1.Overview and use of the Dissolving acetylene Equipment The produced Acetylene gas is compressed and dissolved in the solvent usually acetone, which is contained in the cylinder with porous packing .The acetylene gas is called dissolved acetylene and can be released from acetone when being needed. The dissolved acetylene can be stored safely, transported and used conveniently. The dissolved acetylene is widely used in illumination, welding, cutting and different kinds of flame processing to meet the requirements of scientific research and constructions. As a new kind of technology that being developed and disseminated greatly, the :dissolved acetylene ,technique has been playing a very important role in China economy. 2.Main Technical Performance: ModelDA-20 typeCapacity(According to four-stage, water enter into it at 30degree calculate) 20m3/hPurity≤98%Outlet pressure of the generator4-4.5KPaTemperature of the generator≤65degreeCalcium carbide particle size8-200mmFilling pressure2.45MPaWater consumption2t/h
