Abstract
The utility model discloses a spark extinguishing and silencing device which comprises a barrel body (4). An air inlet end plate (3) and an air outlet end plate (7) are arranged at the two ends of the barrel body (4), an air inlet pipe (2) and an air outlet pipe (8) are respectively arranged on the air inlet end plate (3) and the air outlet end plate (7), an air inlet flange (1) is communicated with the barrel body (4) through the air inlet pipe (2), the air outlet flange (9) is communicated with the barrel body (4) through the air outlet pipe (8), a flow guide pipe (5) and a cavity partition plate (6) are arranged in the barrel body (4), the cavity partition plate (6) divides the air inlet end and the air outlet end of the barrel body (4) into to cavities, the flow guide pipe (5) penetrates through the cavity partition plate (6) to communicate the two cavities, and the air outlet tail end of the flow guide pipe (5) is in an arc shape inclining towards the inner wall of the barrel body (4). The spark extinguishing and silencing device can effectively reduce noise of a diesel engine in a tail gas exhausting process and meanwhile can fully extinguish non-burnout spark carried by tail gas.
Description
Technical field
The utility model relates to a kind of fire extinguishing star silencer.
Background technique
Diesel engine unit is the core drive that boats and ships are navigated by water, also be the core source of ship power supply, but diesel engine unit is in operation and produces quite high noise, wherein the noise in exhaust emissions process has occupied quite a few, to environment, brought pollution, and severe exacerbation crewman's work living environment.In addition, boats and ships are for improving endurance and reducing operating cost, the most not high heavy oil of fuel oil grade using of the fuel fired equipment such as diesel engine and boiler, thereby inevitably can be residual without clean-burning carbon particle in vent systems, be Mars, if Mars is along with air-flow enters atmosphere, once drop onto deck and touch oil gas or rock gas, to be that ship is ruined people and died, so a lot of shipyards are installed after baffler in exhaust duct, also installed a spark arrester, certainly will cause the waste of shipbuilding cost and installing space like this, strengthened the exhaust resistance of gas exhaust piping simultaneously, make diesel engine cannot reach rated power.
Summary of the invention
In order to address the above problem, the utility model provides a kind of fire extinguishing star silencer, can effectively reduce the noise of diesel engine vent gas in discharge process, the uncombusted Mars being mingled with fully can be extinguished in tail gas simultaneously.
The utility model has adopted following technological scheme: a kind of fire extinguishing star silencer, it comprises cylindrical shell, inlet flange, the flange of giving vent to anger, at the two ends of cylindrical shell, be provided with inlet end plate and the end plate of giving vent to anger, on described inlet end plate and the end plate of giving vent to anger, be respectively equipped with suction tude and steam outlet pipe, inlet flange is communicated with cylindrical shell by suction tude, and the flange of giving vent to anger is communicated with cylindrical shell by steam outlet pipe; In described cylindrical shell, be provided with honeycomb duct and separate space plate, described separate space plate is separated into two chambers by the air inlet and outlet end of cylindrical shell, and described honeycomb duct runs through separate space plate and two chambers are communicated with, the arc shape of end for tilting to cylinder inboard wall of giving vent to anger of described honeycomb duct
In described cylindrical shell, be provided with three honeycomb ducts, three honeycomb ducts are ringwise equably through separate space plate; In described cylindrical shell, be provided with four honeycomb ducts, four honeycomb ducts are ringwise equably through separate space plate; Give vent to anger center line of discharge and cylindrical shell 4 inwalls of end of described honeycomb duct are miter angle; The outside of described cylindrical shell is provided with heat insulation layer.
The utlity model has following beneficial effect: the utility model can effectively reduce the noise of diesel engine in exhaust emissions process, and stop high-temperature tail gas to airborne propagation heat, fully reached the function of cooling noise reduction; End bend loss center and the cylinder inboard wall of honeycomb duct are miter angle, air-flow collides cylinder inboard wall sound wave from honeycomb duct out time and reflects, cause sound energy attenuation, when air-flow and cylinder inboard wall collide simultaneously, the not most Mars that burns collides through reflection repeatedly, while reaching air outlet, is fully extinguished.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of fire extinguishing star silencer, it comprises cylindrical shell 4, inlet flange 1, the flange 9 of giving vent to anger, at the two ends of cylindrical shell 4, be provided with inlet end plate 3 and the end plate 7 of giving vent to anger, on described inlet end plate 3 and the end plate 7 of giving vent to anger, be respectively equipped with suction tude 2 and steam outlet pipe 8, inlet flange 1 is communicated with cylindrical shell 4 by suction tude 2, and the flange 9 of giving vent to anger is communicated with cylindrical shell 4 by steam outlet pipe 8, and the outside of cylindrical shell 4 is provided with heat insulation layer 10; In described cylindrical shell 4, be provided with honeycomb duct 5 and separate space plate 6, described separate space plate 6 is separated into two chambers by the air inlet and outlet end of cylindrical shell 4, described honeycomb duct 5 runs through separate space plate 6 and is fixed on separate space plate 6, two chambers are communicated with simultaneously, on separate space plate 6, can evenly be provided with two or three or four or five honeycomb ducts 5, in cylindrical shell 4, be provided with three honeycomb ducts 5, three honeycomb ducts 5 are ringwise equably through separate space plate 6, in cylindrical shell 4, be provided with 5, four honeycomb ducts 5 of four honeycomb ducts ringwise equably through separate space plate 6; It is straight line shape that honeycomb duct 5 is positioned at air inlet chamber section, and described honeycomb duct 5 is positioned at the arc shape of end for tilting to cylindrical shell 4 inwalls of giving vent to anger of the chamber section of giving vent to anger, and center line of discharge and the cylinder inboard wall of this arc shape end are miter angle.
The utility model principle is as follows: when the sound wave in exhaust process enters left chamber from suction tude, the unexpected expansion of channel cross-section, cause the acoustic impedance sudden change of pipeline, make to can't pass silencing apparatus and be reflected back sound source along the sound wave of some frequency of pipe transmmision, because sound wave can't pass silencing apparatus, also just pass not out, thereby reach the object of noise elimination, structure of the present utility model, air-flow comes in to discharge to steam outlet pipe from suction tude, and through the sudden change in four subchannel cross sections, sound energy attenuation is obvious altogether.Because end bend loss center and the cylinder inboard wall of honeycomb duct is miter angle, air-flow collides cylinder inboard wall sound wave from honeycomb duct out time and reflects, cause sound energy attenuation, when air-flow and cylinder inboard wall collide simultaneously, the not most Mars that burns collides through reflection repeatedly, while reaching air outlet, is fully extinguished.
