Abstract
The invention discloses an air exhaust noise silencer, comprising a boiler body and control valves. A silencer is arranged at the upper part of the boiler by the control valve; the silencer comprises a main air-emitting pipe, a main spherical air cavity, an auxiliary air-emitting pipe and an auxiliary spherical air cavity; one end of the main air-emitting pipe is flexibly connected with the boiler body and the other end thereof is fixedly connected with one end of the main air cavity; the main air-emitting pipe is equipped with a control valve; the other end of the main air cavity is connected with one end of the auxiliary air-emitting pipe and the other end of the air-emitting pipe is fixedly connected with the auxiliary spherical air cavity; and the auxiliary air-emitting pipe is provided with a control valve. One or two or a plurality of auxiliary spherical air cavities are arranged around the main spherical air cavity; one or two or a plurality of holes are arranged on the auxiliary spherical air cavity; therefore, the problem of high noise of various boilers caused by the high pressure of the exhausted air is solved; furthermore, the structure is simple, the mounting and dismounting are convenient and the maintenance is easy.
Description
Technical field
The present invention relates to a kind of Industrial Boiler with reducing the noise device, be specifically related to a kind of air exhaust muffler device.
Background technology
At present, the boiler of using in fields such as electric power, oil, chemical industry, metallurgy, weavings often adopts the mode of discharge of steam to reach the purpose of effective noise elimination.Because all kinds of boiler steam discharge steam are HTHP not only, and the discharging bandwidth, so only be difficult to satisfy the requirement of " industrial enterprise's noise criteria " with the erasure effect that mode reached of discharged steam.The environment of factory and workpeople's physical and mental health have been had a strong impact on.
Summary of the invention
The invention provides a kind of simple in structure, installation and removal convenient, also be convenient to the boiler air exhaust muffler device that keeps in repair.
Technical scheme of the present invention is:
A kind of Industrial Boiler exhaust muffling device comprises the boiler body and first control valve, and going up of described boiler body is provided with silencer by first control valve, and described silencer comprises main escape pipe, cue ball shape gas storehouse, from escape pipe and from spherical gas storehouse; One end of described main escape pipe and boiler body flexibly connect, the other end is fixedlyed connected with an end of main gas tank, first control valve is installed on the main escape pipe, and the other end in described gas storehouse is connected with a end from escape pipe, is fixedly connected with from spherical gas storehouse from the other end of escape pipe.From escape pipe second control valve is installed.Be provided with one, two or more around the described cue ball shape gas storehouse from spherical gas storehouse; Describedly be provided with one, two or more hole from spherical gas storehouse.
The present invention has the following advantages:
1, simple and reasonable.
2, intensity height, life-span are long.
3, advantage easy for installation.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Drawing reference numeral explanation: 1-boiler body, 2-master's escape pipe, 3-cue ball shape gas storehouse, 4-from spherical gas storehouse, 5-silencer, 6-be from escape pipe, 7-first control valve, 8-second control valve.
The specific embodiment
Referring to Fig. 1, the present invention includes boiler body (1), first control valve (7); Going up of described boiler body (1) is connected with silencer (5) by first control valve (7), and described silencer (5) comprises main escape pipe (2), cue ball shape gas storehouse (3), from escape pipe (6) and from spherical gas storehouse (4); One end of described main escape pipe (2) and boiler body (1) are for flexibly connecting, and the other end is fixedlyed connected with an end in cue ball shape gas storehouse (3), and first control valve (7) is installed on the described main escape pipe (2); The other end in described cue ball shape gas storehouse (3) is connected with a end from escape pipe (6), is fixedly connected with from spherical gas storehouse (4) from the other end of escape pipe (6); Describedly second control valve (8) is installed from escape pipe (6).Be provided with one, two or more around the described cue ball shape gas storehouse (3) from spherical gas storehouse (4).Describedly one, two or more hole have been provided with from spherical gas storehouse (4).
The present invention is based upon micropore jet theory and designed in conjunction with the noise-cancelling theory of decompression sound absorption, because it is fast that Boiler Steam is discharged general flow velocity, the pneumatic noise height, so just on boiler body, installed one mainly by, main escape pipe, cue ball shape gas storehouse, from escape pipe and the silencing apparatus formed from spherical gas storehouse, the main escape pipe of silencing apparatus with from escape pipe, all be separately installed with first control valve and second control valve, so that be used for controlling the pressure that boiler emission goes out gas, when gas pressure is waited valves and opened automatically in first road during greater than certain numerical value, gas is entered in the cue ball type air bag, and be added with at home and abroad at this valve and adorn resistive sound absorption cotton knot structure, it is that the spectral characteristic of the residual noise that sent according to the step-down body is designed, in order to absorb residual noise effectively.Gas by reduce pressure for the first time noise reduction after the escape pipe of associating advance enter in the same way a plurality of from spherical gas storehouse, discharge in hole on the spherical gas storehouse of associating, thereby reach the effect that reduces pressure, reduces noise, sound deadening capacity can reach the 30-42 decibel, makes it to reach " industrial enterprise's noise criteria " requirement.
Claims (2)
