Description
Technical field
The present invention relates to the passenger vehicle of a kind of LNG Liquefied natural gas (abbreviating LNG as), be specifically related to a kind of combustion heater and corollary system thereof of the LNG of being used for passenger vehicle.
Background technique
LNG is the abbreviation of LNG Liquefied natural gas (liquefied natural gas); Main component is a methane; Its volume be about with amount gaseous natural gas volume 1/600, weight is merely with about 45% of water by volume; Calorific value is that (1MMBtu=2.52 * 108cal) is so advantage such as LNG has the calorific value height, pollutes less, accumulating is convenient is one of top quality energy of present a kind of clean environment firendly, efficient, convenient and safety to 52MMBtu/t.
Along with the ventilation of building up of transferring natural gas from the west to the east, engineering and Guangdong LNG engineering are sent in gas east, river, rock gas has become one of important urban energy of China.The passenger vehicle that with LNG is fuel is tending towards in a kind of growth of explosion type because of advantage such as its low emission, pollution-free, safe and convenient and economic benefit be superior.
Automobile used in winter; Because of temperature is low excessively, after starting, motor car engine can not in time get in the normal working state, and the tail gas of motor vehicle emission also is severe overweight; And the user also is uncomfortable, and this performance and environment to vehicle itself all produces adverse influence.So the season of cold automobile need be equipped with heater and solve these problems.The heater that present automobile is used all is to adopt fuel heater; Its working principle is: oil inlet pipe sprays into gasoline combustion heated cooling fluid or water; Cooling liquid is flowing in water inlet, the outlet pipe; Carry out heat exchange with the radiator under the instrument desk, make that vehicle interior temperature raises, the temperature the when temperature of motor car engine reaches its normal startup.
But fuel heater fits on the LNG passenger vehicle and uses, and has following problem:
One, the fuel of heater is diesel oil, then must be separately on the passenger vehicle lays a fuel tank for heater, then cause spatial arrangement not enough, and oils volatilization etc. and not environmental protection;
Two, because the fuel of vehicle motor is LNG, and the fuel of heater is diesel oil, so will add LNG and diesel oil respectively at every turn, makes troubles to operation.
Summary of the invention
The present invention will solve above-mentioned deficiency exactly, and a kind of combustion heater type LNG passenger vehicle of reasonable in design, safe and reliable and mutual coupling is provided, and realizes the coupling of heater and motor and gas burning system.
In order to reach above-mentioned effect; The present invention provides a kind of LNG passenger vehicle that is provided with combustion heater; Comprise motor, car inner radiator and LNG liquid container; And, also comprising combustion heater through pipeline and the tank connected vaporizer of LNG liquid storage, the outlet side of described vaporizer is connected with the air inlet end of described motor, combustion heater respectively through knock out drum; The feed-water end of said vaporizer, combustion heater is connected with the waterexit end of motor respectively; The waterexit end of said vaporizer is connected with the feed-water end of motor, and the waterexit end of said combustion heater is connected with the feed-water end of motor through radiator.
The performance of protection motor in cold especially needs to start earlier combustion heater for ease, and the waterexit end of said combustion heater is connected with vaporizer.
When starting combustion heater; Circulating water heating back supplies vaporizer heating vaporization LNG; Supply with combustion heater through the LNG of vaporization and heat use; The circulating hot water of heating is further supplied the vaporizer LNG that vaporizes again and is used then, another circulating hot water through radiator to the protection that heats up of air in the car and motor, ability ato unit after the temperature when making the temperature of motor car engine reach its normal startup.
After preventing that opening combustion heater earlier carries out preheating to motor; When restarting motor; Heater and motor are simultaneously to the hot circulating water of vaporizer supply; Because the combustion heater water pump is different sometimes with the engine water pumping pressure, supply the flow heated water of vaporizer to change and cause to meeting, then be difficult to guarantee the normal amount of vaporization of vaporizer.So the waterexit end at combustion heater is connected with vaporizer through water solenoid valve; Said water solenoid valve is electrically connected with vehicle power through relay; The input end of said relay is connected with the output terminal of motor.
The working power of relay is provided by vehicle power and motor respectively.When need start combustion heater earlier; Open vehicle power, normally-closed contact is closed behind the relay power, connects water solenoid valve; Thereby make the water route of combustion heater unobstructed; The hot water service of heating is heated vaporization LNG usefulness to vaporizer, acts as a fuel thereby the LNG of vaporization supplies with combustion heater again through knock out drum, has realized that promptly combustion heater normally uses separately.Be raised to the temperature of normal ato unit when vehicle interior temperature after, ato unit, then motor also is supplied to relay power; At this moment, provided by car load power supply and motor, motor participates in providing power supply; The relay normally-closed contact breaks off, and after the solenoid valve outage, the water cycle between combustion heater and the vaporizer is closed; Still be used as heating vaporization LNG by the motor hot-water supply to vaporizer, realize the motor and the common proper functioning of combustion heater of LNG passenger vehicle.
The invention has the beneficial effects as follows:
1, LNG passenger vehicle of the present invention has realized that motor and combustion heater together use LNG fuel, and combustion heater realizes using environmental protection fuel, and reduces user cost;
2, solving the client is the problem that motor and heater add fuel respectively, improves ease of use;
3, through the rational Match of gas burning system and water passage circulation system, improve the safety reliability in LNG passenger vehicle and the combustion heater using process.
