Abstract
The invention discloses a pipe blowing silencer. The pipe blowing silencer comprises a silencer shell, wherein an inlet connection tube is arranged at the left end of the silencer shell; a debris discharge observation hole is formed below the inlet connection tube; the right end of the silencer shell is provided with a shell cover; a main pipe debris discharge opening is arranged below the shell cover; two ends of the bottom of the silencer shell are provided with pedestals; silencer debris discharge openings and water drainage ports are arranged at the middle part of the bottom of the silencer shell; silencing chambers are arranged in the silencer shell; and an upper cover plate is arranged on the upper part of the silencer shell. According to the pipe blowing silencer, debris in the silencing chambers can be cleaned through the debris discharge observation hole; the debris can be effectively removed; and reusing of the next time is facilitated, so that noise reduction can be realized better.
Description
Technical field
The present invention relates to boiler noise reducing apparatus field, particularly relate to a kind of pipe blowing silencer.
Background technique
Along with the develop rapidly of power industry, continuing to increase of station boiler unit, 300-1000MW unit will become main force's unit from now on.Installation or restorative maintenance is completed at thermal power generation unit; before putting into operation; in order to ensure the safety and economic operation of unit; steam-line blowing must be carried out to remove scale, the industrial refuse such as welding slag and other foreign material of superheater and reheater system pipeline inside; for thoroughly removing the foreign material in piping; blowpipe number of times reaches tens times even up to a hundred times, and continues the time of several days or longer.During blowpipe, powerful steam turbulence noise is that high velocity air sprays from the mouth of pipe, impact and shear the air of surrounding static, cause gas disturbance violent near spout and the very high air power noise of the sound level produced, produce noise figure up to 130dB (A) and more than, the air power noise of the larger generation of unit capacity is larger, its injection noise is high wideband noise in continuous print, seriously affect the life of surrounding, working and learning, particularly serious harm is caused to the physical and mental health of people.
In order to eliminate the critical noisy harm that unit blowpipe causes, pipe blowing silencer must be installed additional at blowpipe pipe end.Can look at for pipe blowing silencer is a constituent element of pipeline, after Acoustic treatment is made in inside, can weaken generation and the propagation of noise, is to solve effective noise reducing apparatus that above-mentioned unit blowpipe causes critical noisy to endanger.
Blowpipe pipeline is complicated, the determination of steam parameter in its pipe-line system is made to be a challenge, in addition in pipeline, steam flow rate is very high, and high speed steam flow is mingled with the industrial refuses such as a large amount of scale, welding slag and other foreign material, reaching certain noise reduction, is very high to the designing and making of silencing apparatus.
Although current existing silencing apparatus can noise reduction, its noise reduction is not very desirable, and cannot observe its noise reduction situation, clashing of various industrial refuse, problem that what self structure was brought under absorbing high temperature expand with heat and contract with cold, cause silencing apparatus to be out of shape and even damage, working life is short.
Summary of the invention
The problems referred to above that object of the present invention exists for prior art, provide the pipe blowing silencer of a kind of observable, multistage sound-deadening and noise-reducing and long service life.
The technical solution used in the present invention is as follows:
---pipe blowing silencer, comprise muffler shell, the left end of muffler shell is provided with entrance sleeve, the below of entrance sleeve is provided with impurities removal peep hole, the right-hand member of muffler shell is provided with end socket, end socket has supervisor's impurity discharging port, and bottom muffler shell, two ends are provided with bearing, is provided with silencing apparatus impurity discharging port and drain opening in the middle of bottom muffler shell; Be provided with anechoic chamber in muffler shell, muffler shell top is provided with upper cover plate.
Further, in order to bear clashing of various industrial refuse, muffler shell is provided with reinforcement channel-section steel.
Further, in order to more effective noise reduction, in muffler shell, be provided with three anechoic chambers.
Further, muffler shell is provided with reinforcing bracket.
Further, four, muffler shell top drift angle is provided with hanger.
The present invention has following beneficial effect:
1. the present invention can carry out by impurities removal peep hole the foreign material clearing up anechoic chamber, effectively removes foreign material, facilitates reuse next time, realize better noise reduction;
2. the present invention adopts three anechoic chamber's noise reductions successively, and sound deadening capacity is large, and noise reduction can reach 30dB ~ 45dB;
3. adopt and strengthen channel-section steel and reinforcing bracket, silencing apparatus can bear clashing of various industrial refuse, and discharges smoothly, also can normally work under severe operating conditions, and does not affect the steam flow of blowpipe, long service life;
4. suppressor case bearing and and the connected element of housing have enough Rigidity and strengths, acoustic wave filter structure design self can bear the various additional forces such as the vibration force that exhaust counterforce, heat expansion thrust and the high speed steam flow of carrying foreign material secretly cause.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is plan view of the present invention.
Fig. 3 is left view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1,2 and 3, pipe blowing silencer, comprise muffler shell 3, the left end of muffler shell 3 is provided with entrance sleeve 1, the below of entrance sleeve 1 is 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 supervisor's impurity discharging port 6, bottom muffler shell 3, two ends are provided with bearing 9, are provided with silencing apparatus impurity discharging port 8 and drain opening 7 in the middle of bottom muffler shell 3; Be provided with anechoic chamber 10 in muffler shell 3, muffler shell 3 top is provided with upper cover plate 13; Muffler shell 3 is provided with strengthens channel-section steel 4; Three anechoic chambers 10 are provided with in muffler shell; Muffler shell 3 is provided with reinforcing bracket 11; Four, muffler shell 3 top drift angle is provided with hanger 2.
Embodiment:
