The invention provides an adsorption type natural gas filtering device. The device comprises at least one pressure container combined in a clustering manner, wherein the at least one pressure container is sealed, filtering materials are arranged in the pressure container, a gas inlet and a gas outlet are formed in the pressure container, the gas inlet of the pressure container is connected with a natural gas output device through a pipeline, and the gas outlet of the pressure container is externally arranged on an adsorption type natural gas storage device through a pipeline; valve groups are arranged on the pipelines. The at least one pressure container combined in a clustering manner is adopted and filled with different filtering materials, the filtering device can be rapidly replaced, the manufacture difficulty and the difficulty in operation and maintenance under the actual work condition are reduced, and the at least one pressure container is independent or connected in parallel/in series to a gas charge-discharge pipeline as required; abnormal work of the pipeline and equipment in the natural gas unloading process is avoided, the adsorption capability and the use rate of storage equipment are improved through rapid replacement of adsorption materials for adsorbing natural gas, and besides, the maintenance cost is reduced.
