time, storage coal gas is sent the deficiency that additional pipe network is supplied gas, reach the purpose of peak regulation.
The present invention compared with prior art, because of decrease gas storage holder, pipe network, compression The specification of machine and adjusting device and investment cost is few, and it is stable with atmospheric pressure to have a user, Safe, but the characteristics such as gas dome easy maintenance automatic job. Therefore can be used to design and dig Dive and transform the City Gas Distribution pipe network system, improve its economic benefit and social benefit.
