Background

With the increasing living standard of people, the role of natural gas in the life of people is more and more important. The number of pipelines is also increasing as the primary carrier of natural gas. However, during the pipeline transportation process, when the natural gas flows through the compressor, the elbow, the valve and other parts, the motion state can be suddenly changed, and strong noise can be generated in the process, so that the working environment is seriously affected. Muffling devices are often installed in the compressors or in the intake and exhaust systems of the pipeline to reduce the noise of the natural gas flowing through these devices. At present, most of silencers in the market do not have a filtering function, and impurities carried in natural gas easily block small holes in the silencers, so that the noise reduction effect of the silencers is poor.

The collecting pipe consists of a circular plate with the thickness kept unchanged and a small circular pipe penetrating through the circular plate, and the inlet and the outlet of the small circular pipe are both inwards concave.

The natural gas enters the silencing device from the gas inlet pipe, and when the natural gas passes through the rectifying layer, the gas is rapidly diffused from the center to the edge due to the blocking effect of the rectifying layer on the gas flow, and then enters the filter plate through the circular flow channel in the rectifying layer. The natural gas both can pass through also can pass through filtering material from the filter flow channel, and at this in-process, gas can collide with filtering material, and the impurity of carrying also can be adsorbed by filtering material. After impurities are removed by the filter plate, natural gas enters the silencing chamber on the silencing plate, the gas expands in the silencing chamber and collides with the silencing balls, so that energy carried by the gas is reduced, and meanwhile, silencing cotton on the surfaces of the silencing balls can absorb noise generated by the natural gas. After the natural gas passes through the silencing cavity, the natural gas enters the collecting pipe, the disturbance of the natural gas can be reduced by the collecting pipe, and finally the natural gas is discharged through the exhaust pipe.
