Double-stacking type LNG gas supply device

Abstract

The invention discloses a double-stacking type LNG gas supply device comprising a frame assembly. Two LNG gas cylinders are arranged in the frame assembly in an upper layer and a lower layer in an overlapped mode. The gas inlet end of the LNG gas cylinders is provided with a gas cylinder gas inlet and outlet pipeline assembly. The gas cylinder gas inlet and outlet pipeline assembly comprises a liquid inlet pipeline, a liquid outlet pipeline, a pressurizing pipeline, a gas return pipeline and a gas exhaust pipeline. A haunching instrument desk matched with the gas cylinder gas inlet and outletpipeline assembly is arranged at the bottom of one side of the frame assembly, and a gas return base, a pressure regulating base, a gas filling socket and a gas filling cylinder pressure gauge base are sequentially arranged on the haunching instrument desk. The air return pipeline is communicated with the air return base; the liquid inlet pipeline is communicated with the gas filling socket; a buffer tank is arranged on the frame assembly at the other end of the LNG gas cylinders, and an evaporator is arranged on the lower side of the lower-layer LNG gas cylinder. According to the fine arrangement, the arrangement is fine, safety and reliability are achieved, space is saved, the stacking mode is adopted, energy storage of the gas supply device can be increased and the requirement for the endurance mileage of the vehicle type can be met.

Description

technical field [0001] The invention relates to an LNG gas supply device for clean energy commercial vehicles, in particular to a double-stacked LNG gas supply device. Background technique [0002] The LNG model is a new strategic model, which is different from the traditional fuel drive and lithium battery electric drive. This LNG model uses natural gas as the fuel for the engine, which is consistent with the national clean energy strategy goal. It has pollution-free, safe and reliable, and easy to operate. Features to meet the requirements of the vehicle. After the use of traditional fuel engine models, a lot of harmful gases such as nitric oxide will be produced, which not only pollutes the air, but also has a relatively large impact on the living environment of human beings. During the use of lithium batteries, not only worry about the impact of high-voltage electricity on the safety of use, but also the long-term charging wait will also cause users to lose part of thei...
