Description
Technical field
The invention belongs to high pressure gas storage equipment technical field, a kind of 5 tube frame formula natural fuelses (CNG) transportation long tube superimposed trailer particularly is provided.
Background technology
Natural fuels has become important energy source in daily life and the commercial production as a kind of clean energy resource.At present, the main mode of transport natural gas is the gas line transportation, but because the restriction of financial cost and the complexity of town and country planning, natural gas line can not cover all user areas in a short time, and the regional transport natural gas that does not cover to pipe network becomes a big demand in market.The natural gas transportation vehicle mainly contains LNG and two kinds of vehicles of CNG transport trolley at present, the LNG transportation is with natural fuels liquefy under-162 ℃ low temperature, pack into and transport territory of use in the accumulating jar, again being reduced to gaseous state again uses for the user, transportation exists higher secondary energy consumption, traffic cost height, uneconomical.CNG transportation be with the natural fuels compression to 20～25MPa, be transported to the user with the long tube superimposed trailer, it is convenient, flexible, do not exist secondary energy consumption and technological process simple, become from the gas distributing system to user between the main mode of transportation employing.
High pressure gas transportation long tube superimposed trailer is a kind of large pressurized vessel vehicle that is fixed with several or tens gas cylinders, mainly is made up of high-pressure gas bottle, chassis of semi-trailer, long tube framework, gas cylinder end plug, valve, pipeline, ready-packaged joint and safety device etc.The main vehicle of long tube superimposed trailer is for loading the 8-10 pipe superimposed trailer that diameter is the 559mm gas cylinder at present.
Above-mentioned existing natural fuels long tube superimposed trailer can be as the transportation of compression natural gas, but because the diameter of its gas cylinder has only 559mm, the maximum load volume of 8 tube frame formula long tube superimposed trailers is 19m under the situation that satisfies GB 1589-2004 " on-road vehicle contour dimension, axle load and quality limit value "
3The maximum load volume of 10 tube frame formula long tube superimposed trailers is 22.5m
3, but this vehicle only can be transported H
2The gas that equidensity is less.Prior art long tube superimposed trailer gas cylinder number is more, the manufacturing process of gas cylinder is comparatively complicated, need to form through a series of complex process manufacturings such as modified, ball blast, bottleneck processing, magnetic particle inspection, water test, air tight test, tightness test, inside and outside ball blast, ultrasonic flaw detection, applications, long tube superimposed trailer fitting process is also comparatively loaded down with trivial details in addition, becomes the major cause that the long tube superimposed trailer involves great expense.Therefore for many fortune body, less adorn gas cylinder, reduce the trailer manufacturing cost and use cost and need carry out brand-new design complete vehicle structure.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of long tube superimposed trailer, and the container of these long tube superimposed trailer splendid attire high pressure gas is that the diameter of novel development is the big volume seamless gas cylinder of 720mm.
The utility model is used for the frame-type 5 pipe range pipe superimposed trailers of accumulating natural fuels, comprises wheel, semi-trailer frame, long tube framework, is used for the gas cylinder of splendid attire natural fuels, and the long tube framework is installed in the vehicle frame top; Load 5 described gas cylinders in framework altogether, the upper strata is arranged 2, and lower floor arranges 3, and the gas cylinder diameter is 720mm; 5 gas cylinders vertically place in the long tube framework along the long tube framework; Along the long tube framework longitudinally afterbody be provided with operational window.
Innovative point of the present utility model is the containers of novel 720 type heavy caliber gas cylinders as the splendid attire high pressure gas, and 5 gas cylinders divide two-layer being arranged in the long tube framework up and down.Novel gas cylinder is that the 720 heavy caliber seamless steel pipe spinning that utilize novel spinning process newly to develop form, and the volume to weight ratio of novel gas cylinder improves a lot than 559 type gas cylinders of prior art.
The utility model long tube superimposed trailer shows with prior art long tube superimposed trailer parameter comparison such as table 1:
This utility model has following advantage as can be seen from Table 1:
1) higher volume to weight ratio.This car only needs two rows to divide two-layer being arranged in the long tube framework up and down with 3 * 25 gas cylinders.The gas cylinder diameter that is used for splendid attire CNG in the prior art is 559mm, and the utility model is used for the 720 type gas cylinders of the gas cylinder of splendid attire CNG for bigger specification, and 5 the 720 total water capacities of type gas cylinder reach 18.5m
3, the gas cylinder total weight only is 22450kg, basic identical with the gas cylinder weight (22400kg) of existing 8 pipe cars, volume to weight ratio reaches 0.824, has increased the volume of trailer, has reduced bicycle gas cylinder number, has improved the conveying efficiency of high pressure gas.Have conveying efficiency height, weight by volume than big, simple in structure, leakage rate is low, safe reliability is high, overall cost reduces advantages such as about 20% than traditional vehicle, economy is with the obvious advantage.
2) link still less, piping layout is more reasonable.720 type long tube superimposed trailers have only 5 gas cylinders to assemble, increased the load volume of frame-type long-tube trailer, reduced the quantity of bicycle use gas cylinder, reduced the manufacturing cost and use cost of long tube superimposed trailer, reduce the cost of making gas cylinder, reduced the usage quantity of annexes such as gas cylinder end plug, turnover air pipe, valve, rupture disk, the usage quantity of long tube superimposed trailer annex and the man-hour of car load assembling have been reduced, both saved the assembly cost of long tube superimposed trailer, convenient for users to use again, have the very strong market competitiveness.
