Abstract
The utility model relates to an exhaust silencer for a steam boiler whose main body is a cylinder-shaped silencing tube whose side walls are provided with exhaust holes. The utility model is mainly characterized in that the silencing tube is sleeve tubes with a plurality of layers; the circle cross sections of each sleeve tube is concentric; the lower end of the sleeve tube with an innermost layer is provided with a flat plate with a plurality of holes; steam flow from the steam source which flows through the flat plate with a plurality of holes enters into the sleeve tube with an innermost layer and enters into the sleeve tube with a second layer through the exhaust holes on the side walls of the sleeve tube; Thus, the silencing effect of a plurality of stages is achieved. The utility model is particularly suitable for exhaust and noise reduction of a steam boiler of 3.9-16.9 Mpa, and the noise can be reduced to 60dB; the utility model is also suitable for exhaust and noise reduction of other middle and high pressure air.
Description
The utility model belongs to reduction noise device.
During thermal power plant steam boiler steam discharge, follow and send powerful noise, seriously jeopardize health of people.In order to lower this noise, generally be serial connection one muffler on the gland steam exhauster of steam boiler.The steam flow muffler that uses mostly is the individual layer cylinder mode at present, and its main body is a cylindrical hush pipe, many steam vents are distributing on this sidewall, total relieving capacity is pressed 30% design of boiler capacity, and this tube is gone up termination one convex head, and dock with the boiler steam discharge mouth of pipe lower end.In the middle of, after the high pressure steam flow enters hush pipe, the exhaust hole from the tube sidewall is discharged again, has reduced the steam discharge noise.Because this muffler is the individual layer cylinder mode, steam flow is only through once decompression, and still about 130dB, the effect that reduces noise is undesirable for noise reduction, event discharge of steam noise.
The purpose of this utility model is, a kind of drum type brake muffler is provided, and thermal power plant's steam boiler steam discharge noise is reduced to about 60dB.
Steam boiler exhaust muffler of the present utility model, main body is cylindrical hush pipe, the major technology characteristics are, described hush pipe is the multilayer sleeve, the sidewall of every layer of sleeve is all established many exhaust holes, its exhaust capacity is the 40-60% of boiler capacity, the circular cross section of each sleeve is concentric, an end socket is put in innermost layer sleeve upper end, a plane porous plate is established in the lower end, connect a short tube below this plane porous plate, another termination one flange of this short tube is used for docking with the steam boiler gland steam exhauster, end socket is all established at each outer layer sleeve two ends, the lower end end socket is separately fixed on the innermost layer sleeve wall, and the end socket cantilever of upper end is in sodium fire grate steam pipe, high steam enters the innermost layer sleeve by above-mentioned plane porous plate, the back enters second layer sleeve by the exhaust hole on this sidewall, exhaust hole on this sleeve lateral wall enters the 3rd layer of sleeve again, and the rest may be inferred, and above-mentioned this structure obviously can centering, high steam carries out repeatedly step-down, noise reduction.
The number of plies of described sleeve is preferably the 2-6 layer, so not only practicality but also be convenient to make.For reducing vibration, the end socket of above-mentioned each outer layer sleeve upper end cantilever can be established support member, and this support member is separately fixed on the adjacent inner layer sleeve wall.
The most handy low-alloy steel of described muffler or stainless steel are made.
Exhaust hole on each layer sleeve lateral wall, its aperture is preferably the 2-5 millimeter.
In order to improve noise reduction, exhaust hole aperture on the outer layer sleeve should be littler than the exhaust hole aperture of internal layer adjacent sleeve, and the exhaust hole gross area is bigger than the adjacent inner layer sleeve exhaust hole gross area on the outer layer sleeve, the relieving capacity that is outer layer sleeve is bigger than adjacent inner layer sleeve relieving capacity, to keep steam discharge smooth and easy.
Be preferably 70-110 for the semidiameter of the steam boiler of 10 MPas, described adjacent sleeve circular cross section and expect that in the least the steam vent aperture on the porous plate of described plane is preferably the 8-12 millimeter.
Muffler of the present utility model, middle and high pressure steam has greatly reduced the discharge of steam noise through multi-step pressure reduction, is specially adapted to the steam boiler of the 3.9--16.9 MPa of present thermal power plant use, and its steam discharge noise can drop to about 60dB.Certainly, muffler of the present utility model also can be used for the noise reduction of other height, medium pressure gas discharge noise.In addition,, light a fire and the shortening of stove time, saved the fuel consumption of ignition process so make because this muffler relieving capacity is the 40-60% design by boiler capacity.
Accompanying drawing is a specific embodiment of the utility model.It is existing that details are as follows.
Fig. 1 is the main pseudosection of the utility model muffler.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
(1) is the flange that docks with the boiler gland steam exhauster among Fig. 1-3, (2) short tube under the porous plate of plane, (3) plane porous plate, (4) innermost layer sleeve, the upper cover of (5) innermost layer sleeve, (6) exhaust hole, (7) outer layer sleeve, (8) end socket of the end socket of outer layer sleeve lower end (9) outer layer sleeve upper end, the support member of (10) outer layer sleeve, above-mentioned muffler is made by the low-alloy steel or stainless steel.
