Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 As shown, a gas venting muffler is composed of a straight inlet pipe 2, a conical expanding pipe 3, a cylinder body 1, a tapered orifice plate 4, a first-stage throttling and pressure-reducing pipe 5, and a second-stage throttling and pressure-reducing pipe 6 , small hole injection pipe 7, resistive sound-absorbing material 8, exhaust elbow 9, drain pipe 10 composition. The inside of the cylinder 1 is sequentially provided with a tapered orifice plate 4, a first-stage throttle and pressure-reducing pipe 5, a second-stage throttle and pressure-reducing pipe 6, and a small hole injection pipe 7. The opening at the bottom of the cylinder 1 is connected with an air intake section. The air intake section is composed of a conical expander pipe 3 and a straight air intake pipe 2. The top opening of the cylinder body 1 is connected wi...

The invention discloses a gas emptying silencer. The gas emptying silencer consists of an intake straight pipe, a conical gradual expanding pipe, a cylinder, a conical hole plate, a first-grade throttling pressure reducing pipe, a second-grade throttling pressure reducing pipe, a small hole injecting pipe, a resistance sound absorbing material, an exhaust bent pipe and a drainage pipe. The conicalhole plate, the first-grade throttling pressure reducing pipe, the second-grade throttling pressure reducing pipe and the small hole injecting pipe are arranged in the cylinder in sequence; a bottomopening of the cylinder is connected with an intake section; the intake section consists of the conical gradual expanding pipe and the intake straight pipe; a top opening of the cylinder is connectedwith the exhaust bent pipe; and one layer of the resistance sound absorbing material is bonded on the inner wall of the exhaust bent pipe. The gas emptying silencer performs the noise reducing treatment on emptied gas passing through the silencer by using such principles as volume expansion speed reduction, throttling pressure reduction, small hole injection and resistance sound absorption, and has the advantages of simple structure, small size, high silencing efficiency and low cost.
Description
technical field [0001] The invention belongs to the technical field of mufflers, and in particular relates to a gas venting muffler. Background technique [0002] Today, with the rapid development of industry and transportation, noise pollution, together with air pollution, water pollution, and waste pollution, is considered to be the four major pollutions in the contemporary world, and has gradually become one of the most important public hazards and a contemporary worldwide problem. , affecting people's normal life and physical and mental health. Among all public hazards, noise pollutes the largest area, and some countries list it as the first of the seven major public hazards. Exhaust venting noise is a common source of noise in industry, from boiler exhaust in thermal power plants to blast furnace venting in iron and steel enterprises, process gas release in chemical plants, exhaust from air compressors, jet aircraft, rocket launches, etc. , will produce strong radiati...
