Combined gas and water separating device

Abstract

The invention provides a combined gas and water separating device. The device comprises a housing which is provided with an opening in the upper part and a water draining port in the lower part, a solenoid valve which is mounted on the water draining port, a gas outlet and a volute gas inlet which cover the opening in the upper part of the housing and are independent from each other, an upper cover of a volute rotating chamber which is connected to the volute gas inlet, a sleeve which is coaxially positioned in the housing and is mounted on an upper cover in a manner of communicating with thegas outlet, and a filter element which is mounted at the lower part of the sleeve and is coaxial with the housing. The device integrates the functions of a cyclone separator and a filter element filter; flow guide blades are saved; and the device has the beneficial effects of being small in structure, small in pressure reduction, good in water separating effect, and flexible to mount.

Description

technical field [0001] The invention relates to an automobile power system, and relates to a combined gas-water separation device. Background technique [0002] At present, my country's fuel cell vehicle-related system technology and industrial chain are not yet mature, and various components need to be developed and optimized. In the fuel cell system, the metering ratio of the supplied hydrogen is greater than 1, and the unreacted hydrogen forms a circulating gas circuit. The closed cycle makes the liquid water produced by the fuel cell stack reaction exist in the pipeline, which needs to be discharged regularly. Therefore, in the fuel cell system, it is necessary to use a compact structure, a certain water storage capacity, and an efficient gas-water separator to separate the liquid water in the pipeline, so as to ensure the high performance of the fuel cell.

AI Technical Summary

Problems solved by technology

[0003] Existing air-water separators for vehicles mainly use filter elements to filter, referring to the air-water separators used in air compressors. Guide vanes are installed on the top of the filter elements, but the flow-guiding effect of the guide vanes is very limited and cannot form sufficient Swirling gas flow facilitates separation of liquid droplets from gas

And under different working conditions, when the gas flow rate is changed, especially when the gas flow rate is increased, the separation effect is unstable or reduced, so that there is still a certain amount of liquid water in the hydrogen pipeline, which affects the working performance of the fuel cell stack
