Description
Technical field
The utility model belongs to gas gasification and gas mixing device, particularly a kind of portable gas mixing station.
Background technology
Development simultaneously and rapidly through more than two decades and domestic economy, Chinese city combustion gas cause has entered unprecedented prosperity epoch, the a large amount of productions and the import of liquefied petroleum gas, the perforation of West-East National Gas Transmission Project, liquefied natural gas (LNG) and compressed natural gas (CNG) broad application, change original single relatively, artificial gas prevailing pipe gas general layout, formed the new situation that pipeline gas, compressed natural gas, liquefied natural gas, pipeline liquefied gas, liquefied gas mix many sources of the gas such as air, artificial coal gas and oil gas and deposit.Correspondingly some relevant issues also produce thereupon: many sources of the gas mix the security of supply; Along with the high speed development in city and the raising of resident living level, the combustion gas demand is constantly increased, be subjected to the condition restriction of peripheral source of the gas simultaneously, make the gas supply in many cities trend towards multi-source and multiple gas, for example combustion gas parent company in Shenyang is except that the self-produced oven gas in coke-oven plant, also introduce Liaohe Oil Field association natural gas from periphery, Fushun mine gas, and the liquefied gas that has a 10000NM3/h production capacity mixes air station (SNG) peak regulation source of the gas as a supplement.And all kinds source of the gas finally all enters the ring-like pipe network supply in city user; Wobbe index and combustion potential in guaranteeing the combustion gas mixing process roughly satisfy the customer requirements, how to define and guarantee that the security of mixed process and final gaseous mixture has become the problem of many gas companies care.The continuity of pipe gas supply: many industrial users are because the technology decision necessarily requires to reach the continuously uninterrupted air feed (as glass factory) of several years, important public good fortune user (as big hotel) also can propose the strict demand of air feed stability to air feed unit, the raising of realizing along with right-safeguarding in addition, ordinarily resident user is to causing the psychological bearing capability of stopping the supple of gas or steam also greatly to reduce because of the accident of pipeline network maintenance, take into account economic loss and social influence, just be necessary to solve the air feed discontinuous problem that unpredictalbe accident of pipeline network and periodic inspection cause.Economy in the pipe network user development: in the market expansion competition of fierceness, gas company often faces awkward situation at the temporary last arrival area of existing pipe network (usually in city's area edge or industrial area), throw huge fund and build a fixing liquefied gas station, although this station just may be in idle state after pipe gas arrives soon, just lose the user or the user that breaks one's promise, cause the certain economic loss, so gas company presses for a kind of solution that makes the best of both worlds.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of mobile gas mixing station is provided.This station is that Aolida Equipment Engineering Tech. Co., Ltd., Tianjin City is at above problem, for adapting to market demands, rely on 10 years leading technical advantages of industry, and nearly thousand gasification stations, over one hundred the rich experiences that gas mixing station is built are constantly brought forth new ideas, the multi-purpose combined type that design is produced moves gas mixing station, it makes great efforts to meet the need of market, and comes into operation at a plurality of stations, has obtained good effect.
The technical solution of the utility model is:
A kind of mobile gas mixing station is characterized in that: be by three independently gas source unit, mix the gas unit, control module combines:
Gas source unit: by the cylinder for liquefied gas connecting pipe, pipeline connects the gasifier that mixes the gas unit through liquid phase automatic transfer valve, high-pressure rubber pipe successively;
Mix the gas unit: connect high pressure ratio Gas mixing valve by gasifier, connect manually-operated gate, quick action emergency valve, check-valves, pressure regulator on its pipeline successively; Ratio Gas mixing valve opposite side is an air intake, connects manually-operated gate, quick action emergency valve, check-valves, pressure regulator on its pipeline successively; On liquefied gas inlet duct and the air intake pipeline control instrument pressure transmitter is housed.
Gas mixing station fire extinguisher inside, explosion-proof fan, combustible gas alarm instrument.
The utility model effect, characteristics and advantage:
This mobile gas mixing station is set up and is user-friendly to the mixing source of the gas, and the supply of liquefied gas is based on 50kg steel cylinder group.Consider easily that for safety and operation liquefied gas is without gas pressurized (as N2) or pump pressurization in the steel cylinder, pressure just can mix the middle pressure gaseous mixture of making 0.3～0.4bar, to be applicable to longer-distance air feed requirement during greater than 0.1Mpa.Adopt adjustable unsteady valve port proportion expression, same assembled moving gas mixing station can mix to be made for natural gas, for oil gas and for oven gas.In the control module design, by operating personnel's work in the environment out of doors, resting and reorganizing needs to consider.Each unit is separate, but the fork truck conveniently assemble and disassemble, the convenient common truck transport of exterior design, width is no more than 2.2 meters, and height should be able to be by the bridge or the railway culvert of 4.5 meters of limits for height.Link cable between each unit connects flexible pipe and all is prefabricated into the fast-assembling mode, and equipment transports to should be able to connect in 20 minutes behind the scene and finishes to user's air feed.Reach the continuity of pipe gas supply:
The assembled moving gas mixing station is applicable to the air feed of keeping of multiple source of the gas pipe network maintenance occasion.Before repairing work begins, each unit of mobile gas mixing station can be transported to the suitable place of downstream pipe network with truck, lay stable back and arrange interim safety measure, start and mix the front and back valve that gas equipment downstream can closing fault repairing point behind the air feed.In case repairing finishes, mobile gas mixing station can conveniently be removed by fork truck and truck.Simultaneously, for some industrial user's initial stage atm number baking kiln, igniting debugging and public good fortune, civilian users be at the unconventional amount gas of certain specific period (as the Spring Festival), and portable gas mixing station also can be brought into play standby and the function peak regulation source of the gas.
Economy in the pipe network user development: when being positioned at certain gas distributing system in the factory that gets final product arrival area after a year, hotel and machine-operated when gas company proposition air feed requires, the assembled moving gas mixing station just becomes most economical selection.With respect to building the fixedly gas mixing station that may leave unused future, it is low that the assembled moving gas mixing station has investment, duration is short, engineering handing-over interface and the few advantage of workload, and after the pipe network combustion gas arrives, be movable to farther area that pipe network also not do not arrive as the movement station air feed, or as the equipment of speedily carrying out rescue work of pipe network.Its dominance economic benefit and recessive economic benefit are all apparent in view.
Mobile gas mixing station is used for the alternative source of the gas use that gas pipeline is speedily carried out rescue work, and also uses applicable to the gas peak regulation tonifying Qi simultaneously.Can be used for newly opening up the outer combustion gas user air feed service of pipe network.
