Description

一种高水位差趸船供应天然气的方法 A high-level gas supply method of difference barges

技术领域 FIELD

[0001] 本发明涉及天然气供应方法,尤其涉及一种高水位差趸船供应天然气的方法。 [0001] The present invention relates to a method for gas supply, in particular, relates to a method for high-level difference barges gas supply.

背景技术 Background technique

[0002] 趸船是无动力装置的矩形平底船,通常固定在岸边,最初仅作为浮码头使用,用于装卸货物或供行人上下,后随着时代的发展,人们生活品质的提高,逐渐对水上娱乐越来越热衷。 [0002] barge is no power plant rectangle punt, usually fixed on the shore, only the first floating dock used for loading and unloading cargo or for pedestrians up and down as after with the development of the times, people improve the quality of life, to gradually water recreation are increasingly interested. 基于如此,趸船也被用作商业、娱乐等使用。 Based on this, the barge also be used for commercial, recreational and other uses.

[0003] 目前,大多趸船上都设有供人们吃喝的饭店。 [0003] Currently, most people have to eat and drink for hotels on barges. 由于趸船漂浮在江河上,对于趸船上饭店厨房的燃气供应如果直接从陆地上连接天然气管道的话,所存在的问题是,天然气管道一般采用钢管,以保证管体的气密性、钢性和坚固性,从而避免气体发生泄漏现象。 Since the barge floating in the river, to the barge restaurant kitchen gas supply if the gas pipeline connecting it directly from the land, the problem is that the natural gas pipeline is generally used in the steel, to ensure the airtightness of the tubular body, rigidity and sturdiness , thereby avoiding leakage of gas occurs. 但是如果遇到汛期,河面升高,趸船便随之发生位移变化,由于钢管质地坚硬,天然气管道与趸船连接的地方便会发生皲裂现象,从而引起气体泄漏的问题。 But if you encounter flood season, the river rises, the barge will be followed displacement changes, due to the steel hard, local gas pipelines and barges connected chapped phenomenon will occur, thereby causing a problem of gas leakage. 而如果采用软管输送天然气体,由于管径小、管壁薄,无法承受管内燃气的压力,且不能满足趸船的用气量。 If using natural gas hose for conveying gas consumption due to the small diameter, thin wall, can not withstand the pressure of the gas inside the tube, and can not meet the barges.

[0004] 所以目前一般采用液化石油气来进行供气,但对于一罐净重13kg的液化石油气要满足多达2千人整日的饮食消耗量是远远不够的,所以在使用的时候需要不停的更换燃气管,这种方式所存在的问题是,如果断气时正处于炒菜阶段,会影响菜品的口感,从而影响商家的销售额;而且由于液化石油气属于易爆品,不易将其屯放在趸船上,所以需要人工每天搬运几罐液化石油气到趸船上,用完之后再将液化气罐搬下船去进行更换,这种方式操作繁琐且耗费人力。 [0004] Therefore, the current general use of liquefied petroleum gas to gas, but for liquefied petroleum gas jar net weight 13kg to meet as many as 2,000 people a day diet consumption is not enough, we need to use the time gas replacement stop, in this way there is a problem, is in the cooking stage if breathe, it will affect the taste of the dishes, which affects the sales of the business; and because LPG explosives belong, can not be readily Tun on barges, manual handling is required per day to several LPG tank barge, transporting the liquefied gas tank and then exhausted after getting off to be replaced, this tedious and labor-intensive manner. 一罐净重13kg的液化石油气燃烧后所能产生的热值,仅与16m 3天然气燃烧后所产生的热值相当。 13kg net heat value of a can can be generated by combustion of LPG, is comparable to a 16m 3 after heat value generated by combustion of natural gas. 一罐液化石油气价格一般在90元左右,而天然气按重庆地区商业用气价格2. 96元/m3计算,16m 3天然气价格仅需要50元左右。 LPG can of generally cost $ 90, while natural gas at commercial gas prices in Chongqing 2.96 yuan / m3 calculation, 16m 3 of natural gas prices need only about 50. 所以从价格方面来看, 液化石油气的成本远远高于气化天然气成本。 Therefore, from the price point of view, the cost of liquefied petroleum gas gasification is much higher than the cost of natural gas. 所以基于以上缺点,各趸船经营商都迫切的想要找到一种能直接向趸船供应天然气的方法。 So based on the above shortcomings, each barge operators are urgently want to find a way to be able to supply gas directly to the barge.
