Description
Technical field
The utility model relates to a kind of LNG Liquefied natural gas air feeder, relates in particular to a kind of loader LNG Liquefied natural gas air feeder, belongs to fuel air feeder technical field.
Background technique
At present, the air feeder of loader all acts as a fuel with diesel oil both at home and abroad.But diesel combustion can produce a large amount of harmful gases, and air is polluted, as:
CO: the toxic gas that produces owing to partial combustion;
NOx: during the diesel engine heavy load, the mixed gas that is produced by nitrogen oxygen reaction under the condition of cylinder inner high voltage high temperature has great toxicity to blood, and people's lung, the heart, liver, kidney also had very big harm;
HC: the lubricant oil burning that spills from piston ring of diesel engine and valve guide bushing and the hydrocarbon that produces, comprise aromatic system, aliphatic and alicyclic etc., people's eye, nose, larynx and respiratory tract all there is very big harm;
PM: be by carbon, unburned or partially combusted lubricant oil and fuel, and the particulate matter of some sulfur oxide formation, can cause chronic disease such as bronchitis, pulmonary emphysema, also be one of carcinogenic reason.
In addition, use diesel oil to act as a fuel and also have other drawbacks: diesel oil can pollute animals and plants and water resources if be leaked in the soil; Need add additive in addition in the diesel oil,, cause the fuel pipe obstruction and loader can't normally be moved to prevent its wax deposition at low temperatures; The price of diesel oil is higher.
In recent years, developed the natural gas engine that is applicable to that Motor Vehicle uses in succession, rock gas is mainly mixed by gaseous state low molecular hydrocarbons and non-hydrocarbon gas and forms, products of combustion mainly is carbon dioxide and water vapor, the material of the harm humans respiratory health that produces is few, does not produce solid residue substantially.And rock gas is gas under atmospheric temperature, and proportion is light than air, in case leak, upwards diffusion immediately is difficult for gathering the formation explosive gas, can not pollute soil, and cheap (be about diesel-fuel price 70%), safe in utilization, advantages such as calorific value is high, cleaning had.
In sum, comparatively speaking, diesel oil is a kind of not environmental protection, not general, the energy that cost of use is higher, is a feasible scheme and use rock gas as the power fuel of loader, and developing the LNG Liquefied natural gas air feeder that is applicable to loader is a problem demanding prompt solution.
Summary of the invention
At above-mentioned existing technical problem, the utility model provides a kind of loader LNG Liquefied natural gas air feeder, the fuel of loader is become the rock gas of cleaning by traditional diesel oil, use the fuel of LNG Liquefied natural gas (LNG), reach the purpose of energy-saving and emission-reduction as loader.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of loader LNG Liquefied natural gas air feeder, comprise vaporizer, pressure maintaining valve, knock out drum and natural gas engine, also comprise LNG gas cylinder group, LNG gas cylinder group mainly is configured to propping up by two LNG gas cylinders, LNG gas cylinder horizontal arrangement is in support, two LNG gas cylinders are connected with vaporizer by fuel tube respectively, vaporizer is connected with pressure maintaining valve by fuel tube, pressure maintaining valve is connected with knock out drum by fuel tube, and knock out drum is connected with natural gas engine by fuel tube.
Further, support is dismountable, is fixedly mounted on the hood of loader.
Working principle of the present utility model:
At first, gaseous natural gas is lowered the temperature by refrigerating plant, when the temperature of rock gas arrives-160 ℃～-162 ℃, and air pressure is when arriving 0Mpa～0.1Mpa, and gaseous natural gas becomes liquid state;
Secondly, liquified natural gas (LNG) is filled in the double-deck adiabatic gas cylinder and store;
Then, LNG Liquefied natural gas (LNG) is joined in the LNG gas cylinder on the loader as power fuel, use for natural gas engine;
At last, during the LNG Liquefied natural gas (LNG) of natural gas engine in using the LNG gas cylinder, utilize the natural gas supply device that the rock gas of liquefaction, low pressure is heated up earlier, make it change gaseous state into by liquid state, after the air pressure for the treatment of gaseous natural gas is increased to 0.8Mpa～1.2Mpa, again itself and air mixing are burnt, for loader provides power.
The beneficial effects of the utility model are: 1, Pai Fang harmful gas is few; 2, the noise of Chan Shenging is low; 3, reduce the pollution that soil is caused; 4, gas fuel is applicable to throughout the year, not limited by ambient temperature; 5, fuel cost is cheap.

Fig. 2 is the structural representation of the utility model LNG gas cylinder group
Among the figure: 1, LNG gas cylinder, 2, support, 3, hood.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises vaporizer, pressure maintaining valve, knock out drum and natural gas engine, also comprise LNG gas cylinder group, LNG gas cylinder group mainly is made of two LNG gas cylinders 1 and support 2, LNG gas cylinder 1 horizontal arrangement is in support 2, and two LNG gas cylinders 1 are connected with vaporizer by fuel tube respectively, and vaporizer is connected with pressure maintaining valve by fuel tube, pressure maintaining valve is connected with knock out drum by fuel tube, and knock out drum is connected with natural gas engine by fuel tube.Further, support 2 is dismountable, is fixedly mounted on the hood 3 of loader.
Working procedure of the present utility model: when the driver prepared ato unit, with the fluid valve open of LNG gas cylinder group, the liquified natural gas in the LNG gas cylinder 1 then entered vaporizer by fuel tube earlier, and gasification is gas in vaporizer; When the pressure that is produced by gaseous natural gas in the vaporizer reached the force value of pressure maintaining valve setting, rock gas then can enter in the knock out drum by pressure maintaining valve, to wait for the startup of motor; When the driver opened ignition key switch, ato unit, the gaseous natural gas in the knock out drum then can enter in the natural gas engine, burns with air mixing.
In addition,, compare with the compression-ignited of diesel engine because the ignition mode of natural gas engine adopts Spark ignition type, poor slightly on dynamic response.In order to solve this deficiency, when this loader of exploitation, the dynamic response that motor that can adopt reduction of speed to increase to turn round and big capacity torque-converters improve complete machine.
