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.
