Water separator suitable for hydrogen fuel cell hydrogen tail gas circulation system

Abstract

The invention discloses a water separator suitable for a hydrogen fuel cell hydrogen tail gas circulation system, which comprises an upper cover, a canister and a lower cover, wherein the upper end and the lower end of the canister are respectively connected with the lower end of the upper cover and the upper end of the lower cover; in the middle of the canister, a baffle connected with the innerwall of the canister in a surrounding mode separates the inner cavity of the canister into an upper separation cavity and a lower liquid storage cavity, and the place, close to the inner wall of the canister, of the baffle is provided with a circle of through holes; an intake pipe tangentially enters the separation cavity of the canister along the circumference of the side wall of the canister; the upper end of a central pipe with a vertical central axis is located below the upper cover, and the lower end of the central pipe is connected with the top of the baffle; each of an outlet pipe and abypass pipe arranged on the side wall of the canister extends to the inner part of the canister and is communicated with the lower end of the central pipe; and the lowest portion of the inner cavityof the lower cover is communicated with a drain pipe. The structure is compact, the operation is reliable, the separation efficiency is moderate, and the operation requirements of the hydrogen fuel cell are met.

Description

technical field [0001] The invention relates to a water separator suitable for a hydrogen tail gas circulation system of a hydrogen fuel cell. Background technique [0002] It has become a trend for new energy vehicles to replace traditional fuel vehicles, especially with the support of relevant policies and funds from national government departments, this trend is developing rapidly. Many manufacturers have launched new energy vehicle research and development projects and invested a lot of manpower and funds. As an alternative energy source for fuel vehicles, hydrogen fuel cells have also attracted the attention of many manufacturers at home and abroad. Especially in China, the research and development of hydrogen fuel cell vehicles is increasing day by day, and the speed of progress is also amazing. [0003] In the actual operation of hydrogen fuel cells, due to the humidification of water and the presence of water in the reaction products, the water will inevitably be di...

Problems solved by technology

The water in the hydrogen tail gas will increase the workload of the hydrogen circulation pump, and even cause the hydrogen circulation pump to work poorly. At the same time, the water in the hydrogen tail gas will continue to accumulate, which will block the hydrogen channel of the battery in severe cases and cause poor battery operation.
