Abstract
The invention discloses a spark extinguishing type silencer. The spark extinguishing type silencer comprises a barrel (4), wherein an air inlet end plate (3) and an air outlet end plate (7) are arranged at the two ends of the barrel (4), an air inlet pipe (2) and an air outlet pipe (8) are arranged on the air inlet end plate (3) and on the air outlet end plate (7) respectively, an air inlet flange (1) is communicated with the barrel (4) through the air inlet pipe (2), an air outlet flange (9) is communicated with the barrel (4) through the air outlet pipe (8), flow guide pipes (5) and a partition cavity board (6) are arranged in the barrel (4), the interior of the barrel (4) is divided into two cavities which are located at the air inlet end and at the air outlet end respectively by the partition cavity board (6), the flow guide pipes (5) penetrate through the partition cavity board (6) to enable the two cavities to be communicated, and the air outlet tail end of each flow guide pipe (5) is in a shape of an arc and inclines towards the inner wall of the barrel (4). The spark extinguishing type silencer has the advantages that noise generated when tail gas of a diesel engine is discharged can be effectively lowered, and sparks which are not completely burnt in the tail gas can be fully extinguished.
Description
Technical field
The present invention relates to a kind of fire extinguishing star baffler.
Background technique
Diesel engine unit is the core drive that boats and ships are navigated by water, it is also the core source of ship power supply, but diesel engine unit is in operation and produces quite high noise, wherein the noise in the exhaust emissions process has occupied quite a few, brought pollution to environment, 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 used 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 the people and died, after so a lot of shipyards are installed 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 can't reach rated power.
Summary of the invention
In order to address the above problem, the invention provides a kind of fire extinguishing star baffler, can effectively reduce the noise of diesel engine vent gas in discharge process, the uncombusted Mars be mingled with in tail gas fully can be extinguished simultaneously.
The present invention has adopted following technological scheme: a kind of fire extinguishing star baffler, it comprises cylindrical shell, inlet flange, the flange of giving vent to anger, be provided with inlet end plate at the two ends of cylindrical shell and the end plate of giving vent to anger, be respectively equipped with suction tude and steam outlet pipe on described inlet end plate and the end plate of giving vent to anger, 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; Be provided with honeycomb duct and separate space plate in described cylindrical shell, 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 the 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
Be provided with three honeycomb ducts in described cylindrical shell, three honeycomb ducts are ringwise equably through the separate space plate; Be provided with four honeycomb ducts in described cylindrical shell, four honeycomb ducts are ringwise equably through the 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 present invention has following beneficial effect: the present invention can effectively reduce the noise of diesel engine in the exhaust emissions process, and stops high-temperature tail gas to airborne propagation heat, has 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 from honeycomb duct out time collision cylinder inboard wall sound wave reflect, 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of fire extinguishing star baffler, it comprises cylindrical shell 4, inlet flange 1, the flange 9 of giving vent to anger, be provided with inlet end plate 3 and the end plate 7 of giving vent to anger at the two ends of cylindrical shell 4, be respectively equipped with suction tude 2 and steam outlet pipe 8 on described inlet end plate 3 and the end plate 7 of giving vent to anger, 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; Be provided with honeycomb duct 5 and separate space plate 6 in described cylindrical shell 4, 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, can evenly be provided with two or three or four or five honeycomb ducts 5 on separate space plate 6, be provided with three honeycomb ducts 5 in cylindrical shell 4, three honeycomb ducts 5 are ringwise equably through separate space plate 6, be provided with 5, four honeycomb ducts 5 of four honeycomb ducts ringwise equably through separate space plate 6 in cylindrical shell 4; 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 principle of the invention 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, also just pass not out because sound wave can't pass silencing apparatus, thereby reach the purpose of noise elimination, structure of the present invention, 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 from honeycomb duct out time collision cylinder inboard wall sound wave reflect, 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.
