Abstract

The invention discloses negative pressure drainage equipment of a hydrogen fuel system. The negative pressure drainage equipment of the hydrogen fuel system comprises a high-pressure hydrogen source and an electric pile, and is characterized by further comprising an electric pile reaction route and a hydrogen injection route, wherein the electric pile reaction route comprises the high-pressure hydrogen source, an injector, a heating and humidifying device and the electric pile which are connected in sequence; the hydrogen injection route comprises the electric pile, a water-gas separator and the injector which are connected in sequence; and hydrogen enters the electric pile from the electric pile reaction route to complete chemical reaction, and the residual hydrogen after the reaction is sucked into the electric pile reaction route by the injector from the hydrogen injection route. According to the negative pressure drainage equipment of the hydrogen fuel system provided by the invention, by setting the circulating recovery route, the residual hydrogen in the electric pile returns to the injector through a back pressure device and the water-gas separator, and then participates in a new electric pile chemical reaction along the electric pile reaction route, so that the hydrogen is completely utilized, the waste of resources is avoided, and the use cost is saved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, and more specifically, relates to hydrogen fuel system negative pressure drainage equipment. Background technique [0002] As the concept of green and environmentally friendly life is gradually becoming popular, more and more people are choosing new energy vehicles, especially hydrogen engine vehicles. Since the fuel used by hydrogen engines is gaseous hydrogen, the emissions are pure water, which has infinite Pollution, zero emission, rich reserves and other advantages, hydrogen engine vehicles are a means of transportation that truly achieves zero emissions. However, due to the high price of hydrogen, and in the reactor reaction process, the internal hydrogen cannot be completely reacted, and the effective utilization rate is low, which leads to waste of hydrogen and increases the cost of use. Contents of the invention [0003] The purpose of the present invention is to provide a...
