Description
Technical field
This utility model relates to a kind of liquefied natural gas supplying device, is specifically a kind of asphalt mixing plant application liquefaction
Gas delivering pipe line structure.
Background technology
Along with expanding economy, the demand of the energy is also greatly improved, due to the use of conventional heat energy material, brings therewith
Bigger air pollution, from the winter of 2013, haze large area covered territory, so environmental protection pressure is bigger in recent years.
Highway construction is the basis of economic development, and road construction industry is also the industry that energy resource consumption is bigger, especially for
Meeting the demand of mechanized construction, be required to elevated heating processes, current heating fuel is mainly heavy oil, diesel oil and coal.This
Several fuel exhaust gas are the main discharge of poisonous waste source of atmospheric pollution, and the burning of these fuel has discharged substantial amounts of nitrogen oxygen
Compound, oxysulfide, flue dust, inhalable particles etc..These mixture have a strong impact on air quality, not only produce haze, cause
Some areas produce greenhouse effect temperature and raise, and they are mixed to form " acid rain " in the air at height, serious harm surface vegetation.
Chinese transportation Department of Transportation the most actively calls and clearly advocates the application of clean energy resource, liquefied natural gas (LNG) with cleaning, efficiently,
The characteristics such as low row, safety, will become the first-selection of road construction industry clean energy resource fuel.
Summary of the invention
The purpose of this utility model is: for the problem of above-mentioned existence, it is provided that a kind asphalt mixing plant application liquefaction
Gas delivering pipe line structure, solves to pollute in prior art environment, high in cost of production problem.
The technical solution adopted in the utility model is as follows:
The utility model discloses a kind of asphalt mixing plant application liquefied natural gas conveying pipeline structure, it is characterised in that
Including storage tank, tank car, carburetion system, heater, circulating water heating device, diffusion valve a, filter, effusion meter, regulator,
Diffusion valve b, described tank car is connected to storage tank by pipeline, and centre is provided with cryogenic globe valve, and described storage tank connects vapour by pipeline
Change system, carburetion system is made up of carburator a in parallel and carburator b, and the downstream of carburetion system is provided with heating system, heating system
System is made up of heater and pipeline connected in parallel, and pipeline is provided with ball valve, and heating system downstream is sequentially provided with ball valve, diffusion valve
A, Pressure gauge a, effusion meter, regulator, diffusion valve b, Pressure gauge b, the circulating water pipeline of described circulating water heating device connects
Heater, natural gas line is connected through the pipeline after regulator, and the natural gas line of circulating water heating is provided with ball
Valve.Wherein, liquefied natural gas is transported in storage tank by tank car by pipeline, and tank car can also be directly connected to carburetion system, and
In heating system, containing having heaters and pipeline connected in parallel, wintry weather temperature ratio is relatively low, through the natural gas of carburator vaporization
Temperature is too low, ambient temperature to be less than more than ten degree, is easily damaged the pipeline in downstream, needs the sky after vaporization
So gas carries out heat treated, and described heater uses heating in water bath, the when of heating, cuts out the pipeline in parallel with heater,
Open the ball valve of natural gas line on circulating water heating device, circulating water heating device is adjusted to duty, to recirculated water
Heating, natural gas is heated by the recirculated water after heating by heater, need not add natural gas in summer
The when of heat, open the ball valve in parallel with heater, close circulating water heating device.
Owing to have employed said structure, the asphalt mixing plant application liquefied natural gas transfer pipeline knot that this utility model provides
Colophonium particularly construction of the highway medium pitch can effectively be heated by structure, it is possible to adjusts corresponding according to the change of ambient temperature
Working method, i.e. heat the need of to the natural gas after vaporization, and the when of needing natural gas is heated,
Need not by the outside energy, convenient, flexible, meet different natural gas motorcar demands.
As improvement, described carburetion system uses the carburator of difference vaporization parameter, and described regulator is by two parallel connections
Pressure-regulating pipe constitute, every pressure-regulating pipe is sequentially provided with butterfly valve, pressure regulator, Pressure gauge, drain valve, described tank car and storage tank
Between pipeline be cryogenic metal hose.Vapour can be adjusted according to the actual demand of natural gas during actual natural gas motorcar
The mode of operation of change system, the most only carburator a, only carburator b, both common three kinds of mode of operations.Pressure-regulating pipe energy in parallel
Share the excessive damage of components brought of single pipeline pressure.Cryogenic metal hose can easily be by defeated for the liquid natural gas of tank car
Deliver to tank inside.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, construction of the highway Colophonium add hanker reduce the most cost-effective to the pollution of environment；
2, adjust carburetion system work aspect the most at any time, on the one hand meet different evaporating capacity demands, the opposing party
Face, reduce to single vaporization excessive bring icing, the problem such as damage of components；
3, free from the influence of the external environment natural gas after vaporization can be carried out self-heating, the when of aspect natural gas, subtract
Few damage to downstream line.
