Abstract
The utility model discloses a silencer with a function of extinguishing spark, which comprises a cylinder (1). The cylinder (1) consists of a primary anechoic chamber (2) with an inlet (5) and a secondary anechoic chamber (3) which is communicated with the primary anechoic chamber (2) and is provided with an outlet (6). The primary anechoic chamber (2) consists of a perforated plate (7) and various muffling materials. a baffle (4) is provided in the secondary anechoic chamber (3), opposite to the primary anechoic chamber (2). The utility model provides the silencer with the function of efficiently extinguishing the spark, adopts specific structure and materials, effectively combines the muffling function with the function of extinguishing the spark into one body, has more excellent function of extinguishing the spark than the conventional spark extinguisher and does not influence the running power of the diesel engine at all.
Description
Technical field
The utility model relates to a kind of silencing apparatus with high-effect fire-extinguishing star function, is installed in all kinds of diesel exhaust gas pipelines, to reach the function of falling noise abatement, especially can extinguish the carbon particle that burns in the air-flow, has avoided disaster hidden-trouble.
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 utility model 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 utility model 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 utlity model has following beneficial effect is: the utility model 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 utility model 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 the utility model volume 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 utility model principle is as follows: air-flow enters the utility model device from left end, at first enter the one-level anechoic room, 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 the utility model device 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).
