The silencing apparatus of the above Four types can only play the effect of single reduction exhaust sound, does not have fully can not temperature and the pollutant of Exhaust Gas to be reduced and process, function singleness from the angle of protection of the environment.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of silencing apparatus that reduces delivery temperature is provided.Change the traditional concept that silencing apparatus can only reduce exhaust sound, make existing silencing apparatus when realizing that exhaust sound reduces, reduce delivery temperature, and certain exhaust emission control function is arranged.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of silencing apparatus that reduces delivery temperature, include suppressor case, be provided with outlet pipe in it, its main feature is also to include outlet pipe and is comprised of downtake pipe and second exhaust pipe, is provided with water spray projector system between downtake pipe and second exhaust pipe.
The described silencing apparatus that reduces delivery temperature, described water spray projector system is provided with the core cylinder with the outlet pipe coaxial line in the middle, is provided with ring pipe in the outside of core cylinder, is evenly distributed with shower on ring pipe; Ring pipe is communicated with water intake on being located at suppressor case.
The described silencing apparatus that reduces delivery temperature also includes between second exhaust pipe and relief opening and is provided with mixing chamber, be provided with to mix cold hole on the suppressor case corresponding with mixing chamber, mixing chamber with mix cold hole and be connected.
The described silencing apparatus that reduces delivery temperature also includes and be provided with waste pipe on suppressor case; Be provided with upper clapboard in suppressor case, lower clapboard; Be provided with weep hole on lower clapboard.
The described silencing apparatus that reduces delivery temperature also includes in described core cylinder and described mixing chamber and is provided with the sound absorption bar.
The beneficial effects of the utility model are: realize reducing delivery temperature when exhaust sound reduces, reduce pellet and part harmful gas in tail gas, the thermo-pollution and the environmental pollution that cause to reduce exhaust.

Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Embodiment 1: see Fig. 1, Fig. 2, Fig. 3, a kind of silencing apparatus that reduces delivery temperature, include suppressor case 3, be provided with outlet pipe 8 in it, also include outlet pipe 8 and formed by downtake pipe 8-1 and second exhaust pipe 8-2, be provided with water spray projector system 5 between downtake pipe 8-1 and second exhaust pipe 8-2.Tail gas fully contacts with water droplet, and most heat is passed to water droplet.
Described water spray projector system 5 is provided with the core cylinder 4 with outlet pipe 8 coaxial lines in the middle, is provided with ring pipe 5-2 in the outside of core cylinder 4, is evenly distributed with shower 5-1 on ring pipe 5-2; Ring pipe 5-2 is communicated with water intake 5-3 on being located at suppressor case 3.
Also include between second exhaust pipe 8-2 and relief opening 6 and be provided with mixing chamber 12, be provided with on the suppressor case corresponding with mixing chamber 12 3 and mix cold hole 2, mixing chamber 12 with mix cold hole 2 and be connected.The type of cooling of cool air is mixed in employing, and the cool air that mixes directly mixes the reduction temperature with tail gas.
Also include and be provided with waste pipe 9 on suppressor case 3; Be provided with upper clapboard 11 in suppressor case 3, lower clapboard 7; Be provided with weep hole 7-1 on lower clapboard 7.
The described silencing apparatus that reduces delivery temperature also includes and be provided with sound absorption bar 1-1,1-2 in described core cylinder 4 and described mixing chamber 12.
This scheme adopts the two-stage type of cooling.The first order adopts heat exchange (tail gas-water droplet) type of cooling; The type of cooling of mixing cool air is adopted in the second level, and the cool air that mixes directly mixes the reduction temperature with tail gas.It is cooling that at first the gas of discharging from outlet pipe enter the first order.By fully the contacting of tail gas and water droplet, most heat is passed to water droplet in the first order.Through the first order cooled gas, enter the second level by the connecting tube of two-stage cooling.In the second level, the negative pressure that forms when utilizing the tail gas flow at high speed sucks extraneous cool air, and cold and hot gas is discharged from outlet pipe after mixing.
Key point of the present utility model: utilize the water crushing technology that the water column of ejection is broken into small water droplet, increase the area of contact with tail gas.The negative pressure of utilizing exhaust airstream to produce under the condition that does not need external force, sucks cool air from the external world.
Concrete implementing measure of the present utility model: this muffler body structure adopts two-stage expansion chamber silencing apparatus, arranges the water-cooled water spray projector system in first order expansion chamber, in second level expansion chamber arrangement air-cooling structure.During this silencing apparatus work, the current through the booster water pump pressurization enter shower by water intake.Open the aperture that well-regulated diameter is 1.5mm on shower, high-pressure water flow flows out through the 1.5mm aperture, forms the high speed water column.High speed water column and suppressor case 3 inwalls and core cylinder 4 clash into, and are broken into the small water droplet of diameter.Water droplet after fragmentation contacts with the tail gas mixing that outlet pipe 8 enters, and the heat in tail gas is passed to little water droplet, and the water droplet that absorbs at last heat is back to water tank through waste pipe 9 and recycles.Enter next stage through the tail gas after water-cooled cooling.Form negative pressuren zone around exhaust gas flow, utilize this negative pressure that extraneous cool air is sucked by mixing cold hole 2.Cool ambient air approach gas-entered passageway mixes in high-temperature tail gas.For high temperature gas flow, such mix cold can be in air-flow path formation temperature gradient, intermediate heat, surrounding is cold.And this temperature gradient can cause sound velocity gradient, and namely sound wave is crooked to the passage perisporium.Owing to being furnished with sound absorption bar 1 at the passage perisporium, play the effect of resistance noise reduction.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
