Abstract

A self adapting humidifying equipment for fuel cell engine is primarily consisted of water tank, water level controller, solenoid valve, venturi and current limiting loop, in which the water level controller and the solenoid valve are connected with the water tank, while the current limiting loop is connected with the water tank and the venturi. The present invention utilizes the transformation relation between total pressure, kinetic pressure and static pressure of fluid body in the venturi, and controls humidification flow with pressure difference, in view of the relationship between the humidification quantity and airflow discharge is linear, thus ensures a constant specific humidity for humidified gas. The present invention provides a simple structure, and is easy to be used, maintained and repaired.

Description

technical field [0001] The invention relates to a humidifying device, especially for a fuel cell engine, which can self-adaptively adjust the humidification amount under changing working conditions. Background technique [0002] Hydrogen-oxygen fuel cell engine technology is an environmentally friendly and non-polluting new energy technology. At present, some developed countries in the world are competing to study this topic. Many technical details are kept in a highly confidential state. Although some documents can be found or retrieved Some patent documents, but they all belong to the idea of ​​technical solutions in the early stage of technology development, and have not found relevant documents and patent documents related to preliminary design, detailed design, that is, the realization of engineering system technical solutions and specific engineering structures, and there are very few references. , for example, from the patent documents that have been consulted, there ...
