Each single streamlined silencer comprises streamlined flow guide covers at two ends and a middle pipe, each pipe comprises an outer end face perforated plate and silencing materials filled inside the pipe, the supports are arranged in a latticed manner, two ends of each single streamlined silencer are respectively and fixedly mounted at latticed crossing points of the supports, the axes of the single streamlined silencers are parallelly arrayed along the airflow direction, and the single streamlined silencers are fixedly mounted in a ventilating pipeline through the supports. The array streamlined silencer is convenient to mount, more energy-saving and more environment-friendly, on one hand, airflow resistance can be reduced, noise regenerated by airflow is decreased, so that silencing capacity is improved, and on the other hand, the power consumption of a ventilating system can be reduced.
Description
Technical field
The utility model relates to a kind of noise elimination noise reduction equipment, particularly the streamlined silencing apparatus of a kind of array-type.
Background technique
Noise is that a class causes people's agitation, the sound that is detrimental to health easily.Silencing apparatus is a kind of common device that air-flow is passed through and can effectively reduce noise, and the evaluation criterion of silencing apparatus performance mainly comprises sound deadening capacity, air-flow regenerated noise and three indexs of the pressure loss.People generally can arrange the influence of noise that silencing apparatus reduces ventilation equipment in ventilation system, but can increase flowing resistance like this, thereby can cause ventilation effect (and related air-conditioning effect, refrigeration, radiating effect etc.) to descend; Usually adopt the pressure head that promotes ventilation equipment, stablize ventilation effect, but can increase the power consumption when moving like this.Therefore, under the prerequisite that guarantees sound deadening capacity, the flowing resistance of silencing apparatus is more little, and then the rate of descent of ventilation effect is more low, and the power consumption of Zeng Jiaing is also just more few simultaneously.Therefore the streamlined silencing apparatus of a kind of array-type that provides of the utility model can reduce gas-flow resistance on the one hand, reduces the air-flow regenerated noise, thereby improves acoustical absorptivity, can reduce the power consumption of ventilation system on the other hand, more energy-conserving and environment-protective.
The model utility content
The streamlined silencing apparatus of a kind of array-type that the purpose of this utility model provides, easy for installation, it is convenient to safeguard, when reducing gas-flow resistance and reducing air-flow regenerated noise ability, has effectively improved acoustical absorptivity.
The purpose of this utility model can be achieved through the following technical solutions:
The streamlined silencing apparatus of a kind of array-type, it is characterized in that, comprise several streamlined silencing apparatus monomers and several supports, described streamlined silencing apparatus monomer is made up of the streamlined air guide sleeve at two ends and middle body, described body comprises the exterior edge face perforated plate and is filled in the muffler material of body inside, described several supports are latticed arrangement, described several streamlined silencing apparatus monomer two ends are fixedly mounted on respectively on the latticed intersection point of support, the axis of described each streamlined silencing apparatus monomer is arranged in parallel along airflow direction, is fixedly mounted in the ventilation duct by support.
Further, on the body exterior edge face perforated plate of described streamlined silencing apparatus monomer the hole be shaped as circle or polygonal.
Further, the body sectional shape of described streamlined silencing apparatus monomer is that the bight is the square of fillet.
Further, the inner muffler material of filling of the body of described streamlined silencing apparatus monomer is inorganic fire-retarded muffler material.
Further, the exterior material of described streamlined silencing apparatus monomer adopts anticorrosion coating material.

Fig. 2 is the structural representation of streamlined silencing apparatus monomer.
Fig. 3 is the structural representation of the streamlined air guide sleeve at streamlined silencing apparatus monomer two ends.
Fig. 4 is the structural representation of the body of streamlined silencing apparatus monomer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the streamlined silencing apparatus of a kind of array-type is characterized in that, comprises several streamlined silencing apparatus monomer 2 and several supports 3, and wherein, streamlined silencing apparatus monomer 2 is made up of the streamlined air guide sleeve at two ends and middle body, as shown in Figure 2.Described body comprises the exterior edge face perforated plate and is filled in the muffler material of body inside, described several supports are latticed arrangement, several streamlined silencing apparatus monomer two ends are fixedly mounted on respectively on the latticed intersection point of support simultaneously, the axis of described each streamlined silencing apparatus monomer is arranged in parallel along airflow direction, be fixedly mounted in the ventilation duct 1, as shown in Figure 1 by support.On the body exterior edge face perforated plate of described streamlined silencing apparatus monomer the hole be shaped as circle, as shown in Figure 4.The body sectional shape of described streamlined silencing apparatus monomer is that the bight is the square of fillet, can reduce gas-flow resistance, increases unit noise elimination area, and noise reduction is better.The streamlined air guide sleeve at the two ends of streamlined silencing apparatus monomer of while, as shown in Figure 3, this constructor interflow mechanics, better reduce gas-flow resistance, reduced the air-flow regenerated noise, reduced the pressure loss, thereby reduce the pressure of system fan, reduce the power consumption of ventilation system, more energy-conserving and environment-protective.
To sum up, the streamlined silencing apparatus of a kind of array-type that the utility model provides, easy for installation, can reduce gas-flow resistance on the one hand, reduce the air-flow regenerated noise, thereby improve acoustical absorptivity, can reduce the power consumption of ventilation system on the other hand, more energy-conserving and environment-protective.
Above-described only is mode of execution of the present utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
