Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.

If Fig. 1 is to the of the present utility model this boiler exhaust gas silencing means shown in 5, it includes boiler body 1, airway 2 and silencing means 3. Tail gas is imported in described silencing means 3 by described airway 2 by described boiler body 1, the tail gas not only flow velocity produced in boiler body 1 is fast, and along with noise, environment can be caused huge infringement, therefore tail gas is imported and silencing means 3 carries out blood pressure lowering, noise reduction. Described silencing means 3 includes noise reduction framework 10, ingress pipe 20 and delivery line 30, ingress pipe 20 tail gas is led into, tail gas is carried out blood pressure lowering, noise reduction by noise reduction framework 10, delivery line 30 by after treatment tail gas derive. It is provided with anechoic chamber 15 in described noise reduction framework 10, tail gas is imported in described anechoic chamber 15 by a right angle mozzle 21 by described ingress pipe 20, anechoic chamber 15 is a cavity volume with larger space, tail gas is entered in anechoic chamber 15 suddenly by ingress pipe 20, due to the sharply increase in space, the stream pressure of tail gas can dramatic drop-off. Right angle mozzle 21 is a right angle conduit, therefore can slow down the impact of air-flow, has energy dissipating effect, it is possible to reduce the flow velocity of tail gas. Described noise reduction framework 10 includes the inwall 101 and the outer wall 102 that form silencing cavity 100 each other, a silencing cavity 100 is defined between inwall 101 and outer wall 102, the flowed energy of tail gas forms eddy current in silencing cavity 100, it is possible to consumed energy, effectively reduces pneumatic noise. Described inwall 101 is provided with some convex bubbles 103 towards the end face of described outer wall 102, and convex bubble 103 can slow down the impact of air-flow, increases the contact area of air-flow and silencing cavity 100, effective consumed energy, reduces noise further.Being provided with the first silencing cotton 104 in described silencing cavity 100, this first silencing cotton 104 can absorb the vibrational energy of pneumatic noise, and the noise of tail gas may finally be completely eliminated. Being provided with the second silencing cotton 31 and filtering layer 32 in described delivery line 30, the effect of the second silencing cotton 31 is consistent with the effect of the first silencing cotton 104 so that the tail gas that delivery line 30 is discharged does not have noise. Filtering layer 32 can eliminate, absorb in tail gas flue dust and harmful gas, be effectively ensured discharge gas safety up to standard. Being preferably, described second silencing cotton 31 is located at inside described filtering layer 32, and tail gas first carries out noise reduction, then carries out dedusting.

Wherein, described airway 2 is to be connected to form by multiple U-tube so that the roundabout transmission of tail gas, it is possible to slow down the gas shock of tail gas to greatest extent. Described airway 2 connects described ingress pipe 20, and tail gas enters through ingress pipe 20 and carries out noise reduction, blood pressure lowering in noise reduction framework 10.

Described right angle mozzle 21 is double; two right angles mozzle, tail gas in right angle mozzle 21 through twice break-in, it is possible to repeatedly consume energy, slow down the impact velocity of air-flow further.

Described filtering layer 32 includes the filtering meshes 320, active carbon layer 321 and the filter paper layer 322 that set gradually, and described filtering meshes 320 is near described second silencing cotton 31. Filtering meshes 320 can stop that big dust particle, active carbon layer 321 can absorb the harmful substance in tail gas, eliminates stink, and filter paper layer 322 can filter out the dust in tail gas further. Through multiple times of filtration and absorption, flue dust in tail gas, other impurity and harmful substance are effectively eliminated.

Connecting a cloth fan housing 22 on described right angle mozzle 21 port, described cloth fan housing 22 is rounded, and this cloth fan housing 22 covers on the air outlet of right angle mozzle 21. Described cloth fan housing 22 is provided with convex closure 220, and described convex closure 220 side is provided with wind distributing hole 221, and described convex closure 220 is evenly distributed on some circumference coaxial with described cloth fan housing 22, being oriented clockwise of described wind distributing hole 221. Wind distributing hole 221 is that annular is arranged clockwise, it is possible to makes tail gas form annular airflow, in dispersed entrance anechoic chamber 15, not only slows down gas shock, and can strengthen the blood pressure lowering of tail gas, noise reduction. So far, the present utility model purpose is accomplished.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
