Multi-stage compressed air silencer and application

Abstract

The invention discloses a multi-stage type compressed air silencer and application, the multi-stage type compressed air silencer comprises a shell and an air inlet pipeline, and at least three continuous cylindrical cavities are formed in the shell in the axial direction; the adjacent chambers are separated by chamber walls and are communicated through a connecting pipeline; the adjacent connecting pipelines are arranged in a staggered mode in the radial direction. One end of the air inlet pipeline extends into the first cavity; in the airflow direction, the chambers are used as a first-stage chamber, a second-stage chamber,... and a final-stage chamber, and an air outlet pipeline is arranged in the final-stage chamber; along the radial direction, the air inlet pipeline and the connecting pipeline for connecting the first-stage chamber and the second-stage chamber are arranged in a staggered manner; the inner diameter of the air inlet pipeline is D, the inner diameters of the first-stage cavity, the second-stage cavity,... and the last-stage cavity are 4-8D, and the depth of the cavity is 6-8D; the inner diameters of the connecting pipeline and the air inlet pipeline are equal; the distance between the end of the air inlet pipeline and the chamber wall of the first-stage chamber opposite to the end of the air inlet pipeline is 1-1.5 D; the distance between the end heads on the two sides of each connecting pipeline and the chamber wall of the corresponding chamber right opposite to the connecting pipeline is 1-1.5 D.

Description

technical field [0001] The invention belongs to the technical field of compressed air, and particularly relates to a multi-stage compressed air muffler with drainage function and its application. Background technique [0002] In the application of compressed air systems, the air compressor equipment compresses the gas during operation, and the gas temperature will rise during the gas compression process. After the high temperature and high pressure gas is cooled, the moisture in the gas will be precipitated, and the precipitated water must be Parts are promptly removed from the gas. Since the pressure of the compressed air increases, the high-pressure gas will be discharged together with the water during the process of discharging water, and high noise will be generated, which will affect the crowd and the production and living environment. [0003] The principle of the muffler is to release the energy in the gas through the sudden change of the cross section and turn it in...
