Description
Technical field
The present invention relates to a kind of silencer, particularly a kind of displacement self compensation gas-discharging silencer.
Background technique
Existing gas-discharging silencer is mainly used in discharging sky of steam on all kinds of steam heating power apparatus and process such as boiler, steam turbine in the industrial fields such as electric power, oil, chemical industry, metallurgy, weaving.Because vapor pressure, the temperature of discharge are all higher, discharge at emptying pipe end (being unkitted silencing apparatus) steam energy the enormous impact power, expansive force etc. that produce to mix with the atmospheric turbulence in space and produce intense noise, the severe exacerbation human settlement of plant area and periphery.For this reason, various forms denoising device (exhaust silencer) must be installed additional at blow-off line end, suppress, shift, absorb unnecessary noise, make it the requirement reached in environmental protection.
Gas-discharging silencer must correctly be installed before use, it utilizes self ear seat and steel structure body (boiler room girder steel, frame, workshop wall etc.) be rigidly connected by fastening piece formation, steam directly enters in air after flowing into muffler body dilatation step-down by blow-off line, the steam discharged is mostly High Temperature High Pressure overheated (saturated) gas, the material that blow-off line uses mostly is Fine Steel Casting iron pipe or High Strength Low Alloy Steel pipe, and blow-off line is longer, whole piping will produce very large displacement in the above operating condition, displacement compensation device must be provided with like this between silencing apparatus and blow-off line, absorb piping level, thermal walking on vertical direction, piping is made not to be subject to additional load because of the installation of silencing apparatus, ensure the Security of blow-off line under heat energy work, simultaneously by outside the hydrophobic timely escape piping that produces during steam discharge.The miscellaneous assembly of pipeline---blow-off line drainage plate during this displacement compensation device is all selected " thermal power plant steam-water pipe component modular design ", it utilizes the bascule between upper dish and lower wall to solve the thermal walking problem of pipeline.But in many engineering practice, finding the cases such as the production accident of inconvenience and the initiation produced on Pipe installing because using drainage plate parts, summing up reason as follows:
1, drainage plate is as the annex of gas-discharging silencer, and structure is upper and lower two-part compositions, and volume is little, seems very scattered, and in transport and management process, because it is not assembled into an entirety with silencing apparatus, therefore very easily one integral piece or part are lost.
2, owing to arranging drainage plate between gas-discharging silencer and blow-off line, pipeline middle joint place weld bond quantity will be made to increase, this just make pipeline stay leakage may and safety on hidden danger, turn increase difficulty and the workload of engineering site installation.
3, because piping in whole exhaust steam pipeline moves towards complicated layout, pipe fitting more (threeway, elbow, reducing adapter etc.), piping equivalent length, resistance damage etc. can not provide exact value, for drainage plate design, select and bring congenital initial condition not enough, occurred that a lot of exhaust steam pipeline produces a large amount of steam and regurgitates and the production accident such as drainage plate explosion from two ligaments because arranging drainage plate.
