消声器是指对于同时具有噪声传播的气流管道,可以用附有吸声衬里的管道及弯头或利用截面积突然改变及其他声阻抗不连续的管道等降噪器件,使管道内噪声得到衰减或反射回去。前者称为阻性消声器,后者称为抗性消声器,也有阻抗复合式的消声

适用领域

大发棋牌下载新型高效抗喷阻型系列消声器设备被广泛使用于发电、化工、冶金、纺织等工业厂矿中用于各种型号锅炉、汽机排汽;风机;安全门等设备的消声降音。该系列消声器是根据抗、喷、阻复合消声原理所研制,具有消声量大、体积小、重量轻及安装方便无检修等诸多优点。

1、适用于各类蒸汽安全阀用的TA型蒸汽安全阀消声器

适用于电站锅炉安全阀(动力释放阀)、锅筒安全阀及过热器安全阀、再热器安全阀等压力装置的安全门。其蒸汽放空既应避免过大的噪声,更应让汽流顺利排出而不影响安全阀的排量、起跳和回座,为此,以往常见的多级节流及小孔喷注的消声降音手段即不宜采用,这种限制历来是安全阀消声器的设计难点,也是安全门消声器消声效果差的原因。新型用于安全阀的TA型安全阀排汽消声器采用了喷阻抗复合型消声原理,其中以大孔扩容代替了直径较小的控流孔,在结构上更加强化了抗性和阻性消声降音机理,达到了安全系数更高的消声降噪效果。

2、适用于锅炉等蒸汽设备的TB型点火排气消声器

TB型锅炉点火排汽消声器综合了PB型排汽(气)消声器最合理的消声原理所设计。高压蒸汽在消声器内经一次控流后进入降压体,经大容积再次扩容降压后,往往会因排汽偏离设计值等诸多原因,使排气噪声仍然高于标准值。为此,在降压体外设计了组合型多材料复合结构的阻声吸音罩,复合阻声吸音罩是根据降压体所喷出的剩余噪声的频谱特性所设计,用以有效地吸收剩余噪声。当用户按要求安装后,总消声量可达36~42分贝。

3、适用于各类低温低压热力装置的TD型低压蒸汽消声器

在各工矿企业使用着大量0.13Mpa及以下的低压锅炉,在电站热力系统中也有着大量的低压热力装置,如背压式汽轮机、除氧器、辅助抽气器、汽轮油泵、锅炉连续排污、定期排污等。上述设备按排汽管要求,配置结构轻便、安装更为方便的消声器。针对不同的消声对象,设计有专用的TDb型背压式汽轮机排汽消声器、TDy型除氧器消声器及其它系列消声降音产品,可满足用户的要求。

4、适用于锅炉试车吹扫及工业管道安装检修后的TC型冲管专用消声器

大发棋牌下载TC型管道冲管消声器,是为降低电站锅炉试车吹扫时冲管管道出口杂物排出及废气排放产生的噪声而研制开发的一类专用型排气消声降噪设备。也可用于其它工业管道和民用管道安装或检修后冲管消声降音及清除杂物。

5、适用于管道排放气体用的PB系列小孔喷注消声器

PB系列小孔喷注消声器系九十年代研制、开发的新一代降噪产品,它根据小孔降压喷注消声的原理,通过优化设计,其降噪指标、安全性能和使用寿命远优于市场上同类产品,可更好的满足电力、冶金、石油、化工、纺织、造纸、食品等工业的低压、中压、次高压、高压、超高压、亚临界等参数的各种锅炉、压力容器管道排汽(气)放空及其安全阀、释放阀排汽(气)的降噪需要。

6、适用于通风管道用的CF型风机消音器

风机是一种通用机械设备,其使用范围很广,电力、矿山、机械、冶金、化工等各行业的生产均离不开风机。风机在运转中产生的噪声常常成为影响工人健康和干扰环境的祸源。特别是邻近生活区的风机,其进风口和出风口所辐射的空气动力性噪声,更是污染环境的主要因素,形成公害,是我国工业部门治理噪声污染的主要对象之一。

7、适用于柴油发电机排气消声用的CP型柴油发电机排气消声器

柴油发电机以其良好的经济性和动力性能,被广泛用于工矿企业生产经营中,因其在运行过程排放的烟气中含有一定量的烟尘(也就是大家经常见到的黑烟),其现象是由于燃油燃烧不完全而产生的。因此常规型通风排气消声器,如微孔板式消声器和带有吸音填料的消音器要是使用在这种环境下,是绝不可取的,原因是其只能起到一时的消声降音。


The muffler refers to the air flow pipe that has noise propagation at the same time. Noise reduction devices such as pipes and bends with sound-absorbing lining or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance can be used to attenuate the noise in the pipeline. Or reflected back. The former is called a resistive muffler, the latter is called a resistance muffler, and there is also an impedance compound muffler
Area of application
The new high efficiency anti-spray type series muffler equipment is widely used in power generation, chemical industry, metallurgy, textiles and other industrial factories and mines for various types of boilers and steam engines; Fan; The muffled sound of equipment such as security doors. This series muffler is developed based on the principle of resistance, spray, and resistance compound muffler. It has many advantages such as large volume of muffler, small volume, light weight, and convenient installation without overhaul.
1, suitable for all types of steam relief valve TA steam relief valve muffler
Suitable for safety valve of boiler(power release valve), safety valve of boiler and safety valve of superheater and safety valve of reheater。 The steam emptying should not only avoid excessive noise, but also allow the steam flow to be discharged smoothly without affecting the displacement, take-off and return of the safety valve。 For this reason, the usual multi-stage throttle and small hole injection muffler is not suitable。 Used。 This kind of limitation is always the design difficulty of safety valve muffler, and it is also the reason why the safety door muffler has poor muffler muffler effect。 The new TA-type relief valve exhaust muffler used for the relief valve adopts the principle of spray resistance and compound muffler, in which the larger hole expansion replaces the smaller diameter flow control hole, and strengthens the resistance and resistance muffler。 The sound reduction mechanism achieves a higher noise reduction effect with a higher safety factor。
2, suitable for boiler and other steam equipment TB type ignition exhaust muffler
The TB boiler ignition exhaust muffler synthesizes the most reasonable muffler principle of the PB exhaust(gas) muffler. High-pressure steam enters the pressure-relief body after a single flow control in the muffler. After re-expansion of the large volume, it will often deviate from the design value due to many reasons, such as exhaust noise is still higher than the standard value. For this reason, a combined multi-material sound absorber is designed in vitro. The composite sound absorber is designed based on the spectral characteristics of the residual noise emitted by the pressure reducer to effectively absorb the remaining noise. When the user installs as required, the total muffler can reach 36 ~ 42 decibels.
3, applicable to various low-temperature low-pressure thermal devices TD type low-pressure steam muffler
A large number of low-pressure boilers with 0。13 Mpa and below are used in various industrial and mining enterprises。 There are also a large number of low-pressure thermal devices in the thermal system of the power station, such as back-pressure steam turbines, deoxygenators, auxiliary pumps, Steam wheel pumps, and boilers。 Continuous discharge, regular discharge, etc。。 The above equipment is equipped with a lighter structure and a more convenient muffler according to the requirements of the exhaust pipes。 For different muffler objects, a special TDb backpressure steam turbine exhaust muffler, TDy deoxygenator muffler and other series of muffler muffler products are designed to meet the user's requirements。
4, suitable for boiler test blowing and industrial pipeline installation and overhaul of TC type punching tube special muffler
The TC type pipeline muffler is a kind of special exhaust muffler developed to reduce the noise generated by the discharge of debris and exhaust gas discharge from the outlet of the pipeline during the test of the power station boiler. It can also be used for other industrial and civil pipeline installation or repair after punching tube silencing and cleaning debris.
PB series small hole injection muffler for pipe gas discharge
The PB series small hole injection muffler is a new generation of noise reduction products developed and developed in the 1990s。 According to the principle of small hole pressure reduction injection noise elimination, its noise reduction index, safety performance, and service life are far better than those of similar products in the market。 Boilers, pressure vessels, pipelines, etc。 that can better meet the parameters of low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, sub-critical, etc。 of the power, metallurgical, petroleum, chemical, textile, papermaking, food industries, etc。。 Exhaust(air) and its safety valve , release valve exhaust(gas) noise reduction needs。
CF-type fan muffler for ventilation ducts
The fan is a kind of universal mechanical equipment, which has a wide range of uses。 The production of electric power, mining, machinery, metallurgy, chemical industry and other industries can not be separated from the fan。 The noise generated by the fan during operation often becomes a source of trouble that affects workers 'health and interferes with the environment。 Especially the wind turbine near the living area, the aerodynamic noise emitted by the air inlet and outlet are the main factors that pollute the environment and form public hazards。 It is one of the main objects for the industrial departments to control noise pollution in China。
CP-type diesel generator exhaust muffler for diesel generator exhaust muffler
Diesel generators are widely used in the production and operation of industrial and mining enterprises because of their good economic performance。 Because they contain a certain amount of smoke(ie, black smoke that is often seen) in the smoke emitted during operation。 The phenomenon is due to incomplete fuel combustion。 Therefore, conventional ventilation mufflers, such as microporous panel mufflers and mufflers with sound-absorbing fillers, are not desirable in this environment because they can only serve as a momentary muffler。
