Abstract
The utility model relates to a noise reduction device for an exhaust pipe. The noise reduction device comprises an exhaust pipe, wherein a plurality of hush pipes communicated with the exhaust pipe for exhausting are arranged on the exhaust pipe. Each hush pipe comprises a tube body made of a porous material and a connecting piece connected with the open end of the tube body. The tube body is a titanium bar filter element. Air flow enters the hush pipes through the exhaust pipe, so as to increase the contact area when the air flows and reduce the air flowing speed, and the micro pores can effectively disperse air flow and absorb sound, so as to realize noise reduction. The tube body is the titanium bar filter element, and the titanium bar filter element is a waste titanium bar filter element used in other workshop sections, so as to facilitate material collection, recycle waste and save cost. For the exhausting after using the structure, the noise reduction effect is distinct, and no impact is generated to the physical health of operators and the production and living of citizens who live in the region near enterprises. The noise reduction device is suitable for application and popularization in industrial production, especially in the exhausting workshop section.
Description
Technical field
The utility model belongs to the environmental protection equipment field, is specifically related to a kind of outlet pipe denoising device.
Background technique
In commercial production; Exhaust emptying noise is generally produced by the unstability that high velocity air flows; Airflow flowing has high temperature, high pressure, characteristics at a high speed, and it is the main source of industry noises such as chemical industry, oil, electric power, pharmacy, and the noise intensity of its discharging is high; Frequency spectrum is wide and to involve scope wide, has had a strong impact on the healthy of operator and the neighboring area resident's of enterprise productive life.
At present; Generally be employed in the diameter that wraps up soundproof material on the outlet pipe or increase discharge pipe for reducing the noise that produces in the commercial production, but soundproof material damage apt to deteriorate under the air-flow effect of high temperature can't be satisfied decrease of noise functions; Maintenance or the cost of changing are high; Increasing the outlet pipe diameter has then increased the floor space of equipment, increased fund input, and noise reduction is not obvious.
The model utility content
The utility model technical problem to be solved is: a kind of outlet pipe denoising device that can reduce noise is provided.
The technological scheme that realizes the purpose employing of the utility model is: a kind of outlet pipe denoising device, comprise outlet pipe, and said outlet pipe is provided with a plurality of hush pipes that are communicated with and are used for exhaust with it.
Further be that said hush pipe comprises cylindrical shell of being processed by poromerics and the link that is connected the cartridge openings end.
Further be that said cylindrical shell is a titanium rod filter core.
Further be that said a plurality of hush pipes are distributed on the outlet pipe.
The beneficial effect of the utility model is: said outlet pipe is provided with a plurality of hush pipes that are communicated with and are used for exhaust with it; Air communication is crossed outlet pipe and is got into hush pipe, the area of contact when having increased air current flow, the flowing velocity of having slowed down air-flow; Reduced noise; Said hush pipe comprises the cylindrical shell that poromerics is processed, and the micropore of this cylindrical shell can effectively disperse air-flow and can absorb sound, realizes noise reduction.Said cylindrical shell is a titanium rod filter core, and this titanium rod filter core is other workshop sections used discarded titanium rod filter cores, draws materials conveniently, makes recycling waste, practices thrift cost.Use this structure final vacuum, noise reduction is obvious, can the healthy of operator and the neighboring area resident's of enterprise productive life not impacted.
Description of drawings
Fig. 1 is the utility model structural representation.
Mark among the figure: hush pipe 1, cylindrical shell 1.1, link 1.2, outlet pipe 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The utility model relates to a kind of outlet pipe denoising device.This kind outlet pipe denoising device comprises outlet pipe 2, and said outlet pipe 2 is provided with a plurality of hush pipes 1 that are communicated with it and are used for exhaust.
The air-flow that gets in the outlet pipe 2 all is discharged in the hush pipe 1 that is connected with outlet pipe 2, is discharged by hush pipe 1 at last, has increased the area of contact of air-flow in exclusion process, and the flowing velocity of having slowed down air-flow has reduced noise.
Said hush pipe 1 can be chip baffler or bent-tube boiler hush pipe, but produces the chip baffler or the bent-tube boiler hush pipe needs special device, and difficulty of processing is high; If directly buy; Then increase cost, the hush pipe 1 that the utility model is selected for use comprises the cylindrical shell of being processed by poromerics 1.1, for ease cylindrical shell 1.1 is connected with outlet pipe 2; Be provided with link 1.2 at cylindrical shell 1.1 opening ends, this link 1.2 adopts bolt to be connected with cylindrical shell 1.1.Material with micropore performance is metal or plastics, and as preferably, it is titanium rod filter core that the utility model adopts the poromerics of processing cylindrical shell 1.1, and this titanium rod filter core is that other workshop sections of enterprise use the material of afterwards discarding, and need not to increase cost.This titanium rod filter core is with after outlet pipe 2 is communicated with, and air-flow gets into titanium rod filter core, because former other workshop section's mediums that is used for of the excellent filter core of titanium that should discard; Therefore in titanium rod cartridge surface micropore is arranged; The diameter of this micropore confirms that according to the discarded titanium rod filter core that is adopted the micro-pore diameter that the utility model is selected for use is 5～10 μ m, and the micropore that air communication is crossed on the titanium rod filter core is got rid of; Micropore can effectively disperse air-flow and can absorb sound, can not produce noise.The titanium rod filter core quantity that connects on the said outlet pipe 2 is according to the air-flow size, and intensity is confirmed.Said outlet pipe 2 can adopt bolt to be connected with the Placement of titanium rod filter core or weld; But because the thinner thickness of outlet pipe 2 tube walls; Be difficult for tightening; Sealability when guaranteeing that outlet pipe 2 and titanium rod filter core is communicated with, the Placement that the utility model adopted be for welding, on its soldering point position link 1.2 and the face that outlet pipe 2 contacts.
In order to make the pressure in the outlet pipe 2 even, improve the working life of outlet pipe 2, and make whole device attractive in appearance, said a plurality of hush pipes 1 are distributed on the outlet pipe 2.
