Description

Front pretreatment device for magnetic oxygen analyzer Technical Field The utility model relates to the technical field of gas pretreatment devices, in particular to a pre-treatment device for a magneto-oxygen analyzer. Background At present, carbon black removal on a device for preparing acetylene from natural gas is a complex and difficult work, most of water washing methods in the prior art are common, and the structure of a pre-stage pretreatment system is basically composed of components such as a Y-shaped sampler, a jet valve, a water washing tank, a gas-liquid separation tank, an exquisite filter and the like. The working principle of the pre-pretreatment of the magnetic oxygen analyzer is that the gas sampled by a Y-shaped sampler of a sampling root valve passes through a gas-liquid separator, is washed by a jet valve and enters a water washing tank (the water washing tank plays a role in dehydration), and the gas directly enters an analysis instrument after coming out of the water washing tank through an exquisite filter. Because the carbon black is insoluble in water, the Y-shaped sampler of the sampling root valve is flushed with desalted water, the carbon black in the sample gas cannot be effectively removed, and the desalted water is ejected through the jet valve, so that the analysis data of the magneto-oxygen analyzer is higher due to the fact that the water possibly contains bubbles, and meanwhile, once the sample gas is seriously carried with water, the risk of damaging the analyzer exists, and the problem of how to efficiently remove the carbon black in the sample gas to reduce the water becomes the urgent problem to be solved by the technicians in the field.
