Abstract

The invention discloses a quick detecting device for arsenic element in natural gas. The quick detecting device comprises a gas carrying device, an absorption liquid carrying device and a power device, wherein the gas carrying device is used for carrying to-be-detected natural gas; the absorption liquid carrying device comprises one adsorption device or multiple adsorption devices, air inlets and air outlets are formed in the adsorption devices, and the multiple adsorption devices are connected in series and are internally filled with adsorbing agents; the power device is connected between the gas carrying device and one air inlet in the absorption liquid carrying device, and the power device is used for pumping the natural gas in the gas carrying device in the absorption liquid carrying device for being adsorbed by the adsorbing agents. The quick detecting device for the arsenic element in the natural gas, disclosed by the invention, is simple, the cost of used adsorbing agents is low, quick treatment and detection of a natural gas site can be met, the carry is convenient, the cost is lower, and the quick detecting device can be put into use on a large scale.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a rapid detection device for arsenic in natural gas. Background technique [0002] Volatile arsenic compounds in natural gas can significantly shorten the service life of circulating catalysts in the natural gas treatment process, cause blockage of natural gas pipelines, and pose a threat to the environment and human health when used. As an important part of the quality inspection of natural gas products, the detection technology of arsenic content in natural gas needs to be broken through urgently. Clarifying the occurrence state of arsenic in natural gas and comprehensively considering the trace and toxicity of arsenic in natural gas are the difficulties that this technology needs to overcome. At the same time, the cost of the selected adsorbent, the simplicity of the experimental device and the selection of experimental testing instruments are also important considerati...
