Abstract
The invention discloses a silencer with function of extinguishing sparks, comprising a cylinder (1). The cylinder (1) consists of a primary silencing chamber (2) and a secondary silencing chamber (3), wherein the primary silencing chamber (2) is provided with an inlet (5), and secondary silencing chamber (3) is communicated with the primary silencing chamber is provided with an outlet; the primary silencing chamber (2) consists of a perforated plate (7) and various silencing materials; and a baffle plate (4) is arranged in a position in the secondary silencing chamber (3), which is opposite to the primary silencing chamber (2). The silencer with function of efficiently extinguishing sparks adopts the special structure and material, effectively integrates the silencing function with the spark extinguishing function into a whole body, has more remarkable spark extinguishing function than the conventional spark extinguisher and can not affect the operating power of the diesel enigne at all.
Description
Technical field
The present invention relates to a kind of silencing apparatus, be installed in all kinds of diesel exhaust gas pipelines,, especially can extinguish the carbon particle that burns in the air-flow, avoided disaster hidden-trouble to reach the function of falling noise abatement with high-effect fire-extinguishing star function.
Background technique
At present, the silencing apparatus that the manufacturer of domestic diesel engine silencing apparatus produces all has only single noise elimination function, though declare the star of can putting out a fire, can't make the particle of the burning that is being mingled with in the air-flow of discharging extinguish fully at all.Yet for oil carrier, liquefied gas carrier, natural gas boat, and the ship of other delivery combustible and explosive articles, in a single day the particle of burning touches goods, and ship is ruined the thing that the people dies and all can be taken place.So a lot of shipyards are installed baffler in exhaust duct after, also will install a spark arrester, certainly will cause the waste of shipbuilding cost and installing space like this, the exhaust resistance that has strengthened gas exhaust piping simultaneously makes diesel engine can't reach rated power.
Summary of the invention:
In order to address the above problem, the invention provides a kind of silencing apparatus with high-effect fire-extinguishing star function, adopt special construction and material, noise elimination function and function of extinguishing sparks are integrated as one effectively, the more conventional spark arrester of function of extinguishing sparks is remarkable more, and does not influence the operate power of diesel engine at all.
The present invention is by the following technical solutions: a kind of baffler with function of extinguishing sparks, it comprises cylindrical shell, cylindrical shell is by the one-level anechoic room that has import and be attached thereto the logical secondary anechoic room that has outlet and form, described one-level anechoic room is made up of perforated plate and various muffler material, is provided with baffle plate with one-level anechoic room opposite position in the described secondary anechoic room.
Described baffle plate is streamlined, and described cylindrical shell outside is provided with heat insulation rock wool cloth, and described perforated plate outside is provided with alkali glass silk flosssilk wadding cloth.
The present invention has following beneficial effect: the present invention makes noise elimination function remarkable more dissipative muffler and two kinds of noise-cancelling theorys of reactive muffler utilization that organically combines, and frequency of noise elimination is wideer, and performance is more stable.The present invention adopts put out a fire the again structure of star of sound absorption earlier, and in the time of sound absorption, Mars has obtained extinguishing of part, when air-flow arrives special Mars and extinguishes assembly, just can be extinguished fully and volume of the present invention little, convenient transportation is more saved material.

Embodiment
As depicted in figs. 1 and 2, a kind of baffler with function of extinguishing sparks, it comprises cylindrical shell, cylindrical shell is by the one-level anechoic room that has import and be attached thereto the logical secondary anechoic room that has outlet and form, described one-level anechoic room is made up of perforated plate and various muffler material, and described perforated plate outside is provided with alkali glass silk flosssilk wadding cloth.Be provided with streamlined baffle plate with one-level anechoic room opposite position in the described secondary anechoic room, the cylindrical shell outside is provided with heat insulation rock wool cloth.
The principle of the invention is as follows: air-flow enters apparatus of the present invention from left end, at first enters the one-level anechoic room, and this chamber is made of the sound-absorbing material of perforated plate and various density, and the sound wave that has comprised various frequency bands enters sound-absorbing material and eliminates the noise through behind the perforated plate.Because the sound-absorbing material density of each layer is all different, cuts down so sound waves of different frequencies has all played correspondingly.The sound wave sound intensity that comes out from the one-level silencing apparatus can reduce 20dB.The device right chamber is the secondary anechoic room, and the assembly of function of extinguishing sparks also is arranged in this chamber, can extinguish Mars again in the time of noise reduction.When air-flow entered the secondary anechoic room, cross section of fluid channel is long-pending to suddenly change, and acoustic reactance changes, and made sound wave generation reflection and interfered sound deadening capacity progress increasing.Air-flow is stopped in addition, and burning fire strikes on the obstacle with very fast speed and moment extinguishes, and passes through arc deflector again, makes the Mars that extinguishes along with air-flow is discharged apparatus of the present invention rotatably.In order to reduce flow resistance, obstacle has adopted fairshaped ellipsoidal head, and utilizes the curved surface of end socket and incoming flow sound wave to carry out diffuse reflection dexterously, causes repeatedly to absorb sound and interfere, to strengthen acoustically effective.
Claims (4)
1. baffler with function of extinguishing sparks, it is characterized in that it comprises cylindrical shell (1), cylindrical shell (1) is by the one-level anechoic room (2) that has import (5) and be attached thereto the logical secondary anechoic room that has outlet (6) and form (3), described one-level anechoic room (2) is made up of perforated plate (7) and various muffler material, is provided with baffle plate (4) with one-level anechoic room (2) opposite position in the described secondary anechoic room (3).
