Description
Technical field
The present invention relates to boiler noise reducing apparatus field, more particularly to a kind of pipe blowing silencer.
Background technology
With the rapid development of power industry, station boiler unit continues to increase, and 300-1000MW units will turn into the present
Main force's unit afterwards.Installation or restorative maintenance are completed in thermal power generation unit, before putting into operation, is passed through in order to ensure the safety of unit
Ji operation, it is necessary to carry out steam-line blowing to remove scale inside superheater and reheater system pipeline, welding slag and other miscellaneous
The industrial refuses such as thing, thoroughly to remove the debris in piping, blowpipe is often even up to a hundred time up to tens times, and take several days or
The longer time.During blowpipe, powerful steam turbulence noise is that high velocity air sprays from the mouth of pipe, impacts and shears surrounding static
Air, cause violent gas disturbance near spout and the very high air power noise of caused sound level, caused noise
Value be up to 130dB (A) and more than, unit capacity it is bigger caused by air power noise it is bigger, its injection noise is continuous
Middle high wideband noise, life, the working and learning of surrounding are severely impacted, particularly the physical and mental health of people are caused seriously to endanger
Evil.
Critical noisy caused by order to eliminate unit blowpipe endangers, it is necessary to installs pipe blowing silencer additional in blowpipe pipe end.
Can look at for pipe blowing silencer be pipeline a part, after internally making Acoustic treatment, the production of noise can be weakened
Raw and propagation, it is to solve effective noise reducing apparatus that above-mentioned unit blowpipe causes critical noisy to endanger.
Blowpipe pipeline is complicated, and the determination for making steam parameter in its pipe-line system is a challenge, is steamed in addition in pipeline
Steam flow speed is very high, and high speed steam flow is mingled with the industrial refuses such as a large amount of scales, welding slag and other debris, to reach certain noise reduction effect
Fruit, design and making to silencer are very high.
Although current existing silencer can be with noise reduction, its noise reduction is less desirable, and can not observe it
Noise reduction situation, in clashing for various industrial refuses, self structure absorbs the problem of expanding with heat and contract with cold brought under high temperature, causes
Silencer deformation even damages, and service life is short.
The content of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, there is provided a kind of observable, multistage sound-deadening and noise-reducing with
And the pipe blowing silencer of service life length.
The technical solution adopted by the present invention is as follows：
Pipe blowing silencer, including muffler shell, the left end of muffler shell are provided with entrance sleeve, the lower section of entrance sleeve
Provided with impurities removal peep hole, the right-hand member of muffler shell is provided with end socket, and end socket has supervisor's impurity discharging port, muffler shell bottom two
End is provided with bearing, and silencer impurity discharging port and discharge outlet are provided among muffler shell bottom；Anechoic chamber is provided with muffler shell,
Muffler shell top is provided with upper cover plate.
Further, in order to bear clashing for various industrial refuses, muffler shell, which is provided with, strengthens channel-section steel.
Further, for more effective noise reduction, muffler shell is interior to be provided with three anechoic chambers.
Further, muffler shell is provided with reinforced support.
Further, four, muffler shell top drift angle is provided with hanger.
The invention has the advantages that：
1. the present invention can carry out clearing up the debris of anechoic chamber by impurities removal peep hole, effectively remove debris, convenient next time
Reuse, realize more preferable noise reduction；
2. the present invention is using three anechoic chambers successively noise reduction, sound deadening capacity is big, and noise reduction is up to 30dB~45dB；
3. using channel-section steel and reinforced support is strengthened, silencer can bear clashing for various industrial refuses, and smoothly arrange
Go out, under severe operating conditions also can normal work, and do not influence the steam flow of blowpipe, service life length；
4. the bearing of suppressor case and there are enough rigidity and intensity, acoustic wave filter structure design with the connection member of housing
It itself can bear exhaust counterforce, heat expansion thrust and carry the various additional forces such as vibration force caused by the high speed steam flow of debris secretly.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is top view of the present invention.
Fig. 3 is the left view of the present invention.
Embodiment
The present invention is described further below in conjunction with the accompanying drawings：
As shown in Figure 1,2 and 3, pipe blowing silencer, including muffler shell 3, the left end of muffler shell 3 connect provided with import
Pipe 1, the lower section of entrance sleeve 1 are provided with impurities removal peep hole 12, and the right-hand member of muffler shell 3 is provided with end socket 5, and end socket 5 has master
Pipe impurity discharging port 6, the bottom both ends of muffler shell 3 are provided with bearing 9, the He of silencer impurity discharging port 8 are provided among the bottom of muffler shell 3
Discharge outlet 7；Anechoic chamber 10 is provided with muffler shell 3, the top of muffler shell 3 is provided with upper cover plate 13；Set on muffler shell 3
Have and strengthen channel-section steel 4；Three anechoic chambers 10 are provided with muffler shell；Muffler shell 3 is provided with reinforced support 11；Outside silencer
Four, 3 top of shell drift angle is provided with hanger 2.
Embodiment：
Pipe blowing silencer is typically mounted at outdoor opening, and entrance sleeve 1 docks with carrying out steam pipe, and silencer bearing 9 is flat
It is put on the pre-cast concrete of level land, bearing 9 and platform are typically not required to force to fix, and can allow silencer free wxpansion, can also disappear
Sound device top corner is fixed on surrounding earth anchor or balancing weight with pulley.
After each use of silencer, it is necessary to internal debris is cleaned out, particularly should to the debris in main pipeline circular hole
Remove, the debris in outer layer anechoic chamber can be cleared up by impurities removal peep hole 12 with small class instrument of taking off, the debris on the hole of anechoic chamber 10
Also must clear up, so that next time uses safely.
After each use of silencer, silencer band end socket 5 end can be raised, being catchmented inside such silencer can be by discharge outlet
Discharge, debris can also be removed, and shell must carry out antirust paint processing such as long-term stop transport.
The foregoing is only a specific embodiment of the invention, but the protection domain invented is not limited thereto, any ripe
Know those skilled in the art the invention discloses technical scope in, the change or replacement that can readily occur in should all be covered
Within the protection domain of invention.
