消聲器是指對(duì)于同時(shí)具有噪聲傳播的氣流管道,可以用附有吸聲襯里的管道及彎頭或利用截面積突然改變及其他聲阻抗不連續(xù)的管道等降噪器件,使管道內(nèi)噪聲得到衰減或反射回去。前者稱為阻性消聲器，后者稱為抗性消聲器，也有阻抗復(fù)合式的消聲

適用優(yōu)先域

新型高效抗噴阻型系列消聲器設(shè)備被廣泛使用于發(fā)電、化工、冶金、紡織等工業(yè)廠礦中用于各種型號(hào)鍋爐、汽機(jī)排汽;風(fēng)機(jī);安全門等設(shè)備的消聲降音。該系列消聲器是根據(jù)抗、噴、阻復(fù)合消聲原理所研制，具有消聲量大、體積小、重量輕及安裝方便無(wú)檢修等諸多優(yōu)點(diǎn)。

1、適用于各類蒸汽安全閥用的TA型蒸汽安全閥消聲器

適用于電站鍋爐安全閥(動(dòng)力釋放閥)、鍋筒安全閥及過(guò)熱器安全閥、再熱器安全閥等壓力裝置的安全門。其蒸汽放空既應(yīng)避免過(guò)大的噪聲，更應(yīng)讓汽流順利排出而不影響安全閥的排量、起跳和回座，為此，以往常見(jiàn)的多級(jí)節(jié)流及小孔噴注的消聲降音手段即不宜采用，這種限制歷來(lái)是安全閥消聲器的設(shè)計(jì)難點(diǎn)，也是安全門消聲器消聲效果差的原因。新型用于安全閥的TA型安全閥排汽消聲器采用了噴阻抗復(fù)合型消聲原理，其中以大孔擴(kuò)容代替了直徑較小的控流孔，在結(jié)構(gòu)上更加強(qiáng)化了抗性和阻性消聲降音機(jī)理，達(dá)到了安全系數(shù)更高的消聲降噪效果。

2、適用于鍋爐等蒸汽設(shè)備的TB型點(diǎn)火排氣消聲器

TB型鍋爐點(diǎn)火排汽消聲器綜合了PB型排汽(氣)消聲器比較合理的消聲原理所設(shè)計(jì)。高壓蒸汽在消聲器內(nèi)經(jīng)一次控流后進(jìn)入降壓體，經(jīng)大容積再次擴(kuò)容降壓后，往往會(huì)因排汽偏離設(shè)計(jì)值等諸多原因，使排氣噪聲仍然高于標(biāo)準(zhǔn)值。為此，在降壓體外設(shè)計(jì)了組合型多材料復(fù)合結(jié)構(gòu)的阻聲吸音罩，復(fù)合阻聲吸音罩是根據(jù)降壓體所噴出的剩余噪聲的頻譜特性所設(shè)計(jì)，用以有效地吸收剩余噪聲。當(dāng)用戶按要求安裝后，總消聲量可達(dá)36~42分貝。

4、適用于鍋爐試車吹掃及工業(yè)管道安裝檢修后的TC型沖管專用消聲器

TC型管道沖管消聲器，是為降低電站鍋爐試車吹掃時(shí)沖管管道出口雜物排出及廢氣排放產(chǎn)生的噪聲而研制開(kāi)發(fā)的一類專用型排氣消聲降噪設(shè)備。也可用于其它工業(yè)管道和民用管道安裝或檢修后沖管消聲降音及清除雜物。

5、適用于管道排放氣體用的PB系列小孔噴注消聲器

PB系列小孔噴注消聲器系九十年代研制、開(kāi)發(fā)的新一代降噪產(chǎn)品，它根據(jù)小孔降壓噴注消聲的原理，通過(guò)優(yōu)化設(shè)計(jì)，其降噪指標(biāo)、安全性能和使用壽命遠(yuǎn)優(yōu)于市場(chǎng)上同類產(chǎn)品，可更好的滿足電力、冶金、石油、化工、紡織、造紙、食品等工業(yè)的低壓、中壓、次高壓、高壓、超高壓、亞臨界等參數(shù)的各種鍋爐、壓力容器管道排汽(氣)放空及其安全閥、釋放閥排汽(氣)的降噪需要。

6、適用于通風(fēng)管道用的CF型風(fēng)機(jī)消音器

風(fēng)機(jī)是一種通用機(jī)械設(shè)備，其使用范圍很廣，電力、礦山、機(jī)械、冶金、化工等各行業(yè)的生產(chǎn)均離不開(kāi)風(fēng)機(jī)。風(fēng)機(jī)在運(yùn)轉(zhuǎn)中產(chǎn)生的噪聲常常成為影響工人健康和干擾環(huán)境的禍源。特別是鄰近生活區(qū)的風(fēng)機(jī)，其進(jìn)風(fēng)口和出風(fēng)口所輻射的空氣動(dòng)力性噪聲，更是污染環(huán)境的主要因素，形成公害，是我國(guó)工業(yè)部門治理噪聲污染的主要對(duì)象之一。

7、適用于柴油發(fā)電機(jī)排氣消聲用的CP型柴油發(fā)電機(jī)排氣消聲器

柴油發(fā)電機(jī)以其良好的經(jīng)濟(jì)性和動(dòng)力性能，被廣泛用于工礦企業(yè)生產(chǎn)經(jīng)營(yíng)中，因其在運(yùn)行過(guò)程排放的煙氣中含有一定量的煙塵(也就是大家經(jīng)常見(jiàn)到的黑煙)，其現(xiàn)象是由于燃油燃燒不完全而產(chǎn)生的。因此常規(guī)型通風(fēng)排氣消聲器，如微孔板式消聲器和帶有吸音填料的消音器要是使用在這種環(huán)境下，是不可取的,原因是其只能起到一時(shí)的消聲降音。

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.
