The new high-efficiency anti-spray resistance muffler equipment is widely used in power generation, chemical industry, metallurgy, textile and other industrial plants and mines for various types of boilers, steam turbine exhaust; fans; safety doors and other equipment for noise reduction and sound reduction. This series of muffler is developed according to the principle of anti-spraying, spraying and resistance combined muffler. It has many advantages such as large noise reduction, small size, light weight, easy installation and no maintenance.
1. TA type steam safety valve muffler suitable for all kinds of steam safety valves
It is suitable for the safety door of power plant boiler safety valve (power release valve), boiler safety valve, superheater safety valve, reheater safety valve and other pressure devices. The steam venting should not only avoid excessive noise, but also allow the steam flow to be smoothly discharged without affecting the displacement, take-off and reseating of the safety valve. For this reason, the conventional multi-stage throttling and small hole injection muffler The sound-reducing method is not suitable for use. This restriction has always been the design difficulty of the safety valve muffler, and it is also the reason for the poor noise reduction effect of the safety door muffler. The new type TA safety valve exhaust muffler used for safety valve adopts the principle of spray impedance compound muffler. Among them, the large hole expansion is used to replace the small diameter control hole, and the structure is more strengthened in resistance and resistance. The sound reduction mechanism achieves a noise reduction and noise reduction effect with a higher safety factor.
2. TB type ignition exhaust muffler suitable for boilers and other steam equipment
The TB boiler ignition exhaust muffler is designed based on the most reasonable muffler principle of the PB exhaust (gas) muffler. The high-pressure steam enters the depressurizing body after being controlled once in the muffler. After the large volume is expanded again to reduce the pressure, the exhaust noise is often higher than the standard value due to many reasons such as the deviation of the exhaust steam from the design value. To this end, a combined multi-material composite structure sound-absorbing sound-absorbing cover was designed outside the voltage-reducing body. The composite sound-absorbing sound-absorbing cover was designed according to the spectral characteristics of the residual noise ejected by the pressure-reducing body to effectively absorb the residual noise . When the user installs as required, the total noise reduction can reach 36 to 42 decibels.
3. TD type low pressure steam muffler suitable for all kinds of low temperature and low pressure thermal equipment
A large number of low-pressure boilers of 0.13Mpa and below are used in various industrial and mining enterprises, and there are also a large number of low-pressure thermal devices in the thermal system of power stations, such as back-pressure steam turbines, deaerators, auxiliary extractors, steam turbine oil pumps, and continuous blowdown of boilers. , Regular sewage disposal, etc. According to the requirements of the exhaust pipe, the above equipment is equipped with a muffler with light structure and more convenient installation. Aiming at different objects of sound attenuation, special TDb type backpressure steam turbine exhaust silencer, TDy type deaerator silencer and other series of noise reduction and sound reduction products are designed to meet the requirements of users.
4. TC type muffler special muffler suitable for boiler test drive purge and industrial pipeline installation and maintenance
The TC type pipe flushing muffler is a special type of exhaust muffler and noise reduction equipment developed to reduce the noise generated by the exhaust of the flushing pipe outlet and the exhaust emission during the test run of the power plant boiler. It can also be used for muffler and sound reduction and debris removal of other industrial pipelines and civil pipelines after installation or maintenance.
5. PB series small hole injection muffler suitable for pipeline exhaust gas
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 muffler, through optimized design, its noise reduction index, safety performance and service life are far superior Similar products on the market, can better meet various boilers, pressures of low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical and other parameters of power, metallurgy, petroleum, chemical, textile, paper, food and other industries The exhaust gas (gas) of the container pipeline is vented and the noise reduction of the exhaust steam (gas) of the safety valve and the release valve is required.
6. CF type fan silencer for ventilation duct
The fan is a kind of general mechanical equipment, and its use range is very wide. The production of electric power, mining, machinery, metallurgy, chemical industry and other industries are inseparable from the fan. The noise generated by the fan in operation is often a source of disaster that affects the health of workers and interferes with the environment. In particular, the aerodynamic noise radiated by the air inlets and air outlets of fans in nearby living areas is the main factor that pollutes the environment, causing pollution, and is one of the main targets of noise pollution control by my country's industrial departments.
7. CP type diesel generator exhaust muffler for diesel generator exhaust muffler
Due to its good economy and power performance, diesel generators are widely used in the production and operation of industrial and mining enterprises, because the flue gas emitted during operation contains a certain amount of soot (that is, the black smoke that everyone often sees), The phenomenon is caused by incomplete combustion of fuel. Therefore, conventional vented exhaust mufflers, such as micro-porous plate mufflers and mufflers with sound-absorbing fillers, are absolutely undesirable if they are used in this environment, because they can only perform temporary noise reduction.
