Description

A kind of squeezer muffling device

Technical field

The utility model is related to high-temperature gas noise reduction technical field more particularly to a kind of squeezer muffling devices.

Background technology

It is well known that can all be used as squeezer in fields such as chemical industry, oil, light industry, water process, plating, metallurgy Equipment, and in the industrial production, a large amount of high-temperature gas is often will produce, is all directly to pass through high-temperature gas under normal circumstances Exhaust pipe is discharged.Although having saved certain cost in this way, there is a great defects：Exhaust pipe can be by High Temperature Gas The impact vibration of body and generate the higher noise of sound level, the living environment of working environment and surrounding near contaminated equipment.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of squeezer muffling devices, to solve squeezer discharge High-temperature gas caused by noise problem.

Technical solution adopted by the utility model to solve its technical problems is：A kind of squeezer muffling device, including it is outer Shell, spiral plate, air inlet pipe, primary muffler, exhaust pipe, described primary muffler one end are connected with air inlet pipe, the other end with it is outer Shell phase connects, and is provided with meander cylinder in primary muffler, is provided with multiple gas vents on the meander cylinder, exhaust is provided in shell Pipe, exhaust pipe form an annular space with shell, spiral plate, spiral plate one end and shell are provided in annular space Inner wall is fixedly connected, and the other end is fixedly connected with exhaust tube wall, and outer casing bottom is provided with drain valve, the connection of drain valve bottom Drainpipe.

Further, the primary muffler is arranged along shell tangential direction.

Further, the shell is conical structure.

Further, the gas vent aperture is 5-10mm.

Further, described spiral plate one end seals and is fixedly connected with outer casing inner wall, and the other end is close with exhaust tube wall It seals and is fixedly connected.

The utility model has the beneficial effects that：By the setting of primary muffler, make the flow path of high-temperature gas more Complications play the effect for disperseing certain dispersed sound waves energy.It is gas in shell by the way that spiral plate is arranged after gas enters shell Body helical flow extends the path of gas spiral flowing, and the path of spiral decreases impact force of the air-flow to shell, noise Energy also can centainly be decayed in spiral path, and then play the role of noise reduction, reduce noise to surrounding working environment It influences.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model；

Shown in Fig. 1：1- shells, 2- spiral plates, 3- exhaust pipes, 4- drainpipes, 5- meander cylinders, 6- primary mufflers, 7- Air inlet pipe, 8- drain valves.

Specific implementation mode

The utility model is further illustrated with reference to the accompanying drawings and examples.

As shown in Figure 1, a kind of squeezer muffling device, includes mainly shell 1, spiral plate 2, air inlet pipe 7, primary muffler 6, exhaust pipe 3,6 one end of the primary muffler are connected with air inlet pipe 7, and the other end is connected with shell 1, is set in primary muffler 6 It is equipped with meander cylinder 5, multiple gas vents are provided on the meander cylinder 5, exhaust pipe 3, exhaust pipe 3 and shell 1 are provided in shell 1 An annular space is formed, spiral plate 2 is provided in annular space, spiral plate one end is fixedly connected with outer casing inner wall, The other end is fixedly connected with exhaust tube wall, 1 bottom of shell is provided with drain valve 8,8 bottom of drain valve connects drainpipe 4.

High-temperature gas is entered by air inlet pipe 7 in primary muffler 6 first, due to being provided with song in primary muffler 6 Flow cartridge 5, meander cylinder 5 keep the flowing of the gas in primary muffler 6 tortuous, reduce the flow rate of gas and make the flowing road of gas Diameter lengthens, and plays the role of primary noise reduction, and the gas vent being arranged on cylinder 5 of meandering also has further dispersed sound waves energy, The gas come out from primary muffler 6 enters in shell 1, is circulated in shell 1 along spiral plate 2, gas is made to exist Flow path in shell 1 greatly increases, and reduces impact of the gas to shell 1, theoretically for sound source, often increases apart from it Twice, noise just declines 6dB, therefore the setting of spiral plate 2 can effectively reduce noise caused by high-temperature gas.Due to entering Gas temperature in shell 1 is higher, therefore understands some vapor after being contacted with shell 1 and spiral plate 2 and form liquid to the cold Water is provided with drain valve 8 and drainpipe 4 in the bottom of shell 1, the liquid water of formation can be discharged, other gases then pass through Exhaust pipe 3 is discharged from top.

Due to the high-temperature gas speed having just enter into, in order to reduce impact of the gas to shell 1, in order to avoid cause additional Noise, it is preferred that the primary muffler 6 is arranged along 1 tangential direction of shell, and what such gas can be smooth enters shell 1 It is interior, and then generate and circulate.

Shell 1 can be designed to different shapes, and such as cylindrical or rectangular, due to the presence of pressure chamber, gas is through small Cyclone phenomenon is formed when hole is flowed out inside pressure chamber, leads to aperture near exit pressure reduction, as preferred embodiment, The shell 1 is conical structure.

Gas vent can generate certain influence to the flowing of gas, windage can be caused excessive if gas vent is too small, if Gas vent aperture is excessive, is unable to reach the effect of dispersed sound waves energy, as preferred embodiment, the gas vent aperture For 5-10mm.

If the spiral plate 2 being arranged between shell 1 and exhaust pipe 3 and shell 1 and exhaust pipe 3 there are certain interval, It can lead to gas crossfire, generate noise, water conservancy diversion effect is also poor, is happened in order to avoid such, implements as preferred Mode, described spiral plate one end seal and are fixedly connected with outer casing inner wall, and the other end is sealed and is fixedly connected with exhaust tube wall.
