Abstract
The invention relates to a diesel oil-LNG (Liquefied Natural Gas) dual-fuel LNG tank car capable of directly taking gas from an LNG tank car storage tank, which consists of an LNG supply system and a diesel oil-LNG dual-fuel system, wherein the LNG supply system directly takes gas from the LNG tank car storage tank and mainly consists of the LNG storage tank, a low-temperature metal hose, an LNG carburetor and a pressure-reduction and pressure-stabilizing valve, and the diesel oil-LNG dual-fuel system mainly consists of two parts of a natural gas control system and an electronic control system. The car can work in a diesel oil-LNG dual-fuel state and can also work in a total diesel oil state. The dual-fuel work state is controlled by an electronic conversion switch.
Description
Technical field
The present invention is applied to fields such as the production of LNG tank car and repacking, belongs to diesel oil---the natural gas vehicle by double fuels technology.
Technical background
At present, domestic existing diesel-LNG hybrid fuel LNG tank car mainly is to install vehicle-mounted LNG storage tank on the LNG tank car additional, and the vaporization of the LNG in vehicle-mounted LNG storage tank back is used for driving engine, has a lot of shortcoming and defect:
1, taken tank car available space, increased the load of tank car, influence the safety traffic of vehicle;
2, because the space of tank car is limited, and the volume of vehicle-mounted LNG storage tank is subjected to certain restriction, and entrained LNG is less, the continual mileage of tank car is shorter;
3, vehicle-mounted LNG storage tank is installed, has been increased cost;
4, vehicle-mounted LNG storage tank is filled LNG and need build the LNG gas station, very big input.
These shortcoming and defect have seriously restricted the repacking and the popularization of diesel-LNG hybrid fuel LNG tank car.
Summary of the invention
Main purpose of the present invention is to overcome the shortcoming that diesel-LNG hybrid fuel LNG tank car exists, and improves the fuel amount of carrying, and increases continual mileage, solves aerating and is subjected to problems such as gas station restriction, to promote the large-scale development of diesel-LNG hybrid fuel LNG tank car.
The present invention is achieved through the following technical solutions:
1, the diesel-LNG hybrid fuel LNG tank car of directly getting gas from the tank car storage tank is made up of LNG gas supply system and diesel oil-natural gas double-fuel system.
2, directly get the diesel-LNG hybrid fuel LNG tank car of gas, directly get gas, after vaporization and heating, use for driving engine from the by pass valve or the liquid valve of the LNG storage tank of tank car from the tank car storage tank.
Described LNG gas supply system is made up of LNG storage tank, low-temperature metal flexible pipe, LNG carburetter, decompression venting valve.After LNG that flows out from the LNG storage tank of tank car or cryogenic natural gas enter vaporization of LNG carburetter and heating, pass through the decompression venting valve voltage-regulation voltage-stabilization again after, use for driving engine.
The invention has the beneficial effects as follows:
1, fuel capacity is big, and continual mileage is long.
2, save the repacking cost.With an effective volume is that 300 liters vehicle-mounted LNG storage tank is an example, and its price is added and installed and the connection expense about 2.6 ten thousand yuan, and its cost is about 30,000 yuan.Directly get gas from the LNG storage tank, each tank car can be saved nearly 30,000 yuan of repacking expense.
3, do not need to build the LNG gas station, save the huge investment of building a station.
4, reduced the extra duty of tank car, and do not taken the available space of tank car, can not impact the safety traffic of vehicle.
Legend and explanation
Directly get the diesel-LNG hybrid fuel LNG tank car gas supply system schematic diagram of gas from the tank car storage tank.1.LNG storage tank .2. low-temperature metal flexible pipe among the figure, 3.LNG carburetter, 4. decompression venting valve.
The specific embodiment
Directly the diesel-LNG hybrid fuel LNG tank car of getting gas from the tank car storage tank is made up of LNG gas supply system and diesel oil-natural gas double-fuel system.
The LNG gas supply system is directly got gas from the LNG storage tank of tank car, and it mainly is made up of LNG storage tank, LNG carburetter, low-temperature metal flexible pipe, decompression venting valve.
The present invention is applied to the LNG tank car, can be implemented in work under full diesel oil state and the diesel-LNG hybrid fuel state, is controlled by electronic commutator.Under full diesel oil working condition, diesel oil-bifuel system cuts off natural fuels by electromagnetic valve, and driving engine returns to former machine mode of operation, and the work energy and the operating characteristic of driving engine are unaffected.Under diesel-LNG hybrid fuel state, after the vaporization of LNG carburetter,, enter engine aspirating system from the LNG of tank car storage tank by the control of diesel gas bifuel system through reducing valve pressure regulation and voltage stabilizing, and enter the engine combustion acting behind the air-blending.
