The new high-efficiency anti-blowout type series muffler equipment is widely used in industrial factories and mines such as power generation, chemical industry, metallurgy, and textiles for the silencing of various types of boilers and turbine exhausts; fans; safety doors and other equipment Falling tone. This series of mufflers is developed based on the composite muffler principle of anti-spray and resistance. It has many advantages such as large sound attenuation, small size, light weight, easy installation and no maintenance.
1. TA type steam safety valve muffler suitable for various types of steam safety valves
Suitable for PCV/ERV safety valves (power release valves) of power station boilers and drum safety valves And safety doors for pressure devices such as superheater safety valves and reheater safety valves. The steam venting 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. To this end, the multi-stage throttling and small hole injection silencers that were common in the past were Sound reduction means should not be used. This limitation has always been a difficulty in the design of safety valve mufflers and is also the reason for the poor sound attenuation effect of safety door mufflers. The new TA type safety valve exhaust muffler for safety valves adopts the jet impedance composite muffler principle, in which large hole expansion replaces the smaller diameter flow control hole, which further strengthens the resistance and resistance elimination in the structure. The sound reduction mechanism achieves a sound elimination and noise reduction effect with a higher safety factor.
2. TB type ignition exhaust muffler suitable for boilers and other steam equipment
TB type boiler ignition exhaust muffler combines the most reasonable elimination features of PB type exhaust (gas) muffler. Designed based on acoustic principles. The high-pressure steam enters the pressure-reducing body after a flow control in the muffler. After the large-volume expansion and pressure-reducing, the exhaust noise often remains higher than the standard value due to many reasons such as the exhaust steam deviating from the design value. To this end, a combined multi-material composite structure sound-blocking and sound-absorbing cover is designed outside the decompression body. The composite sound-blocking sound-absorbing cover is designed based on the spectral characteristics of the residual noise emitted by the decompression body to effectively absorb the residual noise. . When the user installs it as required, the total sound attenuation volume can reach 36 to 42 decibels.
3. TD-type low-pressure steam muffler suitable for various low-temperature and low-pressure thermal devices
A large number of low-pressure boilers of 0.13Mpa and below are used in various industrial and mining enterprises. In the thermal system of power stations There are also a large number of low-pressure thermal devices, such as back-pressure steam turbines, deaerators, auxiliary air extractors, turbine oil pumps, boiler continuous blowdown, regular blowdown, etc. The above equipment is equipped with a muffler with a lightweight structure and easier installation according to the requirements of the exhaust pipe. For different noise elimination objects, special TDb type back pressure steam turbine exhaust muffler, TDy type deaerator muffler and other series of noise reduction products are designed to meet user requirements.
4. TC type pipe flushing muffler suitable for boiler commissioning purging and industrial pipeline installation and maintenance.
TC type pipe flushing muffler is used to reduce power station boiler commissioning purging. It is a type of special exhaust silencer and noise reduction equipment developed to eliminate the noise caused by the discharge of debris and exhaust gas emissions from the outlet of the flushing pipe. It can also be used to flush pipes to reduce noise and remove debris after installation or maintenance of other industrial pipelines and civil pipelines.
5. PB series small hole injection mufflers suitable for pipeline exhaust gases
PB series small hole injection mufflers are a new generation of noise reduction products developed in the 1990s. , based on the principle of small-hole pressure-reducing injection silencer, through optimized design, its noise reduction index, safety performance and service life are far superior to similar products on the market, and can better meet the needs of electric power, metallurgy, petroleum, chemical industry, textile , papermaking, food and other industries, exhaust steam (gas) venting of various boilers and pressure vessel pipelines with low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical and other parameters, and their safety valves and release valves exhaust steam (gas) noise reduction needs.
6. CF type fan silencer suitable for ventilation ducts
The fan is a general mechanical equipment with a wide range of uses, such as electric power, mining, machinery, metallurgy, and chemical industry The production of various industries is inseparable from fans. The noise generated by fans during operation often affects workers' health and disturbs the environment.
In particular, the aerodynamic noise radiated by the air inlets and outlets of fans adjacent to living areas is a major factor in environmental pollution and forms a public nuisance. It is one of the main targets of noise pollution control in my country's industrial sector.
7. CP-type diesel generator exhaust muffler suitable for diesel generator exhaust silencer
Diesel generators are widely used for their good economy and power performance. It is used in the production and operation of industrial and mining enterprises because the flue gas emitted during operation contains a certain amount of smoke (that is, the black smoke that everyone often sees). This phenomenon is caused by incomplete combustion of fuel. Therefore, conventional ventilation and exhaust mufflers, such as microperforated plate mufflers and mufflers with sound-absorbing fillers, are absolutely not advisable to be used in this environment because they can only temporarily reduce noise.
