Abstract
The utility model discloses a spark annihilator, relating to the gas exhaust piping of mater/slave engine and boiler of cargo ship, passenger liner, container vessel, engineering ship and so on; an air outlet and an air inlet are separately arranged at the upper and lower ends of the barrel; a baffle is installed in the barrel above the air inlet; the periphery of the baffle is fixed on the inner wall of the barrel through a transverse bracing; a transverse partition plate is arranged in the barrel above the baffle; at least three through holes are arranged on the transverse partition plate; each through hole is connected with a bended inner sleeve. The utility model has features of spark annihilation, noise reduction, environment protection, convenient maintenance and so on, is a kind of security protection equipment for large marine main engine and boiler; the utility model can implement natural settling of spark in waste gas, achieve the objective of spark annihilation, guarantee no impurity, no fire potential and no noise pollution in the discharge waste gas of large marine main engine and boiler.
Description
Technical field
The utility model relates to gas exhaust pipings such as main and auxiliary machine such as the boats and ships that are applied to cargo ship, passenger steamer, container ship, working ship, boiler, makes to extinguish the extinguisher that spark and noise reduction are used.
Background technology
In recent years, China's shipbuilding industry fast development has become third place in the world big shipbuilding state.According to customs statistics, 2.9 ten thousand in China's outlet in January in this year boats and ships are worth 7.4 hundred million dollars, and compared with the same period of last year (together following) increases by 1.6 times and 23.9% respectively.But the problem that merits attention is that large ship main frame, boiler are produced when working in running spark, noise overflow and cause environmental pollution and lead to fire, causes directly and indirect economic loss, sometimes, also can cause casualties.
The utility model content
The utility model content
The utility model purpose is to design a kind of spark arrester that can in time put out a fire, reduce noise.
The utility model comprises a circular cylinder body, sets out gas port and air inlet respectively at the upper and lower end of cylindrical shell, in the cylindrical shell above air inlet baffle plate is set, and the periphery of described baffle plate is fixed on cylinder inboard wall by stull; Connect lateral partitions in the cylindrical shell above baffle plate, uniform at least three through holes on described lateral partitions connect the inner sleeve of a bending respectively on each through hole.
The utility model operation principle is: main frame or boiler combustion waste gas enter the spark arrester bottom from the air inlet of cylindrical shell, behind the baffle plate water conservancy diversion, enter the spark arrester middle part.Waste gas is through after the air inlet, water conservancy diversion, and its speed descends to some extent, and in the process that speed descends, Mars falls because of the unexpected variation of flow velocity, finishes the process that Mars extinguishes.Remaining waste gas enters spark arrester top by the spark arrester middle part through each inner sleeve, and air-flow is through behind the secondary speed-reducing, and remaining Mars is fallen on the dividing plate of spark arrester because of deadweight.Change and after the sedimentation, the Mars in the waste gas is eliminated substantially through secondary velocity, remaining waste gas is discharged by escape pipe.The process of secondary settlement also is the process of noise reduction, and waste gas is through behind the spark arrester, and being made an uproar by many Mars, height becomes no Mars, and the gas of low noise is discharged in the atmosphere.
The utlity model has extinguish spark, reduce noise, environmental protection, characteristics easy to maintenance; it is the safety features of large ship main frame, boiler; can realize the natural subsidence of Mars in the waste gas and reach the purpose of removing Mars, make large ship main frame, boiler emission waste gas reach environmental protection free from admixture, no disaster hidden-trouble, noiselessness pollution.
In order to realize secondary speed-reducing better, the both ends of the surface of the inner sleeve of bending described in the utility model are vertical mutually.
In addition, the utility model also is provided with water inlet in the upper end of cylindrical shell, sets out the mouth of a river in the lower end of cylindrical shell, and the cylinder lateral wall below baffle plate is provided with ash output opening.Can adopt running water flushing cylindrical shell easily, be deposited in the impurity in the spark arrester, can discharge by ash output opening.The sewage of band ash is discharged from delivery port.
The utility model is also offered water hole on lateral partitions.
Air inlet described in the utility model is arranged on the axis of cylindrical shell, and described baffle plate is the taper shape that periphery is higher than the center.The flow direction that helps direct exhaust makes waste gas change to the state of dispersion from the state of concentrating.
Make for convenience, install, disperse air inlet, the wrap direction of each inner sleeve is one forward.
Described cylindrical shell is provided with thermal insulation layer outward.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 be among Fig. 1 A-A to view.
The specific embodiment
As shown in Figure 1, 2, set out gas port 2 and air inlet 13 respectively at the upper and lower end axis place of circular cylinder body 4,2 one sides also are provided with water inlet 3 in the gas outlet, also set out the mouth of a river 12 in air inlet 13 1 sides.At circular cylinder body 4 outer walls thermal insulation layer 5 is set.
In the cylindrical shell 4 above air inlet 13 baffle plate 10 is set, baffle plate 10 is the taper shape that periphery is higher than the center, and the periphery of baffle plate 10 is fixed on cylindrical shell 4 inwalls by stull 9.
Connect lateral partitions 8 in the cylindrical shell 4 above baffle plate 10, uniform at least five through holes on lateral partitions 8 connect the inner sleeve 7 of a bending respectively on each through hole, and the both ends of the surface of inner sleeve 7 are vertical mutually, and the wrap direction of each inner sleeve 7 is one forward.On lateral partitions 8, also offer water hole 14,15.
Among Fig. 1,1 is hanger, and 6 is installation foot.
