The invention discloses a filter element for filtering hydrogen gas. The filter element comprises a filter element barrel body, wherein an exhausting opening is formed in one end of the filter elementbarrel body; the exhausting opening is communicated with an inner cavity of the filter element barrel body; a gas inlet head is arranged at the other end of the filter element barrel body; a gas inlet hole is formed in the outer end of the gas inlet head; a plurality of exhausting through holes are formed in a side wall of the gas inlet head at intervals; each exhausting through hole is communicated with the gas inlet hole; filtering wires are wound on a barrel wall of the filter element barrel body; a filtering gap is formed by a gap between the adjacent filtering wires; a plurality of gas inlet grooves which are inward concave are formed in a barrel wall of the filter element barrel body wound by the filtering wires at intervals along the peripheral direction; a plurality of filter element through holes are formed in each gas inlet groove; each filter element through hole is communicated with the inner cavity of the filter element barrel body. The filter element disclosed by the invention has the advantages of simple structure and small occupied space; the filter element can be directly mounted in a valve body of hydrogenation equipment, so that the hydrogen gas is effectively filtered and the cleanliness of the hydrogen gas is ensured, and furthermore, the quality of hydrogen energy sources can be effectively improved and a condition that a vehicle-mounted gas bottle valveis blocked is prevented.
Description
technical field [0001] The invention relates to the technical field of filter elements, in particular to a filter element for filtering hydrogen. Background technique [0002] At present, during the long-term storage of hydrogen, impurities will be mixed due to micro-leakage and other reasons. If the mixed impurities are directly filled into the vehicle gas cylinder, it will cause valve blockage and other failures over time. Therefore, it is necessary to filter the hydrogen before filling to ensure the purity of the hydrogen. Contents of the invention [0003] The purpose of the present invention is to provide a hydrogen filter element, which can be used to filter hydrogen, so as to ensure the purity of hydrogen. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a hydrogen filter element, comprising: a filter element cylinder, one end of the filter element cylinder is provided with an exhaust port, the exhaust port ...
